2 Laser Cutting Head Laser cutting head is one of the most important components in laser cutting machines. Traditional cutting head consists of only focus lens and cutting nozzle which does not have auto focus function. In wide range laser cutting machines, different processing parts have slightly different height that causes the material deviated from actual focal length. As a result variation of focused beam spot, power density and cutting position will cause laser cutting quality inconsistent and difficult to meet the requirement. Therefore a quality laser cutting head is very important as the height can be adjusted whenever processing any material at different height using any cutting method. The distance between cutting nozzle and workpiece is one of the factors affected cutting speed and quality. Beside selecting suitable nozzle and air pressure parameter according to cutting situation, the distance between nozzle and workipiece should also increase or decrease base on workpiece thickness. To ensure high quality cutting the nozzle during cutting process must always be maintained stability at the same height, especially on thin, textured surface, inconsistent flatness workpiece or even limited cutting environment. It is impossible to adjust the height manually during cutting process as human reaction is slow while cutting speed is very fast. To solve manually adjustment instability, a height adjustment follower is necessary. With the follower installed no matter how thick the workpiece is, the height will always be the same. According to market requirement we developed self-floating auto focus laser cutting head. It uses the capacitive sensing and automated servo system to ensure the cutting process always in focus to have a consistent, clean and no glitch cutting result. With stepper motor, ball screw driver, advanced multifocusing system and high quality optical device, this enable the cutting head to keep the distance with workpiece in stable and reliable condition in long term. It is an essential component for laser cutting machine in order to obtain the optimum cutting quality. sales@sintecoptronics.com 2

23 STC2 Nd:YAG Laser Cutting Head We supply the laser cutting heads with auto-focusing function and you can easily cut uneven surface metals for Nd:YAG laser cutting applications. Laser cutting head is one of most important parts of laser cutting machines. The traditional cutting head only includes focusing lens and nozzle and does not have auto-focus function. If there is no auto-focus, the spacing between the focus lens and workpiece will not be same, which results in different focused beam diameters and then different power densities at different positions. Thus the cutting quality may be different at the positions. Based on the requirements from the market, we have developed self-floating laser cutting heads. By using capacitive sensor and auto motor moving system, the spacing between the focus lens and workpiece will be kept same at any position of the cutting field. The response time is millisecond range only and the system is stable and reliable. There are following main features of our cutting heads: 1) Suitable to 1064nm wavelength YAG laser cutting system. 2) Suitable to laser power less than 1000W. 3) Spacing between the exit of the nozzle and workpiece is 1-20mm adjustable, response time is less than 5ms, and the control precision is 0.2mm. 4) Independent, complete Z-axis control and adjustable focus position. Also there are some functions such as automatic/manual mode, up/down jog control, auto tracking/auto reset function, multiple gap setting, zero shift compression etc 5) Numerical control port can easily be connected to most controllers. The cutting system automatically tracks the marking head open, close or back to zero. 6) Multiple focusing lenses with various focal lengths. 7) Cooled nozzle design used for high pressure cutting. 8) Over travel protection, collision protection and power-off protection etc. Structure Description High power Nd:YAG self-floating laser cutting head consists of nozzle, focal lenses and auto-focusing system. Nozzle: nozzle is very important for laser cutter. Through in-depth research and tests, we have obtained a large of optimal data according to the different customers requirements to recommend the best suitable nozzle. Focal lens: in general, the focal lens system consists of a few lenses or non-spherical lenses. The focal length is longer, the focused beam diameter is larger, the power density is lower, but the depth of focus is longer, which is beneficial to cutting thick material. sales@sintecoptronics.com 23

24 Auto-focusing system: there is a capacitive sensor used to measure the distance between the nozzle and workpiece. The measured distance will be online fed backed and then the system will drive the step motor or servo motor to adjust the distance and always keep the distance same.

31 CO2 Compact Manual Attenuator We supply CO2 compact Manual Attenuators that allow you to vary laser output power. Our Manual Attenuators allow the user to externally vary the power delivered from the laser. Many lasers only vary their output power by pulsing full power on and off, and this does not always provide the fine levels of control needed for some materials. This device will give infinitely variable control of the transmitted beam from approximately 6% to 100%. Using enhanced coated Brewster plates the transmittance range can be changed from 0.04% to 98%. When used with a laser of up to 100W the CO2 compact Manual Attenuator can left be air-cooled. When used above 100W then the optional water-cooled jacket should also be fitted. Features: Vary power delivered from the laser Optional cooling jackets Provide fine levels of control The attenuator is a cost-effective solution to low-power beam delivery that is easy to understand, easy to use and easy to order.

32 Beam splitter, which splits input laser beam into two or more beams (called sub-beam), is widely used in laser applications. Sub-beam can be delivered in wanted direction with optics, and all the sub-beams can be assigned different power percentage to cater versatile applications. Laser Beam Splitter Typical beam splitter produced by Sintec is a 2-channel splitter which divides the input beam into two equal power with same optical properties. Multiple reflectors and transmissions are employed in the splitter system, and special optical design delivers sub-beams with same property, which enable the same spot size and equal power density at the focus of following convergent optics, so that same application performance can be achieved in different channels. High efficiency can be obtained where a beam splitter is involved to output multiple laser beams. It is the most perfect solution for multiple beam processing production lines because of the beam splitter s high advantages: multiple channel, no power difference, sharing laser source and low cost. The power difference measurement has been conducted in the 2-channel beam splitter of a fiber laser marking system, which shows only 0.37% power difference between 2 channels.
