Since 2013 we have updated the machinery with a new lathe with size until 1 mt with a major precision in the realization of the parts.
Our factory has many machines including:
NUMERICAL CONTROL MACHINES FOR TURNING IN PLATE
Called also Lathe CNC (Computer Numerical Control), represents the best evolution of the machine we are talking about. It can do everything the other machines described above do but in a total automatism controlled by a computer. The parametres of the part wanted were put on the right program and the machine elements move driven by the computer to which, simultaneously to the processing, arrive the signals from the different laser put on specific points in order to have always under control the good way of the process. The precision of the pieces obtained with this machine is very high, close to cents. In this case the operator control only the data shown by the computer and sometimes the sampled products
NUMEROUS MANUAL LATHES
The lathe is a machine used in the processing of a piece put in rotation. The most used lathe to the plate is quite simple as construction, driven by belts attached with the crankshaft or powered with the engine put inside a right protection on the frame of the lathe itself. it is composed by a cast iron bench fixed by two side pedestals. On the left side it is fixed the pulley steps that change the rotation speed of the form of wood or the terminal. On the opposite side a tailstock movable and that slide on the bench serves to keep the metal disk on the center. Between the pulley and the tailstock there is a support fan maintained on the necessary high by a pressure screw.ON the support there are severeal holes, in which is introduced a pin used as support to the utensils driven by the turner.
These shears serve to cut discs and circular crowns and if they have the parallel guide.also stripes of undefinite lenght. They are composed by a frame divided into two parts. The first part supports the two trees: oblique the lower, horizontal the higher; it is possible to adjust the high of the higher part depending on the thickness of the metal.The trees on one side have two equal diameter gears and a handle, on the other side two sharp steel rollers. The second part of the frame is merged "gooseneck" and it is necessary to keep centered the disc. The guide move on a square bar united with the first part of the frame and it is movable towards a little gearwheel meshing in a rack. A special pressure screw make immovable the guide during the cutting operation. The use of machine is simple: once put the guide tip center near the cutting rollers on the same size of radius of the disc to be cut, put the metal sheet near the rollers closing the central screw of the guide and with the right hand turn the handle until the disc is completely cut.
The shears guillotine have the function to cut sheets, paper, cartoon, metal, plastic materials. It is a cutting cold thanks to two blades: one fixed to the horizontal bar assembled between two uprights, while the second one is fixed to the horizontal slide to the work plane, put on the high side of the machine. This can fall vertically so the two blades meeting each other work like a guillotine cutting the sheet fixed on the work plane; in this way the cutting line is perfectly between the two knives. The fall of the mobile knife is preceded by the "press-sheet" that has to stop the sheet metal during the cutting operation. If there isn't the right balance between the charge of "press-sheet" and the resistance of the metal sheet, during the cutting operation the sheet may be deformed along the side.
They are divided into flat presses or with alternative moving and rotary presses or rollers. The flat presses use the energy of a flywheel, set in rotation by an electric motor, to move the slide towards one or more connecting rods. They are becoming more and more used the "presse servo", mechanical presses without flywheel where one or more brushless motor are directly connected to the command tree and to the kinematics of the press. The use of this kind of press allows a better possibility to change the slide run during the production, thanks to fact that these motors allow a rapid direction change. The "servo presse" if completed with a force sensor are very used during the assembly application where it is necessary the processing monitoring. The rollers presses are motorized directly on the axis of the rollers towards hydraulic or electric motors with special reducers.
The lathe is a machine used to work a piece set in rotation. Processing takes place removing a chip and it is called turning. The parallel lathe is a machine used in the mechanical. It generates solids of revolution and it is mostly used to work metals. The working cycle is composed by the rotation of the piece, while the tool put on a turrel move in a parallel direction with the rotary axis. The piece can be cantilever mounting on a chuck that projects from the driving head or be supported between the chuck and the tailstock, put on the axis in front of the chuck on a adjustable distance. When the piece is cantilever mounted it is possible work it in a flat way (turning flat), moving the tool in the radial direction to the axis of rotation. The parallel lathe allows processing based on rotational symmetries: cylinders, cones, spheroids, solids of revolution whose generating stereotyped.
The drilling is composed by a base on which is fixed a column; on this column there is the worktop, a cast iron table where fix the pieces to work. On the top it is possible to put a vise; It can vertically slide and rotate, the actuating mechanism can be rack or hydraulic; the small versions are setting on a worktop, the bigger ones have a base put on the ground. On the top of the column there is the head of the drill where there are all the moving mechanical parts. There is the change of speed that can be belt or gear; usually the belt transmission is used for drilling machines with manual feed or with the tip diameters of less than 30 mm, while the gear transmission is used on drilling with automatic feed, or with the tip diameters over than 30 mm (this is because the belt transmission principally use a form of rolling friction and tends to slip when subjected to very high loads). An electric motor generates the driving force transmitted towards a belt or gear to the spindle, that is, the rotating shaft on which are fixed the utensils. The spindle move vertically and it is connected to a wheel, that moved in a circular way by the operator allows the utensil to rise and fall.
