CNC Controller

i-Grind Graphic Conversational Interface - Features an intuitive graphical user interface with conversational programming capabilities, including advanced functions for automatic dressing and compensation to ensure optimal grinding wheel performance and extended tool life.

Internal/External Straightness Offset Function - Equipped with sophisticated offset functionality that compensates for both internal and external straightness deviations, ensuring superior dimensional accuracy across all machining operations.

High-Resolution Axis Control - X & Z axis movement with an exceptional 0.0001mm (0.1 micron) minimum resolution, providing ultra-precise positioning capability for the most demanding grinding applications.

Data Management System - Comprehensive data upload and storage function for long-term usage, allowing operators to save, retrieve, and manage grinding programs efficiently for repeat production runs.

Immediate Dressing Function - Quick-access dressing capability designed to minimize machine setup time and maintain optimal grinding wheel condition, reducing downtime between operations.

Intelligent Current Monitoring - Advanced current indicator that not only integrates with crash control function for machine protection, but also continuously monitors load changes during operation, automatically reducing machine setup time and preventing potential damage.

MPG Program Simulation - Ability to simulate and verify grinding programs with Manual Pulse Generator (MPG) before cycle start, ensuring error-free operation and preventing costly mistakes.

Large-Format Operation Panel - Expansive operation panel featuring a 10.4" high-resolution screen, complete with comprehensive grinding cycle programming options including rough, medium, and fine grinding values, significantly increasing operational efficiency and flexibility while maintaining ease of use.
