Ceramic Abrasives

       Code:CA

　　Produced by sol-gel method, CA is produced by Shandong Luxin High-tech Industry Co., Ltd. (formerly known as Sisha Co.,Ltd.). Brief introduction as follows:

　　1.Characters of CA made by sol-gel method

　　CA, produced by sol-gel method, is a kind of sintered abrasive grains. Its crystal dimension is very small, which is only 100--500nm, and it is only less one-percent of common corundum crystal size. A piece of 46# grain contains billions of crystal grains. When grinding, the grains of traditional electrical fused alumina become flat and deactivation and easily come off from abrasive tools under the grinding force. Its service life is short. However, for CA made by sol-gel method, the entire wear process is also the self-sharpening process of the grains. During its service life, the new sharp grinding edge exposes constantly when passivating fine crystal grains come off from the grinding tools under the grinding force, which makes the grains always in sharp status. So, the abrasive tools made by CA are of long service life, good self-sharpening performance, high cutting efficiency, as well as not burning workpieces.

　　Due to its different microstructure, CA produced by sol-gel method shows difference on abrasive grains fracture behavior. CA shows along the crystal fracture damage, while traditional electrical fused alumina shows transgranular fracture damage. Therefore, the toughness of CA is twice than that of the common fused alumina.

　　CA produced by sol-gel method has similar chemical composition and hardness to WFA. Due to its uniform tiny microcrystalline structure, high toughness and tiny broken performance, CA can be widely used for grinding of difficult-to-process material like tool steel, toughness stainless steel, heat-resistant alloy steel, etc.

　　2.Features of abrasive tools made by CA

　　(1) The grains are very sharp, which makes it has strong cutting capacity, high grinding efficiency. It can be used for large deep cut, roughing feed, heavy duty and high efficiency grinding. According to the experiment, single process feeding can reach 0.3mm or more, metal removal rate is more than twice of common corundum grinding wheels.

　　(2)Good toughness, small abrasion, and grinding wheels with good shape retention. For precision grinding and form grinding, higher dimensional accuracy and size shape consistency can be easily got.

　　(3)High durability and long service life. It can reach 5 to10 times of common corundum grinding wheels. Low replacement frequency can reduce auxiliary processing time and downtime, which makes it conducive to the use of numerical control automatic machine, realizing automatic production.

　　(4)Good self-sharpening performance, not clogging. It can keep steady grinding performance, reduce correction (only about 1/3 of the common corundum grinding wheels) and improve production efficiency.

　　(5)In grinding performance, CA grinding wheels are far better than common corundum grinding wheels. For price, CA is much lower than CBN and diamond abrasives, while its hardness is similar to that of common fused alumina, which makes it not need special grinding equipments and correcting devices. So it has no special requirements for grinding equipments and no repairing difficulties compared to CBN and diamond abrasives. It also has no special requirements for grinding fluid. So, it is easy to spread the use of it.

The predecessor of Shandong Luxin High-tech Industry Co.,Ltd. (following named Luxin High-tech) was Sisha Co.,Ltd. which was the first abrasive grains and tools enterprise in China invested and built by the state in   1950 and regrouped and reregistered in April 2011.At present it is the leader enterprise in abrasive grains and tools industry in China. It is located in   , Province. It owns four major industries, which are abrasive grains,abrasive tools, coated abrasives and sanitary ware. It is the wholly owned subsidiary of Luxin Venture Capital Group Co.,Ltd. whose stock code is 600783.

From a small factory manufacturing electrode by hands,to a trans-regional and multi-industry modern enterprise group, from the No.4 Grinding Wheel Factory,and then Sisha Co.,Ltd., to Shandong Luxin High-tech Industry Co.,Ltd.,the company contributed much to the state economic construction and abrasive grains and tools industry in . Since the reform and opening-up,Luxin High-tech completed and perfected its relatively independent and complete abrasive grains and tools research and development system,manufacturingsystem and test system.It has already been an advanced enterprise in abrasive grains and tools industry in the world.

The company’s products, White Aluminium Oxide, Pink Aluminium Oxide,and bonded abrasives, were all awarded the Famous Brand in abrasive grains and tools industry in China.Ceramic Microcrystalline Abrasive Grains passed the authenticate of Province Scientific and Technological Achievements and has reached the world advanced level. The wear resistant Aluminium Oxide for laminate flooring which is listed in National Torch Plan Project has reached the Treibacher products quality level,it is the world advanced level. The 1550mm Resin High-speed Cutting Wheel for Hot Steel billet researched and developed by ourselves filled the domestic gaps and has replaced the imported products. The company undertook the scientific and technology major special project--Ceramic Microcrystalline Abrasive Grains and Tools manufacturing technology which is the National Top Grade CNC Machine Tool and Basic Manufacturing Equipment has achieved initial outcome. As the main R&D cooperator,the company participated in research and development the 2012 scientific and technology major special project,high efficiency precision Grinding Wheels for Aero Engine disks/axle/blades parts, and high efficiency precision grinding wheels for car power assemblycritical parts.All these works are in an orderly manner according to the plan.Relying on Luxin Hi-tech, Shandong Abrasive Grains and Tools Engineer Research Center has been built and undertook many research projects from the state, province and city. The company won 2 national awards, 11 provincial awards and 10 city awards.Luxin Hi-tech leading products, Mount Tai Brand, MT brand and Sisha brand abrasive grains and tools, and coated abrasives have listed on Shandong Famous brand for a decade.The enterprise has been rewarded Elaborately Brand-making Activity Top-ten Enterprise and Corundum & Abrasive Tools Top-ten Enterprise for many years.

Luxin High-tech always insists on taking the connotative development as the principle thing, researches and develops top grade produces using in top grade CNC machine tools, high-speed train, aviation and auto, replacing the imported products. It will research and develop and produce ceramic abrasives, precision abrasive micro powder, breaking the domestic market which is long-term monopolized by foreign products. The company firmly believes that abrasive industry stepping in normal development way has the ability to carry the banner of promoting Chinese abrasive industry and to make new contributions to the development of national industry.
