What is called five-axis linkage

Five-axis linkage is a CNC term, linkage is a CNC machine tool axis at a certain speed at the same time to reach a set point, five-axis linkage is five axes can be. Five-axis linkage CNC machine tool is a high-tech, high precision machine tools dedicated to processing complex surfaces, this machine tool system for a country's aviation, aerospace, military, scientific research, precision instruments, high-precision medical equipment and other industries, has a significant impact. Equipment manufacturing industry is the cornerstone of a country's industry, it for the development of new technologies, new products and modern industrial production to provide an important means, is an indispensable strategic industries. Even the developed industrialized countries, all attach great importance to.

Five-axis machining refers to a machine tool with at least five axes (three linear coordinates and two rotary coordinates), and can be coordinated under the control of the computer numerical control (CNC) system for processing.

Five-axis machine tools have vertical, horizontal and cradle type two-axis NC table, NC table NC indexing head, NC table 90-axis, NC table 45B-axis, NC table A-axis, two-axis NC spindle and other types. The above six categories **** 7 kinds of five-axis linkage have their own characteristics, can not say which form is better, can only say that your product is suitable for which type of five-axis machining.

(1) five-coordinate linkage double rotary table machine tools

(A) rotary coordinates have sufficient travel range, good process performance.

(B)Due to structural constraints, the rigidity of the swing coordinate is low, which becomes the weak link of the rigidity of the whole machine tool. The double rotary table machine tool, the rigidity of the rotary table is much higher than the rigidity of the pendulum head, thus improving the overall rigidity of the machine tool.

(C) easy to develop into a machining center. Only need to add an independent tool magazine and tool changer robot can be but double rotary table machine tool rotary table coordinate drive power is larger, coordinate conversion relationship is more complex.

(2) five-coordinate linkage double pendulum head machine tools

Double pendulum head machine tools swing coordinate drive power is smaller, easy loading and unloading of workpieces and coordinate conversion relationship is simple.

(3) five-coordinate linkage of a pendulum head of a rotary table machine tools

a pendulum head of a rotary table machine tool performance is between the two.

Features

1, can effectively avoid tool interference.

2, for straight surface parts, can be used side milling method of one cut molding.

3, for the general three-dimensional surface, especially the relatively flat large surface, can be used to large diameter end milling cutter end face close to the surface for processing.

4, can be loaded at a time on the workpiece of multiple space surface for multi-face, multi-processing.

5, five-axis machining, the tool relative to the surface of the workpiece can be in the most effective cutting state. The error distribution on the surface of the part is uniform.

6, in some machining occasions, can use a larger size tool to avoid interference for processing.
