The Vertical Center Nexus (VCN) 530C-II TT from Mazak features twin tables to increase a shop’s manufacturing flexibility and provide cost effective processing of both smaller and larger, longer workpieces on the same machine.
Two integrated load stations located at the front of the machine provide for faster and easier part loading/unloading.
Twin tables deliver the continuous production benefits of a two-pallet change, says the company. Smaller separate workpieces fixture onto each of the two machine tables–measuring 645 to 548 mm (25.4 x 21.6 in.)– 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 1,316 mm (51.18 in.) long and 549 mm (21.6 in.) wide.
With axis travels of 1,488, 528 and 508 mm (58.6, 20.8 and 20.0 in.) in X, Y, and Z, the machine’s twin tables each accommodate workpieces up to 620 mm long x 677 mm wide x 470 mm high (24.41 x 26.65 x 18.5 in.), and weighing as much as 1,323 lb. The single table handles workpieces as big as 1,200 mm long x 677 mm wide x 470 mm high (47.24 x 26.65 x 18.5 in.) that weigh up to 1,200 kg (2,646 lb). All within a machine that has a footprint of only 4,399 x 3503 mm (173.22 x 137.8 in.).
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.
