• All classical works of high quality engraving. Thanks to our integrated software on board Peace (optional accessory), all the typical operations of this kind of operations will be easily achievable.

• Technical light milling Machining where are required a degree of finish, accuracy and thermal stability (no drifts due to heating of spindle) particularly high.

• Implementation of fashion accessories. Thanks to the availability, as an optional, of our supplementary table of self-locking pieces, you can assemble a large number of flat bars of brass or other material able to use almost entirely throughout the work area. In this way the machine may have a range of machining particularly important without the presence of human personnel.

• Construction of molds even in the case in which both request the direct machining hardened steel, but where it is required a volume of removal of material compatible with the type of tool holder used and the available spindle power.

• Overall dimensions small compared to the actual working area available

• Spindle perfectly centered in relation to the structure that supports it and placed on the center of gravity

• All three working movements of the axes are on the spindle and then the work piece is stationary

In order to enhance the benefits of this innovative machine structure, more items have been improved gradually over the past 20 years up to the current version which includes the fruit of experience gained throughout this period of time.

Ball bearing screw characteristics and translation axes guides
– X and Z axis diameter: 25 mm
– Y axis 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 Y Z axis: size 25

Position transducer axes
Standard: incremental encoders on the screws.
On option: absolute optical scales.

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

This electrospindle is made by us and this in order to have an average duration “on the field” of over 10,000 hours of use. When a repair will be necessary, we’ll do it quickly and with particularly reduced costs.

– Tool holder DIN 69893: Hsk32/E
– Spindle power continuous duty (S1): 4 Kw
– Max torque spindle: 3.2 Nm

30,000 RPM version
Given the relatively low value of ndm (*) equal to 1,275,000, grease lubrication of the spindle bearings was deemed adequate to guarantee a sufficient lifetime.

40,000 RPM version
In this case the higher value of ndm (*) equal to 1,700,000, has led us to use the minimal lubrication of the bearings.

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.

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

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

9-position tool changer
It is a very simple device where the tools are simply deposited on a wire rack.

30-position tool changer
In this case instead was used a rotating axis for positioning in an automatic way the drum that carries the tools in the appropriate position. Note the presence of a micro security to prevent, in the case of macroscopic error by the operator, to mount a tool in a position already occupied.

Tool changer according a specific request
The structure of this model of machine allows to achieve in a simple way more models of tool changer having a number of positions particularly important (from 70 to 200).

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.
