Note 1) The gripping accuracy is the Total Indicator Reading of a test bar right after forming jaws to grip a test bar.
Note 2) The repeatability is the Total Indicator Reading of a test bar measured by detaching the formed jaws from the chuck and mounting them again in the same position.
Note 3) Both gripping accuracy and repeatability are the T.I.R. of a test bar at 10 mm above from Kitagawa standard soft jaw.
All the above criteria are based on our internal regulations.
