Urethane Grinding

This is a guide roll mounted in the grinder after it has been ground and grooved. The work head or head stock is on the left side of the roll and the tail stock is on the right. The wheel head, this is where the grinding wheel mounts, in just visible behind the guide roll.

This is a square saw pulley or bricketeer pulley shown mounted in the grinder having just completed the grinding and grooving operations. This assembly has a diameter of 330 mm and a total length of 889.5 mm. Each pulley is approximately 133 mm apart and the groove spacing from one pulley to the next is 157.35 mm +/- 0.02 mm. This is achieved by mounting the pulleys on the main arbor then grinding then assembly as a whole.

This is a picture of one of the bricketeer pulleys or square saw pulleys during the process of grinding the grooves. On the left is the pulley assembly on the right is the grinding wheel and you can see the coolant flowing from the nozzles and being sprayed about by the grinding process.

This is an example of what a reconditioned guide roll looks like when it is ready to leave our facility.

Guide Roll Maintenance

One of the methods used to remove worn hydrel or spherical bearings from the end of the guide roll for replacement.

Spherical bearing after it has been polished or cleaned up, ready for inspection. The inspection process is completed through the use of gages provided by the saw manufacturer to determine if the guide roll will seat correctly in the saw during use. The condition of the bearing also plays a part in the quality of the finishes and concentricity’s during the grinding process.

These are samples of the new spherical and drive bushings.
