Perform highly complex front/back simultaneous machining with dedicated back tool post and X2, Z2 axis on the back spindle. In combination with the rapid feed rate, SG-20 has substantially cut cycle times. No wonder SG-20 is acclaimed by customers as a highly rigid, reliable and versatile machine.
9 tools for OD
4 tools for face ID
8 tools for back ID
SG-20 makes it possible to complete a wide variety of tooling jobs at one time.
Standard machine tool post layout.
Built-in motor spindle on front and back spindles
They have high power up to high speed and maintain high precision and low vibration all in one simple mechanical structure.
Built-in main and back spindle motors increase tooling accuracy.
Servo rotary guide bushing enables high-speed and accurate machining.
With the increase in material cost in recent years, it’s great that SG-20 has chucker mode to reduce waste. In chucker mode, the machine doesn’t require the space between the guide bushing and the collet so there is less bar remnant. Chucker mode does not require the use of ground bar stocks, so it is suitable for cold-drawn bar machining. In addition, the powerful chucking force enables heavy cutting, minimizes roughness and improves roundness. The user can choose between guide bushing mode or chucker mode according to the length of the part to be produced and be able to convert to chucker mode in minutes.
Unlike conventional machines, direct C-axis indexing enables deceleration to the chosen index position directly, without the need to home return, reducing spindle indexing time.
