How much does the Thermwood Model 77 cost?
Estimated price range
Our best estimate for a cnc router in this class — not a quote from Thermwood. Configuration moves it a long way.
Overview
The Thermwood Model 77 is the large-format 5-axis CNC router in Thermwood's range: every listed table is 10' wide, starting at 10'x10' and running through 10'x20', 10'x30' and 10'x40', then up in 10' increments in length. The standard spindle is 12 HP with a 24,000 RPM maximum.
Size is the whole point. The largest single table on the Model 67 is 7'x10' and on the Model 90 it is 5'x10' or 10'x5', so the smallest Model 77 already exceeds both, and length is open-ended. That makes it the choice for work that cannot be split into smaller pieces, such as long trimmed panels and large patterns. The extended Z-axis option reaches up to 60", the same ceiling as the Model 90.
It also has the largest spindle option of the three five-axis models, with 16 or 19 HP listed above the standard 12 HP. For tooling, Thermwood lists a 4 Position Automatic Tool Changing System and a 12 Position Under Gantry Bar Style Automatic Tool Changer, the latter described as standard on 10-foot wide machines. Since every listed size is 10' wide, ask which changer a given configuration ships with. Neither machine weight nor rapid rates are on Thermwood's page, and a table of this length needs building space to match. Control is Thermwood SuperControl.

- 12 Position Under Gantry Bar Style Automatic Tool Changer listed as standard on 10-foot wide machines
- Extended Z-axis up to 60" available as an option
Limitations
- No table narrower than 10' is listed, so floor space is substantial even at 10'x10'

Frequently Asked Questions
01
Thermwood lists 10'x10', 10'x20', 10'x30' and 10'x40' tables, and then larger in 10' increments in length. Width is 10' throughout. The page gives no upper limit on length, so the practical limit is the building and the quotation.
02
Two systems are listed: a 4 Position Automatic Tool Changing System and a 12 Position Under Gantry Bar Style Automatic Tool Changer, which Thermwood describes as standard on 10-foot wide machines. All listed table sizes are 10' wide, so confirm with Thermwood which changer, or both, a given machine includes.
03
12 HP is standard, and 16 or 19 HP are options, with a maximum speed of 24,000 RPM. The 19 HP option is the largest listed on Thermwood's five-axis routers; the Model 67 and Model 90 stop at 16 HP.
