EC43 3 Axes with Pallet Loader

• Construction of molds in general. The very simple construction of the pallet allows blocking the work piece from the bottom of the pallet to have no overall dimensions due to the clamping brackets in the area in work.

• Machining of mechanical components for small/medium size.

• The presence of the robot loads parts and tool change with a very important number of tools allows to work 24 hours a day even without staff.

The main elements that distinguish the following machine model are:

• Z-axis stroke increased to 400 mm to allow mounting of components with an increased thickness.

• Installation of an automatically-locking pallet on the table. Great care was taken to ensure that the clamping surfaces of the pallet on the work table remain extremely clean. A safety device locks in each case further processing if a chip were to be present on the floor of locking. The clamping force on the vertical plane of this device is 100 KN.

• Automatic Device replacement with 12 pallet positions. In relation to the actual size of the workpiece to be handled, other solutions can be studied.

• External tool to the machine, and then in a “clean” position in relation to the work area, having 62 positions.

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

If required, it will be easy to make a tool change with a greater number of tools. Inside the tool change it is also possible to position the probe.

While the machine is working, the tool changer mount on a shuttle the tool that will serve to further processing. So this is an operation that takes place in masked time.

At the end of the current process, the tool below will already be fitted on the shuttle and this for a tool change time as fast as possible. As the processing resumes with the new tool mounted on the spindle, the tool will return it to its previous position, which is that this will happen again in masked time.

Pallet changer
The system used to bring the selected tool in work is largely the usual that is used to bring the pallet in work which then performs a dual function.

At the end of the machining process, the robot will proceed to place the pallet in its position and take the pallet required by the program from the carousel. Everything is perfectly visible from the movie callable directly from this web page.

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.

– Chip conveyor complete with rotating filter

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.
