Our best estimate for the Brother TC-20B is $40,000 - $60,000 (new). This is an estimate for a vertical machining centers (vmc) in this class, not a quote from Brother Industries; configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/brother-tc-20b#price; the request is passed to Brother Industries or an authorised dealer.
Travels are 200 mm (7.9 in) in X, 185 mm (7.3 in) in Y and 250 mm (9.8 in) in Z. Parts and fixtures have to fit within that small envelope, so the machine suits miniature and small precision parts rather than plates or housings.
The TC-31AN has 350 x 250 x 350 mm (13.8 x 9.8 x 13.8 in) of travel, 18 tools (+1), rapids of 50 / 50 / 50 m/min and a 16,000 rpm spindle with 22,000 rpm optional. The TC-20B is smaller at 200 x 185 x 250 mm (7.9 x 7.3 x 9.8 in) with 16 tools, but its spindle runs to 30,000 rpm.
