Laser engraving machine safety precautions

-
No matter what we do, safety is always the first element. For the more dangerous thing like laser, safety is more important. Let me introduce the safety precautions of laser engraving machine.

  • when co2 laser machine is working, the operator must stay with co2 laser machine to avoid unnecessary loss. Think of the machine as a friend who is inseparable.
  • During co2 laser machine working, the upper cover of co2 laser  machine must be put down in case of laser beam deviating to hurt people.
  • Because inside laser machine there are laser part and  high pressure part,etc. So it is  is banned to dismantle laser machine by non-professional worker.The laser cutting machine is not a toy that can be disassembled at will.
  • All parts of the machine must be fully reliable grounding, in case the static electricity cuts.When the insulation inside the appliance is damaged, the electricity flows from the ground to the ground, and people don't have to worry about getting an electric shock.
  • Because this kind of laser is not visible light, and equipment are strictly prohibited placed near flammable and explosive substances, in case the laser deviation to fire.
  • Any irrelevant total reflection objects or diffuse objects are prohibited inside laser machine in case  the laser beam is reflected out to hurt people.
  • The operator must observe laser machine at any time during working. (such as irregular processing,the abnnormal sound of machine, the temperature of circulating water,etc.)
  •  It is banned to push and/or to pull the laser head and its gantry during the machine electricity process.
  • The machine environment is without heavy pollution such as strong magnetic interference and strong electricity.
  • when the voltage is instable, it is banned to open laser machine. Or one regulator must be used.
  • It is prohibited to use laser machine if no be trained. 
  • The continuous working time for laser machine can't exceed 5 hours (In midway it is  needed to rest more than half an hour)
  • Water cycle must be kept clean, water temperature cannot exceed 20 degrees-30 degrees (suggested the pure water)
  •  it is strictly prohibited to open laser machine when maximum data appears in ammeter state. In case the laser power is broken and to  shorten the laser tube life.
  • Laser power used basic limit (i.e. no more than max. 20mA  of  ammeter)
  • if the machine hasmalfunctions or fire  please immediately to  cut off power supply.
Well, the above is almost all safety precautions. For general laser manufacturers, the manufacturer does not take any responsibility for the above problems, so we must be careful ourselves.

CO2, Nd YAG & Fiber lasers - which is right for me

-
With so many options on laser marking systems available today it is not surprising that many people get confused with which is the most suitable to their application. Many people don’t even know that the term “laser”, is actually an acronym – Light amplification by stimulated emission of radiation – which explains the process by which a laser beam is created. The basic theory of this is simple. A gain medium (the material that is used to create the laser light), is excited using either light or electrical energy to generate photons (the laser light). All of this is happening in a closed cavity, with a completely reflective mirror at one end, and a semi reflective one at the other. When the light bouncing around inside gains enough energy, it escapes through the semi-reflective mirror.    These high energy photons are then focused to a small spot (much like you did at school when you used a magnifying glass to focus the sunlight to burn things!). If it is a vector laser, this beam

What is the advantage of a laser cutting machine

-
Image
There are quite a few advantages to laser cutters vs other processes.(I do feasibility studies for potential clients full time for a laser cutting machine builder, so I'll try to explain without sounding biased) Typically, the alternative for a laser cutting process is a blanking press or a turret punch. A blanking press has a special cutting tool for each shape. A turret punch has a number of small tools and punches out a part by cutting a limited number of hole sizes and some line shaped blades for the outer edges.  A laser cutter traces the outline of a part with the laser melting the metal, and an assist gas blasting the molten metal out of the cut. Some advantages of a laser cutter :  Lower power consumption: a typical blanking press or turret punch consumes 50kW of power in total. A 4kW laser system uses 10kW of power total typically. Safety: A blanking press has a large blade that moves rapidly up and down, and doesn't necessarily have safet

CO2 Laser Tube Used Information

-
1. Before using, please ajust the position of water pipes  based on the principle,that is , to inflow from water inset into laser tube and outflow from its water oulet. And keep water fully inside laser tube without bublble.Then ,turn on the power supply. Requirement: the cooling water is used soft water like distilled water or pure water.And please attention that the temperature of water used, which should be controlled between 12 degree and 30 degree.So the temperature of water is not cooler than 12 degree and not hotter than 30 degree. Specially in summer,it should change water or stop water chiller work and rest some. In cold area, Please attention that Do not let water frozen insider laser tube. Especially,when laser machine is power off, please let the water out from laser tube to avoid freeze to break laser tube.( Attentions: customers who use alternating current must let the water box grounded). 2.The supporting points of laser tube should be a quarter of whole laser tube.I
