Superfinishing machines

The superfinishing of workpieces is a micro machining process which frequently finds application when other production techniques such as fine milling, fine turning, grinding, lapping or polishing can only meet the required characteristics at considerable cost or are simply not able to meet the requirements.

Superfinishing machines are today always used when the highest precision is required of the workpiece to be machined. It is widely known that the functional behaviour of component parts is decisively influenced by the deviation of their machined surface and their geometrical design.

The superfinishing machining is today made with two different process kinematics:

• Superfinishing with oscillating superfinishing tools
• Superfinishing with rotating superfinishing cup wheels

These and the numerous parts which require superfinishing lead to very varied designs of superfinishing equipment and machines:

• Centerless superfinishing machines
• Plunge-cut superfinishing machines (between centres / chuck; stone and tape finishing machines)
• Superfinishing machines with rotating tools
• Superfinishing equipment

All materials which can be cut with geometrically undefined cutting edges such as steel, cast materials and non-ferrous metals with different alloys and degrees of hardness, ceramics, glass, coated surfaces, composite materials and synthetic materials can be machined with a superfinishing process.
