Shrink-fit chuck, vibration-damped −

ISO 12164-1 (DIN 69893-1) Vibration damping

• High-temperature steel.
• Integrated length adjustment of the tools.
• For HSS and solid carbide tools.
• Shanks hard turned (smooth cutting action!).
• With RFID/Balluffchip bore.
• With coolant channel bores and threads that can be sealed. 30 8344
• With tapped holes on each side for balancing screws.
• Reinforced version/contour. Carbide core drilled through, mounted in
• Polished surface. an aluminium cylinder – optimum shock Specially mounted carbide core in the shrink-fit chuck body. absorption characteristics!

Advantage: Vibration-damping.

• Better workpiece surface finish.
• Optimised tool life.
• Increased process reliability.
• Lower corrosion tendency due to polished surface.

Application: For clamping tools with plain shank (h6 shank tolerance). Suitable for inductive, contact and hot air shrink-fitting units.

Optional extras: HSK coolant tube No. 309880, A Socket wrench No. 309890, L2 Shrink-fit unit, accessories No. 354210 – 354440, Balancing screws set No. 309906 size 180.

Quick-change tapping chucks for synchronised spindles

• With minimum length adjustment (MLA), by means of a damping element.
• Increases tool life of taps by up to 300 %.
• Internal coolant supply up to 50 bar.
• Secure clamping for ER collets in quick-change tapping collets.
• Run-out of shank taper to the tapping collet taper < 3 µm.

Application: On machining centres with synchronised spindles.

• For compensating the difference in pitch between tap/synchronised spindle.
• For compensating the pitch tolerances of taps.

Optional extras: See No. 308600 - 308806 for pull studs. Coolant feed pipes for HSK, see No. 309880. See No. 309890 for plug-in sockets for HSK. D D 1 Quick-change tapping collets and extensions, see No. 338120 – 338142.
