Corochuck 930

The Corochuck 930 — Sandvik Coromant’s high-precision hydraulic chuck — is now available for Big Plus spindle system users, providing a secure tooling performance in milling and drilling operations. The chuck is said to be ideal for meeting the demands for high run-out precision.

Corochuck 930 high-precision hydraulic chuck from Sandvik Coromant

The design of the Corochuck 930 is said to ensure excellent torque transmission to improve the performance of solid-carbide endmills, drills and reaming tools.

When used with milling tools, low run-out of the cutter will also ensure consistent feed per tooth, resulting in predictable tool life and allowing component tolerances to be maintained more easily.

Furthermore, the performance of the Corochuck 930 can be repeated over multiple clamping cycles to retain high-quality component surfaces — the product is also designed with dampening features that serve to minimise vibration during the machining process.

The Corochuck 930 can be quickly tightened or released with a dedicated torque wrench, improving efficiency through fast and easy setups and changes. No other external equipment is required to clamp or unclamp the system.

Key features and benefits

  • Optimised design of the brazed clamping membrane promotes ultra-secure clamping with two supports on each side (fulcrums)
  • The chuck provides significantly less risk of tool pull-out
  • It ensures excellent torque transmission to improve performance of solid-carbide endmills, drills and reaming tools
  • When used with milling tools, low run-out of the cutter will also ensure consistent feed per tooth
  • Its performance can be repeated over multiple clamping cycles to retain high-quality component surfaces
  • It can be quickly tightened or released with a dedicated torque wrench, improving efficiency through fast and easy setups and changes
  • Chuck holds tolerances within microns to improve tool precision, surface finish and productivity; precision run-out can be measured at less than 4μm at 2.5 x DC. 
  • It is suitable for machine tools including lathes, machining centres, multi-task machines and driven tools in turning centres and VTLs
  • It is available in pencil, slender and heavy-duty design and is balanced according to DIN 69888
