Feeler FTC-20(L)

Feeler prints the FTC-20(L) as one column covering two bed lengths. The standard FTC-20 turns 343 mm between chuck and tailstock; the L version, shown in brackets, turns 613 mm. Z travel follows the same pattern at 380 (650) mm.

Both are 8 in chuck lathes, with 10 in listed in brackets as the alternative. Maximum turning diameter is φ350 mm (φ13.8 in), the spindle nose is A2-6 and the top speed 4,500 rpm. Bar capacity is φ51 mm through a φ62 mm bore. This is the common size for general turning: flanges, shafts, sleeves and bar work up to about two inches.

Which length to take is a question of the parts. Chuck work and bar parts rarely use more than the short bed, and a shorter machine saves floor space. Shaft work between centres needs the L. The tailstock has an MT-4 taper on both.

The turret has 8 stations. That is fewer than the 10 on the smaller FTC-10, and it limits how many tools can stay set up when jobs change often: a typical part with roughing, finishing, grooving, threading, a drill and a boring bar already uses six. X travel is given as 175+25 mm, and rapids are 24/24 m/min on X/Z. Feeler describes the series as linear guide lathes with a FANUC controller for everyday production of small and medium-sized parts. No live tooling appears in this table; the maker's FTC-350 family is the place to look for that.
