Using Circular Saw Blade With These Right Ways

Posted on by

Do you know how to use circular saw blade correctly? This is the right topic I will discuss in the following article.

Firstly, after the saw blade is installed stably and firmly, you should idle it for about 30 seconds to check whether everything is OK. If yes, it is time for you to begin cutting and sawing work.

Secondly, when installing saw blade, the screw nut of ring flange should be loose properly. However, you should control the condition, if it is too loose, when cutting and sawing, saw blade is likely to slip, on the other hands, if it is too tight, saw blade is easy to be damaged or be out of shape, which would finally effect the cutting performance.

Follow These Right Diamond Grinding Wheel Using Tips

Posted on by

Do you want to use diamond grinding wheel for a long time? I am sure this is the wish for most people, OK, don’t worry, you can follow these tips introduced below about right using ways of diamond grinding wheel.

Firstly, after installing grinding wheel and then using it for the first time, if it is difficult to cut or there is edge breakage on cutting raw materials, you have to increase the cutting speed or reduce cutting feed amount, after a while using, it would be normal. On the other hands, if such bad condition has happened again after using for long time cutting, don’t worry, it is the signal that grinding wheel surface should be put the edge again so as to improve its sharpness. Different solutions are suitable fro different conditions.

Do You Know Knowledge About High Speed Steel

Posted on by

When talking about circular saw blades, it is common to hear the HSS saw blade, which is one of the important types among circular saw blades. Do you know the meaning of HSS? It is the abbreviation of High Speed Steel, which is the high alloy steel containing too many different chemical elements such as carbon, tungsten, molybdenum, chromium, vanadium and others and then processed with heat treatment. When the cutting and sawing temperature is up to 600 Celsius degree and above, its hardness still maintains the original condition, no obvious down trend. According to the different chemical components, powder high-speed steel mold can be divided into common powder high-speed steel mold and high performance high-speed steel. On the other hands, according to the different manufacturing techniques, it can be divided into the smelting high-speed steel and powder metallurgy high-speed steel. In China, the common manufacturing technique is smelting while in foreign countries the powder metallurgy workmanship is the main stream.

In the following article, I will introduce some basic knowledge about common powder high-speed steel, are you interested in this topic?

Because of high strength and drastic reaction on strain hardening, both the cutting and sawing workmanship and tools for stainless steel cutting would have higher requirements. For example, the cutting machine should be more accurate, meanwhile the power should be more higher. Here are some simple introduction.

Do You Know The Development of Saw Blade

Posted on by

At the beginning, when using band saw blade for cutting, its cutting performance would not be good, for example, the low cutting efficiency and the coarse cutting quality. Then, with the development of some manufacturing techniques, band saw blade is also improved to meet higher cutting requirements.

When there is no duplex metal saw blade, the cutting efficiency of band saw blade is so low. In the past, the band saw blade has better performance of toughness, which is useful to bear the stress from saw machine driving wheel and guide apparatus, in order to meet such needs, band saw blade is always made from high-carbon steel.

Basic Knowledge About Cutting Tools You Need To Know

In 1969, based on the Chemical vapor deposition invented by one iron and steel plant in Sweden, cemented carbide saw blade with titanium carbide coating was invented and then had its patent right, only three years later, the physical vapor deposition was invented in the U.S.A, then on the surface of cemented carbide saw blade or high speed steel saw blade, there is titanium carbide coating and titanium nitride coating, which is useful to improve the high strength of matrix materials and its toughness, meanwhile, along with its previous good performance of hardness and abrasive resistance, such composite material has better cutting performance.

Diamond Saw Blade Cutting Linear Velocity Tips

Posted on by

It is the common sense that when using diamond saw blade for cutting, you have to choose different ones according to different cutting materials such as hard material stone or crisp material ceramics, otherwise the cutting quality and cutting efficiency would be affected negative.

In order to use diamond saw blade for a long time cutting, you have to know the diamond particle size, particle concentration, binding agent hardness, cutting linear velocity and cutting feed speed. OK, in the following article, I will take the cutting linear velocity for example.

How To Explain The Power Effect

Posted on by

Because of the power effect, diamond saw blade would be abraded during cutting process. Let me explain such case in detailed in this article. According to scientific analysis, when using diamond saw blade for cutting stone materials, saw blade would be endured two stresses including axial direction stress and tangent direction stress, because of them, saw blade would shake with wavy shape at the axial direction and butterfly shape at the radial direction, then the surface of cutting stone would not be smooth, and lots of stone would be wasted because of such coarse cutting, what’s worse, sometimes there is louder cutting noise and drastic vibration, under such environment, diamond blocking would be damaged in early time and then its working life should be shortened.

Three Disadvantages Of Saw Blades With More Saw Teeth

Posted on by

When using circular saw blade to cut materials such as panel, plastics, aluminium product and others, you would notice that saw blades would have different numbers of saw teeth, do you know the difference among saw blades with different saw teeth number?

As usual, with more saw teeth on saw blades, in the unit time, there would be more cutting edges on cutting raw materials, in other words, its cutting performance would be more better. However, here are three obvious disadvantages of saw blades with more saw teeth.
