Two-Sided Scanning 
Dedicated for Threaded wrokpieces



1.Two-sided profle scanning function

It obtains profle of object by scanning the surface with T-shaped stylus, then software can calculate the 2D sizes and GD & T based on the profle.

2.Thread scanning function

It can scan ordinary thread ring/plug gauges, tapered thread ring/plug gauges, plain ring/plug gauges, trapezoidal thread, sawtooth thread, multi-head threaded workpieces, lead screws, etc. Then the software can analyze their comprehensive parameters such as internal and external diameter, profle parameters, etc.
