Description

This unit describes the outcomes required to level, tension, back-gauge, weld and replace teeth on wide band saw bladesGeneral workplace legislative and regulatory requirements apply to this unit; however there are no specific licensing or certification requirements at the time of publicationThis unit replaces FPISAW3220A Maintain wide band saw blades

Notes

Elements and Performance Criteria

1. Prepare for maintenance2. Assess saw condition

2.1. Applicable Occupational Health and Safety (OHS), environmental, legislative and organisational requirements relevant to maintaining wide band saw blades are identified and followed2.2. Work order is reviewed and checked with appropriate personnel2.3. Wide band and gang saws to be maintained are removed from the designated machinery2.4. Equipment is selected appropriate to work requirements and checked for operational effectiveness in line with manufacturer's recommendations2.5. Maintenance process is planned in line with site procedures and environmental requirements2.6. Communication with others is established and maintained in line with OHS requirements
2.7. Saws are handled safely without damage to teeth2.8. Foreign material built up on blade surfaces is cleaned for inspection2.9. Saw is inspected to assess condition of teeth and saw blade2.10. Teeth and tips requiring repair or replacement are checked and marked2.11. Saw is declared unserviceable where hazardous defects are found and disposed of in line with site procedures, manufacturer's recommendations and environmental requirements

3. Level, tension and back-gauge saw blade

3.1. Ridges or lumps across and along saw are assessed and matched on both sides of the blade3.2. Gauges and straight edges are used in both directions and monitored for accuracy3.3. Ridges or lumps are progressively removed through levelling and the use of stretcher rolls or levelling rolls to achieve flatness3.4. Levelling or rolling patterns are controlled to localise stresses to avoid spring-back and re-occurrence of defects3.5. Saw blade is checked against required curvature using a gauge to identify tensioning requirements3.6. Tension curvature is obtained across and along saw blade in line with required standard3.7. Alignment of saw back is checked against saw tolerances using a gauge and areas not conforming are rolled to obtain required tolerance

4. Repair teeth and blade cracks

4.1. Saw blade is placed in welding jig for applying heat and undertaking welding activities4.2. Weld line is marked to check amount of damaged tooth to be removed or crack to be repaired and selected to minimise stresses 4.3. Metal is removed to the proposed line, the metal edge is prepared for the welding process and cleaned free of burn marks4.4. Worn, broken or ground surface is prepared for metal build up or replacement by applying heat and pressure4.5. Teeth or cracked area is built up or replaced using compatible welding material and welding procedures that ensure specified metal penetration and density4.6. Weld run-off tabs are used to limit stress and hollows at edges of the saw blade4.7. Teeth or cracks are ground or filed to required shape, tolerance and pitch4.8. Saws where teeth, tips or blade cracks are damaged during the repair process and cannot be repaired are disposed of in line with site procedures, manufacturer's recommendations and environmental requirements4.9. Repair process and equipment faults are investigated, recorded and reported in line with site requirements
