Introduction of the auto lapping and polishing machine:
The UNIPOL-1260D Double-Plate Pressure Grinding and Polishing Machine adopts a mechanical pressurization method, allowing the sample to be subjected to constant pressure during the grinding process. The machine is equipped with two sets of pressure grinding plates that can move horizontally, and the rotation speed is stable and adjustable. With a wide pneumatic pressure range, it is particularly suitable for grinding, thinning, and polishing sheet-type superhard materials.
Main Features
· The sample is fixed on a dedicated sample holder, which can be easily installed using a quick-change chuck. An elastic coupling is incorporated in the holder base to prevent impact damage when the sample first contacts the grinding/polishing plate.
· When the sample comes into contact with the grinding/polishing plate, the pneumatic cylinder arm begins to apply pressure. The pressure can be preset and, due to stepless adjustment, can also be adjusted at any time during operation. The maximum pressure can reach up to 0.48 MPa.
· The rotation speeds of both the grinding/polishing plate and the sample holder can be steplessly adjusted within a certain range, allowing for both presetting and real-time adjustment.
· The grinding and polishing time can be freely set within a range of 0–24 hours, enabling automatic operation and auto stop for unattended processing.
· Core components are precision-machined from stainless steel, offering excellent corrosion resistance and preventing rust.
· All pneumatic and electrical components are selected from mature and reliable high-quality products, ensuring stable performance, high reliability, and long service life.
·The frame is constructed from high-quality welded steel, providing high strength, good rigidity, and durable performance.
· Equipped with two sets of sample holders capable of lateral oscillation, ensuring stable operation, high processing efficiency, and excellent sample quality.
· Particularly suitable for the grinding and polishing of superhard materials.

Advantages of the Professional-Grade Pressure Grinding and Polishing Machine:
1. Constant Pressure System:
This machine employs an advanced mechanical pressurization mechanism to ensure that the sample is subjected to uniform and constant pressure throughout the entire grinding cycle, thereby preventing surface damage or thickness irregularities caused by pressure fluctuations.
2. High-Efficiency Dual-Station Operation:
Equipped with two sets of horizontally movable grinding discs and mechanical swing arms, the machine supports simultaneous multi-station operation, significantly boosting processing efficiency for both laboratory research and small-batch production environments.
3. Precise Speed Control:
The sample carrier (10–60 rpm) and the grinding disc (20–250 rpm) feature independent speed control, accommodating a wide spectrum of processing requirements—ranging from coarse grinding to mirror-finish polishing.
4. Broad Application Compatibility:
This machine is particularly well-suited for processing thin, high-hardness sheet materials (such as silicon carbide, gallium nitride, ruby, etc.).
Applications of auto lapping and polishing machine:
1. Semiconductor Processing:
Precision planarization (CMP) of silicon wafers and compound semiconductor substrates.
2. Optical Engineering:
Precision grinding of high-precision lenses, optical filters, and sapphire windows.
3. Materials Research:
Sample preparation for microstructure observation of metal specimens, advanced ceramics, and composite materials.
FAQ of auto lapping and polishing machine:
Q: What sample sizes is the UNIPOL-1260D double disc polisher and grinder suitable for processing?
A: Equipped with Ø320mm grinding discs and compatible with Ø100mm or Ø110mm sample carriers, this double disc polisher and grinder is ideally suited for processing 4-inch wafers (or smaller) or for the batch processing of multiple small samples.
Q: What is the difference between mechanical pressure and pneumatic pressure?
A: The UNIPOL-1260D combines the advantages of both: its mechanical structure ensures stability, while the pneumatic system provides flexible pressure adjustment ranging from 30 to 250 N—making it suitable for processing precision materials that are sensitive to pressure.
