Ideal for tool and die construction, mechanical production, design processes. laboratories and training
The functionality of the Multi-Grind ranges from external and internal cylindrical grinding to taper grinding. The Multi-Grind also allows easy tool grinding (sharpening of cutters, reamers and turning tools) and is suitable for light surface grinding job
Three-Point Bearing
The custom three-point bearing of the grinding spindle ensures minimum temperature effects and consistent grinding quality.
Feed Drives
Hydraulic table feed (longitudinal) with automatic change of direction. An additional manually operated longitudinal feed with hydraulic support allows feed speeds up to 275"/min.
Grinding Headstock Special grinding headstock design allows simultaneous setup of 2 different grinding wheels. The grinding headstock can be moved in transverse direction and also vertically; and it can be rotated around the vertical axis.
Speeds
The headstock operates at 3 different speeds (110, 200, 300 rpm) which are set through an easy to operate gear shift lever.
Additional Features...
- central lubrication system
- sturdy construction - the KNUTH Multi-Grind body is made of solid cast-iron and weight 2860 lbs; minimizes vibration effects
