Used Lathes

Brief introduction

The CA6140A horizontal lathe is a classic universal lathe optimized and improved on the basis of China’s CA6140. With its reliable structure and stable performance, it has long been a mainstay equipment in small and medium-sized mechanical processing workshops.

Performance Characteristics and Application Scenarios

•Strong Versatility: It can perform various processes such as turning internal and external cylindrical surfaces, conical surfaces, end faces, steps, grooves, and cutting-off, as well as turning various metric, inch, module, and diametral pitch threads. It is suitable for processing small and medium-sized shaft and disc parts.

•Easy Operation: Adopting mechanical transmission and manual operation, it has an intuitive structure and is convenient to maintain. The skill requirements for operators are relatively moderate, making it suitable for mass production or single-piece small-batch processing.

•Stable Precision: The guide rails are precision ground, and the spindle runout is small. The machining accuracy can reach IT8-IT7 grade, with a surface roughness of Ra1.6-3.2μm, meeting the precision requirements of general mechanical parts.
