Swiss type CNC automatic lathe

SR-20JIISwiss type CNC automatic latheTo meet diverse processing needs, SR-20J Ⅱ has undergone further evolution. The Y-axis guide rail of the tool holder platform adopts a tilted dovetail groove guide rail structure. Therefore, the X and Y axis guide rails form a radial shape near the cutting point, which can improve mechanical rigidity. In addition, the Y-axis guide rail through which the center of the ball screw passes is a parallel straight line that is in close proximity to the cutting point (a1), which can reduce the torque load caused by cutting resistance Improve the rigidity of the tool holder in the Y-axis and Z-axis directions.

SR-20JIISwiss type CNC automatic latheCharacteristics:

1. High rigidity and high precision

As a front processing tool, it is equipped with a high rigidity "inclined dovetail groove guide rail structure" row type tool holder. Y1 axis and X1 axis both use dovetail groove guide rails.

In the N.G.B specification, the "spindle cylinder sliding guide surface structure" is adopted. Supporting cutting force on the sliding guide surface to achieve high rigidity of the spindle table.

The Y2 axis sliding part of type B adopts dovetail groove guide rails. Improved the rigidity of the back knife holder platform.

● Use a built-in spindle on the main/auxiliary spindle. Improved spindle indexing accuracy.

2. High functionality and processing capability

Equipped with G.B./N.G.B. switching mechanism.

● Achieved high output of secondary spindle and power tool motor. (Compared to SR-20J)

(Auxiliary spindle) 1.5/2.2kW → 2.2/3.7kW

(Power cutting tool) for horizontal machining: 1.2kW → 2.2kW, for back: 0.5kW → 1.0kW

There are two types of horizontal drilling units equipped on the 5-axis type.

(1) 3 horizontal dedicated (ER16)+interchangeable 2pos

(2) 3 horizontal dedicated (ER20 × 1, ER16 × 2)+interchangeable 2pos

Both Type A and Type B are equipped with 4-axis and 8-axis back tool holder platforms with Y-axis control. TypeA/B can install power tool units on all tool positions.

The back tool holder platform expands the spacing between the tools to allow for a 20mm outer diameter rotary cutting without being restricted by adjacent tools.

Materials with a maximum size of $23mm are available for selection.

3. Operability and Homework

The cutting chamber and spindle table chamber both use large opening upward swing doors. Ensure a spacious workspace.

Through the movable control panel, the optimal position can be operated.

Simplify the replacement of various optional components such as tubular product discharge devices.
