ROVER GOLD 1232
Numerically controlled machining centres ROVER GOLD 1232

As guarantee of the quality of its products and services, BIESSE has been certified ISO 9001 since 1995 and works in accordance with the UNI EN ISO 9001:2015 norms.
Most of the technological components assembled on the machining centres is produced by companies of the Biesse Group or by world-wide known companies included in the Biesse "Register of Qualified Suppliers", which have strictly cooperated with Biesse through the years.
The running tests of each machining centre include the following stages:

Intermediate control of operating units and pre-assembled components
Non-stop running test as machining simulation for a minimum period of 10 hours
Control of X and Y axes precision and positioning repeatability by means of an interferometric laser (VDI/3441 norm)
Gauging of the X and Y axes through a software function: the values detected during the laser tests are elaborated by the N.C. and transmitted to the axes drives in order to improve the positioning precision
Functional tests for routing and boring operations on panels positioned on all the machine origins

Structure
All the machine structural components have been designed with a CAD product for solid modelling which allows to determine the possible structural distortions caused by static and dynamic loads. The correct dimensions of the most critical components are elaborated by a software for finite elements structural calculation which, by simulating the work conditions, allows to determine the most stressed areas which need strengthening.
The accurate structural design grants to the BIESSE machining centres maximum rigidity, high precision in time and perfect machining finishing even during heavy-duty working cycles.

Base frame
The machine frame is made of thick electrowelded steel sheets, properly strengthened in the most stressed areas.
The mechanical machining are performed in a single setup to ensure maximum accuracy.

Upright beam
The upright beam, mobile in the longitudinal direction (X axis) consist of a X-carriage and a Y-beam of electrowelded steel structure: thick steel sheets and reinforcing transversal elements minimize the twists generated by the material stress relief generated by metal machining and obtain the highest levels of precision.

Transversal and vertical carriages
The transversal carriage (Y axis) and the vertical carriage (Z axis) are made of an aluminium light alloy casting which is stabilized and then machined in a single setup for maximum precision.

MOVEMENT OF CONTROLLED AXES
Axes drives and motor systems
Biesse uses Brushless motors, controlled by digital axes drives.
The interfacing between axes drives and numerical control is digital.
The digital system Mechatrolink allows the following:

Higher machining speed, since a portion of the toolpath is controlled by the axis drive instead of the numerical control
Higher working precision, thanks to a faster data processing
Higher reliability, thanks to a reduced wiring system which eliminates electrical interferences that may occur on analog systems
Reduced machine stops and downtime, thanks to the errors diagnostic with explanatory messages displayed directly on the N.C.

X and Y axes transmission system
The operating unit moves along the longitudinal axis (X axis) and transversal axis (Y axis) by rack and pinion system (a solution that BIESSE is been using for years) which grants high acceleration and movement speed.
BIESSE uses a tempered and ground rack with helical teeth and a precision reducer with single pinion.
The preloaded pinion system eliminates backlash and therefore grants smoother movement and maximum positioning precision.
Both rack and pinions are built in accuracy class 6 (DIN 3962 norm).

Z axis transmission
As the operating unit moves in the vertical direction (Z axis) with a relatively short travel, BIESSE uses the ballscrew system with preloaded nut for backlash compensation and repeatability in positioning precision. The movement is transmitted to the screw through a flexible joint.
The ball screws are built in accuracy class ISO 5.

GUIDES OF CONTROLLED AXES
Axes guides
All axes moves on tempered and rectified steel linear guides by preloaded recirculating balls bearings.
Each balls bearing is equipped with 4 sliding gaskets of which 2 internal and 2 external, to protect the bearing from chips and dust intrusion.
The size and the great pitch between the guides grant high precision and perfect machining finishing performed by the operating units.

MANUAL CENTRALIZED LUBRICATION SYSTEM
For an easier maintenance, the machine is equipped with a centralized lubrication system with 2 greasing points. At each time interval set in the numerical control, a message automatically pops up on the screen, signalling the need for lubrication. The operator can use the pump supplied with the machine to manually convey the lubricant to 2 distributors, which sends the grease to:

Recirculating balls bearings of the X, Y and Z axes
Rack and pinions system of the X and Y transmissions
Ballscrew nut of the Z axis transmission

ELECTRIC SYSTEM
The machine is equipped with controlling devices (i.e. electrovalves, input/output modules, etc) which are assembled next to the devices they control, and are provided with the electronic circuits necessary for their interface with the fieldbus; this solution greatly simplifies the electric system, with obvious advantages for diagnostics and maintenance purposes.

Electric cabinet
The machine can be powered at 380/400/415V - 50/60Hz.
The electrical cabinet and the internal components comply with the CEI EN 60204-1 and CEI EN 60439-1 norms.
The auxiliary transformer supplies the connection voltage for the personal computer, the air conditioner and the electrospindle cooling fan, avoiding the use of the middle neutral wire, not always available.
The electronic equipment is powered by a stabilized 24V DC power supply.

Inverter
Inverter for electrospindle and boring head with power output adequate to the selected configuration.
Static frequency converter.
Inclusive of:

Display for frequency visualization
Display for tool rotation speed visualization
Display for diagnostic messages
Automatic control of tool rotation deceleration
Brake resistor for power dissipation
N.C. programmable tool rotation speed

Air conditioner for electrical cabinet
It allows:

the perfect working of all the electronic components inside the electric cabinet, even at very high temperatures, up to 40°C (104°F);
a dust-free environment, since there are no aeration fans.

CONTROL SYSTEM
Numerical Control
Control cabinet with Windows-based PC and control system card BH660.
The new Biesse technology WRT (Windows Real Time) extends the functionalities of Windows operative system by making it work in real time and able to directly control the machine avoiding not necessary hardware and increasing reliability and performance.
Since the software that controls the machine runs directly on a personal computer and not on a dedicated hardware device, the system architecture is greatly simplified, granting greater performance and reliability.

Desktop Personal Computer
Main technical specifications:

CPU Intel(R) Core i
8 GB RAM memory
500 (SSHD) GB hard disk or superior
19" LCD
Dedicated graphics card
keyboard
mouse
DVD reader
USB ports
Ethernet card for network connection to an office PC

These technical specifications may be subject to updates without prior notification.
Since the personal computer controls the machine processes BIESSE does not allow the installation of additional non-authorized software, under penalty of losing warranty.

SOFTWARE
Statistic report
Machine statistics is an software environment capable of collecting general information on machine events in order to monitor productivity and reliability over time.
Customers can choose directly which events to be recorded, in example the machine set-up, production, authorized pauses, lubrication cycles, etc.

Emergency recovery procedure
This function allows operators to restart an interrupted working due to a machine emergency stop. The program restarts exactly from where it was interrupted, by following a specific procedure. The working can be restarted when the emergency stop happened during:

A routing cycle with the electrospindle
A drilling cycle with the boring head
A cutting cycle with a blade
An automatic tool changing cycle
Any ISO instruction programmed movement

The introduction of this functionality avoids to discard half-finished components, which sometimes are made of valuable materials (rare woods, etc.). It also allows operators to save time in case of long programs execution.

Tool life calculation function
The NC memorizes the distance covered by each routing tool and compares it to a value set by the operator.
When this set value is reached, a persistent warning message is displayed on the screen.
This message will be displayed each time a given tool has reached the value set by the operator.
An hardware output (alternate or continuous, chosen by the customer) allows the connection of an external device (for instance a flashing light or a siren) which will be activated when the message appears on the screen.
