1. Suitable for single-sided flat processing technology of various materials, mainly used for high-end products such as sapphire and silicon wafers
2. High requirements for flatness and production capacity, as well as the need for forward and reverse machining processes
characteristic:
1. The spindle motor and four grinding heads are all controlled by frequency conversion, providing real-time and effective protection for the motor with soft start, soft stop, and no impact.
2. The four workstations use independently developed cylinders that can work together or separately. Each workstation can choose to increase/decrease pressure separately, and the pressure of a single workstation can reach 220KG or more
3. All positions in contact with the liquid are made of stainless steel material
4. Equipped with automatic stirring and automatic dripping devices to reduce grinding fluid waste and save processing costs
5. The operating system adopts a fully independently developed electronic digital interface with stable performance, touch screen operation, and visual parameter settings
6. Four grinding heads with built-in weights, each with an independent driving device and the ability to set the speed and direction separately, reducing the trouble of different grinding head speeds and improving the consistency of workpiece accuracy at each workstation
7. Adopting precision pneumatic components imported from Japan for real-time detection of air pressure, effectively improving the phenomenon of product defects caused by unstable air pressure
8. The body adopts all stainless steel sheet metal edging for a more beautiful appearance
9. Processing parameters can be set in segments to meet the required pressure and speed of the workpiece in each process
10. The grinding disc base is made of stainless steel material
