Overview

The Okuma LT3000 EX is a horizontal turning center with a main spindle and a sub-spindle and a 13.77 in maximum turning diameter. The main spindle is rated 22/15 kW (30/20 hp) and the sub-spindle 15/11 kW (20/15 hp), so the second side of the part gets roughly two-thirds of the power available on the first. Plan the heavy stock removal for the main spindle and leave the sub-spindle the lighter back-side operations.

Spindle speed is 45 to 5,000 rpm on the standard A2-6 nose. Okuma lists an A2-8 nose and a 45 to 4,200 rpm range in brackets as options. The bracketed range is the lower one, the usual trade for a larger nose, although the table does not state that the two go together.

Against the LT2000 EX, which lists 210 mm (8.27 in), the LT3000 EX offers about 66% more turning diameter. The headline table stops at diameter, power, nose and speed. Turning length, turret layout and rapid traverse are not in it and need to come from the full specification.

Strengths & Limitations

Strengths

Main spindle rated 22/15 kW (30/20 hp) with a 15/11 kW (20/15 hp) sub-spindle for second-side work
13.77 in maximum turning diameter, about 66% more than the 8.27 in of the LT2000 EX
45 to 5,000 rpm on the standard A2-6 nose, with an A2-8 nose listed as an option

Limitations

The sub-spindle has less power than the main spindle, 15/11 kW against 22/15 kW, so heavy cuts belong in the first operation
The optional speed range tops out at 4,200 rpm instead of 5,000 rpm
Okuma's headline table gives no turret, driven-tool, turning length or rapid traverse rows for this model

Best For

Parts finished on both sides in one cycle using the main and sub-spindle Chucked parts up to a 13.77 in turning diameter First-operation roughing on the 22/15 kW (30/20 hp) main spindle

Frequently Asked Questions

01 What are the spindle ratings on the LT3000 EX?

The main spindle is listed at 22/15 kW (30/20 hp) and the sub-spindle at 15/11 kW (20/15 hp). Speed is 45 to 5,000 rpm on the standard A2-6 nose. An A2-8 nose and a 45 to 4,200 rpm range appear in brackets, which is how Okuma marks options.

02 How does the LT3000 EX compare with the LT2000 EX?

It is the larger machine. The LT3000 EX lists a 13.77 in maximum turning diameter against 210 mm (8.27 in) on the LT2000 EX. Its standard nose is A2-6 with A2-8 optional, where the LT2000 EX starts at 140 flat with A2-6 as the option, and its top speed is 5,000 rpm against 6,000 rpm on the LT2000 EX.

03 What should I confirm before ordering an LT3000 EX?

The headline table covers turning diameter, spindle power, nose and speed. It has no rows for turning length, turret configuration, driven tools, bar capacity or rapid traverse. Get those from the full specification, and settle whether you want the A2-6 nose at 5,000 rpm or the optional A2-8 nose.
