All the possibilities of precision mechanics: discovering PTFE

Posted on by admin

Massively used  in precision mechanics, Teflon is the trade name of polytetrafluoroethylene (PTFE), a polymer belonging to the class of perfluorocarbons, which are added other stabilizing components and thinners to improve the application possibilities.Teflon is the trade name of polytetrafluoroethylene (PTFE), a polymer belonging to the class of perfluorocarbons, which are added other stabilizing components and thinners to improve the application possibilities.

It is the material with the lower coefficient of friction known and has a considerable resistance towards external agents, a high degree of non-stick properties and resistance to low and high temperatures (from -200 ° C to + 260 ° C). It is therefore considered one of the most stable plastics materials from the thermal point of view, great to be worked in the cnc precision mechanics also.
The PTFE was discovered accidentally by Roy Plunkett in 1938, during an attempt to manufacture a chlorofluorocarbon for use as refigerante for the compression cycles.

Some of Teflon characteristics, such as the total chemical inertia (which is not attacked by chemical compounds, except that of the alkali metals in the molten state, high-pressure fluorine and some of its compounds), the complete insolubility in water and organic solvents , the fire resistance, over wing surface smoothness and all’antiaderenza, make it indispensable in precision mechanics for gaskets and the parts intended for contact with corrosive agents, in the engines, to reduce the friction of the exchange, for vehicle windscreen wipers, as insulating material and for many other uses in the mechanical, computer and food.

Brass in precision cnc machining, wath you need to know

Posted on by admin

In precision cnc machining, brass is an oxidizable alloy formed by copper (Cu) and zinc (Zn) and optionally other elements. They say the brass rails formed only of copper and zinc, ternary those in which there is another element and quaternary ones where there is a quarter of a chemical element that characterizes the league.

For the brass binary one speaks of α phase when the zinc content is less than 36%. These brasses have an excellent cold workability (drawing and molding) and a good hot workability. The alloys with a 45% higher percentage of zinc have no practical interest.

The copper-zinc binary, also in precision cnc machining work progress, alloys are normally machined by numerical control machine (CNC machining precision), but their toughness causes the formation of very long chips. To obviate this drawback it adds that of lead, remains completely separated from the alloy and, due to its lower melting temperature, is the last element to solidify. So, it will be distributed to the edges of the grains of the copper-zinc alloy making very short chips or even dusty and safeguarding cnc machining services.

The brasses are also referred to lead-dried brass and are used for the pieces machined on a lathe, such as valves and faucets. CuZn39Pb3, in particular is used for gears, pinions and for all those details to complex shapes requiring a machine tool working by removal of very high-speed chip.

Precision mechanics: the heat treatment of metals

Posted on by admin

In precision mechanics, among the processes performed on ferrous materials for the production of one of the heat treatment of precision mechanical components it is used to modify the molecular structure of the metal.

In the heat treatment the effect of heat allows the metals to enhance the characteristics depending on their use. of different treatment cycles between the heating and cooling phases can enhance the hardness and resistance capacity of the metals used in the precision mechanics.
The heat treatment of metals in precision mechanics has ancient origins that go back at least 4000 years ago when it was already used for the production of spears and knives by the high technological level. By heating a given metal in the presence of acids and chemical solvents capable of generating carbides and nitrides, to then be immersed in water and thus obtain already a primordial quenching technique.
In the mechanical precision of the quenching often it concludes the process of the heat treatment giving the component a hardness that can also be increased by a hundred times compared to the physical properties of the original metal.
Among the most used thermochemical treatments include the carboniturazione, carburizing and galvanizing, all these processes are executed directly from T.M.G. and forming an integral part of the process of realization of the components for the precision mechanics.

All about milling machine, the heart of precision mechanics

Posted on by admin

The milling machine is the heart of precision mechanics, a very important tool used in cnc machining services to work into complex shapes metal parts or other materials of spherical shapes.

There are two main types of milling machines, both with a horizontal plane x-y. The first, the vertical, has the engine mounted on a z-axis, for which the movement on three axes allows the machine to make holes or reaming; in that horizontal, instead, the motor is placed on a lateral guide and makes it similar to a large circular saw. It is mainly used to realize slots, grooves and continuous pockets.

In these two types of milling machine are added the so-called “machining centers”, which have a fixed desk, and the motorized head that moves along 4 or more axes.

The CNC milling machines have an accuracy of up to the order of microns (0.001 mm), although they require special working conditions such as an air-conditioned environment, a solid base of support, temperature sensors on the axles, optical guides.
Normally, milling machines are very solid, because they have to absorb the vibrations generated by motorized head without losing precision, why, when performing work on very hard materials or at very high speeds using special lubricants to optimize the cooling of the tip and to reduce the efforts.

Precision mechanics for industry: discover T.M.G

Posted on by admin

Precision mechanics is a discipline of mechanics that deals with the production of machine parts for the industrial, agricultural, medical.

One of the machines used for the construction and maintenance of these machines is the lathe. Its history is very old, there are traces from prehistoric times, when it was used to produce vessels.
Of course over the centuries it has been perfected, and today there are several types, specialized for the type of production.

The latest evolution in the field of precision mechanics of the lathe is to numerically controlled, also called CNC lathe (Computer Numerical Control).
It is a machine completely controlled by a computer, in which are inserted the parameters of the workpiece that is to be produced. The machine parts move in totally automatic mode, and the computer, during processing, the signals received by sensors that allow it to monitor the smooth running of the work. If, for any reason (such as tool consumption) sensors detect abnormalities in the production of the piece, the computer makes the necessary corrections during construction. The precision of the pieces obtained with this machine is measured in the order of hundredths or thousandths of a millimeter.

Nickel plating in precision mechanics processing

Posted on by admin

In precision mechanics processing, nickel plating is a treatment in which certain materials are subjected to modify the surface characteristics such as hardness and resistance to external agents. It is very useful in precision mechanics or precision mechanics for ensuring the corrosion resistance of manufactured pieces.
The process is distinguished chemical nickel plating and electrolytic nickel.

The first can be performed on various materials, from metal, glass and plastic. The procedure is also called electroless plating nickel and consist in a deposition of nickel without the use of electric current, but through the presence in the treatment of a chemical reducing agent, generally sodium hypophosphite solution. The main advantage is that the distribution of the thickness of nickel on the objects processed in the framework precsion mechanics is extremely uniform, even in the case of complex geometric shapes.

The electrolytic nickel plating in precision mechanics processing can only be performed on metal material. The pieces are immersed in specific baths and, through a passage of electric current, there atoms are deposited by a pure material bars, arranged according to some geometric principles. The nickel plating provides corrosion resistance that depends, in addition to the layer thickness, from its porosity, brittleness and adhesion
