Collets

With the ability to rapidly dial in runout with complete control, users spend less time tapping on the side of the tool and resetting tools and collets. Overall efficiency is increased, machining costs are lowered, and scrap is reduced with easyZERO.

Walter expanded the TC630 Supreme product range to include UNJC4 to UNJC9/16, UNJF4 to UNJF9/16 and MJ3 to MJ10 thread sizes. Optional internal coolant is available for thread sizes starting from MJ4, UNJF8 and UNJC8 to provide effective chip removal on deep threads.

Because of its tool size capability, the PG48 holders require the use of a brand-new press-fit assembly unit called the PGS 48. The PGS 48 is an automatic hydraulic press that generates up to 15 tons of force to press and remove collets from the holders and is a single-series machine designed only for PG48.

The MMC collet chuck is precision ground and pre-balanced to 30,000 RPM at G2.5 with runout accuracy of 3 microns at 4 times the diameter – ensuring accuracy and reliability during high-speed operations.

Rineck offers standard and custom shrink fit tool holders with various connections including CAT, HSK, BT, SK, PSC and straight shank extensions. In addition, ER shrink fit collets are available. For added rigidity, flange or dual contact holders are available for CAT and BT tapers.  A clamping range from 3 mm to 32 mm is possible for both slim and standard styles. All tools are available in inch and metric sizes.

A titanium nitride (TiN) bearing nut improves rigidity as the uniquely designed gold ring reduces collet damage, reduces micro vibration with the collet flange, and eliminates friction with the collet. It improves the cutting rigidity and the quality of the cut compared to traditional collet chucks.

The DCN drills feature cylindrical shanks, which enable clamping of the drill in hydraulic toolholders (most recommended) or in spring collets. All drill bodies feature helical coolant holes. Prior to using the 12xD drill, it is recommended to drill a pre-hole by using a DCN 1.5xD drill or a centering drill.

Introduced in early July, the REGO-FIX standardized MQL PG collets are designed for tool shanks according to DIN 69090-3 and available for HSK-A 63 and HSK-E 40 toolholders. They are designed for machines using one-channel, internal through-spindle MQL systems and are beneficial for virtually any machining application.

The FHN Series method compensates for small offsets, including tilt, between the center axis of the tool and the pilot hole. By correcting the offset that occurs when attaching and detaching tools with the holder, it is now possible to achieve higher precision machining.

For OD clamping, the aluminum jaws can be machined to custom fit the workpiece. For ID clamping, the workpiece is placed over ID jaws, which expand outward using a tapered pin (available separately). The part repeatability is +/- 0.03 mm, and the jaw locating repeatability of +/-0.02 mm.
