CyTec Systems is a German multinational company that serves the market with high-tech fabrication Machine parts. For over 30 years, CyTec has been developing and producing components, such as cylinders, clamping systems, motor spindles, milling heads, trunnion and rotary tables at the highest standards. CyTec Systems was founded in 1984 as a specialist for locking cylinders. It continuously advanced and established itself in the range of machine and tool clamping technology. With the introduction of the HSK tool interface in 1994, CyTec in cooperation with a well-known German machine tool manufacturer created motor spindles as a new product range. This was the basis for the setup of CyTec’s core competencies as a manufacturer of motor spindles. In 2002 the first two axis fork milling head with torque motors as direct drives was presented. This technology can be found in more than thousand rotating machining axes to this day. Today, CyTec is one of the biggest German milling head producers, operating in the industry over 30 years. The CyTec patent on the milling head technology has set the direction on the market for high-end milling head technology. CyTec’s innovative products offer a wide range of two axis fork style milling heads to perfectly match your application requirements. CyTec provides the highest quality of components such as bearings, rotary unions, swivel brackets, axis clamping and energy couplers designed and produced in house. CyTec is proud to offer you our expertise and superior quality products!

CyTec spindle structure Clamping system(CyTwist) Rotary union Bearing Cooling circuits Minimal quantities of lubricant Gear spindle Monitoring
CyTec spindle structure-Rotary Union Clamping and releasing tool CyTwist clamping system is self locked .the rotary union doesn't have to and must not be held under hydraulic pressure. means that reduction of the initial tension is possible during operation at the high speed without causing a leakage which may damage the spindle bearings. The seals combination allows circumferrential velocities leading up to 50 m/s, means the rotary unions can work with contacting seals leakage- free at least up to 30,000 r.p.m.
Rotary union cooling Internal coolant flow A permanent contacting ceramic axial face seal ring can be used up to 80 bar and a speed of 24,000 r.p.m.. A loss of the rotary union or a leakage are prevented. This technology has proved itself for several years of experience. Recirculating cooling With low pressure (» 1 bar) a recirculating cooling is achieved by the closed check valve. Therefore the internal coolant is equipped with two connections. This technology guarantees balanced thermal values for dry as well as for wet operation.
CyTec spindle structure--Bearing Hybrid-bearings for highest spindle rigidity, load bearing capacity, accuracy and service life The front of the spindle is equipped with a triple tandem-o hybrid bearing and is preloaded hydrostatically and by spring pressure. On the rear the bearings are preloaded by springs in tandem position. Lubrication of bearings Depending on the speed range the bearings can be lubricated with grease or oil- air. The economic lifetime grease lubrication is suited most of all for low and intermediate speed ranges. Oil-air lubrication allows highest speed ranges. It is directly injected into the most highly-stressed bearing zone. Even with highest speed loads an optimal life service is ensured. This bearing concept guarantees highest machining precision with minimal spindle expansion.
Spindle cooling circuits Circuit spindle cooling The spindle cooling circuit prevents the growth of the spindle to the front and protects the bearings. The temperature remains constant independently from the speed. There is no influence on the spindle's accuracy. Circuit motor cooling The dissipated heat of the motor is derived by the motor cooling so that the temperature of the spindle housing can be held on ambient level.
Tool cooling circuits The tool cooling can optionally be achieved either as external coolant and/or internal coolant flow supplied through the rotary union. ECS ICS
Minimal quantities of lubricant (MQL) Advantages over full cooling: -No disposal costs for the cooling medium -Cost savings due to limited lubricant consumption -No cooling system is required Oil and air Mixed inside spindle Oil and air mixed before go inside
Gear spindle(1:3) • The two basic advantages of this design are: • Problems due to too low torque in the lower rotational speed ranges are eliminated. • The machining centers design is simplified with regard to the spindle head. This allows a high- speed machine to be used in the stand-alone sector since there is no need for other machines to provide higher cutting forces. Therefore set-up and investment costs are reduced.

Clamping product-CyDock CyDock docking system guarantees the ultimate in precision and safety using simple technology. A coupling bolt is automatically positively locked by means of radialy operating locking segments. This is done free from play on demand. The coupling is released by applying hydraulic or pneumatic force. Holding forces of up to several hundred kN can be achieved. CyDock is suitable whenever secure connections have to be made and released as easily as possible.
Clamping product-CyDim The success of the design of the CyDim lies in its simplicity. As a universally applicable connecting element, it is capable of meeting nearly all demands of flexible production systems. The CyDim can be operated hydraulically or pneumatically. Using simple methods it fulfills the three most important functions of clamping technology: • Very high forces while using minimum space(300kN) • Self-retention of the clamping force without maintaining pressure • Low clamping and release pressure
Clamping product-CyTrack The previously described advantages of the CyDim are dramatically enhanced by the actions of a positively locked collet coupling, making it possible to realize the total functions Couple - clamp - lock with only one element and without any need of additional control requirements. The system also could be named "the automatic screw".
Clamping product-CyTab Pallet clamping system for indexed pallets in rotary milling machines For precise clamping of pallets in rotary milling machines CyTec offers a universal clamping system based on the CyTrac collet clamp lock. This system has proved popular due to its high clamping forces and system rigidity. As a result, high levels of reliability and operational safety are guaranteed. The CyTab is self-locking and makes a strong coupling that is shielded from the highest effects of vibration.
Clamping product-CyTwist • rotational symmetry • high clamping force • HSC eligibility • optimal rigidity in clamped position • open for all interfaces • high pulsed release force • safe locking The CyTwist easily fulfills the three main functions of clamping technology: • Highest clamping forces whilst using minimum space • Self retention of the clamping forces without maintaining pressure • Low clamping and release pressure
