  • Page 30: Testing The Spindle Nose

    Assembly Testing the spindle nose The machine side must be aligned prior to the installation in order to achieve high run-out accuracy of the lathe chuck. To do this, check the contact surfaces on the spindle for axial and radial run- out accuracy using a dial indicator.

  • Page 31: Assembly Of The Lathe Chuck (With Cylindrical Recess)

    Assembly 5.3.1 Assembly of the lathe chuck (with cylindrical recess) NOTE If the interface of the machine spindle and lathe chuck is identical, the assembly is carried out without assembly preparation. If the mount of the machine spindle deviates from the mount of the lathe chuck, a connecting flange must be affixed before the chuck is assembled.

  • Page 32: Assembly Preparation For Lathe Chuck With Reduction Or Expansion Adapter Plate

    Assembly 8 Check the lathe chuck again for concentricity and axial run-out accuracy (see Fig. "Lathe chuck assembly" - E ( 5.3, Page 30)). The "Concentricity and axial run-out tolerances" table shows the concentricities and axial run-out accuracies to be achieved. 9 Check the jaw stroke of the base jaws and that these can move easily.

  • Page 33: Assembly Preparation For Lathe Chuck With Direct Mounting

  • Page 34: Function

    Function Function Function and handling The manual lathe chuck ROTA-M flex 2+2 has a centrically balanced clamping function which enables the clamping of round, cubic and geometrically bulky workpieces. The opposite jaws move centrically towards each other. The workpiece is centered in two compensating planes that are perpendicular to each other.

  • Page 35: Replacement Or Renewal Of Jaws

    Replacement or renewal of jaws Changing the top jaws When changing the top jaws, the serration has to be cleaned and greased with SCHUNK LINOMAX plus special grease. Tighten the jaw mounting screws (screw grade 12.9) to the ( 4, Page 28) specified torque.

  • Page 36: Clamping The Workpiece

    Function Clamping the workpiece 1 Determination of the required actuation moment is based on ( 3.4, Page 23) the clamping force calculation. 2 The workpiece is clamped by twisting the spindle (item 8) using the actuation key or a torque wrench. 3 Check both stroke controls, which are located below the guideways 1 and 4.

    Function Compensation / workpiece dimensions ROTA-M flex 2+2 Overall stroke per jaw [mm] 11.4 14.5 17.8 17.8 Compensation per jaw [mm] The compensation area of the lathe chuck is located in the center of the total jaw stroke and is also the area within which the indicator pins are completely recessed.

  • Page 38: Maintenance

    Maintenance Maintenance Lubrication To maintain the safe function and high quality of the lathe chuck, it has to be regularly lubricated at the lubrication nipples in the chuck body. The lathe chuck must be lubricated in the open position. For optimum grease distribution, the chuck piston must travel through the entire stroke several times after lubrication.
