Product Introduction
JB-5C profile roughness tester is a precision measuring instrument that combines two into one, widely used in industries such as mechanical processing, automotive, bearings, machine tools, molds, precision hardware, optical processing, etc. The instrument drive box provides high-precision linear reference rails with different specifications of travel of 100, 120, and 150 millimeters. The sensors move in a straight line along the rails, and the displacement is collected using precision grating displacement sensors. Thus, the X coordinate measurement unit is established, and differential inductance sensors with two specifications from 10mm to 20mm are used in the Z-axis direction. The drive box can be adjusted horizontally by ± 10 degrees through the horizontal adjustment knob, and can be moved horizontally and vertically through the operation keys or software interface of the control box. The sampling shape can be enlarged proportionally at will. The instrument is equipped with a computer and dedicated measurement software. The measurement software under the WINDOWS XP operating system is intuitive and convenient to operate, with rich functions, high accuracy, good stability, and easy printing output and file saving.
It can measure the roughness and contour shape parameters of various precision mechanical parts. The fitting method can be used to evaluate radius, angle processing, circle processing, point and line processing, as well as the angle and distance between the centers of two circles. Thus, shape parameters such as straightness, convexity, groove center distance, inclination, groove depth, groove width, groove edge distance, groove center distance vertical distance, horizontal distance, and steps can be measured.
This instrument can now compare its performance with imported instruments from abroad, and all indicators have reached international standards. The instrument complies with the national standard GB/T3505-2000, GB/T6062-2001, GB/T10610-1998, And the international standard ISO5436, Requirements of ISO11562 and ISO4287. Please refer to the technical parameters for detailed indicators.
