Tap Holder – หัวจับดอกต๊าป

Double Roller Clutch Mechanism of Outstanding Endurance & Torque Control Performance

Roller Clutch Mechanism

The conventional ball clutch mechanisms will make a frictional contact of the steel ball to the clutch, which will cause abrasion to the clutch and make the torque readjustment to be necessary after 10,000 or 20,000 times of clutching. On the other hand YUKIWA’s double roller clutch mechanism will not need readjustment even after 250,000 times of clutching.

Computer-calculated perfect spring arrangement

Since the torque setting spring is ideally designed by computer to match with the size of the tap, it will withstand a long time of usage without fatigue.

Quick change system

The one-touch changing of the tap and the collet as well will improve the work efficiency.

Built-in axial float mechanism

The pitch error between the tap threads and the feeding is compensated by the built-in axial float mechanism (tension/compression mechanism), which will assure a precise tapping.

How to set and release the tap collet

【Setting】
1:When the tap collet is pushed into the holder, the cover with a knurled ring will protrude and lock the collet. At this time, the pin-hole must be aligned with the F-mark.
2:Turn the knurl ringed cover to left until the pin-hole to align with the L-mark. This is the double-locked position.

【Releasing】
1:Push the cover with a knurled ring toward the holder side about 2mm and turn it to right until the pin-hole is aligned with F-mark.
2:Push the cover again, then the tap collet will be detached.

Tap Holders with BT Shank

Dimensions of the tapered shank are in accordance with MAS4003-1982 BT Tapered Shank.
The retention knob is not included in the above. They are separate accessories.

Tap Holders with MT Shank

Floating Tap Chucks

 

Quick Change

Attaching of the tap to the tap collet or the tap collet to the holder can be done quickly by one-touch operation, which will eventually improve the work efficiency.

Built-in radial paralleled floating device

The built-in radial float mechanism compensates the centering deviation, if any, between the spindle and the workpiece, which will eventually secure the precise tapping work.
