SJ5780-300
The SJ5780-300 from Chotest Technology Inc. is a high-precision profilometer designed for advanced surface roughness and profile analysis. This instrument accurately measures surface texture, waviness, and geometry parameters, providing reliable data for quality control in demanding industrial environments.
Equipped with a highly sensitive measuring system and an extended measuring range, the SJ5780-300 is ideal for inspecting larger parts or complex profiles. Its intuitive analysis software simplifies results interpretation and report generation. It is an effective solution for industries such as automotive, metalworking, mold making, and precision component manufacturing.
Functions
1. Two-sided profile scanning function
It obtains the object's profile by scanning the surface with a T-shaped stylus, then the software can calculate the 2D and GD and T sizes based on the profile.
2. Thread scanning function
It can scan common thread gauges for rings/plugs, tapered thread gauges for rings/plugs, single thread gauges for rings/plugs, trapezoidal threads, sawtooth threads, multi-head threaded workpieces, lead screws, etc. The software can then analyze their integral parameters, such as internal and external diameter, profile parameters, etc.
Applications
Coaxiality of the feed spindle
Rosca caliber
Trapezoidal lead screw
Ball screw
Cylindrical workpiece
