How to prevent bad (rough) cuts on my Jet 414500 Saw?
Bad rough cuts on your Jet Saw can occur if the blade speed is too high for the feed pressure; reduce both. Also, if the blade is too coarse, replace it with a finer blade.
Why is the blade twisting on my Jet 414500 Saw?
If your Jet Saw blade is twisting, it could be due to the blade binding in the cut. Try decreasing the feed pressure. Alternatively, the blade tension might be too high, so decrease the tension on the blade.
Why is there excessive blade breakage on my Jet Saw?
Excessive blade breakage in your Jet Saw can occur due to several reasons. The material might be loose in the vise, so ensure you clamp the work securely. The speed or feed could be incorrect; refer to a Machinist’s Handbook for appropriate settings. The teeth might be too coarse for the material; check the Machinist’s Handbook for the recommended blade type. Incorrect blade tension can also cause this issue; adjust the blade tension until it doesn't slip on the wheel. Make sure the motor is started before the saw blade contacts the workpiece. Adjust blade tracking if the blade rubs on the wheel flange, and adjust the guides if they are misaligned. Finally, cracking at the weld can be solved with a longer annealing cycle.
Why is the blade on my Jet 414500 dulling prematurely?
Premature blade dulling in your Jet Saw can be caused by several factors. Using a finer tooth blade might help. If the blade speed is too high, try lowering it. For hard spots or scale on the workpiece, increase feed pressure or reduce speed and increase feed pressure, respectively. If the material is work hardening, especially stainless steel, increase feed pressure by reducing spring tension. Ensure proper blade tension and avoid running the blade at idle in/on material.
How to fix bad (out-of-square) cuts on my Jet 414500 Saw?
Bad cuts (out-of-square) with your Jet Saw can stem from several factors. Start by decreasing the feed pressure if it's too fast. Ensure the guide bearings are properly adjusted to a clearance of 0.001 inch (0.002 inch maximum). Gradually increase blade tension if it's inadequate. Replace the blade if it's dull. Check and correct the blade speed. Also, ensure that the blade guide assembly and blade guide bearing assembly are tightened. Adjust blade tracking if the blade track is too far away from wheel flanges, and replace the guide bearing if worn.
Why is there excessive speed reducer noise or vibration in my Jet 414500?
Excessive noise or vibration from the speed reducer in your Jet Saw can be caused by a V-belt that is too tight. Reset the V-belt tension to resolve this issue.
Why is the blade on my Jet 414500 twisting?
If the blade on your Jet Saw is twisting, it could be binding in the cut. Decrease the feed pressure. Alternatively, the blade tension might be too high, so decrease the tension on the blade.
What causes unusual wear on the side or back of my Jet 414500 Saw blade?
Unusual wear on the side or back of your Jet Saw blade can be caused by worn blade guides, so replace them. Alternatively, the blade guide bearings may not be adjusted properly; adjust them. If the blade guide bearing bracket is loose, tighten it.
How to avoid rough cuts with my Jet 414500?
Rough cuts on your Jet Saw can be caused by the blade speed being too high for the feed pressure. Reduce both the blade speed and the feed pressure. Also, the blade might be too coarse, so replace it with a finer blade.
What to do if teeth are missing or ripped from my Jet 414500 Saw blade?
Missing or ripped teeth on your Jet Saw blade can occur due to several reasons. If the blade tooth pitch is too coarse for the workpiece, use a blade with a finer tooth pitch. If the feed is too slow or too fast, try increasing feed pressure and/or blade speed. Securely clamp the workpiece to prevent vibration. If the gullets are loading up with chips, use a blade with a coarse tooth pitch and reduce feed pressure, and brush the blade to remove chips.
