Choosing the Right CNC Cutting Machine: Automatic Lathe or Multi-Spindle Lathe

Due to technological advancements, Computer Numerical Control (CNC) machines have been integrated into different industries. The CNC machine can effectively produce symmetrical objects of various cuts, shapes, and details on a rotating workpiece.

CNC machines are considered as the “mother of all machine tools” because of their amazing features and benefits over traditional lathes, including:

The CNC machine is designed to produce large quantities of products.

The operator feeds to the machine with crucial details of the product.

Automated machines reduce workplace injuries.

How Does It Work

The CNC lathes are rapidly replacing the conventional production lathes due to its ease of setting up and operation. Designed with the most modern processes and carbide tooling, it allows you to create mechanical parts, programming tool paths using a computer-aided design and manufacturing software (CAD/CAM) for customization or manually upload the file to the machine. Once the program is set, the machine will begin work with minimal supervision. Additionally, you can also modify and display the program, along with a simulated view of the process.

The CNC lathes can be designed in various ways, depending on the machine manufacturer. However, all CNC lathes have significant similarities in their composition, including:

This modern machine comes with a complete enclosure to ensure industrial safety standards. With the advancement of technology, manufacturers of CNC lathes are continuously upgrading the system by incorporating various types of user interfaces. Hence, it is incredibly vital that all machine operators are properly trained to keep up with the latest updates and reap the maximum benefits of using the machine.

The precision of CNC lathe machine cannot be underestimated.

Automatic Lathe

CNC automatic lathes are closely related to NC lathes. This type of machine is designed to produce loads of product without human hands involved. It has two types of work materials used:

Multi-spindle lathe has faster cycle times than a single spindle NC lathe.

Multi-Spindle Lathe

The multi-spindle automatic lathe can be used in turning, boring, chamfering, grooving, threading, and drilling by moving the workpieces between six to eight machining positions. Overwhelmingly fast cycle times can be delivered by this machine by dividing the operation into six to eight processes. Additionally, this machine is four to five times faster than the single spindle NC lathe. However, its speed can change depending on various conditions.

Choosing the Right Cutting Machine

Oil mists are a natural product of machining processes that need to be monitored and controlled. An overabundance of oil mist particles in a shop, warehouse, or manufacturing floor can bring health hazards. Exposure to these pollutants can cause various skin diseases, respiratory health issues, and in extreme cases, cancer.

Oil mists are formed when water and metalworking fluids interact with moving parts during machining

Sources and effects

How are oil mists formed? Oil mists are created when metalworking fluids (MWFs) are sprayed to metal components to lubricate them or maintain their coolness. MWFs are used in many machining processes like drilling, turning, milling, grinding, and finishing.

Manufacturing lubricants are classified into two categories:

Regardless of the type of fluid used, the application of any coolant will generate and emit fine mist particles in the air. This is the inevitable result when water and oil are mixed in the process. The emissions that result from this process are lumped into three categories:

These emissions might contain various additives like alkanolamines, colourants, dispersants, corrosion inhibitors, dyes, and anti-mist agents. Consistent exposure to these additives can pose a range of health concerns and create a hazardous work environment.

MWFs can cause skin irritation and respiratory disease

According to the Canadian Centre for Occupational Health and Safety (CCOHS), the ingestion of or contact with MWFs may result in the following major health concerns:

Contact dermatitis is one of the skin conditions that can occur after constant exposure to synthetic, semi-synthetic, and soluble fluids. Tiny slivers of metals, also known as fines and swarfs, can worsen existing skin irritations. The chances of absorption through the skin are higher when a person has cuts or breaks in his skin. Fluids can also splash onto the skin during the cleaning and maintenance operations done on the machines.

Generally, the severity and the type of illness depend mainly on what MWF is applied, the mode of contamination to the fluid, and the duration and frequency of the person’s exposure to the MWF.

Employers should keep the air quality in their plants healthy and safe

Maintaining healthy air quality

Canada has set numerous regulations in place that aim to protect workers from the health hazards caused by exposure to oil mists. The Canada Occupational Health and Safety Regulations cites that employers shall develop and maintain a “procedure for the control of the concentration or level of the hazardous substance in the workplace.” It also suggests that procedures requiring the use of such substance shall be “limited to the quantity required for one work day” to minimize exposure to workers.

Wear complete Personal Protective Equipment and keep the workplace clean at all times

Other recommended control measures are the following:

When handling metalworking machines and MWFs, employees should be provided with PPE that give them thorough protection from chemicals and fluids, sharp-edged parts, metal particles, machine noise, and falling debris. Clothing that can resist chemicals is also necessary.

Make sure to wear clean work clothes. Minimize the risk of accidental ingestion by not eating, drinking, or smoking within the work area. Maintain cleanliness in the entire work area. Clean the machines thoroughly and change the MWF when needed. If you see oil on the floor, clean it up and locate the source to stop the leakage right away.

Oil mist extractors help keep workplaces clean and healthy.

How does an oil mist remover work?

An efficient oil mist removal device is a perforated drum with a set of vanes which rotates at high speed. The oil mist is removed from the dirty air through coalescence, a process where droplets combine to form larger drops, making the removal of oil from the air more manageable. Once removed, the clean oil is pushed back to the machine, and the clean air is returned to the workplace.

The benefits of controlling oil mists include:

Good air quality in the workplace boosts employee health and productivity. All manufacturers have the opportunity to make their workplaces cleaner and healthier than before. An essential step toward that goal is to eliminate oil mist that can result in serious occupational illness.

People working in manufacturing facilities (metalworking, milling, and machining) that use oil-based cutting fluids are exposed to the adverse health effects of oil mist. Machines used for production applications, such as screw machines and machining centers, centreless grinders, and CNC machines, creates fine oil mist, which contains undisclosed additives that are harmful to human health. Ensuring an oil mist-free environment is highly crucial to safety and cleanliness in the workplace.

What is Oil Mist

Oil mist is fine airborne droplet particles that measure above one micron in size and can be the result of emulsions or oil smoke. Emulsions are used as coolant or lubricant during machining of ceramic or metallic materials, or to aid in chip removal. They usually consist of 90 to 95 percent water, with the rest of its composition being soluble chemicals. Mineral oil-based metalworking fluids combine with water or oil to produce oil smoke, whose droplets measures below one micron in size. Oil mist from emulsions and oil smoke are equally unhealthy. Emulsions can pass into a worker’s nose and windpipe and can be inhaled or swallowed, while oil smoke can reach into the lungs.

Exposure to oil mists can cause eye, nose, and throat irritation. Oil mist can also coat the work environment creating an oily, slippery surface. Slippery floors, tools, and controls can be considered safety risks that could potentially lead to a variety of work-related accidents.

How Oil Mist is a Danger to Our Health

Prolonged and repeated exposure to oil mist can be a health risk. To protect workers’ health and wellbeing, a facility should ensure that there is an efficient ventilation system installed. With millions of people from around the world working in manufacturing and industrial facilities, it is vital to reduce, if not prevent, exposure to the dangers of oil mist.

The following are some of the most common health problems associated with exposure to a large concentration of oil mist or oil smoke:


Oil mist can stick to your skin, clog pores, and cause acne

Respiratory System:

Oil mist exposure can cause respiratory problems like bronchitis

The National Institute for Occupational Safety and Health (NIOSH) also added to be wary of the following symptoms:

Oil mists can irritate your eyes

People working in manufacturing and industrial facilities are exposed to oil mist in three ways: skin exposure, aerial exposure, and ingestion. However, the skin is the most frequent route of exposure. Occupational health experts claimed that skin exposure causes more than three-quarters of all occupational disease. While exposure to oil mist alone can be a danger to the health, it becomes more hazardous when other foreign materials and chemicals contaminate the suspended oil.

How to Protect Your Workers

Appropriate PPE helps protect the health of your workers

Although oil mist suspended in the air can be invisible, evident signs of oil mist can be seen on the floor and wall surfaces, lights, and on the machinery. It also has an easily identifiable odour.

NIOSH reported that employees working close to a machine that uses oil fluids or in facilities with inadequate ventilation systems have higher chances of exposure to metalworking mist or aerosols. Additionally, failure to maintain machinery regularly can also increase the risk of oil mist exposure.

This is why OSHA has recommended that facilities implement a comprehensive metalworking fluid system management program, which includes regular monitoring and recording of metalworking fluids, engineering controls for oil mist, and training and educating employees about the hazards associated with oil mist exposure.

Other effective ways to reduce oil mist exposure:

Oil mist collectors can effectively remove dispersed oil from the air
