Marvell EasyCut 68 Non-Emulsifying Cutting Oil 20L

Product Description

Marvell EasyCut 68 is a heavy, transparent, non-emulsifying cutting oil developed for machining ferrous metals in applications that specifically require a high-viscosity neat oil. Its ISO VG 68 viscosity provides a substantial lubricating film between the cutting tool, workpiece and chip, helping reduce friction and support consistent machining under suitable operating conditions.

The product is intended for specialised cutting operations where a lighter cutting oil may not provide the required oil-film thickness or retention. Its relatively heavy viscosity allows it to remain at the cutting interface and provide sustained lubrication during compatible low-speed or high-contact machining processes.

Marvell EasyCut 68 is supplied as a neat or straight cutting oil and must be used undiluted. It is not designed to be mixed with water or operated as a soluble, semi-synthetic or fully synthetic water-miscible coolant.

The term “non-emulsifying” means that the product is formulated to resist forming a stable emulsion with water. If incidental water enters the machine sump, the oil and water are intended to separate rather than remain permanently combined. This separation can make water contamination easier to identify and remove.

Non-emulsifying performance does not mean that water contamination is acceptable. Water can promote corrosion, support microbial growth in accumulated contamination and reduce lubricant performance. Free water should be drained or removed from the machine system as soon as practical.

The transparent appearance of Marvell EasyCut 68 helps operators observe the workpiece, cutting tool, chip formation and oil delivery. The product remains a heavy oil, however, and its high viscosity can affect circulation, cooling, chip transport and pumping resistance. It should therefore be confined to equipment and operations where an ISO VG 68 cutting oil is specifically required or has been proven suitable through a controlled machining trial.

Marvell EasyCut 68 is intended primarily for ferrous-metal machining. Ferrous metals are materials based principally on iron, including compatible carbon steels, alloy steels and cast irons. The precise suitability depends on the metal composition, hardness, machining method, tool material, cutting speed, feed rate and required finish.

The product should not automatically be used on brass, copper, aluminium or other non-ferrous metals. Cutting-oil chemistry that performs effectively on ferrous metals may stain or otherwise affect sensitive non-ferrous alloys. Use Marvell Easy Cut 111 or another appropriate inactive cutting oil where non-ferrous-metal compatibility is required.

Not every operation listed will necessarily require ISO VG 68. The correct product must be selected according to the equipment, workpiece and tooling requirements.

A high-viscosity cutting oil may not be appropriate for very high spindle speeds, small oil passages, mist-lubrication systems or equipment fitted with pumps designed for low-viscosity fluids. Excessive viscosity can restrict flow, increase pump load, reduce heat transfer and interfere with chip removal.

Marvell EasyCut 68 should not automatically be used for high-speed grinding. Grinding applications generally require excellent cooling, rapid chip removal and effective filtration, which may be better provided by a lower-viscosity grinding oil or water-miscible fluid.

The product should also not be used as a substitute for hydraulic oil, slideway oil, spindle oil, gear oil, quenching oil or general-purpose circulating oil unless the equipment manufacturer specifically permits its use.

Key Features and Benefits

Heavy ISO VG 68 Viscosity

Marvell EasyCut 68 provides the viscosity required for compatible metal-cutting operations where a heavy oil is preferred.

Its substantial oil film helps maintain lubrication across the cutting tool, workpiece and chip. This can be beneficial under slow-speed, high-contact conditions where a lighter oil may drain away too rapidly.

The higher viscosity also helps the product remain on exposed tools and vertical surfaces longer than a very light cutting oil. This can support sustained lubrication during suitable manual and machine operations.

Strong Lubricating-Film Retention

Machining exposes the cutting fluid to pressure, heat and mechanical displacement. If the fluid cannot remain at the cutting interface, friction and tool wear may increase.

Marvell EasyCut 68 is designed to provide a persistent lubricating film. Its heavy viscosity helps resist rapid displacement from the working area and supports separation between contacting metal surfaces.

The product cannot compensate for damaged tools, excessive cutting speed, incorrect feed rate, inadequate machine rigidity or unsuitable tool geometry.

Non-Emulsifying Performance

Water can enter a cutting-oil system through condensation, leaking coolant systems, cleaning operations or contaminated workpieces.

Marvell EasyCut 68 is formulated to remain separate from incidental water rather than forming a stable emulsion. Once the machine is allowed to settle, free water may collect at the bottom of the sump, where it can be identified and removed.

Routine sump inspection remains important. Water should not be allowed to accumulate because it may encourage rust, interfere with lubrication and transport contamination through the machine.

Transparent Appearance

The transparent oil supports visibility of the cutting area. Operators may be better able to observe tool engagement, chip formation, workpiece position and oil coverage than when using a heavily coloured or opaque cutting product.

The oil must still be kept clean. Fine metal particles, oxidation and contamination can progressively reduce transparency during service.

Ferrous-Metal Machining

Marvell EasyCut 68 is specifically directed toward ferrous-metal machining. Its performance profile is intended for iron-based materials under conditions requiring a high-viscosity neat cutting oil.

Different ferrous materials vary substantially in machinability. Free-cutting steel, carbon steel, hardened alloy steel and cast iron may require different tooling, speeds and lubrication.

A controlled trial should be performed before using the product on unfamiliar alloys or critical components.

Friction Reduction

Friction develops where the cutting tool contacts the workpiece and where the chip moves across the tool face. Excessive friction can increase heat, power demand, tool wear and surface damage.

The heavy oil film provided by Marvell EasyCut 68 helps reduce direct contact across these interfaces. Correct lubrication may support smoother tool operation and more predictable machining performance.

Tool-Wear Control

Cutting tools are exposed to abrasion, adhesion, heat and mechanical stress. Insufficient lubrication can accelerate flank wear, crater wear and cutting-edge damage.

Marvell EasyCut 68 helps protect the tool by maintaining lubrication at the cutting interface. Longer and more predictable tool life can improve production consistency and reduce tool replacement.

Actual tool life depends on workpiece hardness, tool material, tool coating, machine alignment, operating parameters and lubricant delivery.

Surface-Finish Support

A stable lubricant film can help reduce tearing, scoring and built-up material across the cutting edge. This may support a more consistent surface finish on compatible ferrous components.

The final finish must be assessed during production. Correct cutting speed, feed, tool geometry and workpiece support remain essential.

Heat Removal

Although neat cutting oils are primarily selected for lubrication, circulating oil also removes heat from the tool, workpiece and chips.

Because ISO VG 68 is relatively heavy, it generally transfers heat less rapidly than a lower-viscosity oil or water-miscible coolant. Adequate flow and correct nozzle placement are therefore particularly important.

Reduced Run-Off

The high viscosity helps reduce rapid run-off from cutting tools and workpiece surfaces. This can be beneficial during manual operations or intermittent processes where the oil must remain in position between applications.

Excessive application should still be avoided. Surplus oil can increase housekeeping requirements and create slip hazards.

Water Separation and Maintenance

The ability to separate from water can simplify fluid maintenance compared with a product that forms a persistent unwanted emulsion.

Allowing the system to settle may assist with identifying free water. Drain points, sump geometry and maintenance access should be arranged so that collected water can be removed safely.

Suitable for Controlled Manual Application

Marvell EasyCut 68 can be applied with a suitable brush, pump bottle or directed dispenser during compatible manual machining operations.

The applicator should deliver sufficient oil without creating excessive splashing or uncontrolled runoff. Compressed-air spraying should be avoided because it can generate airborne oil mist.

Suitable for Compatible Circulation Systems

The product may be circulated through machine-tool systems designed for ISO VG 68 oil.

Pump capacity, pipe diameter, filtration and nozzle design must be appropriate for the viscosity. A system designed for a very light spindle or grinding oil may not circulate Marvell EasyCut 68 effectively.

Typical Physical Properties

Typical properties represent the supplied product description and standard ISO VG 68 viscosity range. Density, viscosity at 100°C, flash point, pour point, copper corrosion and other numerical properties should be added from the final Marvell Product Data Sheet or representative production-batch results before publication where required.

Handling & Storage Advice

Store Marvell EasyCut 68 in its original, correctly labelled 20-litre container. Keep the cap securely closed and store the container upright in a cool, dry and well-ventilated location.

Protect the product from direct sunlight, rain, excessive heat, ignition sources, sparks, hot work and physical damage.

Do not allow water, coolant, hydraulic fluid, slideway oil, solvent, cleaning chemicals, dirt, dust, swarf or used lubricant to enter the container.

Use clean and dedicated pumps, hoses, funnels and dispensing equipment. Equipment contaminated with water or another metalworking fluid can reduce the product’s non-emulsifying performance.

A full 20-litre container is heavy. Assess the load before lifting and use assisted lifting, team lifting or suitable mechanical handling equipment where required. Do not attempt to lift or carry the full container if it cannot be handled safely.

Avoid prolonged or repeated skin contact. Suitable protective equipment may include oil-resistant gloves, protective clothing and safety glasses, depending on the workplace risk assessment.

Wash exposed skin thoroughly with soap and water after handling. Do not use petrol, kerosene, solvents, abrasive cleaners or contaminated workshop rags to remove oil from the skin.

Machine operations can generate oil mist, particularly at higher spindle speeds or where fluid strikes rapidly moving tools and components. Use suitable machine enclosures, guards and local exhaust ventilation.

Do not use compressed air to blow the product from machinery or components where this could create an inhalation hazard.

Clean spills immediately because a high-viscosity cutting oil can create a serious slip hazard. Contain spilled material using a suitable absorbent and prevent it from entering drains, stormwater systems, soil or waterways.

Used cutting oil may contain fine metal particles, wear debris and other contaminants. Collect it in a suitable labelled container and send it to an authorised recycling or waste-management provider.

Consult the current Marvell Safety Data Sheet before workplace use.

Directions for Use

Marvell EasyCut 68 is designed to be used neat. Do not dilute it with water.

Before initial filling, confirm that the machine-tool manufacturer permits an ISO VG 68 non-emulsifying cutting oil.

Check that the pump, pipes, hoses, filters and nozzles are capable of handling the product’s relatively high viscosity.

Where changing from another cutting fluid, drain and clean the machine sump, pipes and filtration system as required. Remove water, sludge, chips and incompatible lubricant residue.

Fill the machine to the recommended operating level using clean transfer equipment.

Direct the oil flow toward the cutting edge and tool–workpiece interface. The flow must be sufficient to lubricate the contact area and remove heat and chips.

During initial operation, monitor pump load, oil flow, oil temperature, tool wear, surface finish and chip removal.

If oil delivery is slow or inadequate, check the pump capacity, filter condition, hose diameter and oil temperature. Do not assume that increasing the machine speed will improve circulation.

For manual application, use a suitable brush or controlled dispensing container. Apply sufficient oil to maintain coverage without creating unnecessary runoff.

Allow the machine sump to settle periodically and inspect for separated water. Remove free water from the lowest available drain point using an approved maintenance procedure.

Maintain filters, strainers and settling compartments. High-viscosity oil can retain metal particles if filtration and settling are inadequate.

Do not mix Marvell EasyCut 68 with unknown cutting oils, soluble coolant, hydraulic oil or another lubricant unless compatibility has been confirmed.

Inspect the product regularly for excessive darkening, thickening, sludge, unusual odour, water contamination or a decline in machining performance.

Conduct a controlled machining trial before using the product on an unfamiliar metal, new tool or critical production component.
