In summary, a surface grinder is a widely used precision machining equipment that can be used for precision grinding of various workpieces, providing effective processing methods and technical support for various fields in the mechanical processing industry.
Main Components
Ball screw
The screw rods used in the grinding machine are all P3 level high-precision ball screw rods with low rolling friction coefficient and high transmission efficiency, with an efficiency of over 90% and a friction coefficient of 0.002~0.005; Effectively reducing the difference between friction coefficient and speed, the starting torque is close to the operating torque, so the work is stable without impact, with low wear and long service life. The tightening force can be adjusted by the adjustment device, and the transmission accuracy and stiffness are improved; It has reversible transmission, which can convert rotary motion into linear motion and linear motion into rotary motion, effectively improving the working accuracy and stability of machine tools.

Castings(H250)
All castings of the main base and worktable of the machine is made of HT250 high-grade gray cast iron, and through finite element analysis and calculation, they meet the engineering requirements of improving rigidity and quality. Each casting undergoes high-temperature tempering and natural aging for more than 6 months to eliminate internal stress (the casting is heated in the furnace to 550-570 ° C, kept warm for 5-6 hours, and then dropped from 50 ° C to below 100 ° C per hour). The machine body is stable and does not deform, And it has good resistance to bending and torsional stress, ensuring the long-lasting working accuracy of the flat field grinder.

Manual Scraping
The grinding machine adopts a hard rail fully manual scraping and grinding process, and the employees on the position have more than 10 years of work experience. The precision benchmark of the scraping parts is controlled within the range of 10-12 points per square centimeter. The guide rail surface is adhered to imported high-quality PTFE to increase wear resistance and reduce damping coefficient, which can provide support for the operation of the machine tool to ensure sufficient grinding accuracy.

electromagnetic chuck
The electromagnetic suction cup base of the grinding machine adopts steel plate milling chamber technology and all copper coils. Compared with the cast steel base, it has a smaller volume, strong magnetic force, and a maximum of 16kg/cm2. The magnetic force distribution is uniform and adjustable, suitable for various powerful machining and precision machining; It can work continuously for more than 20 hours without any faults every day, with automatic auxiliary positioning function. The workpiece can be clamped or released in 0.3 seconds, greatly improving production efficiency.
