The spindle of the CNC drilling machine can go down, but the drill bit can t go down

The spindle of the CNC drilling machine can go down, but the drill bit can't go down, considering that the material of the drill bit is not hard enough to drill into the material. CNC drilling machine is mainly used for efficient processing of workpiece drilling, tapping (rigid), flange, disc and ring parts.

The company was founded in May 2008 and is located in Suzhou City, Jiangsu Province, with more than 100 employees. Suzhou Longkai Electromechanical Technology Co., Ltd. is a modern new CNC equipment company integrating R&D, manufacturing and sales. The company's main spinneret die, CNC drilling machine, CNC perforating machine, fast wire cutting, wire cutting, turret milling machine, surface grinder, EDM machine and other mechanical and electrical equipment are exported to all over the world.

The spindle of the CNC drilling machine can go down, but the drill bit can't go down

Hello dear! We'll be happy to answer for you. The spindle of the CNC drilling machine can go down, but the drill bit can't go down, what is going on?

1.If you haven't drilled in place, you haven't drilled to the bottom of the cement stabilized base 2Drill to the bottom, can't lift the drill bit, the core sample is all scattered, can not form a whole filial piety number like a body, indicating that the cement dose is small, the construction unit has cut corners.

3.After the health period, the lead can be drilled and sampled after the health period, otherwise the cement will not reach the strength and the gravel can not be cohesive. 4.

If the core drill machine runs out of oil or the engine has a problem, see if the lower damper is blocked. Drilling refers to the operation of using a drill bit to make a hole in a solid material. The control of the position accuracy of the drilling hole is essentially the control process of the correct position of the drill bit and the workpiece during the drilling process.

When the drilling hole is fast and penetrating, the manual feed force must be reduced to prevent the feed from suddenly being too large, increasing the cutting resistance, causing the drill bit to break or causing an accident to make the workpiece rotate with the drill bit.

Hello, the above questions will be answered by me. CNC drilling machine does not drill is due to the following reasons: 1

If you don't drill in place, you haven't drilled to the bottom of the cement stabilized base layer earlyDrilling to the bottom, the drill bit can't be lifted, the core samples are all scattered, and the whole cannot be formed, indicating that the cement dose is small, and the construction unit has cut corners. 3.

Before the health period, the core can be drilled and sampled only after the health period has passed, otherwise the cement hail will not reach the strength and cannot make the gravel bond. 4.If the core drill machine runs out of oil or the engine has a problem, see if the lower damper is blocked.

Hope it helps!

There are several reasons for this.

1: The host does not start the power supply (this is the most likely to happen to many manipulators, and the point that should not happen).

2.The start button is not in good contact and cannot respond immediately (if the contact is not good, the host will not be able to immediately act accordingly to the command, but this point is most easily ignored by the manipulator).

3.The contactor does not engage (if the contactor does not engage, it will cause the wiring of the main motor junction box to be in poor contact, or cause the connector to fall off).

The main engine does not respond when we start the power supply, but we turn on the main engine after powering on, but we find that the main engine cannot operate. This is usually due to two factors. The first is poor contact, so that even if the power is on, the host will not be able to respond in time; The second is that the contactor does not engage properly, which can lead to a bad wiring position.

Oil leakage in the spindle, shell and other parts of the equipment When using a fully automatic CNC drilling machine, the shell and spindle of the machine may have oil leakage. At this time, we must find out the cause of the failure in time.

The main engine does not rotate after the CNC machine tool is started, which is generally caused by the following situations: 1. It is due to the problem of the zero point switch, and the PLC does not produce a deceleration signal! 2. There is a problem with the measuring board of the CNC system, and the zero pulse is not received!

3. There is a problem with the zero pulse of the encoder or grating ruler!

The reason why the power supply does not start may not be done well or the switch of a certain link is not opened, because since it is the CNC that all conditions are met before it can be started. And see if all the relay feedback signals are returned? Especially in terms of numerical control, there is an indicator that he can't start.

Dear, you are good for two main reasons: 1Poor chip evacuation.

It may be because the amount of dry drilling or cooling water is too small, so that the debris cannot be discharged and the drill is stuck. 2.During the drilling process, the drilling object is brittle and forms large particles or there are small steel bars inside, which cannot be discharged due to the large size and causes the drill to be stuck.

Scramble 3The drill bit bit is not firmly welded, and the drill is stuck due to the falling cutter head. Fault Troubleshooting and Prevention:

1.Pay attention to the sound when drilling, and when the sound is abnormal, raise the drill bit in time to see if there is any debris or core break and take it out in time. 2.

When encountering drilling objects that are easy to break the core or have large particles of gravel or slow reeds and small steel bars, the feed pressure should be reduced and the drilling situation should be paid attention to at any time. Hope it helps.

1.To ensure that the drill bit is not easy to break, you can start to improve from the following aspects:

1) When using, take out the drill bit from the box and immediately install it into the spring chuck of the spindle or the tool magazine of the automatic replacement of the drill bit. Put it back in the box when you're done.

2) Measure the diameter of the drill bit with a non-contact measuring instrument such as a tool microscope to avoid the cutting edge being injured by contact with the mechanical measuring instrument.

3) Some CNC drilling machines use positioning rings, some CNC drilling machines do not use positioning rings, such as the use of positioning rings when the depth positioning of its installation must be accurate, such as the use of positioning rings its drill bit installed on the spindle extension length to adjust consistently, multi-spindle drilling machine should pay more attention to this, to make the drilling depth of each spindle to be consistent. If there is inconsistency, there is a risk that the drill bit will drill into the table or fail to drill through the circuit board, resulting in scrap.

4) Always check the concentricity of the spindle and the spring chuck and the clamping force of the spring chuck, the concentricity is not good, it will cause the small diameter of the drill bit to break the drill and the hole diameter is large, etc., the clamping force is not good, the actual speed is not consistent with the set speed, and the chuck and the drill bit slip.

5) Always check the spindle presser foot. The contact surface of the presser foot should be horizontal and perpendicular to the spindle and not shaken to prevent broken drilling and deviation in the drilling.

6) The dust suction effect of the drilling machine should be good, the suction wind can reduce the temperature of the drill bit, and colleagues can take away the dust to reduce friction and produce high temperature.

7) The drill bit is re-sharpened in a timely manner, which can increase the use of the drill bit and the number of re-grinding, prolong the life of the drill bit, and reduce the production cost and expense. Usually measured with a tool microscope, the wear depth should be less than within the full length of the two main cutting edges. Grind off when regrinding.

The regular cutter drill can be reground 3 times, and the undercut drill can be reground 2 times. If there is too much grinding, the drilling quality and accuracy will be reduced, which will cause the scrapping of the finished circuit board. Excessive grinding is counterproductive.

8) Pay attention to the adjustment of machine tool processing parameters.

2.Reasons for broken drill bits:

1) If the size of the drill bit is not suitable for matching the processing parameters (speed, feed);

2) The material of the workpiece does not match the material of the drill bit;

3) Incorrect drilling pattern;

4) Chip removal is not good;

5) Poor chip punching and cooling of drill bits;

Each time with less feed and more chip removal, the drill bit is not easy to be squeezed to death by the chips and break the drill bit.

The landlord you said that the CNC drill bit is not easy to break, this has a lot to do with our own grinding, the standard edge angle is 118 degrees, the cross edge angle is 55 degrees, if the hard material can be grinded double edge angle to increase the strength of the drill bit, in addition, our spindle and feed should be matched with S600, F50 60 can, the material is different can be modified by yourself, the drill bit is sharpened with a good spindle speed and feed The drill bit is not easy to break, I hope it can help the landlord!

The feed is slower, the number of revolutions is better, it is best to follow the wire, not too fast, the center of the grinding is a little, and of course the quality of the drill bit should be better!

The CNC drill you are talking about should be cemented carbide, what material are you machining?
