Small Diameter Single-Edge Milling Cutter

Zhongyeda's small diameter single-edge milling cutter is characterized by its small diameter, which enables it to perform fine processing in a small space. At the same time, the durable small-diameter single-edge design makes the cutting force more concentrated, and can efficiently complete the processing task in a short time. In addition, the small diameter single-edge milling cutter has a faster cutting speed and can better protect the surface of the workpiece to avoid burrs, thereby ensuring that the processed workpiece has high precision and surface quality.

During the manufacturing process, small diameter single-edge milling cutters need to go through a strict design and processing process. From the selection of raw materials, forging or casting blanks, to rough processing, grinding, sharpening, coating treatment and other steps, each link requires fine operation to ensure the quality and performance of the final product. Especially in the sharpening process, special sharpening equipment is required to finely grind the cutting edge of the milling cutter to ensure that the sharpness and geometry of the cutting edge meet the processing requirements.

The application range of small diameter single-edge milling cutter is very wide. In the machinery manufacturing industry, it can be used for finishing parts and mold making; in the aerospace industry, it can be used for grinding of precision parts and high-precision machine tools; in the automotive manufacturing industry, it can be used for cutting or drilling operations in the production process of aluminum alloy parts. In addition, in the fields of electronic information, biomedicine, optical instruments, etc., small diameter single-edge milling cutter also plays an irreplaceable role.

Features

1. Cutting and chip removal: small diameter single-edge milling cutter has good cutting capacity and chip removal performance. Since there is only one blade, the chips can be discharged more smoothly during the cutting process, reducing the accumulation of chips in the processing area, thereby reducing the problems of scratches on the processing surface and increased tool wear caused by chip accumulation8.

2. Processing accuracy: small diameter single-edge milling cutter can achieve high-precision processing. The blade diameter of small diameter single-edge milling cutter is small, and very fine details and contours can be processed. It is suitable for engraving tasks with high precision requirements, such as engraving of small crafts and precision molds.

3. Surface quality: The surface brightness of a small diameter single-edge milling cutter is better. When a single blade is cutting, the cutting force on the material surface is more uniform. Unlike a multi-edge milling cutter, there may be slight undulations or knife marks on the surface due to the cutting difference between the blades, so a smooth processing surface can be obtained.

4. Tool rigidity: Compared with large-diameter tools, small diameter single-edge milling cutters have relatively low tool rigidity and are more prone to deformation and vibration during cutting, especially when the cutting depth is large or the cutting force is strong. This requires reasonable selection of cutting parameters when using to avoid excessive deformation or damage of the tool.

5. Cutting efficiency: The cutting efficiency of a small diameter single-edge milling cutter is relatively low, because at the same speed, only one blade is involved in cutting, and it takes longer to complete the same processing task than a double-edge or multi-edge milling cutter.

Application scenarios

1. Acrylic processing: small diameter single-edge milling cutters are often used for cutting and engraving acrylic materials. They can achieve smokeless, odorless, fast and efficient processing effects. The special manufacturing process can ensure that there is no cracking when processing acrylic, the knife marks are extremely fine or even no knife marks, and the surface is smooth and flat.

2. PVC material processing: It also has good performance in engraving and cutting PVC materials, and can process various shapes and patterns to meet different design requirements.

3. Wood processing: It can be used for fine processing of cork, thin wood boards, etc., such as making small wood carving crafts, detailed engraving of wooden models, etc., and can engrave delicate textures and exquisite patterns.

4. Small mold manufacturing: In the manufacturing process of small molds, small diameter single-edge milling cutters can be used to process the mold cavity, core and other parts of the mold, which can accurately shape the shape and size of the mold and ensure the accuracy and quality of the mold.

5. Electronic product shell engraving: suitable for engraving on electronic product shells, such as mobile phone shells, tablet computer shells, etc., which can engrave brand logos, patterns, texts, etc., to enhance the appearance texture and personalization of the product.

Selection considerations

1. Tool diameter: Select the appropriate tool diameter according to the size and shape of the workpiece and the fineness of the engraving. The smaller the diameter, the finer the details that can be processed, but the rigidity and durability of the tool will also be reduced accordingly7.

2. Tool length: The blade length should be longer than the thickness of the cutting body to ensure that the workpiece can be completely cut. For metal cutting, it is generally recommended that the blade length be within 4 times the blade diameter. For example, for a 3mm diameter blade, it is appropriate to choose a blade length within 12mm3.

3. Tool material: Common materials include tungsten steel, high-speed steel, cemented carbide, etc. small diameter single-edge milling cutters made of tungsten steel have higher hardness and wear resistance, and are suitable for processing materials with higher hardness; high-speed steel milling cutters have better toughness and are relatively cheap, and are suitable for processing materials with lower hardness.

4. Machine tool performance matching: Consider the performance of the engraving machine, such as speed, power, precision, etc., to see if it matches the small diameter single-edge milling cutter. If the speed of the engraving machine is low, the advantage of the high speed of the small diameter single-edge milling cutter may not be fully utilized; and if the power is insufficient, problems such as tool jamming and uneven cutting may occur during the cutting process.
