Oil-water separator is the most important environmental protection/circulation equipment in CNC machine tools.
In the machining process, a large amount of coolant (cutting fluid) is required, which will generate a large amount of wastewater and waste oil. These wastewater and waste oil will affect human health and greatly pollute the environment. Therefore, they cannot be discharged directly; they need to be separated and then treated separately. The separated water enters the water cycle for reuse, and the separated oil is treated harmlessly alone.
Gravity separation: Utilizing the different specific gravities of oil and water under the action of gravity to separate oil and water.
Air flotation separation: Making a large amount of grease or solid particles float up by generating air bubbles, and then utilizing gravity separation methods to separate them from the liquid.
Filtration separation: Utilizing equipment such as filters to separate solid particles through physical filtration methods.

Do all machine tools require an oil-water separator?
No. If continuous production is carried out for a long time, water-based coolant is used, there is a lot of lubricating oil in the guide rail, and the hydraulic system works for a long time, we highly recommend configuring it. If it is only occasional processing, running for a few hours a day with almost no lubricant leakage, the demand will not be so urgent
Is oil-water separator worth investing in?
For long-term production enterprises, it is usually worth it. The reasons include: Extend the lifespan of the coolant Reduce the frequency of fluid change Reduce the cost of waste liquid treatment Improve processing stability Reduce downtime maintenance
Which machine tools are suitable for oil-water separators?
The oil mist collector will collect the vaporized oil mist for unified treatment, which is a very important environmental protection equipment for CNC machine tools.
During the machining process, the high-speed rotating cutting tool will directly vaporize part of the cutting fluid, and the cutting fluid more or less contains oil ingredients inside. The vaporized oil and water are toxic to the human body and will also cause irreversible damage to the environment. The oil mist collector is specially used to collect the vaporized cutting fluid and degrade it for subsequent harmless treatment.
The high-speed rotating motor impeller generates negative pressure, sucking the oil mist produced during machining into the interior of the collector. Then, through the high-speed rotating oil-flinging disc, tiny oil mist particles are collided and remain on the filter media. After filtration, the collected oil returns to the machine tool tank through the oil return pipe to continue to be used, and the purified air is discharged directly.

Through-Spindle Coolant is abbreviated as TSC. A high-pressure coolant pipe is added inside the spindle, which is paired with a high-pressure coolant pump to achieve cooling of the spindle, tool, and workpiece from inside the spindle, while evacuating the cutting chips.
The traditional method of external water pipes spraying coolant is inefficient. During the machining process, the high-speed rotating tool will fling out the coolant, and in some extreme machining processes, the coolant cannot reach the true cutting center due to angle reasons, thereby leading to premature tool wear, a decline in machining accuracy, and an increase in the scrap rate. However, when the through-spindle coolant system works, it sprays under high pressure from the inside, so it can maintain the low temperature of the spindle, tool, and machining area at all times, thereby preventing thermal deformation, washing away cutting chips, improving machining efficiency and product surface quality, and extending the service life of the spindle.
Which materials are suitable for Through-Spindle Coolant machining?
TSC is effective for machining:
Carbon steel
Stainless steel
Tool steel
Alloy steel
Aluminum alloys
Titanium alloys
Inconel
Nickel-based alloys
Copper
Brass
Cast iron
What coolant pressure is commonly used for TSC?
Typical pressure ranges include:
20–30 bar: General drilling and milling
40–70 bar: Medium-depth drilling and demanding machining
70–100 bar: Deep-hole drilling and high-performance applications
100 bar and above: Specialized aerospace, medical, and precision manufacturingThe optimal pressure depends on the cutting tool, material, and machining process.
Can TSC be used with standard tool holders?
Not always.A Through-Spindle Coolant system requires compatible components, including:
TSC-compatible spindle
Sealed tool holders
Through-coolant cutting tools
High-pressure coolant pump
Appropriate rotary unions and sealsStandard tool holders without internal coolant passages cannot deliver coolant through the tool.
What filtration level is recommended for TSC?
High-pressure coolant systems require clean coolant to protect pumps, seals, and cutting tools. Filtration between 10 and 25 microns is commonly recommended, depending on the application and machine manufacturer.
What maintenance does a TSC system require?
Routine maintenance includes:
Cleaning or replacing coolant filters
Checking coolant concentration
Inspecting the high-pressure pump
Monitoring coolant pressure
Inspecting rotary union seals
Cleaning the coolant tank
Removing chips from the filtration systemChecking hoses and fittings for leaks
Can an existing CNC machine be upgraded with Through-Spindle Coolant?
In many cases, yes. Retrofitting depends on the machine’s spindle design, coolant plumbing, and controller compatibility. Many machining centers can be upgraded with a high-pressure pump, rotary union, and compatible tooling.
The function of the tool magazine is to store cutting tools and, in coordination with the CNC system, automatically change tools, thereby completing complex machining.
The tool is a key link in automation; a machining requirement can hardly be fully machined using only one tool. In a fast-paced machining process, automatic tool changing can reduce a massive amount of time cost and greatly improve efficiency.
Do I need a tool magazine?
In areas where 100% precision is required and low failure rates are needed, a tool magazine is not necessarily a mandatory option, because the tool magazine itself may bring a tiny bit of failure rate. For making molds, some master operators do not care about the few minutes of timeliness brought by automatic tool changing; what they care about is that every step needs to be inspected to prevent errors. Under this circumstance, having no tools results in a lower failure rate.
When complex parts machining is required and efficiency needs to be improved, then a tool magazine is indispensable. Tool magazines often come with an automatic tool changing function, and the cumulative efficiency can be improved by a lot.
Suitable for CNC engraving and milling machines, with conventional specifications of 8, 12, and 16; the tool change speed is relatively slow, making it economical and practical.
