1.The West-Rail-City-Centering Machine reduces the floor space and reduces the production cost. 2.
The rigidity of the parts cut out of the CNC centering machine lathe is very good. 3.The West-Rail-City-Centering Machine can continuously turn parts without stopping the spindle at one time, and it is necessary to stop and feed until the material is finished.
4.CNC centering machine is integrated with turning and milling, mainly the knife of CNC centering machine is X, Y movement, can achieve three-dimensional processing, one-time molding. 5.
Reduce the number of clamping times and improve machining accuracy. The reduction in the number of card loads avoids the accumulation of errors due to the conversion of positioning datums. 6.
Shorten the product manufacturing process chain and improve production efficiency. Turn-milling compound machining can realize all or most of the processing processes in one card installation, thereby greatly shortening the product manufacturing process chain.

Hello, mechanical watches are powered by a mainspring and rely on the balance wheel speed control system to control the operation of the watch, and its timing accuracy is affected by many internal and external factors. We know that the higher the frequency of the oscillator, the more stable the oscillation, the stronger the anti-interference ability, the more accurate the watch, the oscillation frequency of the Citizen mechanical watch is 6hz s or 8hz s (common mechanical watches are limited to its principle, ** frequency is generally between 5 10hz s), in addition, the spring full or half string, the swing or vibration caused by external force to the watch, etc., will also affect the timing accuracy of the mechanical watch. The national technical standards for the accuracy of mechanical watches are:
Allowable error within 24 hours, excellent 10-25 seconds; 1st class 20 50 seconds; Qualified product 40-75 seconds. The accuracy standard of mechanical watches stipulated by Citizen Company is: the error of 24 hours is within 20 to 40 seconds, which is judged to be qualified, which is equivalent to the excellent and first-class products of the national standard.
According to the watch phenomenon you described, the preliminary judgment has exceeded the error range, and it is recommended that you send the watch to the nearest repair network for testing and repair.

The error is larger than that of a quartz watch, due to the quality of the production and the susceptibility of the movement inside the watch to the influence of gravity. Usually the error of a mechanical watch is calculated by how many seconds per day, while the error of a quartz watch is calculated by how many seconds per month.
Count you unlucky, the quality of the purchase is not very good, go and change it??

Reasons and solutions for the second hand of the watch not to go:
1. The watch is magnetized. Due to too much contact with items with magnetic fields, the watch is magnetized and the watch needles are inaccurate, and it needs to be taken to the watch repair place for demagnetization.
2. Lack of maintenance. If the watch is not maintained for a long time, it may cause some parts to deteriorate and rust, resulting in problems such as inaccurate time and need to be maintained in time.
3. Mechanical failure. There may be a malfunction inside the watch due to other external factors. The large seconds hand of the watch is a chronograph seconds hand, which only runs when the chronograph function is activated, and automatically points to the 12 o'clock position when the chronograph is completed.
Newly bought Citizen watches.
Most self-winding watches can be wound manually, especially when wearing it for the first time or when wearing it again after stopping, rather than relying on an oscillating weight to wind the full wind.
A hand-wound watch means that the mainspring is full when it feels that it is not winded, but the self-winding watch is basically not felt, so it is recommended that the number of windings of the automatic watch should be more than less, and about 40 times will basically ensure that it can be full. But don't wind it manually often, as that will be harmful to the waterproof gasket of the handle and will affect the waterproof function of the watch.

Abnormal. Mechanical watch is powered by the mainspring, relying on the balance wheel speed regulation system to control the operation of the watch, its timing accuracy is affected by many internal and external factors, for example, it is easily affected by temperature and humidity changes, the spring full or half string, external forces caused by swing, vibration, magnetism, etc., is caused by mechanical characteristics.
In order to ensure the accuracy of the watch, the maintenance cycle of Citizen mechanical watches is generally about 2 years, and regular watch maintenance can ensure the sealing effect and waterproof performance of the watch.
There are two ways to adjust:
One: It is the daily correction of standard time.
2. Open the back cover and adjust the frequency of the balance.

Summary. Hello, I am glad to be able to ask you about the following five reasons why the Citizen mechanical watch is not gone.
Hello, I am glad to be able to ask you about the following five reasons why the Citizen mechanical watch is not gone.
Fellow, I really didn't understand, I can be more specific.
1. Citizen watches should generally be worn on the hand for more than 8 hours a day to replenish the energy of the clockwork, but it is not absolute. However, only when worn on the hand and constantly replenishing the energy of the clockwork, the Citizen watch will not stop. 2. If you accidentally bump or fall into a Citizen watch in daily use, it may cause the movement gears and other parts in the watch to loosen or misalign, which will also cause the Citizen watch to stop.
3. If the amount of activity is too large, it will cause the failure of the upper bar mechanism due to the tightening of the mainspring for a long time, and it will also cause the Citizen watch to stop due to insufficient power. Fourth, when encountering magnetic objects, it is easy to cause the Citizen watch to be inaccurate, and in serious cases, it will cause the internal movement of the watch to be magnetized, resulting in the situation that the Citizen watch stops. 5. In addition, if the Citizen watch is not maintained for a long time, the oil in the movement in the watch will dry up or condense into oil stains, which will easily lead to the wear and tear of the movement, resulting in the phenomenon that the Citizen watch is not allowed to run or even stop.

Hello, I am happy to serve you and give you the following answer: Citizen mechanical watch is not gone, it may be due to the failure or damage of the precision parts of the mechanical watch, resulting in the mechanical watch can not operate normally. First of all, the battery of the mechanical watch should be checked to see if it is depleted, and if it is depleted, it can be replaced with a new one so that the mechanical watch can function properly.
Secondly, the mechanical parts of the mechanical watch should be checked for damage, and if there are damaged parts, they should be replaced with new parts in time
