CFW’s manufacturing facility is constantly upgraded with latest machinery, ensuring competitiveness, consistency, best quality and a fast aftersales service. The CFW group’s experience as a successful industrial design and manufacturing company demonstrates our understanding of the need for outstanding metalworking services. We provide CNC machining, CNC machining, CNC punching, CNC bending, CNC forming, CNC spinning, stainless steel fabrication, and Laser Profiling.

The type of machining you will need depends on the accuracy, repeatability and production rates required as well as the final product that is desired.

CNC Machining

We provide CNC turning and milling services for computerised mass production of a wide variety of items, including hubs, pulleys, blades and other parts.

CNC turning is used to make parts by rotating a work piece and feeding a cutting device into the material. The machine used can thus be considered a kind of lathe. The shape of the cutting tool and the angle at which it strikes the work piece can be varied to produce various parts that are symmetrical around some axis of revolution, with many types of profiles and threaded surfaces if needed. Chess pawns are a type of item that can be made with CNC turning. Multiple axes can be used for more flexibility, and the process can be combined with CNC milling for a great range of parts.

CNC Punching

CFW provides fast, accurate and economical punching of mild steel and aluminium sheet up to 6.0 mm thick and stainless steel up to 3.0 mm thick. Our equipment and experience enable us to produce high-quality sheet metal products at competitive prices.

We use an Amada CNC turret press brake with a press capacity of 29-30 tonnes, capable of handling sheet sizes of up to 1270 mm x 3660 mm. Cost-effective for low-volume runs and excellent for fast prototyping, this machine can blank or punch to produce a wide variety of complex parts. With the right tools, it is suitable for producing vents, louvers and extrusions of various kinds.

CNC punching lets one make parts from a work sheet by preparing a part programme that runs on a computer. This determines the movement of the work sheet on the machine, the tools used, and punching and forming, thus automating the operations needed to produce the part. Many CNC punching machines can now do laser or plasma cutting, automated loading, unloading, storage, retrieval or sorting of parts and other operations when optional extras are added.

With a full turret punch press, work sheets can be moved, tools selected, and various auxiliary operations can be performed to further automate parts production. The reprogrammable nature of CNC turret punch presses means that runs of various sizes can be produced and part designs can be easily revised at little or no retooling cost.

CNC Bending

CFW offers a flexible and effective service for fast and precise sheet metal bending. With modern, electronically controlled press brake machinery incorporating automatic bend sensing technology, we handle jobs requiring bending lengths of 4000 mm and press force of up to 320 tonnes. Our skilled CAD designers and press brake machine operators are of great value for the sheet metal fabrication industry.

With CNC bending, plastic deformation of the shape of a material normally takes place around a single axis. This distinguishes it from press forming, which is used to create more complex shapes using multiple axes.

The main failure mechanisms for bending with softer materials are adhesive and abrasive wear. Harder materials may be susceptible to additional failure mechanisms such as galling and plastic deformation.

Modern press brakes typically use “air bending”, where the die assembly is such that the bend in the work sheet occurs between areas that touch the die.

CNC Forming

CFW handles CNC forming for complex components.

CNC forming applies plastic deformation to a material by using a computer-controlled press brake. Shaping, making shallow impressions and flanging can be done on a part that has been taken from sheet metal. It is similar to bending, but can produce more complex components.

Forming can be done on aluminium as well as a variety of steels and other alloys. Applications include the fabrication of metal framing and housing for specific parts, mass production of machine and equipment brackets and some part decoration.

CNC Spinning

CFW uses a computerised multifunctional machine that can function as a CNC spinning lathe as well as doing punching.

Stainless Steel Fabrication

We offer cutting, bending, and welding facilities for light and heavy gauge stainless steel plate. Our flame-cutting and welding services include the most common industrial arc welding processes. These include both types of gas metal inert welding (metal inert gas: MIG; and metal active gas: MAG), usually favoured because it is fast and versatile.

MMA (manual metal arc welding), also called by other names such as flux shielded arc welding, shielded metal arc welding (SMAW) or “stick welding”, is the most preferred method for maintenance and repair because it is simple, flexible and economical. Usually, the sheet metal used is more than 3 mm thick. It is also used in steel construction and fabrication.

Tungsten inert gas (TIG) or gas tungsten arc welding (GTAW) is used where more control is needed, often producing a better weld, but is much slower and more difficult. It is often used for aluminium and alloy fabrication (e.g. stainless steel). It works best for sheets less than 0.6 cm thick.

Industries served include the automotive, food processing and power generation industries. We can produce sheet metal racks, housings, tanks, frames and many other products.

Laser Profiling

We offer laser profiling facilities, providing excellent service, competitive pricing and on-time delivery. Our dedicated CAD designers and machine operators will produce custom parts at low cost.

For high-precision, versatile and cost-effective cutting of parts, laser cutting is often the solution. The narrow kerf that is produced helps to reduce the amount of the original material that is wasted, and there is little burring.
