Single-axis and dual-axis multi-spindle rotary indexers from Hardinge Inc. provide positioning and machining up to four parts at a time to add efficiency to the machining process by spending more time with the doors closed and the spindle running.
Part positioning and multiple-part processing benefits using a rotary indexer include: all parts can be machined efficiently with the same tool before going to the next tool; and on-center milling, drilling, boring, tapping and reaming applications can be performed on multiple planes of the part. Using a dual-axis rotary indexer gives the added benefit of machining at multiple angles on the workpiece.
The indexers will increase overall production by producing more parts per hour, thus lowering the cost-per-part, while providing a competitive advantage, the company reports. The units have a quick ROI with all of these time-saving advantages: optimized spindle utilization; reduced start up—open door, remove/place part, hit cycle start, close door for every two, three or four parts instead of just one; reduce X- and Z-axis tool movements, drastically decreasing cycle time; free up the operator to run other machines or perform other tasks; and eliminate the need for additional operations.
All Hardinge rotary indexers have a collet-ready spindle providing an assortment of part gripping options. Along with standard collets, Hardinge spindles accept Sure-Grip® expanding collets, step chucks, jaw chucks and face or fixture plates without the use of an adapter. Robust, dual-bearing spindles accommodate heavy axial and radial loads with the ability to run a quad unit with tailstocks. A maximum runout of 0.0002-inch total indicator reading is the Hardinge standard. Multi-spindle units are available in dual, triple and quad spindle configurations.blog comments powered by Disqus
