Getting a Custom CNC Machining Quote

Before you can begin your custom CNC machining project, it all begins with getting a machining quote. CNC machining is a cost-effective method of on-demand manufacturing, particularly for metal parts. In fact, a custom CNC machining project may be more affordable than you would initially estimate. So, if you are in need of machining services but unsure of the machining costs and prices involved, get a machining quote with Prototek and get all the details you need.

What is Involved with Machining Parts?

CNC machining is a manufacturing process in which factory equipment and machinery are regulated by pre-programmed computer software. From grinders and lathes to mills and routers, CNC can be used to operate a wide variety of complex machinery. Three-dimensional cutting tasks can be completed in a single set of prompts with CNC machining.

The CNC machining process begins by creating a 2D or 3D CAD drawing using special software, which is then translated to computer code for the CNC system to execute. With modern CNC machines, the actual production process is fairly automated. For parts that require multiple techniques, there may be manual movement from one machine to the next. However, many machines can combine multiple different functions.

Standard Costs Associated with a Machining Quote

There are standard line items associated with custom CNC machining quotes that can contribute to the cost of the overall project. These include operator and machine time.

Factors That Can Affect Machining Quotes and Costs

There are also additional variable costs, which determine the overall quote value. Here are the main areas that contribute to the cost of quote:

  • Material

    CNC machining is a reductive process, meaning it generally requires more material than other methods. These products are purchased in blocks by machinists, who measure the prices per block. Metals and plastics are the most popular materials used in CNC machining. Plastics are less expensive, but also less durable.

  • Finishes

    Surface finishes enhance the appearance of CNC machined pieces as well as their resistance to harsh environments. While they are beneficial for some projects, they boost machining costs.

  • Number of Machines Used

    Using more machines can increase costs, especially if the project requires manually moving from one machine to the next.

  • Turning vs Milling

    CNC turning is typically less expensive than milling, but it’s limited to round parts.

  • Lead Time

    Decreased lead time and rush jobs can lead to increased costs as machines may have to be cleared to push the job through the manufacturing queue.

  • Necessary Tolerances

    Tight tolerances can increase the cost of production. It’s best to only use the tightest tolerance necessary for your part’s use.

These are just a few of the costs that can impact machining quotes. CNC machining costs may also include wear and tear on the tools and design costs, among others. Fortunately, the internet has made getting a quote faster and easier than ever. So, stop the guess work and get a machining quote from Prototek today.
