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.

Increased productivity
need not mean heavy investments in new machines.
3Refix is remarkably simple way to lay a solid foundation from which to view the future with confidence – tool up without indication and cut your production costs!
3Refix technology is based on a modular hole pattern with 100x100 mm pitch and 20 mm diameter reference holes. The reference tables have clearly-marked reference holes – A1, A2, B1, B2 etc – and every accessory has two 20 mm diameter holes, which pick up the references from the table. The R0-hole gives the X/Y-position and the R1-hole gives the angle relative to the axes of the machine. This makes it possible to set up the workpiece without the need for alignment and gauging afterwards. So 3Refix accessories provide an unmistakable and fixed position with known references.
The accessories in the 3Refix range usually have a reference height of 30 mm, among other things to allow machining straight through the workpiece. The design also allows a flush pot to be pushed in under the workpiece during EDM machining.
The full effect of 3Refix technology is attained by consistent application with general systemization and standardization of all machine tables and accessories. System 3R can supply reference tables for practically all types and sizes of machines – reference tables that give a distinct interface between machine table and auxiliary tool.

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.

Floating Holder with radially parallel floating feature for reaming on special purpose machines, transfer lines and NC-machines.
: Ø2-Ø20mm
|
|
The MAPAL WELLACH floating holders were designed to allow high speed reamers to be used to their full extent. Radial and angular alignment is precisely defined and preset.
This produces a reliable function even at high feed rates.
This then reduces costs, the results fo the batch remain constant and scrap and reworking kept to a minimum. Because of the narrow design and small diameter of the head, the clearance distance for multi-spindle use is reduced. Because no parts are worn, there is no need to keep cost-intensive stocks of spares.
