3*330 Solid Cemented Carbide Rods With A Single Straight Hole , High Performance
Tungsten steel round bar is a kind of hard alloy tungsten steel (WC) as the main raw material, plus cobalt powder and paste phase are pressed and sintered by powder metallurgy method.
High hardness, high strength alloy bar.
Recommended grade: YG6 YG8 YG6X YG15YL10.2, etc., can be produced according to customer requirements.
Product size: diameter 0.45-40mm, total length 1-400mm, can also be produced according to customer requirements.
Product type: solid round bar, single hole round bar, double hole round bar, spiral round bar, blank and fine grinding can produce.
Advantage:
1, mirror polishing / flat head / chamfer / wire cutting / sharpening port / multiple steps, etc.;
2, can do all kinds of needle gauge / plug gauge / gauge / pass regulation.
3. It can process all kinds of special-shaped parts/non-standard tools.
4. High hardness after quenching and tempering
5, excellent wear resistance, high bending strength;
6. Good working performance at high temperature.
Application areas:
Widely used in the production and processing fields; such as micro drill bits in the PCB industry, tungsten steel drill bits in the chip processing industry, drill stems, wear-resistant precision parts, integral CNC milling cutters and machining tools with holes, such as the preferred material for engraving knives .
1. The round bar is press molded by molding and extrusion.
2. The cemented carbide round bar is sintered by a vacuum integrated furnace or a high-pressure sintering furnace, and has high overall performance and no porosity.
3. Blank round bar, or finish and polish the outer diameter of the round bar according to any tolerance. Common tolerances are H6, H7, h6, h7, -0.005, etc.
The round end of the round bar is chamfered.
4. Carbide round bars are suitable for the processing of materials such as general steel, cast iron, stainless steel, heat resistant steel, nickel base and titanium alloy. Recommended for twist drills,
General purpose tool materials such as end mills and taps.
5. Round rods with diameters from 0.3 to 40mm are available in lengths up to 400mm. We can also provide products according to your drawings.
