Product Description

In the process of conducting impact tests on metal materials, not only high-precision impact testing machines are required, but also properly prepared test specimens. Our company has developed the LY71-UV electric hydraulic broaching machine for impact specimen notches, which can broach notches on the original specimen blank in one pass that fully comply with standards such as GB/T229-2020 "Metallic Materials - Charpy Notch Impact Test Method", ISO-148-2 "Metallic Materials - Charpy Pendulum Impact Test", ASTM E23, and JJG145.

This machine features high precision, long service life, low noise, and an attractive design, making it the preferred model for users across various industries.

Main Uses and Application

      To obtain accurate and reliable test data on the impact resistance of test materials, on the one hand, an impact testing machine with a certain level of precision is required; on the other hand, we have to use various equipment such as lathes, milling machines, planers, bench vices, and grinders, and spend a lot of time preparing qualified specimens.

To meet users' needs and reduce the difficulties in the specimen preparation process, especially the challenges in manufacturing specimen notches, we have developed a hydraulic broaching machine for broaching impact specimen notches, model: LY71-UV, by drawing on various advanced experiences in this field at home and abroad. It fully complies with the requirements for the precision of impact specimen notches specified in GB/T229-2020 "Metallic Materials - Charpy Notch Impact Test Method".

Main Technical Parameters

Working Conditions

     This machine uses a three-phase four-wire 380V 50Hz power supply, and the voltage variation should not exceed ±10% of the rated voltage. The environment should be free from impact, vibration, and corrosive media, and the machine should be installed vertically on a stable foundation. There is a grounding mark next to the power socket at the lower rear of the machine, and the machine is required to be reliably grounded.
