Main features
Based on fiber laser IPG Photonics and gantry coordinate system LC Master provides a high efficient solution for the Medium enterprise.
Laser
LC Master 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 an entirely sealed body. This excludes any contamination and allows our customers to cut down costs on the 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 lasers 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 a metal engraving.
Beam delivery
A beam is delivered by a fiber-optic path without mirrors. Thus an amount of necessary consumables is minimized. The fiber system is absolutely reliable; its lifetime can be compared to the laser itself.
Arrangement and design
We pay special attention to the arrangement and design of the equipment. All parts (a laser unit, cooling unit, automation cabinet, etc.) are combined in one complex which leads to saving valuable meters of production facilities, perfect organizing of production operations and increasing reliability of the laser cutting machine. The separate working table and coordinate system, however, allows for cutting shaped and round tubes, bended or welded structures, and working out other non-standard solutions. Edgy design outlines the whole production process.
Workpiece loading
An opportunity to install power-operated units on three sides of the cutting table is the main feature of LC Master. It enables to organize simple and convenient loading of tubes and rolled material. LC Master can be optionally equipped with a shuttle table which facilitates operation and greatly improves efficiency. The shuttle table includes two pallets which are alternately moved to the cutting area. It enables to provide loading / unloading operations on the running machine.
Machine bed
The machine bed is an all-welded structure with subsequent machining. It combines a high accuracy of production, rigidity, reliability and long life. To withstand high dynamic loads the structure is additionally made heavier.
Gears and drives
Ensuring movement of the coordinate system mechanical components and drives are the crucial parts of the machine. Laser cutting machine LC Master is equipped with high power and speed maintenance-free linear drives.
Lubrication system
Moving parts of any machine require regular lubrication; they are often covered with protective casings 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 about the time to lubricate machine parts. Dismantling of 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.
Cooling system
LC Master is equipped with the water / air cooling system providing a perfect solution for machine cooling and reducing expenses for water consumption.
Gas supply system
It’s crucial to ensure that technical gas blowing of the cutting area maintains the constant pressure during metal cutting. We offer a perfect solution – the pneumatic system of LC FO Master which ensures a pressure of 20 atm. This allows for cutting nonferrous metals and reaching the highest quality. LC FO Master can be optionally equipped with an automatic gas console with CNC integrated interface which provides a remote control of gas inlets and a gas pressure, and monitors current system status. The console controls switching of a cutting gas type and sets its pressure automatically if materials are selected from the Library.
UniCut software
User-friendly and functional software plays a crucial role for laser cutting operations. It allows an operator to control the machine in the most effective way, prepare and upload cutting programs, as well as provide the module’s settings.

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.
