Sharp Internal Corners
Sharp Internal Corners introduces a patent-pending milling head that enables the direct machining of sharp internal corners on standard 3-axis CNC machines through a simple tool change.
Is there a better way?
What if sharp internal corners could be machined directly on a standard 3-axis CNC, even in non-ferrous materials such as wood and plastics?
What if costly or labour-intensive secondary processes could be eliminated and replaced with a simple tool head when small internal radii are required?
But how?
The patent-pending milling tool is designed to integrate directly into existing CNC environments, adopting the familiar form factor of an aggregate spindle-mounted tool head. By aligning closely with conventional angle head attachments, the system enables rapid adoption without requiring machine modifications or workflow disruption.
Tooling that pays back.
Tooling investments are often justified when they reduce labour, setup time, or the need for secondary operations.
Sharp Internal Corners enables this trade-off by delivering new machining capability on standard 3-axis CNC machines through a simple tool change.
The technology has been developed for licensing to established tooling manufacturers, allowing value to be delivered within existing product portfolios.
