Gear Skiving Machines with Direct-Drive Tables Handle High Workpiece Speeds
EMO 2017: Liebherr will feature its LK 300 and 500 gear skiving machines, which are based on components of corresponding large hobbing machines.
Liebherr will feature its LK 300 and 500 gear skiving machines, which are based on components of corresponding large hobbing machines. These machines are rigid and equipped with powerful spindles and direct-drive tables to handle high workpiece speeds. The drive works with an automatic control which is said to maintain optimal parameters. The machines are supplied on a turnkey basis with individual clamping fixtures for each workpiece. A ring loader is the machine’s standard workpiece changing device. The LHGearTec control system contains mathematical formulas for pressure and angle corrections said to improve quality via the machine’s kinematics. Automation options include a toolchanger, belts and robots.
How do you create products that are cost competitive and of the highest quality? Here are three approaches, one about a car manufacturer putting more emphasis on its capacity, one about a machine producer increasing efficiency through flowing parts, and one about a car maker assuring quality in production.
To produce high-precision ring gears in low- to mid-volumes, an emerging option is the use of five-axis machining centers. Mitsui Seiki CNC vertical and horizontal machining centers are being used in this application.
This manufacturer’s use of live-tool lathes overcomes labor cost in various ways. One of the latest sources of savings involves bringing another operation—hobbing—into these machines. INCLUDES VIDEO.
