Kitagawa High Precision, Ultra-large Through-Hole, BR Series Power Chucks
The standard has evolved.
- Gripping accuracy of 0.01 mm T.I.R. or less Note 4
- Reduced jaw-lift
- Interchangeable with Kitagawa B-200 and BB200 series
- With Tnut-Plus optional dedicated T-nuts, the repeatability of jaws at detaching and attaching is 0.01 mm T.I.R. or less Note 4
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.
Note 4) Both accuracies for only BR12 are 0.015 mm T.I.R.
Note) The 3D data includes two types of the positions of the jaws for both Parasolid and STEP: open end (UC) and closed end (OC).
