<ul><li>Ideal for tool and die construction, mechanical production, design processes. laboratories and training</li></ul><ul><li>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</li><li>Three-Point Bearing
The custom three-point bearing of the grinding spindle ensures minimum temperature effects and consistent grinding quality.</li><li>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.</li><li>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.</li><li>Speeds
The headstock operates at 3 different speeds (110, 200, 300 rpm) which are set through an easy to operate gear shift lever.</li><li>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
- electrical components are mounted easily accessible in a control cabinet</li></ul> </div>
