Description:
Locating cylinder stainless steel Ball Lock for mechanical locating and clamping system.

Material:
Locating cylinder and ball: stainless steel 1.4542.

Version:
Locating cylinder and ball hardened to minimum 40 HRC, bright.

Function / Application:
- Tightening the thrust screw presses the centre ball downwards and forces the three locking balls outwards into the receiver bush.
- Designed for rapid, precise positioning and clamping; catalogue states machine setup times can be up to twelve times shorter than conventional methods.

- Grid plate thickness: 40 mm.
- D: 35 mm.
- D1: 60 mm.
- D2: M12.
- L: 71 mm.
- L1: 13 mm.
- SW: 6 mm.
- Holding force F: 68 kN.
- Maximum tightening torque: 33 Nm.
- Repair kit order no.: K1474.935040.

System Information:
- Mechanical locating and clamping system enables base and tooling plates to be precisely positioned and fastened in a few seconds.
- System consists of a locating cylinder, centring bush and receiver bush.
- Recommended sequence: mount two receiver bushes on the machine table/base plate and two centring bushes on the clamping plate; insert locating cylinders through the centring bushes into the receiver bushes; turn the set screws in the locating cylinders approximately two rotations to clamp.
- A grade I centring bush and a grade I or grade II centring bush should be installed as far apart as possible in each fastening plate; more than two positioning points do not improve positioning accuracy.
- When more than two locating cylinders are used for additional holding force, the additional holes in the fastening plate should be 0.4-0.8 mm larger than the selected locating-cylinder diameter.
- With centre distance tolerance +/-0.005 mm and two grade I centring bushes, repeat accuracy within +/-0.013 mm can be achieved.
- With centre distance tolerance +/-0.03 mm and one grade I plus one grade II centring bush, repeat accuracy within +/-0.04 mm can be achieved.
- Grade II centring bushes have a larger internal diameter to accommodate the larger centre-distance tolerance.
