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

• f 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
• ptimal rigidity in clamped position
• pen for all interfaces

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

Clamping product-CyTool

Whenever only a limited number of tool changes are required, the CyTool is an extremely efficient alternative to the fully automatic changeover systems CyTwist.

Cylinder Technology-CyLock

In modern production, hydraulic and pneumatic cylinders are standard for linear stroke movements. When guaranteed rigidity under load and failsafe function is required the CyLock cylinder with positive locking is the right choice. Due to its positive locking at the end of stroke, many interesting and easy technical solutions are possible. The cylinders enable a considerable simplification of complicated conventional construction. No additional mechanic or steering is

• required. The positive locking automatically becomes effective when the cylinder

reaches the lockable final position. It remains locked even when the pressure is

• disconnected. Since the holding force in the locked position is many times that
• f the cylinder's hoisting power, high counterforce can also be safely absorbed.
• The main benefits are:
• reduced construction-, cost- and production effort
• less parts leading to higher reliability
• longer productive cycles

Cylinder Technology-CyPull

Locking Core pulling Cylinders(HS/HD/HX)

• positive locking
• holding forces of up to several hundred kN
• very rigid construction
• guarantees high product quality
• series HS with preload to compensate in critical cases

elasticities and tolerances of the tool

Cylinder Technology-CyBlock

CyBlock short stroke cylinder

The compact series CyBlock was especially developed for injection moulding cores in tool and mould manufacturing which require a safe holding with only a short mould release stroke. They are easy to mount and to adjust and complete the range

• f the locking cylinders series CyPull. Similar to series CyPull, the CyBlock cylinders

are equipped with integrated positive lock for the extended stroke position of the piston rod. Two versions are available: Series HSZ with positive lock and a locking tolerance range and can be adjusted to generate a preload on the core to compensate tolerances and elasticity of the tool. This type is suited for i. e. complex core forms, partially touching cores, paired touching cores, underfloor slides etc. Series HDZ with positive lock without preload in the end position. This type is suited for i. e. simple core pins, support cylinder for inserts, cores where the use of preload is undesirable.

• very compact construction
• high through-flow speeds
• extremely low flow-resistance
• minimum losses through leaks (Clean Break)
• automatic alignment error compensation(2°, +/-0.5mm, 0.3mm)
