- Some models feature variable speed settings facilitated by the motor and gear system.
- Proper lubrication within the gearbox reduces wear and tear.
2. Spindle and Arbor
The spindle is a central shaft connected to the motor via the gearbox. The arbor, a threaded section of the spindle, is where the grinding wheel or disc is mounted.
Key points:
- The arbor must be compatible with the disc size and type.
- Tightening nuts secure the disc in place.
- Bearings support the spindle, allowing smooth rotation.
3. Grinding Disc or Wheel
This is the functional component used for cutting, grinding, or polishing. Discs come in various types, such as abrasive wheels, diamond blades, or polishing pads.
Key points:
- Disc compatibility with the arbor size.
- Proper installation and secure fastening prevent accidents.
- Regular inspection for cracks or wear is essential.
4. Guard
The guard is a protective cover that surrounds part of the disc to shield the user from sparks, debris, and accidental contact.
Key points:
