Engineering Excellence & Machine Architecture
A detailed overview of the machine’s core components, designed to deliver precision, stability, and high-performance grinding.
Machine Base & Structure
The machine bed is built from one-piece, specially graded close-grain cast iron with a box-type structure and optimized ribbing.
This construction ensures high static rigidity and vibration-free dynamic performance, resulting in superior machining accuracy and long-term stability.
Z-Axis & Taper Grinding Capability
The Z-axis table is designed to swivel, enabling precise taper grinding operations. When combined with a steady rest, the machine can efficiently handle long and heavy components.
This feature makes the IGL Series ideal for extended bore grinding applications.
Wheelhead Assembly
The machine is equipped with a cartridge-type wheel spindle, ensuring stable and high-precision grinding.
The spindle is driven by an induction motor via a flat belt, providing smooth power transmission and consistent performance. An optional high-frequency spindle is available for advanced applications.
Workhead System
The workhead is swivelable, allowing taper grinding and enhancing machining flexibility.
It is designed to provide stable and precise rotation, ensuring consistent grinding quality for long bore components.
Guideways & Axis System
- Z-Axis: V-flat Turcite guideways for smooth and stable movement
- X-Axis: Precision cross roller guideways for high accuracy
Both axes are equipped with precision ball screws, ensuring accurate positioning and repeatability during grinding operations.
Dresser Unit
The machine includes an arm-type dresser, enabling efficient wheel dressing for maintaining grinding accuracy and surface finish.
