Product introduction:
SRA-2 contour roughness tester is a precision measuring instrument which combines two parts into one. It is widely used in machining, automobile, bearing, machine tool, mold, precision alloy, optical processing and other industries.The instrument drive box provides high-precision linear reference guide rail with different specifications of 100, 120 and 150 mm. The sensor moves in a straight line along the guide rail.Thus, X coordinate measurement unit is established, and differential electric sensors of two specifications from 10mm to 20mm are adopted in the z-axis direction.Can be made through the horizontal adjustment knob driving box ±10 degrees of high level, and respectively through the operation of the control box key or software interface for the movement of the horizontal and vertical direction, shape can be arbitrary scaling up for sampling and instruments with special computer and measurement software, measurement under WindownXP operating system software intuitive and convenient operation, rich functions, high accuracy, good stability, convenient and print and file.The roughness and contour shape parameters of various precision mechanical parts can be measured.The fitting method can be used to evaluate the radius, Angle treatment, circle treatment, point line treatment, Angle and distance between the center of two circles.Thus, shape parameters such as straightness, convexity, groove center distance, inclination, groove depth, groove width, groove edge distance, groove center distance perpendicular, horizontal distance, and step can be measured.
