With the continuous development and innovation of high technology, there are more and more CNC milling machine processing methods. What are the specific processing methods? People may not know how to process it. If there is anything else you don’t know, you can pay attention to the following information!
1. Flat hole system parts
It is commonly used to process point and line controlled computer gongs (such as CNC milling machine and drilling machine). When selecting the process route, two principles of processing accuracy and efficiency are mainly considered.
2. Rotating parts
Commonly used CNC lathe or grinder processing.
a. Consider machining efficiency: when machining on lathe, the machining allowance is usually large, so the rough machining route must be reasonably arranged to improve the machining efficiency. In practical programming, it is generally not suitable to use cycle command (otherwise, there are too many empty knives with working speed). Shenzhen computer gongs processing a better way is to use a rough car as soon as possible to cut materials, and then fine car.
b. Consider the tip strength: the CNC lathe often uses low strength tools to process small grooves.
3. Flat profile part
a. Direction control of cut in and cut out: radial cut in, with pits left on the workpiece surface; horizontal cut in and cut out, with smooth workpiece surface.
b. Selection of the first approximation method: when the computer gong machine tool which only has the function of line and arc interpolation processes the irregular curve contour, it needs to use the small straight line segment or arc segment to approximate the processed contour (its error is called the first approximation error). When approaching, the Shenzhen computer gong processing should make the workpiece error within the qualified range and the number of program segments less.
What are the classifications of machining centers for large CNC milling machines
There are many kinds of machining centers for large-scale gantry CNC milling machines. Here is a brief introduction:
A horizontal machining center: refers to the machining center with the spindle axis parallel to the workbench, which is mainly suitable for machining box type parts.
B vertical machining center: it refers to the machining center set vertically between the spindle axis and the workbench, which is mainly used for machining complex parts such as plates, plates, molds and small shells.
C multi axis linkage machining center, also known as universal machining center: it refers to the machining center that can control linkage change through the angle between the machining spindle axis and the rotary axis of the worktable to complete complex space surface machining. It is applicable to the machining of impeller rotor, mould, cutting tool and other workpieces with complex space curved surface
