CNC bevel gear cutter has small footprint
CNC bevel gear cutting machine has a design that permits the shortest possible structural overhang of both cutter and work for maximum stiffness and thermal stability.
Grinding and hobbing done in one machine
Universal CNC gear grinding machine uses high speed, direct drive spindles for different grinding methods such as profile or generating using a worm-type wheel.
The optimised ratio of the dimensions of the grinding wheel, with a width of 180mm and a maximum diameter of 220mm, permits long tool life and short non-productive times.
A maximum spindle speed of 6,000 rev/min allows the maximum cutting speed of 63m/s for vitrified-bonded wheels to be exploited to the fullest.
To dress these worms, we supply two systems customized to your application.
To achieve short, thread number-independent dressing times, dressing with a diamond-plated dressing gear and roller is optimal for larger production volumes.
In addition, this machine is equipped with a fully-automatic dressing unit (Gleason dresser) with conventional CNC dressing technique to meet high requirements with regard to quality and flexibility.
The machine can be loaded by a fast, solid two-station ring loader.
Standard part storage automation is a pallet ring conveyor, a spin-clean station can be integrated.
The 245TWG is available with the latest Siemens CNC control as standard.
The technology software running on the machine, together with the optimised ergonomics of the user interface for simple data input, support the operator by automatically calculating machine setting and machining data.
The integrated graphics and comprehensive plausibility checks ensure a safe and simple to learn operation of the machine.
