Main features:
1. Specially designed and manufactured for tungsten carbide roller ring grinding
● Highly targeted use, designed and professionally produced with a strong grinding mechanism.
● Compared with the machine tool transformed from an ordinary grinder, it is more professional, has better rigidity, and has a stronger adaptability to the processing range.
2. The CNC system has stable quality and reliable performance
● Adopting the German SINUMERIK 808D ADVANCE industrial CNC system and Siemens' three-axis AC servo motor drive system, the performance is stable and reliable.
● The equipment is equipped with a mobile operation electronic handwheel, and the manual mode displacement control is more convenient and accurate.
3. Built-in operating program parameterized control, intuitive operation, strong logic, and high degree of automation.
● The system is equipped with a special roller ring processing program. According to the requirements of the roller ring, the processing mode is directly selected to realize the machine tool's automatic processing of the outer circle and hole groove of the tungsten carbide roller ring. It is logical.
● The program automatically memorizes the grinding wheel position during processing. The parameters are fully explained in Chinese. It can accurately complete the full CNC processing of the outer circle, single groove and double groove of the roller ring. Simple operation. No need for multiple tool alignment.
4. Good machine rigidity and high grinding efficiency
● All parts of the machine tool are designed as integral castings, with a net weight of 4.5 tons.
● The sliding closed guide rail can be used for large cutting depth grinding, effectively suppressing grinding vibration and ensuring high-efficiency and high-quality processing.
5. High spindle precision, good precision retention and long service life
● The spindle support adopts imported SKF or FAG double-row short cylindrical roller bearings.
● The spindle seal adopts a new gap-type labyrinth seal structure to effectively protect the journal from wear.
● The spindle drive adopts a load-unloading belt pulley structure to effectively improve the spindle's precision retention and the service life of the spindle and bearings.
6. The advantages of the steel self-centering roller ring clamp are obvious
● The roller ring clamp structure realizes one-button clamping. The clamping is convenient and reliable, and the hydraulic clamping saves time and effort.
● The roller ring clamp adopts a steel self-centering elastic expansion sleeve with large expansion volume and long service life.
● The clamping method of loading and unloading the roller ring facilitates the future upgrade of functions such as automatic upper and lower roller rings.
VII. Fully enclosed cover design
● Effectively reduce processing noise and provide safer protection.
● Prevent the diffusion of water vapor in the processing area and improve the processing environment.
