Anviloy® 3D
Anviloy® 3D describes a group of Anviloy®-Products with complex internal cooling channels which up to know were only possible to produce by additive manufacturing or 3D printing.
In combination with the already 4-times higher thermal conductivity of the Anviloy®-Products, Anviloy® 3D provides by its conformal cooling design incredible cooling rates.
- Umatched cooling rates
- Significant improvement of wear resistance
- Remarkable reduction of sticking
Anviloy® Weld Rod
The product group Anviloy® Weld Rod contains filler metals as rods and even wires. They are used to repair, armor or coat dies made of tool steel or Anviloy®. It is also used to create weld connections of Anviloy®-Products e.g. like for threaded or welded inserts.
This is done by melting Anviloy® Weld Rod in a simple TIG-arc and apply it to a work piece.
- Significant increase in wear resistance
- Reduction of soldering
- Repair Welding provides increased lifetime
Anviloy® C
Anviloy® C are Anviloy®-Products with a special Surface treatment. This complicated treatment creates an extremely hard surface without any geometrical deformation. The hardness can be increased by up to 6-times without any negative effect on the thermal conductivity.
The results of this huge increase in hardness is a significant improvement of wear resistance and remarkable reduction of sticking.
- Huge increase in hardness
- Significant improvement of wear resistance
- Remarkable reduction of sticking
Machining Recommendations
Turning
-
All turning tasks - inside and outside - can be accomplished with common tools made from tungsten carbide listed in the ISO groups of machine cuttings K 05 to K 20. Using tungsten carbide turning tools, cuts without chamfer with a setting angle of 6° and a face angle of 6° - 12° should be selected. For cutting, positive plates are to be preferred with chip breaker without chamfers. Cutting speeds of 80 - 120 m/min can be achieved. Also, High Speed Turning is possible. Cooling agents are not necessary.
Drilling
-
For this treatment are drills made from high-speed steel (preferably material NR. 1.3342 or 1.3343) or tungsten carbide of the ISO group of machine cuttings K 10 suitably. The tip angle of the drill should be 120°. Depending on the choice of the tool material cutting speeds from 20 to 80 m/min are possible. Since no cooling agent is used, the drilling made of high-speed steel needs often to be ventilated, in order not to let cutting edge of the drill rise to a temperature over 550°C.
Milling
-
Knife heads with positive indexable inserts made from tungsten carbide of the groups of ISO machine cuttings of K 10 K 20 and/or P 20 to P 30 proved to be very suitable. With an angle of the major cutting edge of 80° the face angle of the indexable insert should be 6° - 10°. Likewise, the angles of inclination should be 6° and the setting angle 6°. As cutting speed 80 - 120 m/min is recommended. High speed Milling is possible. No cooling agent is used.
Grinding
-
For sharpening Tungsten alloys ceramically bound grinding wheels made of silicon carbide can be used. With a granulation of 50 - 120 the degree of hardness of the disk should be H to K. For cooling of the disk and reliable clearing of the splinters the grinding area must be rinsed with a strong cooling agent jet. The cooling agent can be a mixture of water and a commercial additive.
Electrical discharge machining (EDM)
-
Generally, all here mentioned metals can be machined by spark eroding. To machine these high melting metals, you have to use high melting electrode materials. We recommend TUCOMET®80 and W90NiCu which can be ordered from us. Please take care that the electrode is used as a cathode.
Bonding
-
All Anviloy® alloys can be well hard brazed. As silver solder the silver solder 8427 with 840°C and 8449 with 690°C work temperature work satisfactorily. In special cases Anviloy® alloys can be connected also by friction welding with steel, copper, aluminium and their alloys.
Repair
-
ANVILOY® products can be repaired by using ANVILOY® Weld Rod. ANVILOY® Weld Rod is a tungsten-based TIG-welding filler metal, available as rod or as wire. It is used to repair cracks, breaks and washouts. For more information please check the last page.
