Grinding Machines

BW Machine Tools have been specialising in used grinding machines since 1970, to find out more about what kind of machines we stock, read below:

What is a grinding machine?

Grinding machines are made up of a power driven grinding wheel spinning at the required speed and a bed with a fixture to guide and hold the work-piece. The grinding head is controlled to allow travelling across a fixed work piece, or the workpiece can be moved whilst the grind head stays in a fixed position. For extra control of the grinding head or tables position, use of a vernier calibrated hand wheel, or the features of NC or CNC controls is possible.

Grinding machines remove material from the workpiece through abrasion. This can generate a lot of heat. The machines incorporate a coolant to cool the workpiece so that it does not overheat and go outside its tolerance.

In high-precision grinding machines (most cylindrical grinders and surface grinders) the final grinding stages are usually set up so that they remove about 2/10000mm (less than 1/100000 in) per pass - thus generating less heat so that even with no coolant, the temperature rise is negligible.
