Mazak featured recently its simple but innovative VERTICAL CENTER UNIVERSAL (VCU) 500A with a two-pallet changer to demonstrate cost-effective, highly productive small parts machining. In quick, simple setups, the small-footprint 3-axis vertical machining center accurately processes basic workpiece geometries up to 19.68" x 19.68" x 9.84" in size.
The VCU 500A comes standard equipped with a robust, high-performance 10,000-rpm, CAT 40-taper spindle that delivers exceptional metal removal capabilities in all common materials, including steel, aluminum and cast iron. Optional speeds of 12,000 and 20,000 rpm are also available so users can effectively match spindle performance with their part-machining requirements.
A cam-driven automatic tool changer significantly reduces non-cut times on the VCU 500A by quickly exchanging tools and getting the spindle back in the cut in the shortest time possible. The reliable tool monitoring on the machine maximizes production efficiency and lowers operating costs via early problem detection. Tool storage capacities of 30 or 40 tools ensure continuous machining operation and increased versatility.
The Mazak MX Hybrid Roller Guide System on the VCU 500A enables the machine to deliver high levels of durability and reliability, resulting in long-term accuracy. The innovative way system increases vibration dampening, extends tool life, handles higher load capacities and eliminates tramp oil in the coolant by utilizing a greener grease-based lubrication system.
The VCU 500 employs Mazak’s user-friendly SMART CNC that shortens job set-up times by allowing operators of all skill levels to quickly and easily develop machining programs. In fact, programming time is 75 percent faster with the SMART CNC when compared with machines using EIA/ISO systems.
The two-pallet changer on the VCU 500A increases spindle utilization and makes for continuous uninterrupted production. This simple and efficient automation feature enhances productivity by allowing operators to load, unload and inspect a part on one pallet, while the machine continues to work on a part fixtured on the other pallet.
