LIH JAAN PRECISION MACHINERY CO., LTD.

Features

Superior Accuracy for Threads

Actual Measurement Accuracy Report

Extracted from customer machine inspection accuracy report The workpiece three-meter ball screw meets C3 accuracy

Wheel Dressing Axis (A/B)

Wheel dressing axis (A/B) is mounted on the wheelhead, allowing in-place dressing when the wheelhead is rotated for grinding an angled thread. This eliminates the need to reset the wheel head position, significantly reducing adjustment time.

Various dressing methods to meet diverse needs.

For mass production, a forming dresser ensures contour accuracy and speeds up dressing time. For small-batch, diverse machining, a single-point dresser can be used, with the program generating multiple dressing paths to enhance flexibility and accommodate various workpieces.

CNC Intelligent Precision Control, with LIH JAAN own Dialogue Interface

Easy Operation & Efficient Smart Grinding – Generates complex grinding paths Pair with variety controller brands FANUC, Siemens, SYNTEC and so on.
