Main features
IPG laser
Kilowatt-class fiber lasers applied in LC 3015 Ultra represent some undeniable advantages compared to other types of lasers. They do not require any complicated maintenance: supervision of skilled personnel or consumables are no longer needed. The fiber laser is the most reliable among the existing ones. The operating lifetime exceeds a decade due to the entirely sealed body that contains the dryer and enables operation in the harsh industrial environment.
Beam delivery
A beam is delivered by a fiber-optic path without mirrors. The fiber system is absolutely dependable; its lifetime can be compared to the laser itself.
Optical laser cutter LH-110
LH-110 takes the automation processes to the next level. The built-in lens drive enables to adjust the focus length automatically making settings of the cuttings modes a lot easier. The adjustment occurs automatically when an operator selects a material from the UniCut library.
The cutter is equipped with the cartridge system of lens and protective glass replacement enabling to reduce the service time and protect against dust penetration to the laser body.
Gear and drive
LC 3015 Ultra is equipped with the high power linear drive and state-of-the-art digital data bus. These solutions enable to reach unparalleled free movement speed and acceleration leading to high efficiency cutting even of the most complicated contours.
Lubrication system
The machine is equipped with the automatic lubrication system: it lubricates all main parts as soon as the maintenance time comes. The machine is being lubricated in operation/running and do not require operator’s supervision or actions.
Zoned smoke exhaust system
Our machine is equipped with the zoned smoke exhaust system. Only the area where the cutter is currently working is connected to the ventilation system. This solution makes it possible to exhaust smoke with extreme efficiency and, at the same time, to use less powerful ventilation system.
Cooling system
The machine is equipped with water / air cooling system providing efficient cooling and water cost reduction.
Gas console
Blowing of the working area with an assist gas is crucial during metal cutting. LC 3015 Ultra is equipped with 4-gas console with a CNC integrated interface. The console automatically switches the cutting gas and sets its pressure from the UniCut Library.
Nozzle cleaning and calibration system
Checking the condition of the laser head nozzle is highly important to maintain high quality cut. Cutting waste may adhere to the nozzle surface, disrupt the operation of the capacity sensor, and lead to a collision with the metal surface. Laser cutting machine LC Ultra features a special function – automatic nozzle cleaning. The cleaning initiates after a certain number of piercings. The optical head moves towards the cleaning area, the brush cleans the nozzle, and then it returns to the initial position.

Control console UM-103
The control console is a separate dust-proof console equipped with an LCD to display operating data. All controls and LEDs are located on the front panel. Such layout allows an operator to react to potential errors within the shortest time, prevent any serious problems and work in the convenient environment.
To provide additional comfort the console has special drawers to store consumables or tools, and a holder for papers. CNC console is equipped with two USB ports to connect flash drives or download drawings and programs. A LAN port, which enables to integrate the machine with the general manufacturing system, is located on the back panel.
Wireless remote control
Wireless remote control allows an operator to do the most common operations from any place: start and stop, back travel along the contour, increasing / decreasing the focus length, upload speed change, machine and workpiece zero point, start and stop of automatic pallet change.
UniCut software
User-friendly UniCut software is a proprietary development of our company. To simplify and optimize cutting process UniCut provides the special functions such as pause, back move along the contour, quick transition to any piercing, quick change of piercing point, cutting can be initiated from any point of contour, etc.
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 cutting process. 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 the zero speed (at the moment of stop at the corner) output power equals to minimum power configured in the settings which prevents a corner’s burnout.
Library of materials
UniCut software includes the Library of materials, where a user can find recommended settings for particular materials or use a special 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.
Maintenance timers
Software maintenance timers help to provide technical maintenance on schedule indicating time to replace consumables. The software automatically calculates working hours for the machine units and notifies an operator about the required service.
Production statistics
UniCut software automatically calculates time for workpiece processing, beneficial use of materials, number of parts. Received data significantly simplify cost calculations, e.g., calculations for third-party orders, costing production and waste.
Remote diagnostics
Remote diagnostics of system malfunction (through the Internet) makes it possible to reduce downtime of the machine and cut down off-site expenses concerned with wrong settings of the equipment.
Operator’s log
Working objectives can be assigned and controlled remotely from the operator’s workplace reducing paperwork and setting objectives through the network. That helps to organize working process more efficiently because systematization (materials, priority, product) is done automatically in this case.
Intuitive and user-friendly software
Simple and intuitive UniCut software saves time of staff training: a mid-level specialist can be quickly taught some basic operations with the machine. The work of mid-level specialist will cost less than a highly-skilled professional resulting in the lower product cost.

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.
Focus length control system FoCut also allows for processing non-metallic materials.
