4 Tips for CNC Milling Machines


If you’ve just purchased a new or used CNC machine, you might be tempted to jump right in and start milling. While it’s great to be excited about you’re the possibilities of your CNC Machine, it’s important to take a step back and make sure you’re ready. Here are 5 tips for a successful CNC Machines:

Don’t use stainless steel – Stainless steel and other difficult materials are best saved for when you’ve built up some experience. We recommend starting out with brass or aluminum and building up to mild steel. When you’ve mastered executing perfect cuts on these types of metals you can feel confident tearing into some stainless steel.

Get a misting setup – Some machines come with flood coolant, but if you don’t have one now, make sure you have a misting setup. Keeping an eye out for chip buildup will preserve the life of your cutters and avoid breakage.

Don’t skimp on the cutters – While you don’t need the highest quality aerospace cutters on the market, you also don’t want to settle for some low quality, generic, imported cutters. Simply knowing that you have a decent cutter can rule out a major variable when it comes to determining where you might be going wrong with your cuts.

Get a quality visa and clamping kit – Work-holding is extremely important. If you don’t spring for a decent vise your workpiece will likely shift without your knowledge, leaving you questioning what went wrong. And remember, a good vise is useless without a clamping kit to hold it to your table.
