SS Capillary Tube Cutting Methods & Safety

Introduction: As an important material in modern industrial production, stainless steel capillary tubes are widely used in electronics, medicine, chemical industry, and other fields. Their excellent properties and stable quality make them favored by many enterprises. However, cutting stainless steel capillary tubes is a technically demanding task. This article will provide a detailed introduction to the cutting methods and precautions for stainless steel capillary tubes.

I. Cutting Methods for Stainless Steel Capillary Tubes

1. Mechanical Cutting

Mechanical cutting is a common method for cutting stainless steel capillary tubes, including sawing, turning, and shearing. Sawing and turning are suitable for stainless steel capillary tubes with diameters ranging from a few millimeters to tens of millimeters, while shearing is mainly used for larger diameter tubes. The advantage of mechanical cutting is simple equipment and easy operation, but the disadvantage is slow cutting speed and large surface roughness of the cut.

2. Laser Cutting

Laser cutting is a high-precision and high-speed cutting method suitable for various materials and thicknesses of stainless steel capillary tubes. In the laser cutting process, the laser beam locally irradiates the capillary tube, causing the material to melt and be blown away by high-speed airflow to form a cut. The advantages of laser cutting are smooth cuts, high precision, and fast speed, but the disadvantage is high equipment cost and high requirements for operators.

3. Plasma Cutting

Plasma cutting uses the high-temperature action of the plasma arc to melt and blow away the stainless steel capillary tube, forming a cut. Plasma cutting is suitable for cutting medium-thick stainless steel capillary tubes, with cutting speed and precision介于 laser cutting and mechanical cutting. The advantage of plasma cutting is relatively low equipment cost and simple operation, but the disadvantage is that the odor and dust generated during cutting are harmful to the human body.

II. Precautions for Cutting Stainless Steel Capillary Tubes

1. Preparation Before Cutting

Before cutting stainless steel capillary tubes, it is necessary to prepare the relevant equipment and working environment. For mechanical cutting, check the condition of saw blades, cutting tools, etc. to avoid affecting the cutting quality; for laser cutting and plasma cutting, check whether the equipment is running normally and whether the gas source and power supply are stable.

2. Control of Cutting Speed

Different cutting methods have optimal cutting speeds, which are too high or too low will affect the cutting quality and effect. Cutting speed too high may lead to insufficient melting of the cut, causing welding; cutting speed too low will make the cut too much melted, resulting in material waste. Therefore, during the cutting process, adjust the cutting speed appropriately according to the material, diameter, and cutting method of the capillary tube.

3. Treatment of Cutting Surface

After cutting, the surface of the stainless steel capillary tube is often rough and requires subsequent treatment. For applications with high requirements, methods such as grinding and polishing can be used to treat the cutting surface to achieve the desired smoothness and finish.

4. Safety Precautions During Cutting

During the cutting of stainless steel capillary tubes, dust, heat, and noise are generated, which can affect the health of the operator. Therefore, during the cutting process, wear protective gear such as dust masks, safety goggles, and earplugs to ensure safety.

Summary: There are various cutting methods for stainless steel capillary tubes, including mechanical cutting, laser cutting, and plasma cutting. In actual cutting processes, choose the appropriate cutting method according to the material, diameter, and application scenario of the capillary tube. At the same time, pay attention to safety precautions and cutting surface treatment to ensure cutting quality and effects.
