Features
The latest patented high-precision four-corner equal-position pressure regulation technology and the proven high-precision pressure control system can achieve high-precision and high-repeatability position and pressure control.
Users can set and name up to 50 polishing programs, with multiple user authority control methods.
Self-set slow start and slow pressurization time to achieve refined process settings and reduce/avoid fiber collision during polishing.
The pressurization process is uniform and stable, and the speed and pressure are controlled by program closed loop with high precision.
Meet the latest production needs of MMC, SN/MT and other related products.
Combined with Bulls' latest patented technology fixture, it can significantly improve Polishing quality and efficiency while reducing the impact of human factors.
