Why is the production efficiency of the same tool-tool several times different? The conclusion is that the lighting used for CNC machine tools are not suitable, which considerably reduces the production efficiency of CNC machine tools. The following introduces the reasonable selection and application of the CNC machine lights.
How to improve the rate of use of CNC machine tools? Thanks to technical analysis, the use of lighting is very relevant. According to incomplete statistics, the proportion of unreasonable lighting used by national companies in CNC machine tools is as high as more than 50%. At the end of 2018, Chinese CNC machine tools had almost a million units, which means that more than 500,000 CNC machine tools had “incompetent” due to the unreasonable selection of devices or the poor application; Selection and application of CNC Machine Tool lighting because it contains considerable potential economic advantages.
Production cycle of small lots ﹦ Production (preparation / wait) Time + room processing time given that “room processing time” in the production of small lots is very short, the duration of “production time (Preparation / waiting) “has a crucial impact on treatment to bike. . To improve the efficiency of production, it is necessary to find ways to shorten the production time (preparation / expectation).
1. Here are three categories of CNC Machine Tool lighting that can be priority in the production of small lots:
Combined luminaire
The combined lights are also called “construction block accessories”. Processing requirements. Since the combined lights save time for the design and manufacture of special lighting, they considerably shorten the preparation time for production, thus effectively shortening the production cycle of small lots, that is to say the improvement of production efficiency. In addition, the combined luminaire also has the advantages of high positioning accuracy, great flexibility of tightening, a cycle and reuse, energy saving and manufacturing of materials and low use costs. Consequently, the treatment of small lots, especially when the shape of the product is relatively complex, the use of combined lights can be priority.
Precision combination of flat food pliers
Precision combined with the mouth is actually “combination pieces” in combined devices. Precision -combined oriental pliers have the advantages of a quick installation (disassembly), fast tightening, etc., so that they can shorten production preparation time and improve the production efficiency of small lots. Currently, the clamping range of flat mouthpashes commonly used abroad is generally less than 1000 mm, and the tightening force is generally less than 5000 kgf.
Brilliant luminaire base
The bases of brilliant lighting is not widely used in China, but they are widely used in developed countries in the industrial field such as Europe and the United States. It is in fact a fine white of the base of the luminaire which was finished, and the component positioning surface and the machine positioning connection part and the lights of the light have been completed. Users can treat and make special lights by themselves according to their real needs. It should be noted that the combined precision of the flat mouth mentioned here is not old -fashioned computers with visitors. Not suitable for use in CNC machine tools and machining centers. The combined precision of flat mouthpieces mentioned here is a series of new flat mouthpieces designed in developed countries in the industrial field such as Europe and the United States. has great flexibility of tightening, high positioning precision and fast tightening.
Availability of the permanent electrical magnet
Permanent electric lights are a new type of lighting designed using new permanent loving materials such as neodymical iron boron as a magnetic source and using modern magnetic circuit principles. A large number of machining practices have shown that electrical permanent loving lights can considerably improve the complete treatment efficiency of CNC machine tools and machining centers. The clamping and relaxation process of the permanent electric light takes only about 1 second, which considerably shortens the time of tightening; Consequently, it is therefore important to the conventional machine-tools, the tightening range of permanent electric accessories is greater, which is conducive to the complete use of the workbench and the treatment of CNC machine tools and Improving the complete treatment efficiency of CNC machines tools. The suction force of the permanent electric luminaire is generally 15 ~ 18 kgf / cm2, it is therefore necessary to ensure that the suction force (climbing force) is sufficient to withstand the cutting force. That is to say that the clamping force should not be less than 450 kgf.
2. CNC Machine Tools Fixtures adapted to the processing of important lots
Large treatment cycle by lots = treatment of waiting time + part of the part of the part + production time production time “treatment of waiting time” mainly includes the time of tightening of the part and replacement of the tool . The “Tightening time of the room” of traditional lighting lights of manual machines can reach 10 to 30% of the large -scale treatment cycle. Exploitation of the potential “machine-tool lights. Therefore, it is advisable to use special lights for quick positioning and fast tightening (loosening) for large-scale treatment.
Hydraulic / pneumatic pliers
The hydraulic / pneumatic pliers are special lights that use hydraulic pressure or pneumatic pressure as a power source, and use hydraulic components or pneumatic components to position, support and compress the part. The hydraulic / pneumatic pliers can precisely and quickly determine the mutual position between the part and the machine and the tool. Save the tightening and release of the room. The above advantages of hydraulic / pneumatic pliers make them particularly suitable for use in CNC machine tools, machining centers and flexible production lines, and are particularly suitable for large-scale treatment.
Availability of the permanent electrical magnet
The permanent electric lighting has the advantages of fast tightening, multi-station, single tightening, can be treated on several sides, stable and reliable tightening, energy saving and environmentally friendly and automatic control. Compared to the conventional lighting lights, permanent electric accessories can considerably shorten tightening time, reduce the number of tightening time and improve tightening efficiency. .
Brilliant luminaire base
The brilliant luminaire base can effectively shorten the manufacturing cycle for special lights and reduce the production time for production, generally shortening the mass production cycle and improving production efficiency; Therefore, the brilliant luminaire base is particularly suitable for large -scale production with tight cycles.
Use lighting reasonably to press the potential of the equipment
Experience shows that in order to improve the treatment efficiency of CNC machine tools, it is not enough to simply “select the CNC to good” machine devices “, and you must also work hard to” use “CNC Tools .
3. Here are three commonly used methods:
Multi-station method
The basic principle of the Multi-Station method: by tightening several parts at the same time, the aim of shortening the unit’s tightening time and the extension of the knife has an effective cutting time. A multi-installation light is a luminaire that has several positioning tightening positions. With the development of CNC machine tools and the need for users to improve production efficiency, there are more and more multi-end lighting applications. The multi-stations design becomes more and more common in the structural design of hydraulic / pneumatic pliers, combined pliers, permanent electric pliers and combined flat caps.
Use of the group
The use of the same several lights on the same established can also reach the “multi-station” tightening objective. The devices involved in this method must generally undergo a “standard design and high precision manufacturing”, otherwise it will be difficult to meet the requirements of the treatment of CNC machines. The group’s use method can make complete use of the CNC Machine Tool race, which is conducive to balanced wear of the machine-tool transmission parts; Also used in combination to obtain a tightening of large -scale parts.
Local quick change method
The local rapid change method consists in quickly modifying the function or the use of the luminaire by quickly replacing the local parts of the CNC machine (positioning elements, tightening elements, tools and guide elements ). For example: rapid change of the pliers with combined flat, the tightening function can be changed by quickly changing the jaws, such as the passage of tightening squares to tightening rod materials; as from manual tightening to hydraulic tightening. The local quick change method considerably shortens the time to replace and adjust the lights, and has obvious advantages in the production of small lots.
