Brookfield LV spindle range chart lists the range values for all LV spindles
SFM is a combination of diameter and the velocity RPM of the material measured in feetperminute as the spindle of a milling machine The faster the spindle turns andor the smaller the diameter the higher the SFM The goal is to tool a job to run the SFM as high as possible to increase hourly part production
If you don’t see a speeds and feeds chart for the product you are working with please contact Rock River Tool at 8003458924 or send us a message through our Contact Us page and we will provide you with feeds and speeds Please include as much information about the material you are machining as possible
The spindle speed must be set so that the tool will be operating at the correct cutting speed To set the proper spindle speed we need to calculate the proper revolution per minute or RPM setting We stated earlier that cutting speed or surface speed would change with the size of the tool
Here’s your comprehensive guide to Feeds and Speeds for Wood together with Tips and Techniques that are specific to cutting wood on a CNC Machine Wood Types When calculating feeds and speeds for wood we generally look at 4 different famillies You can see them in our GWizard Feed and Speed Calculator’s Material menu Just 4 wood types
Feed Rate Spindle Speed RPM Number of Flutes Chip Load inches Spindle Speed Number of flutes Chip Load Answer inchesmin Plunge rate Use a plunge rate of 50 or less of the feed rate So for a feed rate of ftmin use a plunge rate of ftmin or less Plunge depth and stepover
To estimate mill spindle speed and feed rate Calculations use the desired tool diameter number of teeth cutting speed and Chip load which should be chosen based on the specific cutting conditions

This is especially true in CNC machining where the programmer must be able to calculate the spindle speed based on recommended “cutting speeds” usually given in either “Feet Per Minute” FPM US Units or in “Meters Per Minute” MPM Metric Units
Oct 02 2017 · Spindle Speed Cap As shown above the cutter speed RPM is defined by the SFM based on material and the cutter diameter With miniature tooling andor certain materials the speed calculation sometimes yields an unrealistic spindle speed For example a 047” cutter in 6061 aluminum SFM 1000 would return a speed of 81000 RPM
