Users of Chevalier’s QP-3572 vertical Machining Center in such industries as aerospace, defense, printing, automotive, construction, gas and oil product fields have experienced a dramatic increase in reliability and productivity.
“The QP-3572 vertical machining center has received praise from our clients for the machine’s rigid structure and high-precision for high productivity in large workpieces,” says Mike Plachetka, vice president of sales and machining systems at Machine Tool Diagnostics in Yorkville, IL, and a dealer of Chevalier products.
The QP-3572 machining center features XYZ box ways that are hardened and precision grounded. The box way surfaces are coated with Turicite-B and hand scraped for smooth movement. The extra Y-axis stroke (35.4") is suitable for the mold and die industries or job shop machining.
The heavy-duty, two-speed gear type headstock comes standard on the QP-3572 machine, along with a 6,000rpm, CT50 spindle taper. A forced-circulation cooling system is applied to bearings and gears in the gearbox. Also standard is the 30hp FANUC digital spindle motor that produces up to 451ft/lbs. torque at a lower speed.
“This outstanding cooling system reduces thermal expansion to a minimum and upgrades machining accuracy,” says Herbert Hou, Chevalier’s national sales manager.
Controlling the machine is a powerful FANUC 0i-MD controller that delivers rigid taping and AICC high-speed machining mode with a 40-block look-ahead. A front-loading PCMCIA port is standard for an optional memory card, which includes 1280M (512KB)/400 maximum program capacity. The FANUC control offers an Ether¬net function and data server, as well as a manual guide for 0i conversational programming, among many other standard features,
The special design of the floating-type tool release system provides a tool change without extra pressure on the bearings and absorbs the 6,600 lbs. of unclamping force generated during each tool release. “This design helps prolong bearing life, maintain accuracy and increase speed,” Hou says. The maximum tool diameter without adjacent tool is 4.7" for 24T and 5" for 32T. The tool holder accepts tools weighing up to 15 lb.
All machines are measured and calibrated after assembly by a state-of-the-art laser calibration equipment. This ensures precise verification and compensation of the machines, resulting in increased accuracy and repeatability. The machines are also given a ball-bar test to ensure the perfect circular interpolation.
