CNC-Micro-Finishing-Machine THIELENHAUS - CenterStar ZS 412 - Z-Axis - W-Axis - B-Axis swivable Description (functions) Picture 1: Oscillation Adjustment (Thread Machining) The adjustable flanges are used for adjusting the correct stone position. They have to be adjusted manually according to the pitch of the rack. The adjustment has three parameters (Diameter, Pitchangle and Pitch). The rear base bracket is fixed on the machine bridge. They carry the front base bracket which can be adjustet sideways. Using the gage block „S“ this allows for different pitches. The gage blocks D1.1, D2.2 and D2.3 are used to adjust the diameter by moving the intermediate plates.The gage blocks W1.1 and W2.2 are used to adjust the pitch by rotating the Flanges which carry the oscillation motors. The tool carries are mounted to the oscillation motors with a locking sleeve and a locating pin. The oscillation motors have absolute encoders and air purge. Using the absolute encoder the Microfinishing stone can be set to any angle and oscillate around this starting angle by a defined oscillation angle. The gage blocks can not be put into the wrong location and are held on the machine during adjustment by pins. All the flanges are held by locking screws. The gage blocks only have to be changed if new workpieces are to be machined. The gage blocks are labeled: X = D; W or S for angel, diameter or pitch. Y = 1, 2, 3... for differnet parts angle, diameter. Picture 2: Tool Carriers and Stone Holders The toolcarrier is mounted to the oscillation motor shaft and carries the tool holder with the locked Micrpfinish stone. The tool carrier consists of a housing with linear buchings and a slide. The slide is actuated by two hydraulic. The slide presses the stone holder and the stone against the machining surface of the workpiece. The hydraulic pressure in the tool carrier is controlled by the software and a proportional valve and is monitored by a pressure switch. The pressure has to be set according to the machining task, the stone hardness and the part quality. The set screws on the tool carrier have to be adjusted so that the stone holder can not touch the workpiece in the evnet of a worn or broken stone. The stones are locked inside the too hloder with a spring. The adjustment is done automatic by the „Stonemaster“ Picture 3: Stone Worn-/Stone Broken Detection The stone worn- / stone broken detection is done by pneumatic poppet valves which are integrated into the too carrier. If the tool carrier slide moves too far into the direction of the workpiece (in case of a worn or broken stone) the valve stem hits the the screw. As the stone wears the first valve release pressure which is detected by a pressure switch in the ingoing pneumatic line. In the case of a broken stone the second valve also release pressure causing a different reading on the pressure switch. The control stops the automatic cycle and displays an error message on the HMI screen and on the stack light. Picture 4 / 5: Stonemaster (Automatic Stonefeed) The automatic stone feed „Stonemaster“ consists of the tool holder, the actuator and the back stop. The stone holder is mounted to the tool carrier which is on the oscillation motor. This way the tool holder can be swiveled into any angular position. The stone holder locks the stone in place with a polyurethane washer which is acting as spring. It aslo has a release mechanism consisting of a small drawbar. Due to this set up the mass of the system is low and does not have a negative influence on the oscillation. The actuator unlocks the stone in the tool holder according to the commands given from control. It consists of a base bracket with an integrated support surface, a lever with a fork style head and a pneumatic cylinder. The actuating unit is mounted to the same flange as the oscillation motor and can be advanced to the working position by a second pneuamtic cylinder and linear guides. During machining the stonemaster is retracted., so that it doesn't interfere with editing. Picture 6: Groove Position Detection The groove in the rack is being detected by a proximity switch. The groove position detection is mounted to the steady rest bracket. The work slide Z1 positiones the rack underneath the proximity switch. This determines the right and left flank of the groove and the control calculates the center of the groove.
