4 INFORTION FOR SIGNRS OF CIN TOOLS ORTING RINCILS OF ROTTING UNIONS dvantage of Through-Spindle Coolant (TSC) Nearly all modern machine tools and machining centers are equipped with so-called flood coolant. igh-speed cutting tools require both cooling and lubrication to reduce the rate of tool wear and to prevent overheating, which degrade the tool s strength. Flood coolant systems spray coolant fluid onto the work piece near the cutting tool. ut for many machining operations, such as milling or hole drilling, these systems are less effective at getting coolant fluid to the cutting edge. Without coolant, the flutes of the cutting tool can become packed with chips and the cutting edge loses hardness due to overheating. This leads to excessive wear and short tool life. oor chip removal also can cause a poor surface finish on the work piece. In machining centers with through-spindle coolant (TSC), coolant fluid is conducted directly through the cutting tool to cool the cutting edge, reduce friction, and remove chips. Coolant flows axially through a rotating union into the spindle and tool holder directly to the heat source. Compared to flood coolant systems, TSC pays for itself in terms of lower operating costs for tools and coolant. etter control of tool overheating also allows faster feed rates and higher productivity. Flood Coolant Through-Spindle Coolant ow Rotating Unions Work rotating union is a precision mechanical device used to transfer coolant fluid or media from a stationary source, such as a pump, into a rotating device, such as a spindle with cutting tool. The typical coolant fluid is water-based, consisting of approximately 85-95% water for cooling, 2-12% oil for lubricating the cutting edge, and a small amount of other chemicals for keeping the water and oil mixed and for other purposes. ULIN Rotating Unions also can transfer air/oil mist, known as inimum Quantity Lubrication (QL), cutting oils, and even dry air. The exact capabilities vary by model number, so please consult the product pages of this catalog for details. In certain machine tool applications, rotating unions also are used to transfer hydraulic fluid or air for clamping or sensing. arts of a Rotating Union Spindle earings ousing s shown in the picture above, a typical rotating union consists of a rotor that spins at the same speed as the machine tool spindle, a non-rotating element that closes precisely against the rotor, a housing that connects the supply hose to the non-rotating element, and seals that contain the coolant fluid. earing-supported unions connect the rotor to the housing with one or more bearings. earingless unions omit these bearings. epending on the application, the housing may have one or more drain connections. Seals are the heart of the rotating union. They must contain very high pressures while rotating at very high speeds. t 20,000 rpm, for example, the seals of a ULIN 1129 series coolant union are moving at a relative speed of nearly 16 feet per second (5 meters per second), while containing 2030 psi (140 bar) of fluid pressure! icro-lapped ULIN seal For positive sealing, smooth rotation, and long service life, all ULIN seals are micro-lapped with proprietary machines and compounds to achieve an optical flatness of 2 light bands (23 millionths of an inch, or 0.58 microns). In addition, all ULIN coolant unions use seals made from special grades of silicon carbide. ULIN seals therefore have superior resistance to wear and heat accumulation, compared to lesser materials. Finally, ULIN Rotating Unions are designed with balanced mechanical seals. With this technology, seal contact pressure and thrust load on the spindle are minimized, regardless of operating pressure. This reduces seal wear even further, resulting in longer life and more reliable performance. ULIN alanced echanical Seal artial line pressure is applied to seal face.

ULIN makes two different mounting styles. The rotor-mounted style attaches to the machining center with a threaded rotor. The bore-mounted style slides into a precisely machined counterbore at the end of the spindle. second advantage of both styles is that any leakage is channeled by the housing into a drain line. third advantage is that rotor-mounted, bearing-supported unions absorb nearly all axial forces (thrust load) on the spindle caused by coolant pressure. For both bore-mounted and bearingless unions, however, coolant pressure creates a certain thrust load on the spindle. earing or earingless? earingless unions provide the machine tool designer with several advantages. First, eliminating bearings reduces cost while allowing an increase in maximum rpm. Second, since only a small rotor is directly attached to the spindle, there is no possibility for the union s housing to be a source of vibration. Third, without bearings the union is immune to side loading from, for example, too much tension in the coolant supply hose. Fourth, bearingless unions can be very small, ideal for applications with multiple, closely spaced spindles. owever, bearingless unions must be installed in two pieces the rotor and a small housing containing the non-rotating element and connection to the coolant supply. So, during installation, the micro-lapped seal faces are exposed and must be handled carefully.

6 INFORTION FOR SIGNRS OF CIN TOOLS SLCTING T RIGT UNION FOR YOUR LICTION Which ULIN Seal Technology? ULIN offers five different seal technologies, in order to provide the best solution for every machining application. Only ULIN can offer such flexibility to the machine tool designer. Closed Seal: s the name indicates, the seals stay closed with or without coolant pressure. Therefore, drain lines generally are not required. owever, all rotating unions operate with a thin film of media between the seals. Over time, small, nearly invisible quantities of media can migrate across the seal faces. Therefore, proper venting provisions should be made. Closed seal unions generally are less affected by extremely contaminated coolant than other designs. owever, closed seal unions should not be rotated for an extended time if coolant fluid is not present. Controlled Leakage: The opposite of closed seals, controlled leakage seals always have a small gap between the seals, even when pressure is applied. For this reason, controlled leakage unions are excellent for high-speed applications with pressurized dry air. Controlled leakage unions generally are not suitable for coolant fluid applications. op-off T : This kind of seal closes only when pressure is applied. When pressure is removed, the seal faces separate by a very small distance. This eliminates friction and seal wear during operation without coolant, and therefore allows unlimited dry running at high speeds. op-off T designs should be considered when machining will occur with and without through-spindle coolant (TSC). ecause the seals separate during tool changes when coolant pressure is off, residual coolant in the supply hose and spindle can drain through the seal faces. Therefore, a op-off T union generally requires a downward-pointing drain line to direct such residual coolant into the sump. lso note that op-off T unions are not intended for extended operation with pressurized dry air. utosense T : The latest in a series of ULIN innovations, this technology combines the best features of op-off T and controlled leakage designs. Like op-off T designs, utosense T seals close when coolant pressure is applied to contain the coolant fluid, and pop apart in the absence of coolant pressure to allow unlimited dry running. Like controlled leakage designs, utosense T seals handle pressurized dry air by creating a microscopic gap between the seal faces. utosense T unions handle coolant, QL, and dry air by sensing the kind of media and automatically changing seal operation in response. s with op-off T seals, a drain line generally is required. ll-: This technology gives the machine designer complete control over seal opening and closing. y controlling how the pressure is applied to the union s multiple connections, the machine designer can cause the seals to separate when necessary (for example, to transfer pressurized dry air) or close when appropriate (to transfer coolant fluid or oil mist). drain line generally is required.

8 INFORTION FOR SIGNRS OF CIN TOOLS RIN N SULY OS CONNCTIONS rain ll unions, even closed-seal designs, can experience migration of minimal amounts of media across the seal faces. Such media migration keeps the seals well lubricated and avoids the permanent seal damage that comes from dry running. In addition, even the best unions eventually will need replacement. Therefore, the machine tool designer should provide adequate drainage to prevent costly spindle damage. ULIN designs are very advanced, but even ULIN must obey the law of gravity! Therefore, it is critical that all drainage hoses and paths slope downward continuously, as shown in the diagrams to the right. YS! YS! NO! NO! rain hose always slopes downward rain hose always slopes downward art of drain hose slopes up rain hose slopes up from union Supply ULIN op-off T, utosense T, and ll- unions offer unlimited dry running at high speeds. y allowing the seal faces to separate when coolant pressure is removed, seal wear during unpressurized operation is completely eliminated. One consequence is that the seals separate during tool changes, Supply ose Slopes own From Union allowing residual coolant in the supply hose and spindle to drain through the seal faces. Careful orientation of the coolant supply hose can dramatically reduce this effect, as shown in the diagrams below. Supply ose Slopes Up From Union When the supply line runs down from the rotating union, any coolant between union and control valve will remain in the hose during tool change. This reduces the amount of drainage from both the spindle nose and the union drain line. When the supply line runs up from the rotating union, any coolant between union and control valve will flow down during tool change. This increases the amount of drainage from both the spindle nose and the union drain line.

9 INFORTION FOR USRS OF CIN TOOLS INSTLLTION TCNIQUS Installing a ULIN Rotating Union is as easy as For maximum life and reliability, maintenance engineers and service technicians need only to follow a few simple rules. 1. For bearing-supported, rotor-mounted unions, connect both supply and drain hoses to the union before mounting the union on the spindle. Otherwise, bearings in the union may become brinnelled or galled when the hose connections are tightened. 2. Clean the mounting surfaces of the spindle thoroughly before mounting the union. The spindle pilot must be clean, with no chips, no burrs, and no dents. Otherwise, the union may exhibit runout and vibrate during rotation. 3. ake sure the drain hose runs downward continuously, with no roller coaster rises that could prevent proper drainage. If the spindle is horizontal, make sure that the union s drain hole is at 6 o clock, pointing directly down. unions can do many things, but they can t break the law of gravity! Following are examples of correct and incorrect installations, with an explanation of what is correct or incorrect about each example. xamples of CORRCT Installations YS! YS! YS! YS!

When pressurized, the supply hose may create a large side load on the union s bearings or ULIN 9

10 INFORTION FOR USRS OF CIN TOOLS COOLNT FILTRTION N INTNNC ULIN unions are designed to handle the various coolant contaminants found in most manufacturing facilities. To ensure long union life and maximum productivity, however, coolant filtration should conform to ISO 4406:1999 Code 17/15/12, S 749 Class 5, or NS 1638 Class 8, with a maximum particle size of 60 microns. For comparison, pumps (both fixed piston and variable volume) such as those used in coolant systems typically require ISO 4406 Code 16/14/11 or better in other words, half as much contamination as ULIN. Only pure water should be used to make up for coolant evaporation. Calcium and magnesium salts in most tap water shorten coolant life, by depleting the chemicals in the coolant, by breaking down the water-oil emulsion, and by encouraging bacterial growth. These salts also can cause residue to build up inside the rotating union, leading to premature failure. One rule of thumb is that each additional grain of hardness (equivalent to 17 ppm or 17 mg/l of calcium carbonate) increases your annual coolant consumption by one percent. roper coolant maintenance also prolongs tool life and improves the surface finish of your parts.

There are no warranties which extend beyond the description contained under this heading, express or implied, including warranties of fitness for a particular purpose. Important Notice The ULIN Rotating Union is a precision-made piece of equipment and should be handled accordingly. It is a rotating sealing device not just a plumbing union. Improper use or installation can result in premature leakage or failure. While ULIN unions are of the highest quality and precision, they are wear and tear items. It is important that they are periodically inspected and, as the seals wear out, replaced or repaired to avoid the consequences of leakage. ULIN unions never should be used for applications other than as specified in the catalog. ULIN unions should not be used to convey flammable media (flash point 140 F or 60 C) as leakage may result in explosions or fires. eublin unions should be used in accordance with standard safety guidelines for the media, and in a well-ventilated area. The use of our product on hazardous or corrosive media is strictly forbidden. For applications other than as stated in the catalog, contact ULIN s ngineering epartment for recommendations. These instructions are provided as general guidelines. They do not contain exhaustive information about the installation, use or maintenance of unions. urchasers and users of ULIN unions should be certain that they have reviewed ULIN s catalog and have sufficient experience and training in the use of unions before attempting installation or use of ULIN products. The principal responsibility for the safe and effective use of ULIN unions rests with the user and its employees. ULIN will provide, upon request, whatever assistance it can to advise users about the use of its products and about any difficulties or problems which are brought to its attention. Factory Testing ll ULIN Rotating Unions are factory-tested under pressure prior to shipment. This thorough check ensures that each ULIN union performs as intended. ULIN Rotating Unions can be installed with the confidence that they will operate to your complete satisfaction. contact ULIN at or ULIN 41
