SV-20R CNC Swiss-type Automatic Lathe Specifications and Accessories Overview

The SV-20R offers exceptional flexibility and efficiency in machining operations. It can handle a maximum machining diameter of 20mm (optional upgrade to 23mm) and has a 205mm headstock stroke. With its gang-type and turret-type tool post configurations, the machine supports up to 6 tools in the gang post and 8 stations in the turret, accommodating complex turning, milling, and drilling operations. The backworking 8-spindle unit with Y-axis control allows for simultaneous machining of multiple parts, improving productivity and precision.

Equipped with C-axis control on both the main and sub spindles, the SV-20R ensures accurate tool positioning and efficient secondary operations. The Star Motion Control system minimizes non-cutting time, further boosting efficiency. Additionally, the machine鈥檚 ability to switch between guide bush and non-guide bush modes makes it versatile for different machining needs, allowing for both long and short part production.
