Synchronous Control of Skiving Technology

"Toyoda's new GS300H5 Gear Skiving Center is the first in the world to equip a skiving function to a general purpose horizontal type machining center, through which mass production of gear parts is achieved," said a Toyoda spokesperson. "CNC controls and a high speed rotary table were developed specifically to achieve high-speed, multifunctional machining, as a compact and light weight product, simple in programming functions. Recent finalist for Automotive News' 2017 PACE AWARDS (see link below) the GS300H5 machine with robot loading ran gear skiving demonstrations on internal and external surfaces of a Torson gear workpiece."

In recent years, the energy saving needs of vehicles has led to an increase in demand for gears to be compound and compact in accordance with hybrid vehicles and multistage automatic transmissions. Individual, conventional machining processes of lathe, hobbing, gear shaping, chamfering and drilling machines are essential for the gear making process, however separately executed are less efficient. "The single-chuck machining of the GS300H5 Gear Skiving Center integrates all gear part machining processes for a more functional and cost efficient shop floor," said the spokesperson.

Toyoda's GS300H5 Gear Skiving Center is offered with a high-speed rotation workpiece C-axis made more compact with a built-in motor while supporting automatic hydraulic fixtures. Featured alongside the machine is the newly developed TOYOPUC-GC70 control. The technology displays content of NC program by using NCSFC and simplifies inputting gear data, tool data and cutting conditions shown on the screen.

Feedrates on Toyoda's GS300H reach 60 m/min with travels on the X-, Y- and Z-axes at 730 mm x 650 mm x 850 mm. The shown Gear Skiving machine is complete with a 6,000 RPM 50 taper spindle with motor rates of 30/25 kW. Rotating speed on the C-axis reaches 3,000 RPM at a torque of 160 / 90 Nm. It is possible to see the new GHS300H HMC taking up just 2,745 mm x 4,510 mm of floor space, at JTEKT Toyoda America's Headquarters in Arlington Heights, IL.
