Used Grinding machines

Grinding machines are machine tools used for grinding which is a type of maching using an abrasive wheel as the cutting tool. Each grain of abrasive on the wheel's surface cuts a small chip from the workpiece via shear deformation.

Construction

Grinding machines consist of a power driven grinding wheel spinning at the required speed (which is determined by the wheel’s diameter and manufacturer’s rating, usually by a formula) and a bed with a fixture to guide and hold the work-piece. The grinding head can be controlled to travel across a fixed work piece or the workpiece can be moved whilst the grind head stays in a fixed position.

Grinding machines remove material from the workpiece by abrasion, which can generate substantial amounts of heat; they therefore incorporate a coolant to cool the workpiece so that it does not overheat and go outside its tolerance. The coolant also benefits the machinist as the heat generated may cause burns in some cases. In very high-precision grinding machines (most cylindrical 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 - this generates so little heat that even with no coolant, the temperature rise is negligible.

Types of grinding machines we do have to offer:

• Cylindrical grinding machines (universal, inner, outer and centerless)
• roll grinders

Please provide us with the following basic data and we would be pleases to offer you selected grinding machines:

- grinding diameter in mm
- grinding length in mm
- max. work-piece weight in KG or tons
- center height in mm
