5 INORTION OR SIGNRS O CIN TOOLS ORTING RINCILS O ROTTING UNIONS dvantage of Through-Spindle Coolant (TSC) Nearly all modern machine tools and machining centres 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. lood 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 swarf, and the cutting edge loses hardness due to overheating. This leads to excessive wear and short tool life. oor swarf removal also can cause a poor surface finish on the work piece. In machining centres with through-spindle coolant (TSC), coolant fluid is conducted directly through the cutting tool to cool the cutting edge, reduce friction, and remove swarf. Coolant flows axially through a rotating union into the spindle and toolholder 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. lood Coolant ow Rotating Unions Work Through-Spindle Coolant 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. U- LIN Rotating Unions also can transfer compressed 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 catalogue 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 rain Seals 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 nonrotating 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 2, 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 metres per second), while containing 23 psi (14 bar) of fluid pressure! icro-lapped ULIN seal or 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.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. inally, ULIN Rotating Unions are designed with balanced mechanical seals. With this technology, seal contact pressure and thrust load on the spindle are minimised, 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 spindle 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 channelled by the housing into a drain line. third advantage is that rotor-mounted, bearing-supported unions absorb all axial forces (thrust load) on the spindle caused by coolant pressure. or 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. irst, 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. ourth, 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. ULIN 1116 earing-supported Unions on utomotive Transfer Line.

7 INORTION OR SIGNRS O CIN TOOLS SLCTING T RIGT UNION OR 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. roper venting provisions therefore 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. or this reason, controlled leakage unions are excellent for high-speed applications with pressurised dry air. Controlled leakage unions generally are not suitable for coolant fluid applications. utosense : The latest in a series of ULIN innovations, this technology combines the best features of op-off and controlled leakage designs. Like op-off designs, utosense 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 seals handle pressurised dry air by creating a microscopic gap between the seal faces. utosense unions handle coolant, QL, and dry air, by sensing the kind of media and automatically changing seal operation in response. s with op-off seals, a drain line generally is required. ll-edia : This technology gives the machine designer complete control over seal opening and closing. y controlling how pressure is applied to the union s multiple connections, the machine designer can cause the seals to separate when necessary (for example, to transfer pressurised dry air) or close when appropriate (to transfer coolant fluid or oil mist). drain line generally is required. op-off : 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 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 union always requires a downwardpointing drain line to direct such residual coolant into the sump. lso note that op-off unions are not intended for extended operation with pressurised dry air. The table below summarises the operation of each seal technology with different media.

8 INORTION OR SIGNRS O CIN TOOLS OUNTING TOLRNCS The interface between spindle and union must be manufactured to precise tolerance to ensure accurate, vibration-free operation. earingless unions and rotor-mounted, bearing-supported unions require the spindle end to be machined according to the following dimensions and tolerances: Table shows reference data: lease refer to the dimensions on the individual drawing when dimensioning the spindle. ilot Spindle nd Tightening I X Y Z Torque 5/8-18 UN 9/16" 15/16".6555" /.6553" 3/16".656" /.6556" 9/32" 13/16" 35 Nm 5/8-18 UN 9/16" 15/16".6249" /.6246" 3/32".6254" /.625" 3/16" 9/16" 35 Nm 16 x / / Nm 16 x / / Nm 14 x / / Nm 12 x / / Nm 12 x 1 / 12 x / / Nm 1 x / / Nm 8 x / / Nm ll dimensions in millimetres unless otherwise indicated.

9 INORTION OR SIGNRS O CIN TOOLS RIN N SULY OS CONNCTIONS rain s 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 below. 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 ose Slopes own 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. ULIN op-off, utosense, and ll-edia unions offer unlimited dry running at high speeds. y allowing the seal faces to separate when coolant pressure is removed, seal wear during unpressurised operation is completely eliminated. One consequence is that the seals separate during tool changes, 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. ose Slopes Up from Union 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.

10 INORTION OR USRS O CIN TOOLS INSTLLTION TCNIQUS Installing a ULIN Rotating Union is as easy as or maximum life and reliability, maintenance engineers and service technicians need only to follow a few simple rules. 1. or 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 thoroughly the mounting surfaces of the spindle 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. ULIN unions can do many things, but they can t break the law of gravity! ollowing are examples of correct and incorrect installations, with an explanation of what is correct or incorrect about each example. xamples of CORRCT Installations YS!

11 INORTION OR USRS O CIN TOOLS COOLNT ILTRTION 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 446:1999 Code 17/15/12, S 749 Class 5, or NS 1638 Class 8, with a maximum particle size of 6 microns. or comparison, pumps (both fixed piston and variable volume) such as those used in coolant systems typically require ISO 446 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.
