Innovative twin-table delivers cost-effective processing of small and large, long parts
FLORENCE, Ky., Oct. 8, 2013 – Attendees of the DISCOVER 2013 event experienced the unique twin-table changing design of the Mazak VERTICAL CENTER NEXUS (VCN) 530C-II TT. With its twin tables, the machine increases a shop’s manufacturing flexibility and provides cost-effective processing of both smaller and larger, longer workpieces on the same machine. Plus, two integrated load stations conveniently located at the front of the machine provide fast and easy part loading/unloading as well as enhanced operator efficiency. 
Twin tables on the VCN 530C-II TT deliver the continuous production benefits of a two-pallet changer. Smaller separate workpieces fixture onto each of the two machine tables – measuring 25.4” x 21.6” – that move in and out of the machine within a 12-second change time for loading and unloading at the two front stations. The tables accept any combination of rotary tables, tilting tables and stationary vises to further part processing versatility, and all workholding system cabling remains connected during table changes.
For machining large and long workpieces, the machine’s two separate smaller tables join to form one big CNC controlled worktable measuring 51.18” long and 21.6” wide.
With axis travels of 58.6”, 20.8” and 20.0” in X, Y, and Z, the machine’s twin tables each accommodate workpieces up to 24.41” long x 26.65” wide x 18.5” high and weighing as much as 1,323 lbs. The single table handles workpieces as big as 47.24” long x 26.65” wide x 18.5” high that weigh up to 2,646 lbs. All within a machine that has a footprint of only 173.22” X 137.8”.
VCN 530C-II TT machine axes incorporate Mazak’s MX Hybrid Roller Guide System for high levels of durability and reliability that result 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 machine’s CAT 40-taper spindle is mounted on a rigid column and operates at speeds up to 12,000 rpm (18,000 rpm optional) with 15 hp (30 min rating) for heavy-duty and high-speed machining. A 30-tool (48-tool optional) capacity magazine-style tool changer provides fast change times and large capacity tooling for continuous machining operations.
Mazak’s MATRIX NEXUS 2 CNC control simplifies metalworking operations on the VCN 530C-II TT. Conversational part programming can be accomplished in MAZATROL language while the machine is cutting another part, or off-line in a CAD/CAM system. Once imported into the control, a realistic 3D cycle simulation verifies the machining cycle and checks for machine interferences, greatly reducing the need for test cuts.
