Precision roughness tester JB-8E

JB-8E Precision roughness tester good looks, easy to operate, is a high-precision stylus type surface roughness measuring instrument, which can be on a plane, bevel, outer cylinder, the bore surface, deep groove surface, round roughness of the arc and spherical surface of various parts of the test, and implement a variety of parameters of surface roughness measurements. The instrument can be easily used for bearing raceway roughness measurement. It can be widely used in automobiles, motorcycles, machine tools, bearings, oil pump and nozzle industry factory floor and measurement sector. JB-8E Precision roughness tester main function JB-8E Precision Roughness Tester measure a variety of precision mechanical parts flat, beveled, outer cylinder, the bore surface, deep groove surface, circular surface and spherical variety roughness of the surface of the part to be tested, and implemented a variety of parameters of surface roughness measurements. JB-8E Precision roughness tester main features of an instrument for the company's implementation of GB / T 6062-2002 (eqv ISO3274: 1996) Standard 2003 trial of new products. Each assessment instrument paragraph 2 horizontal sampling of 9600 points, the minimum spacing 0.5μm, 16bit resolution so that the effective sensitivity up to 0.001μm. 3 natural diamond stylus-free linear guide-head 640μm range of new sensors. 4 In addition to Ra, Rz, Rt, Rp, Rpm, more than 20 kinds of parameters, but also provide an internal combustion engine dedicated TP curve parameters. 5 machine has a Gaussian filter and 2CR filter to choose from, and with the curve correction software can measure the roughness on the surface. 6 machine Win operating system interface is very friendly and stable. Roughness measurement software in line with the definition, can be high-precision work; easy to use, the measurement results can be stored in the computer, data, graphics; editing statistical average value of measurement data to facilitate network transmission.
