> CG12CNC-5A 5 axis CNC Centerless cylindrical grinding machine

This grinding machine is driven by a servo motor, allowing for fine-tuned feed. A servo system can be added for touchscreen control, facilitating grinding process co05ntrol and easier dimensional adjustments.
The machine utilizes a CNC system for simpler, more user-friendly operation, programmable control, and precise grinding feed settings.
Automatic trimming and correction functions can be added, and a cantilever gantry robot or unmanned robot can be installed to achieve unmanned grinding.

Cylindricity: ≤0.002mm
Surface Roughness: Rz≤0.3μm


Long-lasting
Durability

Japan's premier grinding machine manufacturer employs advanced technology suitable for machining medical guide wires, shafts, pins, rollers, sleeves, rings, slender shafts, thin-walled components, simple stepped shafts, and multi-stepped small shafts. Materials include ceramics, alloy steel, bearing steel, tool steel, mold steel, copper, aluminum, high-temperature alloys, and cemented carbide. Ideal for automotive parts, aerospace, and other industries.





Double V-shaped guide rails + dovetail groove structure, capable of ±5 degrees rotation with feed adjustment precision down to 0.001mm.

Hydraulic drive, continuously variable transmission, and smooth dressing significantly enhance straightness and surface roughness during grinding.
