The importance of cutting tools and numerical control equipment in mechanical processing needs to be fully understood

　 Tool weight
In the process of machining, metal cutting machine tools and cutting tools as the basic processing equipment, cutting tools are known as the "teeth" and "twins"
Born brothers, no matter what kind of metal cutting machine tools, must rely on this "teeth" to play a role, leaving the "twin brother
Brother is nothing. The performance and quality of the tool directly affect the production efficiency and the quality of the machine tools
The production technology level and economic benefit of the whole machinery manufacturing industry. Therefore, said: "the enterprise bonus in the blade", which is a foreign enterprise
Keenly aware of the. The ancients said: "to do good work, must first sharpen his" modern people, said: "quicken work", "to make fresh in
These are all the experiences of the working people in the long-term production practice.
Tool weight two
Actual production shows that the tool is small, the potential is infinite". Such as rough machining of a 200 thousand KW generator rotor shaft, net weight of 30 tons, forging blank of 60
-70 tons, waste chips accounted for more than 50% of gross weight, if there is no efficient tool is not good. Another example of finishing a heavy-duty precision gear,
There is no one of 800 thousand yuan of high-performance high-precision hob is not good. An international cutting and machine tool
It is argued that "improving the cutting tool has the potential to reduce the cost of cutting more than any other single process. Reasonable choice and
Application of modern cutting tools is the key to reduce the production cost and obtain the main economic benefits." N., another American expert, said: "one
The value of 250 thousand yuan of NC machine tools, its efficiency is largely dependent on the performance of a $30 milling cutter". So often
Listen to western entrepreneurs, said: under the knife".
Tool weight three
Improve the level of modern science and technology, equipment replacement speed is accelerating, 10 to 15 years for a generation, in such a short period of time to make investment in equipment and
To create profits, it is necessary to invest in research to improve the potential to rely on cutting tools. According to the information shows that: the cost of cutting tool manufacturing costs 2.4-4%, but it
Directly affect the cost of manufacturing accounted for 20% of the machine tool costs and labor costs of 38%. There is also an algorithm: the machine tool and the input ratio of 9: 1 to 7
: 3. As long as the tool investment in place, cutting speed and feed rate per 15-20% can reduce the manufacturing cost of 10-15%. So buy the machine at the same time
Must consider the configuration of the tool, in order to efficient operation. Also, to achieve three durability (ie, maximum productivity, minimum cost and maximum profit
Run rate) to know will grasp the real money spent on the blade, in order to quench production. The problem is that people can not keep up with the idea that the machine is solid
Fixed assets, knives are consumables. Resulting in donkey immortal, not grinding, willing to spend money to buy advanced equipment inefficient operation, reluctant to spend money to buy
The strange phenomenon of high efficient tapping of advanced tools. This is hampering the development of productive forces "stumbling block" and "stumbling block".
The equipment of war
The reason for the low utilization rate of NC machine tools in our country is that the operating rate of foreign CNC machine tools in two shifts is 60-70%
Can only reach 20-30%, the reason:
Users blindly purchase CNC machine tools, resulting in the goods are not right";
CNC machine tools related to the low quality of technical personnel;
Low programming efficiency;
Long maintenance time, maintenance work can not keep up;
The working environment of CNC machine tools (voltage fluctuation, environmental temperature, humidity and strong electromagnetic interference, etc.);
The NC machine tool is the low level of management, backward technology preparatory work;
The special emphasize is machine tool and cutting tool technology, advanced machine tool, "and backward",
Do not know how to "match", "a good horse with a good saddle", "unreasonable use of equipment, put fine timber to petty use" the potential has not fully played out, and
An important reason for the huge waste.
The key of the tool and the numerical control processing equipment in the actual production is irreplaceable
The use of efficient processing equipment and tools, in order to truly achieve industrial power, there is still a long way to go.
