How much does the Brother TC-31AN cost?
Estimated price range
Our best estimate for a vertical machining centers (vmc) in this class — not a quote from Brother Industries. Configuration moves it a long way.
Overview
The Brother TC-31AN is a discontinued tapping and machining center with a fast standard spindle: 16,000 rpm, with 22,000 rpm available as an option. Travels are 350 x 250 x 350 mm (13.8 x 9.8 x 13.8 in), the magazine holds 18 tools (+1), and rapids are 50 m/min (1,968 ipm) on X, Y and Z.
The 350 mm (13.8 in) Z stroke is generous for a machine of this X and Y, which leaves room for longer drills and taps or for taller fixtures. The 250 mm (9.8 in) of Y keeps parts narrow, so the TC-31AN fits work such as small housings, valve bodies and brackets rather than wide plates.
The related TC-31B shares the travels and rapids but lists a 12,000 rpm standard spindle with 16,000 rpm optional, and 26 tools (+1). Choosing between them is a trade of spindle speed against magazine size. The TC-31AN occupies 1,410 × 2,903 mm (55.5 × 114.3 in). Its listed table gives no spindle power, taper or table load, so check those on any machine offered.

Frequently Asked Questions
01
Both have 350 x 250 x 350 mm (13.8 x 9.8 x 13.8 in) of travel and 50 / 50 / 50 m/min rapids. The TC-31B has a 12,000 rpm standard spindle with 16,000 rpm optional and holds 26 tools (+1). The TC-31AN runs to 16,000 rpm as standard, 22,000 rpm with the option, and holds 18 tools (+1).
02
Brother lists a footprint of 1,410 × 2,903 mm (55.5 × 114.3 in). Add space for the operator, chip handling and maintenance access, and confirm the machine's weight and power needs on the plate, since the listed table does not give them.
