Router bits for woodworking is a rotary cutter with one or more cutter teeth. Through the relative movement between workpiece and cutter, each cutter tooth cuts off the allowance of workpiece intermittently in turn. The installation methods of woodworking milling cutter are divided into two types: sleeve milling cutter with hole and milling cutter with handle; The structure of the set milling cutter has three types: integral type, insert type and combined type. Woodworking milling cutter is selected through three key points: spindle rotation speed, feed speed and cutting depth.

For the spiral cutterhead to work properly, it must be properly installed, and careful daily maintenance, please follow the steps below.
When the spiral cutterhead has been installed on the machine, the equipment power must be turned off before changing the woodworking carbide inserts.
Use an air gun or a brush to remove debris, dust, and other foreign matter on the knife shaft.
Turn the wrench counterclockwise to loosen the screw. Use an air gun or a brush to remove debris and dust from the knife holder to ensure that the knife holder is clean. To prevent the blade from cracking or “edges” on the planed surface.
When changing a cutting edge, wipe the blade clean and rotate it 90 degrees. Note: there is a marked point on the surface of the reversible insert to ensure the same orientation and avoid the wrong replacement of the old and new cutting edges.
Gently press the blade and slide it a few times to make the bottom surface of the blade fit the blade holder. Lock the screw clockwise and the blade will automatically press against the blade holder positioning table. (Note: In order to ensure that the screws and screw holes will not bite and rust firmly, and to prevent it from being loosened next time, the screws need to be lubricated with oil when changing the blade).
Carefully check whether the blade is correctly placed on the blade holder to avoid cutting the blade or cutting edges when the blade is locked.
Check the Reversible Knives before use. If it is broken, please replace it immediately to avoid safety accidents and damage to the product. Check the screws frequently to avoid loosening them.
What are the advantages of dw735 spiral cutter shaft?
Firstly, if you replaced the cutter with spiral cutter shaft, that will overcome some problems of flat blades, and has the following advantages:
Spiral cutting surface, to ensure that the wood is not torn or tenon.
Segmented cutting, very small sawdust, easy to absorb and discharge.
Segmented cutting also leting minimal noise, more stable machine.
Among them, DW735 spiral cutter shaft is special R150 degree arc cutter shaft: on the basis of segmented cutting, realize point cutting and perfect planing. Point cutting makes the surface of wood more smooth and delicate; the wood chips are smaller to achieve perfect chip removal; the contact surface is smaller and the machine is quieter and more stable.
Advantages of spiral cutter shaft:
Spiral cutting surface: the high-precision design and manufacturing technology arranges the reasonable row of discarded blades around the cutter body to form a smaller cutting surface in unit time, so as to improve the burning mark and the tenon of the blade.
Very small sawdust: small cutting area per unit time, very small sawdust formed. It is easy to absorb sawdust in the Chinese and British dust collection system, making the working environment cleaner and more comfortable.
The planing effect is more smooth and delicate: the high design of cutter body and blade, plus the benefits of segmented cutting, is to make planing smooth and delicate.
Low noise: the noise value generated by the contact between the wood surface and the flat blade in the same time reduces about 30 to 50 dB.
The machine is more stable: in unit time, the cutting area is small, the friction is small, the cutting resistance is small, and the vibration amplitude of the machine is smaller, so it is more stable.
So much for today’s introduction of DW735 cutter head.
How to correctly choose the saw blade according to the woodworking saw blade parameters?2021-10-18T02:42:16+00:00
Woodworking circular saw blade is the most commonly used tool for wood products processing, but not all wood products are processed with the same woodworking circular saw blade. It is said that each lock corresponds to only one key, so different materials of wood require different Woodworking circular saw blade. There are many parameters involved in woodworking saw blades, such as: the choice of alloy type, base body, diameter, tooth number, thickness, and so on. The following tells you how to use these parameters correctly and reasonably to select the appropriate woodworking circular saw blade.
The first is the choice of alloy types. Commonly used types of cemented carbide are tungsten-cobalt (code YG) and tungsten titanium (code YT). Because tungsten-cobalt-based cemented carbide has better impact resistance, it is more widely used in the wood processing industry. The commonly used model in wood processing is YG8-YG15. The number after YG indicates the percentage of cobalt content. As the cobalt content increases, the impact toughness and bending strength of the alloy will increase, but the hardness and wear resistance will decrease. Choose according to the actual situation.
Then there is the choice of diameter. The diameter of the circular saw blade is related to the sawing equipment used and the thickness of the sawing workpiece. The diameter of the saw blade is small, and the cutting speed is relatively low; the large diameter of the saw blade has higher requirements on the saw blade and sawing equipment, and the sawing efficiency is also high. The outer diameter of the saw blade is selected according to different circular saw machine models to use the saw blade with the same diameter. The diameters of standard parts are: 110MM (4 inches), 150MM (6 inches), 180MM (7 inches), 200MM (8 inches), 230MM (9 inches), 250MM (10 inches), 300MM (12 inches), 350MM ( 14-inch), 400MM (16-inch), 450MM (18-inch), 500MM (20-inch), etc. The diameter of woodworking saw blades is mostly designed between 120MM-400MM.
The second is the choice of the number of teeth. Generally speaking, the more the number of teeth, the more cutting edges can be cut per unit time, and the better the cutting performance. However, more cutting teeth require more cemented carbide and the price of the saw blade High, but the saw teeth are too dense, and the chip volume between the teeth becomes small, which is easy to cause the saw blade to heat up; in addition, there are too many saw teeth. When the feed amount is not matched, the amount of cutting per tooth is small, which will increase the friction between the cutting edge and the workpiece , Affect the service life of the blade. Usually the tooth spacing is 15-25mm, and a reasonable number of teeth should be selected according to the material to be sawed.
The choice of woodworking circular saw blade requires reference of various parameters. In addition to the several parameters described above, there are some others, such as: thickness selection, tooth profile selection, aperture selection, etc. These parameters determine the saw blade The processing ability and cutting ability, and the choice of woodworking circular saw blades just affects your work efficiency and work results, and has a great impact on improving product quality and shortening working time. The above is about how to choose the right woodworking circular saw blade.
How To Make the Saw Teeth Sharp Again?
For any piece of circular saw blade, no matter where it is born or what material it is made of, they cannot avoid the fate of wear. Among the large family of saw blades, even high-performance multi-blade tools such as diamond saw blades、carbide saw, still need to bow their heads in the face of wear. The only difference may be that the wear occurs later.
In fact, the wear of saw blades has always been a headache for saw blade manufacturers and material sawing and processing companies. For producers, although they know that the market has very high expectations for the life of saw blades. But according to the current technical level and material technology, the saw blade manufacturer can be said to be powerful and has nowhere to use it. When faced with the endless chatter about the life cycle of buyers, they can only reply with consumables, and it is difficult to guarantee the use time as a reply.
From the standpoint of saw blade users, the high loss rate and high scrap rate actually mean that companies have to spend more money on purchases. Once the scale of the enterprise increases and the amount of saw blades increases, the problem of saw blade wear will eventually become an issue.
Judging from the above-mentioned interests of both parties, no one wants to have a very short life of the saw blade produced or in use. But the reality is that the wear of the saw blade is everywhere and occurs all the time. Many people think that only when the saw blade is in working condition, the saw blade will wear out. But in fact, even when the saw blade is in a non-working state, the wear of the saw blade will also occur.
From the perspective of the manufacturing process of a circular saw blade, whether the heat treatment process of the saw blade substrate passes the test, the technical level of the welding teeth, and whether the packaging and transportation can be fast and stable are all the links that will appear in the non-use stage of the saw blade. . Take the transportation of saw blades as an example. Wrong placement of saw blades and violent saw blade transportation will cause the saw blades to undergo changes in stress, and even the problems of tooth loss and wear during the transportation process.
Therefore, if a circular saw blade can be used for a long time, it is far from enough to rely on standard operation. On the contrary, from production to transportation, and then to use, any link cannot be ignored.
After a saw blade is actually working, as the amount of sawing tasks increases, the degree of wear of the saw blade itself will continue to deepen. Among them, mechanical impact wear and thermal wear are the two major causes of saw blade wear. Once the above-mentioned wear and tear are allowed to develop, the company’s own sawing cost is bound to be substantially increased invisibly. The final result is a decline in annual profitability.
Frankly speaking, we cannot avoid the wear of the saw blade. But after the saw blade is really worn, we can still make a difference, and then make the saw blade that is about to be scrapped “the sword is not old and returns to the edge.” According to the existing technology, in order to effectively make the worn saw blade be To use it efficiently, the most effective method is undoubtedly to sharpen the saw blade.
From the perspective of the saw blade grinding process, when a worn saw blade is sent to a professional saw blade manufacturer. Relevant grinding manufacturers will grind the saw blade at multiple levels and in all directions. It ranges from the leveling of the saw blade base to the fine grinding of the front angle, back angle and side angle of the saw blade. The complete set of saw blade grinding process reaches 18 steps.
After the above-mentioned multiple saw blade grinding processes, the performance of the ordinary carbide circular saw blade will be restored to the cutting performance of the new blade. It is imperative for the sawtooth to return to sharpness. For those saw blades with a very good foundation, such as high-performance multi-edged tools such as diamond saw blades, not only can they be sharpened more often than ordinary carbide saw blades, but the grinding effect is also better. good.
Of course, not all saw blades are suitable for grinding, for those with a very high degree of wear. For example, saw blades with large-scale tooth loss, or even saw blades with cracks in the substrate, basically lose the need for grinding. Therefore, for those companies that do not understand saw blade grinding, before trying to establish a cooperative relationship with saw blade grinding manufacturers, it is very necessary to ask whether their saw blades are likely to be repaired.
What are the common problems of woodworking circular saw blades?
What is the difference between the professional and ordinary woodworking circular saw blades?
Chinese brands can adequately meet the needs of diy use. The distinction between grades is the difference in durability, which is the service life, and also involves the production process, such as whether the thickness of the saw body is uniform, the concentricity of the outer circle and the inner circle, and the serrated The quality of the welding process seems to be very simple to make the saw blade, but it is difficult to do it well. For the user, the Chinese product technology is good enough, even for the big brands in Europe and the United States, a large part of it is produced in China. Yes, the staggered teeth are cut wood, and the ladder flat teeth are cut aluminum alloy.
How to define the specifications of woodworking circular saw blades?
Outer diameter-inner diameter-tooth thickness-number of teeth,
The label 210*30*2.0*45 means: the outer diameter is 210 mm, the inner diameter is 30 mm, the tooth thickness is 2.0 mm, and the number of teeth is 45 teeth.
What power tools can woodworking circular saw blades be used for?
Electric circular saws and table saws can be used. Of course, they cannot be used indiscriminately. The following conditions must be met:
The outer diameter of the saw blade must meet the maximum value of the electric circular saw;
The inner diameter of the saw blade must be consistent with the saw blade pressing plate, otherwise there will be problems such as failure to install or slip, the most important thing is that the saw blade must be consistent with the product.
Is there a distinction between left and right for woodworking electric circular saw blades?
It must be installed in the direction of the arrow marked on the woodworking electric circular saw blade, and the saw blade cannot be installed backwards.
Make sure that the direction of the saw blade is consistent with the direction of rotation of the saw blade (the arrow on the saw blade should point in the same direction as the arrow on the circular saw).
The inner pressure plate boss has a diameter of 30 mm on one side and 20 mm on the other side. Use the correct side according to the hole diameter of the saw blade you want to use. Incorrect installation may cause dangerous vibrations.
How to sharpen circular saw blades?
Note that the front-to-back ratio is 1: 3, The minimum remaining length and width of the tungsten carbide saw blade measured from the tooth seat must not be less than 1mm; it must be performed strictly in accordance with relevant operations, non-professionals cannot operate, and the correct method for repair The saw blade can only be used within a reasonable life span if it is not sharpened. If it is not properly ground, it will only reduce the efficiency and quality of the circular saw blade.
It is strictly forbidden to grind only from the front corner surface or only from the rear corner surface. This will greatly shorten the service life of the circular saw blade and also affect the next grinding status! Another important point is that the entire wear area should be fully sanded. The circular saw blade is ground on an automatic sharpener. If it is manually ground on a general-purpose sharpener, it will seriously affect the quality of use.
(The CNC sharpening machine can ensure that the grinding of the front corner surface and the rear corner surface is completely in the same direction.) In order to prevent large wear on the grinding wheel, it is necessary to leave sufficient side protrusions from the side of the sawtooth to the saw body. On the other hand, the largest side protruding part should not be greater than 1.0-1.2 mm on each side to ensure the stability of the saw blade teeth.
Try to ensure the space for chip removal, and avoid the situation that the chip groove needs to be repaired at the same time due to the grinding of the saw teeth.
If the tooth breaks down, you must go to the grinding center to change the teeth. When welding, pay attention to the appropriate welding sound or another solder, preferably with a high-frequency welding machine.
Leveling and stressing
If you want to use a circular saw blade to ensure its quality, you must use the leveling and stressing procedures. Do not use it because of trouble. Each time you grind, check the blade’s flatness and stress value. ? And correct. Leveling can reduce the tolerance of the blade’s runout, and add stress to the strength and elasticity of the blade. This
