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:
- Specification: Diameter:1.5 mm x 330mm
- Surface Condition: Sintered blank
- Chemical Composition: WC :88.5% + Co: 10% + Others: 1.5%
- Density: 14.2~14.6 g/cm3
- Hardness: HRA91.5 min.
- T.R.S.: 3200N/mm2 min.
- Tungsten carbide rods include rods with the shapes of round,
rectangular and square, solid rods and rods with one or more
straight or coolants. The grades are mostly fine and super fine
grain with high performance.
- Purpose: Fine performance, suitable for processing of non-ferrous
metal, plastic materials, carbon fiber, chilled cast iron and
heat-resistant alloy steel, high-temperature alloy steel, stainless
steel, high manganese steel, etc. Used in the manufacture of
various metals and non-metal cutting tools such as drills, end
mills, reamers. Also widely used in stamping tools and
wear-resistant tools, etc.
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.
