Main features

Laser

LC Professional M2 fiber lasers represent some undeniable advantages compared to other types of lasers.

First of all, the lasers do not require any maintenance as they are located in the entirely sealed body. This excludes any contamination and allows our customers to cut down costs on high-skilled service staff and consumables.

Secondly, fiber lasers are the most reliable among the existing ones. Their operating lifetime exceeds a decade.

Finally, an output emission of fiber laser has a high quality and stabile beam parameters.

In addition to the above, the laser is ideal for cutting highly-reflecting materials, such as latten, aluminium, copper, galvanized and stainless steel, and making metal engraving.

Beam delivery

A beam is delivered by a fiber-optic path without mirrors minimizing an amount of necessary consumables. The fiber system is absolutely reliable; its lifetime can be compared to the laser itself.

Arrangement and design

Unimach® pays special attention to the arrangement and design of the equipment. To provide additional comfort all external connections are carried out from one side. The main elements are covered with the protective casings preventing the equipment from dust and shock impacts. Edgy industrial design outlines the whole production process.

Metal sheet loading

Sheet loading is carried out using a pull-out pallet. It can be easily moved out of the cutting area providing machine-safe and comfortable loading. The shuttle table for LC Professional M2 which makes it possible to increase production capacity significantly and simplify working with the machine is at option. The shuttle table system alternately moves two pallets into the cutting area. This ensures loading and unloading of workpieces non-stop.

Machine bed

The machine bed is an all-welded heat-treated structure with subsequent machining. The bed of LC Professional M2 combines high production accuracy, rigidity, reliability and long life. To withstand high dynamic loads the structure is additionally made heavier.

Gear and drives

Ensuring movement of the coordinate system mechanical components and drives are the crucial parts of the machine tool. Laser cutting machine LC Professional M2 is equipped with high power and speed maintenance-free linear drives. Their application minimizes a number of mechanical components in the coordinate system resulting in increased durability and reliability.

Lubrication system

Moving parts of any machine need regular lubrication; they are often covered with protective casings or bellows at high quality equipment which is, however, limiting the access. To work this issue out Unimach® has equipped the machines with the centralized lubrication system and maintenance timer. A CNC stand notifies an operator if it is the time to lubricate machine parts. Time-consuming dismantling of the protective casings is not required, because an operator simply needs to supply a lubricant from the central control panel and confirm it by entering the service password.

Smoke exhaust system

Our machine is equipped with a zoned smoke exhaust system. The zones are switched over automatically, i.e. only the area where the cutter is working at the moment is connected to the ventilating system. This solution makes it possible to use less productive ventilating system and to exhaust smoke with extreme efficiency, as well as save the electricity.

Cooling system

LC Professional M2 uses water / air cooling system (chiller) providing efficient cooling and cutting down water expenses.

Gas supply system

It’s crucial to ensure that gas blowing of the cutting area maintains the constant pressure during metal cutting. We offer a perfect solution – the pneumatic system of LC Professional M2 which operates with the maximum pressure of 25 atm. Such pressure is ideal for cutting nonferrous metals and reaching the high quality of cut edge. The systems which use maximum pressure of 10 atm significantly limit the application range of laser machines. LC Professional M2 can be optionally equipped with an automatic gas console with a CNC integrated interface which provides a remote control of gas inlets and gas pressure in the cutting area, and monitors current system status. The console automatically switches the cutting gas and sets its pressure from the Library without Operator's supervision.

Laser optical head LH-110

• Max pressure 25 atm
• Pneumatic system removes molten metal while piercing
• Forced nozzle cooling at cutting non-ferrous metals
• Nozzle temperature control
• Video monitoring of nozzle and laser center adjustment
• Quick (cartridge) change of protective glass
• Quick (cartridge) change of focus lens
• Focus lens drive is controlled from the CNC in order to provide high-quality metal piercing and automatic change of focus length if the type or thickness of material is changed. All focus lens adjustments are carried out using CNC.
• Screws for transverse nozzle movement. While being adjusted the lens remains fixed excluding any laser thermal damage and expanding its life time.

Control operations from your workplace using one program

All control interfaces of the machine units are integrated in one program. All cutting machine modules can be controlled from one workplace to provide additional comfort.

Individual settings for laser piercing, engraving and cutting

Laser piercing, engraving and cutting modes can be set individually before the start of cutting cycle. There’s no need to stop the process in order to change or enter the new settings. Switching among the modes occurs automatically leading to higher production capacity of the cutting machine.

Laser power can be controlled depending on the speed

To reach higher quality of sharp and right angles laser power can be controlled automatically depending on the speed of the optical head. At zero speed (at the moment of stop at the corner) output power equals to minimum power configured in the settings which prevents the corner from a burnout.

Library of materials

UniCut software includes the Library of materials, where a user can find recommended settings for particular materials combined with the function to create new ones.

Automatic program creation

UniCut software can help you to create a cutting program quickly and intuitively, in a few clicks. The program automatically detects nested contours and calculates the most optimal travels. This function is useful for small enterprises that are dealing both with small batches and a wide range of products.

User-friendly interface

Provide the settings quickly using our user-friendly graphic interface. Graphic data is easier to percept than endless lines of digits, it saves your time and makes workplace’s atmosphere more comfortable.

Focus length control system FoCut

Automatic tracking system Focut of our machines controls a stabile position of an optical head with precision of 0.1 mm within the wide range of heights. It ensures precise cutting both on the workpiece edge and highly deformed metal sheet. Learn more

The system includes the following capabilities:

Jump up piercing. At the moment of piercing an optical head is uplifted to the specified height preventing the nozzle from contamination by the melted metal. Then the further cutting is carried out from the specified focus length. This method helps to use the consumables - a nozzle and protective glass - efficiently and avoid possible errors or malfunction.

Fly cutting (without stopping to pierce the material). This method crucially reduces the time for processing thin sheets as the machine cuts all contours which are located along one line (and not each separate pattern). An optical head moves all over the workpiece cutting the contours of the relevant area. This function is perfect for cutting perforated grilles.

Pre-heating of the cutting area. Cutting thick material requires pre-heating. An optical head uplifts at the height set by an operator and heats the cutting area; then the optical head goes down and cuts the material.

Shortened height. While moving from one piercing point to another an optical head is not uplifted to the maximum height; it is lifted at the shortened height, therefore saving time and increasing the efficiency of the machine.

Automatic calibration of the optical head. Automatic calibration system ensures calibration at every piercing point. This function maintains high quality even when cutting the strongly deformed metal.

Graph display of dynamic and operating parameters. A graph is a convenient, simple and time-saving way to estimate operation of tracking system and detect errors.

FoCut system also allows for efficient cutting of non-ferrous metals.
