1.Product Overview
HMP-2AB set pre-grinding, grinding, polishing in one of the double disc automatic grinding and polishing machine. It adopts single-chip microcomputer technology through touch screen control, grinding disc is driven by DC brushless motor, V belt for transmission, grinding head is driven by stepper motor, synchronous belt for transmission with smooth rotation, low noise, long life and other characteristics; According to the needs of users to adjust the grinding head and grinding disc speed, set their own pressure, set their own sample preparation time, to adapt to different needs; With lighting system, easy to take and place the sample; It comes with cooling device, which can cool the sample during grinding to prevent the metallographic structure from being destroyed due to overheating of the sample. It is an ideal choice for metallographic sample making equipment in factories, scientific research institutions and universities.
2.Main functions and features
1. The base is made of aluminum alloy casting, light weight and good shock absorption ability, anti-corrosion.
2. The shell adopts ABS blister integrated molding, with novel appearance and anti-corrosion.
3. Faucet adopts all copper chrome plating process, good corrosion resistance.
4. Touch screen control and display, easy to operate, clear and intuitive.
5. One-key automatic start function, after the sample is put into the clamping plate, click to start, the indenter will automatically press down, the grinding head will automatically run, the faucet will automatically water, and the faucet will automatically close after the grinding is completed.
6. It has the function of fixed speed and pressure.
7. Built-in nozzle collection tank for automatic cleaning.
8. Support stepless speed regulation or four speed regulation mode, speed regulation is more convenient.
9. The grinding head is automatically locked by electromagnetic clutch, which is convenient and fast.
10. Support the single motion and linkage start of the mill throwing disc and the mill throwing head, and the use is more flexible
11. Can store more than 100 groups of grinding and polishing process parameters, easy to call quickly.
12. Magnetic disc design, support quick disc change, change sandpaper and polishing fabric more quickly.
13. Sample chuck automatically relax and tighten, with the inside lighting system, easy to take and place the sample.
14. Equipped with quick sample gripper plates, which can be replaced at any time with different diameters.
15. The whole machine adopts DC brushless and stepper motor, stable rotation, low noise, long life.
16. Double pressure mode, center pressure and single point pressure two, more powerful
17. Dual disk dual control use is more flexible.
18. The emergency stop button makes it easy and quick to stop the operation immediately.
