When we use CNC lathes in the production and machining industry, what is the reason for the imbalance of the workpieces processed by CNC lathes?
The following editor will explain in detail for you.
1. The size of the workpiece is accurate, and the surface finish is poor
Problem factors: the cutting edge of the
CNC blade is damaged and not sharp; the CNC lathe has resonance and the
placement is unbalanced; the CNC lathe has a creeping condition; the machining
procedure is wrong.
Solution: The CNC blade is damaged,
re-sharpening or choosing a better CNC blade; the CNC lathe produces resonance
or unbalanced placement, and needs to adjust the horizontal plane to maintain
balance; the factor of mechanical creep is the damage of the pallet guide rail,
and attention should be paid to maintenance. Clean the iron wire in time, and
add lubricant on time; choose the coolant suitable for the production and machining
of the workpiece, and choose the higher spindle bearing speed as much as
possible when the production and machining regulations of other processes can
be met.
2. The condition of the taper and size of the workpiece
Problem factors: The horizontal plane of
the CNC lathe is not adjusted properly, the height is uneven, and the placement
is unbalanced; when turning the long axis, the CNC blade eats the tool deeper,
resulting in a tool yield; the tailstock thimble is not concentric with the
spindle bearing.
Solution: Use a level to adjust the level
of the CNC lathe, lay a solid foundation, and determine the CNC lathe to
improve its resistance; choose an effective process and appropriate cutting
feed to avoid the force of the CNC blade to make the knife; CNC lathe adjusts the
tailstock .
3. The driver position light is normal, but the size of the workpiece produced is sometimes large or small
Problem factors: the CNC lathe pallet runs
at high speed for a long time, causing damage to the screw and bearing; the
continuous positioning accuracy of the tool holder causes errors in the
long-term application; the pallet can accurately return to the starting point
of production and machining every time, but the workpiece is produced and
processed The size is still changing. Such problems are usually caused by the
spindle bearing. The high-speed rolling of the spindle bearing causes severe
damage to the bearing, resulting in changes in the production and machining
dimensions.
