Types of CNC Machines Used by CNC Machining Shops
CNC manufacturing shops are nothing without the CNC equipment. These shops feature different setups of CNC equipment and mechanisms to carry out different manufacturing tasks. Moreover, CNC machines create parts from raw materials and shape them according to the design. They do different cutting, milling, and drilling procedures on the surface of materials to create precise products. Moreover, each shop has different machines according to their CNC machining requirements. The most commonly used machines include:
1. Milling Machine
A CNC milling machine works on materials to mold their shape into specific parts according to their design. This Machine has multiple axes from 3 to 5 and more. Generally, the manufacturers place the workpiece on the work table, which moves along the X and Y axes. The table holds the workpiece to the right position, and the spindle features cutting tools and moves along the Z-axis. So, the spindle performs the cutting operations while the table controls movements and feeds against the cutting tools.
This Machine is best for manufacturing parts with flat surfaces and simple designs. However, it can also work on complex geometries with other tools, including milling and drilling. Nonetheless, you can’t mix drilling with milling, as it has its procedure and drilling Machine.
2. Lathe
A lathe machine cuts down the material while it’s rotating to create a proper shape. In contrast with a milling machine, which moves the tool in a lathe, the material rotates, and the tool moves in that material. The material spins harmoniously around its center. Lathe machining is the best option for creating cylindrical and conical parts.
In Lathe machining, the spindle works across the rotating material and creates shape. Moreover, to keep the part in place, there is a clamp available named Chuck. You can adjust its position to align the part with the cutting tool. Besides, this Machine is also capable of CNC turning, Cutting, and many other similar operations.
3. Machining Center
The machining center is similar to a milling machine but with some new advancements. Besides, it offers better production outcomes and handles complex designs. What makes this machining type special is that it can handle different CNC machining processes, including milling and drilling. Moreover, the machining centers in different CNC manufacturing shops have automatic tool systems. Pre-setup saves you time and allows you to perform different operations simultaneously.
Generally, there are two main types of machining centers, including horizontal and vertical centers. Besides, there’s another universal version that includes both vertical and horizontal direction handling.
4. Grinding Machine
CNC grinding machines give proper shape and finish to the machine surface of parts. They make the surface smooth by removing debris, chips, and marks. The spinning wheel features an abrasive on its surface, which, when it comes in contact with the surface of a part, leaves a plane surface. With grinding, you fix the geometrical issues of parts and achieve a smooth finish. However, the result depends upon the speed of the spinning wheel, feed control, and abrasive material.
Manufacturers must carefully select the material type and grit numbers on an abrasive wheel to get the required results. The grit number means the fineness of the particles on the abrasive. Here’s their in-depth detail:
- Low Grit (10 – 24) is best for quick chunk and impurities removal.
- Medium Grit (30 – 60) is good for medium material removal and best for fabrication.
- Fine Grit (80 – 120) for high-quality finishes and deep material removal for finer polishing.
- Very Fine Grit (150 – 600) is suitable for premium finishes and achieves high precision with delicacy.
5. Drill Press
Drill Presses are best for precise results and deep drilling operations. They feature a drilling tool attached to a press, which can be automatic, hydraulic, or mechanical, and rotates the drilling. Subsequently, when the drill tip touches the material’s surface, it starts spinning and drilling into it.
Manufacturers can control the pressure that drill feed exerts into the workpiece manually and automatically. The automatic control systems can drill faster than traditional drilling methods.
6. Bandsaw
You can’t create parts directly from the raw blocks and large bars of materials by putting them directly in CNC machines. So, manufacturers must cut them into smaller parts before crafting their designs and geometries. Thus, the bandsaw’s work in CNC manufacturing shops is to cut through the big blocks and sheets of materials into smaller pieces. A bandsaw features long blades that cut through the material front by exerting forces through their edges.
7. EDM Machine
CNC machining shops also need machines with electrical discharge. These machines can manipulate hard materials and sensitive designs. Also, they are compatible with hard materials, complex shapes, sharp edges, micro-machining, etc. The EDM machine uses electrodes that touch the work metal and induce electrical discharge. Moreover, keeping the part and cutting tool in the dielectric fluid effortlessly removes the material.
With the high-temperature production during this method, the parts under manufacturing meltdown from the surface. Subsequently, the manufacturers can easily work on the part and create different geometries.
8. Inspection Tools
Expert CNC manufacturing shops don’t deliver the products right after their production. Rather, they ensure the quality of the products if they meet specific requirements. Thus, the production machines include inspection tools that monitor the dimensions, surface texture, characteristics, and tolerances to determine whether the end product is high quality. Some general tools for inspection include:
- CMM – Coordinate Measuring Machine
- Micrometers and Scalers
- Laser tools
- Hardness testing machines
CMM is the most sought-after tool for CNC machining shops, as it accurately measures geometries and surface quality.
Manual Vs. Automated Machining
In today’s fast-paced world, manual machining lags behind automatic machining methods. As the needs are diverse, the demand is high, so you can’t rely on manual labor and can’t find the experts to do quality work. So, what prevails over both is a new machining method that entails both manual and automatic work. That’s CNC machining, which includes minimum manual intervention and offers accurate results. Therefore, let’s take a look at a few major differences between manual and automatic machining:
| Aspect | Manual Machining | Automatic Machining |
| Accuracy | Depends upon the expertise of the manufacturer. However, humans are prone to make mistakes and can’t keep the details consistent when it comes to large-scale productions. | Can achieve high-end precision as low as ±0.0025mm. They can create similar products without any notable change in designs. Are best for large scale productions. |
| Consistency | The part designs are not consistent. If a human has to work on the same product design multiple times, each product will differ slightly. | You can have high-end consistent part design no matter if they are in high numbers. |
| Speed | Needs a lot of time and slows down the production process. | High-speed production with automatic controls and smooth machine movements. |
| Expertise | Need high skills of the manufacturers with years of experience in the same field to deliver quality results. | Need expertise in programming and setup, and the rest is just monitoring and making adjustments. |
| Cost Efficiency | From workforce to machinery and material waste, everything costs, but initial setup costs are relatively lower. | Initial set-up costs are high, however, they are best for a longer period and become cost-effective. |
| Flexibility | Highly flexible as operators can make changes in the designs as per requirements. | Have less flexibility as it needs changings in the software and tooling setup. |
