ISCAR's Diverse Chipformers for Parting Applications

Hello everyone and welcome to TIP TALK from*** ISCAR’s Tec-Center. During this session I would like to explain how to choose the most suitable insert geometry and chipformer for your parting application. ISCAR offers a large variety of chipformers suitable for all types of parting applications. This time we will be focusing on the most popular and common chipformers suitable for general use. I recommend selecting the requested insert according to the workpiece material & type of application. As a general guideline, for soft materials and continuous cuts use an insert which has a positive cutting rake angle. For hard materials and tough applications use an insert which has a negative cutting rake angle. The most common chipbreaker recommended for hard materials and tough applications is a "C" type which has a negative cutting rake angle reinforced with a T-land. A "C" type insert should be the first choice for parting hard steels. This insert is suitable for medium to large part diameters and tough applications including interrupted cuts. It should be used at medium to high feed rates. An additional popular chipbreaker is the "J" type, which has a positive cutting rake angle and therefore assures minimal cutting forces during machining. The "J" type chipformer is recommended for continuous cuts and is a first choice for soft materials such as stainless steel. It should be used for small diameter parts and tubes and recommended for low to medium feeds. To conclude this session, for tough applications and hard materials use a "C" type chipformer which has a reinforced negative cutting edge. For soft materials use a "J" type chipformer which has a positive cutting edge that assures minimal cutting forces.
