Drilling is a basic method of hole processing, and it accounts for a large proportion in Dongguan CNC precision processing plants. The tools used for drilling are divided into shoulder drills and twist drills, which can process holes on solid materials. Due to the large cutting load, poor tool stiffness and disadvantages in drilling. The following problems often arise during drilling: the drill bit is easily biased, causing deviation of the hole axis and linearity error; the hole diameter is easily expanded; the hole wall is rough; and the axial force is large during drilling. Therefore, drill bits can only be used to process holes with low accuracy requirements, or to roughly process holes with high accuracy requirements. The general dimensional accuracy of drilling is T11 to T14, and the surface roughness is Ra60 to 12.5m. In order to ensure the processing quality, the following measures are adopted in the process: (1) Process the end face before drilling to ensure that the end face is perpendicular to the drill bit to prevent deviation. (2) When sharpening the tool, try to make the two main cutting edges of the drill bit symmetrical so that the radial cutting force generated by the two cutting edges is consistent. (3 Read More

The traditional production management system in precision parts processing generally supplies parts to the next process in the previous process, and adopts the method of increasing product reserves to cope with problems such as imbalances and accidents in production and changes in demand. The disadvantage of this method is that regardless of whether the parts required for the next process are used up, the parts will be sent to the next process after being produced, which can easily cause the next process to be accumulated on the product. In order to overcome the above shortcomings, the on-time production system came into being. The key point of on-time production in precision parts processing is on-time, that is, only when necessary, produce necessary products (parts, parts, finished products) in the necessary quantity. Its goal is to minimize the reserves of products in-process, thereby maximizing the saving of funds, making the most of the use of manpower and equipment, improving efficiency and reducing costs. At the same time, the system is flexible. In terms of human factors, production workers are required to have high enthusiasm and great initiative. Read More

In precision parts processing, on-time production is done by using Kanban as a tool to connect the upper and lower processes to form flow operations and performing on-time production. Kanban boards are also called subpoena cards. They are pre-filled with the names, numbers, materials, production quantities, production time, weight, processing location, transportation location, transportation time, station equipment and capacity of the parts. project. Each board is fixed to represent a certain number of parts, such as one piece, or one piece of ten pieces, etc. The board must be circulated with the physical objects. In precision parts processing, Kanban management is to pass operation instructions within the enterprise and between the enterprise and collaborative enterprises in accordance with the requirements specified on the Kanban. That is, to use the Kanban to order and collect goods from the top process in turn, so as to make each production process. All of them get the necessary quantity of necessary products (or parts) at the necessary time to achieve on-time production, thereby eliminating unnecessary in-production products and completely eliminating waste of this Read More

Generally, CNC precision machining usually refers to computer digitally controlled precision machining, CNC machining lathes, CNC machining milling machines, CNC machining boring and milling machines, etc. CNC precision machining tools are controlled by our skilled staff with the help of complex digital systems. CNC or computer digital control allows extremely special control of positioning, speed, coordination, feed rate and other precision aspects of the manufacturing process of a particular part or object. The CNC machine of the automatic pallet shuttle reduces the cycle time of manufacturing parts, thereby increasing our customers' throughput.

People should conduct an appearance check on this first batch of aluminum alloy die-casting parts with poor shortcomings to see if the surface layer of the casting parts has caused a rough surface in some parts. The reasons for friction and gap corrosion caused by the production and processing of aluminum alloy die castings are given: (1) The position and appearance of the inner runner caused by the die casting mold are not good; (2) The aluminum alloy profile liquid at the inner runner caused by the forging standard Water cooling is insufficient in severely eroded locations. The ways to deal with and avoid corrosion of friction gaps are: (1) Improve the location and orientation of the inner runner and the place where the internal water is improperly poured; (2) Improve the water cooling standards, which is very important to improve the strong position of metal material liquid erosion; (3) Corrosion of the gaps to enhance the building paint; (4) Adjust the water flow rate of the aluminum alloy liquid so that it does not cause air pockets (5) Remove aluminum alloy adherents on the abrasives. The production and processing of aluminum alloy die castings actually cause friction gap corrosion! Don’t worry, follow the left and right methods Read More

CNC machining, also known as CNC machining, must be mass-produced after the first piece is trial-cut, but the first piece is qualified does not mean that the whole batch of parts will be qualified, because during the processing process, it depends on the different processing materials. It will cause wear of the tool, soft processing materials, less wear of the tool, hard processing materials, and fast wear of the tool. Therefore, during the processing process, you must conduct frequent inspections, increase and decrease the tool compensation value in time to ensure the qualified parts. Because CNC machining is programmed and controlled by computers, CNC machining has the advantages of stable processing quality, high processing accuracy, high repeatability accuracy, complex model processing, and high processing efficiency. In the actual processing process, human factors and operating experience will greatly affect the final processing quality. The design of molds and parts is becoming more and more complex, the accuracy requirements are getting higher and higher, and the delivery time is getting shorter and shorter. Generally, there are 20 to 30 precision inspection items in CNC machining centers, but their most characteristic ones are Read More

Dongguan CNC processing manufacturers are developing towards a high-speed and efficient road. This includes the speed control of Dongguan CNC machining. If you want to make full use of the effective working stroke, it is necessary to accelerate the moving parts to the high-speed stroke in a very short time and stop accurately during the high-speed stroke. This is why the speed control of Dongguan CNC processing is necessary. Based on the open control idea, we propose a method that can automatically accelerate and decelerate the movement of CNC machine tools according to any curve. This method will push automatic acceleration and deceleration control from the traditional fixed mode to the new flexible mode, exploring a new way to effectively improve the dynamic performance of CNC machine tools. 1. Flexible acceleration and deceleration control is generally implemented by the system program directly to realize specific automatic speed control functions. In this way, the system acceleration and deceleration characteristics must be changed or the addition and subtraction control must be used to modify the CNC program, so ordinary users cannot press themselves Read More
