What This Machine Does
The CK5225 is the CNC version of the C52 double column vertical lathe, offered with the CK5231 and CK5240 as diameter increases. It covers internal and external turning, internal and external tapering, facing, slotting, threading and contour surface turning, the last of which is only practical under CNC control. The spindle drive uses servo motors through a two-step speed changing unit, so the table runs with stepless speed regulation rather than fixed gears. Wear is addressed where it actually happens: the vertical beam rail and ram guideways are super audio quenched to HRC 50 or above and the sliding surfaces carry a laminating treatment on both the swash plate surface and the iron mask, which is what holds accuracy and is stated to extend the overhaul period beyond ten years. The machine handles rough and fine turning of cylinders, round dimensional surfaces, ends and grooves across all sectors of machining.
Why Buyers Choose This Machine
- CNC control adds contour surface turning that a manual vertical lathe cannot produce
- Servo spindle drive through a two-step unit gives stepless table speed regulation
- Beam rail and ram guideways quenched to HRC 50 or above resist the wear that ends accuracy
- Laminating treatment on sliding surfaces including swash plate and iron mask preserves precision
- Overhaul period extended beyond ten years by the guideway treatment
- Rough and fine turning on the same machine so a part is finished in one setting
- Three frames CK5225 CK5231 and CK5240 covering rising diameters
Where CK5225 Double Column Vertical CNC Lathe Machine Earns Its Place
Problems It Solves
- Contoured and profiled surfaces cannot be turned repeatably by hand on a manual vertical lathe
- Fixed gear table speeds cannot hold surface speed as the tool moves across a large face
- Untreated guideways wear and the machine loses accuracy long before its structure is worn out
- Rough and fine turning split between machines introduces concentricity error
- Operator-dependent results in vertical turning vary between shifts
- Frequent overhauls of a large vertical machine take it out of production for weeks
Who It Is For
- Manufacturers of profiled rings discs and housings needing repeatable contours
- Wind energy pressure vessel and heavy machinery producers
- Shops moving from manual vertical turning to programmed production
- Plants that measure machine value by overhaul interval and accuracy retention
- Importers supplying CNC vertical turning capacity
Application Scenarios
- Contour surface turning of profiled discs and rings under CNC control
- Internal and external tapering of conical seats and housings
- Facing slotting and threading on large circular parts
- Rough and fine turning of the same casting in one setting
- Production batches where table speed has to change with diameter through the cut
- Machining across mixed sectors where part profiles change frequently

How It Compares With the Alternatives
| Manual Vertical Turret Lathe C5225 | Same double column family and frame size, but the CNC build adds contour surface turning servo drive and stepless table speed, and repeats a profile part after part |
|---|---|
| Vertical lathe with geared table drive | Servo drive through a two-step unit holds surface speed as the tool crosses a large diameter, where gears force a compromise |
| Untreated guideway machines | Quenching to HRC 50 or above plus the laminating process on sliding surfaces is what keeps the machine accurate and pushes the overhaul interval past ten years |
| Splitting roughing and finishing across two machines | Rough and fine turning in one setting on the CK5225 removes the re-clamping error between the two operations |
Running the Machine
Step 1
Clamp the workpiece on the table and check run-out before the first program run
Step 2
Load or write the program for the profile including rough and fine passes
Step 3
Let the servo drive set the table speed for each diameter rather than fixing one speed
Step 4
Prove the contour on the first part and inspect before running the batch
Step 5
Keep roughing and finishing in the same setting to preserve concentricity
Step 6
Keep the guideway sliding surfaces clean so the laminated surfaces are not scored by chips
Step 7
Follow the lubrication and CNC maintenance schedule to protect the overhaul interval

Questions About CK5225 Double Column Vertical CNC Lathe Mach
What does the CNC version add over the manual C5225?
Contour surface turning, servo spindle drive with stepless table speed, and repeatable programmed cycles. A manual machine cannot hold a profiled contour part after part.
Which frame should I order?
CK5225, CK5231 and CK5240 differ in diameter capacity. Send us your maximum part diameter, height and weight and we will confirm the frame.
How hard are the guideways?
The vertical beam rail and ram guideways are super audio quenched to HRC 50 or above, with a laminating treatment on the sliding surfaces.
How long between overhauls?
The guideway treatment is stated to extend the overhaul period beyond ten years in normal service. Actual intervals depend on your duty and maintenance.
Which CNC system is used and in what language?
The control and operating language are set with the order. Tell us what your operators and maintenance team already support.
What foundation and shipping arrangements are needed?
We supply the installation and foundation drawing for the frame ordered, and the machine is shipped for sea freight from Xi'an on FOB CFR or CIF terms.
What are your payment terms?
30 percent by T/T on order and 70 percent before shipment, or an irrevocable L/C at sight.
