The machinging zero point is defined
by the centre of the chuck in the GPS 240 system. The chuck can be mounted on the machine table of any machine tool.
The standardised hole pattern allows clamping from below of workpieces, fixtures and accessories such as vices, three-jaw chucks and magnetic tables. This gives collision-free mounting, even with five-sided machining.
The economical, pressure-die-cast aluminium pallets are very light, making them especially suitable for manual handling. Naturally the GPS 240 is also suitable for automatic changing.
The chuck seal prevents dirt penetrating between the chuck and the pallet. This simplifies maintenance and lengthens the life of the components. A lifting mechanism which operates on locking/opening protects the references when loading heavy workpieces.
- Seal protects the reference surfaces from dirt
- High locking force
- Inexpensive, lightweight pallets
- A lifting mechanism protects the references when loading heavy workpieces
Facts
- Repetition accuracy: 0.002 mm
- Clamping force: 30000 N (with force boost, 80000 N)
- Indexing accuracy: 0.005 mm

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.

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.

MacroJunior – small, but big enough for most electrodes
A reference system tailored for modern EDM technology with automatic electrode changing and unmanned production.
The patented and compact MacroJunior system is intended mainly for small electrodes. Unlike other Macro systems, in MacroJunior the chuck, not the electrode holder, has positioning tongues. A design which means that the electrode holders can be supplied at a very attractive price.
The design with three reference points in the X-, Y- and Z-directions means that, despite any tolerance variations in the holder, the coupling repeats very accurately when it is locked with its screw connection.
Tests and calculations done by independent researchers and institutes have established that MacroJunior, despite its small size, offers greater torsional rigidity than other significantly larger and costlier systems on the market.
- More compact than any other system
- Inexpensive electrode holders for good economy
- Movable drawbar eliminates bending forces

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.

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.
