2012 BROTHER TC31B VERTICAL MACHINING CENTERS

Technical Description

The 2012 Brother TC31B is a 3-axis high-speed tapping center featuring a two-face quick-turn (QT) pallet system, enabling simultaneous machining on one pallet face while an operator loads and unloads workpieces on the other, thereby maximizing spindle utilization and throughput. The machine uses a BT30 taper spindle with a standard maximum speed of 12,000 RPM; a 16,000 RPM optional spindle is available for higher-speed cutting requirements. Each pallet face measures approximately 500 mm x 270 mm (19.7 x 10.6 inches), providing a compact work surface suited to small precision components. Axis travels are 350 mm (13.8 inches) in X, 250 mm (9.8 inches) in Y, and 350 mm (13.8 inches) in Z. The machine is governed by a Brother proprietary CNC control (B-series), which is compatible with Fanuc G-code and supports multi-axis operation when optional rotary devices are added. The quick-turn pallet changer rotates 180 degrees to transfer the machined part out of the cutting zone and bring the loaded pallet into position, enabling near-continuous production cycles with minimal idle spindle time. The overall machine footprint measures approximately 1,404 mm x 3,204 mm (55.3 x 126.1 inches), and the machine weighs approximately 2,090 kg (4,608 lbs). Standard equipment includes an automatic tool changer, coolant system, and chip management provisions. The TC31B is particularly well suited to production environments processing large quantities of small aluminum or non-ferrous components where cycle time reduction and operator efficiency are the primary performance drivers.
