With rapid traverse speeds of 2,362 ipm (60 m/min) in all axes and acceleration of 1.2 G, Tongtai’s VTX drilling and tapping centers — available from Absolute Machine Tools — are designed for high-precision, high-volume machining. A fixed-column/moving-table design with Meehanite cast iron frames and roller-type linear guideways provide rigidity as well as fast, precise movement.
Two types of high-speed automatic toolchangers (ATCs) are available. The 21-tool, turret-type ATC on the VTX-5 and VTX-7 models offers tool change time of 1.4 sec. tool-to-tool and 1.9 sec. chip-to-chip. The VTX-5A and VTX-7A versions have a 20-tool, arm-type ATC that reduces tool change time to 0.8 sec. tool-to-tool and 1.3 sec. chip-to-chip.
The 7.5-hp, 12,000-rpm direct-drive spindle provides rigid tap speeds up to 6,000 rpm. An optional 24,000-rpm direct-drive spindle delivers speeds adequate for machining aluminum, magnesium and graphite parts. A BBT-30 (Big Plus dual-contact) taper suits rigid milling. Coolant through the spindle is standard, as is a spindle chiller.
The Mitsubishi M80A control features a 10.4" (264-mm) touch screen with intuitive smartphone-like operation. A high-response servo system with 1,000,000 pulse encoders increases speed and accuracy. A FANUC OiM-F control with 8.4" (203-mm) LCD screen is also available.
