Read OnA grinder for gear cutters with a grinding wheel dressing device attached thereto in which the grinding wheel spindle stock and the dressing device are coaxially pivotable and rotationally interconnected by planetary worm gear drives and spur gears so as to positively set the angular position of the dressing device as a function of the angular position of the grinding spindle.
Read OnW. Brian Rowe, in Principles of Modern Grinding Technology (Second Edition), 2014. 10.6 Plain Hydrodynamic Spindle Bearings. There are many designs of plain hydrodynamic spindle bearings used for grinding wheel spindles. An example of a simple plain bearing arrangement is shown in Figure 10.11(a). The bearing is basically a cylindrical sleeve ...

Read OnThe arrangement of the grinding spindle axis on this machine enables an extreme freedom of movement on both sides via a total rotation angle of 240°. This means that both right-hand and left-hand tools can be ground with the same wheel pack. The 6th axis also makes it possible to tilt the grinding wheels during grinding.
Read OnThe spindle turret on the B1 axis is equipped with a unique compact grinding spindle head with a flexible internal grinding spindle arrangement for a maximum of four grinding spindles. The table turret on the B2-axis can optionally be equipped with a workpiece spindle head and a high-precision rotation axis (C-axis) including a direct path ...
Read OnGrinding spindles The modular spindle support concept enables optimal adaptation to the grinding task. Up to 3 spindles in a parallel arrangement can be used on the S122. One spindle can be equipped with an external grinding wheel. The spindles can be individually equipped with the proven arbor deflection compen-sation system.
Read On5. Bearing Arrangements and Structures of Bearings for Main Spindles 22 Technical Data Typical examples of bearing arrangements for main spindles of machine tools are summarized in Table 5.1. An optimal bearing arrangement must be determined through considerations about the properties required of a main spindle in question (maximum speed ...

Read OnGrinding efficiency measured in terms of material removal rate is achieved by employing ultra high wheel speeds. The spindle is a key component for ultra-high-speed grinding machine tools and the development of a "high power–high rotational speed" spindle is a daunting task owing to the lubrication challenges.

Read Onour aim is to focus on the spindle such that the measurement only reflects its contribution, the fixturing would be bolted directly to the stator. This arrangement minimizes the influence of structural mo-tion and vibration on the measurement. If we are more interested in the motion in the entire structural loop, we might use fixturing to
