Our best estimate for the Brother TC-31B is $60,000 - $85,000 (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-31b#price; the request is passed to Brother Industries or an authorised dealer.
Both have 350 × 250 × 350 mm (13.8 × 9.8 × 13.8 in) of travel and 50 m/min (1,968 ipm) rapids. The TC-31B holds 26 tools (+1) and runs 12,000 rpm, with 16,000 rpm as an option. The TC-31AN holds 18 tools (+1) and runs 16,000 rpm, with 22,000 rpm as an option. Pick the TC-31B for tool count, the TC-31AN for spindle speed.
No. Brother has discontinued the TC-31B, so it is bought used. Check whether the machine has the standard 12,000 rpm spindle or the 16,000 rpm option, and run every one of the 26 tool positions (+1) through a tool change before accepting it.
The axes move 350 mm (13.8 in) in X, 250 mm (9.8 in) in Y and 350 mm (13.8 in) in Z. The short Y axis is usually the limit: parts and fixtures deeper than that need a machine such as the TC-22B, which has 450 mm (17.7 in) of Y.
