Problems with ordinary lathes, instrument lathes, CNC lathes spindles

Suzhou Haideler CNC machine tool **** for you to answer: before the presentation of CNC lathes, there are a variety of automatic lathes used in industrial production. CNC lathe digital control technology is used for lathe products.

Therefore, it should be said that CNC lathes are one of the automatic lathes. The difference between CNC lathes and non-CNC automatic lathes is whether digital control technology is applied to control the machining process of the lathe. Conservative automatic lathes mostly use mechanical devices to achieve continuous change of analog quantity for sequence control (such as time distribution axis, shaping tool, cam, die, etc.), which has the characteristics of reliable work, fast speed and high repeatability.

The disadvantage is that changing the processing variety needs to be replaced, adjusted, and tooled. It's a long time. Adapt to the medium batch of workpieces and mass production.

The CNC lathe compiles the work through the processing sequence, and its control instructions are set to the machine in the form of digital signals

The spindle of the lathe, the sleeve of the bearing is matched with the interference of the bedside box, which is generally achieved by the percussion method, the temperature difference method or the press-in method, and the corresponding loading method can also be applied when it is poor, but the reverse is the opposite. There is also a pull rod remover (puller), when dismantling, you must remember to put the force on the inner and outer rings of the match, I hope it will be useful to you.

It's too general, the general car and the CNC lathe spindle and bearing are separated, generally there are 3 bearings, divided into front bearings, rear bearings and a plane bearing, the advantages of it or numerical control, it is best to be wide.

4075 means: when the position deviation is within the set value, orara = 1 (spindle orientation signal), which is the width of the position.

Parameter description:

Parameter Upper speed of spindle speed, vmax=4095 Upper speed of spindle motor Command voltage 10V spindle motor speed ) is set to 4095 4500 6000=3071.

Parameter Lower limit of spindle speed, vmax=4095 lower limit of spindle motor speed Command voltage is 10V spindle motor speed) is set to 4095 150 6000=102.

The corresponding spindle speed a when the command voltage is 1ov, and the low gear ) is set to 6000 11 108=611. Slim respect.

CNC lathe is a high-efficiency machining equipment, which is capable of completing complex CNC machining tasks. However, it is possible that the spindle does not rotate during use, which will lead to a decrease in production efficiency. Below, let's take a look at the reasons and solutions for spindle not rotating.

First, the spindle is faulty. The spindle is the core part of the CNC lathe, if the spindle cannot rotate normally due to wear, rust or bearing failure, then it will lead to the failure of the entire equipment to operate normally. The solution to this problem is to repair or replace the spindle.

Second, the motor is damaged. The spindle drive of the CNC lathe is based on the lead chain by the motor, if there is a problem with the motor, then it will naturally cause the spindle to fail to rotate normally. In this case, it is necessary to balance the need to replace the motor or repair it.

Third, the issue of power supply. The operation of CNC lathes requires a stable power supply**, and if there is a problem with the power supply line, it will cause the spindle to not rotate. In order to solve this problem, you need to check whether the power supply line is normal, or replace the power line.

In short, the spindle does not rotate is one of the common faults of CNC Huai Liang Sun lathe, but this problem will not have much impact on production, as long as the cause of the failure is found out in time and repaired, the equipment can be re-operated normally and ensure production efficiency.
