Compact surface & profile grinding machine with cross-slide design
The compact surface and profile grinding machine in cross-slide design is the ideal solution for small and medium workpieces – from simple flat grinding to demanding formed profiles. The finite-element-optimised machine bed guarantees highest precision over many years.
Models: JM-410CNC / JM-52CNC
Technical features
Cross-slide machine bed
Bed designed with finite-element analysis. The base in square double-wall construction with multiple ribbed structure increases rigidity and stability.
Double-wall upper frame
The upper frame in double-wall design (centre construction) offers high bending and torsional rigidity.
Double-V slideways
The guideways for the table movement (left/right) are designed as double-V slideways, ensuring smooth table travel and highest grinding accuracy.
Heavy-duty linear guideways
Vertical and cross axes run on heavy-duty preloaded roller linear guideways – for backlash-free, precise infeed movements.
Direct servo drive
Servo motors for vertical and cross axes are directly coupled to high-precision preloaded ball screws – fast response, precise infeed, high positioning accuracy.
Proportional hydraulics
The table movement (left/right) is driven by a proportional hydraulic drive with analogue speed control – infinitely variable and uniform.
Flange spindle
High-precision, high-rigidity flange spindle for excellent surface finish and form accuracy.
Separate hydraulic tank
An independent hydraulic tank prevents hydraulic heat from affecting machine accuracy.
