Bridge-type Stone Cutting Machine Daily Maintenance Guide

Bridge-type stone cutting machines are core equipment in the stone processing industry. The high-intensity, dusty, and humid working conditions place extremely high demands on the equipment's stability and lifespan. To ensure stable operation, extend service life, and improve production efficiency, standardized daily maintenance is required:

 

I. Safety Maintenance: Strengthen safety management and eliminate safety hazards. Bridge-type stone cutting machines are high-risk operating equipment. Improper operation can easily lead to various safety accidents. Therefore, daily safety maintenance must strictly adhere to standardized requirements, achieving routine and meticulous management, with a focus on the following requirements:

 

1. Ensure the equipment's grounding system is intact and reliable. Unauthorized plugging and unplugging of the power cord is strictly prohibited during operation to prevent electric shock accidents.

 

2. The work area must be kept clean and orderly. Unauthorized debris is strictly prohibited, and unauthorized personnel are strictly prohibited from entering the equipment's operating area to effectively avoid collisions, entanglement, and other safety risks.

 

3. Before starting the equipment, the integrity of the safety devices must be strictly checked. If an electrical fault is found, the main power supply to the equipment should be immediately cut off. Repair work while the equipment is energized is strictly prohibited.

 

4. Operators must be proficient in the equipment's professional operating procedures. They can only work after systematic training and passing the assessment. Any violations of operating procedures are strictly prohibited.

 

II. Equipment Cleaning: Standardized Cleaning Procedures Ensure Smooth Equipment Operation Bridge-type stone cutting machines are prone to accumulating debris, dust, and oil stains during long-term operation, affecting operational accuracy and accelerating component aging. Regular cleaning is the foundation of daily maintenance. Specific procedures are as follows:

 

1. Equipment Exterior Surface: After each day's work, use a clean, soft cloth to thoroughly wipe the equipment's exterior surface, completely removing oil stains and dust to prevent dirt from penetrating and corroding machine components.

 

2. Worktable and Transmission Components: Use a brush and air gun to meticulously clean stone chips and dust from the worktable crevices and transmission parts, preventing debris from clogging and affecting transmission accuracy and equipment operational stability.

 

3. Critical Components: Water nozzles, cutting blades, protective covers, and other areas prone to chip accumulation must be cleaned promptly after each day's work to prevent chip buildup and wear on components, ensuring optimal cutting results.

 

III. Lubrication and Maintenance: Standardized Lubrication Operations Extend Equipment Lifespan
Lubrication and maintenance are crucial for extending equipment lifespan. High-speed, heavy-load operation can easily lead to wear on core components. Proper lubrication can reduce wear and prevent malfunctions. Specific requirements are as follows:

 

1. Before starting the equipment, thoroughly lubricate the core transmission components such as the cutting blade shaft, wheel shaft, guide wheel, and gears, ensuring complete lubrication coverage.

 

2. During operation, replenish lubricating oil or grease promptly based on the equipment's operating load and the actual working environment. Pay special attention to easily worn parts such as the motor, cylinder, and slide rails, and prevent damage caused by dry friction.

 

IV. Quick Troubleshooting of Common Faults

1. Rough Cutting Surface, Chipping: Saw blade wear/mismatch, insufficient cooling, excessive speed, unstable plate fixing.

 

2. Large Dimensional Deviation: Debris in the guide rail, accuracy drift, loose saw blade, origin offset.

 

3. Abnormal Noise/Vibration: Insufficient lubrication, damaged bearings, loose nuts, guide rail jamming. 4. Water flow obstruction: clogged filter, water pump failure, bent pipes, clogged nozzles.
