It’s a dream of many to build a house - cozy, comfortable, warm, beautiful, durable, true place of a family well-being for many years, but there is always a question how much it will cost?
In any case building the house of your dream at all stages is better to entrust to the professional.
MAGR - one of the leading machine-building firms in Ukraine. Since 1998 wood processing equipment with the trade mark MAGR has had good reputation not only among national, but also foreign consumers. Hundreds of different machines work on big and small enterprises of Ukraine, Russia, Moldova and other countries.
The assortment of the equipment designed and produced by the Ukrainian machine engineers is quite diverse. These are band mills ("Nominal", ("Nominal- M", "Fermer"), service equipment for them, original multiedgers, lines of merging of part blanks on the length, press- clamps for pasting boards and logs, complete sets of machine tools for manufacture of cylinder logs - here is not full list of MAGR production.
In this article, we shall give the detailed information about the equipment for manufacturing details of beam from cylinder logs.
The advantages of wood house building are known and obvious. High ecological and esthetic parameters comfort and availability of initial raw material - all this makes it popular to build cottages, recreation centers, children's playgrounds, and other buildings and constructions from cylinder logs.

Picture 1

Cylinder log of the definite size (diameter and length) with such technological elements as cross-section notches, so-called "cups", longitudinal stacking groove and compensatory saw cut is considered to be a ready detail of beam (picture1).
Cylinder machine tool CЦ- 6.5 (picture 2), designed by the experts of MAGR, is capable to execute all operations necessary to get ready beam details.

The technological sequence of manufacturing of details is shown on picture 3

Initial part blank (log) is installed in the necessary position on the machine tool between driving and non- driving centers. Lengthways, rather slowly, the carriage of the machine tool on which the control panel and executive mechanisms with electric drives a rotating part blank (30-100 turns/ minute) moves. Speed of moving of the carriage can smoothly be adjusted with the help of the frequency converter. Fast turning (4000 turns/minute) cylinder milling cutter with six knifes provides a cylindrical surface of high quality (picture 3а). Processing of a log is carried out by one or several passes of the carriage, thus processing can occur at movement of the carriage in both sides.

Picture 3а

For one pass, the milling cutter is capable to remove up to 60 mm on the diameter. Usually we recommend carrying out the last pass with clean, that is with smaller speed of submission of the carriage and with the maximal frequency of rotation of the part blank. The diameter of the received cylinder, depending on purpose, can vary from 160 up to 280 mm. The maximum deviation from the set diameter at length of 6,5 m does not exceed 2-3 mm. For prevention of vibration of the part blank, which can arise at processing cylinders of small diameter (less than 180 mm) with big length (more than 5 m), the lunette is stipulated on the carriage.
Cylinder part blank is fixed from a crank, with the clamp stipulated for this, and for one pass of the carriage by the combined milling cutter longitudinal stacking groove is carried out (picture 3b)

The cups are placed on a log according to the specification and are made by the same combined milling cutter (picture 3c). Thus vertical submission is carried out automatically. For marking the cups the machine tool can be completed with an electronic ruler.

A disk saw (picture 3d) carries out compensatory saw cut up to 70 mm in depth.

The marking and making the cups takes certain time for which cylinder the machine tool “cylinders” nothing that is does not carry out its basic function. To increase productivity of СЦ-6,5, MAGR offers machine tools which are intended for making cups on cylinder part blanks.

First, we shall consider adzing stationary machine tool CB-280 (Picture 4). It is unusual because narrow tape saw, the so-called "fret-saw" (the scheme of work of the machine tool on picture 5) is the cutting tool here. Practically all known “cup cutters” cut the cups with the milling cutters having certain diameter that demands presence in use of standard sizes of milling cutters of all diameters of cups. The capacity of drive of such "cup cutters" is rather considerable and makes from 5,5 up to 11 kilowatt.

Picture 5

The offered machine tool allows making a cup practically of any diameter in a range from 160 up to 280 mm without change of a tool. Smooth adjustment of diameter of a cup is made by means of rotation of a flywheel with the control over a scale. On the machine tool the cups under a corner 90°+ 45° of a relative axis of a log can be made. If it is necessary, it is possible to make a so-called "face" cup. The work is carried out by one electric motor, capacity 1,5 kilowatt.
One saw can make about hundred of cups, log diameter up to 200 mm.
For operative work directly on a building site the small-sized portable device for cutting cron cup УНВЧ - 200 (picture 6) is offered. The device can make cups, under a corner 90° to an axis of a log, and under a corner up to + 45°.
