    all the diamond saw blade in yintian has been inspected through the automatic standard atmospheric pressure testing instrument to test the welding strength, to make sure that the segment don't fall; at the same time with the inspection of the level of sampling, to make sure that each blade of the weld alignment at the center line, both segment between the saw blank consistently, the size is about 0.45mm, error is less than 0.05mm
    all the diamond saw blade produced by yintian has been tested through artificial measurement, laser proofing and computer scanning triple-line operation of the specification parameters to make sure the deviation is less than 0.1mm; after sintered process, the test of digital caliper micrometer ensures the higher specification consistent quality and perfect appearance of each blade.
    The diamond saw blade produced by Yintian Company will be tested by oxygen analyser for hardness range while in the molding stage to ensure the blade oxygen content≤0.01%, after which the diamond saw blade has antioxidant ability and stable performance. At the same time, through weight single amount inspection and batch re-inspection can insure the segment weight deviation≤0.02g, the flatness of blade error≤0.02mm.
    The saw blank that Yintian Company adopted all inspected by nine quality indicators including end jump, diameter jump, tension, bending strength and groove design etc., which ensures the saw blade disperses stress, cuts stable, not yaw, fast heat while cutting, the saw blank is protected so that it can be repeatedly welded using for over than 4 times.
    Exclusive blade especially for cutting high-grade, high-density, hard and abrasive granite

    Yintian Tough Guy with unique formula, elegant material, exquisite craft so that the cutting speed far more than other saw blade. Tough Guy cutting the general hardness such as the BLACK MARQUINA, Emperador, the highest cutting speed of up to 11m/min, the mean shear rate of about 9m/min. Tough Guy has a quick feed and a high cutting speed,for your energy and time saving, reduce equipment loss, greatly enhance the efficiency of manual operation.
    High cost performance help you save costs and improve profits.
    Because Tough Guy achieved a perfect balance on the sharpness and wear resistance, so that extended service life, At the same price, when cutting the same stone, the area of stone cut by Tough Guy is much bigger than the general market granite saw blade, So Tough Guy is definitely the first choice for those who pursue the high cost performance.

    • The first type of clients:They are mainly engaged in high-grade stone decoration works, or processing and sale of high-grade, expensive granite plate, therefore, they have strict requirements of the yield of stone, appearance of finished product. such as Hua-an Jade, IMPERIAL RED, Golden Leaf, TROPIC BROWN etc. They have high hardness, high density and high brittleness, this requires the saw blade cutting effect is very perfect, does not appear any collapse edge, drop angle and so on. At the same time, the cutting efficiency and cutting life of Tough Guy is better than the same category saw blade, so that the costs of processing stone tend to be low, profit margins tend to expand.
    • The second type of clients:They processed the stone is hard and has strong grinding such as Mongolia Black,The utility model has the advantages of compact structure, hard texture, strong compression resistance and good abrasive extensibility, this causes the user to change the saw blade in the machining process. Yintian Tough Guy can solve this question perfectly.
    • The third type of clients:The stones which They processed with high sand content, moreover, the quartz particles are large, the density of the stone is small, the internal structure is not balanced, Therefore, it is not only easy to collapse in the cutting process, the wear of the segment is also very serious, such as KARAMORI GOLD. Usually, most brands of similar type of sharp blade, cutting out the KARAMORI GOLD number is 30-60㎡,Yintian Tough Guy maintains high cutting speed, ensure the plate cutting quality fully meet the processing requirements, at the same time, the number of squares is far more than 60㎡.
    • The fourth category of customers:They mainly undertake various engineering large orders, time constraints, high quality standards and strict acceptance, the type of granite and processing requirements of each order are different.

This versatile saw blades improve the processing efficiency of such enterprises to the highest level of the industry, a substantial increase in economic efficiency.
    • The fifth category of customers:They attach great importance to corporate reputation, obsessed with the stone processing precision, stone processing acceptance criteria for any category and grade of the same stringent, meet the needs of customers with high quality used. So the blade requiring the purchase of high cutting precision and stable quality as one, at the same time, high yield, efficiency and life also ensures a certain angle and plate the level of. Yintian Tough Guy cut error was less than 0.2mm, the error is less than or equal to 0.1mm, the average length error and diagonal tolerances were less than 1.5mm, the tolerance of 0.2-0.4mm, the yield reached above 99%.
    • The sixth category of customers:They are processing aerated blocks, quartz stone, all use marble saws to cut part of the sheet, for they tried to use the price of the economy of granite saw blade, but the processing effect is not up to their standards, during the cutting processing, edge does not require perfect offangle without leaving the tail, all of these phenomena seriously affect their production efficiency and rate of waste stone. A high rate of material and reduce the cost, a cutting quartz stone and aerated brick granite blades have been trying to find.
    Mr. Guo, the dealer of Yintian in Yiwu International Market

    I have owned a store in Yiwu International Trade Market for 7 years, I used to buy sintered saw blades in Danyang, but more and more foreigners began to complain the quality and return goods in 2 years ago. So my business got into trouble and I was very upset. At that time, I heard of Yintian company from my peers. At first, I bought only 100 pieces including 100mm to 180mm to test. To my surprise, my clients reordered the saw blades proactively.Besides.an Australian customer called me overseas, and complained about my cheating in previous orders. He told me to provide only the same quality saw blades as that time I bought from Yintian. Otherwise he wouldn't do business with me. After hanging up, I was full of different feelings. From then on, I just sell Yintian's sintered saw blade, and now my business is running quite well.

    Mr. Hong in Malaysia, distributor of granite segments for single-blade and multi-blade

    I emigrated from Fujian to Malaysia in ten years ago and began to work on diamond tools business. There is a great need of granite segments for single and multiple blades in my local market. These cutting blades has very high requirements to the sharpness of segments. In first 2 years, I've visited many manufacturers in mainland and Taiwan, also their engineers, but their products are not customized to my needs. Later, my Fujian fellows introduced me an engineer Mr. Wu in Yintian Company. After several times of communication. I found him extremely professional in the formulation design and process treatment, especially in the sharpness controlling formula. We chatted enjoyably, then I tested their 1.8m and 2m granite segments. Nearly all of my customers reflected that time segments are much sharper than the previous, which cut quickly and neatly, thus greatly improving the processing efficiency. Now I've cooperated with Yintian for nearly 10 years, I am sure about their stable quality, they are worthy of trust.
