Workrest Blades
Work rest blade is a critical component used in centerless grinding.
Call us for your tailored solutions that best suit your requirements.
Work rest blades:
- Supports the workpiece from below, ensuring it stays in the correct position.
- Maintains height and angle of the workpiece relative to the wheels, which is crucial for dimensional accuracy.
- Prevents deflection or movement, helping achieve a uniform surface finish.
- Controls contact point between the workpiece and wheels, influencing grinding precision.
Types of Work Rest Blades
- Through-feed blades: Used for continuous grinding of straight cylindrical parts.
- Plunge-cut (in-feed) blades: Used for parts with complex shapes or varying diameters.
- Stepped blades: Designed for grinding parts with multiple diameters.
- Prism blades: Feature a prismatic guide for clean feeding and removal of parts.
Applications
- Automotive components (e.g., camshafts, piston pins)
- Bearing industry (e.g., rollers, rings)
- Textile machinery (e.g., needles)
- Precision tools and small parts manufacturing
The quality and setup of the work rest blade directly affect the accuracy, surface finish, and efficiency of the grinding process.
