How to ensure the accuracy of gantry milling machine

Nowadays, the use of gantry milling machine is very common, especially in recent years, several high-precision machine tools have been developed.

No matter what kind of precision milling machine, it is necessary to do a good job in daily maintenance, otherwise it is easy to have some small faults, which will affect the accuracy of gantry milling machine, let's let Xiaobian tell us what's going on.

The gantry milling machine comprises a bed, a worktable mounted on the bed and a numerical control circuit control system. A gantry is erected on the movable span above the worktable, and the gantry also includes a gantry carriage, which is clamped on the x-axis guide rail. The z-axis guide rail is installed on the gantry. The crossbeam is provided with a Z-axis carriage, the crossbeam is movably clamped on the z-axis guide rail through the z-axis carriage, and the crossbeam is also provided with a Y-axis guide rail.

When we use gantry milling machine for operation, we must strictly follow the corresponding procedures to operate, but also check the voltage and power grid. If we boot five minutes later show that everything is OK, then we can start normal operation. It is necessary to turn on the automatic lubrication system, to see if the guide rail has done a good job of protection, and to wipe oil. When the machine is shut down, it is also necessary to remove the dirt produced by the machine, and to wipe oil on the guide rail and the workbench,

Then turn off the power, only pay attention to the details can have the high accuracy of gantry milling machine.

Generally speaking, the high efficiency of this machine tool depends on its cutting capacity. Of course, the force of the gantry milling machine depends on the engine, and its screw rod should not be forgotten. If the screw rod does not meet the requirements or is too thin,

The power will increase, and the speed will be very fast. At this time, the amount of cutting will be relatively large, but the screw rod may break, so we have to consider the bearing capacity of the screw rod.
