The GenNotch 4000 Series is a dual-chamber motorized broaching / notching machine designed for Charpy Test notch specimens. This floor-mounted self-contained unit is equipped with a user-friendly interface for ease of operation. The GenNotch 4000 is designed for cutting Charpy and Izod V-type and U-type notches according to the latest industry standards, delivering the highest quality notching samples equivalent to that of a milling machine.
The GenNotch 4000 is able to prepare two specimens at one time due to its dual broaching system in mere seconds with exceptional accuracy and repeatability every time. The state-of-the art manufactured broaching knives can be purchased based on your preferred V or U types specimen preparation needs. The standard knives have been upgraded to prepare specimens up to 48 HRC.
Our spare parts and consumables offering for the Specimen Notching & Broaching Machine includes precision-ground notching and broaching knives manufactured to meet the requirements of ASTM E23. These cutting knives are suitable for materials across a wide hardness range, from 34 HRC up to 48 HRC. Designed for performance and long service life, many knives are cross-compatible with other systems; however, we recommend confirming compatibility with your technical consultant prior to purchase to ensure the correct tooling and optimal performance for your specific application.

GenNotch 4000 motorized specimen notching system complies virtually all North American and European standards including ASTM, E23-02a, EN10045, ISO148, ISO083, DIN 50115 and more.
The notching knives are custom designed with W18Cr4V material to guarantee the highest level of rigidity and slow wearable. Each impact broaching knive can be used approximately 20000 times.
The quoted system comes as a turnkey solution to include at least 2 specimen notching knives at no additional cost. Additional knives can be purchased separately.
Recently, GenNotch 4000 Notching System has been upgraded allowing the cutting capabilities of up to 60HRC.
Please specify the cutting requirements to your quality consultants for the most optimal impact V and U notching cutting solution for you.
Shavings and debris are simply collected on top of the machine. A simple brush or magnet is enough to clean the machine and keep it in top condition.
The NextGen broaching system requires little to no maintenance! The GenNotch system is equipped with an internal lubricating oil circulation system to reduce operator involvement on maintenance requirements.
The GenNotch is equipped with a dual broaching system and can prepare two samples in one pass!
The GenNotch 4000 series is a floor standing unit which is 43cm x 75cm x 125cm tall and weighs 200kg.
NextGen offers a variety of broaching tools to cover all international industry standards such as the Charpy and Izod V-type notch along with the U type notch as well!
A simple power requirement is all that is required to connect the GenNotch 4000 series Charpy notch broaching machine. A 3-phase, 5-line power requirement is needed. AC 380V 50/60Hz.
Absolutely! With a simple modification, both standard and sub-size Charpy and Izod Impact specimens can be prepared according to specification.
While we recommend an environment with laboratory standards, the GenNotch is robust and built to last for decades for Charpy V-notch and Charpy U-notch sample preparations.
