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. |
