Escomatic D6S-R

Escomatic D6S-R Image The following lesson outline details the tasks needed to be a machinist on an Escomatic automatic screw machine. Some of these tasks require the trainee to explain how something works to insure they have the required understanding of the processes and are not simply memorizing procedures. All of the tasks listed will be a part of the Performance Test within each lesson. To learn more about these tests and the training process itself, see the Philosophy section.

These fifteen lessons will teach the trainee to perform a complete setup of the Escomatic D6-R or D6S-R. In addition, the trainee will learn to operate the machine and maintain the quality of the finished parts during operation.
