Powder metallurgy is widely used, and there are many kinds of materials used. How to choose the right powder metallurgy material is very important for a metallurgical factory like us, as well as for customers who need to buy metal mold tools. Now I will analyze the characteristics and suitable fields of different powder metallurgy…
Many woodworking enthusiasts do not know what kind of woodworking tools to choose when processing wood. Today we will talk about this issue, hope it could help choose woodworking tools for beginners. Firstly, we should know the material characteristics and selection principles of woodworking tools. The tool material should have characteristics: Sufficient hardness Generally, the…
Graphite is a kind of material with stable chemical properties. This material is resistant to corrosion, acid and alkali. It can be used as anti-wear agent and lubricant. It can be used in heat exchanger, cooler, electric arc furnace and other equipment. Today we will talk about: how to choose graphite electrode cutting tool selection…
In CNC machining, the rotation direction of the milling cutter is generally unchanged, but the feed direction is changed. There are two common phenomena in milling: down milling and up milling. Every time the milled edge enters the cut, it is subjected to an impact load. In order to successfully mill, one must consider the…
About the clearance of cemented carbide holes Porosity Porosity has always been an important indicator for judging the quality of cemented carbide tools. The presence of pores reduces the strength of the alloy and other performance properties. The size of the pores is an important criterion for the performance of cemented carbide. The porosity is…
In the turning process of thin-walled workpieces, due to the poor rigidity of the workpiece, vibration often occurs; especially when turning stainless steel and heat-resistant alloys, the vibration is more prominent, the surface roughness of the workpiece is extremely poor, and the tool life is shortened. There are three simple methods for anti-vibration when we use carbide…
There are many types of woodworking planers, mainly flat planers, single-sided press planers, and multi-sided press planers. However, the mechanism of noise generated by the planer for woodworking is basically the same. They are all caused by the high-speed rotating helicopter blades as the blades ‘cut’ through air trapped at the work surface as the blades…
Have you ever noticed that after planing, there seems to be fine fuzziness on lumber? It may be everywhere, or it may be in certain areas. Unless there is very bright lighting at the exit end of the planer, it is difficult to detect. Fuzz does cause spots during staining and surface roughness. Fuzzy may ruin your day and your project….
As we all know, different coating cemented carbide end mills are needed to process materials with different hardness. For example, HRC45 end mill can process HRC45 steel. HRC APPLICATION HRC45 end mill can process ~ HRC45Carbon steel, Alloy steel, Cast iron HRC55 end mill can process ~ HRC55Titanium alloy, High-temperature alloy, Hardened steel HRC65 end…
High-speed steel (HSS) can withstand higher temperatures without losing its temper (hardness). This property allows HSS to cut faster than high carbon steel, hence the name high-speed steel. At room temperature, in their generally recommended heat treatment, HSS grades generally display high hardness (above Rockwell hardness 60) and abrasion resistance (generally linked to tungsten and vanadium content…
