CNC lathe spindle ladder is a hollow shaft, is refers to the driven on nc lathe chuck clamp (
Artifacts)

Or tool rotation axis, generally by the main shaft, bearing and transmission parts (
Gear or pulley)
And so on.

CNC lathes have spindle assembly, generally as long as a main shaft, some have more than two main shaft, such as the Venus machine produce of double spindle automatic processing unit is two main shaft, JXM6308 as many as eight motorized spindle.

Numerical control lathe spindle generally equipment in bedside cabinet, occupy larger, is supported by two or three sets of bearings.
The greater the diameter thickness under equal information, rigid, the better.

On the basis of material mechanics analysis, when after shaft transmission torque, the higher the hollow shaft transmission torque of useful results.

When CNC lathe spindle demand big torque, demand more thick shaft diameter.

Because of the influence of the axial part of the torque is small, so the general use of hollow to reduce the weight of the axis of rotation.

Small CNC lathe spindle hole - 42 mm in diameter

Select suitable spindle hole is 82 mm, can convenient equipment hydraulic clamping and feeding the organization.


Zhongshan JSTOMI CNC Machine Tool Co., Ltd. have now make a decision to enlarge our company in other countries.

Zhongshan JSTOMI CNC Machine Tool Co., Ltd. 's main technology of cnc service leads us to understand and utilize information correctly.
Zhongshan JSTOMI CNC Machine Tool Co., Ltd. might focus its marketing efforts by highlighting its end product—improved technology and increased profits—not its producing methods.

With a tilt is casting lathe bed CNC lathe, and a larger bearing section, so it has good rigidity and damping, and can ensure the precision of processing.

The machine tool main drive system adopts ac servo motor, spindle parallel driven directly by the v belt.
Avoid the problem of gear box chain caused by noise.


slant bed CNC lathe driving screw is high precision ball screw, the screw and nut between the transmission gap is very small, also cannot say that there is no gap, but as long as there is gap, when the screw in one direction and then reverse transmission, it is hard to avoid can produce recoil, with the reverse clearance affects the repositioning precision of numerical control lathe, so as to affect the machining accuracy.

Tilt with the layout of the lathe bed CNC lathe will directly affect the clearance on the ball screw in the X direction.

Gravity directly along the screw axial movement, causes the driver when the backlash is almost zero.

Numerical control lathe with a flat bed X direction of the screw is not affected by axial gravity, and can't eliminate clearance directly.

This is the inherent accuracy of CNC lathe tilting table design advantage.



inclined guide rail machine adopts mechanical and electrical integration design, the bottom of the bed and feet for the whole structure, bed lean back 30 degrees, compact structure, strong rigidity, good shock resistance, easy clearance.

Spindle adopts the spindle unit, inverter or servo motor, the spindle rotational speed is high and can realize the infinite speed adjustment, guide adopts imported high precision linear rolling guide, driven by ac servo motor, high positioning accuracy, moving speed, guide rail adopting centralized automatic lubrication device and the protection, lubrication is sufficient, safe and long service life.



inclined guide rail machine tools installation and use:
1, in order to ensure the working accuracy of machine tool, when installation, adjustment or anchor bolt support, guarantee the machine level, don't have distorted the guide rail.


2, installation and debugging work is done, you must first check whether flexible rotation part and electric circuit is reliable, and then run the test, the test time is less than 2 hours, to determine the normal rear accessibility test processing.


3, oblique guide spindle bearings used in machine tools can produce clearance after a period of time, the user can adjust according to the use of speed.
Gap is too small, easy to cause bearing heating;

Clearance is too large, it will affect the precision of the workpiece's surface roughness.

On the main shaft bearing before and after the lock nut elastic adjustment, bearing clearance in a 0.
006 mm is preferred.


4, machine tool, drag the size of the plate are equipped with iron, use after a period of time can be adjusted by adjusting the plug iron to large and small plate gap, should be flexible to run, do not affect the machining accuracy is advisable.


5, oblique guide rail lubrication, sliding parts must fully machine per shift (
In 8 hours)
2 - should be filling machine oil
Four times, bearing lubrication should be per 300 -
-
Replaced every 600 hours.


6, at ordinary times should be to do a good job of machine maintenance and cleaning.


7, machine tool should be read before use machine operation instruction.
