Oil Skimmer Blog

In the world of manufacturing, precision and efficiency are paramount. CNC (Computer Numerical Control) machines are the backbone of many industries, providing the ability to create intricate and accurate parts with incredible precision. However, these machines often face a common challenge: the accumulation of unwanted coolant and cutting oils on their surfaces, leading to decreased performance, tool wear, and the risk of environmental contamination. This is where CNC machine oil skimmers come into play.

What is an Oil Skimmer?

An oil skimmer is a mechanical device designed to remove unwanted oils, grease, and other hydrophobic liquids from the surface of coolant or wastewater. In the context of CNC machines, oil skimmers are used to remove cutting oils and coolants that accumulate on the surface of the coolant reservoir. By doing so, they help maintain the quality of the coolant, extend tool life, improve machining precision, and contribute to a cleaner and safer working environment.

How Do CNC Machine Oil Skimmers Work?

Oil skimmers are relatively simple yet highly effective devices. They operate on the principle of buoyancy and surface tension. Here's a basic overview of how they work:

1. Skimmer Design: CNC machine oil skimmers come in various designs, but most employ a rotating or moving medium (usually a belt, disc, or drum) that is partially submerged in the coolant or wastewater.
2. Oil Attraction: The submerged medium attracts the oil or grease due to its hydrophobic nature. As the medium rotates or moves, it collects a layer of oil on its surface.
3. Separation: The medium with the collected oil then passes through a scraper or wiper mechanism, which removes the oil from the medium's surface. The oil is directed into a separate collection container, leaving the coolant or wastewater behind.
4. Recirculation: The cleaned coolant or wastewater is returned to the CNC machine's reservoir, ensuring that the coolant remains in good condition for machining.

Benefits of CNC Machine Oil Skimmers

1. Extended Tool Life: Accumulated oil and grease on cutting tools can lead to premature wear and diminished tool performance. Oil skimmers help maintain a cleaner coolant, thus extending the life of cutting tools and reducing tooling costs.
2. Improved Machining Precision: Oil-contaminated coolants can compromise the precision and accuracy of CNC machines. Oil skimmers contribute to a cleaner work environment, resulting in more consistent and accurate machining.
3. Reduced Maintenance: Clean coolant reduces the frequency of coolant changes and extends the lifespan of coolant filters, reducing maintenance costs.
4. Environmental Compliance: Properly managing and disposing of oil and coolant waste is crucial for environmental compliance. Oil skimmers help collect and separate oil from the coolant, making it easier to handle the waste in an environmentally responsible manner.
5. Cost Savings: By enhancing tool life, reducing maintenance, and improving machining precision, oil skimmers can lead to significant cost savings in the long run.

CNC machine oil skimmers are valuable tools for maintaining the performance and longevity of CNC machines. By efficiently removing unwanted oils and grease from coolant reservoirs, they contribute to cleaner, more precise, and more environmentally friendly machining operations.

The Oil Concentrator operates without any reliance on electrical components or moving parts, simplifying its design and maintenance. Its functioning is straightforward: it directly receives liquid from the skimmer. The fundamental principle at play is gravity separation. To facilitate effective separation, the Concentrator tank is sized in a manner that allows sufficient duration for the oil and water to naturally segregate.

When it comes to discharging the liquids, the process is neatly organized. Water is released via a tube positioned with an open end close to the lower section of the Concentrator, whereas oil is directed through a separate drain outlet located near the upper part. As fresh liquid enters the Concentrator, the already separated water and oil are compelled to exit through their designated discharge tubes and ports. Enhancing this process, a sludge screen contributes additional dwell time, furthering the separation process. Importantly, this screen also acts as a safeguard, preventing any debris from compromising the quality of either the separated water or oil streams.

The Abanaki Oil Concentrator

The Abanaki Oil Concentrator plays a dual role, acting as a highly efficient oil-water separator capable of managing the recycling or responsible disposal of either liquid. In most operational scenarios, Abanaki skimmers excel at retrieving oil while leaving behind minimal traces of water. Nonetheless, as surface oil diminishes to a fine layer, measuring just 1/16 of an inch or even thinner, an increased amount of water or coolant might inadvertently get collected alongside the oil. 

To tackle this situation, the Oil Concentrator collaborates seamlessly with an oil skimmer, offering a conclusive phase of separation. The outcome is twofold: it provides water or coolant that can be channeled back into the recycling process, and it yields oil that is nearly devoid of water, rendering it suitable for efficient disposal.Installed at the discharge end of the oil skimmer, this oil water separator comes complete with mounting bracket, removable sludge screen and drain plug for easy cleaning. An optional thermostatically controlled heater is available for use with thick oils, or when the application is in freezing temperatures. (A heater should not be used in environments where explosive fumes might be present.)

Abanaki highly recommends pairing the Oil Concentrator with all belt oil skimmers for optimal outcomes. This combination greatly boosts skimming efficiency and also brings down the costs linked with oil disposal. This partnership doesn't just improve equipment performance – it saves money too. The Oil Concentrator refines the oil-water mix, making the separated oil purer and easier to dispose of. This reduces the expenses associated with disposal and supports eco-friendly practices. In essence, Abanaki's suggestion to use the Oil Concentrator with belt oil skimmers is a smart way to work smarter, cut costs, and be environmentally responsible.

Coolant oil skimmers typically don’t come attached to CNC machines when they are newly bought. This is because nobody wants to admit that the brand-new machine is eventually going to leak oil into the coolant. This looks good on paper, but there is a reason why so many coolant oil skimmers are bought annually. 

CNC machines are bound to have at least a small amount of oil leaking into the coolant at some point. The skimmer will remove this oil from the top of the coolant for disposal. Without some type of coolant oil skimmer, the coolant life will be dramatically decreased. These small coolant oil skimmers will save you money throughout the operational life of your CNC machine.

The Crucial Role of Coolant Oil Skimmer on CNC Machine

A coolant oil skimmer plays a crucial role in enhancing the performance and longevity of CNC (Computer Numerical Control) machines. These machines rely on coolant oil to lubricate and cool the cutting tools, which is essential for maintaining high precision and preventing damage due to excessive heat. However, coolant oil tends to become contaminated with various substances such as tramp oil, metal shavings, and debris during the machining process. This contamination can adversely affect the machining process, leading to reduced efficiency and increased maintenance requirements.

The implementation of a coolant oil skimmer effectively addresses this issue by efficiently removing the contaminants from the coolant oil. By removing tramp oil, which is the accumulated oil from leaking machine parts or hydraulic systems, the skimmer prevents the formation of a sticky residue on the workpiece, reducing the need for post-machining cleaning. This results in improved surface finish and higher product quality. Moreover, by removing metal shavings and debris, the skimmer helps prevent clogging of the coolant system, ensuring smooth coolant flow and minimizing the risk of tool damage.

Additionally, a coolant oil skimmer contributes to cost savings and environmental sustainability. By efficiently separating tramp oil from the coolant, it extends the life of the coolant oil, reducing the frequency of coolant replacements and the associated costs. Moreover, the skimmer aids in the recycling and reusing of the separated tramp oil, minimizing waste generation and promoting environmental conservation. Overall, the benefits of a coolant oil skimmer on CNC machines include improved machining performance, reduced maintenance requirements, enhanced product quality, cost savings, and a more sustainable manufacturing process.

Different Types of Coolant Oil Skimmers

There are several different types of coolant oil skimmers available for CNC machines, each with its own unique design and method of operation.

1. Belt Skimmers: Belt skimmers consist of a continuous belt that is immersed in the coolant. The belt attracts and collects the floating oil as it passes through the coolant, and then the oil is scraped off the belt and collected in a separate container.
2. Disk Skimmers: Disk skimmers utilize a rotating disk that is partially submerged in the coolant. The disk's surface tension attracts the oil, which is then scraped off the disk and collected for removal.
3. Tube Skimmers: Tube skimmers employ a hollow tube or suction head that is inserted into the coolant. The oil is drawn up through the tube by a vacuum or suction mechanism, separating it from the coolant, and then it is transferred to a collection container.

Each type of coolant oil skimmer has its advantages and is suitable for different applications based on factors such as the type of coolant used, the volume of oil to be removed, and the specific requirements of the CNC machine.

Choosing a high-quality belt oil skimmer for removing tramp oil from machine tool coolant is challenging.

Belt oil skimmers use an endless belt of corrosion resistant steel or synthetic medium, which is lowered into the tank or vessel to be skimmed. The belt passes through resilient wiper blades where the oil is removed from both sides of the medium.

Despite many belt oil skimmers looking similar, quality and versatility can vary. This video shows what to look for. 

How Do Belt Oil Skimmers Work?

Belt oil skimmers utilize the differing specific gravities between oil and coolant/water to remove tramp oils. A motor driven belt that is typically constructed of an oleophilic, or oil attractant material, is placed into a coolant sump or reservoir. As the belt moves through the coolant, it attracts tramp oils. The oil is scraped off by a wiper and deposited into a container.

Belt oil skimmers provide a simple, dependable and cost-effective method for removing oil, grease and other hydrocarbons from water.

Tube oil skimmers offer an inexpensive, efficient solution for removing tramp oil from coolant especially if limited overhead space is an issue. Tube oil skimmers can be used on machining centers with little or no access to the coolant sump from above. Plus, tube oil skimmers can remove oil from chip conveyors or enclosed machining centers.

However, finding the best tube oil skimmer for an application can be difficult. This video shows how to use this type-skimmer correctly along with seven features of a high-quality tube skimmer for coolant maintenance.

Why Tube Oil Skimmer?

Tube oil skimmers are great for some specific applications where oil needs to be removed from water or coolant. The basic principle is that the tube will reach into the water and break the oil’s surface tension. This is the same way that the belt skimmers work.

The tube oil skimmer can be easily mounted on the side of virtually any machining center coolant sump. By use of an existing opening or by making a small access cutout, the collector tube runs through the surface of the coolant and collects the unwanted oils. The oil then flows out the discharge tube into any waste oil container for easy disposal.

Many people prefer the belt skimmers when there is direct access overhead, but this is often not the case. Some applications will not have vertical access to the liquid. Tube oil skimmers allow the unit to reach in a side access point and go down to the surface. The tube oil skimmer can be an easy solution to a troubling problem.

Oil Concentrator (Oil Water Separator)

Under most operating conditions, tube oil skimmer picks up oil with only small traces of water or coolant. However, as surface oil is reduced to a thin layer (1/16 inch thick or less), more water (or coolant) may be picked up along with the oil. When used in tandem with the tube oil skimmer, the oil concentrator solves this problem by providing final phase separation. The result is water (or coolant) available for recycling, and virtually water-free oil for disposal.

This oil concentrator is non-electrical and contains no moving parts — it simply receives liquid directly from the tube oil skimmer. Water discharge is through a tube that has an open end near the bottom of it, while oil flow is through a separate drain port near the top. As additional liquid enters it, water and oil are forced out through their respective disposal tubes.

Disk oil skimmers offer an efficient option for removing tramp oil from coolant yet finding a high-quality unit offering durability can be tough. When properly selected and applied, disk oil skimmers are highly economical solutions for separating oil from water to allow its reuse or safe disposal.

How Do Disk Oil Skimmers Work?

Disk oil skimmers rotate a disk-shaped medium through the liquid. Oil is wiped off and discharged into a collection container in a manner similar to belt oil skimmers.

When specifying disk diameter, it is important to consider reach, the portion of the disk that actually gets immersed. Less disk area in the fluid means less oil removed. Obviously, fluctuating fluid levels can be a real problem.

Also, it is important to look at how much of the disk the wipers are actually wiping. If they wipe only 2 inches from the edge, then any reach into the fluid beyond 2 inches is wasted. As a result, removal capacities for disks can be relatively low.
