Five-Axis VMC with Rotary, Fixed Tables

Fortune International’s Vcenter-AZ800 is a five-axis VMC equipped with a swivel head on the traveling column to implement five-axis machining on large parts with diameters ranging to 39.4".

Fortune International’s Vcenter-AZ800 is a five-axis VMC equipped with a swivel head on the traveling column to implement five-axis machining on large parts with diameters ranging to 39.4". Its rotary table is built next to the fixed table.

The machine also features a twin-arm type ATC able to hold 40 tools in order to facilitate quick and reliable tool changeover. The 40-tool magazine is included as standard with an optional 60-tool magazine also available. The swivel head (B axis) with built-in 29.5-hp, 15,000-rpm spindle with roller gear mechanism is designed to minimize backlash and promote high accuracy at an arbitrary angle. A Hirth coupling is included as standard to clamp the swivel spindle at every 1-degree indexing position to enhance rigidity for heavy milling and drilling.

The BCV-40 tooling system offers additional clamping to reduce spindle runout at high rpm. The roller-cam-drive rotary table with a diameter of 31.5" (C-axis) features a load capacity of 2,640 lbs, suitable for loading big or heavy parts. 8+1 hydraulic/pneumatic ports are available as an option to direct the power through the C axis and pallet for multiple point clamping. Air sealing detecting can be also implemented to assure clamping quality.

A fixed table with dimensions of 49.2" × 31.5" extends the application on three- or four-axis machining. With the C axis clamped by the brake, the fixed table and rotary table afford parts as heavy as 5,280 lbs. A longer fixed table with dimensions 82.7" × 31.5" is available as an option to load another rotary table (A axis) with tailstock for alternative applications.
