    Delivery, interdepartmental transport, assembly and commissioning Notes on transport, installation, commissioning Improper transport, installation and commissioning is liable to accidents and can cause damage or malfunctions to the machine for which we do not assume any liability or guarantee. Transport the scope of delivery secured against shifting or tilting with a sufficiently dimen- sioned industrial truck or a crane to the installation site.

  • Page 21: Unpacking The Machine

    Unpacking the machine INFORMATION The surface grinding machine is pre-assembled. The delivery takes place in several transport boxes. After unpacking and transport to the installation site, individual components of the sur- face grinding machine must be assembled and joined together. Install the machine close to its final position before unpacking.

  • Page 22: Set-Up And Assembly

    For lifting with a crane, first mount the transport bolts on the base of the machine. Then attach the steel cables to the bolts and hook. Pay particular attention when transporting with a crane:  Raise the machine at the lowest possible speed. ...
  • Page 23 Design the working area around the surface grinding machine according to the local safety reg- ulations. The work area for operation, maintenance and repair must not be restrictive.

  • Page 25: Free Mounting

    ATTENTION! Insufficient stiffness of the foundation leads to superimposition of vibrations between the surface grinding machine and the foundation (resonant frequency of the components). Critical oscillations during oscillating movements of the grinding table are reached very quickly if the overall system is not sufficiently rigid and lead to poor grinding results.

  • Page 26: Cleaning The Machine

    The surface grinding machine was painted with a one-component lacquer. Take this criterion into account when selecting your cooling lubricant. Optimum Maschinen Germany GmbH does not accept any guarantee for consequential dam- age caused by unsuitable process abrasives. The flashpoint of the emulsion must be higher than 140°C.

  • Page 27: Electrical Connection

    Fill the container of the coolant circuit with your process abrasive. The total filling quantity in the circuit must not exceed the height of the sedimentation tank for the grinding sludge.  Connect the coolant return hose to the surface grinding machine and feed it into the cool- ant tank.

  • Page 29: Safety

    Safety The surface grinding machine must only be operated under the following conditions:  The surface grinding machine is in proper working order.  The surface grinding machine is used as intended.  The operating instructions are observed.  All safety devices are installed and activated. Eliminate or have all malfunctions rectified promptly.

  • Page 30: Grinding Table Oscillation

    Grinding table oscillation The grinding table is moved manually with the help of the hand wheel. The handwheel trans- mits the rotary movement and direction of rotation performed by hand to a toothed belt (1). The table thus moves to the left and right depending on the direction of rotation performed. The grinding table is located on a linear ball bearing (2).

  • Page 31: Magnetic Attachment

    Magnetic attachment CAUTION! Risk of material damage and personal injury! If the workpiece is less than 12 mm thick, the workpiece can detach itself from the mag- net and injure people. The material thickness of the workpiece must be at least 12 mm. The workpiece is fixed on a permanent magnet with a lever to relieve the magnetic attraction force.

  • Page 32: Mounting The Grinding Wheel

    Mounting the grinding wheel The grinding wheel included in shipment is a corundum grinding wheel with a grain size of 46. The maximum permissible peripheral speed of this grinding wheel is 35m/s in balanced condi- tion. The mounting flange (1) of the grinding wheel has balancing weights (2) which can be moved around the circumference to correct the unbalance.

  • Page 33: Balancing The Grinding Wheel

    4.9.2 Balancing the grinding wheel First the balancing device is aligned. The balancing device is placed on a firm, clean surface. A machine spirit level is placed on the running surfaces. The device is aligned with screws 1 and 2. The spirit level is now positioned diagonally on the running surfaces of the device and the device is aligned in this plane by means of screw 3.

  • Page 34: Mounting The Grinding Wheel With Flange On The Spindle

    If the disc continues to move, the two weights "K" must be moved symmetrically to the "S-G" axis in the corresponding direction. Repeat this step until the disc stops moving. 4.10 Mounting the grinding wheel with flange on the spindle ...
  • Page 35 Since the grinding wheel material is harder than the workpiece, tool steel and hard alloy steel can also be processed. Used grinding wheel material dissolves and new material appears on the surface of the grinding wheel. For good surface quality: Fine grain and hard material. INFORMATION The maximum peripheral speed of the grinding wheel must be higher than the peripheral speed generated by the grinding wheel spindle.
