Countermeasures for Handwheel Failure of CNC Machining Center
As a processing equipment, the CNC machining center will inevitably have some artificial problems or malfunctions during the machining process. This time we are mainly talking about the causes of the failure of the CNC machining center handwheel and the corresponding solutions.
High Density Fiberboard is well known for its enhancing the interior decoration,especially for commercial use area.
Decorative paper finish and core base material, high density moisture proof board.Compare with traditional wall coverings,it's anti-scratch and waterproof,and most importantly it's easier and cheaper to install than those.It's very popular with global market.
As a processing equipment, the CNC machining center will inevitably have some artificial problems or malfunctions during the machining process. This time we are mainly talking about the causes of the failure of the CNC machining center handwheel and the corresponding solutions. 
the reason:
1. Poor contact of the handwheel shaft selector switch
2. Handwheel magnification selection switch is in poor contact
3. Handwheel pulse disk damage
4. Handwheel cable broken
solutions:
1. Enter the system diagnosis and observe the corresponding contact condition of the axis selection switch (the connection line is in good condition), if it is damaged, replace it.
The switch can be solved
2. Enter the system diagnostic observation magnification switch corresponding to the contact condition (the connection line is in good condition), such as damage replacement
The switch can be solved
3. Take off the pulse disk to measure whether the power supply is normal, and whether the resistance between + and A, + and B is normal. Such as damage
replace
4. Enter the system diagnostics to observe the corresponding contacts of each switch, and then measure the axis selection switch, override switch, pulse
Whether the contacts of the connecting line between the punching discs are connected to the corresponding points of the system terminals, such as breaking and replacing 
The speed machining CNC machining center adopts high-end imported accessories, which has strong rigidity and stable performance, and witnessed by many users. support hotline
