Our CNC Prototyping Process

Rapid prototype machining services typically involve a few different processes. Each one is slightly different and may be required depending on the specifications of a particular part or component.

CNC Turning

CNC turning consists of locking a metal or plastic workpiece on a chuck, and then rotating it at a high speed while a computer-guided cutting tool removes material from the workpiece to complete the desired shape. This process is typically used for bar-shaped or cylindrical components.

CNC Milling

CNC milling uses a 3- or 4-axis CNC milling machine. The metal or plastic workpiece is held in place at the center of this machine. Then, one or more rotary cutters are used to remove material from the workpiece and create the desired shape.

Wire EDM Machining

It uses a specialized electrode that delivers ultra-high precision cutting, and an electrical current to remove material from the workpiece. The wire electrode never actually touches the workpiece, causing little thermal damage or warping.

CNC Grinding

It is similar to traditional metal grinding. This method uses a computerized grinding wheel to remove material from a stationary metal workpiece. It can be used with abrasives to polish and deburr workpieces.

Laser Cutting Services

It uses a powerful laser to cut through metals such as steel, aluminum, and other similar materials. The laser burns away the metal, allowing the sheet of metal to be trimmed. It is also utilized to create slots, holes, and other geometries.

Sheet Metal Fabrication

Sheet metal fabrication involves cutting sheet metal, then bending it using a press to create the desired component. Compared to CNC machining, it is often a cheaper option to build components that have uniform wall thickness.

Materials For Custom CNC Prototyping

We offer CNC services for a wide variety of metals and plastics at CNCNOW, including the following:

Precision Metal Prototyping

Aluminum – custom aluminum machining is strong and corrosion-resistant and is ductile and easy to machine.

Stainless steel – Stainless steel cnc machining is inexpensive and has very useful physical properties like corrosion resistance and high durability.
Mild steel – Mild steel machining has a low carbon content and is easy to work with, since it’s less brittle than other types of steel. It’s also very inexpensive.

Alloy steel – Many different steel alloys containing between 5-50% of other alloyed elements are available.

Brass –CNC machining Brass is an alloy of zinc and copper, with other elements occasionally added. It is very ductile and has good corrosion resistance.
precision metal machining
Copper – machining Copper is conductive and is very soft and ductile, so it is typically alloyed with other metals before being machined using CNC equipment
Titanium – machining Titanium is often used in aerospace, medical devices, and high-performance cars due to its strength-to-weight ratio and ductility.
CNC Plastic Machining Services

Polytetrafluoroethylene (PTFE) – Known as Teflon, this plastic is highly heat-resistant and is a very good insulator.

High-density polyethylene (HDPE) – This strong, weather-resistant plastic is often used for outdoor goods, pipes & fittings and chemical containers.

CNC Plastic Machining Services

ABS – ABS is strong, highly machinable and offers good impact resistance

Nylon PA – Nylon PA is resistant to impact and breaking, as well as abrasion and chemicals, making it common in many different fields of engineering

Polycarbonate (PC) – Polycarbonate is very durable and has many desirable properties for consumer goods and electronics

Polyoxymethylene (POM) – Known as Acetal and Delrin, POM is a very versatile and durable plastic that is inexpensive and easy to machine using CNC tools

Acrylic (PMMA) – PMMA is very strong and durable, and often used for aircraft canopies, skylights and in automotive applications.

CNC Prototyping Surface Finishes

We offer in-house precision CNC machining surface finishes including:

Anodization (Type II &; Type III) – Anodization creates a layer of anodic oxide on aluminum, which provides corrosion resistance and durability, and can be used to change the color of the component.

Electroplating – Electroplating is used to add a thin, uniform layer of metal to a completed metal part.

Bead Blasting – Bead blasting uses tiny glass beads to create a uniform satin or matte appearance on the completed part for aesthetic purposes.

Polishing – Polishing is used to remove surface imperfections and buff the part or component to a mirror-like finish.

Brushing – Brushing uses a fine, unidirectional grit to create tiny grooves in the metal component, leading to a unique appearance.

Laser engraving – Laser tools can be used to etch brand names, serial numbers and other information into completed parts.

Powder coating – Powder coating is used to add a layer of polymer paint, which enhances the appearance of the part and also adds durability and corrosion resistance.

As machined – This surface finish includes removal or sharp edges and deburring, but no further finishing. Tool marks will be visible. Typical surface roughness is around 126 μin.

5 axis cnc machining

5-Axis CNC Machining Capabilities

At CNCNOW, we have a full range of 5-axis CNC machines that provide us with the ability to manufacture even the most complex part geometries.

Not only can these machines move horizontally (X and Y axes) and vertically (Z axis), but they include two additional “rotary axes” (A and B). This allows the part to be milled and cut from almost any direction.
5 axis machining increase efficiency, as there is no need to manually rotate or flip parts. In addition, it’s easier to save money on labor costs, and fewer machines are needed to create the same volume of parts. All of these benefits add up to better results and cost savings – which we pass onto our customers.

CNC Machining Tolerance

AT CNCNOW, we use the latest 3 and 5-axis CNC machines that offer high precision and accuracy, and ensure tight tolerances for all of our machined parts. Our standard milling tolerances are:
cnc tolerance
We can also offer custom tolerances within ± 0.020mm (.0008”). With the use of wire EDM machining, tighter tolerances may be available depending on your project.

How Much Does It Cost To Get A Part Machined

The cost of CNC machining depends on a number of factors. The biggest factor is your design, what do you want to be worked upon? It’s always a good idea to decide your overall budget before scheduling your machining project.
Here is what you need to think about while deciding the cost :
  • Estimated cost of your project
  • Labor cost
  • Cost of using different machines
  • Additional cost
  • The rate card of CNC machining company
After deciding all these factors, get multiple quotes from the reputed CNC companies and decide the best one.
Here are the aspects on which the overall CNC machining cost depends :
  • The complexity of the design is the first factor that affects the cost of production. Naturally, the more complex and detailed designs will cost more than the simple designs. This is because the more intricate designs take time to program.
  • The size of your order is another factor that affects the cost of CNC Machining. A small volume will cost much less than a bigger order.
By determining all these aspects, you can get a rough idea about the total cost of machining your parts.

Benefits of CNC Services
