Page 10: Notes On Safe Operation
Basic safety notes CAUTION Risk of damage due to incorrect choice of clamping position for chuck jaws on workpiece. If an incorrect clamping position is chosen for the chuck jaws on workpiece, the base and top jaws may break. • Make sure that the workpiece is clamped concentrically. •... - Page 11 (clamping force, coefficient of friction, wear characteristics).

Page 24: Calculation Example: Required Initial Clamping Force Fsp0 For A Given Rpm N
Technical data NOTICE For safety reasons, in accordance with DIN EN 1550, the centrifugal force may be a maximum of 67% of the initial clamping force. The formula for the calculation of the total centrifugal force F For this, n is the given speed of rotation in . -
Page 25: Calculation Of The Permissible Speed Of Rotation Nperm In Case Of A Given Initial Clamping Force Fsp0
Technical data Note: Masses of the jaw mounting screws and T-nuts are not taken into account. First the required effective clamping force F is calculated using the machining force stated: Initial clamping force during shutdown: Calculation of total centrifugal force: For two-part chuck jaws, the following applies: Centrifugal torque of base jaw and top jaw specified in "Chuck data"... -

Page 27: Attachment Of The Manual Lathe Chuck
Attachment of the manual lathe chuck Attachment of the manual lathe chuck The item numbers specified for the corresponding individual components relate to the drawing in chapter "Drawings" ( 12, Page 41). Handling prior to attachment Before mounting on the lathe, remove the base jaws from the chuck, then re-install the base jaws and turn the spindle several times as far as it will go to the right and left. -
Page 28: Assembly Of The Manual Lathe Chuck
Attachment of the manual lathe chuck NOTICE When mounting with the intermediate flange, never allow the outer rim of the chuck body to make contact. The flange must support on the entire surface. ROTA-S plus 2.0 chucks are delivered with different short taper mountings. -
Page 29: Function
Function Function The item numbers specified for the corresponding individual components relate to the drawing in chapter "Drawings" ( 12, Page 41). Handling and jaw change NOTE: For rotating lathe chucks, the centrifugal forces applied can cause the indicator pin to emerge from the chuck body. When the lathe chuck comes to a stop, the indicator pin must be reinserted. - Page 30 Function Oil the cleaned pressure bolt; do not grease with chuck grease! • Adjust exchanged jaws until the desired clamping diameter has been reached. The slides (item 12) must snap in when doing this. NOTICE Actuating the chuck if a jaw is not engaged will damage the chuck! Manually move the jaw back and forth without actuating the pressure bolt.
-
Page 31: Important Notes
Function Jaw change If you turn the spindle to the right, the indicator pin (item 17) will protrude from the chuck body (item 1) (gold-colored pin). WARNING If the indicator pin protrudes, the entire serration of the wedge bars (items 5 and 6) no longer engages into the base jaws. The base jaws are not sufficiently engaged by the wedge bars. -
Page 32: Checking The Chuck
Function • Regularly adjust the lathe chuck during operation to compensate for loss of clamping force caused by vibrations. • Following a longer period of shutdown (more than 8 hours), always re-tension the clamped chuck in order to compensate for the spindle settling and the resulting loss of clamping force. •... -
