Application
This unit of competency describes the outcomes required to prepare the band mill, fit special grinders, grind the wheel profile and re-assemble the band mill in readiness for return of bandsaws and wide bandsaws to service. Work is completed in a forest and wood products factory setting.
The unit applies to Sawdoctor, Saw Repairer.
No licensing, legislative, regulatory, or certification requirements apply to this unit at the time of publication.
Elements and Performance Criteria
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the range of conditions. |
1. Prepare for reconditioning | 1.1 Review work order and where required check with appropriate personnel. 1.2 Select appropriate repair, maintenance and personal protective equipment and check for operational effectiveness in line with manufacturer's recommendations. 1.3 Plan reconditioning process in line with work order. |
2. Fit and grind wheel profile | 2.1 Follow organisational safety procedures throughout all maintenance and repair processes. 2.2 Inspect and measure wheel to identify wear and grinding method. 2.3 Service, fit and align wheel grinder to wheel and band mill in line with manufacturer's instructions and recommended tolerances. 2.4 Make trial cut to check and further align grinder. 2.5 Grind wheel to remove all wear, ensuring face is not hollow. 2.6 Control grinding feeds to obtain required wheel profile and finish. 2.7 Measure wheel to ensure diameter of back and front edges are equivalent. 2.8 Measure wheel profile to ensure grinding has achieved required profile. |
3. Reassemble band mill wheel | 3.1 Remove grinder and base plate from band mill when grinding is complete. 3.2 Reassemble band mill components to manufacturer's instructions. 3.3 Set up band saw on mill to specified alignment. 3.4 Test band saw and mill to ensure correct operation. 3.5 Remove isolation padlocks or tags at completion of work in line with safety procedures. 3.6 Dispose of unserviceable wheels in line with organisational procedures and environmental protection practices. 3.7 Identify routine processing and equipment faults and resolve or report to appropriate personnel. |
