Features of horizontal CNC grinding machines

Modern horizontal CNC grinding machines convince with well-thought-out design features that promote precision and productivity alike:

1. All-cast structure: Bed, machine feet and oil pan are designed as a one-piece casting. The high rigidity and good vibration damping meet the requirements of high-speed grinding.
2. Three-point spindle bearing: The headstock is designed with three bearings, all as tapered roller bearings. The spindle is easy to adjust, has high run-out accuracy and retains its precision over a long period.
3. Changeable thread unit: The feed gearbox offers a changeover between metric and inch threads – the selection of the thread type is reliable and convenient.
4. Cone clutch safety device: In the carriage housing, a cone clutch protects the machine against overload damage during automatic feed.
5. Automatic longitudinal feed with 4 positions: Via the mechanical stop device, the workpiece length and thus the longitudinal feed can be set exactly – for dimensionally accurate longitudinal machining.
6. Speed change on the tailstock: Meets the requirements of drilling and reaming operations.
7. Well-designed lubrication system: Headstock, feed gearbox and carriage housing are supplied via splash lubrication; special areas additionally receive automatic forced lubrication via gear and piston pumps.

These design principles are also found in the CNC grinding machines of the JM series – robust, precise and designed for durability.
