With rapid traverse speeds up to 2,362 ipm in all axes and acceleration of 1.2 g, the Tongtai VTX series of drilling and tapping centers from Absolute Machine Tools Inc. (Lorain, OH) are fast, affordable solutions for high-precision, high-volume machining applications.
Their compact 8-inch-by-63-inch (2,210-mm-by-1,600-mm) footprint conserves shop floor space. A fixed column/moving table-type design with Meehanite cast-iron frames and roller-type linear slideways provides rigidity and fast, precise movement.
Two types of high-speed automatic tool changers (ATC) are available. The 21-tool turret-type ATC on the VTX-5 and VTX-7 models provide tool change time of 1.4 seconds tool-to-tool and 1.9 seconds chip-to-chip. The VTX-5A and VTX-7A have a 20-tool arm-type ATC that reduces change time to 0.8 seconds tool-to-tool and 1.3 seconds chip-to-chip.
The standard 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 high speeds for machining aluminum and magnesium parts and is suitable for processing graphite. A Big Kaiser Big-Plus BBT-30 dual-contact taper is standard for rigid milling. Coolant through the spindle preparation is standard, as is a spindle chiller.
Offered with a three-year parts-and-labor warranty, the Mitsubishi M80A control with 10.4-inch touchscreen features intuitive smartphone-type operation. A dedicated CNC CPU provides outstanding processing speeds. High-response servo system with 1 million pulse encoders results in speed and accuracy.
Fanuc OiM-F control with 8.4-inch LCD and two-year warranty is also available.
