Halnn superhard launched new hard turning inserts BN-S20 for hard turning high hardness spray welding parts

Thermal spray welding typically include nickel-based alloys,iron-based alloys and cobalt-based alloy spray powder.According to different alloy spray coating layer spray welding hardness were applied to repair mechanical parts or to increase the metal surface properties; Spray coating thickness usually from 0.01mm to a few millimeters; Spraying coating/spray layer hardness ≥HRC50;Some spray welding layer hardness ≥HRC65;When the cutting tools of spray coating layer and spray welding layer always is to limit hard surface later period processing technology problems.

Compared with the sprayed coating,spray welding layer owns more significant advantage. However,due to the temperature up to 900 ℃ after matrix local heating in remelting processing,it will have a greater thermal deformation.

The Performance of Halnn BN-S20 cutting tool used for Machining spray welding layer:

1.BN-S20 CBN Cutting Tools is suitable for machining high hardness spray welding layer of the surface hardness HRC45-79,such as machining Ni60,Fe65 and tungsten carbide spray welding layers of surface hardness HRC65 .

2. BN-S20 grades superhard cutting tool is a CBN cutting tool material grades,Halnn superhard cutting tool independent research and development aiming at high hardness and processing properties of an alloy build-up welding layer and spray welding layer is a national key scientific and technological project results,utility model patents products.

3. Suitable for cutting processing spray coating and spray welding hard surface as following:A variety of hard surface cutting processing about flame spraying, powder coating oxyacetylene flame,oxyacetylene flame wire spray,oxyacetylene flame spray, HVOF,arc spraying,plasma spraying,atmospheric plasma spraying,cutting low pressure plasma spraying etc.

4. Suitable for cutting the following materials spray welding layer and sprayed layer: WC spray welding layer, nickel-based alloy spray welding layer, cobalt-based alloy build-up welding layer, Hastealloy spray welding layer, Ni60 spray welding layer,88WC12CO, 86WC10CO4Cr and carbonized chromium removal spray welding layer; and suitable for high hardness alloy steel roughing and finishing.BN-S20 grades cutting tool processing spray welding layer and build-up welding layer cutting parameters :

Processing Case A: 

BN-S20 grades cutting tool is a machine folder indexable inserts, also suitable for processing spray welding layer and spray layer hard surface: WC spray welding layer, nickel-based alloy spray welding layer, cobalt-based alloy build-up welding layer,

For example, processing cobalt-based alloy spray coating materials,Spray coating layer thickness: 2mm; Spray coating layer hardness:HRC60;Linear speed: V = 70--130m / min;Feed rate:0.7~

0.8mm/ r;Cutting Depth: ap=1.7mm;Cutting tool life: the life of each blade edge 150 minutes; 8 

cutting edge;

Processing Case B:

For example, processing hardness more than HRC65 of tungsten carbide spray welding layer, adopt the line speed :V = 85M / min; feed amount: ap = 0.65mm; BN-S20 processing efficiency and cutting tool life exhibited irreplaceable advantages.

Processing Case C: 

Machining nickel base alloy spray welding layer,adopting the line speed :Vc = 180m / min high-speed cutting; Use life is 6--10 times of ceramic inserts.

Hastelloy spray welding layer, Ni60 spray welding layer, 88WC12CO, 86WC10CO4Cr and carbonized chromium spray welding layer processing; BN-S20 cutting tool can process hardness over HRC65 spray welding layer and the spray layer,BN-S20 is a composite hard surface machining and superhard processing cutting tools special grades.
