Irregular shaped holes of virtually all types and sizes may be produced economically by broaching. Colonial has experience with a number of special internal and external shapes, some of which are:
Concave Broaches - used primarily to broach seat sectors. We have a large amount of engineering and manufacturing experience with these types tools. From in house design to final inspection and tryout, Colonial can ensure that you receive tools that produce parts to your part specifications.
Turbine Disc & Blades – the shape is generally referred to as Christmas Tree, Fur Tree or Pine Tree form. Broaching is the only method that can cut these complex shapes with high precision due to the types of high temperature heat-resistant alloys used for these turbines.
The accuracy and rigidity of the broaching machine (see our CNC Broaching Machines), broach holder as well as the broach must be closely scrutinized for this process to be efficient. All are sufficient reasons to choose Colonial for your turnkey turbine disc requirements.
