Polishing Of Extra Long Wood Drill Bit
2021年1月15日In the current decoration operation, it is often difficult to drill due to interference from door and window frames when drilling. Most of the workers now For the extra long wood drill bit, then there is an extra long wood drill bit . So how do we need to polish the extra long wood drill bit?
First, check whether the drill bit is bent and whether the cutting edge is intact, and then hold the middle and front part of the drill bit with one hand. This hand is regarded as the 0 points and is close to the position above the middle of the grinding wheel of the grinder. Hold the tail of the drill bit with the other hand and move it up and down. Sharpen both sides of the drill. Note that the two blades are the same length and can be measured with a ruler. Also, note that the angle between the centerline of the drill bit and the knife edge is about 45 degrees. On another special grooved grinder, the transverse cutting edge perpendicular to the centerline of the drill bit was sharpened again. When drilling, the bit is stable, the resistance is small, the positioning contact surface is small, and the hole is round, and the perfect bit is ground.
No matter what kind of grinding, you need to pay attention to the method and method, and the same is true for the grinding of TCT circular saw blades .www.jeejatools.com

People who are not in the woodworking industry may not have a special understanding of TCT circular saw blades, but in fact, the use of TCT circular saw blades has become more and more popular. So, for TCT circular saw blades, do you know how to use it is the most correct?
In order to make the circular saw blade play its best performance, we must use it in strict accordance with the specifications. For saw blades of different specifications and purposes, the angle of the blade head and the form of the base body are different, so try to use them according to their corresponding occasions.
The size and shape accuracy of the main shaft and splint of the equipment have a great influence on the use effect. Check and adjust before installing the saw blade. In particular, the factors that affect the clamping force on the contact surface of the splint and the saw blade and cause displacement and slip must be eliminated.
The above are some key points for proper use of TCT circular saw blades. For more details, please visit: extra long wood drill bit .www.jeejatools.com

When using tungsten carbide hole saws, it is often found that Tungsten carbide hole saws have the phenomenon of removing tungsten. Therefore, in view of this phenomenon, let us see if there is a better way to solve this problem.
(1) Cleaning of tungsten carbide workpiece Firstly, clean the tungsten carbide workpiece with cleaning fluid to remove the oil on the surface of the tungsten carbide workpiece, and then rinse the tungsten carbide workpiece with water.
(2) Clamping: Clamp the tungsten carbide workpiece so that the tungsten carbide workpiece can be rotatably fixed on both ends of the electrolytic cell.
(3) Prepare the electrolyte, add one ton of water to the electrolyzer, then add 50kg Na2CO3, UOkg potassium sodium tartrate, stir to dissolve.
(4) To remove the coating, please use a tungsten carbide workpiece as an anode and a stainless steel sheet as a cathode. Turn on the power supply, make the tungsten carbide workpiece rotate in the electrolytic cell, make complete contact with the electrolyte, and electrolysis reaction occurs. The current density is controlled at (200 300) * DL (A·!!! 2), the pH of the electrolyte is controlled at 10-13, the temperature is controlled at 20-80°C, and the electrolysis reaction time is 12 hours.
(5) Clean and take out the tungsten carbide workpiece after electrolysis, and rinse its surface with clean water. By adopting the above technical scheme, the tungsten carbide workpiece is removed by an electrochemical method. The electrolyte was prepared with Na 2 CO 3, potassium sodium tartrate and water. The electrolyte is non-toxic, environmentally friendly, harmless to the human body, and can be recycled. Secondly, the electrolyte only needs to be discharged once every two years, and the cost is low.
However, no matter which method is used, it must be used with care. After use, you must pay attention to the maintenance of tungsten carbide hole openers, Diamond cup grinding wheel and other workpieces to make the workpieces longer service life. www.jeejatools.com

As a grinding tool, the Diamond cup grinding wheel is suitable for removing corners, solder joints, burrs and burrs on the surface of metal materials, and repairing uneven surfaces.
Another type of grinding wheel is mainly composed of a large grinding wheel and a small grinding wheel. The diameter of the big wheel is 26 inches, which is about 0.66 meters. The small grinding wheel is used to stabilize the entire grinding wheel and help change the direction of travel of the grinding wheel. Its maximum load capacity can reach 120 kg, so it is suitable for most people. Even when driving on the road, the user can drive freely.
Diamond grinding wheels are widely used to grind high-hardness materials and precious materials that are difficult to grind with ordinary grinding wheels and require high quality. For the grinding and cutting of non-metallic workpieces such as cemented carbide, ceramics, glass, agate, gemstones, semiconductor materials, stone, etc., it is also suitable for titanium alloys.
Most industrial diamonds are used to make abrasive tools. The hardness of diamond is extremely high, 2 times, 3 times and 4 times that of boron carbide, silicon carbide and corundum respectively. It can grind extremely hard workpieces and has the advantages of high grinding efficiency, good wear resistance, low grinding force, low grinding temperature and good processing quality. Therefore, it is more and more widely used in the grinding of cemented carbide and other superhard cutting tools, as well as the cutting and grinding of materials such as glass and gems. www.jeejatools.com

The Bi-metal hole saws is directly produced by using the heat-treated bi-metal hole saws. The bi-metal made high-speed steel saw teeth of high alloy steel fuselage has many advantages, such as less vibration and faster sawing performance, and more stable anti-cracking during sawing operation.
1. The service life of the hole saw is prolonged by 30% by adopting bi-metal material.
2. Adding 8% cobalt to the material makes the sawtooth harder. It can cut a wide range of materials such as wood, gypsum board, artificial marble board, plastic products, non-ferrous metals, aluminum, steel plate, stainless steel plate, etc.
3. The uniquely designed variable tooth hole saw can not only achieve fine cutting of equal tooth hole saw, but also achieve the advantages of fast cutting and easy chip removal of variable tooth hole saw, which has dual functions.
4. Compared with other hole saws, it is not easy to pull teeth, drop teeth and long saw.
5. The cutting depth reaches 38mm.
6. The cutting diameter ranges from 14mm-210mm.
7. Precautions for use: When cutting wood, lift the electric tools up and down to facilitate chip removal. It is best to use coolant when cutting metal materials to prolong the service life of hole saws.
