Gear Cutting

Gear Cutting Services Sydney

In Engineering practice, gears are used for many kinds of mechanisms, refers specially to toothed wheels. In other words, a gear is a wheel on which teeth have been formed. CNC Gear cutting is the process of creating a gear profile.

Gear Grinding Service

Gears are the most important machine elements in construction of transmissions, equipment and machinery. The requirements place on gears in terms of power transmission or running smoothness continues to rise steadily. Grinding is therefore one of the most important methods for fulfilling these high quality demands.

CNC Gear grinding is a finishing process to obtain a predetermined quality gear. Gear grinding is done to meet the exact requirements of form, dimension, and surface texture. Gear grinding gives a very high degree of dimensional accuracy.

Gear Grinding Advantages

  • Reduces vibrations and noise at high speeds
  • Increased root and flank load carrying capacity with reduced gear box dimensions
  • Precision gears are capable of carrying more load while reducing transient loads.
  • Higher the level of precision, the longer a gear system will last.
  • Ultimately lowers operational costs by reducing input power requirements
