John A. Webster, Ph.D.

Grinding is a thermally dominated process, meaning a high percentage of process heat initially enters the part before coolant quenches it. Unless the coolant is applied at the correct flow rate and pressure, and the proper input conditions are selected, this process can lead to undesirable rehardening burn, thermal softening and tensile residual stresses.

Through-coolant toolholders: efficient, economical

12/29/2016

Author:

Holly B. Martin

Because through-coolant toolholders eliminate the variances often experienced with external cooling nozzles, the additional cost of such holders, which is sometimes zero, can be easily justified through the reduction of cycle times and improvement of tool life and part quality.

Toolmakers tout nonround coolant orifices

A circular shape provides multiple benefits in the machining world. For example, round inserts are stronger than inserts with any other shape. However, when it comes to coolant channels in cutting tools and toolholders, channels that don’t have circular cross sections can enhance operations.
