Re: Felder High Speed Router Spindle 424-111
开云体育My machine has generic guide that is based upon recommended feed rate between 40 & 70m/s lower feed rate than 40m/s can result in kickback and higher than 75m/s can cause damage to tooling not to mention excessive wear if the tool continues to run w/o damage. There is a graph in the manual that further refined this with inclusion of cutter length b I know this does not cover router spindle. Has anyone seen a graph like above from Felder for router spindle? Imran On Dec 28, 2020, at 12:02 PM, Joe Jensen <joe.jensen@...> wrote:

On Behalf Of Eric Janson ? This spindle works at 15,000 rpm, so for smaller- diameter router bits the cutting edge speed is kind of low. For larger bits and deeper cuts, it works great, having many HP behind it, and is as close to totally?vibration- free as you are going to get. Changing spindles is not difficult, but changing back and forth is a pain, so my cast- iron router table is my go- to for that sort of work unless I feel I really need what the Felder spindle brings.

Re: Machinery Choice and Workshop Layout
how it is setup now, I cant pull it all the way back but it will allow me to cut 8x4 sheet. 3200 will be fine, I got this 3800mm slider cos it was a factory shutdown auction. otherwise I would have settled for something no bigger than 2500mm. I dont need the lengths beyond 2500mm.
You could place the bandsaw like how I placed mine, nicely tucked in the dead zone behind the panel saw.? not to mention my extractor takes out a fairly big chunk of space in the workshop!? |

Both the A951L and D963 have a shorter corner and come with an adjusting screw already installed to level the machine.?Does this help in moving the machine? i.e. getting a pallet jack under which otherwise be too wide? Imran |
