Brother TC-22B

The Brother TC-22B is a high-acceleration column traverse tapping center that expands on the TC-20B with a larger work envelope and enhanced servo dynamics for faster cycling on small precision parts. It is positioned as the performance step-up in the TC-B tapping center series.

X/Y/Z travels are 400 x 300 x 250 mm (15.7 x 11.8 x 9.8 in). The spindle runs at 10,000 rpm standard with a 2.2 kW motor on BT30 taper. Optional spindle speeds up to 30,000 rpm are available. The 21-tool ATC provides significantly more tool capacity than the TC-20B, enabling more complex drilling and tapping programs.

The TC-22B uses the same column traverse architecture as the TC-20B, where the spindle column moves in X rather than the table. This reduces table-side moving mass and enables high acceleration rates well-suited to small-part high-mix production.

High acceleration is the defining specification of the TC-22B over the TC-20B — faster X and Y acceleration reduces non-cutting repositioning time in programs with many hole operations. The CNC-B00 control is optimized for high-speed tapping cycles with rigid tapping and synchronization built in.

Machine weight is approximately 1,200 kg with a 1,100 x 1,600 mm footprint — still compact enough for space-constrained cells. Table load capacity is 50 kg.

New machines price $50,000-$70,000. Used units from 2014-2022 trade $22,000-$48,000.
