Our best estimate for the Brother TC-20A is $8,000 - $25,000 (used). 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-20a#price; the request is passed to Brother Industries or an authorised dealer.
The listed travels are 300 mm (11.8 in) in X, 200 mm (7.9 in) in Y and 200 mm (7.9 in) in Z, on a 300 x 200 mm (11.8 x 7.9 in) table rated for 30 kg (66 lb). In practice that means small parts in a vise or on a light fixture.
The TC-20B has 200 x 185 x 250 mm (7.9 x 7.3 x 9.8 in) of travel, a 30,000 rpm spindle, 16 tools and 40 / 40 / 45 m/min rapids. The TC-20A has more X and Y at 300 x 200 mm (11.8 x 7.9 in) but less Z at 200 mm (7.9 in), an 8,000 rpm spindle, a 16-position ATC and 30 m/min (1,181 ipm) rapids.
The listed control is the Brother NC-A00, Brother's own control. Programs and operator habits from a machine with a different control may not carry over unchanged, so check the manual and the installed control options before buying a used unit.
The listed positioning accuracy is +/- 0.005 mm and repeatability +/- 0.002 mm. Those figures could not be checked against Brother's current pages, so a used unit should be checked with a test part before relying on them for tight hole positions.
