Available from Absolute Machine Tools, Tongtai’s QMV-610AII+APC vertical machining center with automatic pallet changer is an upgraded version of the pervious QVM-610A+APC. The machine features a strengthened bed structure, decreased spindle saddle weight and greater pallet rigidity. Rexroth linear guideways ensure high performance even in heavy-duty cutting applications.
The APC structure has been modified to enable more side direction machining efficiency with pallet loads of 880 lbs in each side and a triple clipping device for improved stability. The APC is driven by a roller-gear-type motor with an indexing time of 4 sec., the company says. An intelligent loading device detects the workpiece weight and will automatically change the rotary speed to extend the usage life of the device. The tool-arm speed and rate of deceleration have been adjusted to deliver tool-to-tool times of 2 sec., the company says. A built-in encoder enhances tool-changing reliability.
