Creating Laser Cut Stencils

Posted on December 17, 2016 at 11:20 pm

Laser cut stencils are used to create highly detailed and clean images as well as pieces of text that are then used for a variety of different purposes. They are often used by businesses as the clean and precise nature of the laser cutting process allows a professional, high quality image to be created.

Both large and small stencils can be created using a laser cutter as Laser cutters often have a large cutting area. If the stencil needs to be bigger than the initial cutting area, then it can be created in multiple sections which can be attached together. There are however limitations of the amount of detail that can be cut into a area on smaller stencils.

Stencils can be created out of a variety of different materials, from fabrics such as cotton and leather to paper, card, wood thin plastics and metals. Professional laser cutters often recommended a material thickness for the level of intricacy that can be achieved.

How Efficient Engraving Materials Save Energy And Money

Posted on November 27, 2016 at 7:51 pm

All engraving materials cost some kind of energy to produce, transport and use. This is known as the embodied energy of the material, and determines it’s overall energy consumption up to the point of manufacture and usage. Understanding this process and how it saves energy can not only improve knowledge of the origin of a material, but can also serve a manufacturing company for many years. Allowing the company to reap the rewards of energy efficency through understanding and application as to how it affects the cost of materials over time.

Embodied energy is the energy used throughout the lifecycle of the material; from the processing of raw materials, to manufacturing through to product delivery. If an engraving is constructed with poorly chosen materials, the embodied energy used could diminish or cancel out the benefits of years of sustainable use. In other words, using resources that are quickly accessable and applicable saves time and energy which in turn saves money over long periods of time.

Understanding The Different Types Of Laser Cutting Materials

Posted on October 27, 2016 at 8:00 pm

Laser cutting materials are used by a laser cutting machine in the production process. Since lasers are specialized machines they can only be used to cut certain types of materials.

Examples of materials that can be cut with a laser cutting machine are: Wood sheets, paper, card, clear cast acrylic, acrylic sheets, styrene, abs, polypropylene and other types of plastics. Depending on the material, there is usually no limit to the thinness of the material to be cut. However laser cutting is restricted when it comes to cutting very thick materials. But this can come down to the availability of equipment used by the manufacturer.

With regards to engraving a much broader range of materials can be etched upon. Examples include: Ceramic, glass, mirrors and aluminium. Etching can be done more easily and on more materials due to the fact the laser does not need to be as powerful. This

Using Laser Presets

Posted on September 26, 2016 at 6:34 pm

When using a laser engraver, the machine should have some suggested settings for cutting or engraving different materials and different thicknesses. These are important as understanding their functions can save a lot of time, as well as improve the quality of your engravings overall.

You should also be able to load these settings into your computer or laser and save them as presets. Be sure to name them something that makes sense so you can easily find them again.

Test cuts are also an important part of presetting a laser and should always be carried out when setting up a cutter before hand. This can be done by creating a small circle or square (about 1/4″ or 1/2″ wide) and cut out in corner or on some scrap material. Then can see if you need to increase or decrease the power before the final cut.

The Oxy-Fuel Metal Cutting Process

Posted on August 17, 2016 at 7:11 pm

Oxy-fuel cutting is most accurately described as rapid controlled rusting. It is used to cut metal using a process that breaks down the composition of the metal, rather than more conventional cutting techniques which cut with a direct, physical action.

Oxy-fuel cutting works by using preheat flames to raise the surface or edge of a metal, for example steel, to approximately 1800°F . Pure oxygen is then directed toward the heated area in a fine, high pressure stream. The steel is rapidly oxidised and is blown away from the cutting area, which leaves a cavity. The preheat and oxygen stream are moved at consistent pace to form a continuous cut.

For a metal to be cut with this process it must have oxides with a lower melting point than the base metal itself. If it doesn’t the metal will oxidise too quickly, preventing complete oxidation by forming a protective crust.

Low carbon steel and some low alloys are the only metals that can be cut effectively with the oxy-fuel process.

Quality Engraving Machines

Posted on August 7, 2016 at 2:40 pm

Engraving is a process of the art of etching, cutting, or carving a design or mark with an engraving equipment onto a metal such as steel or non-metal like plastic. The engraving equipments are typically pushed into the metal plate in order to produce cut & design of the marking. The deeper the marking or design penetrates into the material, the wider the line becomes. The link between the engraving width and dipping depth is determined by the top-angle of the tool. Result could be a decorative design or mark in itself, as when gold or silver are engraved, or may offer an intaglio plate whenever copper is engraved or a relief print-block when wood is engraved.

Different engraving-machines exist to work through diverse methods of marking or on different materials. You can find a complete line of high-quality engraving machines for sale at prices that cannot be beat. Engraving machines are available in a broad range of product types, brands and versions to meet the client’s needs. There are several different business applications for engraving machines. The machines will satisfy all possible engraving needs – from those just beginning an engraving business, to professionals having their own sign or gift shops – there is always an engraver for a wide-range of clients. Typically, if you manufacture or work with materials such as all metals types, glass, wood, crystal, plastic & acrylic, ceramics, rubber or cardboard, you might be able to gain from the use of these machine types. Materials that can be engraved include gemstones, wood, metal, plastic, leather and stone. (more…)

Completely Automated Control Processes

Posted on July 14, 2016 at 3:16 pm

Its common that most control processes have fully automated settings, controls that can function completely autonomously, independent of almost all human control.

An autonomous control process is made use of in big plants that use complicated technologies. This is due to the fact that these complex production plants are often completely made up of processes that are too complicated to be done by manual control. As a result, those processes are handled by machinery and robotic functions.

However, there is a share of automatic control between human and automatic input. This share generally tends to increase toward automation, even though in the more complex cases this growth is checked by the lack of suitable algorithms. Thus supervisory control will always remain necessary until algorithmization of all aspects of technological processes is completed.

There still remains methodological processes that will need to be resolved for completely automated control processes to be fully implemented.

An Engravers Toolset

Posted on June 19, 2016 at 7:57 pm

Engraving is a highly skilled profession, requiring a great amount of dexterity and ability in order to create detailed engravings. Of course, machines and computers arguably take out some of the raw skill required to engrave. But there still remains many manual engravers that hold true to traditional ways.

For traditional engravers the tools used are somewhat different to that of an engraver that uses a computer. For example, to manually engrave accurately a variety of hand chisels and a steady jig are necessary tools. Whereas an engraver who uses a computer controlled engraver may not even need a hand chisel. Instead relying on the engraving machines cutters to do most, if not all of the cutting and finishing.

However, there are tools that both manual and computer engravers make use of. A vacuum to clean away dust and excess debris, and a way of lubricating the engraving are both widely used by engravers in the very same way.

Modern Masonry Inscriptions And Engravings

Posted on May 30, 2016 at 4:53 pm

Many stonemasons create beautiful and informative engravings, which are made in such a way that they compliment the object that they are engraved on. Examples of this can be seen in  a number of instances in everyday life. Most commonly the stone inscriptions that feature on headstones to commemorate the life and death of those who have passed on. There are also other examples such as foundation stones for buildings and memorials that feature decorative stone engravings.

Creating stone engravings and inscriptions takes a great deal of skill. This is due to the hardness of stone which is naturally difficult to manipulate. However, using traditional techniques and tools to work with the stone, such as lettering chisels, points, mallets and toothed hammers, as well as modern power tools, an experienced stone mason can create detailed and decorative engravings, regardless of the rigidness of the stone.

Modern Diamond Cutting and Engraving

Posted on April 22, 2016 at 2:21 pm

There are many ways to cut a diamond, and since they are so high in value, the craftsmanship required for this precise task has maintained a high standard. Over the past 100 years the technology used to cut and engrave diamonds has developed to a point where lasers are now used to craft many modern diamonds.

The laser saw is one such technology that revolutionised diamond cutting when it was introduced in the 1930s. Laser equipment is far more accurate and time efficient compared to traditional methods such as manual sawing and cleaving.

The biggest advantage of laser cutting by far is its precision. One reason for this is that there is no cutting edge to wear down, and lasers are less likely to warp the diamond because the heat is confined to such a narrow space.

This method also causes less friction on the stone, it is also safer. Efficiency is also an advantage, as less manual labour and higher speed technology means faster production is possible.
