"Datum Point" Technology... for speedy job changeovers

"Datum Point" tooling for screw machines, whereby a family of similar parts can be made by simply changing the form tool, has been made simple with the introduction of Somma's patented "Resharpenable Quick Change" Insert Type Form Tool Holders.

Once the insert holder is set to the proper center height and lateral location for one job, it never has to be moved. All that is necessary when changing to a new job is to change the insert.

The form on each insert is calculated so that it will produce the diameters and lengths as required for each job and the inserts are mounted into a pocket in the toolholder of controlled width and depth, in relation to which the form of each insert is calculated.
