In the process of using a CNC lathe, it is very dangerous if the hand cranked pulse generator encounters abnormalities. Its main work is zero position correction and signal segmentation. If

abnormalities occur, it will cause inaccurate filling or signal segmentation failure, which will result in serious accuracy errors in the processed parts and cause production and processing

failures. Today, our CNC lathe manufacturer Haishu will explain to you the reasons for the abnormal use of the hand cranked pulse generator in CNC machine tools.
If it's new, check if the connection

between the motor and the screw is not good. Also, if there is a buzzing sound when the servo motor moves, it's mostly due to the motor gain being too high. This is a new problem with the old

equipment. You need to consider whether it's a collision, mostly due to the screw bending. Also, if there is any noise from manual operation, please supplement. Your feedback is that the motor is

receiving a step signal. The electronic handwheel hand cranked pulse generator is used to control CNC machine tools. When manually feeding, the hand cranked pulse generator emits a single step

pulse, which is synchronized with your hand. When you shake an angle, the machine moves accordingly, and the feed value per degree is related to the set multiple. Mainly used for teaching CNC

mechanical work origin setting, zero position correction and signal segmentation of CNC machine tools, printing machinery, etc., as well as step-by-step fine-tuning and interrupt insertion actions.

When the handwheel rotates, the encoder produces a signal with the hand.
A dial gauge or dial indicator is mounted on the spindle or baffle to reset the needle in the transverse direction of the

tool holder. The hand cranked pulse is reset in the X direction, and the needle is rotated upwards and then returned to zero repeatedly. This is a simple method to pay attention to correcting the X

gap. The dial gauge or dial indicator is mounted on the spindle or baffle, and the needle is rotated in the X direction by hand shaking the pulse in the vertical direction of the tool holder.

Encoders are generally used on motors or measured shafts to measure rotational information (speed, position, angle, etc.). Hand cranked pulse generator is used to provide pulse output. Users use

hand cranking to generate pulses, which are generally used to drive motors in manual mode. The principle of the two is the same. Both machine tools and some instrument products need to be installed

and debugged before use. The correctness and rationality of installation and debugging largely determine whether this CNC machine can achieve normal economic efficiency and its own service life,

which is a must face for both CNC machine manufacturers and user factories.
The above are the reasons for the abnormal use of the hand cranked pulse generator in CNC machine tools. We hope that the

above explanation can be helpful for everyone when using CNC lathes in the future.
