Not only do these machines produce a large noise, but also when they aren’t carefully handled, they can cause damage. 

Whether you are visiting, managing, or working within a CNC turning machine shop, there are a few general safety rules that you have to adhere to. Not only will this ensure your own safety, but also the safety of the machines and people working in the area. 

Here is a list of all the machine shop safety rules you should be aware of: 


Like stated before, operating these highly-intelligent machines are much more complex than it might seem. It’s important that only skilled workmen use the CNC turning machine. 

If you aren’t as familiar with a new piece of equipment, then you have to go through the instruction manual first and memorize the controls to be able to operate it safely. Consult an experienced machinist for help. 


After a few heavy duties, machines do tend to be run down quite a bit. To avoid machines getting even more damaged, it’s important that they undergo regular inspections. Check for obvious problems like cracked tools, damaged chuck and shields, or any dull and blunt tools. 


For artisans who are part of the prototype creation, it is important to wear the proper personal protective equipment (PPE). This includes proper-grade safety goggles, hearing protection, and non-slip safety shoes with a steel point.

Never wear gloves while operating equipment in a machine shop. Because you will have to work very accurately, gloves can take away the sense in your finger. As well as making the risk bigger of being snagged by a machine. 

According to the shop’s safety rules, you’ll might have to wear protective eye goggles and ear protection. Exposure to high volumes at an extended period of time can cause hearing loss in the long term. If you are someone working with loud machinery, then you should always make sure that you are wearing high-quality ear protection. 


Because there are a lot of parts that are turning and rotating, it’s important that users don’t wear anything that might be caught up in the machine’s part. Avoid wearing necklaces, bracelets, watches, and rings. 

Some horror stories have revealed the loss of a finger when the machine gets hold of a part of jewelry. If you are adamant on wearing your wedding band, get a silicone replacement band. Silicone is much more flexible and can break off easier than a titanium wedding band. 

Avoid wearing any loose clothing or long sleeves that might be snagged up by the machines. Tie back your hair to avoid the same thing happening. Even if you are just doing a quick walk through the machine shop, you should be given the proper PPE to ensure your safety. 

While working with the different CNC turning parts you should adhere to the following rules:


Always ensure that the workpiece is securely clamped in place. It’s important that it doesn’t jump around on the desk, but rather stay fixed in one spot. When it’s secured it will also cut more accurately.  


Especially when the CNC machine is running, you should never reach into the moving parts. Rather use a small vacuum or brush to clean debris off of the surface. Never use your naked hands, compressed air, or a rag. 

It goes without saying, that some cutting tools within the machine’s construction is terribly sharp. Avoid grabbing the tools with full force that might leave you with some deep cuts and the machine with some blood splatters. 


To prolong the life of all machines in the shop, it’s vital to do the proper maintenance on them. Use soft vacuums and brushes to clean leftover material, dust, and debris from the surfaces. Remove sharp edges and burrs as soon as possible. 

During inspection, you should check whether the tools are in working condition. Tools should be set correctly and sharp. Use specific equipment to put tools in place instead of using naked hands. 

Other maintenance tasks can include lubricating different parts, adjusting the machine in accordance to the manual, and checking the working state of the motor. Always perform these maintenance tasks when the unit is locked and plugged out of the electrical socket. 

Workers should use the proper manufacturer’s instruction when replacing coolant. 


Tripping over spilled water or sliding across the floor will be a recipe for disaster. That’s why it’s just as important to keep the areas around the working machines hazard free. Remove all obstacles and mop up any spillage immediately. 

This goes for cleaning chips and loose materials from machinery as well. Using compressed air can blow debris under the wiper seals and bearings, or fly in the air potentially harming a passerby. 


The shop should have all relevant safety and warning signs available. Whenever there’s a unit that is under maintenance, it should be tagged to let other workers know. 

Other areas that are under construction or maintenance should also be marked with a clearly readable sign. Any barriers or steps should also be marked with clear signs. 

If you are a maker in search of a high-quality CNC machine shop to produce your design, then you have to check whether the shop has its safety rules and regulations in line. This will also ensure the quality and correctness of your product. 

To ensure a safe and secure working environment, it’s important that all employees, visitors, clients, and managers are playing an active role. Employees shouldn’t disturb operators who are operating an underpower machine and avoid startling each other. When you see something that looks out of place, it’s your responsibility to let a supervisor or manager know.
