The mechanical technology and tool selection determine the efficiency of the cutting process. The traditional manual machine relies on the teacher's father's operation. The working time of 8 hours a day is about 1/3 time in the loading and unloading, 1/3 time in the processing program, 1 / 3 Time is in the process of feeding, retracting and changing the tool. The actual working time with the capacity value may be less than 30 minutes. Therefore, in order to effectively improve the production technology, the machine factory will eliminate the manual machine and develop the NC machine.
NC mechanical equipment is input by instruction code, which speeds up the processing time of manual stagnation. However, there is no strong improvement in the planning and confirmation of the instruction and input instructions. Over time, the market has introduced CNC computer automatic machine equipment. The humanized operation of program input or graphic style makes the processing setting simple and simple, and promotes the mechanical industry manufacturing process to enter the fully automatic stage, and constantly tries to increase the existing processing efficiency. For example, in order to save the tool change time due to the tool change time, the tool change speed is reduced from 5 seconds to 4 seconds, 3 seconds, and more and more fast, but these are the techniques that the machinery factory has done to improve the processing efficiency. progress.
Cutting technology: production efficiency determines market competitiveness. The impact of cutting tool efficiency on cutting efficiency can not be underestimated. Even for machines with a speed of more than 3000 rpm, if only the cutting tool with a speed of 1,000 rpm is used, no matter the production efficiency is reduced. The quality of processed products will also be questioned, so while the machine is constantly being promoted, the tool manufacturers are also enriching the technology. If it is necessary to clarify whether it is a tool first, or to promote the industry to a higher level of technology, it is like Chicken raw eggs or egg raw chickens are difficult to distinguish, and the two impose pressure on each other's quality improvement, but in the end they will all aim to improve production efficiency.
The tool manufacturer continuously develops special tools that combine a variety of cutting functions on one tool, aiming at one-time machining, which can be used for simple machining procedures, saving tool change time, and good performance in workpiece precision. However, various tool factories at home and abroad have different names for the special tools combined with the above multiple functions. Some people call them compound tools, others call them special tools, or classify these types of tools into forming tool types. There are many market sayings, and this article will It is collectively referred to as “composite toolâ€.
Cutting technology: The term "composite tool" covers three broad categories of "composite tools". The term "composite tool" covers a wide range. This article roughly divides composite tools into three types: one is a combination of multiple functions, such as: bit hinge Hole compound tools, drill chamfering compound tools and drill wire tapping composite tools, etc., are the most common types of composite tools in the market that are currently the most visible and demanding. The main design mode is the combination of the drill bit and other functions; the second is a single tool but can be processed separately. For example, the composite turning tool can not only cut the outer diameter on the X-axis, but also cut the outer diameter. The inner diameter cutting, the inner diameter grooving, and the use as a cutting knife to cut the residual material, etc., give a plurality of processing capabilities in one tool, and the Asahi knife series produced by Iskar is a composite tool of this type. The last composite tool is a knife that can cut on different materials. More and more products are made up of a variety of materials. In the past, hard materials such as steel were used to cut a tool. Soft metals, such as aluminum, use a second knife, but as the workpiece is progressively multi-material composite, the tool will also produce special tools that are specifically designed for composite workpieces.
Cutting technology: time is money efficiency is the competitiveness of traditional tool manufacturers to include composite tools in special tool products, not mass production, but tailored to individual cases, but in the past two years, composite tools have begun Is there a standardized stocking procedure at some tool manufacturers? Does this mean that the market demand for composite tools will gradually increase? Taiwan’s Isa project manager Lin Jinsheng affirmed that “using time for money†will be a competitive advantage for future manufacturers, so the processing efficiency of each factory will be faster and faster in the future, and the better the efficiency represents the market competitiveness. The better, the composite tool can reduce the processing time and increase the accuracy of the workpiece for the user, and the demand in the market will become larger and larger.
However, the problem of stocking of compound tools in the standardization process has caused many tool manufacturers to worry. Most of the composite tool designs are often developed for specific workpiece machining requirements. Different workpieces have different composite tool counterparts. It is difficult for the tool factory to standardize the production of all composite tools, but if the productivity of a single workpiece is extremely large, it should The composite tool for workpiece production can be mass-produced, but if the workpiece is not mass-produced, the number of composite tools is relatively limited. Therefore, the tool manufacturer standardizes the compound tool under the processing demand of small production volume. At the time of the procedure, the risk of stocking that must be borne is extremely high.
Cutting technology: multi-technology integration is not easy. The cost of composite tools is high. Combining multiple tool technologies is another problem for tool manufacturers to carry out compound tool standardization procedures. Liu Zhimin, manager of YAMAWA sales department, said that the combination of composite tools The project has different cutting principles. For the tap and the drilling function, the tap is made by extrusion during the feeding, and the drilling must use a certain cutting rate to have superior cutting force and row. Chip rate, when the two are combined, there must be one machining that must be bent to another machining. For example, the drill can maintain a certain speed at the beginning, but it is drilled to the end and the tapping starts to tap the screw. When the drilling process in the front section needs to reduce the rotation speed and bend the screwing process at the back end, the tool manufacturer must have two kinds of tool specialty Know-How to obtain the best between the two when producing the multi-purpose composite tool. Balance the point and design.
The cost problem caused by the small amount and high technology is the biggest difficulty in standardizing composite tools. At present, Taiwan's tool market has about NT$2.8 billion a year, and some of its tools are exported to mainland China. The actual tool market in Taiwan is about 2 billion yuan, which is more than the start of the machine market. The tool market is small, but there are many people who eat it, both at home and abroad.
In the fierce competition, cost becomes the key to market procurement. Compared with the low cost of standard tools, the price of composite tools is much higher. Customers may not choose high-priced composite tools, not to mention the continuous improvement of machine capacity. The precision and time advantage of composite tools are gradually reduced, and whether it will become the mainstream of the market will become weaker in the future.
Cutting technology: Who is the composite knife for the standard knife deer?
Of course, the tool factory will not be knocked down due to cost problems. In order to reduce the cost of each factory, the price is reduced by materials and tool design, for example, reducing the proportion of high-cost tungsten steel used in tool bars and designing modules. In order to solve the problem that the size is difficult to unify, or in response to the development of the new machine, and with the multi-steering integrated machine spindle, we will develop more innovative composite tool products, so that the composite tool will rekindle the market war.
As for the resounding of the innovative composite tool in the market? Lin Fangxian, chairman of the company, said: "Compared with the high demand, the composite tool is better than the general tool product." The largest part of the global market demand for tools is still on the standard tool. The composite tool is just a tool. A small corner of the market, the choice to develop a composite tool with high risk of stocking is not as focused on the technical improvement of general tools. Liu Zhimin also said that the current tool development market is not as good as the development of high-speed tools in response to high-speed machinery. After all, the development of composite tool market is not easy, and there is no obvious improvement in the current market sales. Where will the tool expand? Can composite tools occupy a place in the market? I believe that time and market will give a final reply.
