Hello everyone, today by Longsheng technology to share with you about CNC precision parts machining tips, so that you can better master this skill, in modern manufacturing industry whether it is the production of automobiles, aircraft, or electronic equipment, CNC tools are needed to manufacture precision parts, in this blog, Longsheng Technology will introduce some basic skills of CNC precision parts machining, and how to improve the precision and quality of products by changing the machining process, hope to help you
So, what skills are there in cnc precision parts machining?
cnc precision parts machining skills
First of all, let’s look at the main steps in the machining process of CNC precision parts. In CNC precision parts machining, need to use CAD and CAM software to design and transform the product model, then use CNC tools for milling, turning, drilling and engraving operations, and finally finish the product machining. In this process, we need to pay attention to the following aspects:
- In the machining process of cnc precision parts, remove the jaws of the pliers and process two M4s. The two screw holes are flush with the pliers and 1.5mm thick copy the steel plate
- Riveted 0.8mm thick with aluminum head rivets and hard brass plate 3M4. Tighten 1 penetration screw 1 to the jaws to produce a strong and durable soft jaws. In this way, the parts can also be clamped, with exchangeability.
- In the process of cnc precision parts machining, it is inconvenient to use magnet to absorb small parts (cost). You can draw a piece of iron plate 2 under magnet 1. It can not only absorb many small parts, but also open the iron plate and automatically pour small parts into the collection box. It’s not enough to touch the heart, but it’s very practical.
- cnc precision parts machining in the belt disk drive, the belt disk often and the drive shaft skid, pivot using ~18mm drill series consistent, can produce absorbability anti-skid, waste utilization.
- In the process of cnc precision parts machining, when the hex wrench is short and impractical, the pipe with an inner diameter slightly higher than the wrench can be inserted into the slot from the milling groove and the development handle can be seen.
CNC precision parts machining materials
The key to CNC precision parts machining is to use high quality machining materials
CNC precision parts machining materials are a class of innovative materials. Due to its unique physical and chemical properties, they are widely used in CNC precision parts machining, including the following material types:
Metal materials: This is the most widely used CNC precision parts machining materials, its high mechanical strength, strong deformation ability, good corrosion resistance, good ductility, strong recyclability and other characteristics, so that it has a high application value in CNC precision parts machining. Common metal materials are aluminum alloy, stainless steel, copper and iron.
Non-metallic materials: Non-metallic materials with light, strong, corrosion resistance, insulation, cleaning, luster and other characteristics, is an effective way to replace metal materials. Common non-metallic materials include polymer materials, ceramic materials and composite materials.
Powder metallurgy materials: Powder metallurgy technology is one of the important ways to manufacture CNC precision parts. This material is characterized by small powder size, good dispersion, good porosity, good wear performance and high temperature resistance.
CNC precision parts machining materials
First, metal materials
Aluminium alloy
Aluminum alloy is a lightweight, high-strength metal used in aerospace, automotive and electronic equipment. Its advantages include good toughness, corrosion resistance, reliable machining performance and formability, and the inferiority point is low hardness, poor thermal stability.
Titanium alloy
Titanium alloy is a kind of high strength, low density metal material, often used in the manufacturing of aerospace, medical and chemical industries. Its advantages include high strength, corrosion resistance, fatigue resistance, lightweight and good molding performance, while its disadvantages are high price, difficult to process and form.
Magnesium alloy
Magnesium alloy is a kind of light weight, high strength metal material, often used in aerospace, automotive and electronic equipment. Its advantages include lighter than aluminum alloy, stronger than steel, good recyclability, low cost, and the weak point is easy to corrosion, poor plasticity, strong oxidation.
Two, non-metallic materials
Carbon fiber
Carbon fiber is a lightweight, high-strength nonmetallic material that is often used in the manufacturing of aerospace, sports equipment, medical equipment and other fields. Its advantages include very high specific strength, stiffness and fatigue resistance, good conductivity, high corrosion resistance, and the bad point is expensive, easy to brittleness, molding difficulty.
Ceramic material
Ceramic material is a kind of non-metallic material with high hardness, high strength and high wear resistance, which is often used in the manufacture of medical instruments, chemical reactors, sensors and other fields. Its advantages include corrosion resistance, high temperature stability, good insulation, strong biocompatibility, and the bad point is fragile, difficult to process and form, high price.
FAQ
CNC precision parts machining can achieve very high accuracy, up to the micron level depending on the specific application, which allows for more precise and consistent manufacturing.
CNC precision parts machining standards are usually set by the International Organization for Standardization (ISO). ISO standards specify the standard parameters used to manufacture various parts, such as size, shape, surface roughness, etc. The quality of CNC machining depends on the parameters and requirements of the machining process, including cutting speed, feed speed, depth, tool material and so on.
CNC precision parts machining has many advantages. First, it can achieve high precision and high efficiency production. CNC machines are capable of cutting, drilling, turning, milling and other operations at high speed, while ensuring the exact size and shape of the parts. Secondly, CNC technology can improve the reliability and stability of the production process. Each machining step is carried out under the control of the computer program, and the operation and maintenance of the machine are very simple. Finally, CNC technology provides greater flexibility and scalability, enabling manufacturers to produce parts in a variety of shapes and sizes.
