The machining center is automatically running and the spindle is not positioned 15

Could it be that when you just reach the fifth, you should feel that the device signal is not in place, check if there is a sensor blocked by the fifth knife, and you can't get the signal.

If it is the above problem, it should be that the spindle bearing of the machine tool is broken, the spindle clearance is too large, you can try what is the difference between the positioning position of the spindle with high-speed gear and low-speed gear, generally the low-speed gear can be changed, and the early tool change program can add S100 a line before the spindle positioning M19. Will be ok.

Reasons and solutions: whether the spindle has a positioning action, if the positioning is not in place, the tool change will be stuck; If it is the above problem, it is the machine tool spindle bearing is broken, the spindle clearance is too large, try to position the spindle with high-speed gear and low-speed gear, generally the low-speed gear can be changed, and the early tool change program can add S100 a line before the spindle positioning M19.

A spindle is a shaft that receives power from an engine or electric motor and transmits it to other components. The spindle, also known as the "optical axis", is the abbreviation of the "main optical axis": the diameter that has symmetry in the optical apparatus group.

For example, the spindle of a spherical mirror is a straight line perpendicular to the mirror through the center of the mirror. The main axis of the lens or optical axis optical group is the line connecting the center of each lens.

Check out the tool changer macro. See if there is a problem with the tool change procedure.

Hello! I've seen your question here, I'll get back to you later.

Kiss. The manipulator did not return to square one. or the system does not collect the manipulator origin signal.

2. The solenoid valve of the knife sleeve flipping cylinder is faulty, and the knife sleeve return action is not executed. 3. The gas circuit failure of the knife sleeve flipping cylinder, such as: insufficient air pressure, air path is not passable, etc.

4. Mechanical failure of the knife sleeve flipping mechanism, such as: the knife sleeve flipping lever is broken, other parts of the turning mechanism are damaged, and the knife sleeve is stuck.

Questions. Rotating the cutterhead alone does not rotate.

Dear, first rule out whether there is a circuit problem, mechanical problems are generally disassembled to see if there are any parts rotten (my central shaft is often broken), wash it with kerosene and reinstall it. Hope it helps! We look forward to getting your likes! Thank you!

Questions. There is an anomaly warning light that comes on.

<> except for the tool change, there is no reaction to the tool change or the tool number is changed separately, and the rotary cutterhead has no response.

Pro, 1 Sensor: Sensors include water temperature, crankshaft position, air flow, inlet air temperature, oxygen sensor; 2.Air Intake Problems:

When the engine burns, it needs to take intake, and the air filter is very important in this process, if the air filter element of the car is not clean, it will affect the air intake of the car if it is not cleaned regularly; 3.Poor combustion of the mixture: faulty spark plug of the engine, faulty ignition coil, faulty fuel pump, hope to help you.

Thank you! Pro: You press the valve again (press on both sides) to see if the lower tool magazine has the action of extending and retreating, remember to lift the spindle up, so as not to damage the spindle. Hope it helps! Thank you!

What is the situation when the spindle shank of the machining center is loose and the tool cannot be tightened.

The spindle shank of the machining center is loose, and the tool is not tightened, what is the situation, the Latin of the <> tool holder is loose (preload it) The disc spring in the spindle tie rod is broken (disassemble the spindle tie rod and change the disc spring) (1) Gantry boring and milling machining center analyzes the reasons why the spindle does not tighten the tool The disc spring of the spindle tension tool is deformed or damaged; The action of the tensile hydraulic cylinder is not in place; The threaded connection between the tie rod and the chuck of the shank is loose. (2) Check and confirm the cause and location of the fault After inspection, the disc spring and hydraulic cylinder are normal, and it is found that the threaded connection between the pull rod of the machine tool and the chuck of the tool holder is loose, and the chuck of the tool holder rotates with the insertion and withdrawal of the tool, and retreats about mm. There is no locking measure of connection and anti-loosening between the tie rod and the tool holder spring chuck of this machine tool, and when inserting and removing the tool, if the tool center and the center of the spindle positioning taper hole are slightly deviated, there will be an eccentric friction between the tool holder spring chuck and the tool holder.

Summary. All machining centers suffer from this problem. Generally, when the machine fails during the tool change process and the collision of the machine tool is found, it is necessary to press the emergency stop.

All machining centers suffer from this problem. Generally, when the machine fails during the tool change process and the collision of the machine tool is found, it is necessary to press the emergency stop.

Signal sensing is one thing, and the brakes are not working on the other, and that's right, I clicked the reset button when the machine changed tools.

It gets stuck there, showing that the arm is at the anchor point.

It can be judged from the following aspects: 1. When the knife arm is about to return to the original point, there will be a period of time when it will not move, and there will be about 10 seconds. 2. You can observe the induction switch, if it is in place, the positioning sensor will be lit, and it is generally the sensor in the middle.

I don't understand it very well, it's just simple, I hope it works.

Summary. Hello, generally speaking, there may be two kinds of problems in this situation, 1. The manipulator because of the collision of the tool, so that the actual positioning coordinates of the manipulator deviate from the control coordinates in the CNC system, so that when the tool is returned, the control coordinates in the CNC system are displayed in place, but the actual manipulator does not return to the original position (far point), if this is the case, the operation interface of the CNC system re-zeros the tool, and sets the compensation coordinate value, so that the tool can return to the original far point.

2. The mechanical structure inside the manipulator is damaged, the reducer is damaged, the sensor is misaligned, etc., in this case, the manipulator should be disassembled to be carefully debugged, and if necessary, part of the parts should be replaced, or the position of the sensor should be adjusted to reset it. After changing, you can reset the tool to zero.

What happens if the machining center robotic arm can't go back to the far point after the automatic tool change?

After the automatic tool change of Fanuc machining center, the tool change arm stops on the spindle tool, does not return to the original position, and there is no alarm.

In this case, the manipulator strikes the knife and causes damage to the internal mechanical structure of the manipulator, damage to the reducer, and misalignment of the sensor.

It needs to be repaired.

Summary. The machining center tool magazine will first lower all the knives.

Then enter the tool magazine management interface, reset the tool magazine serial number, and then put the tool holder back into the seat. The spindle does not move up when changing the tool: the general spindle is not at the tool change point is not possible to change the tool, if you want to manually return to the tool change reference point, you can use G91G30Z0, and then change the tool.

You can refer to the machine manual.

When the FANUC machining center changes the tool, I press the reset, and the tool magazine and spindle are stuck, how to solve it? The robotic arm also does not rotate manually.

The machining center tool magazine is messy, first Hongyu will go down all the tools and then enter the tool magazine management interface, reset the tool magazine serial number, and then put the tool holder number back into the seat. The spindle does not move up when changing the tool: the general spindle is not covered by the gear section and it is impossible to change the tool at the tool change point, if you want to manually return to the tool change reference point, you can use G91G30Z0, and then change the tool with the stupid bridge.

You can refer to the machine manual.

The knife is jammed on the spindle to exchange, and then adsorb.

The screw arm that is stuck in this position and manually screwed on it does not move.

The manual spindle loosens the gauge solenoid valve, and then the manual tool magazine returns to the solenoid valve, and the two people should cooperate, pay attention to the safety of the hall, and the tool may fall off. After the knife magazine is returned, if the tool magazine has a function of returning to zero, it is OK to return to zero.

You have all these questions, whether the whole point is professional or not.

**See, no, this kind of holding, how to deal with it, give a maintenance method, from**to**.

Roll the calf and waste my brother's dollar.

Wait a minute, I'm looking up for a related message.

Switch to MDI mode, enter MO6T** and press the cycle to start the packet. MDI is a manual input program control mode, the working mode of the machine tool is divided into manual, MD and automatic mode, working in MDI mode by manually entering MO6T**** and then pressing the cycle start key, and the first execution can be. If the requirements in the division are not high, or the workpiece is a blank, and the shape is excavated and can be milled, in order to facilitate the operation, the cutter used in processing can be used to directly touch the cutter, so as to determine the origin of the work, and its steps are as follows:

1. Install the milling cutter to be used on the spindle, and make the spindle rotate at the speed of the hand; 2. Manually move the milling cutter to approach the measured edge of the workpiece along the X direction until the milling cutter is just cutting the workpiece material of the cutter; 3. Keep x and y unchanged and raise the z axis in the +z direction, and set the x axis to zero at the relative value. If you really can't repair it, it is recommended to find a professional to help, otherwise it will outweigh the losses if it is broken

Summary. Hello, pro, after the machining center tool change is completed, the tool arm does not move, the reason may be that the tool magazine is changed, the tool arm has been changed and ready to return, the tool magazine is ready to release and rotate the next knife, the air pressure is insufficient, the machine tool alarm, the manual rotation tool arm returns to zero in place, but the tool magazine is in a loose state, so the alarm can not run, that is, the tool magazine does not turn, there is a gate knife behind the machine tool electrical library is separated, and it can be closed.

Hello, pro, after the machining center tool change is completed, the tool arm does not move, the reason may be that the tool magazine is changed, the tool arm has been changed and ready to return to the position, Chachai no tool magazine quasi-Zhaozhi is ready to release and rotate the next knife, the air pressure is insufficient, the machine tool alarm, the manual rotation of the rotary tool arm back to zero in place, but the tool magazine is in a loose state, so the alarm can not run, that is, the tool magazine does not turn, there is a gate knife behind the machine tool electrical library is separated, and it can be closed.

1. Tool magazine failure 1, if the tool magazine can not rotate, the reasons may include: the coupling of the motor shaft and the worm shaft is loose; The inverter is faulty, and the electric attitude is not electrified; Faulty proximity switch or reed switch; The PLC has no output control, or the PLC has an output but the relay in the interface board fails; Low air pressure. The solution to Brother Fang's book trouble is:

Check and adjust the coupling; Check whether the input and output voltages of the inverter are normal; Check the IO status through the IO monitoring screen of the PLC, adjust or replace the proximity switch or reed switch, check or replace the relay; Adjust the air pressure to the specified value. 2. If there is a problem of inaccurate positioning of the cutterhead, the envy cover may be caused by the wear of the motor brake. It can be solved by adjusting the adjusting screws in the motor brakes.

The tool falling when the tool is reversed may be caused by insufficient spring clamping force in the tool sleeve or cannot be reset normally, and the distance between the tool holder and the rivet is incorrect. Components must be adjusted or replaced. 3. If the knife sleeve is broken, the reason may be:

Before the tool sleeve is not positioned, there is a reverse action or the cutter head is rotated before the knife is not returned, and it is damaged when the tool is loaded. The solution is to adjust the position of the cutterhead positioning proximity switch or the reed switch of the inverted cutter cylinder and replace the cutter sleeve. Electric motor burnout has occurred, and the possible causes include:

The power supply is out of phase or the voltage is incorrect, the brakes are burned out, the tool is overweight, and the component is not operational. The solutions are: check whether the contactor contact is damaged, whether the power supply is out of phase and whether the voltage level is matched; Detect whether the brake coil is damaged and whether the grounding is correct; Check whether the quality of the tool exceeds the allowable value; Check whether the sliding part of the knife sleeve is smooth.

Second, the manipulator failure 1, such as the spike fruit is the tool clamp is not tight enough, often drop the knife, may be due to the pressure of the claw spring is too small, the nut behind the spring is loose, the manipulator lock does not work, the tool is overweight and other reasons. The solution is to tighten the spring back nut, adjust or replace the clamp lock, replace the spring, and change the tool. 2. If it is found that the tool cannot be loosened after clamping, the reason may be that the jaw spring pressure is too tight, and the jaw cannot be retracted.

The solution is to loosen the nut or replace the spring so that the maximum load does not exceed the rated value.

Summary. The shortcomings of each tool position of the vertical machining center tool magazine are constantly rotating, mainly due to the following aspects. 1. The system has a reverse control signal TL-output, but there are doubts about the loop between the system and the tool magazine motor; Check whether there is an open circuit in the connection of each center, check whether the contact is poor, check whether the DC relay and AC contactor in the strong current cabinet are damaged2, the +24V voltage on the tool position of the vertical machining center system is low, and the pull-up resistance on the line is open; Use a multimeter to measure whether the voltage on each tool position is normal, assuming it is low, check the pull-up resistor, if it is open, replace the 1 4w2k pull-up resistor.

The tool change arm of the machining center keeps turning Why.
