Tool clamping process and common forms of five-axis machining centers

1. The tool of the five-axis machining center should be clamped reliably, and the handle should not be too short.

2. The five-axis machining center should check whether the tool can meet the requirements before each lock of the knife, and the length of the cable cutting machine should be determined according to the processing depth guided by the sequence table, generally the machining depth value of 2mm is slightly better, consider whether the handle can collide.

3. In the case of deep processing, you can communicate with the programmer, you can take the method of two pairs of tools, that is, first cut half to two-thirds of the length, and then cut a little longer when processing to a deeper position, which can improve the processing efficiency.

4. When using extended cable heads, it is especially necessary to understand the data of cutting depth and required cutting length.

5. Before the cutterhead device is installed on the computer, the taper matching position should be wiped clean with a clean cloth, and the corresponding position of the tool sleeve of the machine tool should be equally clean, so as not to affect the accuracy of the iron filings on the mating surface and damage the machine tool.

6. The five-axis machining center usually adopts the tool tip to tool method to match the length of the tool (in the case of the tool under special circumstances), and carefully check the instructions of the sequence table when the tool is set.

7. In the five-axis machining process, when the program is suspended or the tool needs to be re-aligned, pay attention to whether the depth can be connected with the back, under normal circumstances, the back line can be raised by 0.1mm, and then adjusted according to the situation.

8. For the rotating cutterhead, if water-soluble cutting fluid is used, it is necessary to soak in varnish for several hours every half month for maintenance, so that the external parts of the cutterhead are smooth and not worn.

What are the forms of five-axis machining centers?

Five-axis machining is a way of CNC machine tool processing, the machining center we usually use now is generally a three-axis three-linkage machining center, three-axis refers to the X-axis, Y-axis and Z-axis of the machining center, of course, there are also four-axis machining centers, four-axis machining center refers to the X-axis, Y-axis, Z-axis and A-axis, where the A axis refers to the axis rotating around the X-axis, five-axis machining center refers to the B-axis other than the X-axis, Y-axis, Z-axis, B-axis refers to a rotating axis around the Y axis, the technology has been widely used in ships, aerospace, automobiles, light industry , medical and other equipment manufacturing.

To understand the five-axis machining center, the first thing to understand is what is a five-axis machine tool, five-axis machine tool as the name suggests refers to the commonly used X, Y, z three linear axes to increase two rotary axes, A axis, B axis, C axis in the two rotary axes have different motion methods to meet the technical requirements of various products, in the mechanical design of five-axis machining centers, machine tool manufacturers have been unremitting efforts to develop new motion modes to meet various requirements, currently comprehensive market of various five-axis machine tools, mechanical structure variety, However, there are mainly the following forms:

1. Two rotation coordinates directly control the direction of the knife axis (double pendulum form).

2. The two axes are on top of the tool, but the axis of rotation is not perpendicular to the linear axis (pendulum).

3. Two rotation coordinates directly control the rotation of space (double turntable form).

4. The two coordinate axes are on the table, but the axis of rotation is not perpendicular to the linear axis (tilting table).

5. Two rotation coordinates one on the tool and one on the workpiece (one swing and one turn).
