Circular knife grinder
The circular knife grinder RM 70 differs from RM 40 only regarding max. grindable workpiece diameter.
It can be used for production and sharpening of:
- Rotary / circular knives
- Circular saws
- Slitting blocks
- Multi knife blocks
- Top slitter knives
- Rotary slitter knives
- Polygon knives
The machine is suitable for application of ceramic, CBN- and diamond grinding wheels. In order to meet the whole variety of manufacturing tasks, the machines can be equipped with a manual loading and standard control in the simplest version up to a fully automatic unit with automatic loading. In either case, most modern manufacturing and control methods guarantee a very high quality of your knives for a long time.
Economy is guaranteed by:
- Minimized setting time
- Optimized grinding efficiency
- Longevity
- Highest precision
- Maintenance-friendly design
