Valve Spool Machining
Centerless cylindrical grinding
Tight tolerances even with the critical shapes of a valve spool
- Match grinding application: pre-process measuring of sleeve/automatic offset of inprocess measuring units.
- Grinding with conventional abrasive wheel.
- Automatic taper correction commanded by inprocess measuring units.
- Rotary B-axis with integrated brushing unit for deburring.
- Excellent quality results based on linear motor repeatability and thermal stable granite bed.
- OD grinding, in infeed or throughfeed, depending on the customer production requirements or part shape if different diameters must be ground.
- Cylindricity: < 0.0015 mm
- Diametrical tolerance: 0.002-0.0025 mm.
- Surface finish: Ra 8.
