Okuma’s large capacity lathesbring heavy muscle to the oil industrySo precisely designed for the needs of the oil industry, the LOC500 and the LOC650 are named for the specifications driving their development: Lathe Oil Country. The 4-axis configuration makes them possible to perform the tightest threading functions on big pipes with precision and speed. Each machine has three spindle bore variations specifically designed for the series, and is able to accommodate large diameter pipes.

LOC500

Max turning dia x length: ø600 x 2,000 mm (ø23.63 x 78.74 in.)

LOC650

Tailored to the oil industry

Upper/lower turrets: 200-mm thick (7.87 in.)

• That means better premium thread applications• For high mechanical and hydraulic performance (with

multiple sealing areas; particularly efficient in moderate- to high-pressure gas well applications)

• The programmable tailstock and auto door reduces operator intervention and adds to the efficiency of the part transfer.

Highlighted SpecsFeaturing:• 4-axes productivity/simultaneous cutting using 2 tools• Spindle bores (max)• Spindle power (max)• Okuma’s Oil Field (threading suite)Options: (partial list)• High pressure coolant• Auto door• Feed hold during threading• Collision Avoidance System (CAS)• Rear chuck

LOC500 LOC650

Okuma's Oil Field "Threading Suite" is custom designed to combine variable spindle speed threading (VSST) and harmonic spindle speed control (HSSC) that delivers an exact match between infeed patterns and cutting increments. Okuma lathes are known for their power and control. Though huge in scale, the LOC Series delivers Okuma precision with optimum efficiency.

Featuring• Uniform helical threads

(OD or ID)• No backtracking

• More closely maintained limits• High mechanical and hydraulic

performance (multiple sealing jobs)

The Benefits• Better premium thread applications

• Save time, less danger of thread damage

• Improved thread quality• Efficient in moderate to high-pressure

gas well applications

Okuma Control OSP-P300LSatisfaction from complete control of a machine tool

As a “machine & control” builder, Okuma makes further strides in machine tool manufacturing with

this superb Control featuring “Easy Operation.” Okuma took a close look at the way machinists

actually operate machine tools, to help them create smoother and more effective ways of producing

parts. Novice operators as well as professional machinists get complete control—and satisfaction.

Moreover, what you want to see and do conveniently come together in a “single-mode operation.”

First, select one of three operation screens. Then simply touch the screen or press a function key to

see and do your job.

World’s first “Collision-Free Machines” Chatter-free applications for lathes

CAS prevents collisions in automatic or manual mode, providing risk-free protection for the machine and great confidence for the operator.

Chatter in a lathe can be suppressed by changing spindle speeds to the ideal amplitude and wave cycle —without decreasing spindle speed.
