  Answer：

  The practical features of laser marking machine

  The laser marking machine is used as a processing means. There is no interaction force between the workpiece. It has no contact, no cutting force and small heat influence. It ensures the original precision of the workpiece. At the same time, the material is more adaptable, and it can make very delicate marks on the appearance of various materials and the durability is very good; the laser engraving is exquisite, and the lines can reach millimeter to micron magnitude. Marking made by laser marking technology is very difficult to copy and change, and is extremely important for product anti-counterfeiting. Semiconductor laser marking machine.

  

  
  

  The laser marking machine can mark all kinds of text, product number, serial number, production date, bar code, two-dimensional code and so on, and the product number, sequence number, date and time can automatically jump number.

  The graphics and characters of the laser marking are fine, clear, and can not be corrected or erased. It is convenient for the quality of products and channels to be tracked, and it is more effective in anti-counterfeiting, blocking and avoiding the sale of outdated products. The process is fast, noise free and pollution-free. Laser beam is easy to guide, and is easy to combine with NC system for machining complex and shaped parts.

  
  

  Laser processing has many unique advantages：

  It can be used for a variety of metal and non-metal processing, especially materials with high hardness and high melting point. Because the tools used in processing are laser beams, no "tool" wear, and the cutting force has no effect on the workpiece during processing; the energy injection speed is high, the thermal deformation of the workpiece is very small, and the heat effect on the material is affected. The area is small; in particular, the sealing parts can be processed through transparent medium.

• Ask：Ten principles of the operation of a laser marking machine

  Answer：

  Ten principles of the operation of a laser marking machine

  In the operation of semiconductor laser marking machine, the staff should pay attention to the following ten principles:

  1. Wear appropriate laser goggles. Laser die welding machine

  2. no use without permission, only those who have received professional training.

  3. laser is applied in the controllable area and warning signs are added.

  4. try to seal the beam around to prevent the leakage of laser light.

  5. avoid using eyes directly to see laser light.

  6. the body avoids the entry into the beam and the range of its reflection.

  7. there should be no unnecessary reflectors (such as metal materials) beside the working objects.

  8. the processing object is properly covered.

  9. laser body as far as possible not erected at the disadvantage of human eye height.

  10. pay attention to ventilation or exhaust state in laser processing environment.

• Ask：What are the processing methods of the tapping machine and the tapping machine

  Answer：

  Tooth attack is widely used in machining mechanical parts. How to choose a good tapping machine is particularly important. Below I give you the tapping, the handling of tapping machines for each person to understand their own working principle according to the better equipment and equipment of their own choice.

  
  

  
  

  There are 3 common tapping machines:

  
  

  A pair of gears, connecting axes, and connecting axes. So the rotating and moving tools can spiral.

  
  

  The spindle is connected with the thread gauge. On the nut gage, move back. Because the nut is fixed in the power head body, the nut is not rotated. So when adjusting the rotation of the teeth, it will drive the spindle and rotate the teeth marks according to the track.

  
  

  Servo tapping: no need to use thread gauge. Servo motors are used for each feed of the shaft and the rotating shaft. Motor control system, spindle speed and feed rate, thus forming tracks along the thread spindle rotation.

  
  

  The solution and suggestion of deep hole drilling tapping machine is because titanium parts are difficult to process, so we should give full consideration to cutting parameters and cutter geometry.

  
  

  The cutting speed of titanium alloy has high elasticity and deformation rate. Therefore, the cutting speed of pneumatic tapping machine is relatively small. In the processing of titanium alloy parts, pneumatic tapping machine is circular cutting speed recommended 10 to 14 inches per minute. We do not recommend the use of smaller speeds, because this leads to cold hardening. In addition, tool breakage caused by cutting heat should also be paid attention to. Deep hole tapping requires reducing the tap space and the chip space of each slot. Therefore, when the tap is retracted, more iron can be taken, because the chance of tool breakage decreases because of the iron plug. But on the other hand, the tap groove increases the core diameter, so the development intensity is affected. So this will also affect cutting the small front angle to improve the strength of the cutting edge, thereby improving the tool life; and cutting the metal scrap with the big front corner is long. Therefore, in the process of titanium alloy, these two factors need to be considered, and the proper front corner should be chosen. The friction between tool and chip can be reduced at a large angle. So sometimes after the angle is needed, the faucet is 40 degrees. In titanium alloy processing, the angle of tap wear is large, which is beneficial to the chip. In addition, grinding taps and edge grinding are also beneficial to tapping.
