I. Cutting Accuracy-Related Faults
1. Dimensional Deviation Exceeds Tolerance: Dimensional errors exceeding tolerance range after continuous cutting are often caused by worn feed screws or outdated tool compensation parameters.
2. Abnormal Cutting Quality: Uneven cut surfaces, numerous burrs, and tilting are generally caused by worn saw blades, spindle misalignment, or uneven worktable surfaces.
II. Tool and Feeding Faults
1. Rapid Tool Wear: Improper selection of cutting parameters, poor tool quality, and malfunctions in the lubrication and cooling system can lead to rapid tool wear, increasing production costs.
2. Inaccurate Feeding Positioning: Malfunctions in the feed motor, loose belts/chains, and misalignment of the positioning device can result in inconsistent cutting lengths, affecting finished product quality.
3. Blade Ridge Jam: Insufficient air pressure, damaged cylinders, damaged throttle valves, or obstruction by foreign objects can prevent the blade from rising properly after cutting.
III. Power and Mechanical Structure Faults
1. Motor Faults: Long-term overload, short circuits or open circuits in the windings, poor heat dissipation, and unstable voltage can cause the motor to malfunction and the equipment to stop operating.
2. Vibration and Abnormal Noise: Poor balance of the rotating wheel, excessive clearance between parts, and loose motor mounting can cause significant vibration; insufficient rigidity and inferior bearings can lead to excessive noise.
3. Excessive Saw Blade Swing: Improper saw blade installation, poor saw blade quality, and worn spindle bearings can cause saw blade swaying, and may even pose a safety hazard of saw blade breakage.
IV. Control System and Hydraulic Faults
1. Hydraulic System Faults: Hydraulic oil leaks, hydraulic pump malfunctions, and blocked or damaged hydraulic valves can cause abnormal tool feed and retraction movements.
2. Control System Faults: Controller program errors, sensor malfunctions, and aging wiring can lead to operational failures and the inability to perform automation functions properly.
3. No Oil Injection Fault: This is generally caused by the saw blade height adjustment nut being set too high; adjusting the nut position will resolve the issue.
