Cutters for wood used formanufacturing edges, grooves, concessions and other things. Thanks to them on the wood products manufactured profiles and grooves. milling method allows you to process almost any flat and contoured surfaces. The milling cutter is a device which rotates the tool at a high speed around its axis and causes it to perform a reciprocating motion which may be helical, rectilinear or rotary.
To perform such processing usedspecial tools - milling. Milling machine or router is equipped with an electric motor, which is located on a sustainable basis. Its base may be a table which is connected via a pin with the motor. Set assumes a horizontal washer, which is necessary to determine the working depth. Let us consider the features of the selection cutters for woodworking.
Variety of cutters for woodworking
There are different types of mills: cylindrical, face, shaped, angular, circular, terminal and drills. Each species has its own characteristics, which play an important role in the choice of this tool. Let's look at them in more detail. The horizontal form cylindrical milling machines are used. Processed via their surface must be flat. The teeth on these machines can be straight and screw.
Straight teeth can process planesmall width and are suitable for screw broad surface. When using these devices, any axial forces, which will depend on the inclination of the axis of the tooth. To avoid such inconveniences by specific bits and two rows of teeth are arranged in different directions. Performance of face mills is much higher cylinder counterparts.
They are used on vertical millingmachines, and the upper edges of the teeth have profiling. The ends are minor cutting edges. A basic function is performed by the outer side edges. Angle cutters are used in those cases when it is necessary to make the grooves on the corners and the corner profile grooves form. These cutters can be dvuuglovymi and single-angle. Single-angle pattern are arranged on the conical surface and totsah edge. In dvuuglovyh cutter edge are close to the two surfaces. This arrangement allows for smooth operation, as compensate the axial loads. To reduce wear, the vertex angle cutters are made rounded.
Mills may differ form the rear surfaceedges. The edges can be straight or curved shapes. To work with profiles in the relief milling tools used knives spiral curves. Pointed cutters are applied, if necessary pazoshipnyh producing compounds. They are made in the form of a cylinder, on which there are cutting edges.
Cutters are divided into types according to the method of the devicespindle. For this characterization tool is terminated and Shaft-mounted. End mills have another name - the tail. They are fixed and the collet chuck. A Shaft mounted cutter should be screwed into the spindle. Mills are twisted in the opposite direction of traffic. In addition, there are milling roughing and finishing. Drafts are used for quick rough handling, and it is possible to obtain a smooth surface due to the finishing mills.
Choose a milling cutter
To select the cutter should take into account the characteristics ofmachine. Each machine has a passport, which indicates Shaft cutters range, which can be installed on it. These characteristics determine the appropriate diameter of the push-cutters. Most often it is in the range from 80 to 180 millimeters. Another important indicator is the method of attachment to the spindle. Milling cutters with an increased number of holes with a diameter set by means of special bushings and cartridges.
If the machine has no mandrel thread for nuts,Then, this model requires special hydraulic bushings. Moreover, the cutter can be used which are used in mounting and the collet nut. When choosing a cutter should pay attention to the teeth alloy. From its strength will depend on the fence material to be treated in many ways. Moreover, the cutter can be checked for accuracy of manufacture.
Remember that some manufacturersCutters are made of poor quality. So we looked at the basic features of the choice of cutters for woodworking. Acquainted with them, you can go to the store sang these components.
