Southeast Tool, Inc. Tips Click Below for Safety info, click below Solid Carbide Spirals Some of the problems that users experience with Solid Carbide Spirals 1. Feed Rate---too slow a feed rate can be just as bad as too high a feed rate. Contact SE Tool to aid in determining your proper feed rate. mailto:router@southeasttool.com 2. Collet Condition--always inspect the collets and the shanks of the tools for collet wear. This is one of the biggest causes of tool breakage. Collet's should be changed 3-4 times a year at least, more if the machine has crashed, running high feed rates, or running more than 1 shift a day. 3. Hold Down--make sure that your hold down system is adequate. If you suspect movement, always use a downcut spiral to aid in the holding the part this is especially true in cutting small parts. 4. Spindle bearings--from time to time you need to check the spindle bearings for runout. This is very critical on CNC machines. 5. Material--take a look at the material being ran and the tool you are trying to use. If you need help, please contact us. mailto:router@southeasttool.com
Formula for Feed rate's Keep in mind that this is only a starting point. Some users may be able to go above the suggested feed rate and some may not be able to achieve the feed rate's This is only one of many ways to find the chipload 300 (IPM) / 18,000 RPM's = .016 chipload This means that the tool is removing .016 of material per 1 rotation If you have a 2 flute tool, you would divide the .016 by 2 for a chipload per flute or wing. ( .016 / 2 = .008 per flute) The more you increase the chipload the more the finish is going to decrease. IPM (inches per minute) RPM (Revolutions per minute)
