MFC cutting

Post by DGF »

Hi, I'm new to CNC and to this forum -
We are routing kitchen sides and components from 18mm MFC
We have tried a Trend Rotatip which was ok for a few passes

Now have a 10mm Compression from Wealden which is better, but looking for advice -

Spindle speed? Feed speed? Climb or Conventional?

We were going in 10mm and then 8.1mm and ramping in, but always get burn on the ramp in - any advice there?
Should we do the cut and then have an offset so it takes a 1mm off final cut?

CNC is 4.5kw - max speed 24,000 and feed rate 8000mm/min

Any advice/guidelines would be much appreciated
David

8m/min @ 12,000-14,000 rpm. Ramp in at full speed.

Increase the plunge rate for the tool bit :lol: :lol:

Either in the tool database or using the edit option for the selected bit on the main toolpath form :lol:
