SRT-7150 Surface Roughness Contour Graph waviness Profilometer
Integrated Testing Machine
SRT-7150 is an integrated measuring machine equipment for surface
roughness and contour measurement.
The surface roughness and profile of various workpieces are
measured and analyzed by using high precision grating measurement
system, high precision grinding guide rail, high performance
non-contact linear motor, high performance roughness measurement
module, high performance computer control system technology and
perfect multi-functional software.
The device can measure various parameters of various mechanical
parts, such as plain line and cross section profile parameters,
surface waviness parameters, roughness parameters and so on.
It can measure the straightness, inclination, angle processing,
circle processing ( distance from straight line to tangent line,
distance from circle center to circle center, radius of arc,
distance from intersection point to circle center, distance from
circle center to straight line ), point line processing ( distance
from intersection point to straight line, distance from
intersection point to circle center, intersection point of two
straight lines, distance from intersection point to intersection
point ), logarithmic curve, groove width, groove depth, groove edge
distance, groove center distance, inclination, horizontal distance,
vertical distance and other shape parameters of various parts.
It is suitable for bearing industry, mechanical processing,
automobile, motorcycle, precision hardware, precision tools, molds,
tools, optical components and other industries.
