Densimet® tool holders.

 

Whether you are riveting, drilling, grinding or lathing: The machining of lightweight, soft materials can often result in oscillations, vibrations or loud noise emissions.

With our vibration-damping tool holders manufactured from Densimet®, quiet, low-vibration machining is not a problem. Due to its tungsten content of over 90 %, our Densimet® alloy has a very high density and modulus of elasticity. The addition of nickel and iron increases the ductility. Armed with these properties, our material is simultaneously rigid and vibration-damping and is therefore ideally suited for use in tool shanks.

Vibration-damping tool holders made of the tungsten alloy Densimet

We supply tool holders made of our tungsten heavy metal alloy Densimet® for boring bars, grinding mandrels, tool shafts and all types of precision tool that require vibration-damping in order to ensure smooth running. We will manufacture these anti-vibration tools entirely in line with your specifications and requirements.

Anti-Vibration boring bars made from Densimet® 176.

 

Thanks to the combination of a high density and a high young‘s modulus, Densimet®176 is the perfect resolution for the ab-sorption of vibrations on overhangs up to 15 times the shaft diameter. Here you see a comparison of the achieveable surface quality with tool holders made of steel and tool holders made of Densimet®176.

This is how it works.

Gladly we will deliver Densimet® 176 rods exactly according to your specifications and tolerances. Contact us, we are happy to submit a quote.

Do you want to machine Densimet® 176 yourself? Let us give you some hints and tipps:

Circular grinding

  • Rough machining: carborundum wheel 4C 60k AJ10
  • Finishing: carborundum wheel 4C 80I AJ10
  • Speed: 25 m/s, copious cooling liquid.

Surface grinding

  • Rough machining: carborundum wheel 37C 36I AJ5
  • Finishing: carborundum wheel 37C 36I AJ8
  • Speed: 20m/s, copious cooling liquid.

Turning and milling

  • Carbide tipped tool. Grade Iso K05 to K20
  • Grinding tapper 0° to 15°, rake angle 5°
  • Feed: from 0.1 to 0.4 mm/rev.
  • Cutting speed from 75 to 120 m/min

Drilling

  • High speed drill, high Co content

Tapping

  • High speed steel taps, high quality material alternate threading

Brazing

  • Quaternary silver or copper based brazing alloy

Directions for shrink fitting

  • Conical, hardened steel
  • Ring diameter: 2 times the shaft diameter
  • Cone length 1.5 times the Densimet 176S shaft diameter
  • Shrinking temperature: 250 °C (yellow to yellow brown)
  • Caution, both the rod and the ring must be machined exactly to the same cone specification (test with engineers blue)
