Machine tools are at the heart of modern manufacturing – and their drive system plays a decisive role in determining how accurately, how quickly and how reliably they operate. CNC milling machines, lathes, grinding machines and honing machines place high demands on torque, speed, lack of play and smooth running. Direct drives are not always the best solution – often, a precision custom gearbox is the more cost-effective and high-performance option.

CHEMNITZER ZAHNRADFABRIK develops custom gearboxes for machine tools that combine manufacturing precision, durability and efficiency in one.

Typical requirements for the gearbox

• Minimal rotational play for maximum positioning accuracy
• High torsional stiffness for stable, low-vibration operation
• Transmission of high torques whilst maintaining precise speed control
• Low-noise operation for pleasant working environments and sensitive machining processes
• Long service life under varying loads in continuous operation
• Compact design for integration into confined machine housings

What we offer

We design machine tool gearboxes with a particular focus on low backlash, rigidity and smooth running. Our experience with superimposed and shift-type gearboxes for machine tools is demonstrated by numerous completed projects. The design is always tailored to the specific machining process – not to a generic machine type.

Typical gearbox types and application examples

• Superimposed gearboxes for adjusting grinding wheels during honing
• Hydraulically shiftable, low-backlash planetary gearboxes for main drives with customized output shafts
• Superimposed gearboxes for adjusting cutting edges during reaming with a high-reduction planetary stage
• Low-backlash saw gearboxes with adjustable rotational flank clearance
• Hydraulic motor gearboxes for responsive main spindle drives
