The Development Increase of power and torque Improvement of the axial and radial stiffness HV-X -/ HV-X -/ Axial Stiffness Radial Stiffness HSX -/ HSX -/ HS -/ HS -/ TSSV -/ TSSV -/, torque and stiffness have been constantly increased as the tables indicate. In addition, reliability, load carrying capacity and working life were also improved. The working life of HSX-spindles in comparison to the HS-spindles is on average times longer. Economical With the improvements of power, load carrying capacity and stiffness in the HV-X designs the working range of single spindles is extended over the previous models. These enhancements minimize the number of spindles required to cover a large speed range. The special motor design also permits the use of more economically sized frequency converters to match the application requirements. Selection The GMN product line covers a vast range of speeds, output powers, load capacities and options to meet or exceed all application requirements. Tradition GMN strives to provide it customers with the latest advances and technology in spindle design and concepts. With our "Customer First" mentality we will continue to manufacture our traditional style spindles, components and provide service and support for the older models and designs.

Advantages Of Hybrid Ceramic Bearings GMN high frequency spindles utilize hybrid ceramic ball bearings. These bearings have standard steel bearing races and are matched with silicon nitride balls. Advantages of hybrid bearings compared with normal spindle bearings are: Reduced wear The high degree of hardness of the balls, and the nongalling effect of the silicon nitride against metallic material lessens the wear. This is especially important in cases of minimal lubrication. In addition, wear particles will not embbed themselves into the balls to further damage the races. Rigidity Modulus of elasticity is greater than steel, which increases the static and dynamic stiffness. The increase in dynamic rigidity depends on the ratio of bearing preload to the centrifugal force on the balls. Friction Because of the reduced spin-rolls ratios and lower Hertian stresses, friction and respectively operating temperatures are reduced. Axial shaft movement As a result of the lightweight ceramic balls, centrifugal forces are reduced with a corresponding reduction in dynamic movement of bearing races. In addition, movements due to less friction and the lower coefficient of expansion of ceramics are reduced. Reliability of operation The low thermal coefficient of expansion of the ceramic balls lessens the reduction of the radial running fits in the bearings. These fits are less variable at higher temperature differentials between races. Vibrations Radial forces and the moments acting on the bearings produce displacement between the balls and the retainer. Hybrid bearings reduce this effect and produce a positive influence on cage vibrations and stresses. Accuracy High frequency spindles are fitted with bearings produced according to GMN standard grade UP. They are distinguished from international standards due to excellent running accuracy.

Chip removal processes are defined by the material being processed, tool sizes and recommended cutting speeds. Small diameter tooling requires high speeds, while large diameter cutters need high torque at lower speeds. The "field weakening" characteristics offer high torque at low speeds and are also capable of high spindle speeds utilizing the same spindle. Therefore the spindles can be operated with smaller converters at different levels. The capacity of the converter determines the power profile. The output power of the motor is produced via the converter being programmed to the proper volts/frequency [v/f] ratio specified in the instruction manual or test report of spindle. Operation with reduced output power up to various speeds Drehzahl / Speed Rigidity required for the volume of material to be removed and also provide a quality finish, this demands larger shaft diameters, thereby spindles become, which allows for longer and more powerful motors. Because of progress in the development of motors, the power density has been increased to such an extent that, in many cases, the power which can be produced from these proportions is not need for processing. On the other hand, oversized systems cause increase costs because of the size of the frequency converter which are required. Operation mode S and S-% Operation mode S Nominal power No-load Operation mode S-% n I Drehzahl / Speed Costs of frequency converters can be reduced by accepting the decreased output power and possibly lower frequency. n II maximaler sbereich maximum power range reduzierter sbereich reduced power range Nominal power No-load sec 7 sec Total time = minutes Drehzahl / Speed

Safety Aspects For Tool Selection Unbalanced state Every spindle shaft and every tool incorporates a degree of unbalance, which causes sinuous vibration during rotation. To reduce the effect of unbalancing forces, the unbalancing mass of all rotating parts has to be limited. Shafts of GMN high frequency spindles are always balanced. As a result of higher cutting speeds this process is also required for tools. We recommend for precision cutting a permissible residual unbalance for tools according to the following diagram: We recommend consulting our application engineering staff when tools which are extremely long and heavy are to be used. Let GMN analyses your spindle and tooling requirements with our specifically designed computer software. In addition to the critical frequencies the static and dynamic stiffness and load carrying capacity of each single bearing can be calculated. Through proper analysis the correct spindle can be selected or tips for improvement of tools can be made. Permissible residual unbalance [gmm] 7 Grease lubricated spindles Oil/air lubricated spindles Operating speed [rpm] GMN Calculation program WINSPI Critical speed GMN high frequency spindles are designed so that the critical speeds remain above the maximum speed. When using inappropriate tooling the critical speed can be decreased to a level within the operating speed range. This can lead to poor part quality, decreased spindle performance, as well as jeopardizing the safety of the operator and machine. Centrifugal forces acting on tools Centrifugal forces created by high rotating speed not only act as unbalancing forces but also induce stress into the tool. Especially inserted tooth milling cutter are very dangerous. When the attachment fails, indexable inserts can fly away like projectiles.

HSK Style Interface "Hollow tapered shanks with flat contact surfaces" are standard per DIN 99. The different "FORM'S" of a particular size are based on a similar shank size (d) dimension. The tool flange is dictated by the mode of tool change. HSP/HV-P style spindles allow the use of tools with short hollow shanks, type "A" and "C". Form "C" was developed specially for manual tool changing systems. Form "A" is distinguished by the "V" groove provided for automatic tool changing systems. Form "A" can also be used with the manual tool change system provided in the HSP/HV-P style spindles. This reduces the need for additional tool holders if automatic tool changing systems are already in place. Tools according to Form B, D, E and F cannot be used in the HSP/HV-P style spindles, they are designed for different applications.

Compressor M Level indicator Eva porator Water reservoir Temperature controller Refrigerant circulation: u Cool refrigerant gas is pumped out of the evaporator/heat exchanger by the compressor and compressed into a high temperature, high pressure gas and delivered to the condenser. u In the condenser the gas condenses into a liquid as it dissipates heat to the air being blown across the condenser fins. u The cooled, high-pressure liquid refrigerant then passes through the expansion valve to the low-pressure side of the evaporator. The refrigerant absorbs heat from the coolant passing through the evaporator as it changes from a liquid to a gas. Parallel connection: u Multiple spindles operating from a single chiller unit. u Spindles of different sizes, cooling and flow requirements should be connected in parallel. u It is important to select the correct chiller with sufficient cooling and flow capacity for all the spindles being used. u Individual flow monitoring units are required for each cooling loop. Series connection: u Multiple spindles operating from a single chiller unit. u Spindles of the same sizes, cooling and flow requirements should be connected in series. u Do not plump more than two () spindles in series. u A single flow monitoring unit is required for a series setup and mounted at the end of the run.
