Feed Rates for Plastics

DSC_0615“Feed rate” refers to the speed at which material is being “fed” through the machine. It is generally measured in inches per minute or meters per minute, depending on whether the Imperial or metric system is used. The Feed rate is part of the formula used to calculate chip load (size of the chip created in the cutting process). The other parts of the formula are motor speed on the router (rpm) which dictates how many revolutions per minute the tool is turning, and the number of flutes (wings) on the tool. To calculate chipload the formula is Feedrate / (RPM x number of flutes). The most common problem, in regard to incorrect chipload is premature tool wear, tool breakage, most often due to excessive heat buildup and poor material finish/chipping.

Typical chip load range for Plastic Materials

Hard Plastics .004-.016″
Soft Plastics .006-.014″

The smaller the tool diameter, the lower the chip load that applies, will be.

Collets

DSC_0009

Regular replacement of collets should be considered part of good machine maintenance as the condition of your collets will directly reflect upon the tool life as well as quality of finish on your product. Collets that are worn and dirty will create vibration during the cutting process.

CNC Machine Collets

Inspect your cutting tools to see if collet marks are visible on the shank. If so, that is an indication of vibration occurring during the cut and it is time to replace your collet. Although, the vibration can also stem from an imbalanced collet nut or tool holder.

Did you know that in addition to the standard collets with a tolerance of 0.5 mm, GUHDO also offers Premium collets with a tolerance of 0.15 mm?!

Advantages of our “Customize it” Insert Tooling Program for CNC Machines

DSC_1036Advantages of our “Customize-it” system include:

  • No backer plates!  Tool body becomes a dedicated cutter and supports the insert knife, thus improving tool precision!
  • Constant cutting diameter with no re-adjustment do to dimension changes in the tooling
  • Manufactured in strict accordance with European Safety Standards
  • All tool bodies are precision balanced to G2.5 specifications
  • Cost-effective!

DSC_0603

  • Inserts can be sharpened (face-ground)
  • Special carbide grades available depending on application
  • Cost sometimes less than the cost of a carbide-tipped equivalent tool

DSC_0545

  • Excellent tool life!
  • No lengthy lead time!
