3. GENERAL INFORMATION 3.1. PROPER USE OF ELECTROSPINDLE Electrospindles designed by TEKNOMOTOR S.R.L. shall operate as part of a machine. MACHINE DESIGN SHALL CONSIDER THAT FRAME OF THE MACHINE SHALL WITHSTAND THE WEIGHT OF ELECTROSPINDLE FITTED IN AND THE STRESSES CAUSED BY TYPE OF MACHINING TO CARRY OUT. -
Page 17: Range Of Application
The quick replacement of the shaft unit complete with bearings is possible on every models, using the shaft kit. For further information contact the Teknomotor Technical Office. All the electrospindles have a mechanical reaction system that almost completely cancels the axial force of the pistons on the bearing during the tool changing phase. -

8.2. FORECAST AND NON FORECAST USE Teknomotor electrospindles have been designed to be mounted on a machine tool for the chips removal; it is the customer’s responsibility to have any necessary interventions carried out on said machinery in order to render it compliant with Directive 98/37 EC. -
Page 30: Warming Up
At maximum rated speed of the electrospindle, the level of dynamic balancing must be G 2.5 or better (ISO 1940 standard); The balancing must be carried out with the tool-holder assembled (cone, mill, collet, ring nut, tool); The pull stud must be the one supplied by Teknomotor. 8.7. INSTALLATION OF THE PULL STUD ON THE ISO20 CONE Carefully clean the pull stud and the its housing in the ISO20 cone. -
Page 31: General Raccomandation For The Tool Holder Cones
Leave the cone to rest until the thread- blocking liquid becomes solid (see the manufacturer’s instructions). The use of non-original Teknomotor pull stud, or its non-correct installation, may cause the tool-holder accidental release. It is forbidden to use ISO tool-holders not conforming to the condition described above;... - Page 32 ATC41-ISO20 INSTRUCTION MANUAL FOR TOOL-HOLDER WITH CONICAL SEAT FOR ER DIN 6499 If the tool protrusion is longer than 80mm use absolutely extra precision collets.

ATC41-ISO20 INSTRUCTION MANUAL 9.1. SCHEDULED MAINTENANCE AND CLEANING THE SPINDLE SHAFT TOOL HOUSING Always keep the tool housing in the spindle shaft perfectly clean and free from dust, grease, coolant, oil, metal shavings, and corrosion or lime scale. Dirty housings cause incorrect tool seating, misalignment with respect to the spindle’s axis of rotation, and tool slippage. -
Page 41: Protecting The Conical Seat In The Spindle Shaft
Clean the grill of the cooling fan and remove any objects blocking the airways and control the fixing screws. The bearings are lubricated for life and do not require greasing. Component parts must be removed and refitted only by qualified personnel authorized by Teknomotor S.r.l. Only replacement of parts with original Teknomotor spares and the subsequent adjustment of the newly fitted parts is authorized. -
