1.Product Overview
HMP-2A 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 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, 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 disc, 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. With adjustable timing fixed speed and fixed pressure function
7. Built-in nozzle collection tank automatic cleaning
8. Support stepless speed regulation or four speed regulation mode, speed regulation is more convenient
9. Support single action and linkage start, use more flexible
10. More than 100 groups of grinding and polishing process parameters can be stored, which is easy to quickly call
11. Magnetic disc design, support for quick disc change, change sandpaper and polishing fabric more quickly
12. The specimen clamping disc is automatically relaxed and tightened, and with the inner lighting system, it is convenient to take and place the specimen
13. Equipped with a quick specimen clamping tray, can be replaced at any time with different diameters of the clamping tray
14. Double disk double control use is more flexible, so that the sample preparation efficiency is more efficient.
15. The whole machine adopts DC brushless and stepper motor, stable rotation, low noise, long life
16. Emergency stop button can be convenient and quick to stop the operation immediately
17. Double disk design, sample production efficiency is more efficient
