The three -axis vertical CNC machining center can treat various machining in the horizontal plane, and the horizontal machining center with three CNC axes can treat various machining in the vertical plane, but for certain parts which must be treated at the same time On several surfaces, they are treated in CNC machining with three axes. Now, but here, this implies with regard to the problem of the secondary correction of the parts, this article briefly presents the common methods and techniques for the secondary tightening of the parts, and hope that it will be useful to everyone.
Part processing site CNC Machining Center
1. Second part of the parts
The aforementioned parts are processed on the CNC machining center with three axes. Secondary tightening and correction. There are many methods and instruments for the secondary alignment of machining parts, some are more advanced and some are more traditional. Clear.
Of course, in the real treatment of parts, we must also reasonably choose the correct operating method according to specific processing accuracy, process requirements and specific processing conditions. Join the learning group QQ 304214709 and everyone will go together.
2. Current methods for the secondary correction of the parts
Ordinary tool instruments cannot directly contact the fine reference surface, and the operation is relatively heavy, which is often wasting time but cannot guarantee accuracy. It is much more difficult to find the secondary tightening and rectification of the part than that of tightening and rectification, because at this time the surface of the knife is the fine reference plane rather than the thick reference plane. The two commonly used secondary correction methods include the PAD block method and the lever numbering method.
The CNC machining center corrected by the lever dial table
1. Lever figure method
The lever dial meter method consists in sucking the lever dial meter on the main axis of the CNC machining center, so that the dial counter is in a narrow horizontal position, then lower the dial counter to the precise reference surface to be corrected, and pass the pulse hand from the CNC CNC system. At the same time, erase the relative coordinates values of the CNC system linked to the CNC machining center. Move the dial on the other side of the part by the hand and lower the dial to the precise reference plane.
Mass blocks commonly used in CNC machining centers
2. Pad block method
The PADBS block method requires the use of auxiliary tools such as standard platelet blocks to translate the fine reference surface of the room. Put a standard cushion between the tool gauge and the part, install a photoelectric shot researcher on the spindle of the CNC machining center, rotate the spindle at low speed, and the photoelectric edge researcher directly affects the side pads left and right. The value is the error value.
