Summarize the machining accuracy and reduce failure rate of a five axis machining center

The high-speed five axis machining center mainly includes a base, on which an X-axis track is laid, and a gantry column is displaced along the X-axis. The gantry column is equipped with a horizontal track, and a Y-axis machining head movement device is installed on the track, allowing the machining head to adjust its position or displacement for machining feed in the Y-axis.
​
The machining head is equipped with a Z-axis slide rail to assemble the Z-axis machining head lifting device, allowing the machining head to adjust the position or displacement of the Z-axis for machining feed. The existing machining machine bases are mostly single arm structures, with gantry columns installed on the bases that bear excessive pressure and are driven by a single motor. The machining process is unstable, takes up large space, is not easy to adjust, and has poor portability.

The structural characteristics of a high-speed five axis machining center:

The main structure of the machine tool adopts a crossbeam movable gantry structure, with a fixed workbench and high load-bearing capacity, and the machining characteristics of the machine tool are not affected by the quality of the workpiece.

X-axis gear and rack drive, with large load-bearing capacity and gantry synchronous dual drive control technology, ensures smooth movement and high accuracy.

The linear axis adopts a large-sized and high-precision roller linear guide rail, and the installation surface of the guide rail adopts manual scraping technology, which can achieve stable and high-precision work.

The rotating axis A/C adopts torque motor direct drive, with high accuracy and fast response.

An important advantage of a high-speed five axis machining center is that it can use shorter cutting tools because the head can be lowered towards the work and the tool can be facing the surface. Therefore, higher cutting speeds can be achieved without applying too much load to the tool, thereby extending tool life and reducing damage.

The use of shorter tools can also reduce tool vibrations that may occur when using a three-axis machine tool to process deep cores or cavities. This can achieve higher quality surface finish, thereby reducing or even eliminating the need for time-consuming manual finishing.
