7/17/13GENERAL-CNC-INFORMATION Home Company Profile Resources Contact Us General CNC Information When a machine tool continually over travels when attempting zero return, make sure the overt ravel switch is not being made before the zero return function is finished. On most machines, when reference returning, the decel dog makes the switch, the machine decels and continues at this low feed rate until the switch drops off of the back of the decel dog. At this exact instant the control commands a one revolution of the motor. after the one rev it looks for the marker. One revolution on most machines equals about .200" of axis movement. So, if the over travel switch is closer to the back side of the decel dog than .200" it may be engaged while the control is trying to find the marker. Unless you are very confident of the travel limits of the machine you should move the decel dog a little in the negative direction rather than moving the over travel dog. But either one will have the desired effect. When working with 50 Hz inductive devices the voltage tolerance is 20% of the rated value. When 60 Hz it is 10%. Normally, double arm tool changers don't use a G30. The Z axis stays put while the arm moves up and down. Therefore the machines home position is the tool change position. Also on double arm tool changers, when the arm is in the up position the spring loaded grippers can be pushed in easily. When the arm is in the down position the locking pins go up which locks the fingers in on the tool holder. This prevents the tool from being thrown. On most cylindrical grinders the table traversing left to right is done by mechanical means. The lever in the center of the travel is connected by a shaft to a directional valve so that when the lever is moved either by hand or by contact with the travel dog it switches the valve which changes direction. Normally, there will be limit switches which are actuated by a cam on the lever. These switches have nothing to do with the table traversing. What they do is cause the wheel to move in by the selected amount each time the table reaches the end of travel in each direction. On a Leadwell MCV-1300S, the standby tool is stored in Diagnostic 382. This number can be seen to change as the tool positions are counted. They will change only during an Automatic Tool Change not when magazine is jogged. Diagnostic 387 records when tool position 1 is up. It should always be a 1. Diagnostic 380 is the ATC capacity. If the tool number becomes confused: 1. Manually move the magazine to tool position 1. 2. Set Diagnostic 382 to 1. 3. Set Diagnostic 387 to 1. 4. Make sure Diagnostic 380 reflects the correct capacity. www.machinetoolinfo.com/GENERAL-CNC-INFORMATION.html 1/70 7/17/13 GENERAL-CNC-INFORMATION 5. Do a tool change in MDI to check operation. When setting the tool capacity, you must insert a whole number in BCD. In the case of the MCV-1300S, the tool capacity is 30 tools. So Diagnostic 380 must be 00110000. In true BCD, it would look like 0011 0000. Remember BCD works this way: 8421 8421 0011 0000 =3 =0 There is an instruction in the Ladder rung for M06 which checks Diagnostic 380. This instruction (LEC1) (R551.2) checks the tool number called against D380 (Tool Capacity). If the tool called is higher than D380(i.e, M06 T31), M06 will not execute. There will be no alarm, the M Code simply will not execute. If the contents of D380 is higher than the actual capacity, the result will be tool confusion. Setting D380 to a very high number will cause the magazine to continually rotate when a tool is called. Another symptom of a D380 incorrect setting is that if a number lower than the tool capacity but higher than the current tool is input, any tool number lower than the current tool or the magazine capacity can be called but nothing higher.

Mori-Seiki machines. Unlike most machines.. This switched is open and closed anytime the dial is moved to another speed setting. The spindle will begin to oscillate back and forth. 3.com/GENERAL-CNC-INFORMATION. As the drive gears are shifted these half gears move. This unit sits just below the top cover and is easily accessible. If the Servo Shift is operated improperly such as turning Dial A when Dial B is in the BRAKE position it can result in a condition in which the gears shift as soon as Dial A is moved off of the current speed before it reaches the next RPM setting. Dial A speeds: N 45 69 75 133 179 256 351 494 937 1282 1800 Dial B _________ | | Reverse |_________| | | Off |_________| | | Brake |_________| | | Off |_________| | | Forward |_________| Below Dial A is a plate held on by six screws. etc. their detents ride on levers. When the machine is run and then Dial B is turned back to the BRAKE position. the other ends of which work against a spring.After several oscillations.Place dial B in one of the OFF positions. rotate dial B to either the FORWARD or REVERSE run position. Turning the dial turns the shaft which opens and closes the various ports in the Servo Shift unit but the shift does not actually occur until dial B is placed in the BRAKE position. The higher RPM selected the wider the oscillation. In some cases this may not occur immediately but instead it may happen as a result of the vibration of putting a part in the chuck. www. Behind this plate are two plastic half gears with detents. the spindle may start to oscillate in an effort to shift to the next speed.Rotate dial B to the BRAKE position.html 49/70 .Rotate dial A to the desired RPM. The correct operation is: 1. 4. Dial A should only be turned while dial B is in one of the two OFF positions. 2.7/17/13 GENERAL-CNC-INFORMATION headstock. If dial A is turned while dial B is in the BRAKE position the Servo Shift will try to shift to the next speed range as the dial is rotated.machinetoolinfo. For 64 tools it should be 0.machinetoolinfo. etc. To check the parameters on an S-23A with a sequencer: 1. check that the limit switch for shuttle vise forward is made. of course. the signals PA and PB need a signal strength of 3 Vpp. this unit consists of an inductive sensor that is sensing a plastic gear. The gap between the sensor face and the gear is critical and should be about . according to Hyd-Mech you should always stop at NEUTRAL for a second. Typically.Turn the sequencer on while holding the INDEX button.75 2 . There is a PCB between the sensor and connector CN5. 2.7/17/13 GENERAL-CNC-INFORMATION On a machining center if there is a popping sound when the tool is removed from the spindle it could be that the collet is not releasing all the way but another cause is if the tool clean (air blast) is leaking through which will cause air pressure to build up behind the tool so that when it is released the air shoots it out causing the noise. The plastic gear has one tooth that is longer than the others and represents the reference marker. 3CR should be energwww. cause the Auto cycle to stop because the saw needs to make at least one index to execute the cut. On a Kiwa horizontal if you get alarms 2050 and 1030. This PCB has several potentiometers which are used to adjust the signal strength for PA and PB. 3. After pressing the INDEX button for the fourth time. for 120 tools it should be 1. The typical settings for parameters 1-5 are: 1 .006". it uses a PLG unit.
