Hydraulic band sawing machine failure Daquan?
Screaming when sawing by band saw
Causes of failure: 1. The saw blade speed is too fast or the feed rate is too large. 2. The coolant is selected improperly or the ratio is incorrect. 3. The guide block is too tight. 4. There are hard spots in the material;
Maintenance methods: 1. Reduce the speed or feed rate. 2. Replace the coolant. 3. Adjust the gap between the guide blocks. 4. Rotate the workpiece to a certain angle and then cut again.
Band saw saw material skew
Causes of failure: 1. Improper selection of saw teeth 2. Improper adjustment of the guide arm and the work surface or jaws are not perpendicular to the table 3. The gap between the guide blocks is too large 4. The saw blade is not symmetrical 5. The saw band is not tensioned enough 6. The feed is too large ;
Maintenance method: 1. Choose a suitable saw band 2-3, re-adjust the gap between the guide arm and the guide block 4. Replace a suitable saw band 5, increase the tension 6, reduce the feed rate.
Band sawing machine saw the band boring car skid or interrupted cutting
Reasons for failure: 1. The feed is too large 2. The saw band is not tensioned enough;
Maintenance method: 1. Reduce the feed rate 2. Increase the tension.
Running belt when cutting by band saw
Cause of failure: wear of two saw wheels;
Repair method: replace the driven wheel.
Tooth when cutting by band saw
Causes of failure: 1. The workpiece is not clamped. 2. The feed rate is too large. 3. The saw tooth is too large. 4. The feed is uneven. 5. The saw blade is not straight and beats severely.
Maintenance method: 1. Re-clamping work 2. Reduce the feed rate 3. Use small serrations 4. Check the speed control valve lift cylinder 5. Re-welding the saw blade.
Band sawing machine breaks
Causes of failure: 1. The tension is too large 2. The weld is not firm 3. The work clamp is not tight 4. The saw blade is of poor quality 5. The feed is too large;
Maintenance method: 1. Reduce the tension 2. Re-welding 3. Clamp the workpiece 4. Replace the saw blade 5. Reduce the feed rate.
