I am total beginners in this 3D cnc routers matter. So please can you advice me which is right way for realization this kind of production. Right now I have interes to increase commercialize production and I want speed up time of making wood spearguns.įor this product I think I need strong CNC machine for milling operation of hard wood thickness 60mm (teak, mahogany.). Our small wood production is all hand made and it's very slow. I am new in CNC technology and right now I am looking to buy new cnc machine. I think this is the best forum for CNC where you can learn so much. The last pic is of the new pinion stock ready to make into pinions. Then using small clamps to hold the rack tight to the linear rail (not too tight) and in go the bolts.Īlso a couple of pics of the bolts and holes as they were as removed from the machine, I am sure all the swarf isn't from my machining
Then clamp the next section of rack securely to the short section to align it.
Then I clamped a short section of rack against the end of the previous rack so the the racks would be in alignment. I also de-burred the holes on the machine so the rack would sit flat against the surface. The rack got a thorough cleaning and de-burring of all the holes.
To align the rack is reasonably easy, I removed the rack from the machine then cleaned all the metal chips from behind it on the machine. I also need to skim the tops off the teeth on the rack to get a really smooth mesh. Turns out the the pinion for the rack wasn't meshing correctly, I had re-aligned all the rack sections as shown in the pics below, but in the end I got Penfold Transmission Ltd to cut me a new section of matching pinion stock to make new pinions out of. I also have been sorting out some weird patterns on the edges of Mdf and plywood when cutting.
