Make CNC thread grinding machine acting more smart--- JHT-4010CNC with
"Smart Machine Function"

For JAINNHER's new designed JHT-4010CNC which just received the "Taiwan Excellent Award 2020". You probably wonder what's the special point of JHT-4010CNC? Here comes the solution--- "Smart Machine Function".

"Smart Machine Function" is our own design and gets a patent from "Taiwan Intellectual Property Office" already. Equipping with "Smart Machine Function" can help technicians monitor JHT-4010 through industrial PC more easily:

(A) Status monitoring: spindle balancing system & abnormal sound detection.

(B) Collect the warm up / grinding vibration / operation journal for data analyzing

(C) Built-in intelligent modules: Gap detection between grinding wheel and workpiece.

This module also can optimize the grinding process parameter. The ultimate goal is to improve processing behavior, to enhance grinding accuracy, to increase production efficiency and to save the costs.
