Princeton Tool Offers Post Cast Machining Services
P
rinceton Tool specializes in foundry support services with a focus in the Aerospace and Industrial Gas
Turbine industries, supporting product operations in both the pre-cast and the post-cast state.
When subsequent machining is needed on your castings, their sales and engineering team will map out a machining plan for your product to flow. The process of mapping the machining plan and working closely with the product engineer limits program delays. This process also ensures the most efficient machining plan is decided, to save time and money once in production.

tracking system and pushed to the first operation on the router card. In most cases, the first operation is completed through waterjet which is a safe and fast way of removing large amounts of material while reclaiming high valued raw material for customers, previously lost to cut off and grinding equipment.
Once the casting has processed
through waterjet, the next rough operation is grinding also known as “snag”. This allows for a quick removal of material to a finish state, where casting geometry allows it. If machine areas are restricted or have contour, EDM and CNC operations would be required for the removal of unwanted material. This allows for precision and certainty in complex and contoured areas. In some cases, not all previously mentioned
operations will be required. An
example of this would be product they manufacture direct from raw material for their aerospace OEM customers.
such
Sophisticated machining as EDM (Electrical
options, Discharge
Machining), is an efficient method of metal removal to address complex or critical areas. Electrodes used to perform these operations are designed by our onsite NPI (new product introduction) team, programmed and machined onsite at each of the Princeton Tool facilities. Current EDM operations are supported by over 70 pieces of equipment staffed around the clock. Equipment can accommodate parts in excess of 4’ with a surface finish from recast less a thousandth. This recast can be eliminated with a single blast operation.
