We hope that this article will help you to select a manual milling machine with knowledge. As usual, we do not confine ourselves to a simple listing of the functions of the instrument, but we try to give the reader a maximum of practical information, we try to disclose the reasons for choosing those or other characteristics.
What can a milling machine do?
The laurels of the inventor of a full-featured milling machine belong to the American Eli Whitney, who in 1818 received the corresponding patent. As in the case of other outstanding machines, a clear breakthrough was preceded by centuries of technical and production achievements and even ready-made constructive solutions. The first cutters and the first milling devices on a wooden frame (with a muscular drive) were used in Germany / Austria at the turn of the 17th-18th centuries. The improved Whitney technology was based on the rotational motion of the working blade and the translational movement of the workpiece in http://www.harryhilllive.com/bosch-1617evspk-variable-speed-router-review/, initially it was intended to improve the quality and productivity in the processing of metals (it still does not have an alternative, in terms of accuracy, at least). A little later, similar machines were used to work with wood. Only in the second half of the twentieth century there was a technical opportunity to milling with a hand-held electric tool – a light compact milling cutter, selflessly adored by millions of wooden masters.
Despite the fact that it seems that this machine is very difficult – in fact, the milling cutter, in a sense, is one of the most simple electrical tools. Unlike other units, here the tooling is fixed directly to the shaft of the electric motor (spindle), so the design is spared from the presence of gears, belts, reducer. The power unit (head) of this unit may have a serious power comparable to stationary machines, but the main accent all the developers have made on the high speed of the tooling movement, direct transmission allows the milling to be accelerated to an impressive speed. Any router is equipped with a mass of auxiliary devices designed for precise feeding and productive sampling – all kinds of stops, clamps, guides, templates. That’s the functionality of these elements are the most serious requirements.
Not only wood is subject to a manual milling cutter, without special problems (with special equipment), one can “talk” with plastics, non-ferrous metals, plexiglass, composites, artificial stone and so on. Depending on the purpose and some design features, several types of this tool stand out (edge, stationary, rod, specialized – cutting, for inserting locks, for gypsum board, for tiles, lamellas, thorns …), but the most universal and commonly used is the mobile sucker rod milling cutter. In this case, the head of the machine moves up / down the guide bars, which are rigidly connected to the support sole. Thus, the cutter is strictly vertical, smoothly plunges into the material of the workpiece to be machined to a given depth, until the upper movable part touches the adjustable stop. After that, the operator moves the tool in a horizontal direction, and the main work is performed by sharp edges of the rotating cutter.
