5-Axis 6-Station CNC Polishing Machine
Description
This equipment can process six identical workpieces simultaneously in one operation, and the workpieces can continuously complete 4 grinding processes without re-clamping, offering significant market competitiveness in terms of production efficiency and cost. It is applicable to polishing plastics, aluminum alloys, stainless steel, titanium alloys, and other materials, boasting a wide range of applications. Customers can also optionally purchase our 6-axis CNC polishing equipment and automatic workpiece loading/unloading solutions.
- Five-axis simultaneous linkage with 6 independent C-axes on the workbench, ensuring high precision and suitability for curved surface grinding;
- Six-station layout enabling simultaneous processing of 6 workpieces for high efficiency;
- Six independent Mini Y-axes and Mini Z-axes, with each station allowing individual zero-point calibration in Y and Z directions to guarantee processing consistency across all six stations;
- Six independent sets of Y/Z dual force control systems for enhanced polishing quality;
- High-rigidity cast iron machine body structure ensuring stable machine performance;
- Four-side grinding head enabling continuous completion of 4 polishing processes with one-time clamping;
- Wide compatibility supporting polishing of workpieces with a maximum diagonal of 243mm;
- Applicable materials: plastics, aluminum alloys, stainless steel, titanium alloys, etc.;
- Reusable with clean water, cutting fluid, and other liquids;
