An Inner Circle Grinding Machine is a specialized grinding tool used for precision machining of circular or cylindrical components, particularly those with inner diameters (IDs). It is commonly employed in industries like aerospace, automotive, and tool manufacturing where high accuracy and surface finish are critical.
Key Features & Applications:
1. Precision Grinding – Achieves tight tolerances (µm-level) for inner diameters, concentricity, and roundness.
2. Workpiece Types – Used for grinding:
– Bearing races
– Hydraulic/pneumatic cylinders
– Engine components (e.g., valve seats)
– Dies and molds
– Gear bores
3. Grinding Methods:
– Plunge Grinding: The grinding wheel moves radially into the workpiece.
– Orbital/Planetary Grinding: The workpiece remains stationary while the grinding wheel rotates inside it.
– Traverse Grinding: The wheel moves axially along the bore.
4. Machine Components:
– High-rigidity spindle for stability
– CNC controls for automated precision
– Coolant systems to prevent overheating
– In-process gauging for real-time measurements
