Mesin laser dibagi menjadi kelas-kelas yang berlaku internasional berdasarkan kinerja dan risiko cedera mata dan kulit yang terhubung dengannya: Kelas 1 menawarkan keamanan tertinggi. Dengan laser kelas 4, radiasi laser dapat dipancarkan. Penggunaan peralatan pelindung (mis. kacamata pelindung) diperlukan di sini. Mesin Laser Trotec mengandung sumber laser CO2 atau fiber, atau sumber laser keduanya dalam sistem Speedy flexx.
How safe are Trotec laser machines?
By means of the closed design of the Trotec lasers, the laser user is optimally protected. This concept additionally allows for rapid and efficient extraction of dust and gas. The closed Trotec flatbed laser machines belong to laser class 2. Why only laser class 2? Laser pointers are built into Trotec lasers, in order to show the user where the laser impinges the material. According to the internationally valid standard, laser pointers with an output of less than one milliwatt belong to laser class 2.
Except laser machines with laser class 4
If the Trotec laser plotter is equipped with a hatch, the chassis has an opening through which the laser radiation can exit. Such laser machines thus fall into laser class 4. A similar situation results with Trotec lasers with galvo technology. The laser must be classified into laser class 4 if it doesn't have a corresponding housing. Lasers of the safety class 4 may then only be operated with special protective gear (protective glass, shields, protection goggles).
Radiasi laser yang dapat diakses dari kelas ini tidak berbahaya - bahkan dengan radiasi yang berkepanjangan, atau laser ditempatkan dalam cara yang tahan radiasi..
Mesin laser kelas 2:
Ini terdiri dari laser yang terlihat (mis. penunjuk laser dengan keluaran di bawah 1mW), yang hanya aman untuk mata dengan radiasi jangka pendek di bawah 0,25 detik.
Mesin laser kelas 3:
Radiasi laser yang dapat diakses dalam hal apa pun berbahaya bagi mata. Harap perhatikan juga pantulannya (mis. pada permukaan bahan yang reflektif). Trotec tidak memiliki sistem laser dengan laser kelas 3.
Mesin laser kelas 4:
Di sini, kerusakan mata dan kulit dapat disebabkan atau kebakaran dapat dipicu dalam zona bahaya laser. Dengan laser kelas ini, pengguna berkewajiban untuk sepenuhnya mematuhi ketentuan perlindungan.
Which safety class do the individual Trotec laser machines have?
Which protective devices does a Trotec laser have?
All Trotec laser machines are CE-compliant and thus meet the essential safety and health requirements of the EC Machinery Directive 2006/42/EC. Here you will find an overview of machine-specific safety and protection devices, which make our lasers one of the safest in their class all over the world.
Interlock safety switch
Cladding elements, side covers/front hood and the protective cover serve as protection for the laser. These covers are fitted with interlock safety switches. If the protective cover or another interlock-secured cover is opened, a signal sounds and the laser machine immediately interrupts the laser process. Thus ensuring maximum safety for the user at all times.
All-round light curtain system for SP laser cutters
A moving light curtain system around the safety bumpers on the X-axis define an all-round protection zone around the work area. If the user enters this protection zone, the laser is stopped immediately.
For all closed laser systems, e.g.: Speedy Laser Engraver series or SP Laser Cutter series, the acrylic cover provides extensive protection from the laser light. Depending on the laser source, different protective covers are used. For example, laser machines with a CO2 laser source have a blue acrylic cover, while machines with a fiber laser source have a green cover. Due to the coloring of the acrylic glass, the laser light is completely absorbed, thus providing extensive protection for the laser user.
CO2 laser source: Blue protective cover
Fiber laser source: Green protective cover
The temperature sensor enhances safety during laser cutting
Temperature sensor with warning signal
Some materials (e.g. acrylic) tend to flame, especially during laser cutting. The specially developed temperature sensor alerts the laser user when the temperature in the work area exceeds a critical value. The operator can react instantly to the acoustic warning signal and interrupt the laser process. Walaupun demikian, mesin laser tidak boleh dibiarkan beroperasi tanpa pengawasan.
Safety switch for immediate interruption of the power supply
In a dangerous situation, the power supply can be interrupted by means of various safety switches and buttons. The laser process is immediately stopped.
Main switch: Main power supply is disconnected
Key switch: Motor, laser source and electronics are de-energized
Emergency stop button: Electric circuit is interrupted, the laser beam and all movements are stopped
Laser safety training
When installing your Trotec laser machine, you will receive important instructions regarding safe handling of the laser. In addition, our Trotec Academy offers a comprehensive training program.
