1. What is a CNC Grinding Lathe?  
A CNC grinding lathe integrates grinding and turning operations into a single automated system. Unlike conventional lathes, which primarily perform cutting, drilling, or threading, this machine uses abrasive wheels to achieve micron-level precision on hardened materials like steel, ceramics, or composites. The CNC system ensures repeatability by following programmed instructions, eliminating human error.  

Key Components:  
- Grinding Wheel: Made of diamond, CBN (cubic boron nitride), or aluminum oxide for material-specific grinding.  
- CNC Controller: Converts CAD/CAM designs into precise movements.  
- Workpiece Spindle: Rotates the part during grinding/turning.  
- Coolant System: Prevents overheating and maintains surface integrity.
