Preliminary information Preliminary information The high frequency spindle (HF spindle) is a high quality precision tool for high speed machining. Purpose of the manual The manual is an important component of the HF spindle. Ü Store the manual carefully. Ü Make the manual available to all persons who work with the HF spindle.
Transport and packaging Transport and packaging Avoid strong vibrations or impacts during transportation, as these could dam- age the ball bearings of the HF spindle. Ü Any damage reduces the accuracy of the HF spindle. Ü Any damage restricts the functionality of the HF spindle. Ü...
Designated use Packaging of HF spindle All transport packaging materials can be recycled in appropriate disposal facil- ities. Designated use The HF spindle is an “incomplete machine” in accordance with the Machinery Directive and cannot perform any function independently. The HF spindle can only be operated in conjunction with a machine tool and a frequency con- verter.
Safety instructions Safety instructions The high frequency spindle is a state of the art product and is safe to operate. However, the HF spindle may pose a risk in the following cases: If it is installed by untrained personnel. If it is used incorrectly. If it is not used in accordance with its intended use.
Safety instructions Safe working Observe all safety instructions set out in the manual, the applicable national accident prevention regulations, and the valid company work, operation, and safety guidelines. DANGER: Due to flying parts. Tools that are not clamped correctly will be flung away by the centrifugal forces that occur during machining.
Safety instructions The tool cutting diameter (X) must not be greater than the maximum clamping range (Y). Ü Always clamp the tool so that it is as short as possible. Ü Keep the dimension (Z) small. Ä (Y) See section: Technical Specifications 14].

Technical description Electrical connection The HF spindle may only be operated with a frequency converter (FC). Ü Check whether the current, voltage, and frequency data of the HF spindle match the raw data for the frequency converter. Ü Use a motor supply line that is as short as possible. Ü...
Technical description Sealing air For guidelines on air quality, The sealing air prevents foreign bodies such as chips and liquids (e.g. emul- see "Air purity classes (ISO sions) from entering the HF spindle. 8573-1) 26]" section. Ü Check that air escapes at the front between the housing and the rotating parts of the HF spindle.

Technical Specifications Speed and position sensor (MiniCoder) The MiniCoder scans a target wheel (toothed wheel) made from ferromag- netic material. The magnetic field of the built-in encoder is modulated by the moving target wheel. The sensor detects the change in magnetic field and converts this into a si- nusoidal output signal.
Operating location Air-borne noise emissions CAUTION: Noise has an impact on health. Only operate the HF spindle if you are wearing hearing protection. Operating location DANGER: Due to flying parts. If the HF spindle is incorrectly attached, it may come loose during operation and be flung away by the forces that occur.
Installation Installation Before installation: Ü Check the HF spindle for damage and ensure that it is complete. If the HF spindle has been stored for a long period: Ü Carry out all steps in the Commissioning after storage section. Installing the HF spindle Complete the following steps in sequence to install the HF spindle: Ü...

Installation 8.4.3 Setting values For guidelines on air quality, Ü Keep to the following values: see "Air purity classes (ISO Taper cleaning 4,5 - 6 bar 8573-1) 26]" section. Pneumatic system for tool change ≥ 6,0 bar Item no. 10408018, Revision 03 27 ( 44 )
Commissioning Commissioning DANGER: Due to flying parts. If the speed is selected incorrectly, the HF spindle or the tool may be de- stroyed and their fragments may be flung out. Note the maximum speed for the selected tool. Note the maximum speed for the HF spindle. The maximum permissible speed of the HF spindle for commissioning / processing is always the lowest...
Commissioning Daily start-up Proceed as follows to preheat the grease lubrication of the bearing and to protect it: Ü Operate the HF spindle with a clamped tool (without machining). Ä Approx. 2 minutes. Ä At maximum 50 % of the maximum permissible speed. (See Commissioning 28] section)
Tool change Tool change CAUTION: Danger of being drawn in by rotating shaft. If the shaft is still rotating, fingers and hands may be drawn in and crushed. Only change the tool if the shaft is at a standstill. Note: Ensure functionality. Never operate the HF spindle without a clamped tool shank.
Tool change 10.2 Pneumatic taper change DANGER: Due to flying parts. The taper cleaning could build up air pressure in the hollow shank taper dur- ing the tool taper change. This air pressure flings out the hollow shank taper in the case of sudden release. Always switch off the taper cleaning when the hollow shank taper is ap- prox. 1-2 mm away from the contact surface.
Tool change 10.3 Tool changing station (optional accessory) During a tool change, the HF spindle moves into the changing station with the clamped tool. Ü Note the following values when producing the changing station in order to compensate for the ejection travel (X): Spring loaded X = 2 - 5 mm Spring force...

Tools for high speed cutting Tools for high speed cutting DANGER: Due to flying parts. If the wrong direction of rotation is used, the tool is damaged when load is applied. The centrifugal forces cause the broken part to be flung out. Only use tools with the correct direction of rotation for the HF spindle.
Maintenance Maintenance Only specialist personnel may perform maintenance on the spindle. The HF spindle must be shut down before any maintenance work. Ü Make sure that the shaft of the HF spindle has come to an absolute stand- still. Ü Before carrying out any work, read the corresponding section of the man- ual carefully again.
Maintenance 12.2.3 Every time the clamping device is changed Ü Clean the inner taper of the HF spindle shaft. The inner taper must be free of chips and contamination. Ü Clean the tool taper. Ü Apply a light greasy film to the taper of the collet after cleaning. Ä...
Dismantling Dismantling Proceed as follows to remove the HF spindle: Ü Completely disconnect the power supply. Ü Completely disconnect the media supply (air and liquid). Ü Make sure that the shaft of the HF spindle has come to an absolute stand- still.
