Creep-feed grinding at the highest level
The creep-feed grinding machine with centre column design (central vertical construction) is designed for powerful grinding – for maximum output and efficiency, even with difficult-to-machine materials. Three axes with direct servo drives make the machine the first choice for racks, profiles and demanding formed parts.
Model: JM-615CNC
Technical features
Powerful grinding
Designed for high stock removal – meets the highest demands on output and efficiency.
Centre column design
Central vertical column design (moving construction) for optimum rigidity and accessibility.
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.
Three-axis direct servo drive
Vertical, cross and longitudinal axes: servo motors directly coupled to high-precision preloaded ball screws – fast response, precise infeed, high positioning accuracy.
Flange spindle
High-precision, high-rigidity flange spindle for excellent surface finish and form accuracy.
