• Multi-usage, one machine to complete the whole process of metallographic rough grinding, fine grinding, rough polishing and fine polishing.
  • Single point pneumatic holding, no need for sample clamping.
  • Six pieces of Φ30mm samples can be polished simultaneously.
  • PLC independent control for the grinding disc and grinding head. The grinding & polishing parameters like rotation speed, grinding & polishing time, rotation direction, water valve on/off etc. can be set and automatically saved, easy to call.
  • Large touch screen interface, convenient for parameter setting, intuitive state display and easy operation.
  • Stepless speed changing for both grinding disc and grinding head. The rotation direction is switchable between FWD & REV.
  • PLC control for water supply and grinding material dispenser.
  • Working mode:
    (1)  Automatic mode:

According to the sample materials user’s habits, 30 groups of processes can be set and called. Each process can contain 10 steps of process parameters (each process is corresponding to certain grinding or polishing process. Process parameters: rotation speed of grinding disc and polishing head, grinding and polishing time, etc.)

(2)  Manual mode:

According to each grinding and polishing process, 30 groups of process parameters can be set and called: grinding disc and polishing head rotation speed, grinding and polishing time, water supply on/off etc.

(3) Setting mode:

Set certain function of equipment separately.

  • Magnetic anti-sticky disc can be replaced easily and it can finish the rough grinding, fine grinding, rough polishing and fine polishing for various samples continuously.
  • The water supply can be controlled by electromagnetic valve. There is automatic water cleaning device under grinding disc and it can clean the inside wall automatically.
  • Grinding head automatic electromagnetic lock, no need for manual locking handle.
  • Multi-language interface is available.
  • High accuracy, stable running, low noise.
  • Grinding & polishing dispenser is optional.
  • Operation by mobile remote control device is optional.
