From the perspective of revitalizing the national industry, the development of domestic machine tool factories should be supported. The essence of high-speed cutting is to complete the walking length of the tool in a short time. Everybody knows
distance = speed × time
The description of the tool has been fixed by the country's cutting method. If it is longer, it means that the unprofitable increase in speed is equivalent to shortening the time.
High-speed cutting is not necessarily good due to the limitations of the current machine tool’s own spindle and the used tools. The current general practice in foreign countries is that the first machine does not use high-speed cutting, and the second or third machine can be considered This equipment.
Examples of successful practices:
One copy milling machine can complete most of the cutting volume (heavy cutting), leaving a machining allowance of 2~3mm. The remaining cutting volume can be completed quickly on a high-speed machine tool. This has many advantages:
1)--There are many heavy-cutting machine tools, and the processing cost is very low
2)---large processing volume, low precision requirements, easy to achieve
4)--After switching to high-speed cutting, the cutting amount of the first cut is very uniform because the object to be processed is close to forming
5)-fast and accurate forming
6)-avoid too much polishing, accurate matching size
7)--Although the tool is expensive, the time is short, the cutting volume is not large, and the performance-to-price ratio is very good
8)-Many subtle points, such as small angle conduction, etc., can be processed in one step without the help of electric sparks.
9)-excellent surface finish (mirror effect)
