Domestic and international initiative
1, overview:
The machine tool is a new generation numerical control electrode double thread comb machine tool which is independently developed by our company. The control unit for the company to develop a dedicated six axis high performance CNC system and software, the use of Japanese production AC servo motor drive, the key components are world famous products.
2, technical description:
The machine tool is the all numerical control machine tool, completely eliminates the mechanical transmission chain error, through the numerical control method directly forms the thread pitch, the taper and the diameter, the processing precision is obviously ahead of Japan, the US, the German similar processing equipment level.
The machine tool structure is unique, the workpiece is not moving, the spindle is rotating slowly with the X axis and the Z axis linkage.
Comb knife with a special method of driving, high-speed rotation of up to 1500RPM.
- end use of CNC to ensure the verticality and scraping, and concave thread axis.
- Z to achieve floating positioning, positioning accuracy.
- machine tool can be used for a long time and will not reduce the processing accuracy.
3, the main technical performance indicators:
- electrode diameter: diameter of 200 ~ 800mm in diameter
- processing electrode length: 1500 ~ 3200mm
- Spindle AC servo motor power: 11Kw
- Z feed servo motor power: 4.4Kw
Thread single tooth pitch error: + 0.015mm
- thread pitch cumulative error: = 0.06mm / 150mm
- threaded hole effective diameter: 0 ~ 0.05mm
Electrode thread axis and the end verticality: less than 0.015mm/ with 250mm
Thread taper error: 9 27'44.5"
Z to pulse equivalent: 0.001mm / pulse
X to pulse equivalent: 0.0005mm / pulse
- unit processing time: less than 3min (including face scraping)
- machine tool weight (ton):24
