Sand blasting is a process of cleaning and roughening the surface of the substrate by the impact of high-speed sand flow, and has been widely used in many industrial fields. The surface of many CNC parts in daily life is not a mirror surface, but a somewhat rough "frosted" effect. This "textured" effect is liked by many people. This is a very common process in metal finishing called sandblasting.
The accuracy of CNC machining is the degree to which the three geometric parameters of the actual size, shape, and position of the machined part surface conform to the ideal geometric parameters required by the drawings. The ideal geometric parameters, in terms of size, are the average size; in terms of surface geometry, they are circles, cylinders, planes, cones, and straight lines; for the mutual position between surfaces, they are parallel and perpendicular , coaxial, symmetrical, etc.
The design drawing of CNC machining parts is one of the main bases for product processing in an enterprise. The design drawing of parts has a very important relationship with the precision and quality of CNC machining products.
In the field of CNC machining parts industry, plastics are often used as raw materials for further processing. Now there are many types of plastics on the market, so what kind of plastic should I choose when CNC machining parts?
High-speed CNC engraving machining is widely used in the machining of precision CNC parts. In daily use, some problems will inevitably occur. Today, VMT CNC machining summarizes some of the problems that are easy to occur in the process of high-speed CNC engraving and machining. Let's take a look Which are there?
Summary of CNC parts processing technical requirements, tolerance requirements, and assembly requirements!
A basic method of deep hole drilling machining, drilling is often carried out on drilling machines and lathes, and can also be carried out on boring machines or milling machines. The machining accuracy of drilling is low, generally only reaching IT10, and the surface roughness is generally 12.5-6.3 μm. After drilling, reaming and reaming are often used for semi-finishing and finishing.
During the execution of a 3-axis CNC milling program, the two rotary axes of the 5-axis machine tool are used to fix the cutting tool in an inclined position, and the name of the 3+2 CNC machining technology also comes from this, which is also called the positioning 5-axis machine tool.
