Model AUTOPOL 2000XP is a kind of double discs pneumatic type automatic metallographic specimen grinding and polishing machine equipped with automatic polishing head and stepless speed changing. It features advanced performance and high degree automation and can finish the whole process of rough grinding, fine grinding, rough polishing and finishing polishing automatically. It is the necessary metallographic specimen preparing instrument for using in factories, scientific research institutes and laboratories of colleges.


  • Individual samples are loaded independently.
  • Central force loading of the sample disc, fix six samples at one time, complete all grinding and polishing processes, and ensure the complete plane of each sample by the grinding.
  • Grinding & polishing disc and sample disc: set and run all grinding and polishing parameters, such as rotating speed, grinding and polishing time, rotation direction, water valve on/off, etc., which are automatically saved and easy to call.
  • Touch screen interface: it is convenient to set grinding and polishing parameters, intuitive status display and simple operation.
  • The rotation direction of both grinding & polishing disc and sample disc can be switched, and the rotation speed changing is stepless.
  • Working modes:

(1) Fully automatic mode:

According to the sample materials or the habits of users, 30 sets of processes (processes) can be set and called, and each process can contain 10 process parameters (for each process, for a certain grinding or polishing process, process parameters: grinding disc and grinding head rotation speed, grinding and polishing time…)

(2) Single operation mode:

According to each grinding and polishing process, 30 process parameters can be set and called: grinding disc and grinding head rotation speed, grinding and polishing time, water on-off

(3) Manual mode:

Operate a function of the equipment separately

  • Four channel automatic dispenser (optional):

(1) The main machine of the grinding and polishing machine controls the four channel dispenser.

The type and speed of dispenser are controlled by the grinding and polishing machine.

(2) There are three working modes of the dispenser: manual, online and automatic.

(3) Connect the dispenser with the grinding & polishing machine and drip liquid according to the

parameters set by the grinding and polishing machine. Each mode can set dripping speed and

dripping time independently.

  • The USB flash disk stores 300 processes, which can be imported and exported.
  • Electromagnetic automatic locking of grinding head, replacing manual grinding head locking wrench, which is more convenient.
  • By easily replacing the magnetic anti sticky disc, all processes such as rough and fine grinding, rough and fine polishing of various samples can be completed. One disc is equivalent to several discs.
  • Mobile terminal remote control operation (optional).
