Description
When machining motor housings on a CNC vertical lathe (vertical lathe), the machine primarily leverages its vertical spindle configuration and robust load-bearing/clamping capabilities to meet the demands of machining these typical disc- and housing-type parts, which require large diameters, high concentricity, and complex shoulder machining.
Motor housings (especially large ones, such as those for nuclear reactor coolant pump motors) typically exhibit the following characteristics:
Complex structure: They include coaxial stepped bore systems, end-face bore systems, flanges, and other features, requiring extremely high dimensional, geometric, and positional accuracy.
High material requirements: They are often made of high-strength alloy steel or wear-resistant cast iron, necessitating high-rigidity equipment to suppress cutting vibrations.
Challenging deep-hole machining: For example, the main bore of a motor housing may exceed 1,000 mm in diameter and reach depths of 2,500 mm, requiring solutions to address insufficient rigidity caused by excessive ram overhang.
Multiple machining operations: Multiple operations are required to complete external cylindrical surfaces, internal cylindrical surfaces, and end-face hole systems, with strict control over reference consistency between operations.
