Our CNC jig grinding machines are designed for ultra-precision grinding of hardened contours and hole systems. They combine continuous-path interpolation with point-to-point CNC control, making them suitable for mould cavities, punch forms and precision templates.
Representative models such as NJ-MK4280/1 and MK2945C are equipped with HEIDENHAIN linear scales and SIEMENS CNC, ensuring nanometre-level feedback and stable motion control. A hydrostatic planetary spindle, dual linear motors and a high-speed electric spindle support sub-micron roundness and micron-level hole-spacing accuracy. Optional wheel/workpiece measurement, wheel dressing units and tool magazines enable the creation of a high-efficiency, intelligent "jig grinding center."
These capabilities allow our CNC jig grinding machines to support demanding precision-finishing environments, helping manufacturers achieve consistent, high-quality results across complex part geometries.
This CNC jig grinder supports continuous-path machining for hardened mould cavities, templates and punches, generating precise curves using linear and circular approximation. It also performs high-accuracy point-to-point grinding for hardened coordinate hole systems with tight spacing requirements.
This CNC jig grinder supports continuous-path machining using linear and circular approximation to process hardened templates, mould cavities and punch profiles with arbitrary curve shapes. It also performs high-accuracy point-to-point grinding for hardened coordinate hole systems that require precise hole-spacing control.

The NJ-MK4280/1 jig grinding machine includes six axes: X, Y, Z, W, U and C. It supports three-axis simultaneous interpolation, where any three among X, Y, C and A can work together to generate complex curves. This allows grinding of quenched templates, mould cavities and punches with arbitrary curve profiles using linear or circular approximation.
The jig grinding machines achieve 0.005 mm positioning accuracy and 0.003 mm repeatability in X and Y axes. Adjustable wheel speed and feed settings support ultra-precision machining, making the equipment well suited for scientific research and experimental applications.
