Adjust the cutting process for your production

CYPCUT software has simple user-oriented controls. The implemented functions greatly simplify and optimize the cutting process.

  • FLYCUT technology allows you to determine the shortest and most efficient cutting trajectory enabling fast cutting of round and rectangular holes in sheet metal with thicknesses up to 1 mm. In this case the laser head works without lifting and lowering which ensures high speed of work and saves gas. This mode is suitable if you are manufacturing ventilation systems.

  • Prevents corners from melting and increases the quality of manufactured products due to the laser head looping at each corner and not stopping. The obtained corners are clear and even. RINGCUT function is suitable for working with thicker materials or for cutting products with multiple corners where precision is important, e.g. gears, monograms, souvenirs, etc.

  • Professional optimization of the arrangement of parts on the sheet suitable for the production of promotional products. NESTING function allows to lay out parts on the sheet as efficiently and as close to each other as possible so that there are no gaps. This allows saving material.

  • Allows to precisely determine the position of the sheet in the work area using three reference points. You can only put the material on the work area, specify its dimensions in the program and the machine will do everything itself. You do not need to put the material perfectly on the table.

  • It is used to insert micro-joints into the processing path so that the parts do not land on its side. In this case it is easy to remove the parts after cutting. This saves working head from colliding with parts during operation. This function allows producing small parts for promotional and souvenir products without losing them in the work area.

  • This mode allows to join lines that are close to each other, that is to join them so that the laser head does not cut in the same place. This function will greatly improve performance and reduce the operation time. This function is suitable for mass production, for example, while manufacturing workpieces, promotional and souvenir products, etc.

Metal cutters from Wattsan — forget about repairs and downtime

  • Precise design

    In the process of designing the machine, various tests of static and dynamic loads were carried out to identify the maximum permissible deformations of the table and the bed in order to preserve the correct geometry of the structure. Due to the selected configuration, the maximum load on the table is increased by 800 kg of distributed weight. This allows processing materials up to 15 mm thick, with a 24/7 cutting accuracy of +-0.01 mm ,and ensures the durability of the bed up to 10 years.

    Precise design
  • Machine portal

    Wattsan HARD machines use portals made of aluminum with an extra large cross-section. Aluminum portal with extra large cross-section is a good hardness and rigidity with light weight, as well as resistance against corrosion and oxidative processes. All this guarantees a long term and trouble-free operation.

    Machine portal
  • Robust bed

    Wattsan Hard frames have state-of-the-art design. Their main task is to prevent vibration when working at designed speeds and accelerations. The Wattsan Hard heat-treated steel base with stiffeners has a metal thickness of 15-18 mm, which ensures the "indestructibility" of the frame, service life over 10 years and trouble-free operation.

    Robust bed
  • Protective cabin

    The module with a cabin is designed to protect against reflected radiation and sparks during cutting. The cabin can be installed on any Wattsan metal cutter. And according to safety regulations, the cabin should be installed on machines with an emitter power of 2000 watts or more.

    Protective cabin
  • Triple frame protection

    Refractory tiles are installed for protection of the transverse stiffeners inside the frame from heating and damage. The frame surface is protected by a special graphite and ceramic coating, as well as copper plates to prevent deformation of the bed from the thermal effects of the laser beam.

    Triple frame protection
  • Double protection of the guides

    Wattsan machines are equipped with a special metal protection of the machine corrugated surface to further maintain the cleanliness of the sliding guides, saving time and money for replacing the dust cover.

    Double protection of the guides
  • Loading rollers

    Several ball bearings on the working table make it easier the sheet loading onto the table. The rollers can be mounted on the front, back or side of the machine as desired. The roller is lifted above the cutting table in such a way as to ensure optimal feeding. One of the most important advantages of this feeding system is the prevention of scratches on the material.

    Loading rollers

Firm frame structure of Wattsan machines

During the machine operation inertia of gentry motion is transferred to the frame which is subjected to significant loads. Therefore material and structure of the machine play a significant role in securing the machine against deformation and breakage.

  • In the process of designing the machine, all kinds of tests of static and dynamic loads were carried out to identify the maximum allowable deformations of the table and machine bed in order to maintain the correct geometry of the structure. Due to the selected design configuration, the maximum load on the table is increased by 800 kg of distributed weight. This allows you to process materials up to 15 mm thick, with a cut quality of +-0.01 mm and 24/7 and ensures the durability of the bed up to 10 years.

    Worktable can withstand heavy loads
  • Wattsan frames are designed according to the latest technology, their primary objective is to avoid vibration when operating at design speeds and accelerations. The frame is installed on vibration mounts or is anchored to a 50 cm thick concrete pad.

    No vibrations
  • All frames undergo multi-stage heat treatment within a day which results in less vibration during machine operation. This technology allows to release tension from metal and increase the machine’s service life from 10 years and more.

Ask questions

  • A fiber-optic laser is best suited for cutting metal, but a specially equipped CO2 laser with a high-power laser tube may also be suitable for this purpose. However, it should be borne in mind that the thickness of the metal for cutting with a CO2 laser is limited to 1.5 mm, while a fiber-optic laser is capable of cutting up to 25 mm.

  • The cost of an hour of laser cutting depends not only on the power of the laser machine and the speed of its operation, but also on a number of other factors, such as: the professional skills of the machine operator, the cost of renting a production room, the cost and consumption of electricity, the cost of the material itself, the amount of scrap and downtime of the machine, and much more. In order to unambiguously answer the question about the cost of an hour of laser cutting, it is necessary to take into account all these parameters.

  • A focused laser beam is applied to the metal surface, as a result of which it melts, the molten material is blown out of the cutting zone with the help of an auxiliary gas.

  • The power of the laser emitter depends on the thickness of the material being processed and the desired processing speed. For example, a 1 kW emitter will cut 1 mm thick stainless steel at a speed of 13 m/min, and a 3 kW emitter will cut the same material at a speed of about 35 m/min. Here everything depends on the budget and the expediency of using the maximum possible capacity. Although it can be said that in today's competitive realities it does not make sense to buy a laser machine with a power of less than 1 kW.
