CadCam production of orthotics and Techno-isel machines

This is pretty much just addressed to users of Techno-ISEL products to produce orthotics.

I've recently designed a replacement bearing housing for the axis of any techno machine that use the spherical bearing design, which will enable replacement with the correct type of bearing, angular contact bearings. More information on this project will be available in the LC3024 album on my facebook account.

Once my 2 current installations using the LC3024 model are completed, I'll make this drop in replacement available to anyone interested, covering materials and modest shop hours expenses. As many know, material tolerances are mostly dependent on backlash (slop in the travels), at minimum, replacing the Z-axis bearings would improve the quality of product coming from these machines. While this improvement doesn't address other tolerance errors, such as stress relief and warping that occurs when one side of the plastic is cut, it will at minimum mitigate the machine itself as a source of flaws in manufacturing.

 

This is the first prototype, geometrically identical in terms of bearing placements. Total manufacturing time, 28.7 minutes.

 

:good:
Bravo!
We were also noticing its (the Techno's) shortcomings!:bang:

 

Switching from machining centers to routers comes with its ups and downs. The main upside is a 4 week lead time on delivery to my customers, ready to run (Turn-key). The down side is precision, but reduced chipload and tightening up the machine tolerances mitigates the difference . Then there's the cost savings.


I've had thedse issues solve from a software and hardware perspective for months now. OreTek MicroMill code is 100% natively compatible with anything Techno and servos, which was probably one of my best business decisions this year.

Here's my latest work with this machine on Facebook and on cncZone

What's not shown is an extra spacer to compensate for the change in length of the bearings compared to the spherical cloister. I just used an old inner race from a similar bearing, and ultimately I'll just buy the spacers.

 

For those interested in this thread, I've uploaded a video of this machine with all of its enhancements in place. It now rivals the more expensive machines, (haus, fadal, Hurco) in terms of quality and performance. It cost my customer very little in hardware to start his business as a manufacturing laboratory, already producing more than 400 pair per month, which is less than 50% of the system capacity per shift. Higher quality, lower entry cost, lower prices to end user. All in all, a big win.

Used techno-isel machine, $6500.00
Jig $200.00
Replacement thrust bearings, $30.00
OreTek RadScan system, $1200.00.
3 servo motors, $1100.00

Breaking the $10K price barrier, priceless.

Ironicly, the smallest machine is actually the best to use, and least expensive, and will be proven over the coming month. My next system will be the LC3024 table top version, which promises to be even faster than the most recent project, at least by 20%. The next version will springload the opposite end of the ball screw to improve stability, adding another 30% velocity improvement.

Unfinished product from my last project is also viewable from my LC3024 facebook album
