Our best estimate for a cnc lathes / turning center in this class — not a quote from Okuma. Configuration moves it a long way.

Overview

The Okuma LU7000 EX is a heavy CNC lathe: 900 mm (35.43 in) maximum turning diameter, 2,000 mm (78.74 in) of turning length and a spindle that starts at 45/37 kW. Two higher ratings, 55/45 kW and 75/60 kW, are listed as options.

The spindle is configured for the work. Standard is a JIS A2-15 nose at 10 to 1,500 rpm. The options are A2-20 and 725 flat noses and three slower ranges: 8 to 750 rpm, 5 to 500 rpm and 5 to 350 rpm. With three optional ranges, two optional noses and two optional motors, the combinations cannot be read off the table one for one, so work through them with Okuma against the diameters and materials you cut. The A2-20 and 725 flat noses and the 5 to 350 rpm range are the same listings that appear on the LOC650 oil country lathe.

Okuma's table gives the lower turret, at 8 to 10 stations, and has no row for the upper turret's station count. Rapid traverse is 20 m/min. Next to the LU4000 EX, which turns 480 mm (18.90 in) by 1,250 mm (49.21 in), this is close to double the diameter with twice the standard power.

Best For

Large shafts and rolls up to 900 mm (35.43 in) in diameter and 2,000 mm (78.74 in) long Heavy roughing with the optional 75/60 kW spindle Large chucks and heavy workholding on the optional A2-20 or 725 flat nose

Frequently Asked Questions

01 What spindle power options does the LU7000 EX have?

The standard rating is 45/37 kW. Okuma lists two options in brackets, 55/45 kW and 75/60 kW. Each rating is given as a pair of figures; plan long continuous roughing around the lower figure of the pair you choose.

02 What speed ranges are listed for the LU7000 EX?

10 to 1,500 rpm is standard on the JIS A2-15 nose. Three optional ranges are listed: 8 to 750 rpm, 5 to 500 rpm and 5 to 350 rpm. A2-20 and 725 flat noses are the optional spindle noses. The table does not state which range pairs with which nose or motor.

03 How does the LU7000 EX compare with the LU4000 EX?

It is far larger. The LU7000 EX turns 900 mm (35.43 in) by 2,000 mm (78.74 in), where the LU4000 EX lists 480 mm (18.90 in) by 1,250 mm (49.21 in). Its standard spindle is 45/37 kW against 22/15 kW on the LU4000 EX, and its top speed is 1,500 rpm against 4,200 rpm on the LU4000 EX.
