In the process of preparing metallographic samples, grinding and polishing of the samples are indispensable procedures. After grinding and polishing, the samples can obtain a mirror-like bright surface. The DRMP-1T metallographic sample grinding and polishing machine adopts a touch screen, allowing the speed of the grinding and polishing disc to be infinitely adjustable between 50 and 1000 r/min. By changing the metallographic sandpaper and polishing cloth, the grinding and polishing procedures of the samples can be completed, demonstrating a wider range of applications. The shell is made of integral vacuum forming, with a novel appearance, featuring stable rotation, low noise, convenient operation, and high working efficiency. It also comes with a built-in cooling device, which can cool the samples during grinding and polishing to prevent damage to the metallographic structure due to overheating of the samples.
Features and Characteristics:
1. The shell is made of ABS in one piece, with a novel appearance.
2. The faucet is made of full copper with chrome plating, providing good corrosion resistance.
3. It has an automatic cleaning function that can clean the dirt collection tray automatically, keeping it clean (optional).
4. It is equipped with a DC brushless motor, which rotates smoothly, has low noise and a long service life (optional).
5. It has stepless speed regulation and eight fixed speeds, which is convenient and fast to meet various needs.
6. It has a countdown function, with the time set arbitrarily, and it will stop when the time is up (optional).
7. The grinding and polishing disc can rotate clockwise or counterclockwise to meet different needs.

Typical application scenarios
1. University/Research Institute Laboratory:
Multiple people share the equipment. The "conventional steel process" and "aluminum alloy soft material process" are solidified on the touch screen. Students only need to select the formula to make qualified samples.
2. Quality Inspection of Auto Parts:
Hundreds of samples are inspected every day. The same process formula is uniformly called up to ensure the comparability of inspection results between batches.
3. Third-party Testing Center:
It is necessary to keep records of the sample preparation parameters for each sample. The touch screen model can directly generate and export the sample preparation record, meeting the requirements of CNAS/ISO and other systems.
4. New Material Research and Development:
It is necessary to frequently adjust the grinding and polishing parameters for process optimization. The touch screen can quickly create and modify formulas, which is much more convenient than changing mechanical gears and taking notes.
Usage and Maintenance Suggestions
1. Process Development Stage:
First, explore suitable parameters using traditional methods, then input them into the touch screen and save as a fixed recipe to avoid long-term "on-site parameter adjustment".
2. Daily Use:
Check the cooling water level and whether the filter screen is clogged at the beginning of each shift.
Regularly inspect the wear of sandpaper/polishing cloth and replace it in a timely manner as prompted by the program.
3. Software and Data:
Regularly back up process recipes and user data.
When upgrading the firmware, pay attention to compatibility with the existing process.
4. Personnel Training:
In addition to basic operations, training should also include: how to select appropriate preset processes or program them independently based on the material and inspection purpose.
