TONGTAI FV-171 FV SERIES – 4-5 AXIS HIGH PRODUCTION VERTICAL/HORIZONTAL MACHINING CENTERS

Description

The Tongtai FV Series of single- and twin-spindle vertical machining centers is designed for mass production of complicated workpieces in the automotive, appliance, electronics, and energy industries. Fixed twin-spindle versions can process two individual machining tasks simultaneously, and the addition of a 5-axis trunnion table effectively creates a horizontal machining center. Machines spindles are 12,000 rpm with 40-taper toolholding systems.

A standard automatic pallet changer (APC) executes changes as fast as 4 seconds. A planetary gear provides high positional accuracy, zero backlash, long-term durability, and minimizes shop noise. The APC is servo-driven, saving energy and maintenance costs. Automatic production is possible with the integration of a robot on either a floor-type motion axis rail system or overhead gantry.

Optional built-in tilt/rotary tables or built-in tilt fixtures create a 5-sided or 5-axis machining center. The optional C-axis rotary table has a table size of 350mm (14″) for single-spindle or 220mm (8.8″) for twin-spindle models, both with a 360° stroke. The A-axis trunnion rotary table design has a stroke of -30° to 180° for both single and twin spindle models.

The machines’ automatic tool changer has a built-in tool carousel with capacity of 24 tools for single-spindle version or 48 tools for twin-spindle. An 84-tool magazine is optional. To minimize tool change time, the machine determines whether to move the spindle or the magazine to retrieve the tool. In either case, tool change time is 1.2 seconds. A coolant-thru spindle system is optional as are various chip conveyors to accommodate different materials and chip sizes.

Rapid traverse rate for both single and twin-spindle models is 75m/min (2,952 in/min) in X/Y/Z and 50/100 rpms in the A and C axes respectively.
