OreTek MicroMill user's manual

Currently being assembled is a routing system capable of producing a minimum of 27 orthotics per hour. The advantage to this machine, like the patented process itself, is how it works. This machine should be available early in the 3rd quarter of 2007 and will be sold with OreTek Client and a RadScan cast scanner for under $10,000, and will come with the same contract lifetime warranty that all customers of OsiruSoft benefit. Photos and videos will follow shortly as the assembly approaches completion. Unlike most competitors, OsiruSoft hardware is made almost entirely in-house. This alone dramatically reduces costs, which are then passed on to the customer.

The initial full system is 2 computers, an OreTek RadScan cast scanner, and a 4 axis CNC router, all built by OsiruSoft Research and Engineering. This new technology is easily scalable. As your company grows, additional work stations can be added as scanning workstations or micro milling workstations as needed, and without the added expense of new software licenses. Additionally, and as a bonus, cost of manufacturing will likely make it easy to keep all parts of the system in inventory for next day shipping, unless backlogged.

Additional fixturing will be made by the machine itself, purchasing raw materials from sites such as All Metals Inc. and other materials from sites such as McMaster-Carr ®. As many who are already in the industry can attest, the cost of a jig to mill orthotics or similar devices ranges from $1000.00 to $3000.00. The machine being just as precise as a milling machine, can reproduce any part of itself. To those with one non-working MicroMill, this presents only a minor inconvienience, as parts are kept in stock at OsiruSoft. For those with more than one micromill, this means only a minor setup following step by step instructions to replace a faulty part on another machine.

Jig design: Planned for this new MicroMill is to support plates anywhere from 24"x12" to 24"x18, in order to properly support the manufacture of full length soft devices. As the majority of this jig is stationary in the machine, the extra mass of a larger jig is no longer a consideration in terms of labor, nor is it a concern in terms of system load. Once the base production units are in place, other configurations will also be available.

A lower chip load means less stress on the machine.
