Vertical Machining Center
The main user level of the vertical machining center is headed by the optimistic auto parts industry, as well as mold, aircraft, medical equipment, IT, optical equipment and other industries. In the aircraft industry, because most of the processed parts are multi-variety and small-volume products, there is a potential demand for vertical machining centers dominated by five-axis processing machines. In the future, industries such as electronic components, precision machine components, and semiconductor molds will also have potential demand.
All manufacturers are paying close attention to the development of five-axis machining machines in the aircraft, molds, semiconductors and other industries where demand is expected to expand. In stark contrast to the vertical machining centers that used to produce general-purpose parts a few years ago, the equipment solutions that focus on processing molds continue to emerge from manufacturers, which makes it clear that high-speed, high-efficiency, high The demand for grade processing is increasing.
For high-precision machining, some manufacturers pay more attention to the development of models for heavy-duty cutting materials. At the same time, composite processing technology aimed at reducing workpiece replacement time and centralized processes is also constantly innovating. In order to further improve the efficiency, some manufacturers are trying to add 1~2 axes to the control axis of the vertical machining center to form a 5-axis control, so that the workpieces with complex shapes and free-form surfaces can be loaded once. .
In terms of product development, due to the stricter requirements of users, we have to pursue high-performance technologies while maintaining low prices. As new technologies are being developed that are accelerating to meet environmental requirements, there is a greater need for equipment that can be sized and numbered to form flexible wire structures.
Dry cutting is now under development, as has been the case with dry processing systems that use high purity nitrogen to control the change in accuracy with oxidation. At the same time, in order to improve the working environment and improve economic efficiency, the handling of chips is also easy to recycle.
Horizontal machining center
Because the processing surface is vertical, the horizontal machining center is easy to fall off, which is more suitable for long time unmanned operation. Because of the modular structure, it can be imported into the most appropriate system in a short time. Because of its long unmanned operation time, it is more effective in terms of cost and cost than a single machine.
From the perspective of user demand, the requirements for horizontal machining centers are more apt to adapt to the production of multiple varieties and small batches, requiring processing equipment to flexibly adapt to changes in production-type machining parts caused by process concentration. Now that equipment investment by automakers is on the rise, demand is expected to expand further. In addition, due to the fundamental changes in the understanding of product manufacturing and the perception of the production system, the new production system derived from this may create demand for small machines that can form flexible wires.
While pursuing high-speed and high-precision, the manufacturers who started to produce the above models are still working hard on how to make the body compact and cost-controlled. That is to say, the development of such products focuses on the miniaturization of the body and the adaptation to the formation of a flexible line system.
From the perspective of technological development trends, it is aimed at improving the spindle speed, feed rate, precision, and corresponding heat displacement and modularization. Among them, high-speed research on the basic issues of machine tools has continued to yield results.
Since the increase of the feed rate is directly related to the processing time of the product, in order to improve the production efficiency, in the high-speed feed technology, the type of the drive device using the linear motor is increasing. At the same time, some manufacturers are developing high-speed horizontal machining centers that do not use linear motors, use feed shafts with large lead ball screws, feed acceleration of 1.5G~2G, and fast feed speed of 120 mm/min. The double-sided restraint tool is used on the main shaft, the spindle speed is 20,000 r/min, and the rapid feed speed is 60 m/min to minimize the non-cutting time of repeated positioning and knife-to-knife. In order to solve the thermal displacement effect caused by the speed increase and prevent the accuracy from deteriorating, a separate correction device, a spindle cooling structure, a cooling device, and the like are generally used.
CNC vertical lathe
Vertical lathes suitable for machining large diameter and large tonnage outer cylindrical workpieces are also used in various industries. Due to the limitations of its market, the products reflect the user's intention to a large extent, and many of them are delivered and used in the form of special machines. This is also the reason why users and manufacturers form close contact.
Recently, the demand for vertical lathes for construction machinery manufacturers that are optimistic about China's exports is impressive, and the ordering of the shipbuilding industry seems to be coming to an end. Since last year, CNC lathe manufacturers are looking forward to ordering heavy machinery industries with relatively active investment in aircraft, high-performance generators, and wind turbines.
Due to the increasing requirements in terms of delivery time, quality and price, some small and medium-sized equipment users prefer a compound processing machine that can be loaded and can be processed in a variety of ways in order to shorten the production cycle of the product.
The demand for semi-dry processing is also increasing in consideration of environmental protection requirements. According to the requirements of such users, OM production has developed a method of industry-university collaboration to develop a semi-dry processing technology using gasification heat, and has strengthened energy saving measures. Controls the use of electricity.
Nowadays, the demand for small-sized CNC vertical lathes with improved versatility and low price is still expanding. At the same time, like horizontal CNC lathes, the development of functional multi-functional machines with processing center awareness is active. For example, with the improvement of the requirements for the processing of complex shaped workpieces, the processing functions of the vertical lathe function plus the spinning, tapping, twisting and the like are also being developed.
Due to the configuration of the C-axis, different composite machining can also be performed by one-time loading. In addition, in addition to the cutting, and the double-sided ATC method using a single tool, a number of process intensive products that can be recutted are also seen in the milling function.
