I have encountered unexpected problem with my Nomad 883 Pro. I spent last two days cutting some aluminum brackets for a project and today, after about 8 successful cuts I had tool dug into a material and ceased. After this accident I couldn’t make a single successful cut for two days. I have switched between 5 different pieces of stock material. I have replaced tool for new #102 bit and it still gets jammed diving nearly 2 mm into material in process on the first pass.
I use 6 mm thick 6061 aluminum stock.
Nomad #102 flat tip bit
Depth of cut per pass is 0.15 mm
Milling speed is 250 mm/min
Spindle 10000 rpm
I use sprayer to cool down the bit in process and there was always some water covering the cut.
Is there a possibility that something got lose in the machine itself? Z axis stepper for example? It still feels rigid and I can’t feel any play. Material is also securely fastened to the table with bolted clapms. My thinking is that something was yielding to allow the tool such a deep dive into the part. Trying to narrow down what it could be.
