Application Cases《Plasma cuttier for precision cutting of alloy steel in experimental process.》

1. Preparation

Equipment inspection: Make sure that the plasma cutting machine and its related accessories (such as power supply, gas pipeline, nozzle, etc.) are in good working condition, and check the control devices such as cutting current and gas pressure.

Material preparation: Select suitable precision alloy steel samples, which usually require materials with high hardness (such as tool steel, stainless steel, high-speed steel, etc.). The thickness, hardness, chemical composition, etc. of the sample should be clear.

Environmental preparation: The laboratory should have good ventilation facilities to avoid the accumulation of harmful gases. Experimenters should wear appropriate protective equipment, such as protective glasses, fireproof clothing, protective gloves, etc.

2. Parameter setting

According to the special needs of cutting precision alloy steel, set the following cutting parameters:

Cutting current: Precision cutting requires a smaller current to avoid overheating and overburning. Usually set a lower current to obtain a finer cut.

Gas type: For precision alloy steel, nitrogen or oxygen are commonly used gases. Nitrogen cutting has a cleaner effect, while oxygen helps to improve cutting efficiency, but may increase oxidation of the cut.

Gas pressure: The gas pressure needs to be adjusted according to the thickness and cutting requirements of the alloy steel. For precision cutting, a low and stable gas pressure is usually required to ensure a smooth cut.

Cutting speed: Set an appropriate cutting speed to avoid too fast cutting resulting in poor cutting quality or too slow cutting resulting in too much heat affected zone. Experimental adjustments need to be made according to the thickness and hardness of the material.

3. Safety measures

Wear protective equipment: Ensure that the operator wears comprehensive protective equipment, such as protective glasses, earmuffs, high temperature resistant gloves, etc.

Fire protection: Sparks and high temperatures may be generated during the cutting process. The surrounding area should be kept free of flammable materials and a fire extinguisher should be prepared.

4. Sample fixation and position adjustment

Fix the material: Fix the alloy steel sample on the cutting table to ensure its stability. The material fixing method should ensure that the vibration during the cutting process is minimal to avoid affecting the cutting accuracy.

Align the cutting path: Use equipment such as laser positioning or laser aligner to ensure that the cutting path is accurate.

5. Start cutting

Start the equipment: Start the plasma cutting machine and ensure that the parameters such as current, gas pressure, and cutting speed are correct.

Monitor the cutting process:

Stabilize the arc: Ensure that the plasma arc is stable to avoid unstable phenomena such as arc voltage fluctuations.

Precision cutting: Due to the high hardness of precision alloy steel, the flatness and quality of the cut must be ensured during the cutting process, and no overburning, melting or deformation will occur.

Observe the cutting effect: Continuously observe the cutting effect to ensure that the cut is clean, burr-free, and without excessive heat-affected zone.

6. Inspection and evaluation

Cutting quality inspection:

Check the flatness and smoothness of the cut and evaluate the cutting accuracy.

Measure the width, depth, and accuracy of the cut, especially for micro-sized cuts, to ensure that the accuracy requirements of the experiment are met.

Check the heat-affected zone (HAZ) around the cut to see if there is excessive hardening or embrittlement.

Surface quality inspection:

Use a microscope or other surface analysis equipment to check the quality of the cut surface to ensure that there is no obvious oxide layer or other defects.

If there is residue, slag or burrs, it can be cleaned by mechanical grinding, ultrasonic cleaning, etc.

7. Post-processing

Cleaning the cut: Remove slag and oxides that may appear during the cutting process. Common methods include air flow cleaning, solvent cleaning, etc.

Deburring: Remove burrs around the cut by mechanical grinding, polishing, etc. to ensure the smoothness and precision of the cut.

Deoxidation: For cuts with severe oxidation, use chemical methods or electrolysis to remove the oxide layer.

8. Result analysis and adjustment

Record parameters: Record the current, gas type, pressure, cutting speed and other parameters used in the cutting process.

Adjust parameters: According to the experimental results, adjust the parameters of the cutting machine to improve the cutting quality. For example, you can reduce the current, adjust the gas pressure, optimize the cutting path, etc.

Comparison and evaluation: Compare the experimental results with the expected cutting accuracy, and evaluate the performance and cutting quality of the equipment to determine whether it meets the precision cutting requirements.

9. Equipment maintenance and care

Clean the cutting head: Clean the cutting head, nozzle and other parts after each experiment to prevent carbon deposits or impurities generated by combustion from clogging the nozzle.

Check the electrode and nozzle: Regularly check the wear of the electrode and nozzle, and replace them in time to ensure cutting accuracy.
