Take advantage of the hole wood milling cutter

1. scribing edge with arc design, impact resistance, wear resistance and better life than ordinary products to enhance the three-fold drill bits for wood. 2.2 scribing edge to prevent small wood chipping. 3. Take hole for open circular groove, was taken out of the hole is very smooth. 4. Take alloy hole wood milling cutter look beautiful, durable, high precision, good wood cutting tct saw blade and wood milling cutter performance, there is sufficient bending strength and wear resistance Good advice: Try using a short edge of woodworking tools, edge mouth is too long or too long blade will cause vibration and deflection, resulting in damage to the tool. 2, we recommend using a shank diameter of wood milling cutter. 3, the normal use, an appropriately wood sds plus auger bit is very important, old ones, there is a cross-sectional, not round, severe wear and jacket tapered bore, can not provide sufficient clamping force, resulting in flying off, vibration or broken hilt. Also, do not think that the case must be reliable new jacket. When the wood milling cutter handle was found after clamping shank contact marks or uneven grooves, indicating a slip case and jacket bore distortion, then the need to immediately replace the jacket.

The use of wood milling cutter in life

Shovel teeth molding wood cutting tct saw blade tooth back curve is generally circular curve made Archimedean spiral or circle with the wood milling cutter center offset, in order to ensure that the amount of change in a number of wood milling cutter teeth back after regrinding after a small angle . Archimedes spiral equation in polar coordinates is: R = C θ Where:? R-- radially; C-- constant; θ-- polar angle. Archimedes spiral tooth back angle at any point after the calculation according to the formula: Formula: R-- tooth back to any point in diameter; R '- tooth back at any point the first cutting disc derivative of the path; θ- - tooth back at any point of the polar angle. Be seen from the above equation, α changes with θ. Since the value of θ itself is large (close to 2π), and a smaller variation range (less than ε =), so the change amount α is small. According to calculations, in general, change α is not more than 1 ° 30 '. So, in fact, can not consider changes in the posterior horn. When using the arc center offset curve for tooth back curve, although the changed angle α to be bigger, but still meet the requirements of the wood end mill cutter. After milling angle α on the working drawings are usually the amount of K by shovel teeth for labels.

How to choose wood milling cutter

Work object is a wood cutting tct saw blade tool or a wood composite, the metal material are different, much lower than the hardness of the metal, but the timber is uneven structure anisotropic material. In addition, most woodworking tools are not continuous wood milling cutter conditions at work. These conditions result in much higher woodworking wood milling cutter tools metal wood grass cutting tct saw blade tools, equipment to withstand the impact is greater than the metal wood milling cutter tools. When selecting woodworking tool material, hardness, strength and toughness properties of the tool material, must adapt to these features of woodworking tools.

How to polish wood milling cutter

Do not know your wood milling cutter inserts are high-speed steel or alloy of it, but also by the end of your teeth wood cutting tct saw blade or teeth of a week, two weeks after the tooth angle, usually after two about 22 °, about 1 12 ° after variety of grinding is not the same, folding back on the wheel axis is 90 ° out of drill bits for wood, and if the arc is back open helix angle in degrees, minutes after the end of it after one or two angles, after about a 10 °, after about 2 20 °, using a bowl-shaped or disc wheel open, open when the attention backlash angle. There is generally end teeth installation angle 35 ° to 45 °, as well as end tooth rake angle, about 5 °, weeks before the tooth angle wood milling cutter open up to you, if it is a general wood milling cutter, grinding surface on the front edge Okay.

The work principle of wood milling cutter

When the wood milling cutter and workpiece edge line axis coincident or close to the edge line of the workpiece, the situation will be very serious.

1. Check the machine's power and rigidity to ensure that the needs of the wood milling cutter diameter can
wood sds plus auger bit
The use of the machine.
2. Spindle tool overhang on the shortest possible, reduce the impact of the wood milling cutter and workpiece axis position to shock loads.

3. Suitable for use in this process is the correct pitch wood end mill cutter, to ensure there is not much at the time of the cutting insert and the workpiece while vibration caused by engagement, on the other hand, when the narrow milling or milling a workpiece cavity to ensure that there is sufficient blade and workpiece engagement.

4. To ensure that the use of the feed amount per blade, so that when the chip is sufficiently thick to obtain the correct cutting effect, thereby reducing tool wear. Using positive geometry indexable inserts, resulting in a smooth cutting performance and lowest power.

5. Selection of suitable width wood milling cutter diameter workpieces.

6. Choose the right main angle.

7. Correct placement wood cutting tct saw blade.

8. Using only the cutting fluid when necessary.

9. Follow the rules of the tool maintenance and repair, and monitoring tool wear.

The application of wood drill bits

wood drill bits is a very commonly used tools, grinding a wood drill bits for a better work efficiency and quality are of great help! Well, here we go! More accurate wood drill bits holes: a dash dot dot wood drill bits two small holes with a diameter of 3-5 (the diamond core drill bit should be relatively sharp angle at about 90 degrees, a faster speed of about 700-1300 to Wuyi wood drill bitsing, for example) 3 and if the required hole diameter of 8 or less. Directly with a wood drill bits down. If the diameter of 8 or more points twice best wood drill bits. (General category) reaming countersunk head: a slow speed wood drill bits should, angle of about 120 degrees. (General category) countersunk screw some people directly with a large ground-type drill bits for wood. Such as the M8 screws, diameter 8.5 countersunk hole diameter 13, with a diameter of 13 direct ground type, middle left diameter 8.5 to about 30 long waterway hole: M12 tooth generally take a ditto ditto 2 3 To require the central through-hole with a diameter of 8 to first with a diameter of 8.5 bilateral first wood drill bits, then the diameter of 10.5 reaming, and then wood drill bits through the practice of direct 8 iron convenient row. wood drill bits grinding method, focusing on iron round nest chamfer wood cutting tct saw blade row.

The introduction of wood milling cutters

When optimizing the milling effect, cutter blade is another important factor, if at any time while participating in the wood cutting tct saw blade the number of blades is more than one advantage, but the disadvantage is that too much to participate in wood milling cutters the number of blades at the same time, at the time of wood milling cutters each a wood milling cutters edge can not simultaneously wood milling cutters power required and the number of participating in the wood milling cutters of the wood milling cutters edge related to chip formation, wood milling cutters edge loading and processing a result, the position of the workpiece relative to the cutter played an important role. When face milling with a wood milling cutters width ratio of about 30% larger cutter and the cutter location close to the center of the workpiece, so little change in chip thickness. When the Leads end mill cutter thickness of chip thickness ratio at the center of the wood milling cutters slightly thinner.

To ensure a high enough average chip thickness volume feed per tooth, you must correctly identify suitable for the process of the cutter teeth. Cutter pitch is the distance between the diamond cutting saw blade edge and effective. The cutter can be divided into three types according to this value - fine-toothed cutter, cutter teeth sparse, special fine-toothed cutter.
