Business Overview

Many products that businesses use and sell are made through a highly precise process called computer numerical control (CNC) machining. CNC machining businesses specialize in this type of manufacturing, which uses computer-controlled machines to produce products with a high degree of accuracy.

Who is this business right for?

Anyone who likes building things and working with their hands may enjoy running a CNC machining business. Although machined parts are made by computerized equipment, there still is a substantial amount of hands-on work involved in the manufacturing process.

What happens during a typical day at a CNC Machining Business?

CNC machining involves loading materials into machines, programming machines, and letting the machines run. Depending on the work being done and type of machine, it may be necessary to manually operate the machine or manipulate the parts at certain times.

When not working directly with machines, business owners and employees take customer orders, order additional supplies and ship completed orders. Additionally, there is usually a designated person who schedules the machining work to maximize efficiency. This person may be the business owner or an employee.

What is the target market?

Most CNC machining businesses serve other businesses, although a few make products that are directly marketed to individuals.

Business-to-business machine shops can be divided into two categories: job shops and product shops. Job shops take orders from clients and then make items that are built to their client’s specifications. Product shops design and create their own products, then sell those products to businesses.

How does a CNC Machining Business make money?

A CNC machining business makes money by selling machined parts. Prototypes may be sold as single items, but most orders are for large quantities of the same part.

What is the growth potential for a CNC Machining Business?

A CNC machining business can remain a small operation that’s run by one or two people, or it can grow to be a large company that completes orders for clients throughout North America. Arsenal Products is a relatively small CNC machining business in Austin, Texas, and Plethora is an example of a larger company.

Getting Started

What are some skills and experiences that will help you build a successful CNC Machining Business?

Business owners must know how to operate CNC machines, which is more complex than using non-computerized equipment. Most business owners have previous experience working as a CNC machinist for other businesses, and those who aren’t already familiar with these machines may want to spend some time working for someone else before opening their own shop.

Additionally, business owners can take CNC machining classes. Vocational schools, technical schools, and community colleges sometimes offer such courses, and there are also online programs. Tooling University and SME are two organizations that offer online courses.

What are the costs involved in opening a CNC Machining Business?

CNC machines aren’t inexpensive. Lathes alone can cost anywhere from a few thousand dollars to tens of thousands, and many shops have several pieces of equipment. Nevertheless, there are ways for business owners to keep their startup costs relatively low -- and it’s possible to start a CNC machining business for very little.

First, many business owners start out working from their garage or a workshop that they already have. This eliminates the need to lease a workspace until there’s regular work.

Second, business owners don’t need lots of equipment or the fanciest available equipment when first getting started. For example, Todd Adlon opened his shop with just a mill and a lathe, adding equipment later on. Several other business owners got started with just a basic lathe.

Having only basic equipment will limit the amount and type of work that a CNC machining business can do, but there’s enough basic work available to support a small shop that has only one or two machines. Specifically, there are lots of clients who need prototypes made, and larger shops often won’t make one-off prototypes.

What are the steps to start a CNC Machining Business?

Once you're ready to start your CNC Machining Business, follow these steps to ensure that your business is legally compliant and avoid wasting time and money as your business grows:

  1. Plan your business. A clear plan is essential for success as an entrepreneur. A few important topics to consider are your initial costs, your target market, and how long it will take you to break even.
  2. Form a legal entity. Establishing a legal business entity prevents you from being personally liable if your CNC Machining Business is sued.
  3. Register for taxes. You will need to register for a variety of state and federal taxes before you can open for business.
  4. Open a business bank account. A dedicated checking account for your CNC Machining Business keeps your finances organized and makes your business appear more professional to your customers.
  5. Set up business accounting. Recording your various expenses and sources of income is critical to understanding the financial performance of your business. Keeping accurate and detailed accounts also greatly simplifies your annual tax filing.
  6. Obtain necessary permits and licenses. Failure to acquire necessary permits and licenses can result in hefty fines, or even cause your business to be shut down.
  7. Get business insurance. Insurance is highly recommended for all business owners. If you hire employees, workers compensation insurance may be a legal requirement in your state.
  8. Define your brand. Your brand is what your company stands for, as well as how your business is perceived by the public. A strong brand will help your business stand out from competitors.
  9. Establish a web presence. A business website allows customers to learn more about your company and the products or services you offer. You can also use social media to attract new clients or customers.

What are some insider tips for jump starting a CNC Machining Business?

Todd Adlon and many other business owners warn against growing a CNC machining business too quickly. Investing in equipment and hiring employees before a business is ready to only increases overhead and makes it harder to remain profitable.

Instead, a strategy that slowly grows a CNC machining business is more likely to provide long-term sustainability and profitability. Business owners should only hire employees once there’s enough work for them do to, only purchase machines once there are employees to operate them and only lease larger spaces once there’s the equipment to fill it.

Earning Potential

How much can you charge customers?

The cost of CNC machining job varies greatly depending on the type of product ordered, how many are ordered and whether there are special setup requirements. Kennewell CNC Machining uses the following rubric to set prices for lathe jobs:

  • A setup charge of $120 to $160
  • Raw materials are marked up by 20 to 35 percent
  • Special fixtures are added onto the total cost
  • Machining is charged at a rate of $60 to $150 per hour
  • Post-machining work that’s subcontracted is marked up by 20 to 35 percent

What are the ongoing expenses for a CNC Machining Business?

The ongoing expenses for a CNC machining business can be substantial. They include raw material costs, utilities, equipment maintenance costs, lease payments, and employee salaries.

How much profit can a CNC Machining Business make?

Most successful CNC machining businesses operate on a 10 to 15 percent net profit margin. For a shop that has just $500,000 in annual work, that generates a profit of $50,000 to $75,000 on top of the business owner’s salary.

How can you make your business more profitable?

CNC machining businesses can increase their profitability and diversify their revenue by slowly expanding the machining services they offer. Shops can do this without taking on too much risk if they only expand when a contract for a different type of work becomes available. If a contract will pay for a new piece of equipment, then taking on that creates an easy way to afford new machinery that lets a business expand its offerings.
