Why is it called CA6140?

 

 

 

 

C stands for lathe,

A is the structural feature code to distinguish C6140, which can be understood as an upgraded model.

6 stands for horizontal,

1 represents the basic type,

40 represents the maximum rotation diameter.

For the specific structure, take a look at the hand drawing

1. Outer body of machine tool

 

 

 

 

 

The names of each component indicated by the numbers in the figure are as follows:

1. Spindle box, 2. Tool post parts 3. Tailstock 4. Bed 5. Lead screw 6. Smooth bar 7. Right leg 8. Slide box 9. Left leg 10. Feed box

 

 

CA6140 Ordinary Lathe is a universal machine tool with ordinary precision. It is suitable for machining internal and external rotating surfaces on various shafts, sleeves and disc parts, as well as turning end faces.

 

 

Threading, drilling, reaming, knurling, etc. can all be processed. Of course, as we said before, it can be modified for non-turning processing.

 

 

 

 

2. Spindle drive

 

M1 is a two-way multi-plate friction clutch that can rotate the main shaft forward, reverse and stop, and M2 is a gear clutch

The function of the spindle drive system is to transmit the motion of the power source (motor) to the spindle, so that the spindle drives the workpiece to realize the main rotation movement, and the spindle can be changed and reversed

 

 

3. Assembly drawing of spindle assembly

 

 

 

1. Spindle 2. Round block 3. Tapered hole double row radial short cylindrical roller bearing 4. Round nut 5. Straight tooth cylindrical gear 7. Tapered hole double row radial short cylindrical roller bearing 8. Single row radial Short cylindrical roller bearing 9. Helical cylindrical gear 11. Double row radial thrust ball bearing, M2 gear clutch
