Nylon gears from Laser Lines are commonly used in many automotive, electronic and medical applications, as well as in various industrial machines.

Nylon gears offer increased service life because they wear less than metal gears (even though they require less lubrication) and reduce gear noise.

Adding a 20 per cent to 30 per cent glass fill to the nylon blend increases the material’s stability, rigidity and wear resistance, according to the company.

This application demonstrates the ability of a Synrad CO2 laser to precisely remove the machining hub from the centre of this helical-cut gear after the last manufacturing step.

The laser cutting setup consisted of a Synrad Firestar F201 laser delivering the beam via XY ‘flying optics’ into a cutting head containing a 127mm (5.0in) plano-convex focusing optic.

This optic produces a 203-micron (0.008in) spot with a 6.3mm (0.25in) depth of focus.

During the cutting process, 2.8bar (40psi) of breathing-grade bottled air was supplied coaxially, with the beam as gas assist.

The machining hub, which is 2.4mm (0.093in) thick, was cut from the front face of the gear by trepanning a 30.7mm (1.21in) diameter hole that matches, and is aligned to, the bore of the gear.

Using 200W of power at a cut speed of 2.54m/min (100in/min), the hub was removed in a cycle time of 2.3 seconds per gear.

The cut edge exhibits slight charring due to the glass fill but has no effect on the finished product.
