STEP Operation Control pays close attention to various technical difficulties in the laser cutting industry, and introduces a variety of different solutions to the market. With its high precision, high efficiency, high performance and high cost performance, it has won the favor of many customers!

Plate Laser Cutting Machine

01Equipment introduction

The laser cutting machine tool is mainly composed of 4 axes in the above figure, among which the X axis controls the left and right movement, the Y1 and Y2 axes control the front and rear movement (synchronization), and the Z axis (height adjustment axis) controls the up and down movement. Place the plate to be cut on the workbench, and ensure high-precision cutting effect through the quick response of these 4 axes.

02 Application scheme

The main configuration is shown in the figure below. The laser cutting machine tool system controls 5 axes through pulses. The X-axis, Y1 and Y2 axes on the equipment are driven by rack and pinion and screw. The interference of the resonance point in the system will greatly affect the machining accuracy and surface smoothness. The online inertia self-identification function driven by Ωs-AP1 can accurately Calculating the real inertia can effectively save debugging time and suppress resonance points, providing the most favorable guarantee for the machining accuracy of the system.

Tube plate integrated laser cutting machine

01Equipment introduction

When the tube-sheet integrated fiber laser cutting machine is used as a tube cutting machine, the R-axis and C-axis constitute the support of the tube, and the Y-axis adjusts the distance between the R-axis and the C-axis to adapt to different tube materials. Then, cooperate with the XY and Z direction movement of the laser head to realize the cutting of the pipe. When the tube-plate integrated fiber laser cutting machine is used as a plate cutting machine, the plate is placed on the support surface of the machine tool, and the laser head moves in the XYZ direction for laser cutting. At this time, it has nothing to do with the R-axis, C-axis and Y-axis.

02 Application scheme

This motion scheme contains a total of 7 axes, of which 4 axes for laser mobile cutting: X axis, Y1 axis, Y2 axis and Z axis; three axes for pipe cutting: R axis, C axis and Y axis, R, C The axis rotates the pipe, and the Y axis moves through a rack and pinion mechanism to match pipes of different lengths.

These two solutions use the Ωs-AP series servo drive, which is a pulse-type single-axis product launched by Sigriner. The drive integrates drive, control, pulse control, I/O and other functions, and can support a variety of encoders, such as Panasonic, Tamagawa, Heidenhain, Nikon, etc. It is a veritable high-performance product for any user .

Summarize

For the laser cutting machine tool industry, the most troubling thing in metal processing is that it is difficult to confirm the specific values ​​of the inertia of the three axes of the gantry structure. If the inertia of the three axes cannot be accurately known, it will affect the synchronization of the gantry structure and will Causes tangent circle defects.

The high precision of the tube-plate integrated laser cutting machine is mainly guaranteed by the XY plane movement composed of the Y1, Y2 axes and X-axis of the gantry structure, and the motion response of the gantry structure is very important.

The online inertia self-identification function of the Ωs-AP servo driver can not only effectively identify the specific value of the inertia, but also is easy to debug, and can quickly realize the precise synchronization and positioning stability of the gantry structure.
