Features of the equipment

Host characteristics

Aluminum alloy casing and high-precision ball screw pair make the transmission more stable. The whole machine has high rigidity and runs smoothly;
Large experimental width to meet the needs of most customers;
Taiwan exchange servo motor drive, high precision, fast response;
High precision sensor with high accuracy and good stability.

The middle crossbeam is guided by four guide rods and a graphite self-lubricating sleeve. The strong guiding light bar increases the lateral rigidity of the equipment, ensuring linear motion of the crossbeam. It can achieve precise alignment of cross shaped streets, reduce differences in measurement data, and produce good overall accuracy;

Controller features

The measurement resolution of force and deformation reaches 1/300000 of the full range;
