MicroCentric Corp. has introduced a new quick-change compensating collet chuck for applications where shafts are machined between centers. The chuck features a pullback design with a floating collet seat and incorporates a mounting in the ID of the chuck body for centers or other types of locators.
The floating collet seat design together with vulcanized quick change collets allows the collet to compensate up to 1.5mm (.060”). The floating collet seat is sealed and the chuck is lubricated for life requiring minimal maintenance. The MicroCentric compensating chuck features a compact OD and short overall length compared to conventional compensating chucks and therefore provides greater rigidity and tool clearance.
All components are made from hardened alloy steel which are precision ground for highest accuracy and long-term performance. The chuck generates a maximum clamping force of 84 kN (18,884 lbs) and is rated for spindle speeds up to 6,000 rpm.
Related Glossary Terms
- centers
centers
Cone-shaped pins that support a workpiece by one or two ends during machining. The centers fit into holes drilled in the workpiece ends. Centers that turn with the workpiece are called “live” centers; those that do not are called “dead” centers.
- chuck
chuck
Workholding device that affixes to a mill, lathe or drill-press spindle. It holds a tool or workpiece by one end, allowing it to be rotated. May also be fitted to the machine table to hold a workpiece. Two or more adjustable jaws actually hold the tool or part. May be actuated manually, pneumatically, hydraulically or electrically. See collet.
- clearance
clearance
Space provided behind a tool’s land or relief to prevent rubbing and subsequent premature deterioration of the tool. See land; relief.
- collet
collet
Flexible-sided device that secures a tool or workpiece. Similar in function to a chuck, but can accommodate only a narrow size range. Typically provides greater gripping force and precision than a chuck. See chuck.
- inner diameter ( ID)
inner diameter ( ID)
Dimension that defines the inside diameter of a cavity or hole. See OD, outer diameter.
- outer diameter ( OD)
outer diameter ( OD)
Dimension that defines the exterior diameter of a cylindrical or round part. See ID, inner diameter.
