Laser cutting

Laser cutting is a technique used to cut sheet metal parts characterized in that the energy source is a laser that concentrates light on the work surface.

The two most common types of industrial laser is carbon dioxide (CO2) and yttrium aluminum garnet doped with neodymium (Nd: YAG). A CO2 laser uses a gaseous medium to produce laser action while the Nd: YAG uses a crystalline material. The CO2 laser is commercially available in powers up to 6 kW and Nd: YAG systems are available in up to 6kW.

If done with mechanized equipment, laser cuts provide highly reproducible results with narrow widths of slots, minimal heat affected zones and virtually no distortion. The process is flexible, easy to automate and provides high cutting speeds with good quality, since the laser is able to operate very complex cutting profiles and with very small radii of curvature. Moreover, it is a clean technology, it does not pollute or use chemicals. Equipment costs are high but are decreasing as the technology is less expensive resonators.

3D printing is a group of manufacturing technologies by addition where a three dimensional object is created by superimposing successive layers of material. Las 3D printers are generally faster, cheaper and easier to use than other manufacturing technologies addition, although like any industrial process, shall be subject to a compromise between their purchase price and tolerance in measurements of the objects produced. 3D printers offer product developers the ability to print parts and assemblies made of different materials with different physical and mechanical properties, often with a simple assembly process. Advanced 3D printing technologies, may even offer models that can serve as product prototypes.

Since 2003 there has been strong growth in the sale of 3D printers. Conversely, the cost thereof is reduced. This technology also finds use in fields such as jewelry, footwear, industrial design, architecture, engineering and construction, automotive and aerospace, medical industries, education, geographic information systems, civil engineering and many others.

A motor grader is a construction machine that has a long sheet metal used to level land, also has rippers for hard surfaces, which can be placed in front, in the middle of the front axle and the blade or the back, calling in this If ripper.

Generally they have three axes: the cab and engine are located on the back, on the two tractors axes and the third axis is located in the front of the machine, the dozer blade between the front axle being located, and two rear axles. In some countries such as Finland, most motor graders are equipped with a second blade, located in front of the front axle.

The main purpose of the bulldozer is leveling land, and refine slopes. One of the characteristics which give great versatility of this machine is that it is capable of refining slopes with different inclinations. The work of the bulldozer usually complement the previously performed by other construction machinery such as excavators and bulldozers.

The most common work of motor grader are:

• Paving a row of material discharged by truck and subsequent leveling.
• Refining esplanades
• Reprofiling of slopes.
• Excavation and conservation reprofiling of ditches on earth.
• Service and maintenance.

Components motor grader

• 1.     Foot of moldboard:
  It is the foremost end of the blade in relation to the direction of travel. It is generally the end which is closest to the front wheels of the machine.
  2.     Slip the blade moldboard:
  It is the rearmost blade relative to the running direction end. It is generally the end which is closest to the wheels tandem machine.
  3.     Twist of the circle:
  It Allows 360 degree rotation of the circle and moldboard to adjust the angle of the blade to the material or application features. The angle of the blade is very important because it allows the material to roll along it, increasing productivity Grader.
  Normally, a bulldozer moves the material back and forth in the area being leveled, instead of pushing it forward. This displacement of material by rolling from side to side of the sheet to its side discharge, requires less engine power if I had to be pushed. To get this rolling action must simultaneously make use of more of the possibilities of the machine, as the rotation of the circle, the lateral displacement of the drawbar and tilt moldboard. (It is available as an option of an adjustable slip clutch to protect the circle drive the high horizontal forces occurring in applications.

Steel 1050

Thanks to the good penetration temple that has this steel is suitable for machine parts that must withstand high longitudinal and transverse forces, but continuous impacts.

Boron steel

Boron does increase the hardenability when the steel is fully deoxidized. A small amount of boron, (0.001%) have a marked effect on the hardening of steel, as it also combines with carbon to form carbides that give the steel hard coating characteristics.

Quenching and tempering:

By giving carbon steel quenching and tempering very good characteristics are achieved when the profile is slim. In a well-tempered steel or carbon tempering, the value of yield strength tends to become 75% of the breaking load.

5.   Frame:

The frame or chassis is the metallic element that supports all the mechanisms that carry a bulldozer.

6.   Front Axle

The front wheels support a long beam bridge which hangs moldboard. In some types of machines the beam is attached by a pivot to the rear frame to permit rotation in a small circle, better handling, and allows the frame advance angle relative to the direction of travel while maintaining the parallel wheels. In other union it is rigid and steering control is only possible in the front axle. The design allows the wheels: (a) is inclined about 18 ° to each side of the vertical to resist lateral thrust when, for example, works moldboard inclined position, and (b) work at different levels to shape gutters, cambers, and other similar tasks. The combination of both devices enables management to control without excessive concentration by the driver, freeing your attention for moldboard.
