CNC Knowledge: Flat rotating disc used in machining center is also called U axis tool

The flat rotating disc is also called the U-axis tool. The U-axis generally refers to the axis parallel to the X-axis of the machine tool. The U-axis tool can be digitally controlled in real time in the U-axis direction, so that it can also be realized on machine tools such as machining centers. In the past, this could only be achieved by tricks.

CNC flat rotating discs and variable diameter CNC boring heads (also called U-axis tools) are used in horizontal boring and milling machines, floor boring machines, machining centers with telescopic shaft functions and various special machine tools to complete the machining of boxes. and structural parts. And other complex bore processing parts. Widely used in the following industries:

1. Aerospace;

2. Manufacturing of valves, control of hydraulic fluids;

3. Equipment for shipbuilding and heavy industry;

4. The main equipment manufacturing fields such as energy, petrochemical industry; Different from ordinary boring tools, CNC flat rotating discs and variable diameter boring heads (also called U-axis tools) can change the cutting diameter in CNC in real time during the processing process. ;

Features and advantages of CNC flat rotating disc and variable diameter CNC boring head (U axis tool):

1. Fully digitally controlled. While the spindle rotates, the tool can be digitally controlled in the radial direction and can change diameter in real time during processing. Therefore, curved surfaces and spherical surfaces can be processed with good precision, and complex hub holes can be processed. be treated, as small at both ends and large in the middle of the bottle-shaped cavity;

2. A CNC flat rotating disc and a variable diameter CNC boring head are equivalent to the processing capabilities of countless boring tools; whether the user designs a new product or carries out product improvement design, it can be adjusted by rewriting the machine program; tool to adapt to new processing requirements without the need to purchase other tools, saving tool costs;

3. The system has multiple fixed connection methods to ensure that it can be easily connected to machine tools and exchanged between machine tools;

4. Using CNC and only one tool setting is required, it greatly reduces the time of tool changing and auxiliary operations, and improves the machining accuracy and processing efficiency. production.

The requirements for machine tools for the application of CNC flat rotating discs and variable diameter CNC boring heads (U-axis tools):

The machine tool must have a programmable control axis, usually the W axis;

Generally suitable for boring and milling machines, machining centers and special machines with telescopic W axis!

The working principle of CNC flat rotating disc and CNC variable diameter boring head:

Through the CNC program, the expansion and contraction of the boring bar is converted into the horizontal movement of the tool through the precision mechanism of the flat rotating disk; the axial movement of the tool is achieved by the movement of the cylinder or the movement of the workbench.

Types of parts that can be processed by CNC flat rotating disc and CNC variable diameter boring head:

1. Drill holes of different diameters on conical surfaces, cylindrical surfaces and multi-diameter profiles;

2. Used for automatic processing of complex geometric contour boring, such as tapered holes, complex contour variable diameter holes, such as cavities whose inner contour diameter is larger than the diameter of the orifice (bottle cavity bore);

3. Reverse boring and reverse end boring, chamfering, radial grooves and end grooves, threads, etc.
