Special Purpose Machines (SPM)

Alternator Bracket Special Purpose Tapping Machine (SPM)

2- and 4-spindle tapping power units and multi-spindle heads operating simultaneously from 3 independent directions, built for Majd Sanat.

This machine was engineered and manufactured for Majd Sanat Company. In this setup, three tapping power units with matching multi-spindle heads tap the workpiece simultaneously from three separate directions.

For drilling, three multi-spindle heads were engineered to mount onto column drill presses. Drilling proceeds across three sequential stations, followed immediately by simultaneous 3-direction tapping.
