PAK1837.250
Chucks with 4 fixed jaws with jaws B=250 steel, Components: steel hardened part
Estimated delivery: On request
Plates with 4 fixed jaws are particularly suitable for central clamping
of parts on drilling and milling machines. Thanks to the arrangement of the jaws in the versions
hard and soft, parts of different sizes and shapes can be easily clamped by the
inner or outer side.
Material:
Steel.
Version:
Contact surface of the main body ground.
Hardened and ground jaws.
Order example:
K1837.250
Note:
Observe the numbering when fitting the jaws.
The jaws are precision ground. The tolerances W, X, Y, Z between each other are within the dimension of 0,05 mm.
The repeatability value for centric clamping with hard jaws is 0,02 mm.
The movable base jaws are actuated via the rotating ring located in the plate.
Thanks to the rotary movement of the threaded spindle, the large crown gear transmits the force to the base jaws, producing a synchronous movement inwards or outwards.
Lack of lubrication causes excessive wear and a reduction in clamping force. Note the regular lubrication intervals.
Advantages:
The repeatability with central clamping is 0,02 mm.
Flat design.
For drilling and milling machines.
Main body precision ground.
Excellent accessibility of the lubrication system.
Large through hole for fastening bars.
Operation with a hex key, therefore quick and simple operation.
Soft jaws can also be screwed onto the basic jaws.
Scope of delivery:
Clamping wrench.
Accessories:
K1838 Steel jaws, soft
Drawing note:
1) Reversible jaws
2) Basic jaws
3) Clamping screws
