AI Technical Summary

Technical Problem

Existing ordinary vertical lathes are difficult to efficiently process the tapered annular annealing furnace bottom plate, especially the tapered surface with high surface roughness requirements, resulting in high processing costs and difficulty in meeting design requirements.

Method used

By structurally transforming the ordinary vertical lathe and installing gears and transmission gear systems, the polished rod and the lead screw are linked to achieve proportional rise of the tool holder when it moves horizontally. Combined with the servo motor and lifting drive mechanism, the function of CNC vertical lathe is realized, which can process furnace bottom plates with inclined surfaces.

Benefits of technology

It reduces processing costs, improves processing efficiency, can meet the surface roughness requirements of the bottom plate of the annular annealing furnace, reduces the cost of outsourcing the company's product processes, and increases economic benefits.
