The Differences between CNC Laser Cutting Machine and CNC Punching Machine

The CNC equipment is now the mainstream for the processing equipment with more accurate and simple intelligent work style, so more and more customers choose them. The most widely used in CNC equipments are CNC laser cutting machine and CNC punching machine. These two kinds of equipment are indispensable in metal processing. What are the differences between the two kinds of CNC equipment?

The CNC fiber laser cutting machine is used to melt and vaporize the stainless steel by using a laser beam to illuminate the surface of the steel plate. The laser source generally adopts carbon dioxide laser beam or fiber optic laser beam with work power 500 ~ 2500 watts. The power is lower than the power required for many household electric heating. However, through lenses and mirrors, the laser beam is concentrated in very small areas. The high concentration of energy is capable of rapid local heating and evaporation of stainless steel. In addition, because the energy is very concentrated, only a small amount of heat is transferred to other parts of the rolled steel. The laser can cut the blank of complex shape very accurately, and the cutted blanks are not necessary for further processing.

The CNC punching machine can be used for processing of all kinds of metal sheet parts. It can automatically complete various complex and shallow tensile forming processes at one time. Through simple die combination, a large amount of mould cost is saved compared with traditional stamping.

Comparison between CNC laser cutting machine and CNC punching machine

(1) CNC laser cutting machine can be used for thin plate and thick plate processing, while the CNC punching machine mainly focuses on sheet processing.
(2) CNC laser cutting machine can process all kinds of complicated graphics, which can be completed without the limitation of complexity. CNC punching machine can only process simpler graphics.
(3) CNC laser cutting machine is not necessary to open mold, and it is more cost-effective than the CNC punching machine.
(4) the automatic tracking system of CNC laser cutting machine can be processed on the surface, while CNC punching machine has high limitation.
(5) CNC laser cutting machine has high machining precision. It is suitable for mass production.

Fiber Laser Cutting Machine

Nowadays laser cutting machine is more and more widely used, as it is with high speed, high precision and automation. It can save manpower and improve production efficiency.  The laser is shot from laser generator, through optical system, focus to high power and density laser beam. The beam shoots on surface of workpiece and makes it reach melting point or boiling point, at the same time, the high pressure gas which is on the same axis with laser beam blow the melting or pneumatolytic metal away. That is the basic reason of laser cutting. According to the laser generator, there are two types – CO2 type & fiber type. The frequency of the CO2 laser requires higher wattage of lasers to penetrate through metals. CO2 laser systems are best suited to cutting wood, acrylic, plastic, and fabric.  Fiber laser cutting machine  is much more energy saving. In the situation that reaches same performance, whole fiber cutting can save around 70% energy than CO2 type. The wattage can range from 50

How to Adjust the Clearance of Upper and Lower Blades of Hydraulic Guillotine

To many customers, they can easy to get how to adjust the clearance of upper and lower blades of small model  hydraulic guillotine shearing machines . How every, it's do hard for them to adjustment big models like QC11Y-40*2500 mm or QC11Y-40*3200mm. It is an important factor that affects the cutting quality and prolongs the service life of the blade. The correct adjustment of the blade thickness depends on the shear plate thickness. The machine tool converts the blade gap value to the plate material value directly on the gap dial. The clearance between the upper and lower blades of the shear should be the same throughout the entire length. This shear shall be equipped with a supplementary tool holder on the worktable to be used as a micro adjustment of the uniformity of the gap between the upper and lower blades. The minimum clearance before adjustment is 0.05 mm at the factory. The user should not change easily during normal use. After the blade is used for a certain period of
