Product overview

Think twice about QTM3000 Charpy impact specimen notch making prototype

Product Usage:

Purpose: Used for instrument (wave) impact testing of materials, to determine the impact absorption energy and impact toughness of material samples.

Standards
The sample gap meets the following standard requirements:
GB/T 229-2007 "Metallic Charpy notch impact test method";
ISO148-2008 《Metallic materials- Charpy pendulum impact test》；
ASTM E23-02a "Standard Impact Test Method for Notched Specimens of Metallic Materials";
DVM type specimen in DIN 50 115-1991 "Dimensions and fracture determination of special specimens for impact testing of metallic materials".

Performance characteristics

The puller is made of high-quality W18Cr4V cutting tool alloy material, with reasonable tool parameter design and high service life;
All hydraulic components are sourced from well-known brands, ensuring the reliability and stability of the hydraulic system; Equipped with a lubrication system to supply oil to the cutting edge and guide device of the puller, in order to cool, lubricate, and clean the puller, making the sample notches and surfaces rough during the cutting process

The roughness is guaranteed and the service life of the puller is extended;
The frame skeleton is welded from angle steel, channel steel and other profiles, with a reasonable structural design that conforms to the operator's habits. The panel and other parts are sheet metal structures, which are easy to disassemble and assemble. The surface is treated with spray coating, and the appearance is neat and beautiful;
The electrical components are made of well-known brand products, ensuring the reliability and stability of the equipment.
