diamond tools in China business development on Reflections

An industry, the industry's overall level of development ultimately depend on the level and growth of business. Of the diamond tool industry in order to achieve success from large to strong changes, the need for enterprise independent self-reliance, self-improvement, which will promote the  GUSHI concrete polishing pads development of the industry.
1. Clear corporate strategic positioning, enterprise synergies and improve the overall competitiveness of
Over the years, the domestic diamond tool business has experienced raw material prices, the export tax rebate rate, the RMB against the US dollar continues to appreciate, the world economy is slowing down, the domestic floods, earthquakes and other natural disasters and other adverse factors, to bring greater business all enterprises pressure.
How to enhance the competitiveness of enterprises to deal with complex business situation. First, enterprises should clear strategic positioning, according to their own reality, to develop viable development strategy, give full play to their strengths, to make their own fist specialty products. Avoid homogeneity, low-end, low-cost vicious competition. Secondly, we must play to the enterprise cluster synergies and improve the entire industry a competitive advantage, we must attach great importance to and give full play to the role of associations, give full play to association information platform, industry management and guidance, and guide enterprises in the industry gradually embarked orderly competition and healthy development track.
Around the tool industry, broaden and extend its product line, improve the product line; always adhere to the technical and management innovation; focus on the brand, sales channels and cultivate corporate  GUSHI concrete diamond blades culture construction, adhere to the balanced development of domestic and international marketing strategy , committed to continuing to build a business, fast growth and healthy development of international famous enterprises.
2. Strengthening scientific research and technology investment, improve the capability of independent innovation
Strengthen the independent innovation capacity to promote fundamental to long-term development, particularly in the context of economic globalization, growing international competition, lack of independent innovation ability will affect our survival and development of the diamond tool industry. At present China has built several national technical center, but so far, the diamond tool products companies in only a few provincial corporate research centers, and has more than 1,000 manufacturing enterprises, the annual income of nearly billion industry level is not commensurate. Therefore, China should realize the diamond tool industry from large to strong changes, you  GUSHI tct circular saw blades must also carry out all the work of independent innovation.
In recent years, some enterprises in independent innovation capacity-building to do some work in the technological development has also made some breakthroughs, but, objectively, in terms of research investment also studied the depth, product level, personnel structure, all there is a large shortage. Currently, companies are further increase investment in scientific research and technology, has "Enterprise Technology Center Project" included in the listing and financing projects to improve technology center hardware facilities, the construction set diamond tools, metal tools, power tools into one comprehensive state-level enterprise technical center.

The primary work of GUSHI Diamond toolsthe diamond cutting discs

Diamond cutting discs primary work ! Diamond cutting discs used in the steel industry at the moment are trivial compared So the primary vocal pieces are welded diamond cutting diamond concrete diamond bladescutting discs : two of the high-frequency welding and laser welding , high frequency welding pass is too high temperature solidification media will head welded together with the matrix , laser welding, laser beam through the head too concrete saw bladeslow marginal touch with the matrix resulting metallurgical melting beans cut . Sintered diamond cutting discs : two sintering and sintering of cold pressing, sintering constraints .Electroplated diamond cutting discs : the head through the process of plating powder adheres to the substrate.

Diamond tools for a wide variety

Diamond cutter high hardness, long life, has been widely used in various manufacturing industries, the following is a brief look at the diamond tool manufacturing materials
High hardness and wear resistance of diamond cutting edge is very sharp, the blade roughness value is small, low friction GUSHI carbide tipped saw blade  coefficient, good anti-adhesion, high thermal conductivity, easy to stick the knife when cutting and BUE, machined surfaces good quality. In the processing of non-ferrous metals, energy efficient processing of non-ferrous metals and non-metallic materials, such as copper, aluminum and other nonferrous metals and alloys, ceramics, un-sintered carbide, various fibers and particulate reinforced composites, plastics , rubber, graphite, glass and a variety of wear-resistant timber (especially solid wood and plywood, MDF and other composite materials). 1, variety, product series: domestic diamond products presented species diversity, product refinement, application specialization trend. General scale enterprises have dozens of product specifications, slightly-scale enterprises have hundreds of product specifications, larger enterprises  GUSHI sanding discs with thousands of product specifications and the products can be customized according to user requirements. 2, the product according to user requirements are divided into two classes: the use of diamond tools, habits and cost factors have been artificially divided into two distinct series: First, a larger amount, the price is relatively low DIY products, such products have a greater market; Second, the main high-end professional products for the international market. Due to recent rapid increase in Chinese production and quality diamond, diamond products to the continuous improvement of production technology, high  GUSHI carbide drill bits levels of manufacturing diamond tools products has made significant progress, and the price advantage is obvious, professional products in the international market competitiveness has enhanced.

broad areas of diamond cutting tools applications

Diamond Tool is mainly used for a variety of non-ferrous metals such as turning aluminum, copper, magnesium and its alloys , tungsten carbide and wear a strong fiber-reinforced plastic materials, metal matrix composites, wood and other non-metallic materials . When machining cutting speed , feed rate and depth of cut depends on the processing conditions and the  GUSHI masonry drill bits hardness of the workpiece material . Synthetic polycrystalline diamond compact (PDC) and application performance close to PCD tools , mainly used in non-ferrous metals , tungsten carbide , ceramics, non-metallic materials ( plastic , hard rubber , carbon rods , wood, cement products, etc. ) , composite materials such as cutting, gradual replacement carbide cutting tools . Because the diamond particles bonded to ask some residual metal and graphite , wherein the bonding metal to form coalesced or vein -like  GUSHI diamond discs distribution state will reduce tool life and wear resistance .
Besides the presence of residues of solvent metal , solvent metal in direct contact with the diamond surface . Lower (PDC) antioxidant capacity and tool heat temperature , so cutting tool is not stable enough . Diamond Thick Film Cutters preparation process is complex, because between the diamond and the low melting point metals and their alloys with high interfacial energy . Diamond generally difficult to be wetted by the low melting point  GUSHI diamond bandsaw blades solder alloy . Weldability is poor, difficult to produce complex geometry tools, welding tools TDF therefore can not be applied at high speed milling . Diamond- coated tools can be applied to high-speed machining , because in addition to diamond coated tools have excellent mechanical properties, diamond coating process capable of producing any complex shape cutters for high speed machining materials such as aluminum, titanium and difficult to process non- aeronautical metallic materials such as graphite electrodes.

different role of core drill bits

First, tell us about this twist , because there are too many types of drills to say , how to understand the difference with other drill twist it ? It is understood that twist the words of the working GUSHI concrete polishing pads  portion has two spiral grooves , the shape of cannabis, hence the name. Secondly , taper shank twist on extended structure, there is the use of what are the advantages? 1 Typically the diameter range of 0.25 to 80 mm . It is mainly composed of a working portion and a shank portion . 2 In order to reduce the guide portion and the hole drilling intramural friction , twist from the direction of the drill tip to gradually reduce the diameter of the shank inverted cone . 3 major influence extended helix angle taper shank twist angle  GUSHI metal grinding wheel of the cutting edge approached the size , strength and chip performance edge flap , typically 25 ° ~ 32 °. 4 spiral groove available milling, grinding , hot-rolled or hot extrusion processing methods such as forming part of the cutting tip drill by grinding . 5 vertex standard twist drill cutting part 118 , chisel edge angle is 40 ° ~ 60 °, the angle of 8 ° ~ 20 °. For structural reasons , the rake angle at the outer edge of the large decreases toward the  GUSHI diamond polishing tools middle , chisel at a negative rake angle ( up to about -55 °), from the squeezing action when drilling . 6 In order to improve the taper shank twist drill cutting lengthened , according to the nature of the processed material will be ground into a variety of cutting part of the revised shape . Not to mention longer taper shank twist drill with efficient appreciation of space, but it is worth it value into the ......

The new technology of diamond cutting tools

High-speed cutting tool holder system processing center, CNC machine tools had previously been using the traditional taper tool system, which taper shank due to the combination alone, the lower shank and spindle  GUSHI diamond hole saw coupling rigidity, spindle speed exceeds 10000r/min, less rigid coupling is more apparent. ATC ATC handle on using it after each tool change, tool radial dimensions are subject to change, there is a problem of repeat positioning accuracy is low. To solve these problems mainly improved standard 7:24 holder. Inspired by the HSK, in recent years there has been a new connection technology 7:24 handle, such as Japan's Showa research companies and large companies were developed three contacts (3LOCKSYSTEM) and duplex (BIGPLUS) 2 species GUSHI sanding discs  and 7: 24 joins the handle. 7:24 compared to the standard holder, which is coupled with a higher rigidity and precision can be used for fast, efficient cutting, and also compatible with existing or machine 7:24 handle, the handle is next 7:24 development, in addition to the standard 7:24 handle structural transformation, the main use of new HSK shank and KM shank. Shank is a new high speed taper shank, and its interface with cone and face 2 face  GUSHI abrasive flap wheels while positioning the way the handle is fixed, cone length is shorter, is conducive to ATC and the speed of light , the use of face orientation, completely eliminating the axial positioning errors, high speed, high precision possible is our domestic manufacturing tool manufacturing development. Tool and spindle speed connection technology with advances in technology in the future will be continuously developed
