EC1220

We repeat: we are talking about a machining center and not a “router” and then about a very specialized machine.

Even the removal capacity is not negligible. In this regard the machine structure is particularly robust and therefore the power available on the spindle is fully exploitable.

This solution allows you to have on one side a very large field of work and the other to contain, with respect to the field work performed, the overall dimensions of the machine.

Since the size of the work area very large, the Y-axis has been realized according to the scheme of a “gantry axis electric”, ie there are provided two electric motors, two screws and two position transducers for the translation of such axis. This solution allows you to have a very rigid construction of the machine at the same time limiting the weight of moving parts.

Compared to the solution in classical portal made by us with our model M1015H (with which it shares the spindle), however, has the drawback of posing a production cost of such axis substantially higher.

Noteworthy is the fact that both the guides of the Y axis that the support of the two screws of translation of such axis were made directly on the work table having a considerable weight (over 3,500 Kg the only work table!). The movable cross despite being made in welded structure (steel), was constructed according to the technology that provides for the filling of such component polymer with low density and therefore both the side of the work table (made of cast iron) which from the side crosshead gets the maximum damping effect of the vibrations caused by the tool in its movement of material removal and this guarantees a long life of the tool in work.

Note that the two screws of the Y axis are not rotating, but that is the nut that rotates as directly mounted inside the rotor motor which will also have a hole for passing inside the screw axis of translation. The above in order to minimize the inertia of the rotating parts. Indeed, the inertia of any rotating screw, given the stroke of axis Y, would be particularly important.

These two screws are both pre-tensioned. The pre-tensioning allows you to have a torsional stiffness and axial four times higher compared to a pre-stressed screw.

In order not to introduce any element of thermal distortion, the two motors housed inside the Y-axis of the moving crosshead, are liquid cooled.

Concerning the construction of the X axis, to note the absence of the coupling between motor and screw. The motor axis, of our construction provides the rotor mount directly on the screw drive shaft and this guarantees a greater roundness of movement for this axis.

Ball bearing screw characteristics and translation axes guides
– X axes diameter: 40 mm
– X axes diameter: 40 mm – Two screws present
– X axes diameter: 32 mm
– Screw pitch X Y Z: 20 mm per revolution
– Material: hardened and ground steel with ceramic material nut balls
– Dimensions roller block size X Z axis: 25 mm
– Dimensions roller block size Y axis: 45 mm

Position transducer axes
For all three axes are used optical absolute scales

The bearings used are of hybrid type, namely steel rings and ceramic balls.

Given the high value of ndm (*) equal to 1,920,000, has led us to use the minimal lubrication of the bearings.

This electrospindle is made by us and this in order to have an average duration “on the field” of over 15,000 hours of use. When a repair will be necessary, we’ll do it quickly and with particularly reduced costs.

– Tool holder DIN 69893: Hsk40/E
– Spindle power continuous duty (S1): 12.5 Kw
– Max torque spindle: 9.3 Nm

Rigid tapping
On this spindle can be mounted threading tools directly on the collect of the toolholder. The CNC will in fact synchronize the movement of the descent of the Z axis, taking into account both the number of revolutions and the programmed pitch of the threading tools mounted, to perform the tapping requested.

Cooling of the tool from the inside of the spindle axis
This is a particularly important characteristic of the implementation of which has not resulted in a reduction of the maximum number of R.P.M. that this spindle can have. When this option is present, it is added also a specific water pump joined to a filtering system of the liquid of higher quality having an impurity max 0.01mm.

(*) ndm (speed factor) = speed of rotation in RPM x mean bearing diameter in mm

NYou can not mount tools having a diameter greater than Ø 34 and you can not have access to the drum directly from the outside of the machine for inspection at the sight.

It is separated from the machine and this to so that should not be affected negatively by the vibrations generated by the normal use of a numerical control machine. You can program the machine is in a sitting position that standing.

We follow the philosophy of using two Pc IE:

Pc used as a Numerical Control
• Operating System Florenz (derived from Linux)
• RAM Installed Size 4 GB
• Dual Core Processor
• Solid state hard drive (SSD) having a capacity of 30 GB. On this Pc must be installed only the software of Cn. This data storage capacity is thus largely sufficient for all requirements of current and future data storage, even taking into account the natural evolution of Cn software and Linux will have in the coming years.

Programming Pc
• Operating system Windows 8.1 64-bit
• RAM Installed Size 4 GB (expandable to 32GB)
• Dual Core processor with integrated GPU
• Hard disk solid state drive (SSD) 240GB
• Monitor 22″ having a resolution of 1680×1050 pixels
• If considered appropriate, it is possible to install on this Pc any other program provided that is compatible with Windows

Selected Hardware
Both Pc are assembled directly by us and this in order to select the components of the best quality on the market and to have, thanks to the presence of a heat exchanger air/air, the maximum reliability in the time.

PearKey
• Sulla pulsantiera macchina è stata prevista una porta USB su cui inserire una chiavetta, normalmente reperibile in commercio, con cui determinare a quali programmi l’operatore a cui è stata assegnata tale chiavetta ha diritto ad avere accesso.
• Una singola chiavetta può personalizzare l’accesso ai programmi di macchine diverse e per ogni macchina possono essere determinati programmi diversi a cui tale operatore ha la possibilità di avere accesso.
• Se ritenuto utile su tale chiavetta possono essere memorizzati anche altri dati.

It is a PC dedicated to the exclusive use of the electronic steering of the machine and therefore does not permit the installation of other programs. The data exchange between the PC and the Master Link board is via an Ethernet cable made with special care. If the evolution of the soft NC would require more computing power (which in the past has happened more than once), you can replace its PCs with a more powerful at really very low cost.

In case the customer decides not to buy our software Peace complete with its Pc in Windows 10 environment, you can transfer data processing to be performed by the company network on cable (not via a wireless connection), or via USB stick.

PC Hardware Characteristics Used as Numerical Control
• Installed RAM 4 GB
• Processor Intel Dual Core 2Ghz
• disk solid state disk (SSD) 64GB

Input/Output Modules
The data exchange with the inputs and outputs (I / O) is via dedicated modules each of which is equipped with a signaling LED for each input or output to simplify any troubleshooting. The connection to the Master Link is via optical fiber.

Axis Drives
The drives are connected to the Master Link via optical fiber and are free of the usual electronic cards pilot. In other words they are constituted only by the power modules.

Basic Software
As operating system uses FlorenZ namely a modified version of Linux with proprietary software to meet optimally the needs of Real Time typical of a numerical control.

Drives Software
The most innovative part of this control is constituted by the fact that the whole part of the drives logic is contained directly within the NC soft, this solution that has permitted to abolish the usual electronic cards piloting drives. All to the advantage of a better degree of finish on the working piece, and especially of a greater reliability.

Diagnostic Software
Very many are the diagnostic programs and putting into service of the machine which, above, shows, by way of example, only some screens shots.

Software Calculation Proactively Working Time
Very useful can be the provision of know in advance, without requiring the real execution of the working piece, the actual time of a machining operation with a calculation error of a few seconds, and this also in the case in which the machine is carrying out in the same time a real machining. The calculation is performed by a virtual copy of NC in Windows programming Pc, while the data display and the interface to the user is carried out by our soft Peace.

Data Exchange with the Windows PC on which the Software is Installed Peace
It was achieved through a conventional network card and its crossover cable.

The manufacturer of this numerical control is D.Electron (Italy) – www.delectron.it.

Measuring Probe

Purpose of the measurement probe

a) To store the values of a new origin. For this purpose, within our soft Peace are present measuring cycles which store in an automatic way the reference origin of the machining to be performed.
b) To check that the work has been well performed. This kind of performance is not achievable with our software Peace, but with the use of a program developed by third parties.
