A cylindrical grinder has a grinding (abrasive) wheel, two centers that hold the workpiece, and a chuck, grinding dog, or other mechanism to drive the work. Most cylindrical grinding machines include a swivel to allow the forming of tapered pieces. The wheel and workpiece move parallel to one another in both the radial and longitudinal directions.
Transfer of power to the track is accomplished by a drive wheel, or drive sprocket, driven by the motor and engaging with holes in the track links or with pegs on them to drive the track. In military vehicles, the drive wheel is typically mounted well above the contact area on the ground, allowing it to be fixed in position.
The M915 is the namesake and basis of a tactical truck series, although it is not tactical itself. It is a commercial type conventional 6x4 rear wheel drive 14-ton semi-tractor designed for use on improved roads. A powered front axle and other tactical equipment are not needed for this role, allowing a lighter and simpler truck.

The 5‑ton 6x6 truck, officially "Truck, 5-ton, 6x6", was a class of heavy-duty six-wheel drive trucks used by the US Armed Forces. The basic cargo version was designed to transport a 5-ton (4,500 kg) load over all roads and cross-country terrain in all weather.
A schematic diagram of the centerless grinding process. Centerless grinding is a machining process that uses abrasive cutting to remove material from a workpiece. [1] Centerless grinding differs from centered grinding operations in that no spindle or fixture is used to locate and secure the workpiece; [2] the workpiece is secured between two rotary grinding wheels, and the speed of their ...
The grinding head can travel across a fixed workpiece, or the workpiece can be moved while the grinding head stays in a fixed position. Fine control of the grinding head or table position is possible using a vernier calibrated hand wheel or using the features of numerical controls.
Surface grinding is done on flat surfaces to produce a smooth finish.. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or nonmetallic substance from a workpiece, making a face of it flat or smooth.
