In the field of stone processing, the uniformity of the output directly impacts the quality and aesthetics of the product. During stone cutting, numerous detailed factors determine the final output. The following is an in-depth analysis of the key factors affecting the uniformity of stone output.

Blade Preparation and Usage

1. Blade Idling: New blades should idle for 10-20 minutes before first use, especially in high-temperature environments during summer. Water-assisted idling helps eliminate the impact of welded segments on the blade body, ensuring the intrinsic quality of the blade during high-speed rotation.

2. Stability of the Cutting Environment: The block size should be no less than 0.5 cubic meters and should be securely placed, with square wood pads underneath to ensure the stability of the block and the workbench. This prevents shaking or wobbling during the cutting process.

3. Relative Position of Blade and Block: The blade should maintain a 10-20mm distance from the block before cutting, and after cutting, a gap of 20-40mm should be left between the cut edge and the bottom of the block to prevent the blade from striking the block.

Precision Control of Cutting Parameters

1. Trial Cutting Considerations: Trial cutting should only commence after the blade has idled steadily. Avoid starting the blade when it is in contact with the block. The blade should not stop rotating during the cutting process.

2. Monitoring Block Stability: If any wobbling of the block is detected, stop cutting immediately. Resume work only after the block is securely fixed.

3. Blade Speed and Feed Rate: If the blade slows down significantly or gets stuck during cutting, this could be due to belt slippage, loose tensioning nuts, excessive cutting depth, or an overly fast feed rate. Timely adjustments are necessary.

4. Adaptation of Cutting Speed: The cutting speed should be adjusted according to the hardness and abrasiveness of the stone being processed. Different types of granite require specific blades, and it is advisable to consult the blade supplier for the most suitable product when necessary.

5. Appropriate Feed Rate: The feed rate should be based on the characteristics of the material being processed. Both excessively high and low feed rates can impact blade longevity and cutting efficiency.

6. Rational Cutting Depth: Different cutting depth strategies should be employed for stones of varying hardness. Medium-hard stones such as marble and limestone can be cut through in one pass, while harder and more abrasive stones like granite and sandstone should be cut in steps.

Optimization of Cutting Techniques

1. Choice of Cutting Direction: Cutting is referred to as forward cutting when the blade’s rotation direction is the same as the stone feed direction, and reverse cutting when they are opposite. Reverse cutting generates vertical forces that may require a reduction in cutting depth.

2. Comprehensive Consideration of Process Parameters: When selecting cutting techniques, factors such as stone hardness, cutting performance, blade life, and core life should be comprehensively considered to achieve high efficiency, quality, and longevity in the processing operation.

Conclusion

Stone cutting is not only a technical process but also an art. Every detail matters, from blade preparation to the adjustment of cutting parameters and process optimization. Through meticulous process management and continuous technological innovation, the uniformity of stone output can be significantly improved, enhancing product quality and market competitiveness in the stone processing industry.
