As we all know, the foam mill cutting tool is an important part of the foam CNC machine that actually cuts and shapes the foam. We use a foam mill cutter on a CNC router, which can guarantee high precision, ensuring that the final product matches the intended design and versatility, improving the working Efficiency.

Here we’ll introduce how to choose a proper foam bit for your project and how to maintain the foam bits.

1. How to choose the suitable foam bits

1. Choose the foam bits according to the different functions. 

Such as you use for carving, bottom clearing, finish carving, groove a hole, etc. which correspond to different bits. Here we can supply you Ballnose Long Foam Router Bits, Flat End Long Foam Router Bits, Conical Ball End Tapered Foam Mill Bits, and bottom clearing bits.

2.  Accuracy and Speed of Cutting

The main function foam cutter is to cut quickly with high precision. So when you purchase a foam mill cutter, evaluate the precision for your need, also you need to know the speed of the machine. 

3. Foam Types

Foams vary significantly, such as Styrofoam, EVA, EPS foam, polyurethane foam, Polyfoam, Eva foam, plastic, etc. One foam mill cutter does not all operate effectively with every type. Whether you're using polyurethane foam or high-pressure foaming, you need to find a suitable CNC foam bit for your foam.

the CNC foam router machine's size and its portability options. A machine that integrates well into your environment enhances overall workflow efficiency.

5.Surface requirements of the foam product

The more flutes there are, the better the surface finish quality will be. Cutting quality Machines that can produce more precise cuts with smoother edges

2. Daily maintenance

Maintenance of CNC foam mill cutters is also a very important issue. 

When the work of the foam router machine is completed, the CNC foam mill bits should be collected well; the foam mill cutters should be oiled to prevent moisture and rust when next used, make sure to put them in different categories, for example, ballnose foam bit is in one category, flat end mill bit is in one category, conical foam bits are in one category... 

1. Collet should be checked before using. It is not allowed if the collet is cross-section, worn, or not round enough, otherwise, it will cause the foam mill cutter to vibrate, and influence the bit's life.

2. Check the toughness of the foam mill bits frequently. The blunt foam mill cutter should be replaced immediately because it does not only have a bad carving effect. 

3. Workpiece thickness can not exceed the cutting length of foam mill bits.

4. Different cutter materials should have different cutting speeds, I recommend you consult a foam bits supplier. RicoCNC can try our best to guide you to use the right cutting bit to cut your foam with proper speed.

5. The cutting speed should be balanced, and the speed should be as consistent as possible to achieve better results. The cutting process cannot be stopped.
