Sealing system

The motor spindle is protected by a labyrinth and sealing air against the ingress of foreign bodies such as chips and
liquids. The IP protection class specified under
and the required flow rate.
3.9

Tool clamping system

The tool change is done pneumatically. By applying the appropriate compressed air, a spring assembly is operated
inside the motor spindle and the collet is released, the tool can be removed. When venting the pneumatics, the
collet is pulled back by the spring assembly and the tool is clamped. The pneumatic system automatically reset
when vented, no separate control or connection is necessary to clamp the tool.
3.10

Collet stop (CS)

By using a defined collet stop the adjusting process for adjusting the axial stroke of the collet-chuck is not needed
(see also Inserting the collet-chuck).
3.11

Taper cleaning (TC)

The taper cleaning protects the area of the shaft cone and collet-chuck from penetration of foreign particles during
the tool change. Due to a suitable valve, taper cleaning is automatically activated with every tool change. No
separate control or connection is necessary.
3.12

Clamping of the motor spindle

The motor spindle has integrated cooling channels for external tool cooling. When using the external tool cooling
(spray nozzles), no further cooling is necessary. For dry machining, the spindle must be cooled via the clamping
bracket.
• Other types of cooling are possible (air or convection). The temperature at the housing of the spindle
should not exceed 60 °C, otherwise the service life of the ball bearings will be shortened.
• If cooling via the clamping device is not sufficient, please contact your SycoTec contact person to check
alternative solutions.
3.12.1 Clamping bracket
SycoTec recommends the use of the water-cooled clamping bracket 4846 (see 2.2 Accessories). The tightening
torque of screws, on clamping device 4846, is 3.0 Nm.
If it is necessary to design clamping bracket by yourself, please note the following points:
• Use a material with good heat conductivity (e.g. aluminum).
• If possible, clamp spindle over the entire clamping range (see
• To ensure equal tensions in spindle housing your clamping bracket must be slotted over the entire length.
• The clamping surface of the clamping device must have a cylindricity < 0.01mm.
• Existing radial venting and leakage bores must not be closed by the clamping device.
• Avoid excessive clamping force (affects the motor spindle's runout and lifetime).
• Contact your SycoTec representative before or after design of the clamping bracket to check the design and
specify the tightening torque of the spindle clamp.
