P1040 Laser

Item number: P1040

The machine type  P1040 Laser is based upon the  Arnold Standard Glassworking lathe P1040.

 

Due to the design with a stable and torsion-free machine bed as well as  separate drive technique for each working head, this precision glassworking lathe is specially suitable for laser applications, e.g. in the laboratory and lamp glass industry.  The machine is designed as a compact unit including the laser aggregate and machine control and can be operated either manually but also fully automatically, for instance by loading and unloading of workpieces parts via industrial robot

 

Machine design

Machine design on a stable base frame for the acceptance

_ of glassworking lathe, laser system including beam control

_ as well as control unit, media supply and the required protection

_ devices – as a compact unit.

Glassworking lathe with a sturdy, torsion-free machine bed with

_ mounted precision linear guides, fixed on an aluminium plate.

Closed stainless steel cover above bed guidance for protection

_ against direct  influence of heat.

Moveable machine parts – working head left and right – are

_ mounted on pre-loaded guiding wagons.  Working heads are

_ equipped with quick clamping devices for automated opening

_ and closing of scroll chucks.

With all required laser protection devices with 2 manual

_ sliding doors, in feeding sector, where operator is working

_ for a generous access into processing sector. Protection

_ equipment is designed for a safe operation of laser unit

_ according to relevant safety prescriptions.

 

 

Drive technology

Each spindle stock is equipped with an own a.c.-servo-

_ motor running the spindle directly via toothed belt.

Spindle stocks are disposing of the following operating

_ modes: Synchronous drive of both spindle heads

_ (standard operation) or individual operation of each

_ spindle head

In both cases a reversing operation is possible

_ (switchable turning direction)

Drive of working spindles guarantees an exact control

_ even in lower speed ranges

Working heads equipped with own, one each a.c. servo

_ motor and integrated way measuring system. Positioning of

_ working heads is freely programmable via machine control.

 

Laser technique and beam control

Rofin Sinar CO2-laser, mounted according to slab-principle,

_ with an output power of 400 W (as an option up to 800 are

_ also possible). The slab laser does not require conventional

_ gas recirculation. Those precision tools are disposing of a

_ closed gas system („sealed-off“). The system can be operated

_ for more than 16.000 operating hours at an actual power

_ output without gas change.

Cooling aggregate for cooling down of process cooling water,

_ for cooling down electrode plates in laser. Cooling is done in

_ form of recirculation operation.

Beam control via mirror system starting at releasing point via

_ focusing optics up to the workpiece.

Option: Focusing optics with automated positioning axis. This

_ also enables a forming of laser beam for different applications,

_ like for instance automatic focal point adjustment on different

_ diameters of construction point or  changing operation:

_ cutting – joining – forming

 

Adjustment and control technique

Control of machine is done with a Siemens Simatic

_ S7-PLC-control unit, integrated in the control cabinet.

Process programming and – visualization with Lenze OPC

_ Touch Panel.

Programming with Arnold AEPS (Arnold Easy Panel System).

_ Process parameter and process running can be programmed

_ by e.g. process specialists, without any basic knowledge of

_ PLC programming languages.

Pyrometer for surveillance of controlled process running during

_ heating and joining period, for reproducible process

_ characteristics during automated constant operation.

Camera system for automatic glass edge measurement and

_ positioning of the workpieces which shall be joined in the focus

_ of laser with the following features:

_ - automatic glass edge detection for optimal axial positioning

_ - in the focus of laser

_ - automatic joining gap optimization – radial positioning of

_ - joining parts to each other to minimize the dimension of

_ - joining gap

_ - automated axial feeding – dependant on joining gap of

_ - working heads in order to   prevent faulty positions during

_ - joining process

_ - integrated 100%-process control to check joining zone if

_ - there are missing points after joining

Option: ARPAT (Arnold Remote Process Analyse Tool) for

_ documentation of all available contruction- and process data
