Many people, when they hear the word around, which is the tool, or turning, which is the operation, comes to mind the typical image of a potter molding the clay, and that image is perfect to start talking about turning, and then bring to our field, engineering, industrial or mechanical (photo by Javier Diaz). The principles apply to this type of turning, they are for everyone else, of course, change tools, operations, rates, materials and some parameters that we will see throughout the article. If I see a much longer article, I will in two parts, that is not too much data, you annoy the first day of the week. Since we started with the potter's wheel, explain that this is a machine, which initially was driven by human-powered, more specifically, by operating a foot pedal continually transforming the reciprocating movement of the pedal (operated by the person ) in rotary motion at the plate where the pieces are turned. Although this system is the most common, there are many other varieties, you can see an interesting variation in the minute 4:45 in this video, where a man spins a large stone in the bottom of the drill, which by their shape and placement, harnessing the power of inertia in it, to rotate the dish. As you can imagine, with the modernization of all trades, this has not been an exception, and we could say that the greatest advance was to use electricity, such as drive wheel. Even these days, football teams looking for potters to his defense, since then. The tools of a potter, a part of the drill, are mainly the hands that shaped the clay, but also often help timber with different shapes, sponges and rags to soften and thread cutting. So, as I said before, the beginning of turning a potter, and a parts of lathe machine are the same (relatively speaking), and gradually we will see. First we go for the machine, the lathe. It is a parts of lathe machine tool, whose most characteristic feature is that the piece we make, is anchored to a part of the machine, and has a rotation around an axis (as in a potter's wheel, clay spins on the plate) parts of lathe machine. Its main parts are:. head. Located at one end of the bench and contains one hand, the gears that transmit motion to the plate that holds the piece, on the other hand, the turner manipulates levers to achieve different parameters on the lathe, and finally the plate, that through a system of clutches, holding the piece for us milling. tailstock. It is a moving head, which can move onto the bed, and the tools that are typically mounted, usually bits, to perform operations on the axis of rotation of the workpiece. main carriage. As its name says "principal" is the important part of the lathe, on which are mounted piece machined tools, and on the lathe, regulates the movements of this. This device, which holds the tools, you name holder tower or turret. " Of course, there are plenty of other machinery and accessories in a lathe, but for now we are left with this. Since it is sufficient to explain briefly, where a piece lathe. Before entering the turning process should be clear that in a conventional lathe, can only be machined cylindrical or revolution, or parts that rotate on an axis that is aligned with the axis of the machine parts of lathe machine. Of course, this axis, need not always be the same. To be sure, examples of parts of lathe machine of revolution: vases, legs of chairs and tables (if they are round course), a pawn (chess piece, etc. Mainly need a lathe, a lathe, tools and material to make (but I'm funny. ) The turner, place the material, usually round bar (which may be steel, brass, plastic, wood. ), at the plate, and using a tool and a mechanism in this, tighten the grip on the piece, so that when you start to turn, not be thrown out. When the lathe machine set up, the room starts spinning at the speed that you set, and on (using the handle you can see in the picture) the main carriage, which has the perfect tool attached, and under this approaches the workpiece, the lathe is regulating the movement of the car, and makes the tool advances in one direction or another, starting material, and giving it the shape and size wanted. In this Youtube video, you can see how the piece rotates the jaw chuck, and as the main carriage, he gets closer to the workpiece and machining. In this case, the movement of this tool is not directly controlled by the lathe, but with a CNC, their movements are programmed. I tried to close the comments, but do not know. If you do me a favor, says the new blog. or I know!

A CNC parts of lathe machine is a type of rotary engine in which all movements are controlled with a storable program. In contrast to a NC lathe CNC machines have the most memory for programs and an RC interface, which is also read CAD drawings and can be programmed directly. To work with CNC machines, it is important to create the necessary processing before the CNC program. This can be done either directly on the parts of lathe machine (Shop Floor Programming), with the help of media (CD, floppy disk,. ) or via a dedicated network (DNC). Programming is basically in accordance with DIN 66025, in addition, observe the manufacturer's instructions. Letters (T, G, M,. ) is called the "address", the digits (0-9) as a "sentence". The start of each program is to "Oxxxx" or "% xxxx" describes being "X" is replaced by numerals and may be the beginning or the end be, for example a job number parts of lathe machine. Then a technology called row is created in this line have information on tool number T, spindle speed S. and direction of rotation of the spindle M03 (clockwise CW) / M04 (anti-clockwise CCW) must be present. Basically CNC programs should be as short and concise as possible. CNC kits contain the digits 0-9 and may have different meanings in a program. Prior records must always be addresses, because the control detects a sentence not alone. For example:. Addresses and records are grouped into so-called line, all the commands in these lines are processed independently to the control of the machine. The lines themselves have to end up with a command string corresponding thereto (eg,) are completed. Each refers to the CNC program (specified by the manufacturer) or to the parts of lathe machine zero (self-adjusting) workpiece zero point. The parts of lathe machine zero point is the beginning of the coordinate system and in most cases identical to the Refernzpunkt (X0. 000 000) and can be moved as needed with the necessary program instructions parts of lathe machine. The workpiece zero point in Z describes the finished workpiece cut to length in the final size plus about 1 / 10 mm allowance for subsequent finishing. These zero points are set manually when setting up the parts of lathe machine in the Geometric control in the X and Z. For CNC machines there are, as well as for other rotary machines, a variety of tools for almost all common operations. The main tools are various inserts for machining round or square material, as well as drills and taps. For some years there may have also driven tools to help you as milling on conventional CNC lathes perform or engravings set. Mention should also be specific measurement tools for measuring produced parts. One of the main features of a CNC parts of lathe machine is controlled with the possibility to use in a single pass several different tools for a variety of functions, without the tools to equip only during the operation. Even in simpler machines had up to 99 tools can be programmed. The disadvantage of such machines is often Platzmagel in the area of ??the machine, so that often only a maximum of 4-5 tool holder come to boatbuilding. Special machines (CNC turret machining centers) but can accommodate up to 50 tools already built-in holders. On more modern machines is a high degree of automation possible with the help of feeder and discharge systems, some machines can also perform independent measurements, thus making the operator more relieved and improves productivity parts of lathe machine. Such operations can be made very economically, since qualified personnel is often only needed for setting and parts of lathe machine setups. Working on CNC lathes is both a workload for the operator, since a once stored program is executed repeatedly during a spin observed in a hand or mechanically driven conventional parts of lathe machine always the editing process and intervene if necessary in him must. On the other hand, the preparatory works are also complex, because during set up or mentally ahead of the thought processes of the later work (and partly programmed) must be. high purchase costs (plus parts of lathe machine tools), but what are the big price decline in the sector of electronic controls less and less. From an economic point of view is worth the purchase today of a conventional automated parts of lathe machine tool only in exceptional cases. . . . .
