Feb 02 2015nbsp018332The versatility and wide application of the grinding processes have led to the development of many types of grinding machines. Your shop will probably have two three or more of the common types. As a machinist you should be familiar with the many types of these machine tools and the processes they perform.
Nov 01 2019183 Surface Grinding Machine. A third type of grinding machine is a surface grinding machine. Surface grinding machines are unique because they feature an adjustable head. The head on a surface grinding machine can be lowered down to the workpiece. Once lowered the head can then rotate back and forth under the machines grinding
This machine may be similar to a milling machine used mainly to grind flat surface. However some types of surface grinders are also capable of producing contour surface with formed grinding wheel. Basically there are four different types of surface grinding machines characterised by the movement of their tables and the orientation of grinding wheel spindles as follows
Horizontal spindle and reciprocating table Vertical spindle and reciprocating table Horizontal spindle and rotary table Vertical spindle and rotary table
Figure illustrates this machine with various motions required for grinding action. A disc type grinding wheel performs the grinding action with its peripheral surface. Both traverse and plunge grinding can be carried out in this machine as shown in Fig.
This grinding machine with all working motions is shown in Fig. 29.3. The grinding operation is similar to that of face milling on a vertical milling machine. In this machine a cup shaped wheel grinds the workpiece over its full width using end face of the wheel as shown in Fig. 29.4. This brings more grits in action at the same time and consequently a higher material removal rate may be attained than for grinding with a peripheral wheel.
Surface grinding in this machine is shown in Fig.29.5. In principle the operation is same as that for facing on the lathe. This machine has a limitation in accommodation of workpiece and therefore does not have wide spread use. However by swivelling the worktable concave or convex or tapered surface can be produced on individual part as illustrated in Fig. 29.6
The principle of grinding in this machine is shown in Fig. 29.7. The machine is mostly suitable for small workpieces in large quantities. This primarily production type machine often uses two or more grinding heads thus enabling both roughing and finishing in one rotation of the work table.
The concept of single pass deep grinding at a table speed much higher than what is possible in a creep feed grinder has been technically realized in this machine. This has been made possible mainly through significant increase of wheel speed in this new generation grinding machine.
TYPES OF MILLING MACHINES KNEE-TYPE MILLING MACHINE Knee-type milling machines are characterized by a vertically adjustable worktable resting on a saddle which is supported by a knee. The knee is a massive casting that rides vertically on the milling machine column and can be clamped rigidly to the column in a position where the milling head .
Dec 01 2016nbsp018332Some builders classify their machines by the type of grinding zone. With moving-zone or three-slide machines the grinding wheel is fixed during operation and the X- Z- and B-axis wheel inclination movement is controlled from the regulating side. This arrangement provides a compact design and excellent rigidity.

Hundreds of varieties of metal machine tools ranging in size from small machines mounted on workbenches to huge production machines weighing several hundred tons are used in modern industry. They retain the basic characteristics of their 19th- and early 20th-century ancestors and are still classed as one of the following 1 turning machines lathes and boring mills 2 shapers and planers 3 drilling machines 4 milling machines 5 grinding machines 6 power saws and 7 presses.
Boring involves enlarging and finishing a hole that has been cored or drilled. Bored holes are more accurate in roundness concentricity and parallelism than drilled holes. A hole is bored with a single-point cutting tool that feeds along the inside of the workpiece. Boring mills have circular horizontal tables that rotate about a vertical axis and they are designed for boring and turning operations on parts that are too large to be mounted on a lathe.
Shaping and planing operations involve the machining of flat surfaces grooves shoulders T-slots and angular surfaces with single-point tools. The largest shapers have a 36-inch cutting stroke and can machine parts up to 36 inches long. The cutting tool on the shaper oscillates cutting on the forward stroke with the workpiece feeding automatically toward the tool during each return stroke.
A milling machine cuts metal as the workpiece is fed against a rotating cutting tool called a milling cutter. Cutters of many shapes and sizes are available for a wide variety of milling operations. Milling machines cut flat surfaces grooves shoulders inclined surfaces dovetails and T-slots. Various form-tooth cutters are used for cutting concave forms and convex grooves for rounding corners and for cutting gear teeth.
Milling machines are available in a variety of designs that can be classified as the following 1 standard knee-and-column machines including the horizontal and the vertical types 2 bed-type or manufacturing machines and 3 machines designed for special milling jobs.
Grinding machines remove small chips from metal parts that are brought into contact with a rotating abrasive wheel called a grinding wheel or an abrasive belt. Grinding is the most accurate of all of the basic machining processes. Modern grinding machines grind hard or soft parts to tolerances of plus or minus 0.0001 inch 0.0025 millimetre.
The common types of grinding machines include the following 1 plain cylindrical 2 internal cylindrical 3 centreless 4 surface 5 off-hand 6 special and 7 abrasive-belt.
The machine uses a Fanuc based CNC control system OSP 7000L and programming is carried out manually at the console. . The precision grinding of parallel surfaces in press tooling . Our Technical staff are highly experienced in all types of welding processes

Due to the fact that there are various operations performed on a grinding machine the availability of different types has aided their achievement and effectiveness. Some special types of grinders specifically design for the effectiveness of an operation.
