Multiple Spindle Optional CNC Internal Grinder for Short and Longer Workpiece, Internal Grinding Machine

High precision CNC internal grinder-IG200

The grinding wheel spindle adopts an electric spindle with the characteristics of high speed, high precision, high rigidity, low vibration, low noise and low temperature rise. The driving system is cooled by a water cooling system to ensure that the grinding wheel headstock always works in a thermally stable state, making the grinding wheel more stable, and working efficiency is doubled. According to the processing needs, electric spindles with different speeds of 24000-60000rpm are optional; for workpieces with deep inner circles, an integrated spindle can be customized to achieve precision grinding.

An automatic centralized lubrication system lubricates the machine linear guides and ball screws continuously, which makes sure longer service life and high precision. The cooling system is separated with machine body, which eliminates vibration and helps heat radiation.

Siemens 828D CNC system is used.

• Grinding program is created automatically through the user-friendly interface, using graphical programming tools shopmill / shopturn, unnecessarily needing special G codes (Optional).
• No need battery or cooling fan. And no need memory battery for the motor coder.
• Ethernet connector. No capacity limit USB (on line) and CF card. The programs in USB and CF card can be modified at will. Process monitor on line. And the data can be saved forever.
• Process showing with animation. High efficiency.
• There are kinds of optional functions, including automatic end-surface measuring, automatic inner diameter measuring, hydraulic tail stock, highly integrated auto loading and unloading system, and so on.
• Automatic wheel dressing and offset. Keep high precision and stability for the feeding and grinding.

The feed axis adopts a per-loaded high-precision linear guide design, which can withstand loads in all directions, highlights the characteristics of low friction coefficient and eliminates motion gaps, providing a practical guarantee for achieving 0.001mm programming accuracy; high-grade ball screws has excellent protection to accuracy.
