Saw Calibration Machine

One of the final steps in the production of a hand-held circular saw is the attachment and adjustment of the shoe, or bottom plate. This semi-automatic machine was built to calibrate the angle of the shoe after its attachment, ensuring perpendicularity with the saw blade. First the operator threads an extension rod onto the blade arbor, and then the saw assembly is placed in the machine such that the extension rod engages two spring-loaded contact heads. After the operator engages the calibration cycle, the machine automatically adjusts the shoe-position setscrew while monitoring feedback from the contact heads. The machine makes iterative position corrections until the shoe/arbor angle is parallel within a specified tolerance.

Key Features:

  • Robust hardened support nests & pneumatic clamp tools
  • Redundant failsafe operator safety system
  • Dual precision analog inductive sensors yield 0.1 degree accuracy
  • Real-time shoe-angle monitoring and converted data display
  • Intuitive operator procedures for tolerance setup and calibration
