Shanghai Antishicnc Machine Equipment Co., Ltd. is one of the most reliable manufacturers and suppliers of cnc internal grinding machine in China, specialized in providing high quality machines with low price. We warmly welcome you to wholesale durable cnc internal grinding machine for sale here from our factory.
Superior Structure & Micron-Level Accuracy
The cnc internal grinding machine base and critical components are made of FC-30 high-grade cast iron, processed through artificial normalization and natural aging to eliminate internal stress. All structural components are machined in a single setup using world-class equipment from YASDA, MITSUI SEIKI, TOSHIBA, and ELB, ensuring micron-level accuracy and establishing a robust foundation for precision performance.
Intelligent Lubrication & Cooling Design
An automatic lubrication system continuously maintains the machine's guideways and high-precision ball screws, ensuring long service life and consistent accuracy. The cooling system is separated from the machine body, effectively eliminating vibration and enhancing heat dissipation, thereby contributing to overall machining stability.
High-Rigidity Grinding Spindle
The grinding spindle adopts a FAG high-precision bearing sleeve structure, which requires no separate lubrication, simplifies maintenance, and eliminates metal-to-metal contact. This results in high rigidity, high accuracy, and an almost maintenance-free, near-permanent lifespan. For special applications, an optional electric spindle is available to increase the wheel's linear speed for enhanced performance.
Advanced Siemens CNC System
The IG200 cnc internal grinding machine is equipped with the Siemens 828D CNC control system, optimized through secondary development to offer a user-friendly interface. Combined with Siemens high-performance servo motors, it ensures seamless compatibility with the drive system. The control system supports automatic wheel dressing and compensation, maintaining consistent feed and grinding accuracy.
Designed for digital manufacturing, the system ensures stable and repeatable product quality. It features a durable magnesium alloy die-cast panel, IP65-rated protected buttons, permanent data storage without batteries, and interfaces such as Ethernet and USB for online monitoring and program editing. Additional features like animated machining cycles and graphical programming further improve operational efficiency.
High-Precision Feed & Workpiece Systems
The Z-axis adopts a preloaded high-precision linear guideway, capable of withstanding multi-directional loads while maintaining low friction and zero backlash, ensuring true 0.001 mm programming resolution. The high-grade ball screws deliver excellent positional retention and accuracy. The workpiece spindle headstock uses a sleeve-bearing spindle, and the X-axis achieves a maximum travel speed of 10 m/min with 0.001 mm feed resolution. The cnc internal grinding machine can be equipped with film-type chucks, hydraulic 3-jaw chucks, and roller-type wheel dressing devices, fully meeting the diverse demands of high-precision internal grinding.
