Medium and large format surface & profile grinding machine
This machine line grinds flat and complex profile surfaces of medium and large workpieces. The T-shaped moving column design combined with a one-piece machine bed provides maximum rigidity – the foundation for precise results across the entire clamping surface.
Model: JM-512CNC
Technical features
T-shaped column design
Moving column in T-design – a flexible and rigid construction for grinding flat and profile surfaces.
One-piece machine bed
The base is designed as a one-piece structure, guaranteeing high bending and torsional rigidity as well as high strength.
Double-wall upper frame
The upper frame in double-wall design offers high bending and torsional rigidity.
Fully supported table
The table is fully supported over its entire length – for smooth travel and precise grinding results.
Heavy-duty linear guideways
Vertical and cross axes on heavy-duty preloaded roller linear guideways – backlash-free and precise.
Direct servo drive
Servo motors directly coupled to high-precision preloaded ball screws: fast response, precise infeed, high positioning accuracy.
Double-V slideways
The table guideways are designed as double-V slideways and are precisely hand-scraped.
Proportional hydraulics
Table movement (left/right) via proportional hydraulic drive with analogue speed control.
Flange spindle
High-precision, high-rigidity flange spindle for excellent surface finish.
Separate hydraulic tank
Independent hydraulic tank prevents thermal effects on machine accuracy.
