Upgraded VMC with Automated Pallet Changer



QMV-610AII+APC, Tongtai's new vertical machining center (VMC) with automated pallet changer, is an upgraded and improved machine from the QVM-610A+APC.

"The mechanical designers analyzed the machine structure and selected spindle distortion as a main improvement," said a company spokesperson. "Along with cross-evaluation of linear guide ways, ballscrews and castings, many other improvements were also implemented.

"By strengthening the machine bed structure, decreasing the spindle saddle weight and improving pallet rigidity, the structure of the moving column was enhanced. German made REXROTH linear guideways offer enhanced machining performance in heavy-duty cutting. After practical tests, rigidity of the three axes significantly increased.

"The APC structure has been improved to enable more side direction machining efficiency with pallet loads of 880 lbs. in each single side, and a triple clipping device to improve stability. The APC is driven by a roller gear type motor with an indexing time of only four seconds. Furthermore, an intelligent loading device function detects the workpiece weight and will change the rotary speed automatically to extend the usage life of the device.

"The efficiency of tool changing has been increased by adjusting the rate of deceleration and improvement of tool arm speed. Tool to tool time is now two seconds. Furthermore, the built-in encoder enhances the reliability during tool changing and has successfully finished the millionth tool changing test in Tongtai's factory."

Tongtai machine tools are available through Absolute Machine Tools, Inc., an importer and distributor of CNC machining and turning equipment.
