Renderfact CNC Machining
At Renderfact, we use advanced equipment to offer you a variety of CNC machining services including milling, turning, swiss machining, surface grinding and much more. Regardless of the manufacturing process used to create the end-use part, CNC machining is widely used by designers as a means of creating early and late-stage prototypes with short turnarounds times. Prototyping in CNC allows designers to rapidly iterate ideas without expensive tooling or longer wait times. Compared with other rapid prototyping methods, rapid CNC machining allows us to get tighter tolerances in prototypes in real materials fast. Using our state-of-art 3, 4 and 5-axis CNC machining centers, our team of engineers and machinists program the equipment to optimize cutting time, surface finish and final tolerance to meet your specifications.
CNC Prototyping is the preferred option to bring new design to life among the other rapid prototyping methods unless the products are designed for 3D printing or other methods only.
Below are some of the benefits of CNC Machining and How it Works!

CNC Milling Services
The CNC milling machine combines the accuracy of computerized controls to rotate and position multi-point cutting tools. CNC milling machines are built for precise manufacturing and repeatability which makes them perfect for rapid prototyping and low-to-high volume production runs. CNC milling is a subtractive manufacturing process. It starts by fixturing a block of metal or plastic material inside the CNC mill. Using G-code, the CNC machine is programmed to rapidly mill out parts from the block of raw material until you have the final shape you want.
Our 3- and 5-axis CNC machines are equipped with various toolsets to maximize efficiency and production speed. For intricate and complex geometries, a 5-axis CNC milling machine will move along three linear axes while simultaneously moving along two rotational axes. CNC mills can also work with a variety of materials from basic aluminum and plastics to more exotic ones like titanium — making them the ideal machine for almost any job. When the run is complete and your required surface finish is applied, parts are ready to be packed and shipped.
CNC Turning
Like CNC mills, CNC lathes can be easily set up for high repeatability, which makes them great for everything from rapid prototyping to low and high-volume production. CNC Turning is a manufacturing process in which bars of material are held in a chuck and rotated while a tool is fed to the piece to remove material to create the desired shape. A turret, with tooling attached is programmed to move to the bar of raw material and remove material to create the programmed result. This is also called “subtraction machining” since it involves material removal.
Our Multi-axis CNC turning centers allow for multiple machining operations to produce cylindrical parts with external and internal features, such as slots, tapers, and threads, etc. making them a cost-effective option for complex geometries that would otherwise require multiple machines or tool changes in a traditional machine. Render fact’s turning capability will allow you to produce highly accurate, high quality parts to meet even your most demanding requirements.
CNC Swiss Machining
A Swiss CNC machine is a modern precision manufacturing machine that can produce extremely small parts quickly and accurately. CNC Swiss turning machines have a sliding headstock that operates with a guide bushing, which provides excellent stability for the bar stock while complex slots, holes, threads and multiple diameters are machined into the workpiece. CNC (computer numerical controls) allow our Swiss turning equipment to be highly automated, providing consistent, precise parts at tight tolerances from the first component off the machine to the final production unit.
Swiss machines have exploded in popularity within precision manufacturing. The combination of high precision and high production volume make Swiss machines a critical piece of equipment for shops that want to produce a large volume of small and intricate parts with little margin for error. Render fact’s Swiss Machining capabilities allow producing high quality and extremely precise parts for industries such as aerospace, electronics, firearms, automotive, hydraulics, and medical.
Brass Parts
Brass machining is used in a wide variety of applications and industries, including medical, electrical, plumbing, and even consumer goods. Companies prefer small brass turned parts and components because it is one of the easiest materials to machine, it is cost efficient, and extremely durable. Machined brass fittings are often used in electronic hardware because of its low strength and weight properties. Additional brass machining applications include engineering, plumbing, and steam work because machined brass fittings have a low friction coefficient and high corrosion resistant properties.
Renderfact is a medium to high volume brass Components supplier who produce not only Brass Turned Parts but also brass inserts, electronics components, brass fasteners, brass casting and forged components, brass connector pin, brass hardware, brass fittings, brass auto component, brass electrical component, brass gas component, brass cable glands and brass component assembly.
The varied products we manufacture are in high demand persistently meeting our client’s expectations in brass parts product performance, service and delivery. Our company caters to an enormous clientele network. We can deliver to a customer base with the aid of an extraordinarily dexterous workforce that is proficient and dedicated.

Finishes
Renderfact provides surface finishes on all CNC parts, including anodizing, electroplating, bead blasting, polishing, brushing, powder coating, and painting.
Anodizing improves corrosion resistance, enhancing wear resistance and hardness, and protecting the metal surface. Widely used in mechanical parts, aircraft, and automobile parts, precision instruments, etc.
Bead blasting results in parts with a smooth surface with a matte texture. Used mainly for visual applications and can be followed by other surface treatments.
Powder coating forms a durable, wear resistant and corrosion resistant layer on the surface of parts. Powder coating can be used to apply colors to parts and is compatible with any metal.
Electroplating can be functional, decorative or corrosion-related. Many industries use the process, including the automotive sector, in which chrome-plating of steel automobile parts is common.
Polishing is the process of creating a smooth and shiny surface, either through physical rubbing of the part or by chemical interference. The process produces a surface with significant specular reflection, but in some materials is able to reduce diffuse reflection.
Brushing is a surface treatment process in which abrasive belts are used to draw traces on the surface of a material, usually for aesthetic purposes. Most commonly applied to aluminum.
Painting the surface of a part improves its aesthetic appearance and can provide brand recognition to consumers. In addition, painting can have a protective effect on parts.
