The world's largest laser 3D printer was born in Dalian
The author learned yesterday from the Municipal Economic Commission, Dalian Polytechnic University and Dalian excellent Lite Technology Development Co., Ltd. jointly developed the largest processing size of 1.8 meters of laser 3D printer in the city into the commissioning phase. This is the world's largest laser 3D printer, can produce large industrial samples and the structure of the complex casting mold. Thanks to its unique "contour line scanning" technology, it offers 35% shorter processing time and 40% lower manufacturing costs than other laser 3D printers. 3D printing is the world's most popular technology, it completely subverts the traditional industrial processing methods, known as the "third industrial revolution" pioneer. It is reported that the current small desktop 3D printer has been commercialized in Europe and the United States, but in the manufacture of large industrial components, 3D printing a long time, forming expensive materials, physical deformation of large size parts and other issues have been difficult to solve. Professor Yao Shan of Dalian University of Technology and his team, after more than 10 years, solved countless size problems and finally realized a major breakthrough in this field. Professor Yao Shan told the author, the general 3D printing is in accordance with the planned good graphics data, through the "point - line - surface - body" gradually accumulate supplies final parts. And they developed a laser 3D printer simply print the outline of each layer of the parts, so that the coating of the sand on the contour line carbide resin failure, and then follow the conventional method in the furnace at 180 ℃ will print the sand heat curing and post-processing Peel off, you can get the prototype or mold. The processing time of this printing method is proportional to the surface area of ​​the part, while the processing time of the traditional 3D printing technology is proportional to the volume of the part, which can greatly improve the printing efficiency, and the printing speed can reach 5 to 15 times of the general 3D. The use of materials for industrial coating sand, less than a thousand dollars per ton. Significantly increased efficiency, cost doubled. At present, this method of laser 3D printing based on "contour failure" has obtained two national invention patents.
The 1 boom drilling rig is the main drilling equipment in the underground hard rock mine.

Manipulator drilling rig with high level of automation and computerization is not very attractive to mine.
The mine hopes to use the trolley with compact structure, flexible movement, high reliability, high efficiency and high accuracy.
Small enough to enter the shaft through a small section
Maneuverable and flexible enough to walk in winding and inclined passages
The versatility can be used to drill hole, bolt hole and cut hole in all directions.
In recent years, several major rock drilling equipment manufacturers in the world, in order to meet the requirements of mechanized mining of thin ore bodies, have successively developed a variety of small rock drills with high power, which can be used to complete the rock drilling operations that could only be completed by pneumatic drill, so as to significantly improve the efficiency of rock drilling and reduce ore dilution rate.
Hydraulic drilling jumbo is mainly used for tunneling construction in metal mine and other underground engineering. One drilling boom, advanced hydraulic rock drilling system and anti-jamming mechanism ensure the jumbo rapid drilling speed and high efficiency. This jumbo features of great mobility, short turning radius and strong gradeability, thus can improve working environment and get efficiency, quality development.
Robust universal drilling boom creates ideal face drilling coverage. Automatic parallelism and 360 degree roll-over enable easy, fast and accurate positioning for face drilling, sideway drilling and bolt hole drilling.
The layout of components provides excellent vision for the operator in drilling and travelling.Powerful and well balanced 4-wheel drive chassis allows the rig to move through limited space and tough terrain in the mines.
Duo-circuit service brake and enclosed multi-disc parking/ emergency brake ensure safety in tramming and on ramp slope.
Field proven high frequency hydraulic drifter delivers high performance. Trapezoid shaped percussion piston optimizes shock wave transfer efficiency, enhancing penetration and decrease drilling consumables costs.
Comfortable operator station provides safe working condition. Many automatic features simplified the drilling control and helps the miners to concentrate on fast and accurate drilling.
All service points are easily accessible, which simplifies daily routine maintenance for this 1 boom drilling rig in rock ore quarry and underground tunnel drilling blasting DTH purpose.
