5 Advantages of a Collet-Ready Spindle
While typical CNC turning machines require a spindle adapter to install a collet or jaw chuck, many Hardinge products, including the Conquest H51 horizontal turning machine, have a unique collet-ready spindle design that eliminates the need for an adapter. Naturally, this makes changeovers quicker and easier, but the benefits don’t end there. Here are 5 more advantages:
- Because the entire spindle assembly is finish ground in place, the Conquest H51 Super Precision holds tolerances within the 2 – 3 micron range.
- The collet sits directly in the spindle so maximum rigidity and gripping power are transferred directly to the part and you can run at optimum RPM.
- Absence of an adapter means less weight is placed on the spindle and there is minimum overhang from the spindle bearings, so spindle accuracy is transferred directly to the workpiece.
- The unique design allows easy and accurate drawtube adjustment from the back of the spindle to provide quick changeovers from bar work to chucking work.
- The collet-ready spindle makes it possible to perform accurate hard turning and grinding, thus eliminating the need for dedicated grinding machines.
Hardinge also makes a number of workholding options for use with the collet-ready spindle including a variety of collets, 3-jaw power chucks and step chucks and closers. Contact your local Gosiger machine tool expert to learn more, and watch the Conquest H51 video to see the machine in action.
