Chuck Holds Tolerances Within Microns; Improves Tool Precision, Surface Finish and Productivity
Sandvik Coromant’s (Mebane, NC) CoroChuck 930 High Precision Hydraulic Chuck brings a secure tooling performance to milling and drilling operations. Perfect for meeting the demands for high run-out precision, extensive tests have shown this hydraulic chuck provides the best pull-out security available.
The secret behind the high precision and pull-out security is in the optimized design of the brazed membrane which allows for maximum secure clamping with two supports on each side (fulcrums).
This design ensures excellent torque transmission to improve the performance of solid carbide end mills, drills and reaming tools. This performance is repeated over multiple clamping cycles to retain high quality component surfaces and extend tool life. Additionally, the CoroChuck 930 is designed with dampening features that minimize vibrations during the machining process.
Based on a hydraulic tool clamping system, the CoroChuck 930 can be quickly tightened or released with a dedicated torque wrench, improving efficiency through quick and easy setups and changes. No external equipment is required to clamp or unclamp the system.
The chuck holds tolerances within microns to improve tool precision, surface finish and productivity. The precision run-out can be measured at <4 μm (157 μinch) at 2.5 × DC. This chuck is suitable for all types of machine tools that either have a rotating spindle or workpiece: lathes, multi-tasking machines and machining centers and driven tools in turning centers, and vertical turning lathes.
Available in pencil, slender and heavy-duty design, the CoroChuck 930 is balanced according to DIN 69888.
