TOOL AND MATERIAL CLAMPING SYSTEMS
Description of tool holders and tool carriers
Tool holders are mainly clamps and expandable dollies and also derivatives of clamps.
Tool-carrier ranges are manufactured to meet ISO and HSK standards as well as Schaublin’s standards which have often become the standards for the world. We also produce cylindrical tool-carriers, Morse tapers and specific adaptations of particular machines or applications.
Schaublin also develops, on request, special applications that require clamping abilities tailored to the customer’s requirements.
Operation and uses
Clamps are used to grip the material, parts in rotation and counter-rotation or tool shanks. These clamps are of pull or thrust type where the force on the taper closes the clamp onto the part to be gripped.
Clamps are generally steel, sometimes brass or with inserts of other materials.

Multisize Collets For KC, PC And DC Chucks
Each multisize collet has a gripping range of 3.2mm enabling metric or imperial sizes to be gripped in the same collet. Six full length blades give positive and parallel grip on round or hexagonal bar. Collets may be fitted with end stops or ejectors for short components. Serrated blade collets are available for use on black bar for applications which require extra grip. Serrated collets are for use in power chucks only.
Range 1.6mm to 63.5mm

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.

HSK Tooling Types Offered:
• Four types of MEGA Chuck series optimises high speed and precise cutting with drills and endmills.
• The Fullcut Mill, the world's first indexable insert endmill, offers both accuracy and toughness.
• KAB tool shanks, the original and #1 modular boring system in the world!
Premium Material Selection
Since HSK is a hollow taper shank, the material has a critical role for optimum performance. BIG uses carefully selected high grade alloy steels. Particularly, BIG uses die steel materials for HSK 40 and smaller where the cross section of shank taper is very thin.
Important Tool Retention Feature
Internal clamping of HSK tools is defined by the location of highly concentrated forces from the machine tool. Accuracy and position of this form will affect the righdity, repeatability, and precision of tool holders. BIG provides finish machining of this area after heat treatment.
Drive Key Form
HSK Shanks according to Form A are designed to carry out torque transmission by the round shaped key-way at the end of the taper. Because of the importance of this round shaped geometry, BIG provides finishing of this feature after heat treatment.
Pre-Balanced Design
Since HSK Form A has non-symmetric keyways, it is not balanced. BIG Form A holders are pre-balanced near the tool change V-Groove recommended by ISO standard and can therefore be used for high speed applications.
Hole For Manual Clamping
BIG HSK Form A holders have a manual clamping hole as a standard and can therefore be used in place of HSK Form C which is manually mounted in spindles.

- Every collet chuck comes with our exclusive "Power Coat" nut that holds up to 75% tighter than standard nuts. (greater holding force improves T.I.R., rigidity, and reduces tool slippage to extend collet life)
- Tolerance measured from taper O.D. to collet pocket I.D. is only 0.0001" (our competitors average 0.0002")
- Every collet chuck is lab tested and delivered with a full report documenting T.I.R., balance, taper, etc.
- Our standard precision collets feature T.I.R. of only 0.0004" (our competitors average 0.0006" - you gain 20% tool life)
- Each holder is factory balanced to 18,000 RPM @ G2.5 (great balance reduces vibration at all RPM's - saving toolife, spindle bearings, and improves surface finish)
- Each taper is precision ground to a tolerance of AT3 or better!
- All products are backed by our 100% satisfaction guarantee.
Advantages:
- Flexibility (fits a wide range of tool shanks)
- Accurate (when maintained to specifications)
- Fast and easy tool changes

To achieve best results with centerdrill we recommend the following basic equipment:
1x collet chuck with cooling ring, clamping nut and spanners.
1x centerdrill collet, optional Ø 6, Ø 8, ..., Ø 20mm
1x 250 gr. parting paste for flow punch forming
1x 0,5 l lubricant for thread forming
Due to the extreme thermal fluctuation and the radial load, proper clamping of the workpart and the flow punch former is critical. The warmth generated during the process must not be allowed to enter the spindle but instead must be deflected or cooled. Customary three-part chucks can cause breakage of the flow punch former if it is not clamped centrally!
For this reason a collet chuck with cooling ring was developed especially for flow punch forming with centerdrill, with which the heat can be dissipated ideally and a secure clamping can be ensured. For optimal concentricity and secure clamping, a special collet is used to locate the centerdrill.
Parting Paste
Moistening the centerdrill with our highly heat-resistant parting paste, matched to the respective material to be processed, is important for the service life of the centerdrill. The paste can be applied manually or with a spray device.
Lubrication during thread forming
The use of our lubricant is highly recommended during thread forming. It should be applied before each operation on the center- tap. Our lubricant is ecologically tested according to DIN.

– Also for standard collets ER according to ISO 15488 (formerly DIN 6499)
– High rigidity
– Smoother running thanks to vibration absorbing geometry, therefore better surface quality and protection of tools, spindles and machines
– Increased machining capacity due to higher spindle speed, higher feed and larger cutting depth
– Shorter processing times
– Higher machining accuracy
– High clamping force
– Equally suited to high-speed manufacturing and heavy milling

EXPANDING MANDRELS AND COLLET CHUCKS
Expanding mandrels are the ideal solution to many workholding problems. By holding parts on most of the datum bore (or outside diameter in the case of a collet chuck) the clamping forces are evenly distributed, reducing distortions during part manufacture.
Mandrels also provide a superior method of holding parts which are high volume, have short cycle times or require the highest levels of concentricity.
Chevin manufacture expanding mandrels tailored to your exact specifications. Many different mounting styles are available, including: spindle nose, between centers, Morse taper and faceplate. Different actuation methods can be used, such as drawbar, cantilever nut and front nut.
Every expanding mandrel or collet chuck supplied by Chevin can have the following features:
* Single taper sleeves
* Positive clamping and release
* High levels of concentricity – to 0.0002" T.I.R
* Controlled datums
* Sleeve interchangeability
* Generous expansion capacities
All of the above permit quick and secure clamping creating versatility and ease of use.
