Efficient cutting tools can not only directly reduce the tool cost of the powertrain, but also indirectly bring about a significant reduction in production costs, in line with the "lean manufacturing" principle - with the minimum investment to win the most economic benefits. The dominant role of high-efficiency tools in powertrain lowering costs is mainly reflected in the reduction of equipment investment, the reduction of the cost of one-piece tool parts, and the reduction of production costs.
The price of efficient tools is often relatively expensive, but sometimes inexpensive tools can achieve good results, so only the right ones are the best. However, the performance of high-efficiency tools is generally higher than that of traditional tools, and the cost of single-piece tools for general parts is generally reduced. For example, the same size of the hard alloy reamer and PCD reamer in the engine aluminum alloy parts, the price of PCD reamer is generally 3 to 5 times the hard alloy reamer, tool life on the PCD reamer is generally It is 10 times that of cemented carbide reamers, and the cost of a single-piece tool can generally be reduced by 50% or more. For the existing production line, the continuous development of tool technology enables the tool cost to continue to decline under the premise of full play of tool performance. The new material and new coating of high-efficiency cutting tools have a 10% to 30% increase in tool life compared to the original tool, and the prices are generally the same.
The efficiency of high-efficiency cutting tools for the production line ultimately manifests itself in the reduction of production costs, such as reducing the unit processing time of parts, reducing the time of tool change, increasing the starting rate of the machine tool, reducing the tool management cost, and reducing the tool inventory cost. However, high-efficiency tools do not have good processing results if they cannot be used properly. According to reports, some companies have purchased a large number of imported high-performance machine tools, but they have chosen conventional low-performance tools. The performance of the machine tools has only reached 10% to 20%. Because of the short tool life, the machine tool frequently stops the tool change. On the surface, the cost of the tool may be relatively low, but if the depreciation cost of the equipment is spread over fewer parts, the cost of the part is bound to rise significantly in terms of the production cost of the part. So a sensible choice should be to use efficient tools to maximize machine tool output per unit of time, thereby minimizing production costs.
Fully and reasonably exert the performance of efficient tools
The requirement for improving efficiency in the powertrain production of the automotive industry is to use as few machine tools as possible to produce more parts in a unit of time. The specific application of high-efficiency tooling is to increase the metal removal rate per unit time and reduce the number of machine tools. Auxiliary time without cutting improves the starting rate of the machine tool. Increasing the metal removal rate per unit time of the machine tool is mainly achieved through the high cutting speed and high feed rate of the high-efficiency tool; the use of high-efficiency, high-quality, and high-stability combined tools is used to reduce the non-cutting assistance of the machine tool. Time, to improve the production efficiency of the powertrain production line, not only reduces the processing time, but also reduces the auxiliary time such as tool change, improve the production cycle, improve the production efficiency; by optimizing the application, improve tool life, reduce The frequency of tool change in production increases the starting rate of the machine tool, thereby increasing the production efficiency of the production line.
