Tag:China Cemented Carbide Industry

According to the "China Cemented Carbide Industry Research and Investment Prospect Report (2019 Edition)" released by Shenzhen Limu Information Consulting, the cemented carbide industry is a mature market worldwide, with major manufacturers distributed in China, the United States, Europe, Japan, etc. Country and region. In recent years, industry competition has been fierce, and global cemented carbide production has grown steadily. It is estimated that global cemented carbide production in 2015 will be about 70,000 tons, a year-on-year increase of 2%. China is the world's largest producer of hard alloys, with cemented carbide production accounting for about 38% of global production.

　　From 2000 to 2007, China's cemented carbide production increased steadily year by year, from 8,189 tons per year in 2000 to 16,500 tons per year in 2007, with an annual compound growth rate of 10.53%; from 2007 to 2009, affected by the global economic crisis, China's cemented carbide production maintained a steady state, with an annual output of around 16,500 tons; from 2010 China's cemented carbide industry began to gradually recover, from 2010 to 2018, the industry showed a volatility, with an average annual compound growth rate of 7.25%, 2018 China's cemented carbide production was 38,500 tons, an increase of 11.59%.

　　Since 2005, except for the year-on-year decline in output and export volume in a few years, China's cemented carbide production and export volume have shown a steady growth trend. During the period of 2009-2018, China's exports of cemented carbide products showed a rapid growth trend. The export volume of alloys increased from 3,347 tons in 2009 to 9,246.45 tons in 2018, with an average compound annual growth rate of 11.95%.

　　In 2018, the top ten enterprises in China's cemented carbide industry output accounted for 60.84% ​​of the country's total cemented carbide production, and the industry concentration is high. However, the industry has not yet established a perfect mechanism for the survival of the fittest and the unfair competition mechanism. The blind development of hard alloy enterprises and the low-level redundant construction of low- and medium-end hard products still exist in large numbers, affecting the technological progress of the industry and weakening the high-end and high added value. The product development capability will further increase the concentration of high-end, high value-added cemented carbide products in the future.

Q&A of Tungsten Carbide Spiral Cutter Shaft in Woodworking

Tag: woodworking tools, spiral cutter shaft

Model:
1. Floating models: the blade is flat and directly locked on the blade body
2. Pressing block model: the blade is erected and locked in the blade body by pressing block
Type
3. Light cutting (suitable for softwood): with 14×14×2.0 mm knife
4. Heavy cutting (suitable for softwood and hardwood): with 15×15×2.5/30°mm, 15×15×2.5/37° knife, 30×12×1.5 mm blade

The working efficiency of the spiral cutter used in the four-way planing can be increased by several times, and its main characteristics are safety, environmental protection, energy saving, small cutting resistance and long and durable processing time, which makes the condition of the traditional cutter to be grinded once or several times a day completely changed.

Discard type spiral cutter to extend the grinding time, high working efficiency, and even the use cycle can reach more than half a year to replace the blade. It develops rapidly in the field of woodworking tools. In the future, it can surpass the use of existing welding tools. With the rapid increase of woodworking tools output, the manufacturing cost of woodworking spiral cutter is significantly reduced, and the price is closer to the price level of traditional tools. Accept discard type blade. There will be more and more users of a spiral knife, which will significantly improve the development of spiral cutters.

Also, the use of solid wood material preparation panel reflects the advantages of the spiral knife, which not only dramatically improves the production efficiency, but also saves a lot of traditional cutting tool purchase costs, which is the guarantee of product upgrading to a higher standard.

So the tenon cutter for dining table and chair completely change the shortcomings of the traditional welding cutter in use. It does not need to change the cutter frequently, nor does it bring the precision error and consume more working hours after grinding. It shows an excellent performance in significantly improving the processing environment and improving the output and quality at the same time.

Owning one or more planers is a standard equipment requirement of every woodworking enterprise. The traditional blade type machining for common press planing can't adapt to the pace of modern machining. The common blade has a lot of noise and rough machining accuracy in the process of machining, and it needs to change the blade frequently. After grinding, the adjustment of the cutter is time-consuming and stressful, which is a big problem for the operator. Now the abandoning type spiral cutter shaft completely solves the above issues. It can be used for at least half a year after the blade is installed once, which not only reduces the trouble of frequent tool change but also saves most of the working hours, bringing more significant economic effect to the enterprise.

The vertical shaft cutter is also the same as the press planer. Now, the vertical shaft cutter does not need to worry about this. The abandoned spiral cutter has various products with external diameter and height on the vertical shaft. From the outer diameter of 60mm to the external diameter of 160mm, the height of 20mm to 140mm (the extra-long cutter can also be customized) can be covered, which is more the gospel of wood processing.

The wonderful planing effect even reaches the perfect degree, especially the mahogany furniture industry and the panel material preparation factory, which is also one of the most widely used.

The perfect combination of abandoning type spiral cutter shaft spiral cutter head and abandoning type blade, together with the imported top equipment and superior processing technology in Europe, is the theme of the woodworking market in the future.

Looking Forward to 2020, We Will Build a Dream and Sail Far

Tag:reamer,nail cutters,CNC inserts

Time flies like an arrow, day and moon shuttle, unconsciously 2019 with my full memories and harvest is about to quietly enter the end, 2020 is also slowly ushering in to us.

In this year, Relink is committed to providing customers with tungsten carbide solutions.

A Brazilian customer needs to customize a special reamer, but it is difficult to find a supplier because of the complex process. The technical department of We has been docking with customers three times before the final drawing is finalized. In order to meet the requirements of customers, we have tried many ways. Finally, it took two and a half months to complete the customization process of the new product.

In this year, We still pays attention to after-sales service. We don't panic or hide from customers' complaints.

A Bulgarian customer customized a set of standard nail cutters, but they could not be put into use normally. Relink follows up patiently to find out the reason for the difference of the machine. After studying the differences, our technology department provides solutions to solve the problems smoothly. Now the customer's equipment has been put into use.

In this year, Relink paid more attention to the user experience of customers.

Uk8135 Cnc Inserts Increase Your Steel Turning Productivity by 30%

Tag:CNC inserts,CNC tool brand,CVD coating

The turning of steel parts seems to be a very simple process to the layman, but in the actual processing process, people often encounter troublesome situations, such as chipping and scratching the machining surface to cause deterioration of surface roughness. There are many similar problems such as sudden chipping of the inserts when the chips are rolled into the workpiece, and the tool is not wear-resistant. These problems virtually reduce processing efficiency and increase processing costs. Based on this, the biggest "time killer" in modern production is inserts replacement, production interruption, and finding CNC inserts suitable for each application solution or material.

As an emerging domestic CNC tool brand, Relink attaches great importance to the research and development of insert material and groove shape. By researching and analyzing the processing characteristics of various materials, we have developed suitable geometries and materials to meet different cutting conditions. 8135 is a super strong general grade widely used for steel turning, and its excellent performance is shown in rough, semi-finishing and finishing under high-speed interrupted turning conditions. Coupled with GF, GT, GR three long-life inserts, each cutting edge can handle more parts, thereby reducing the number of downtime caused by insert replacement. In addition, a longer tool life prevents sudden fracture and reduces rework and scrap, and can operate with higher cutting parameters. The result is that your workshop can increase the production efficiency of steel turning by more than 30%.

How does this happen? The matrix of the 8135 insert uses a strengthened bonding phase to effectively resist the high-temperature plastic deformation of the substrate. At the same time, a functional gradient layer with a high bonding phase content is prepared to more effectively control the crack growth of the coating. So that the matrix has both toughness and wear resistance. With the thickened advanced CVD coating, the cutting edge can withstand high temperature, thus converting to higher cutting speed, and making the service life of the cutter more predictable and longer, improving the safety. Therefore, the average production efficiency of 8135 insert can be increased by 30%.

It is not empty to say that our inserts can improve the production efficiency of steel turning by more than 30%. There are a lot of internal experiments and customer feedback that have confirmed this argument.

Based on the excellent material and good chipbreaker geometry, the wear of the crater is minimized in the actual machining application of the insert. Whether it is roughing or finishing, the tool life has been significantly improved. The insert life is increased by more than 30% and the production efficiency is increased by more than 20% compared with the insert of a company originally used. When customers in Chile use WNMG080408-GT UK8135 to process wheels made of 55 # steel, each cutting edge can process 80 wheels with a depth of 0.8 mm, which is a 33% increase from the previous 60. It is completed at a cutting speed Vc = 253m / min and a feed speed f = 0.24mm / r.

Points for Attention in Using the Blade of Wood Planer

Blade is an indispensable part of wood planer, which is used to plane wood. So, what should be paid attention to when using the blade of a woodworking planer?

In the normal cutting state, because of the high speed of the cutter shaft, the centrifugal force on the blade is far greater than the cutting force. If the radial extension of the blade is too large, the cutting force will be increased, and the degree of injury caused by accidental contact of the hand will also be large; if the extension of the blade is inconsistent or the tooth chipping is damaged, the cutter shaft will be affected by the rotating unbalanced force and the cutting force will be uneven, and the workpiece will fall sideways due to the unbalanced cutting force, or bounce due to the periodic impact; if the blade is too narrow or the fastening is not firm, it will be in the strong centrifugal force Under the action of, the blade will produce asymmetric sliding in the radial direction, and even cause the blade flying out to hurt people.

1. The planer must be equipped with safety protection device, otherwise it is forbidden to use.

2. The planer shall be stable and operated by both hands. When planing large surface, the hand shall be pressed on the material; when planing small material, the finger shall not be less than half of the material height, not less than 5cm. It is forbidden to push after materials by hand. Do not wear gloves.

3. The planing amount shall not exceed 1.5mm each time. The feeding speed shall be kept even, and the force shall be light when passing through the planer. It is forbidden to return the material above the planer.

4. Planing wood with a thickness of 3cm and a length of less than 40cm must use a pressing plate or a push stick, and it is forbidden to push it by hand. Wood with a thickness of 1.5cm and a length of less than 25cm shall not be processed on a planer.

5. In case of knots, it is necessary to slow down the speed of pushing materials. It is forbidden to push materials on knots by hand. Old plates must be cleaned of nails, mud and sand. If the planed timber has cracks and other defects, it must be treated before planing.

6. The blade must be switched off and locked. It is forbidden to extend your hand into the inner side of the safety guard board to move the guard board or remove the safety guard board for planing.

7. The blade weight of the same planer must be the same, and the clamping plate of the tool holder must be consistent. The blade weld beyond the blade and the tool with cracks shall not be used. The screw for fastening the blade shall be embedded in the groove and not less than 10 mm away from the blade arm.

8.Operate the machine according to the number of people, cut off the power supply and lock the door.

How to Realize Marking in Tc Cold Rolls

Each cold roll steel bar manufacturer has its own trademark, many of which have been added to the steel surface during the rolling process. How does this trademark appear on the surface of steel bars?

The cold roll mark type has letters, characters, symbols or spaces between the ribs.

How does our company make the mark, and after receiving the order, our sales staff will actively communicate with the customer whether the roll needs to be marked. Most companies will specify the marking requirements in the purchase order, such as how many letters, the width of the letters, a few pieces of the TC roll need to be marked, and so on.

At present, our company mainly uses laser engraving machine to mark the roll. According to the customer's requirements, set the characters and sizes in the computer, and then set the engraving program, the machine can automatically mark.

Following are some markings engraved as order request:

125x82x15 PR 8.5 TC cold rolls with marking LDCA D8.5

 Ø150xØ90x20 PR 8  tungsten carbide cold roller with marking blanks ribs

 160/90/20 PR 10  TC wire mesh rolls with marking TS

After the customer gets the finished product, the tungsten carbide cold roll is installed in the rolling mill, the production line is started, and the rolling of the steel bar begins. In the final step of the rebar rolling, the disc circle passes through the three rolls, and the surface appears marked after coming out.
