Base jaws
for your jaw quick-change chucks
At SCHUNK, you will find the largest offering of base jaws for all lathe chuck types. In addition to the jaw interface with tongue and groove, SCHUNK also offers hardened, precision ground base jaws for the use of fine-serrated top jaws. If seamless clamping is not possible with your jaw quick-change chuck equipped with claw jaws, such clamping gaps can be covered, for example, with base jaws featuring ½-tooth offset.
The delivery unit comprises 1 set = 3 pieces , including cylindrical screws. With the exception of base jaws EWB-MT, which are supplied without cylindrical screws.
Tongue and groove and the ground bearing surface are ground. They ensure high dimensional accuracy and fast and simple handling. A ground serration ensures high precision and surface quality of the base jaws as well as an increased service life. Exchanging a clamping unit consisting of base and top jaw in the stationary chuck reduces set-up times.
