Turning Centers Feature Y Axis, Larger Part Capacity
IMTS 2018: Doosan Machine Tools will display its Lynx 2100LY series of compact turning centers with a Y-axis.
Doosan Machine Tools’s Lynx 2100LY series of compact turning centers with a Y-axis features a variety of tool holders (both static and live tools), a tool setter, a parts catcher and a parts conveyor.
The machines’ 15-kw (20-hp) spindle rotates at a maximum of 4,500 rpm. It features a larger turning capacity than previous models while maintaining the same footprint . An additional Y-axis and optional subspindle speed and simplify machining of parts with diverse and complex shapes, the company says.
Other standard features include a 12-station, servo-driven BMT tool turret with a half index feature in 24 positions, Easy Operation Package (EOP) software, and a CNC tailstock. The turning center is designed with a rigid bed structure and incorporates roller-type LM guides for all axes. It is available in a 6" and an 8" chuck size accommodating a turning diameter ranging to 11.8" and a turning length ranging to 20".
One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.
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.
Creating threaded holes in titanium alloys calls for proper techniques based on an understanding of both the properties of these materials and the peculiarities of the tapping process.
