When material savings are a requirement because of machining expensive materials, large batch productions, or both, it is essential to use the thinnest insert width possible. CoroCut QD parting off and deep grooving tools are now available in smaller insert widths with internal high-pressure coolant to help customers realize production efficiency.

Considered a hidden machining cost, component material waste is an often overlooked production expense. Wider insert blades cut away more material than necessary during each parting off operation with the excess material ending up in the chip bin. Using a thinner insert blade not only wastes less material, but also allows for more parts per bar when parting off using a bar feeder. Realizing this material savings is especially important for those who machine components made of expensive materials, such as heat resistant super alloys (HRSAs). When working with these high-priced materials in high volumes, using a thicker insert blade can be costly.

For small insert widths, insert handling is easily accomplished with the use of the insert cam key. Accompanied with each CoroCut QD, the cam key allows the user to leave the finger of the blade in the open position, allowing for use of both hands for insert positioning. With the turn of the cam key, the new insert clamp design offers improved rigidity for process security. CoroCut QD toolholders are made using the same improved tool steel as the larger width CoroCut QD, resulting in 12 percent higher tensile strength.

As the only product currently on the market that offers over and under coolant in a tool this thin, the CoroCut QD inserts in 0.04”, 0.05” and 0.06” work well for deep cuts and large diameters and for all materials, especially HRSAs.
