DURO-key bar chucks and plane spiral chucks (DIN 6350 und DIN 6351) are successfully used wherever extremely high tension forces, high concentric accuracy and reliable continuous repeatability are needed. The three-jaw DURO key bar chuck is characterised by its very high tension force and accuracy, which is twice a high as prescribed in DIN 6386. The running and run-out accuracy of our three- and four-jawed plane spiral chucks meets DIN 6386, Part 1, Accuracy Class I. In order to machine large and heavy workpieces at the highest possible cutting capacity, optimum clamping is required using great forces. Röhm plane disks, with a diameter of up to 4500 mm and their indisputable merits have proven themselves here.

VC Quick change Jaw system VC
The quick change jaw system VC is as simple in handling as effective in reduction of the set-up time. In spite of the same repeatability and less space requirement - compared to general mounting systems - very high clamping forces are permitted as well. Therefore, this quick change jaw system in connection with a high-quality chuck represents an economic problem solution to improve productivity.
Advantages at a glance:
- Jaw change within seconds
- For I.D. and O.D. clamping
- Jaw change system easily to be realised automatically
- Best repeatability

F-Tool PIN center chuck
The PIN center chuck is a compact reference system and is able for the collet of electrodes and work pieces. It‘s also the base of the F-Tool PIN ZeroPoint centering system. The centering, respective the positioning happens in two steps. The first step is the pre-centering with the PIN centering bolt. The precise centering is done, if the cone of the spigot is intervening on the flexible centering plate, and the piece is drawn to the clamping area. With the intervention of the PIN index 8 mm into the cross slot, the angle coat is defined.

NC-Drill ChuckF
1. It is available in capacity of 1 to 13 mm / 3 to 16 mm, with BT shank (MAS 403); SK shank (DIN-69871), and HSK63 shank (DIN 69893).
2. The integral shank makes this chuck more suited to CNC machine applications because overall length is shorter than that of normal keyless drill chuck mounted with an arbor.
3. The Integral shank provides greater accuracy and eliminates the possibility of the chuck slipping on an arbor.
4. Balanced.

ITW Workholding offers a wide range of power chucks for special design applications. Products include:
Woodworth UBL (shown) - This is a ball chuck with offers pull down gripping. Available in centering and / or compesation style. The UBL provides 6 points of contact (3-jaw model) using jaws that conform to part differences
Woodworth ECC - This 6-jaw equalizing, counter centrifugal, chuck is used in applications where part tolerances are very tight. Where most chucks offer a 3 to 1 grip force ratio, the ECC offers a 2 to 1. This means you can have finer adjustments for grip force. Also, the standard feature of the counter centrifugal force compensation means you can run at higher speeds with less grip force loss.
Collet Chucks - Used in 2nd operation turning, ITW Workholding designs and builds special collet chucks which offer a wide range of solutions to your turning, milling or grinding requirements.

Hardinge FlexC™ Collet Systems are flexible, sealed collet heads that interchange in seconds and are available with spindle mounts for all brands of CNC lathes.
Pull-back thru-hole, pull-back stationary stop and push-to-close dead-length® styles are available for main and sub-spindle CNC lathe applications. Hardinge FlexC collet heads are fully interchangeable with competitor’s models. Hardinge guarantees accuracy within .0004" (.010mm) TIR for the collet system models A and D, and .0008" (.020mm) TIR for style DL.
The changeover concept is simple using a manual wrench to compress the collet for quick removal or replacement in seconds. A typical FlexC collet head has a gripping range of .020" (.5mm) above and below its nominal size to allow variation in bar stock without having to change the collet. Parallel clamping minimizes stock "push back" and requires less draw bar force to achieve the same gripping capability as conventional collets.
Emergency collets are reusable. Standard hardened and ground collets are stocked in round smooth, round serrated and hex shape. Square sizes are made to order. Special applications including stepped holes, special shapes, off-center, etc. can be custom-made from stock blanks.

Modern machines and tools have greater demands on tool holders. Particulary if cemented carbide endmills and drills are used at very high speed, where a very low run-out is required to achieve long toollife.
CoroGrip® and HydroGrip® fulfil all the demands on a tool holder for HSM.
Three requirements have to be fulfilled when using holders with cemented carbide endmills or drills at high speed:
-Low run-out
-High clamping force
-Balanced holder
Every CoroGrip and HydroGrip chuck is individually balanced and they have an individual number and is delivered with a protocol.
