How much does the Brother TC-20B 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-20B is a very small, very fast-spindle machining center: 200 x 185 x 250 mm (7.9 x 7.3 x 9.8 in) of travel, a 30,000 rpm spindle and a 16-tool magazine, on a footprint of 900 × 1,717 mm (35.4 × 67.6 in). Brother no longer offers it, so it is found as a used machine.
The proportions say what it was built for. X and Y are both shorter than Z, and 30,000 rpm is a speed for small end mills and drills, not for face mills. Think of miniature parts and small precision components rather than general job-shop work. Rapids are 40 / 40 / 45 m/min (1,575 / 1,575 / 1,772 ipm), slower than the 50 / 50 / 50 m/min of the larger TC-31AN, which matters little over strokes this short.
The Brother table for this model is brief. It gives no spindle power, taper, table size or table load, so a buyer should establish all of those from the machine and its documentation before committing work to it.

Strengths & Limitations
Strengths
- 30,000 rpm spindle for small-diameter tools
- Footprint of only 900 × 1,717 mm (35.4 × 67.6 in)
- 16-tool magazine on a machine with 200 mm (7.9 in) of X travel
Limitations
- Travels of 200 x 185 x 250 mm (7.9 x 7.3 x 9.8 in) limit it to very small parts
- Discontinued, and the listed table omits spindle power, taper and table load
- Rapids of 40 / 40 / 45 m/min (1,575 / 1,575 / 1,772 ipm), below the 50 m/min of the TC-31AN

Frequently Asked Questions
01
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.
02
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.
