Welcome to my blog. Please drop me a line.

I am a freshman on blog. Here I come to show my story. All what I have already got, all what I have already lost.

Why the CNC plasma cutting machine can not cut through the steel?

Why the CNC plasma cutting machine can not cut through the steel? 
First to check if it the problem of the machine or the plasma power supply.

The common problems of CNC plasma cutting machine are the following factors. No arc CNC plasma 
cutting machine; the arc can not cut through the plate, or the arc easy broken through cutting etc.

When face the problem of no arc, first we need to check the electrode and nozzle of the cutting gun.
 If it is damaged or replaced bad position. If it is in good condition, we have to check whether the 
plasma power ventilation or air supply bad. We can judge the power supply problems or CNC cutting
 machine problem through a short connecting power -the arc.

The plate can not be cut through by arc. Why? 1 reasons, a small current of CNC plasma power 
machine can not cut the thick plate, 2, Grounding wires and cutting plate is not connected well. 3,
 The air pressure is too small. 4, the gas for the plasma power supply owns high water content. 5, 
The plasma cutting nozzle is too small.

Steel Laser Cutting Machine and Co2 Laser Tube

Laser processing is a kind of thermal processing. And in the thermal process it will produce heat which will cause the deformation of sheet. Within a small range of excessive heat concentration can produce the material combustion. All of these have a detrimental effect on the material.

According to different materials, different cutting requirements, using different cutting auxiliary gas. Its purpose is to get the best cutting quality.

Cutting boards such as stainless steel or aluminum, generally using nitrogen gas as auxiliary, the cooling and protection. The carbon steel cutting with oxygen, the cooling and accelerate the combustion speed cutting purpose.

The types and functions of gas are commonly used to laser cutting machine:

1, air: ① as cutting gas used as cooling cutting head and used as a light path (internal dust protection lens extension lens use time)

2, general oxygen: as the gas cutting carbon steel (oxidizing) purity 99.5%

3, pure nitrogen: as the gas cutting stainless steel (cooling) purity 99.9% (cutting carbon steel at 3/4)

4, high purity nitrogen: use as gas, laser Purity: 99.999%

5, high pure helium: as the use gas, laser Purity: 99.999%

6, high pure carbon dioxide: as the use gas, laser Purity: 99.999%

Why Spindle Motor of CNC Router become very hot in the beginning of work?

Why Spindle Motor of CNC Router become very hot in the beginning of work?

First to replace the bearings, iit is still hotplease check out one by one the following points.

1, To check the water cooling circulating well. If the temperature of the water is beyond 20 degrees,you can add ice in the water. While the air-cooled spindle possible blocked by the spindle blades.

2, To check the coil. Bearing bread produce a particular noise or the spindle refuses to move.

3, In fact, a bad bearings with bad-quality high-temperature lubricants will not works.

4, To check the speed of the spindle motor work is not close to the rated speed, while it heated by reaching its limit.

5, To check the if the CNC Router electricity resourceand the output frequency and current compliance required by the machine.

6, To check the spindle work. And make the spindle feeding less each step. To run the spindle feeding too hard is also a reason being heated.

Operation Training of CNC Router

Operation Training of CNC Router

Following steps is CNC Router operation training .

1, The training must start from the theoretical training. The operator should read the manual  before operating It helps the operator mastering the operation and make progress with the training engineers.

2, Tool selection and installation applications. The operator should pay attention to the commonly used tools. He need to learn how to adjust the spindle motor speed and the gantry movement speed. When cutting hard materials, he master the cutting speed to prevent the cutting tools from breaking.

3, The characteristics of the processing material. The operator must be familiar with the various materials, and analysis the different thickness and different sizes as well as different hardness. So that find the most efficient operating parameters for processing the material to make a perfect sample.

4, The training of the software come after the above training. Software training mainly refer to the user applications lines. If the user promote the new products in the future, he can do their research based on the manual.
Software training includes: a variety of publishing software, all types of operations and the path generated and how to quickly identify the wrong path.

5, The training engineer estimate operator's machine working environment and endorsed the operational safety precautions.

6, Finally the training engineer will notice the various cautions and CNC router maintenance .

LASER. World of Photonics China Shanghai 2013

LASER. World of Photonics China Shanghai

Laser World of Photonics China Shanghai start on 19th-21th in New International Expo Centre. It provides an opportunity to gain insight into the lastest technologies and applications in the complete range of electronics and to meet international experts.

As the fiber become hot in laser physics research, it is supposed to take full place of solid-laser to be a new laser generation.

COMEID fiber laser marking machine is develofed in cooperation with German and Britain laser companies by using the cutting edge technologies.

The advantage is as follows:

It adopt the imported laser generator and scanner guarantee the high efficiency of the electron-light transformation. To make less of power consumption while work high speed with less of total power.

Fiber is much smaller size than glass tube laser or solid laser. It represents high quality fine lined laser engraving and marking. So that it fit for joining an industrial production line.

The most adorable is that there is no consumption parts, no maintenance. And it air cooling itself while working in any circumstances.
