Drill Mill Chuck









• Product Introduction

High-accuracy Drill Mill


Yukiwa's drill-mill collets are not interchangeable with ER and ESX spring collets.
Yukiwa's super quality drill-mill collets are the result of more than 40 years of experience and achievement as manufacturer specializing in collet chucks. Even the standard Collets have accuracy (T.I.R.) of half the specified figures under DIN6341.
Strong Gripping Torque
Tapping Collets
YUKIWA's lock nuts have steel balls inserted and have gripping torque approximately two times that of lock
nuts without steel balls. 		YUKIWA's tapping collets are the same shape and size of our drill-mill collets and are interchangeable with each other. The tapping collets feature a "floating mechanism" inside and are suitable for application on machines where spindle rotation is not synchronized with feed-rate.
Dust Protection Lock-nut
Simple and Ensured On-Off of Collet

Lock-nuts with steel-cover for dust -protection are also available at option.
These dust-protection lock-nuts prevent
dust and metal chips from entering the spring collet slits, preventing contamination and damage of the collet and holder.

A crescent-shaped rib is fitted on the inside periphery of the lock-nut.

Place the collet into the lock-nut and tilt the collet slightly so that the crescent shaped rib fits securely into collet's circumferencial notch.

When the lock-nut and collet have been assembled and screwed to the chuck body, insert the tool into collet and tighten lock-nut with Spanner wrench.

• Tapping Collets

How to use

The following programming for tapping process is recommended; fast approach to the work piece, then tapping feed with approxiomately 95% of the pitch value,which uses 20-30% of the compensation stroke(E), when the spindle rotation and feed movement are simultaneously reversed.

Return feed must be made with 100% of the pitch, which maintains the sleeve of tapping collet in compensation stroke up to the tap disengagement; quick return can then be programmed with usual stroke security. The relatively long axial compensation assists easy programming. When tapping with very high speed, an appropriate compensation may be necessary to balance the differences of intertia between the spindle and the feed movement on reverse.

• Drill Mill Chucks for Oil Coolant Drills

Coolant-Sealing Back-up Screw

These back-up screws have a seal made from urethane material, resistable both to water-soluble coolant and to oil coolant, which enables machining without decrease of coolant supplying pressure.

Applicable for oil-coolant drills having more than 5mm diameter hole.

These Coolant Sealing Back-up Screws are capable of sealing for oil-coolant drills having hole diameter 5 to 20mm.

Lock Nuts for Dust  Protection  

The steel cover prevents metal chips from entering into the collet slits and accordingly protects the tapered parts of the collet and the collet holder against damages and prevents deterioration of the run-out accuracy.
The steel cover is press-fitted with its edge being caulked and therefore not detachable during use. Also it is durable against hot-burned metal chips.

Methods for use:

1.On the center of the lock-nut, an opening of 0.12"dia. is made.

2. This opening must be widened by a drilling machine to 0.01" to 0.012" larger than the outside diameter of the tool shank to be used.

3. Mounting of the lock-nut to a drill-mill chuck must be done after metal chips have completely been removed from chuck.
