Laser cutting and milling

Technology cutting and cutting of materials, using high power lasers and is generally used in industrial production lines. A focused laser beam is usually controlled by a computer, provides a high concentration of energy and can cut virtually any material, regardless of their thermophysical properties. In the process of cutting, under the influence of the laser beam melts the material being cut section, ignited, evaporates or is blown by a gas jet. It is possible to obtain narrow cuts with minimal heat affected zone.

Laser cutting distinguished by the absence of mechanical effects on the material being processed, there are minimal deformation, as time in the cutting process, as well as the residual after complete cooling. As a result, laser cutting, even legkodeformiruemyh and non-rigid parts and components, can be performed with a high degree of accuracy. Due to high power laser radiation is provided by high-performance process, combined with high quality cut surface. Easy and relatively easy control of laser light allows a laser to cut the complex plane and three-dimensional contour of the parts and pieces with a high degree of automation of the process.


Laser cutting of metals is used process plants based on solid-state, fiber lasers and gas CO2-lasers operating both in continuous and in pulse-periodic regimes of radiation. Industrial use of gas-laser cutting is increasing every year, but this process can not completely replace traditional methods of separation of metals. In comparison with many of the plants used in the production cost of laser equipment for cutting is still quite high, although recently there has been a tendency to decrease. In this regard, the process of laser cutting becomes effective only when justified and reasonable choice of applications where the use of traditional methods of time-consuming or even impossible.

Laser cutting is done by burning a cross-cutting of sheet metal by laser beam. This technology has some obvious advantages over many other methods of cutting:

  • No mechanical contact can handle fragile or deformed materials;
  • Treatment of materials amenable to solid alloys;
  • Optional high-speed cutting of thin sheet steel;
  • With the release of small quantities of products appropriate to hold the laser cutting of the material than to produce this expensive molds, or molds;
  • For automatic cutting of material is sufficient to prepare a picture file in any drawing program and transfer the file to your computer setup that will stand the error in very small quantities;

Milling (Milling) - treatment of materials by cutting with cutters.
Rotary cutter does, and harvesting - mainly translational motion, usually in the direction perpendicular to the axis of rotation of cutter.

Classification of Milling

Classification of milling can occur in different ways, depending on whether they want to highlight the most significant:

  • Depending on the location of the machine spindle and the convenience of securing the workpiece - vertical, horizontal. In production use more universal milling machines to allow horizontal and vertical milling, and milling at different angles to different tools.
  • Depending on the type of tool (mill) - end-, face, peripheral, mold, etc.
    1. End-milling - slots, grooves, undercuts, wells (through the slots), pockets (slots out of which more than one surface), windows (grooves that go on only one surface).
    2. Two. Face milling - milling large surfaces.
    3. Three. Shaped milling - milling profiles. Examples of profile surfaces - gears, worms, moldings, window frames.
    4. There are also specialized cutters designed for cutting (disc cutters).
  • Depending on the direction of rotation of cutter relative to the direction of its movement (or movement blanks) - obiter "on a tooth" when the milling machine "dominates" the workpiece to a very clean surface, but also a great danger of tear-out when a large piece of material removal, and a counter "to the tooth "when the movement is towards the cutting edge of the workpiece. Surface is worse, but it increases productivity. In practice, the use of both types of milling, "the tooth" in the preliminary (draft) and "a tooth" is the final (finishing) treatment.
