Hard Part Machining
The alternative for grinding
Hard machining by turning instead of grinding is opening up economical advantages and flexibility in many applications e.g. when machining chilled cast iron or hardened steel.
- Shorter machining time.
- Higher flexibility regarding the design of the workpiece to be machined.
- Finish machining of complex contoures in one set-up on one CNC-machine tool.
- Minimizing the number of machining operations within the process chain from raw part to finished part. Grinding sludge will be avoided.
Hard part turning
In hard part turning case-hardened steels or full-hardened steels are machined.
The grinding operation is either substituted completely by turning
(”turning instead of grinding“) or at least the costly coarse
grinding can be replaced (”turning before grinding“). Typical
machining examples are bearing seats on shafts, bores and contoures of gears,
sleeves and rings and races of ball bearings.
