A machine shop refers to a place in which subtractive manufacturing takes place, where manual or automated CNC machines are used to manufacture products.

The word “shop” is not just simply as its literal meaning of “store”, but rather a floor, a building, or even a room in the initial stage of a small business, in which engineers and other technical staff members can operate machinery to bring an idea into production. This place makes it possible to produce different machined components including metal, plastic, and other types of parts.

The word “machine" refers to a piece of equipment with cutting tools to remove a plastic or metal block, or other raw materials, involving some processes such as turning, milling, drilling, etc. The facilities in a CNC machine shop may be variable from specific industrial needs and machining purposes, but the main concern is subtractive manufacturing equipment.

Up to now, machine shops have been well-developed at the cutting edge of manufacturing technology. It will greatly help many businesses stay in a dominant position in the market without high costly investments in hardware facilities or personnel training. Therefore, there is an increasing demand for the service of a machine shop, no matter of a small or large business.

Rather than only manufacturing products of a certain brand, as a third-party manufacturer, Runsom can provide customers around the world across various industries with online custom CNC machining services.

Things You'll Find In A CNC Machine Shop


A CNC lathe

A CNC lathe, is also known as a CNC turning center. The specified amount of material from the workpiece is removed when the component rotates with the lathe in contact with a cutting tool. It can achieve automatic machining and is perfect for symmetric components. Many functions such as facing, sanding, and knurling can be performed in a CNC lathe.


A bandsaw

A bandsaw is used to cut the blank stocks which are often supplied in the form of long bars of different diameters. A part is machined from a single piece roughly cut by the bandsaw before further cutting.

Drill press

A drill pressA drill press is viewed as the basic manufacturing machine tool. It is used to drill holes into any kind of part. The movement of a drill press is controlled by a lever. Besides drilling holes, it can also be applied to various manufacturing work, given its more accuracy and stability than handheld drills.

Milling machine

A milling machineA milling machine removes a block of raw materials from the workpiece with rotary cutters. Extensive machining operations can be carried out since there exist many series and sizes of milling cutters for conducting various kinds of cut, from threading to roughing. It's feasible to machine an irregular surface with a milling machine, but a flat surface would be preferable. It is usually used in some operations like boring, gear cutting, slotting, and drilling.

EDM equipment

EDM equipmentEDM (Electrical Discharge Machining) is referred to as a process where particles from the surface of the part are vaporized by electric currents. This method ensures the part not to be deformed when processing, allowing the cutting force to be close to zero. This process is greatly ideal for dies cavities and hardened aerospace parts.

Machining center

A CNC machining centerA CNC machining center is an improved version of the CNC milling machine, allowing it to conduct high-grade subtractive manufacturing with a Computer Numerical Control (CNC) system. It makes it possible to produce almost any shapes you want with a 3, 4, or 5-axis CNC machining center. The number of axes significantly determines the complexity of the part geometry it can make and has an impact on production cost. It is ideal for precision and complex parts due to its unmatched capability, easy setup, and high surface finish.

Grinding machine

A grinding machineA grinding machine employs a high-quality grinding abrasive wheel to grind the workpiece, forming a highly precise dimension with neat surface finishes. Such an operation can make the rough surface smoother by removing irregularities. And it is only used for parts that require extremely tighter tolerances because it’s costly and time-consuming.

Surface finishing tools

Surface finishing toolsThere may require a surface finish to get additional properties for machined parts, like glossiness, smoothness, colors, or mirror-like surface finishes. These special treatments can be achieved by various pieces of equipment in a CNC machine shop that offers anodizing, polishing, and sandblasting services.

Coordinate measuring machine

A coordinate measuring machineA coordinate measuring machine (CMM) is a piece of control equipment used to measure the geometry of the part and evaluate its properties, ensuring the exact tolerances of the part and error-free operation of various orders. Besides, it can offer data reports on machined parts. The accuracy and quality of the part are guaranteed with a CMM.


Others in a CNC machine shopMachines in a CNC shop perform different manufacturing tasks, either manual machining operated by a machinist or equipped with CNC (Computer Numerical Control) technology.

Besides machinery, the raw material for machining parts can also be stored in a machine shop. However, materials may be stored elsewhere, for instance, in a warehouse, depending on the scale of the machine shop. Computers in a machine shop may also be applied to digitally design parts by machinists, which are generally equipped with CAD software.

Automated vs Manual Machines

Nowadays, CNC machining is indispensable, especially widely used for the bulk of its operations. Given the excellent advantages of the new technology, CNC machining shops could carry out all the operations that a manual machine could do, and even more, are replacing traditional machine shops.

The following shows several benefits that CNC machining confers to a manufacturing facility.

When it comes to mass production or prototyping, a CNC machine shop could be a primary choice for reducing a product’s time-to-market and ensuring market share. Moreover, digital models like CAD, and CAM software, are feasible in CNC machining operations. A 3D model takes less time than manually writing code and can be reused with a different manufacturing partner.

Dimensionally accurate parts can be manufactured in a CNC machine shop. Tight tolerance of CNC machined parts is realized and the value of the finished object is increased in high-volume or consistent manufacturing of the same object.

The process of CNC machining is carried out behind a guard even a closed transparent door, which minimizes the human element in the practical machining phase decreasing errors as well avoiding accidents. Its additional safety features are as follows:

  • Emergency stop button: To stop if there is any malfunction. It can be found in several locations for quick and safe access.
  • Guard fence: This fence covers the largest working area of the machine and stops the operator from carelessly getting too close to a running machine.
  • Noise-proof enclosure: This enclosure makes the operator free from noise and acts as a shield between the operator and the running device.
  • Curtain guards: This protects the operator from shavings and tool debris.
  • Contact mats: To prevent exposure to the moving arm in case of that an operator steps onto these mats.

A CNC machining center can be mounted with several tools at the same time. Moreover, some latest CNC machines are equipped with automatic tool changers. There is no need for human involvement during manufacturing upon loading tools into the tool holder. The desired finished model will be delivered by the CNC machine.

The production process of CNC machining can be operated overnight and with no need for breaks. Besides, it won’t cause undue wastage, making it possible to increase manufacturing volume and lowing production costs simultaneously. Also, the labor cost will be reduced as the process can be operated and observed by a single operator.

CNC machine

Manual machining remains its stage in the manufacturing markets regardless of the abundant advantages of CNC machine shops. It has its distinct benefits as well:

cnc shop grinding machine
Manual machines may be a better option for small-scale tasks that do not require complex fabrication of parts.
Also, it won’t create a heavy investment as CNC machines. The manufacturer can invest in multiple manual machines with the same quantity of funds without facing the risk of breaking the bank.
Furthermore, lower costs for the customer may result from the lower overheads.
More importantly, for small-batch orders, especially one-off parts and components that demand prompt delivery, manual machining can perform a remarkable strength over CNC machining.

Tips to Choose A Right CNC Machine Shop

If you are looking for a CNC machine shop for product development or business prosperty, there are some factors that you are supposed to consider.

You'd better give a call to the machine shop or even pay a visit to its facility at your convenience before working with it. It will let you clearly know whether the machine shop you're ready to cooperate with has advanced CNC machines, measuring equipment, experienced machinists, and quality inspectors.

The first thing you think of may be the price before you place an order with a CNC machine shop. Each one is delighted to cooperate with a machine shop that offers the lowest rates. However, you should keep in mind that a good price should never be at the expense of quality. Therefore, selecting a reliable machine shop may help to avoid lots of potential troubles.

Many machine shops may assure you that they can deliver your order within a specified time and budget, but it turns out to be a failure. You may get into trouble because the machine shop cannot deal with your projects timely. It might be more prudent to have a profound understanding of the capabilities and flexibility of the machine shop.

Before starting the production, one significant matter you should never ignore is to sign a Non-Disclosure Agreement (NDA) with the machine shop to make sure your design will not be revealed to any third parties.

CNC Machining FAQs

The main costs associated with CNC machining can be grouped into machining time, start-up costs, material costs, and feature costs. To reduce costs you need to understand the impact of these factors on cost.

  1. The best way to reduce machining time is to design features that can be machined quickly, for instance, choosing the correct radii for internal corners, reducing cavity depth, increasing wall thicknesses, limiting thread length, and designing holes with standard sizes.
  2. Material costs can be reduced by considering the size of the blank required, and the cost and machinability of the bulk material (softer alloys are faster to machine).
  3. Start-up costs can be reduced by reducing the number of part rotations or repositioning required to finish the part, for example, separating geometries into multiple parts that can be assembled later.
  4. Feature costs can be reduced by only using tolerances when strictly necessary, removing all text & lettering, and avoiding multiple surface finishes.
