CNC Lathe Line Features Range of Spindle Motors
IMTS 2018: Okuma America’s LU7000 EX two-saddle CNC lathe has a wide range of spindle motor specifications for manufacturing large parts.
Okuma America’s LU7000 EX two-saddle CNC lathe has a wide range of spindle motor options for manufacturing large parts. The machine features a large, 2-m bed and available spindles rated at 45, 55 and 75 kW. The company says it provides stable, heavy-duty cutting with full utilization of upper and lower turrets. Additional machining accuracy is said to be achieved with the company’s Thermo-Friendly Concept, which compensates for temperature changes that occur during machining. Ceiling and front-door shower coolant enable complete chip removal and improved visibility.
The machine accommodates a turning diameter ranging to 35" and a workpiece weight ranging to 24,000 lbs. Four types of spindle bore diameter and five different distances between centers are available. The milling tool spindle, self-traveling tailstock and long boring bar can cut internal diameters as deep as 47". Paired with the company’s Machining Navi T-g threading function, the machine can perform threading operations with minimal chatter.
Running rotary milling cutters at the proper speeds and feeds is critical to obtaining long tool life and superior results, and a good place to start is with the manufacturer's recommendations. These formulas and tips provide useful guidelines.
With macros and canned cycles resident in the CNC on most contemporary turning centers, single point turning of OD threads can seem like almost a default process decision. However, for numerous applications, OD thread rolling has inherent advantages as an alternative to cutting threads.
Fast CNC processing and high-pressure coolant contribute to removing metal at dramatic rates. But what should a shop know about cutting tools in high speed machining?
