Hardinge Swiss-type Collets are ground to precise size and TIR to meet precision machining requirements with a standard accuracy that rivals the industry! Every collet and guide bushing is inspected on a Hardinge Super-Precision (.000015" TIR) headstock before reaching the stockroom.
Hardinge manufactures to Swiss quality for all brands of Swiss-style machines and cam-operated lathes. Extended-Nose Collets feature added nose length, flat or tapered, for doing pick-off work or to compensate for tooling interference. An Emergency Collet can be machined to the desired bore size. Emergencies are also available in extended-nose for added nose length.
Hardinge round Swiss Guide Bushings are carbide-lined to keep the stock clean and unmarked. Specials are available in hardened steel, Meehanite lining, angular & zig-zag slotted and extruded shapes. Escomatic counter collets and guide bushings can be manufactured to order. Hardinge also carries bar loader collets.

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.

The Power Collet Chuck is the collet chuck for the highest machining capacity in high-speed manufacturing. The optimized design with better construction combines high rigidity with vibration dampening features, giving more protection to machines, spindles and tools. The universal Power Collet Chuck is a unique high performance chuck that can also be used with standard collets.
– High runout accuracy: 0.005 mm at 3 x D with Haimer Power Collets
– 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 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.
Craftsman manufacture expanding mandrels tailored to your exact specifications. Many different mounting styles are available, including: spindle nose, between centres, 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 Craftsman can have the following features:
Single taper sleeves
Positive clamping and release
High levels of concentricity – to 0.005 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. |

- 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

- flange opening is at top central position for easy operator
access, and to avoid the disassembly of the opening button
in the DX or SX safety chucks;
- a safety button first needs to be pushed in before the
flange will open. Designing the button to be pushed
eliminates potential accidental opening by centrifugal force.
- components are finished to a high quality, with the safety
flange being dynamically balanced and chrome plated as
standard.
- the inserts are replaceable and designed in a variety of
shapes and sizes such as alveolar, square, round-square. |
