Laser Cutting Machine – The Ultimate Tool for High Precision Laser Cutting

Fiber Laser Cutting Machine is the next big thing in the field of engraving. The use of Laser technology for engraving and curving out detailed structures isn't new; the market already consists of its highly efficient version. It delivers an impeccable quality of work in quick time, and is best for use on metallic surfaces like brass, copper, steel, titanium etc. The ultimate measure of work is the superb quality of the cut and the enduring tolerance level, which doesn't harm the material. 

Efficient Features 

Its high-quality work and superior precision depend on its inherent features. The fiber laser cutting machine has a good shelf life as it has the capacity to work for 100, 000 hours at 3000-watt power. The optional table shuttle optics system has various kinds of optical fibers – 50mm-200mm fibers used according to the nature of the material. There are various ways to control the gas pressure like the gas regulator, safety shroud etc. The most important features are the German drives powered to give high throughput results in a quick time.  

Using Fiber Laser Cutter

It is indeed very easy to operate this machine. However, it involves certain risks as it cuts through materials at high speed. It can cause damage to both the materials and the workers. A detailed knowledge of the types of machine models and the materials used is essential. Be sure you choose the exact machine, which supports your material or try consulting the manufacturer for this purpose. 

A trained individual should operate this after thoroughly reading the manual. Taking care of warranty, safety mechanisms, and other technical details are equally important. Moreover, various parts of the machines like nozzles, operators, press brakes, lens focusing system and material refilling systems need a routine checkup. When you satisfy yourself with all these checks and controls, it is now the time to start working on your Fiber laser cutter.

Thus operating a Fiber Laser Cutter is as simple as its cutting work – quick, precise andefficient, but it involves some risks. There is only one chance of correction, and once it is done, you can't revert to the original. So be careful and make the most of it.


The Game Changing Paradigm of ATC Routers from China

In the world of CNC machines the ATC model (automatic tool change) holds pride of place in any workshop that uses CNC technology for manufacturing. The automatic tool changer the capability of reducing the time a project remains on the machine. Take this comment from Mr. Jeff Elders from California in America. He is in the business of custom cabinets manufacturing and commands a stellar reputation for quality and maintaining deadlines in that order. To paraphrase his experience he was able to complete the milling operations on 14 full sized sheets of material in just fewer than five hours. This project included shelving for 30 cabinets. Here is the statement that extolls the virtue of the ATC Router wherein he states that he will recover the cost of the machine in just doing this one project. Moreover the precise nature of cutting and multi-faceted operations of the ATC allows almost zero scrap material. The last statement is a fitting testament to the ATC machine’s precision and speed of operation.

The Use of ATC Routers in Volume Oriented Manufacturing

Mr. Elders purchased the 1325 model of OMNITEC’s ATC Series Router. Omni CNC Technology Co., Ltd is China’s leading supplier and manufacturer of CNC Routers. They started manufacturing operations only in 2009. In less than 8 years they have become a name synonymous with CNC router technology. Mr. Elders is not a stranger to manufacturing cabinets using CNC technology. He settled on the 1325 ATC model after due diligence of several CNC Router manufacturers from all over the world The 1325 is a linear type ATC router and is desirable for its high performance characteristic notwithstanding its affordable price. Mr. Elder’s calculation of recovering the cost of the machine from doing just one type of project was based on its affordable price point and accurate machining capability.

Omni Follows the Doctrine of Jobs

Omni CNC mirrors the aphorism of Late Mr. Steve Jobs when he said that he makes products that help change the world. (Sadly Apple has lost this doctrine in its search for making profits for after the passing away of Mr. Jobs there has been no innovation worthy of the Apple name – just a change in the name of the model). OMNITECH make machines that bring not only profits to people who own the machines but they help in producing the end products faster and lower the cost of production. Definitely a game changing philosophy and practice from Omni CNC.

 The opportunity provided by ATC routers in volume oriented manufacturing is immense and revolutionary. They can process a variety of sheet sizes and produce individual parts in such a way that practically eliminates scrap. It is a complete win-win situation for the fabricator and processor of mass manufacturing. Add to the above basic feature other properties such as low maintenance and ease of operation and you have a winner. This blog is proof that innovation is not country or color of skin specific. It is passion that drives innovation.


Into the 5th Dimension as in Multi-Axis CNC Routers

Vertical machining by CNC Routers is of the 5-axis type. Depending on the material or the substrate the operations are either milled or routed. The vertical machining machines are moving on 5-axis. The cutting element may move up or down or move sideways or move forwards and backwards. The work holding surface may also be moving. All of these operations are employed during prototyping which is akin to two or more people chiseling and removing or shaping the clay model in automotive renderings. 

The question asked by non-technical people is this ‘there are only three dimensions, so how does this machine work on 5-axis”? Here is a good explanation of the 5-axis conundrum.

 Imagine that the object is placed on the working surface and it is moving. The cutting tool on the spindle is fixed in one position.

Here are the possible movements.

• The objects move up and down while the spindle is stationary.
• The object moves side to side
• The third movement is the forward and backward movement.
• The fourth movement is the side to side rotation changing the angle of the cutting bit
• The 5th movement is the back and forth movement again changing the angle of the spindle.

Now change the moving object to the action of the spindle and reverse the movements meaning the object is fixed and the spindle is moving. Check this video (https://www.youtube.com/watch?v=9zvUm5R3wbk) and you will notice the action of the spindle replicating all the movements and making the explanation of the 5-axis clear.

 Omni CNC Technology Co. Ltd from Jinan in China makes the 5-axis Router CNC in the video. They are one of the leading innovators in the CNC domain with several types of CNC machines in their catalog. The OMNI 5-axis CNC router has a heavy duty gantry as well as the machine table that provides excellent rigidity during the high speed milling operations. Primarily used for mold making (as in the video) the machine can also process other materials such as resin tooling board, expanded polystyrene and other composites used in mold design and large metalloid molds used in aviation. The machine’s forte is 3d surface engraving and shape cutting.


Artistic Engraving and Carving with Updated Software and Robust CNC Machining

Commercial signage has gone beyond basic design concepts involving straight lines and right angles. Production routing tools in CNC machining are capable of complex shapes. The tooling ensures maximizing usage of material while minimizing machining times. The complexity of curved shapes which was operationally difficult has now emerged as an exciting routing technology.It is possible due to new software tools such as true shape nesting. The software acts in tandem with new toolpath cutting strategies. Even tool bits have undergone fluting design changes that allow ramping in and out of the material. Cutting times have reduced enormously due to multi-tool pocketing. Pattern texturing for signage as in the YouTube video (https://www.youtube.com/watch?v=3EmzRxC9ODw) is due to enhancing profile cutting along vectors which change the Z-axis cutting depth in a random fashion. The result is a stunning and unique texturing that adds interesting and unique features to signage carving.

Toolpath Strategy

Software advancements with updated editing and designing tools allow importing and editing projects. For example, the signage in the referenced video contains different vectors. The tooling bit is following a vectored tool path algorithm, but the CNC carving to an onlooker appears random. Toolpath strategy is one of the important features of both CNC Router and the software implementing the G-coded design.

Robustness of CNC Machine

The Router in the video is OMNITECH’s 1325 model which is a proven CNC performer and famous worldwide as among the best CNC Router for sign making. The video exemplifies the wood engraving of an elaborate logo design routed with extreme precision at high speed. The Router is heavy duty making it suitable for sign making, prototyping, and woodworking among other functions. It is a versatile artistic carving tool when used with new interactive tooling software. Fileting tool paths allow vector geometry to reduce the points of arc segments and converting into a smooth curve. Converting 2D drawings into 3D component construction is comfortable with advanced tooling software which the capable 1328 model can perform complex routing effortlessly.

Curved decorative panels and signage architectural elements are efficiently designed and routed on CNC machines. The 1325 model is ideal for outdoor and indoor sign cutting on several substrates such as MDF, acrylic, engineering plastics, and non-ferrous metals among others. Accessories such as fixing a rotary device to the Sign making 1325 CNC Router allows indexing as a 4th axis for processing structural columns. Adding a dust collector is advantageous when working with wood and plastic.

Artistic manufacturing is a combination of efficient CAD design such as OMNI CNC and integrating with Computer-aided manufacturing (CAM) technology. It brings complex artwork to life as in the video. The creative process of using lines, arcs, and other geometry for positioning the x, y and z coordinates allows free styling that was unimaginable in the past. The future of CNC machining and new technologies in the CAM domain such as generative designing (artificial intelligence (AI) tools, cloud computing enable CNC machines to generate designs on the fly) is already underway. 


Cutting Edge Engraving Through CNC Machining

CNC engraving technology has evolved in the last decade as computer-aided design and manufacturing embraced various industries. The advantage of minimum lead times has allowed faster production. It does not matter whether it is a prototype or repeat machining of design; the technology is available as the file is in the CNC computer’s memory. Stored files already have the calculation of the earlier tool path which allows machining a design again. Software programs that enhance design methods are available off the shelf. The programs are easier to learn.

The quality and speed of the engraving are relatable to both the software program and the build quality of the CNC router.

CNC Routers for Engraving

The engraving on solid wood and non-ferrous metals require that the build quality of the CNC Router is strong. Any basic type CNC Router uses 3-axis configuration which means that solid object on the Routing table provides stability during the engraving process. Among several manufacturers of CNC Routers Omnitech from China has created a niche in the manufacturing of affordable CNC Routers for engraving. 

The OMNI 1325 model is the perfect engraving CNC Router; not only it is robust in build quality it is priced reasonably, making it affordable for production as well as interior designers.

The 3-axis control motor on the 1325 model is AC servo type. Construction is of robust build and heavy duty suitable for woodworking, channel letters, sign making, custom millwork, engraving, artistic sculpting among others. There are other models in the same range with Model OMNI 3030 ideal for hobbyists because of the working size of 300 mm x 300 mm. The OMNI 1224 has aworking size of 1200 mm x 2400 mm. With a decent 2,2 kW spindle at 24000 rpm, this router is a big seller for engraving large pieces.

Software Quality

The programs based on advanced vector algorithms with a simple interface allows editing so that modifications to the tool path is easily incorporated. Some advanced tools use mirroring and merging 3D relief which makes repeating symmetrical design modeling simple and easy. Other advanced engraving techniques use fade relief tool for creating shadow perspectives. Engraving is a form of sculpting. Smart engraving strategies utilize software programs for the engraving of text and irregular shapes.

The engraving process of incising a design on a hard surface was primarily used in the jewelry trade embellishing gold and silver vessels. The process graduated to printing plates where the intaglio etching method oncopper printing plates became the standard. It was after the introduction of computer numerical control that engraving by CNC machines became sought after for the ease and speed. Jewelers have the small 3030 model in their premises allowing them a high degree of personalization and the capability of engraving on awide variety of surfaces. These surfaces could be round as in rings, vessels, cups or flat surfaces. With software capable of translating picture half-tones to G-code the process of engraving images has become simpler and artistic.
