chip load guidelines4/19
I have a project looming which will require the use of melamine faced chipboard.Over the years I have routed a lot of MDF,plywood and tooling block,but never this stuff.I intend to use a compression cutter and would greatly appreciate any comments or help regarding speed and feed for 1/2 inch dia or even better chip loads that have worked well.I can do a bit of experimenting,but it would be nice to be somewhere close to begin with.Thanks in advance
If you look online at www.onsrud.com and click on downloads they have a ton of information on chiploads for specific materials, with tool recommendations.
For a 1/2" diameter tool your chipload would be somewhere between .021" to .023"
At 18,000 rpm, using a 2 flute compression bit - you'd calculate your feed rate as follows:
Feed Rate (Inches Per Minute) = RPM x # of cutting edges x chip load
Feed Rate = 18,000 rpm x 2 flutes x .022
Your RPM can be adjusted to bring your feed rate down as desired.
If you are cutting a ton of this material look at Onsrud's Polaris coated bits, we've sold a ton of these with a lot of success. The customers almost always think the coated bits are worth the added cost - tool # 60-169PLR or 60-163PLR
You can call Onsrud and they will direct you to your local dealer to get pricing or more specific help.
We run the vortex 3130xp with good luck.
We arenít exclusive to the melamine and add layed up panels with laminate on both sides and mdf for the backs, so our sheet count per cutter can vary.
There are a lot of good cutters out there, but I would definitely learn the cutting behavior of the different melamine. We use Roseburg and sometimes Funder. The melamine coating between the two require a sight feed rate adjustment.
We've tried quite a variety of bits over the years. We've been using Onsrud's Marathon coated bits (2 flute, 3/8", compression) since they came out. Use their recommended speeds and feeds. Well worth their added price. They hold up much better than uncoated bits when cutting HPL laminated board. Ramp in off the cut line so the up spiral part of the bit doesn't chip the face.
