One of the most versatile machine tools for carpentryand carpentry works - hand-held wood milling machine. With the help of this precision device, it is possible to perform a variety of woodworking operations. And with certain skills and sufficient skills of the master, the hand mill can serve as a tool for artistic wood carving in the base plane.
The machine consists of a large electric motorpower, compact frame and several guiding devices. The engine is designed to rotate the mill in the range of 12 to 24 thousand rpm, which provides a fairly clean cut. As a rule, a manual wood milling cutter is equipped with a speed regulator, the speed of rotation depends directly on the size of the used cutter. The larger the cutter, the smaller the speed of its rotation, in order to avoid overheating.
Mills with which wood mills are equipped,there are two types, the so-called end, for grooving grooves, grooves and cuts of the "swallowtail" type. And milling cutters, which are designed for processing the edge of the workpiece, straight, angular or shaped. End mills are divided into cylindrical, semicircular and pointed, sharpened at a certain angle. The assortment of supporting milling cutters can not be counted, their profiling is too diverse, the diameter of the head can be from 4 to 30 mm.
The milling cutter has an auxiliarya ring that limits the pressing of its cutting edge to the material being processed. Instead of the restrictive ring, a small ball bearing can be installed. The method for limiting the clamping of the milling cutter allows the use of special reusable patterns when the workpiece to be machined is rigidly aligned with the template and the milling cutter, using its bearing on the template, cuts the workpiece according to a given profile and size. Templates are made of a solid material, it can be multi-ply plywood, 10 mm thick, sheet textolite, aluminum or plexiglass.
Современный ручной фрезер по дереву имеет The mechanism that regulates the depth of the milling, the so-called elevator. The machine slides up and down on two vertical guide rods, while the milling cutter can be fixed at any point in height. For works that are often repeated, there is a three-position limiter, a revolver type, on which the milling cutter is lowered and in this position is fixed. For more fine adjustment in height, an additional screw stop is provided.
Also, a hand-held wood milling cutter is equippedmechanism of limitation for milling at a given distance from the edge of the workpiece. This is a special stop, which moves along two horizontal bars fixed at the base of the machine. After the final installation, the stop is fixed with two screws. If the length of this device is insufficient and the specified distance is not reached, then instead of the stop, guide rails are used, which can be installed at any point.
Important is the engine powerhand milling machine. Usually household electric hand milling machines install electric motors with a power of 1.5 kilowatts. But if the machine is used in a constant load mode, this power will not be enough. It is better to purchase a milling machine with an engine of 1.8 or 2.0 kilowatts. In this case, the power reserve is sufficient even for round-the-clock work.
