CNC Machining Parts Gloss Detection
1. What is the surface gloss of CNC machining parts?
Surface gloss refers to the specular reflection of light on the object surface. Seeing with the naked eye, the surface specular reflection is strong, the gloss is high. Otherwise, the surface specular reflection is weak, the gloss is low. The influencing factors of surface glossiness are related to the physical properties of the surface and the chemical properties of the materials used on the surface. The method of detecting the specular gloss of the object surface requires the use of surface gloss meter.
Gloss is completely different from the concept of "finishness" or "roughness" in the machining industry. Gloss is the property of directional selective reflection on the object surface. Different bright spots appear on the surface or form an image of an object that overlaps the surface. Glossiness is the ability of the surface to reflect light when the object is irradiated by light. It is usually expressed by the reflectivity of the sample in the specular (regular reflection) direction relative to the standard surface multiplied by 100, that is, G = 100R / R.
R in the formula-the reflectivity of the sample surface, / R. ——Reflectivity of standard board. Taking polished black glass as a reference standard plate, the refractive index of sodium D rays is 1.568. The specular gloss for each geometric optical condition is scaled to 105 gloss units.
2. Methods to improve gloss of CNC machining parts
The gloss of the CNC machining parts mainly depends on the performance and rigidity of the machine tool. Generally, the high-speed machine tools can withstand very high speeds. The reasonable precision of the feed cutting and the things that get out of the car are generally very high in appearance. In addition, it depends on the choice of materials and tools.
When turning on a CNC lathe, the rotation speed is faster and the tool is slower. The accuracy depends on your own measurement. There are many factors in this respect, mainly the choice of the three factors of cutting amount, the amount of knife eating, the feed speed and the speed of rotation, The selection of props and sharpening, the choice of materials in the second and finally the cutting fluid Choice.
3. Gloss meter test CNC machining parts
The gloss of CNC machining parts can be tested by using a gloss meter. Linshang is a professional gloss meter manufacturer. Linshang LS192 multi-function gloss meter has the same measurement data as BYK gloss meter and meets the national standards. At the same time, the LS192 multi-function gloss detector has the following characteristics:
Multiple measurement modes –auto mode and manual mode.
Real-time measurement.
Simultaneously display real-time value, maximum value, minimum value, average value and standard deviation value.
Ultra-small design.
The number of storage groups can be set by yourself and a maximum of 99 groups of data can be stored.
The gloss meter conforms to the standards of the National Measurement Verification Regulation JJG 696 first-class gloss meter.
Connect to the computer to expand more functions and generate professional reports in real time.
