1、 The important position of chamfering and drawing machine in metal processing
In the field of metal processing, chamfering and wire drawing machines are like "precision masters", playing an irreplaceable key role. It is mainly used for chamfering the edges of metal workpieces, and can also complete the drawing process, giving the metal surface a unique texture and luster.
2、 Accuracy of chamfering function
Accurate angle control
The chamfering and drawing machine can accurately set the angle of chamfering. Whether it is the common 45 ° chamfer or other angles such as 30 ° and 60 ° according to specific design requirements, they can be achieved through the CNC system or precision mechanical adjustment device of the machine tool. For example, in mechanical manufacturing, precise chamfer angles (such as 15 °) can ensure smooth assembly of parts that require tight fitting, such as the connection between shafts and holes, and reduce stress concentration.
Compared with manual chamfering, the angle control accuracy of machine tools is higher. When manually chamfering, even experienced workers find it difficult to ensure that the chamfering angle of each workpiece is completely consistent. The chamfering and drawing machine can control the chamfering angle error of each workpiece within a very small range through pre programming or mechanical limiting, usually achieving precision of ± 0.1 ° or even higher.
Uniformity of chamfer size
This machine tool can ensure uniform height of chamfer dimensions. It processes at a stable feed rate and cutting depth according to the set parameters. For example, in furniture manufacturing, for chamfering the legs and feet of metal tables and chairs, machine tools can ensure that the chamfer width and depth of each leg are exactly the same, making the appearance of the product more beautiful and exquisite. This uniformity is particularly important for mass-produced metal products, as it can improve the overall quality and consistency of the product.
3、 Excellent performance of wire drawing technology
Texture consistency
Chamfering and wire drawing machines can create uniform and consistent wire drawing textures on metal surfaces. By controlling parameters such as the speed and feed rate of the drawing wheel, as well as the type of drawing material, it is possible to produce a drawing effect with uniform thickness and consistent direction. For example, in the processing of metal casings for electronic products, such as phone casings or laptop casings, uniform brushed textures can enhance the texture and aesthetics of the product, and provide consumers with a comfortable touch.
Compared to manual drawing, machine drawing can avoid problems such as uneven texture depth and disorderly direction caused by the instability of manual operation. When manually drawing, it is difficult to achieve complete consistency in the degree of force and drawing direction of the workers, while the machine tool can strictly follow the program instructions and stably output high-quality drawing effects.
Surface quality improvement
Using chamfering and drawing machines for drawing can effectively improve the surface quality of metals. During the drawing process, it can remove small defects on the metal surface, such as scratches, oxide layers, etc. Moreover, the machine tool can precisely control the drawing pressure to prevent excessive damage to the metal surface. For example, in the processing of automotive components, such as the surface wire drawing treatment of aluminum alloy wheels, it can not only enhance the aesthetics of the wheels, but also improve their corrosion resistance and extend their service life.
4、 Advantages of application in complex metal processing
Dealing with various metal materials
Chamfering and drawing machine tools can adapt to the processing of various metal materials. Whether it is common steel, aluminum, copper, stainless steel, etc., high-quality chamfering and drawing can be achieved by adjusting the machining parameters of the machine tool (such as cutting speed, tool selection, etc.). For example, for stainless steel materials with high hardness, machine tools can use hard alloy cutting tools to process at a appropriately reduced cutting speed, ensuring the effect of chamfering and drawing; For softer aluminum materials, high-speed cutting can be chosen to improve processing efficiency.
Complex shape processing capability
It also has the ability to handle complex shaped metal workpieces. For metal products with curves, surfaces, or irregular shapes, machine tools can achieve precise chamfering and drawing by equipping them with special tools, fixtures, and programming paths. For example, in the production of handicrafts, for some metal ornaments with complex shapes, chamfering and drawing machines can finely process them along their unique contours, making the details of the product more perfect and showcasing exquisite craftsmanship.
