Grinding is one of the oldest machining processes which accounts for about 25% of the total expenditure of machining operations in industry. It is mostly used in finishing operation of the parts to achieve the required final geometry, tolerance integrity and surface quality. For some special cases, it is also possible to use grinding technology to perform roughing operations, e.g. for ...
2.1. Select grinding wheels based on shape and grit/bond composition and dress to form and size, as required. 2.2. Set up work to required level of accuracy according to specifications. 3. Perform complex grinding. 3.1. Perform specialised grinding operations on components. 3.2.
In this process, the workpiece is fixed to the bottom of the machine and the grinding wheel moves down to grind the piece. The wheels are also capable of axial rotation, which means they can rotate and grind lips and bevels. Depending on the shape of the workpiece, vertical grinding can perform ID, OD, and surface grinding operations. Features
cylindrical grinding machine. The work is fed longitudinally against the rotating grinding wheel to perform grinding. The upper table of the grinding machine is set at 0° during the operation. 4.5.2 Taper grinding Taper grinding on long workpieces can be done by swivelling the upper table. If the workpiece is short, the wheelhead may be ...
End-feed Grinding. In the end feed of centerless grinding, the workpiece is axially fed into the machine tool along one side and rests on the end stop. Perform the grinding operation, and then feed the workpiece in the opposite direction to exit the machine tool. ) Face feed grinding is most suitable for tapered workpieces.
4. Perform grinding operations. 4.1. Grinding machine is set up and adjusted in accordance with defined procedures. 4.2. Work piece is held or clamped appropriately to avoid damage. 4.3. Grinding operations are performed safely, utilising all guards, safety procedures and personal protective clothing and equipment. 5.

The Environmental Compliance Coordinator (ECC) shall perform or designate personnel to perform inspections. The ECC shall ensure deficiencies noted during the inspections are corrected immediately. Actions taken to correct each deficiency shall be recorded on the inspection sheet. Welding/Grinding Operations – Inspection Checklist Date: Time:
The fundamental design is the same in both cases, but the universal machine can be adapted for internal grinding operation as well. In cylindrical grinding machine operation, the work is mounted between two centres and is rotated. A grinding wheel is mounted on a spindle and revolves at a higher speed than the work.
Wear goggles for all grinding machine operations. Check grinding wheels for cracks (Ring Test Figure 5-11) before mounting. Never operate grinding wheels at speeds in excess of the recommended speed. Never adjust the workpiece or work mounting devices when the machine is operating Do not exceed recommended depth of cut for the grinding wheel or ...
5. Other Machining Operations • Shaping and planing – A single-point tool moves linearly relative to the work part – Shaping - A tool moves – Planing – A workpart moves • Broaching – Performed by a multiple-tooth cutting tool by moving linearly relative to the work in the direction of the tool axis. • Sawing
