AI Technical Summary
Existing technologies cannot meet the requirements of high-precision and high-stability precision grinding for extra-large support rollers. Traditional methods suffer from problems such as low machining quality of the conical surface of the center hole, high cutting resistance, limited machine tool spindle speed, and clamping methods that cannot withstand the weight.
The high-precision machining technology of center hole is achieved by combining gantry milling CNC rotary table with grinding fixture. High-precision center hole is formed by rough boring and fine boring. Combined with the clamping scheme of auxiliary support of bearing seat and high-precision center support, high-precision grinding under extreme weight is achieved.
It improves the contact rate between the center hole and the tip, improves the stress state during the grinding process, reduces the risk of grinding damage, and achieves high-precision and high-efficiency grinding, meeting the design requirements of extra-large support rollers.
