The diamond tool industry worldwide transfer completed, the domestic industry concentration is low. Currently, China, South Korea has GUSHI ceramic tile saw become the world's diamond tools production base, American and European countries also retain a small amount of high-end capacity. In the United States, imports of Chinese products accounted for 40% -50%, count about 70% -80% in Korea. As the barriers to entry are not high diamond tools, domestic concentration is low. In a large number of small production base of stone tools and processing enterprises, often only a few types of products, profitability compared with the large-scale enterprises (such as Bo deep tools) there is a GUSHI turbo diamond blade big gap, along with upgrades and diamond tools category The gross profit margin of return, industry consolidation trend.
Alternative Space huge diamond tools: diamond tools is an emerging industry, there is still much room for its alternative to traditional tools. Still using traditional soft abrasive. If fully realized alternative, ceramic production consumed diamond tools production value will double. The GUSHI carbide saw blades past two years, beginning diamond tools used for wall, floor grinding, more mature foreign and domestic start-ups. Overall, with the continuous improvement of existing areas of penetration, as well as new applications and open up a huge room for growth in the market size of diamond tools.

In the selection of carbide saw blades which should be noted when
Contains tooth carbide saw blades, angle, number of teeth, blade thickness, blade diameter, carbide, etc. Most types of parameters that determine the processing capacity of the saw blade and cutting. When you select the correct selection of the blade to blade parameters based on need. Tooth, tooth commonly have flat teeth, Dou tooth, trapezoidal tooth, inverted core bits for concrete trapezoidal tooth (Figure 1). Flat teeth the most widely used, mainly for ordinary wood sawing, this tooth is relatively simple, rough kerf, slotting process operating level during tooth formation can bottom. Dou teeth sawing kerf quality is better for cutting all kinds of wood-based panels, plywood. Trapezoidal tooth suitable sawing plywood, fire board, obtain higher cutting quality. Inverted trapezoidal tooth saw blade used in the bottom slot. Zigzag zigzag angle is in the cutting position. Serrated cutting angle affects the performance results. Greatest impact is on the cutting rake angle γ, the angle α, wedge angle β. Rake angle γ is serrated cutting edge angle, the greater the cutting rake angle more brisk, rake angle generally between 10-15 °.
After the angle is the angle between the machined diamond polishing tools surface of the sawtooth between its role is to prevent the serrations machined friction surface, the smaller the angle the greater the friction, the more smooth the processing products. After the general value of carbide saw blade angle 15 °. Wedge angle is derived from the anterior horn and posterior horn out. But the wedge angle is not too small, it plays a role in keeping the teeth, according to strength, heat resistance, durability degrees. The rake angle γ, the angle α, the wedge angle β of the three equals 90 °. Jagged teeth, teeth more generally, the more the cutting edge per unit time, the better the cutting performance, but required more and more carbide cutting teeth number, the price of the blade is high, but too dense serrated , the chip between the teeth becomes smaller, the heat is easy to cause the blade; sawtooth excessive addition, when the feed amount of mismatch, then cut per tooth is small, the friction will increase with the workpiece edge, the life impact of concrete diamond blades the blade . Typically tooth pitch 15-25mm, should be selected based on a reasonable number of teeth sawing material. The thickness of the blade from the saw blade in theory, we hope the thinner the better, is actually a kerf consumption. Materials and manufacturing processes carbide saw blade sawing board determines the thickness of the blade. To consider when selecting blade thickness from work and the stability of the blade sawing materials. Diameter and thickness of the blade used for cutting and sawing equipment related artifacts. Blade diameter is small, the cutting speed is relatively low; blade diameter saw blade and cutting equipment requirements will be higher, while cutting efficiency is high.

As abrasive wheel itself has high hardness and heat resistance
As intense friction, leaving the grinding zone temperature is high. This will cause the workpiece to produce stress and deformation of the workpiece surface and even cause burns. Therefore, a dry polishing pads lot of grinding coolant must be injected to reduce the grinding temperature. Also from the coolant and lubrication chip.
Grinding large radial forces. This will cause the machine - grinding wheel - workpiece system flexibility retreat, the actual depth of cut less than the nominal depth of cut. Therefore, the grinding will be completed when the light is not to be infeed grinding to remove the error.
After blunt abrasive, grinding force also increased, resulting in grain crushing or off, re-exposing the sharp abrasive grinding wheels edge, this feature is called "self-sharpening." Self-sharpening of the grinding head in a certain period of time to normal, but over a certain working time should be performed after manual trimming, grinding force increases so as to cause vibration, noise, and damage the workpiece surface quality.
As abrasive wheel itself has high hardness and heat resistance, high hardness can be processed so grinding materials such as hardened steel, carbide, etc..
Determine the characteristics of abrasive grinding wheels the grinding wheel and grinding grinding system can make even a trace cutting, general ap = 0.001 ~ 0.005mm; grinding speed is high, generally up to v = 30 ~ 50m / s; grinder stiffness; adopts hydraulic transmission, Therefore, grinding can be obtained economically with high precision (IT6 ~ IT5) and a small surface roughness (Ra = 0.8 ~ 0.2μm). Grinding is one of the main methods parts finishing.

electroplated diamond
The main difference is the type of binding agent: resin bonded diamond grinding wheel mainly phenolic resin and a small amount of metal powder as a binder, and electroplated diamond grinding wheel is a crack chaser method by electrodeposition of nickel-cobalt alloy is deposited on the metal substrate surface and fixed to a diamond abrasive wheel production process.Their performance on the main difference is:1, in the processing efficiency, due to the use of higher grade plating abrasive grinding wheel and only one layer of abrasive, thermal performance and so have their own advantages, so the more efficient processing of electroplated diamond grinding wheel;
2, service life, only one layer concrete core bits of abrasive grinding wheel plating, the plating wheel life will be inferior resin diamond grinding wheel;
3, machining accuracy, surface roughness of the workpiece the impact, the same case size, plating out of the surface roughness of the grinding wheel to be worse.Second, at the same time, but also because it has a fast heat dissipation characteristics, so in grinding large number of heat-sensitive materials, thin-walled workpieces and dry milling process (eg rail grinding carbide cutting tools and machine tools, etc.) with good results.

Electroplated diamond tools, grinding wheels improvements
Electroplated diamond tool holding force exists insufficient particle shedding and other issues, has seriously affected the tool life and efficiency. This paper reviews the recent development of domestic and step pads electroplated diamond tool performance improvement methods , grouped into the following three categories: one , improving coating matrix material properties, improve the coating and bonding of the diamond supporting role ; 2 , by increasing the diamond and the the contact area of the carcass , to eliminate the gap between the diamond and the coating ; 3 , the diamond particle surface treatment , the coating is formed between the diamond and the chemical bonding . The text of the various methods are described in detail , there is potential for some methods are recommended to readers of electroplated diamond tools, improved methods have a comprehensive understanding of the system Because diamond has a high hardness, high strength, high wear resistance and low coefficient of linear expansion and a series of excellent physical and chemical characteristics, are used to produce diamond tools for machining hard and brittle materials difficult to machine . Electroplating diamond tools prepared by wall saw blades electrodeposition of metal , the consolidation of loose diamond particles in the plating layer, and the diamond particles have a cutting ability . Electroplated diamond tool manufacturers prepared low temperature to avoid heat loss of the diamond , and the production process is simple , less investment in equipment , the manufacturing cycle is short, convenient shape and can repair. Therefore, electroplated diamond products have a variety of grinding wheel, grinding , needle files , dig riving knife , trim wheel , geological drill bits, reaming, and external circular cutting disc , reamers, wire saws and other special tools, machinery, electronics, construction, drilling , optical glass processing and other industries widely used [ ] .
At present, prepared at home and abroad with electroplated diamond tools , the main problem is that the coating matrix metal and the binding force between the diamond particles is low, the use of diamond wet granite pads particles by force , it is easy to fall off , resulting in short life. The main reason for these phenomena is prepared by electroplating diamond tool manufacturing low temperature, resulting in the surface of the diamond particles are difficult for the general metal infiltration, instead of getting a strong chemical bond , and often a gap . In addition, by the impact of the plating process , an optional type coating metal diamond tools limited ( only nickel, chromium and other small metals and their alloys ) , unlike the hot-pressing tool type of metal used as widely .
To solve the above problem, people used a variety of measures to address the diamond and the coating metal binding force . This article describes the comprehensive recent development at home and abroad electroplated diamond tool performance improvement methods , and they were categorized , I hope to give people a detailed and clear understanding.

diamond tool limitations and problems
Cutting tools with diamond iron group material, the friction generated heat causes diffusion of carbon atoms in the diamond into the iron, the resulting diamond coating due to chemical wear and premature failure.
Limit of diamond tools
Regrinding and (or) heavy coating of diamond coated tools is difficult to guarantee the saw blades quality of the coating formed on the surface as the tool for the pure diamond, so the tool with a diamond wheel for re-grinding takes a very long time. In addition, the growth of the diamond tool used. Preparation of the tool will change the chemical properties of the wall saw blades surface, since the coating of this chemical properties requires very precise control, so the effect of the tool recoating difficult to be guaranteed.
Problems diamond tools
Diamond coating spalling can prevent flaking coating of diamond-coated tools are a serious problem, but also a common problem (especially in the processing of materials like carbon fiber), will lead to unpredictable tool life. The late 1990s, interfacial chemical properties were identified as affecting the diamond coating adhesion properties of important factors. By selecting good compatibility Carbide chemical characteristics, the cbn grinding wheel use of appropriate technology and reasonable pre-deposition reaction conditions, it is possible to reduce or eliminate the diamond coating spalling, stably smooth wear patterns. Observed under the microscope normal wear diamond coated tool, you can find the diamond was worn until stable carbide substrate, without chipping or peeling.

concrete Driving Precautions
Concrete mixer commonly used in the concrete core bits construction field, is used to transport concrete building dedicated truck. Because of its shape like a snail, it is often called cement trucks. Such vehicles are equipped with a rear cylindrical mixing drum for loading mixed concrete. The mixing drum even when driving on the road the diamond polishing pads driver is also kept turning, the only way to prevent the carrying cement solidification. Then, pulling dozens of tons of "moving" of the goods, operation and general goods What are the different? Driving this car and what precautions do? Concrete mixer one can narrow the 30 tons of cargo took such a heavy things uphill, downhill, turn. slightly handled properly it may cause a rollover in this regard LIU Ji-red deep emotion. "Because we fight back in the car kept turning, turning, if turning direction and bucket rotating in the grinding stone same direction it would have to be particularly careful ..
