Case Studies

Cog challenge

Business challenge faced – We were asked to produce a new cog from just a ¼ of the original worn equipment.  There was no drawing.

Solution – we used formulas to be able to produce the correct spacing and angles between the teeth. We were then able to produce a CAD file of this to be able to machine new equipment from acetal.

Benefits – Our client were really pleased with the finished article and able to use straight away and restart their production.
