Functional Qualities and Application of Hydraulic Presses

March 7, 2018
Definition and Characteristics of Drills

Hydraulic presses are devices which use hydraulic cylinders for the purpose of generating force. The output of hydraulic presses is equivalent to that of mechanical levers. The hydraulic press concept is derived from Pascal’s theory. The theory holds that upon application of pressure against fluids in a system that is enclosed, pressure generated in the entire system is always constant i.e. pressure remains unchanged throughout. This simply means that hydraulic presses are machines that apply pressure employed against fluids in the crushing of materials. Hydraulic press was invented by Joseph Bramah. This is why it is often referred to as Bramah Press.

Functional qualities of Hydraulic presses

Bearing in mind that Pascal’s law is the principle behind hydraulic presses, the functions of this machine are comparable to those in a hydraulic system. Hydraulic presses contain basic components typical of any hydraulic system. The components include hydraulic pipes, pistons, and cylinders etcetera. The press functional qualities are simplistic. Hydraulic presses contain 2 cylinders. A fluid which often is oil is put inside the cylinder with a smaller diameter. This cylinder is referred to as ‘slave cylinder.

This cylinder has a piston which is pushed in order to compress fluid contained inside. The fluid moves through pipes connecting this cylinder to a larger cylinder. This bigger cylinder is referred to as ‘Master cylinder.’ Pressure exerted on larger cylinder alongside the attached piston causes the fluid to travel back into slave cylinder.

The force exerted on slave cylinder produces an even bigger force when exerted against master cylinder. Hydraulic pressure generated in the process is often useful in industrial application where large amounts of pressure are needed for functions such as metal compression. Hydraulic presses used for industrial applications utilize material that required to be pressed alongside press plates which punch or crush materials into smaller sheets.

Hydraulic Presses can be used to build custom walk decks just like Firesky Coatings: http://www.fireskycoatings.com/

Hydraulic presses types

Different hydraulic presses are used for different purposes. Here are some.

Laminating Presses-These types of presses use manual labor to operate unlike other hydraulic presses. They do not use much pressure to produce the desired output. They have 2 opening referred to as plates. Both have different functions, one for heating and the other for cooling. Laminating presses can quickly laminate polymers against metal or paper surfaces. Plates are often heated using electricity or oil.

Arbor Presses: They are often used to execute duties that are not heavy in nature. These hydraulic presses do not employ much pressure for desired output in comparison to industrial hydraulic presses. They often are used for making holes on metals, flattening metals, marking inscriptions and stamping.

Pneumatic presses: Relative to other hydraulic presses, these are a basic type for industrial purposes. They often use air to generate pressure for movement. They are advantageous in that they perform operations much faster although they cannot generate high pressure like other hydraulic presses would. They are used in aircraft and car braking systems. Some of their industrial use includes punching, drawing and assembling.

Assembly presses: These use extreme pressure from hydraulic fluids in the maintenance and assembly of parts.

Power Presses: They are applied in big industries requiring heavy equipment and machinery. Power presses can be of two distinct types. There is the part and the full revolution power presses. Due to the magnitude of operation involved power presses are quite dangerous. Safety precautions have to be taken while operating them.

Other types: H-Frame and C-Frame Hydraulic presses etcetera.

Common uses

Processing cocoa beans: Chocolate liquor is extracted from coca beans through squeezing. Hydraulic presses are used for this purpose. The liquid is processes further to make cocoa powder.

Crushing of cars-Car crushing system is often hydraulic driven. Large pressure is applied against vehicles.

Sword making: The objective of using hydraulic presses during sword making is to flatten raw metal for a perfect sword.

Types and Purposes of Shaping Machines

Grinder Types and Functions

Shaping machines are used for the purpose of machining surfaces. It could cut angles, curves and many different types of shapes. The machine is quite popular in workshops owing to the simple movements. It could produce different versions of work. Shaping machines are manufactured in different sizes as well.

Modern shaping machines can produce contoured designs to surfaces. This is made possible through rigid holding of work pieces on machine followed by reciprocating shaping motions from a distinctly shaped tool attached on the head of shaping tool. This tool travels on horizontal axis along the working piece. Metal shapers also exist.

Purpose and significance

Through chipping the shaping machine cuts work pieces into desired shapes, surfaces and dimensions as would be desired. They often yield flat surfaces, grooves, shoulders and identical shapes. It is possible to produce arched or circular shaped surfaces as well. Shaping machines use distinct tools for cutting with return stroke and working stroke. The process of shaping requires interplay of turning and shaping of working pieces in order to produce a desired outcome. Shaping is often done with an objective of eliminating substantial quantities of material in chips form. The shaping process removes iron scales from metal surface and aligns surfaces. It also involves cutting heavy or long sections of material for the purpose of shaping plate edges etc.

Shaping is often accompanied by other processes such as scrapping and grinding for the purpose of achieving surface excellence.

Shaping machine types

Crank shaper: This is a common shaping machine. The ram motions in a crank machine come from a crank, crank pin and crank block. The size of the shaper will be known through the ram’s biggest stroke. The stroke range is usually between 12inches and 36 inches. The 24 inch stroke is the most conspicuous.

Gear shaper: The ram’s reciprocating movements on hydraulic shapers come from pinion and rack. The direction and speed of movement by the machine is dependent on the gears found in gear train. This shaper type is not common.

Horizontal shaper: The tool used to hold the ram in horizontal shapers reciprocates on horizontal axis. The horizontal shapers will often yield flat surfaces.

Hydraulic Shapers:  Reciprocating movements of hydraulic shapers are derived from hydraulic power. This shaper operates with oil pumped into cylinder with high pressure. The cylinder has a piston for control. The piston end is attached to the shaper’s ram. High pressure works on either side of piston therefore making reciprocating motion on piston. The reciprocating motion gets transferred to ram. The speed of piston changes through adjustments of oil quantities delivered through shaper pump. This shaper is advantageous in that the force and speed of cutting on ram drive is unchanged from start to completion of cutting.

Vertical shaper:  the ram on which the tool is attached on a vertical shaper rotates on vertical axis. Some vertical machines have some provisions allowing for adjustment of Ram for up to 1000 on vertical position. The shapers could be rack, crank, hydraulic or screw driven.

Other types of shaper machines: Plain or standard shaper, travelling head machine, universal shaper, draw shaper, and push shaper machine.

Categories & Functions of Milling Machines

March 14, 2018
Boring Machines

Milling machines and Computer Numerical Control systems (CNC) are used in milling of different types of gears and surfaces etcetera from metal surfaces or other types of surfaces. These machines are conspicuously universal in the manufacture of gears among other things. Universally applicable milling machines could be applied in different types of drilling, reaming and milling of steel metals and other types of metals. They can be used in medium or low quality production series.

Functional qualities of milling machines

Milling machines will regularly be automated and could function from a horizontal or vertical position in curving out of materials based upon an already existing design. Most milling machines are directed by CAD and are controlled by CNC systems. Conventional and manual milling devices are also in common use. Milling machines have capacity to move dynamically both for the work piece and the tool. Most milling machines will also perform machining on multiple axes. Due to the differences in orientation, application and operation, milling machines will often have a variety of functionalities and differences in principles of operation.

Tooling: The milling machine could be fitted with various tool heads with an objective of meeting varying machining needs. The different tool heads may include ball end, fluted, rounding and cutters mills. Some of these machines have tool ends that rotate and could be changed based on the prevailing need. A computer program is designed to communicate when a change of tools is needed.

Tools are picked depending on desired shape and material in use. Since materials such as steel, plastic and wood have varying physical characteristics, a variation in tool bits used is necessary. This ensures materials are properly machined. In case the tool bit used does not meet the strength quality needed for steel machining, both the machine and tool could get damaged. Tool bits that are stronger than material could as well damage work pieces.

Milling machine types

Categories of milling machines are identified based on the work pieces and motion degree.

Plain Horizontal and vertical Machines: These are milling machines that have typical working surfaces with horizontal or vertical orientation. Tooling equipment is usually fixed on swivel or turret. The tools are placed in parallel positions to work space. Swivel and turret makes it possible for free tool movement around work piece area in order to allow for tolerance of force.

Knee Type machines:  They operate in a vertical position with support from a knee. The knee is adjustable. This knee offers support to a saddle and allows for adjustments in order to customize a work space depending on the needs.

Universal Ram Machines: Ram type machines are used in order to make it possible for tooling equipment to take position on larger spaces in relation to a work piece. This machine has spindle placed on movable housing. The spindle could move on some horizontal plane. This category of milling machine entails some swivel housing capable of increasing the scale of movements for cutting.

Swivel Cutter Head Ram: This milling machine has a swivel which rotates from an absolute vertical position and down to a horizontal position. Working table is also designed to move accordingly making it possible for user to enjoy liberal orientation and motion. Most swivel cutters have entail hand driven or automatic settings which increases the options of operation.

Universal Horizontal Machine: This machine is different from pain horizontal machine. It houses the table swivel which essentially makes it possible to have the table move for up to 450 from the horizontal position. The movement makes it possible to enjoy easy helical and angular milling functions.

Grinder Types and Functions

Grinder Types and Functions

The grinders or grinding machine is any type of machine or power tool that used for the purpose of grinding. It is a machine type that applies rough wheels as the surface against which objects are cut. Each of the rough grains on the grinding wheel removes a tiny chip bit from work piece through shear deformation process. Through Grinding work pieces get high quality finishes and extreme dimension and shape accuracy. Grinding is often an operation executed during finishing removing small unwanted metal elements. In some applications, however, grinding is used to remove large volumes of metal quite fast. Grinding is therefore a large and diverse field.

The grinder has a bed containing a fixture used for holding and guiding work pieces. The grinding wheel is often power driven making the wheel to spin at a regulated speed. The speed of spinning is dictated by the diameter of the wheel and the rating from grinder manufacturer. The grinding equipment can move along the work piece or alternatively the grinder can be fixed in a stationary position allowing the working piece to move instead.

The table position or grinding head can be controlled with precision using calibrated wheel or by application on CNC features. Grinders eliminate work piece materials through abrasion or scraping. The friction generates large amounts of heat. In order to cool down the material with an objective of alleviating overheating, the grinder has a coolant tool installed with it. Overheating can go beyond the tolerance ability of the machine or work piece were it not for the coolant. This coolant also protects the machine operator from burns. Grinders that use high levels of precision usually remove very minute elements in every pass. The heat generated in such circumstances is very minimal. Even without a coolant the levels of heat generated are negligible.

Grinder types

Bench Grinders: This grinder has 2 sets of wheels with distinct sizes of grain for the purpose of finishing and grinding functions. This grinder is fastened on a floor stand or work bench. Some of its functions include tool bits shaping or repair of various tools. These grinders are operated manually.

Belt Grinders: This grinder is used for the purposes of metal processing and the processing of other materials. The grinder uses coated abrasives for its purposes. Belt grinders are similar to belt sanders. A belt sander is often applied on wood surfaces although at times on metal surfaces. The process of belt grinding is handy and applicable in different settings including stock removal and deburring.

Angle Grinders: Also referred to as Disc or Side Grinder. This grinder is often hand held and electric powered. It is applied in polishing and grinding. The angle grinder was originally developed for grinding abrasive discs they are now used with large varieties of attachments and cutters.

Cylinder Grinders: These grinders may use centers and may have many grinding wheels. Work pieces are rotated and inserted along the wheel in a cylindrical form. This grinder is applied in making accurately designed bushings, bearing races, tubes, and precision rods.

Gear Grinders: This is often the tool used for final processes of machining when making gears of high precision levels. The main function of a gear grinder is to eliminate the small minute materials that were left after manufacture like the hobbling or gashing.

Other Grinders include: Surface grinder, die grinder, cutter and tool grinder, and Jig grinder.

Definition & Characteristics of Drills

February 21, 2018
Definition and Characteristics of Drills

Drills or drill machines are tools are used for cutting holes through materials such as metal, plastics, wood and other surfaces. A drilling machine utilizes a tool for drilling. The drilling tool contains cutting edges on the pointed end. The tool is fitted in the drill machine using a Morse or Chuck taper. The drilling tool rotates in regulate speed through working pieces. A drill can be used to carry out other functions. Drills can be used in boring, reaming, tapping, spot facing, and counter boring. The drill operator must understand the work set up, feed and set speeds. They also must have a coolant in order to get a desired outcome. Friction from grinding tools may cause overheating hence altering or destroying drill and work piece.

Capacity and size of drills are determined by available largest stock pieces that could be drilled at the center.  The drill size could also be determined by largest size of hole that could be drilled, the vertical space between spindle and worktable and length between column and spindle.

Drill machines are often used in metal working, woodworking, DIY and construction projects. Special drill designs are applied in space missions, medicine and such like applications. There are different drill makes specific to certain performance needs determined by capacity and power.

Characteristics of Drills

All Drills have common construction qualities such as the quill or sleeve, base, worktable, column and spindle.

Spindle: This component is used as cutting tool or for holding the drill. It revolves on a stationary sleeve position. Most drills have the spindle in vertical positions and the horizontal table supports working Piece.

Sleeve or Quill: This component doesn’t revolve although it could slide on its own bearing in parallel axis direction. When spindle anchoring the cutting tool carried by a sleeve is brought down, this cutting equipment is forced against the working material. The pressure forced against the sleeve by power or hand makes the drill, which is revolving, to force its way inside the work piece in bits for every revolution.

Worktable: The support to the worktable comes from a mounted arm. The arm is mounted against the column.  Worktables are adjustable vertically.  This allows the table to handle varying work heights. The worktable could also be swung to move from position. The tilting can go for a maximum of 90 degrees in both directions. This makes it possible for lengthy pieces to be drilled at an angle or by their ends.

Column: Most drills have the column with circular presses. They are often built solid and rugged. Columns are used in supporting the quill or sleeve and head assemblies.

Head: a drill head is made of spindle, sleeve, feed, and electric motor mechanisms. The head will be fastened on the column with bolts.

Base: The drill has a base which supports the whole machine. When fastened on floor surface using bolts, it helps achieve top accuracy and alleviates vibrations from the machining process. The base has a top similar to that on worktables. It could contain T-slots used for fastening excessively large work pieces on -such that cannot be mounted on a worktable.

Types and Characteristics of Boring Machines

February 14, 2018
Boring Machines

The boring machine is used in milling, cutting threads, boring, face turning or drilling. They use some rotating tool, more so a milling head, boring rod, drill or cutter. These machines are often used in drilling of open or closed surfaces of solid material, milling, threading, reaming or boring surfaces etcetera. The tools used in carrying out this operation include the milling cutters, thread cutters, reamers, drill bits and such like tools. One of the boring machines is the one that uses a horizontal spindle to bore. These machine types are known as horizontal boring machines. The horizontal spindle moves along their axis in order to bore through a Computer Numerical Control (CNC) System.

Boring machines are known to produce accurate and smooth holes on work pieces through enlargement of already existing holes by use of bores. The bores may be made of steel cutting tips, diamond or cemented carbide. The bore could also be a tiny wheel for grinding. Solitary tools are gripped against boring heads and attached against rotating spindles. The rotating spindle moves in circular motions against the walls of existing holes. The diameter to the hole is swept by this boring tool. The tool is under the control of boring head.

The cutters to the grinding wheel move in planetary motion and they rotate fast on their axis. The rotating wheels also move in slow motions with the rotation of the machine’s boring head on spindle axis. The diameter to the hole is managed through distance adjustments between spindle axis and wheel axis. The boring machine spindles can rotate on horizontal or vertical axes.

The tool making boring machines have a vertical spindle and a single material holding table. The holding table can move horizontally in separate and perpendicular directions to one another in order to allow for accurate spacing of holes. Some machines have spacing errors lower than 0.002%. For purposes of mass production distinct boring machines with many spindles are commonly used.

Types of Boring Machines

Boring machines can be categorized into four groups. There are: Horizontal, vertical, Jig and precision boring machines.

– Horizontal: Multiple head, Planer, floor and table boring machines
– Vertical: Standard vertical and Turret lathe boring machines
– Precision
– Jig Boring Machines: Planer and vertical milling machines

Jig Boring Machines

This type is considered incredibly accurate. It was initially developed in 1910 from Switzerland. These machines are currently used for tools, fixtures, jigs and precision parts production. Essentially a jig machine is used to produce products that require high levels of accuracy and precision. The exceptional levels of accuracy are achieved through low levels of thermal expansion high rigidity with the machine and accurate measurement of the space and location where holes are to be made. The jig machine cuts metals for slots, planes and holes finishing using accurate surface or center location without any special attachments used for alignment of tool.

All parts of a jig machine are tremendously rigid in order to make sure there is minimal vibration and deflections. Spindles role in predetermined bearings and in the process they resist friction. The jig machine needs a room with controlled temperature in order to operate effectively.
