Offers used Gear machines
Gear cutting machines are a special kind of tools. They are used in areas where you manufacture gears or gears - both outside and inside. The gear cutting machines produce by hobbing cutting movements, thanks to which you can set all the numbers of teeth, helix angle and profile shifts. They finished with the machines both straight toothing and inclined profile and work pieces that are to receive a thread-like structure. The device consists of a catchy or multi-start screw. This has flutes and forms with the work piece you want to interlock, a worm gear. The hob rotates and drives at the same time on the work piece along to generate the gear structure. With our gear cutting machines, the hob shifts continuously to introduce new teeth in the milling process. Thus, the teeth wear out evenly.

The gear cutting machines are suitable for various applications, such as the outer - Spur toothing Helical or where the individual teeth of the work piece obtained a tapered shaft. For large inner diameters instead internal gears are used in spirals tapered edges are serrated. Special forms are helical gears or other specialized devices. Milling with multi-axis control offer high speeds on the milling head and allow, therefore, working with high cutting speeds, even if you set waves with small numbers of teeth. Basis of such models is a vibration damping and bending rigid machine bed, such as polymer concrete. The vibration damping allows to mill surfaces very precisely and to obtain constant production results.
Here you will find the gear cutting machines as used models that have been renewed and adapted to the current state of the art. With the used machinery you save significantly in comparison with the initial purchase. Likewise, you will find deep hole drilling machines for large work pieces, grinding and milling machines, if you want to ablate metals and require high precision machining results. The offer includes furthermore measuring machines which operate even with the modern 3D metrology and support your manufacturing process.
