Application

In notched impact testing of materials, the machining of the V-notch (or U-notch) is crucial for the success of the test. This broaching machine provides an ideal solution that guarantees 100% qualified specimen production, producing V-notches with a depth of 2mm and U-notches with depths of 2mm, 3mm, and 5mm. This broaching machine is a leading product in China, developed based on the actual needs of numerous domestic users and incorporating international experience in this field.

This broaching machine is driven by a motor and screw, supported by high-precision square rails, with a tight-fitting slider, ensuring smooth and reliable operation, good wear resistance, and low noise. It is suitable for testing institutions with high testing volumes and offers low maintenance costs. V-shaped or U-shaped broaches can be configured according to user requirements. The sample notch is formed in one pass, successfully producing a standard sample notch in a single operation. Each notch processing session takes only 10 seconds, making operation simple and reliable. The broaches are precision-manufactured using special materials and processes, resulting in high hardness, excellent wear resistance, and a long service life. The machined V-shaped or U-shaped notches meet the requirements of GB229-2020, ASTM E23, ISO148, ISO0083, and other domestic and international standards, and are easy to replace.

The broaches are made of special steel, exhibiting high hardness and excellent wear resistance. Due to the one-pass broaching process, the machining consistency is excellent, ensuring 100% (qualified/compliant) sample notches.

In summary, this broaching machine is an essential piece of specialized equipment for physical and chemical testing laboratories in metallurgy, boiler and pressure vessel manufacturing, automotive and shipbuilding, engineering machinery manufacturing, and scientific research departments.
