With rapid traverse speeds up to 2,362ipm (60m/min) in all axes and acceleration of 1.2g, Tongtai VTX series of drilling and tapping centers are for high-precision, high-volume machining applications. The machine has a compact footprint of 87" x 63" (2,210mm x 1,600mm) and a fixed column/moving table type design with Meehanite cast-iron frames and roller-type linear slideways.
The 21-tool turret-type ATC on VTX-5 and VTX-7 models offers tool change time of 1.4 seconds tool-to-tool and 1.9 seconds chip-to-chip. VTX-5A and 7A versions have a 20-tool arm-type ATC system that reduces tool change time to 0.8 seconds tool-to-tool and 1.3 seconds chip-to-chip.
A 7.5hp, 12,000rpm direct-drive spindle provides rigid tap speeds up to 6,000rpm. An optional 24,000rpm direct-drive spindle delivers high speeds for machining aluminum and magnesium parts and is an excellent choice for processing graphite. A BBT-30, dual-contact taper is standard for rigid milling. Coolant-through the spindle preparation and spindle chiller are also standard.
The standard Mitsubishi M80A control is suitable for applications ranging from production to high-speed machining. It features a 10.4" (264mm) touch screen with intuitive smart-phone type operation. A dedicated CNC CPU provides fast processing speeds while speed and accuracy comes from a high-response servo system with 1,000,000 pulse encoders. A Fanuc OiM-F control with 8.4" (203mm) LCD with a 2-year warranty is available.
