JB-4C 精密粗糙度测试仪Precision Surface Roughness MeterJB-4C精密粗糙度仪是一种高精度触针式表面粗糙度测量仪器，该仪器可对平面，斜面，外圆柱面，内孔表面，深槽表面，圆弧面和球面等各种零件表面的粗糙度进行测试，并实现表面粗糙度的多种参数测量。仪器可方便地用于轴承滚道粗糙度的测量。仪器配有电脑及专用测量软件，运用先进的无噪声机械定位装置，可选定被测零件的不同位置，设定各种测量长度进行自动测量，评定段内采样数据达3000个点。所有的测量数据和曲线可在屏幕显示或打印输出，所以在汽车配套行业、机械、模具加工、科研单位、大专院校等各大行业中广泛使用。仪器符合国家标准GB/T3505-2000, GB/T6062-2001, GB/T10610-1998, 以及国际标准ISO5436, ISO11562的要求。JB-4C Roughness Meter is a probe-style profile measuring instrument. It is applicable to measure surface of various types of parts, such as planar, incline, cylinder, circular and spherical parts, grooves and bores. It is also applicable for measuring roughness of roll path, either outer or inner, of bearings.A precision locating mechanism is provided to ensure different type of parts to be adjusted into proper position of measurement.The profile shape of the test piece is dynamically displayed on the screen and the portion to be tested is selected quickly and conveniently. All the evaluated roughness parameters, the profile curve and the tp curve are display on the screen clearly.It is in compliance with China Standards GB/T3505-2000, GB/T6062-2001, GB/T10610-1998, and ISO5436, ISO11562.■特点介绍■技术规格型号TypeJB-4C测试参数Evaluation ParametersRa,,Rz,Rt,RS,RSm,Rp,Rv,Rmax,Rq,D,Pt台阶Lr,Ln,RSk,RΔq,Δa,λq,λa,R3t,Rt1,Rt2,Rt3,RT4,rt5等，Rmr(Tp)曲线粗糙度测量范围Roughness rangeRa 0.01 – 50 µm取样长度Sampling lengthL: 0.08 ,0.25, 0.8, 2.5 mm评定长度Evaluation lengthLn: 1L, 2L, 3L, 4L, 5L可任选Selectable仪器评定取样Sampling points4000点分辨率Resolution0.001 µm示值误差Indication error± 5 %测量重复性Repetition error± 3 %测量工件最大高度Max. specimen height300mm传感器可测Application平面、斜面、内孔表面、外圆柱面、深槽表面，圆弧面，球面等各种零件的表面粗糙度planar, incline, cylinder, circular and spherical parts, grooves and bores.天然金刚石触针Probe标准型Standard type,高度Height<8mm小孔型Special probe for small bore触针半径radium:2um,  pressure测力: 4 mN驱动箱的滑行速度Traverse speed2mm/s驱动箱升降形式Traverse U/D mode自动升降Auto移动速度Scanning speed0.5 mm/sec线性区Linear range垂向Vertical  640 um台阶和Pt测量范围Thickness and Pt range100 um分辨力Resolution0.1 um轴向测量范围Longitudinal range60 mm轮廓图形Profile graph直接轮廓，滤波轮廓Macro profile,filter profile轮廓图形的X、Y放大比X、Y magnification自动选定Auto mode滤波器FilterISO 2CR滤波器ISO 2CR Filters小孔测量范围Measurable range of bore≥ Ø5 mmX-Y工作台X-Y stage旋转角度Rotation ±10?摆动范围Declination ±10?X-Y移动范围Adjustment 15 mm轴承内外圈尺寸For measurement of bearing内圈最大外径Max. outer dia. of inner ring 280mm外圈最小孔径Min. inner dia. of outer ring 12mm厚度Thickness：≤160 mm打印纸规格Printing paperA4纸操作系统Operation SystemWinXP标准配件，附件Standard parts & attachments支柱及大理石底座Column & Base控制器Control box驱动装置Driving unit传感器TransducerX-Y工作台X-Y stage,V型台V-stage-标准型触针Standard type probe小孔型触针Special probe for small bore粗糙度样板Glass roughness sample计算机，打印机Computer & printer仪器电源Power supply:220 VAC±10%, 50Hz大理石工作台尺寸Granite base700×400×100mm仪器毛重Gross weight100 kg
