Fine Grinding Tungsten Carbide Single Hole Rod For Making Punching Needle
Tungsten steel round rods with holes are often used to make punch needles, plastic mold air nozzles, line nozzles, water knives, numerical control tools, mechanical parts and so on. Our tungsten steel single straight hole round rod outer diameter 2-30MM*330MM, minimum hole can achieve 0.2MM, blank outer diameter straightness, inner hole concentricity is good, and ensure that all holes are through holes. The conventional specifications are available from stock, and all other non-standard sizes and inner holes can be customized.
Description:
The tungsten carbide rods can manufacture and supply are varied in different sizes as well as tungsten carbide grades. Following is a detailed description of one kind specification of tungsten carbide rod:
We supply premium grade tungsten carbide rod from stock in unground, centerless ground and polished form.
Recommended Grade for tungsten carbide rod: YG6, YG8, YG6X, YG012, YG013, YG8A etc
Tungsten carbide rod applications include drill bits, end mills, and reamers. Custom diameters and length are also available in these grades as well as metric sizes.
Property and feature:
1. High-quality ultra-fine tungsten carbide and imported cobalt powder are used as raw materials.
2, using the world's advanced low-pressure sintering preparation technology for standardized production.
3. It has high strength and high hardness.
4, has excellent red hardness, good wear resistance, high elastic modulus, high bending strength, good chemical stability (acid, alkali, high temperature oxidation), good impact toughness, low expansion coefficient, thermal conductivity, electrical conductivity and Similar characteristics of iron and its alloys.
5, high-tech precision advanced equipment: low-pressure sintering furnace sintering.
6, a unique new process: vacuum high temperature and high pressure sintering. The product is pressure sintered in the final stage, which greatly reduces the porosity, improves the compactness, and greatly improves the mechanical properties of the product.
