Solid Wood Carving Routers

The woodworking video in the clip (https://www.youtube.com/watch?v=KTkr9jl8cU8) is a fine example of wood-carving on solid wood pieces. The eloquence of the curved design is poetry in motion. CNC woodworking routers achieve harmony and engineering precision for two reasons. The first is CNC language called G-code that determines the speed of the object (in the video the solid wood piece) . The G-code also determines the depth of cut as well as the profile of the cut. This gives the curve design the precision that evokes admiration. Not to be forgotten is the fact that the object is held stationary primarily due to the vacuum effect of holding down the object although in the referred video the work piece is kept stationary with the use of clamps.The use of vacuum is desired for accurate machining and carving and there is a cost element due to the technology whereas clamping technology is simpler and costs less.


The wood carving element in furniture decoration is become  niche business with interior designers customizing designs as per customer's likes and the resulting G-code created tool paths makes the job off translating the design into reality. Furniture, wardrobe panels, custom cabinets are all up for exclusiveness in terms of furniture concepts. The legs of the furniture are becoming ornate and baroque designs of the Victorian era are making a comeback.

The CNC router from OMNI-CNC from China (in the video) is a versatile machine. OMNI-CNC has developed several innovations for solid woodworking by producing high volume machines with 3-axis, 4-xis as well as 5-axis operations. Importantly OMNI-CNC have tailored their manufacturing activities in producing affordable routers. They have more than 100 designs that are easy to use and produce high quality wood engraving. Among their best sellers are the basic linear type ATX CNC Router (ATC is automatic tool changer), and the Carousel type ATC CNC Router. For specialized woodworking applications, the synchronized multi-spindle CNC Router as well as cabinet and door making CNC router are particularly useful for high volume woodworking projects. At the heart of woodworking OMNI CNC routers is the innovative vacuum technology that allows increased efficiency as well as productivity. Solid wood routing is possible by using matrix suction platforms giving the object total shear force absorption while remaining steady.

The affordable OMNI 1325 and OMNI 1530 are standard machines the world over for woodworking as well as non-ferrous metal routing applications. Capable of handling solid wood sheet sizes of 5' x 10' OMNI-CNC have stepped their game up with the production of models 2030 and 2040 that can take solid wood sizes of 7' x 10' and 7' x 13'. All these systems have a matrix table and vacuum pump that is very powerful giving 140 cubic meters per hour capacity. Vacuum hold down is best-in-class along with positioning systems via linear rail systems on all axis.

Latticed Screen Partition by CNC Router

The films in the 50s and 60s had a very strong architectural connect when showing women within their homes. Particularly oriental themed films showed women behind latticed framework. These were wooden screens and in the film, the wooden screens actually lit up the scene as it showed glimpses of women behind them. People noticed these screens and were astounded at the workmanship of the artisan. These screens were works of art and quite expensive beyond the reach of the middle class. Only very rich and wealthy people were able to afford these screens.


The time spent by master carpenters and hand engravers was a lot and in fact not many could be produced. However technology has come to the rescue of this art as CNC routers have revolutionized partition grille screen production. The language of the CNC router is called G-code and this versatile technology has brought engraving and cutting application on wood to another level. Looking at an example of this video clip (https://www.youtube.com/watch?v=vsyul6C_Wvg) gives an idea how this application used on a CNC router can produces breathtaking partition grilles. 



The CNC machine in the video is by OMNI-CNC that is one of the leading CNC router manufacturers in China. The speed of the machine is a phenomenal 5000 mm per minute using a tool bit that is 3.175 mm in diameter. The finished partition grille-screen size is 1600 mm x 500 mm (1.6 m x 0.5 m). The cutting edge is very smooth meaning that no further finishing is required. The OMNI linear ATC 1530 machine is very affordable as the video shows an 8mm thick MDF board being transformed into a wonderful grille screen.


This is a niche business for the use of CNC routers because partition grille screens are adorning many homes as the cost has become affordable. The use of screen dividers adds not only the decorative element but also manifests as a room divider. Geometric lattices are used in offices, restrants, shops and exhibition spaces.

Shuttle Engraving for Looms by CNC Routers

Precision machining of a shuttle used in textile looms has undergone engraving iterations in the process. Man invented the shuttle to help the weaving process. A weaving shuttle is shaped like a boat carrying a bobbin of thread across the warp threads to form the weave. Repeated movement of the shuttle from left to right and back creates the weave ultimately forming the pattern of cloth.

Shuttle Carving

When it was first invented carpentry and carving skills was required. The basics of shuttle design began from a crude boat design (by the way this design is still used) that held the bobbin of thread. Employing a drill brace and a couple of bits to bore holes into the shuttle was enough to ferry the bobbin back and forth. From hand tools has the shuttle carving and engraving metamorphosed today to CNC router applications. Shaping the shuttle from the outside to fine placements of holes to create shuttle eyelets is just a matter of minutes for CNC routers. To prevent wear and tear in the eyelets as the thread passes back and forth small brad is precision-engineered. The complexity of engraving in the olden times with basic carpentry tools is indeed admirable compared to modern carving and engraving precision employed by CNC routers. This double technology process optimizes working times and productivity.

A fine example of using CNC routers for engraving shuttles is captured in this video 


The CNC router is manufactured by OMNITECH from China. They are one of the leading manufacturers of CNC routers. A basic Omni CNC router is all that is needed for precision carving and engraving shuttles. The built-in controller is input with predetermined tool path files that can be used repeatedly. The art of weaving extraordinary designs using thread of different materials like plastics, nylon, wool, synthetic silks among others has created a spin off industry in handwoven textiles. Design houses have sprung up all over the world. These spin offs have redefined shuttle manufacturing. Emailing tool paths to woodworking shops with CNC routers and receiving manufactured shuttles, via mail is as easy as posting letters and receiving a reply. The speed of CNC operation makes it possible to order as many shuttles as possible.

CNC Routers Enhance Architecture Facade Design

The versatility of CNC routers is incredibly vast in scope and application. There are many areas particularly industrial application that offers creative expression. The example of creating stunning facades in building construction is a prime example.

CNC routers are commonly used in profiling aluminum sections for fabrication service industry. Substrates include aluminum composites, high pressure laminates, Acrylic, MDF Corian, HDPE among others that is regularly profiled and cut using CNC routers. Miller Design in Australia is one of the leading votaries of using OMNITECH's cutting edge CNC routers.

They provide complete integration of design to installation of curtain-walling systems, shopfront facades and roof glazing. They are a name to reckon with and won many awards for the high quality of their installations that involve intricate aluminum joinery.

OMNITECH CNC ATC (automatic tool changer) Router is essential equipment in Miller Design's arsenal. OMNI also offer production, technical expertise and consultation to Miller and this partnership is more of actual creative minds meeting on a common platform to produce architectural beauty.

Miller Design specializes in curtain-walling design where two or more floors of a front facing façade appear to be continuous and seamless. Reflective glass mounted on structurally glazed mulions which are concealed help this stunning architecture. Engineering design and accurate cutting of aluminum profiles is the expertise behind this kind of architecture design. Retrofitting existing buildings is also possible with curtain-walling.

Dejan from Serbia is another of those enlightened visionaries who uses OMNITECH's ATC type CNC router for aluminum composite machining. He uses thick aluminum sheets of 4 mm thickness while his panels range in thickness from 2 to 10 mm. Some of his windows, glass facades and ventilated facades are a joy to behold for structural as well as aesthetic appearance.

How CNC Router Could Benefit Cricket Bat Processing Business?

Cricket is a sport played mostly in countries that have a colonial history. As the colonies broke up and the sun began to set on the British Empire the game of cricket continued to thrive in these areas. There was however a jewel in the crown of the breaking British Empire. India at the midpoint of 1950s had a population around 350 million people. In a span of five decades, the population soon touched a billion and along with China forms the two largest countries in the world population wise. The winner is cricket. India rules the cricket world in numbers. The demand for cricket equipment is witnessing boom time.

Bat Manufacturing

Cricket bats are at the center of the equipment business. The bat manufacturing centers in England pioneered the use of English willow. As demand, outstripped supply Kashmir willow became the wood of choice and bat manufacturing concentrated in Kashmir. Being a populous country, every aspect of the bat was handmade and no two bats could be termed the same. Professional cricketers would spend days with a reputed bat-maker to personalize weight and size (within the stipulated laws of cricket) of the bat. A top rated cricketer would have a dozen bats in his kitbag.


CNC Router Process for Bat Profiling

England started the manufacture of bats using machines and soon it became apparent that CNC Router machine was the perfect tool for creating bats. Two-piece bats dominate the manufacture. The body of the bat is married to a cane handle via a splice. CNC routers have simplified the operation by using a single piece of willow (130 mm x 130 mm x 850 mm) that clamped onto a 12 spindle OMNI CNC Turner/Lathe Router. A milling tool of 1/2 x 60 and 1/2 x 120 is mounted and the block of willow fixed to the rotary device after finding the center point of the willow block. The CNC Router has the profile of the bat input into the computer, which guides the milling tool and process the willow block into the desired shape in one single piece.


Bat Dynamics

Bats usually have a raised ridge at the back of the bat and a straight face on the front. The front face meets the incoming ball and imparts force that is termed as a stroke. The force of the stroke is either brute power or timed stroke without using brute force. Twenty-twenty Cricket has changed bat dynamics resulting in strokes played of the back of the bat. Profile of the bat includes scooped back that is almost similar to the front without sacrificing the sweet spot on the face. Sweet spot’s indication is the noise of a solid thump when ball meets bat. The scooped back enables a batter to hit off the rear of the bat or reverse the bat in his hands in a lightning fast movement (called as reverse sweep).

Allen Tells You How to Process The Cricket Bat by CNC Router China-


Bat manufacturing business using CNC Routers is a game changer. Small CNC Router with two spindles can personalize bat for a person taking into account height, weight and batting style of the sportsperson. Small profiling adjustments to the blade of the bat smooth edges resulting in faster carry of the ball. The game of cricket is witnessing rapid changes in attacking style; more strokes are played when compared to before and cricketers are making serious money both on and off the field. It is not only international stars but also the lower ranked cricketer making a comfortable living.
