What This Machine Does
The CS6140J belongs to the CS6140 series of universal lathes, the general-purpose size in the range that most shops reach for first. It turns internal and external diameters, cuts tapers, faces ends and handles the rest of the rotary work that passes through a jobbing shop, and it also drills, bores and broaches grooves, so a part can often be finished without being moved to another machine. Threading covers inch, metric, module and D.P. pitches. The spindle has a through-hole bore so bar stock of larger diameter can be held in the headstock rather than clamped out in front of the chuck. Both inch and metric measuring systems are fitted, which removes the conversion step for shops working from drawings in either standard. Buyers choose hand brake or foot brake, and the machines are built for 220V, 380V or 420V supply at 50Hz or 60Hz, so the same model suits markets with different power.
Why Buyers Choose This Machine
- One machine covers turning taper turning end facing drilling boring and groove broaching
- Inch metric module and D.P. threading without changing the gear train
- Through-hole spindle bore holds larger bar stock inside the headstock
- Inch and metric dials both fitted so no drawing conversion is needed at the machine
- Hand brake or foot brake chosen by the buyer to suit shop practice
- Built for 220V 380V or 420V at 50Hz or 60Hz for different export markets
- General-purpose 14 inch class capacity that suits most jobbing shop work
Where CS6140J Universal Lathes Earns Its Place
Problems It Solves
- Moving a part between lathe drill and slotter loses the original concentric setup
- Module and D.P. thread work normally requires a dedicated change gear set
- Converting between inch and metric dials during a job introduces mistakes
- Small spindle bores limit the bar diameter a shop can run
- A machine built for one voltage cannot be resold or relocated across markets
- Operators differ on braking preference and a fixed choice slows one shift or the other
Who It Is For
- Jobbing and repair shops needing one universal lathe for mixed work
- Maintenance departments turning replacement parts in house
- Shops working from both inch and metric drawings
- Training workshops teaching general turning and threading
- Machinery dealers supplying markets with different voltages and frequencies
Application Scenarios
- Internal and external turning of shafts bushes and housings in a jobbing shop
- Taper turning and end facing on rotary components
- Drilling and boring holes on parts already set up in the chuck
- Groove broaching in bores without moving the part to a slotting machine
- Cutting module and D.P. threads for gear and worm repair
- Bar-fed short batch turning through the spindle bore

How It Compares With the Alternatives
| Gap Bed Lathe Machine CS6240 CS6250B/C CS6266B/C | The CS6240 and above are the larger frames in the same family; the CS6140J is the general-purpose size for a shop whose work is mostly medium shafts and housings |
|---|---|
| Lathe with metric threading only | Inch module and D.P. pitches are on the CS6140J chart, so gear and imperial repair threads do not need extra change gears |
| Turning and then moving the part to a drill press | Drilling boring and groove broaching happen on the lathe, which keeps the bore concentric with the turned diameter |
| Single-voltage imported machines | 220V 380V or 420V at 50Hz or 60Hz means one specification covers most export markets |
Running the Machine
Step 1
Confirm the machine is wired for your supply voltage and frequency before first start
Step 2
Level the lathe on its foundation and check the bed for twist
Step 3
Work from either the inch or the metric dial set and stay with one system per job
Step 4
Pass bar through the spindle bore only when it is supported and guarded behind the headstock
Step 5
Select the thread system and pitch on the chart before engaging the lead screw
Step 6
Use drilling boring and broaching setups while the part is still chucked to keep concentricity
Step 7
Test the brake at the start of each shift and keep the ways lubricated
