Valve combination grinding machineTS-DGWMC-400A)

1. The traditional three-step process or even more processes can complete the work, ensure the shape and position tolerance of the relevant parts, bring cumbersome clamping, equipment precision, personnel quality and cost requirements to each process; now adopt servo control Multi-axis feed, product rotary fit, thimble auxiliary support, high-speed grinding of forming CBN grinding wheel, R-shaped, disc outer diameter, end face and chamfering are processed in one position, and the other conical surface rough grinding is processed; the processing station can be selected. The processing cost is greatly reduced, the production is convenient, and the management is convenient.

2. The processing process is divided into rough grinding, fine grinding and light grinding to meet the requirements of each processing section.

3. Another configuration suitable for valve production needs, automatic feeding and discharging device, digital display to intuitively understand and control various processing parameters; warning lights, warning information to remind users of hidden dangers, reduce labor intensity; and various safety configurations, Forced to remind you of correct and safe operation;

4. Special collectors for oil mist smoke, magnetic separators, filter tanks and fully enclosed protective covers play an effective and positive role in environmental protection.
