How much does the Brother TC-20A 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-20A is a small BT30 drilling and tapping center with 300 x 200 x 200 mm (11.8 x 7.9 x 7.9 in) of travel on the X, Y and Z axes, an 8,000 rpm spindle driven by a 1.5 kW (2 hp) motor, a 16-position ATC and a Brother NC-A00 control. It is not on Brother's current product pages, so the figures here are the listed ones and have not been checked against the maker.
The numbers describe a light machine. The table is 300 x 200 mm (11.8 x 7.9 in) and rated for 30 kg (66 lb), the whole machine weighs 850 kg (1,874 lb), and the footprint is 900 x 1,200 mm (35 x 47 in). That suits a vise or a small fixture holding aluminium or brass parts for drilling and tapping. It does not suit heavy steel workholding or deep cuts, which the 1.5 kW motor could not drive anyway.
Speed is modest. The spindle tops out at 8,000 rpm, where the TC-20B runs to 30,000 rpm, and rapids are 30 m/min (1,181 ipm) on all axes. Listed positioning accuracy is +/- 0.005 mm and repeatability +/- 0.002 mm. Wear can move a used machine away from those figures, so a test cut or a check with an indicator says more about the unit in front of you than the table does.
The 200 mm of Z also limits tooling: long drills plus a vise can use up the stroke quickly, so measure the stack-up of fixture, part and tool before buying for a specific job.

Strengths & Limitations
Strengths
- Compact 900 x 1,200 mm (35 x 47 in) footprint and 850 kg (1,874 lb) weight, easy to place in a small shop
- 16-position ATC for drilling and tapping sequences without manual tool changes
- BT30 spindle taper, so standard BT30 holders can be used
- Listed repeatability of +/- 0.002 mm
Limitations
- 1.5 kW (2 hp) spindle motor and 8,000 rpm limit both heavy cuts and small-tool speed
- Table load of only 30 kg (66 lb) on a 300 x 200 mm (11.8 x 7.9 in) table
- 200 mm (7.9 in) of Z restricts tool length and part height
- Figures could not be checked against Brother's current pages

Frequently Asked Questions
01
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.
02
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.
03
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.
04
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.
