trying to improve my board game

**m.marino** · 10-03-2011

Are far as cost on 1mm endmills and any wood based cutting, I would strongly suggest Sorotec, www.sorotec.de as a source that is not extremely expensive and let them know if you are VAT registered. The smaller the diameter the less you can cut in one pass and speed is still and issue. With a 2mm single flue I am cutting at a max of 400mm/min with a cutting area of 1.25mm depth and .75 mm step over.

If you are willing to invest a bit for some tools to help you over the learning curve, I would strongly suggest G-Wizard as it has helped me get a much better grip and understanding of feeds and speeds.

I, in no way benefit from the mention of these companies and am only a very satisfied client of both.

I will try those values for the 2mm bit. What is step over?

Drill-service.co.uk seems fairly reasonable. Does anyone here buy cutting bits off ebay?

Step over is the distance you move the cutter into the material for each subsequent cut. It defines the width of the cut. It is often expressed as a percentage of the cutter diameter.

However for this particular excercise you're just cutting a slot in one pass, so stepover isn't really relevant. Effectively it's 100% stepover though...

I've bought the odd cutter off eBay. Nice and cheap except for the postage and sellers do seem to insist on using fast postage when, personally, I don't think it's always necessary!

Update; cut a few boards, wow this machine is brilliant...broke a couple of bits...

This is now a CNC project so I will post updates elsewhere.

Thanks for all the help, I know I'm going to need loads more too!

As your learning try this link http://www.mycncuk.com/forums/showth...6590#post16590 the 1/8" cutters JohnS showed are superb for the money and at only a £1 almost throw away!!
