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.
