The machine running a tapping cycle

Overview

The client had a tapping step that was done by hand, part after part. The brief was to automate it so an operator no longer had to feed, tap and remove each component. I designed the machine, produced its models and drawings, and manufactured and assembled it.

How It Works

Servo-driven tapping head: a servo drives the tapping head along a linear axis, for controlled feed into the part and a repeatable stroke.
Pneumatic ejection: a pneumatic cylinder pushes the finished part out at the end of each cycle, ready for the next one.
Modular frame: an aluminium extrusion frame keeps the machine rigid and easy to adjust during commissioning.
Custom brackets and plates: designed in SolidWorks and Fusion 360, with 2D drawings for manufacturing.

Build

Stepper-driven vertical head with lead screw, guide rods and a collet-held tool on an extrusion frame — Head assembly: lead screw, twin guide rods and collet-held tool on an extrusion frame

Outcome

The machine cut out manual intervention in the tapping step and reduced cycle time for the client's repetitive operation.
