Foshan CNC drilling and milling machine manufacturers talk about PCB circuit board processing CNC drilling and milling machines and CNC machine tools

　　CNC drilling machines and CNC milling machines are important equipment in PCB processing. They are not only costly and easy to operate, but also crucial for process setup and maintenance. The following text... Foshan High-Speed CNC Drilling and Milling Machine Manufacturer Let's talk about CNC drilling and milling machines and CNC machine tools in PCB processing.

　　Regarding CNC machine tools, in terms of pure technology and operation, Foshan high-speed CNC drilling and milling machine manufacturers generally consider the following aspects:

　　1. Rigidity and stability of the machine tool table

　　To ensure sufficient machine stability, many manufacturers avoid using marble as the bed material; some Japanese manufacturers use steel beds. This is because steel warps more than marble at different temperatures, making it less stable.

　　Compensation is implemented to address the precision loss caused by warping. Currently, most manufacturers use natural or artificial marble for the bed, and equipment with marble beds is recommended. Marble is routinely cleaned in daily life using detergents and water-based abrasives.

　　Cleaning. Please do not use alcohol. Wipe with a dry cloth after wiping, and wait until the moisture fully evaporates before use.

　　2. Speed and stability of the rotating axis:

　　Foshan High-Speed CNC Drilling and Milling Machine Manufacturer: Currently, there are two types of rotating axis systems used: rolling bearings with a maximum speed of 80,000 rpm, and air bearings with a maximum speed of 120,000 rpm. If the milling machine needs to use rolling bearings, drill chucks will also be purchased because of their superior longitudinal load capacity compared to air bearings.

　　The main areas of consideration are that some drill bits are difficult to replace and repair, some wear out quickly and become consumables with high replacement costs, and some require daily maintenance, wasting time. In addition, hinge presser feet are another example with unreasonable lifespan and design.

　　There is no seal between the spindle and the foot, the vacuum cleaner consumes a lot of energy, wasting energy on purchasing a vacuum cleaner or central vacuum system, and debris in the PCB holes may cause defects.

　　3. Iterative accuracy of movement and displacement:

　　An important point to consider during selection is that it cannot be judged by drawings or general operation. It needs to be tested after purchase to verify. Currently, equipment in factories can meet design standards, but it requires 1-2 years of precision operation.

　　Whether the degree is very stable, in this aspect, European-made machine tools perform better.

　　4. x, y, z-axis feed rate:

　　Currently Foshan High-Speed CNC Drilling and Milling Machine Manufacturer it is believed that the feed rate is generally 25m/minute for silk stepper motors at 25m/minute, and a high feed rate can increase production capacity by 20%~40%. The speed on the z-axis is affected by the drill bit and drill bit material.

　　The impact on productivity is not significant.

　　5. Mobile and fixed table equipment:

　　Mobile tabletops used to be mainly based on guide rails, but there are also those that use air flotation for tabletop movement. Air flotation tables are flexible and easy to maintain. The device for fixing circuit boards on the table is usually a pneumatic clamp, this type of clamp.

　　The design plays an important role in future equipment replacement. It generally does not wear easily, and when equipment does wear, it is one of the parts that wears severely. Wear replacement and adjustment are simple, including machine tool positioning accuracy adjustment (for milling machines). Template) Currently, many manufacturers offer automatic feeding devices. If there is no good equipment maintenance engineer, it is recommended not to choose. The use of automatic feeding devices is because the requirements for maintenance engineers are very high. Currently, circuit boards need to be drilled one at a time.

　　6. Maximum processing size:

　　Foshan High-Speed CNC Drilling and Milling Machine Manufacturer: Purchase the maximum processing size according to your needs. Currently, most machine tools can meet user needs. However, you can also manufacture test fixtures on some single-axis or 2-axis machine tools.

　　7. Operation and control system:

　　Now many machine tools are very familiar with the interface of the ordinary Windows operating system. Some use Chinese, which is relatively easy to learn and operate, but the disadvantage is that the stability is slightly worse due to computer viruses, and management is difficult. Some are industrial systems or

　　This system has the advantages of stability, low failure rate, and easy management. However, Foshan high-speed CNC drilling and milling machine manufacturers believe that the operation interface is all in English, and the operation is a bit slow. It is recommended to use the latter for technology and equipment maintenance.

　　8. Tool management system:

　　In the past, there were rarely more than 8 tool holders in machine tool tools. Currently, most CNC machine tools can install hundreds of drill bits. Some systems also have automatic drilling detection and diameter and length measurement and radial runout systems. Items to note when choosing.

　　Most CNC machine tools are located at the front end of the table. This design method has a disadvantage. For example, due to positioning problems, the processed circuit board can protrude, making all drill bits easy to include drill chucks. Partial drill chuck design layout.

　　This problem will not occur on the top of the machine tool, such as some Swiss-made machine tools. If the sensitivity of the detection mechanism is too high or too low, it is generally not good for the machine tool.

　　9. Selection of photometric system:

　　Currently Foshan High-Speed CNC Drilling and Milling Machine Manufacturer It is believed that the measurement systems of CNC machine tools mostly use scales as the measurement feedback system for position and accuracy, and the use of scales has higher system stability and resolution. The scale reading does not contact the scale, so the lifespan is extended.

　　Although it is long-term, in daily life, keep the equipment clean and minimize dust pollution.
