Characteristics of CNC grinding

Modern CNC grinding machines are characterised by a number of special features that clearly distinguish them from conventional machines:

• Micrometre-precise vertical positioning: The position in the vertical direction is displayed with a resolution of 0.1 µm. The infeed stroke can be programmed so that the machine stops automatically at the specified position.
• Precise tolerance control: Tolerance levels of 10, 20 or 30 µm can be preset – for reproducible results across the entire series.
• Automatic spark-out programme: Up to five programmable spark-out passes remove the last elastic spring-back from the system and deliver dimensionally accurate surfaces.
• Precise table stop: At the touch of a button, the worktable stops at the pre-programmed position – for repeatable machining sequences.
• Automatic lubrication on the gravity principle: The guideways are lubricated reliably and evenly – without additional pump energy, maintenance-friendly and fail-safe.
• Automatic infeed in the 0.1 µm range: Fine infeed in the sub-micrometre range is easily possible with the CNC control – the basis for the highest surface qualities.

These features make CNC grinding machines the first choice when it comes to repeat accuracy, surface quality and economy in series production.
