Code LSG.01
The Lubrorefrigerator model LSG.01 is specifically designed for use on band saws, disc saws for light alloys, and all machines that need to lubricate and cool the tool and workpiece at a well-defined point. This is achieved thanks to the special cylindrical delivery nozzle with a diameter of only 4mm, making it suitable for insertion into a dedicated hole. The device performs the dual function of minimal cooling and lubrication by supplying small quantities of lubricating fluid carried by the continuous flow of compressed air. Depending on the version, the console has one or more micrometric flow regulators for air and oil, allowing for a variable flow of the air-lubricant mixture.
The device, using the well-known “Venturi Principle,” draws the fluid from the reservoir and mixes it with compressed air inside the terminal element, where the flexible delivery tube is introduced. This tube then conveys the air-oil mixture to the actual cylindrical delivery nozzle.
The LSG.01 family consists of two versions, designated type A and B, differing in their standard equipment and the configuration of the mixing unit (hereafter referred to as the Console). Both are offered with the same delivery tube in single or double nozzle versions. The single nozzle version is typically used on band saws (see photo above), while the double nozzle version is suitable for use on high-speed disc saws (e.g., for light alloys), where it is essential to deliver the lubricating fluid on both sides of the blade.
A fundamental characteristic common to all OilJet products is that careful design, combined with the use of high-quality components, allows for adjustments ranging from the most micrometric, without the formation of annoying aerosols, to those with a significant supply of lubricating fluid.
All models use the Venturi principle, so the fluid is drawn from the reservoir and then mixed with compressed air. This is done in a different way between the two macro-families: LMG01 +01, compared to LTS.02. The end result is very similar, with more or less pronounced predispositions towards certain uses, as described below.
They are designed to use all commonly known lubricating fluids indiscriminately, as described below. They do not provide for the collection and reuse of the used fluid, as the modest quantities dispensed partially deposit on the workpieces, helping to protect them from oxidation, evaporate spontaneously, and partially disperse among the processing waste. The recipient machines are those described in the various technical sheets of each model, extending to special machines and various equipment for mechanical processing. In fact, based on the characteristics of a specific “special machine,” it is possible to opt for one or the other model.
As clearly defined in their respective user and maintenance manuals, for safety reasons and overall consistency, OilJet products are not intended to replace the original continuous fluid cooling system. Beyond certain limits of capacity and severity of certain machines, the performance guaranteed by minimal systems (MQL) would not be sufficient to dissipate the heat generated between the tool and the workpiece.
In conclusion, the ideal recipient machines for installing these products can be defined as belonging to the categories: “chip-removing machine tools and small to medium-sized deformation machines.” For clarity, deformation machines (which are certainly less known) are those that perform their work by “deforming” the metal, such as presses in general and profiling plants.
Where the type and size of the hosting machine allow, OilJet products enable the removal of the old continuous fluid cooling system, with evident advantages in terms of bulk, stagnation of degraded fluids (especially in cases of sporadic use) and consequent disposal, general cleanliness of the surrounding environment, and greater protection of the plastic shields of safety guards.
Each model is developed with a concept of maximum modularity (most additional kits and spare parts are common to all OilJet models). This general flexibility also allows for the development of custom-made products, especially for installations on series machines.
SOME EXAMPLES OF USE:
Example 1: For a vertical spindle machine (e.g., Drill-Milling Machine) that requires frequent tool changes, with probable variation in its own length, the LTS.02 model is preferred, as it is equipped with a “joint” at the base of the flex tube for quick disengagement of the work area, as well as having a friction-type axial adjustment (common to other models). All this results in maximum versatility and speed of use.
Example 2: For a machine with a delivery point distant from the optimal operating point, or to be placed at a distance for safety reasons, the LMG.01.C model is recommended, as it has a satellite nozzle version, that is, detached from the console and supported by its own magnetic base. With the addition of the magnetic base kit for the console support, maximum versatility is achieved.
The classic recipient machine for the LMG.01.C model is the classic Parallel Lathe, as demonstrated in the general presentation video of the OilJet range.
Example 3: For an occasional use machine, on which it might be inconvenient to permanently fix a unit, the most suitable model for the specific case could be used, combined with the optional magnetic base kit, applicable to all OilJet models.
CHARACTERISTICS OF THE MOST COMMON USABLE OILS
Water-miscible oils (also called emulsifiable), whether of mineral, synthetic, or semi-synthetic origin. These lubricating fluids are the most well-known because they are already used in classic continuous jet systems. The fact that all mechanical workshops normally already have this product, besides being the most economical, leads to a prevalent preference for its use.
This product is preferred and recommended by us for use on all OilJet devices, as being water-based, it is less prone to the formation of respirable mist-aerosols.
Neat oils (to be understood as not diluted with water). These lubricating fluids are specially produced for use in MQL (Minimum Quantity Lubrication) systems, a category that includes OilJet products. These are usually of vegetable origin, non-toxic, very fluid, and almost colorless.
As it is a neat product, with equal lubrication and cooling capacity, the quantity dispensed must be significantly lower than the previous one, as its higher viscosity (compared to water) automatically serves this purpose. The technical table present on each product sheet demonstrates this comparison.
It should be noted that this category of products is atomized even at low air flows, making it more difficult to reduce aerosol emissions to zero.
