What This Machine Does
The CW61125H/1 is the first frame in the H series of heavy duty turning lathes, running through CW61140H/1, CW61160H/1, CW61180H/1 and CW61200H/1 as the swing rises, with the model number indicating the class from 1250mm upward. These machines turn end faces, cylindrical surfaces and internal holes on large parts and cut metric, inch, module and pitch threads. The top slide can be powered on its own for a short taper, and a long taper is turned automatically by combining longitudinal carriage feed with top slide feed. Drilling, boring and trepanning are also within range, so a heavy part can have its holes produced in the same setting as its diameters. The series is built for power, high spindle speed and high rigidity, and it takes heavy cuts in ferrous and non-ferrous parts with carbon and alloy tooling. OEM builds and after-sales service are offered, which matters when a machine of this size is expected to stay in production for decades.

- Metric inch module and pitch threading for large screws and gear components
- High rigidity with high spindle speed for heavy cutting in ferrous and non-ferrous work
- OEM builds available where a plant needs a specific configuration
- After-sales service support for machines expected to run for decades
Where Heavy Duty Turning Lathe Machine CW61125H Earns Its Place
Problems It Solves
- Parts beyond workshop lathe capacity go outside at high transport and queue cost
- Long tapers cut in steps leave a stepped profile no drawing will accept
- Lifting a heavy part between lathe and boring mill loses alignment and takes crane time
- Standard configurations do not always match a plant's existing tooling and handling
- Heavy cuts with carbon and alloy tooling push a light machine off size
- Machines bought without service support become scrap when a single part fails years later
Who It Is For
- Steel mill and roll shop maintenance departments
- Heavy machinery builders needing large capacity turning in house
- Shipyards and marine shaft repair workshops
- Plant engineering contractors handling large rotating equipment
- OEM buyers specifying a heavy lathe to their own configuration
Application Scenarios
- Turning and facing heavy shafts rolls and cylinders
- Internal hole machining boring and trepanning on large components
- Long taper turning on tapered rolls and shafts in one pass
- Cutting large module and pitch threads on lead screws and gear parts
- Heavy roughing in ferrous and non-ferrous parts with carbon and alloy tooling
- Maintenance machining of plant components weighing up to the series limits

How It Is Built and What Can Be Changed
Operations Performed
- Turning
- End facing
- Taper turning
- Boring
- Drilling
- Trepanning
- Thread cutting
Quality Control
- Bed geometry checked over the full length of the frame ordered
- Headstock spindle run-out and rigidity verified under load
- Test taper cut to confirm the compound feed motion holds the angle
- Thread chart positions exercised across metric inch module and pitch
- Full running test before the machine is prepared for shipment
Customisation Options
- Frame selected from CW61125H/1 to CW61200H/1 by swing and part weight
- OEM configuration built where a plant needs a specific arrangement
- Workpiece length steady rest and chuck package specified with the order
- Supply voltage frequency and phase built to your site
- Export packing and case dimensions prepared for your shipping route
How It Compares With the Alternatives
| Heavy Duty Lathe CW61125D | The D and H series cover the same operations in different builds; send us part weight length and duty and we will recommend which series fits your work |
|---|---|
| Standard catalogue heavy lathe | OEM builds let the machine be configured around your existing tooling handling and plant layout |
| Boring mill for internal holes | Drilling boring and trepanning on the lathe hold the hole concentric with the turned diameter and avoid a crane lift between machines |
| Taper turning attachment | The compound feed motion turns a long taper automatically with no attachment to set up and no steps in the surface |
Running the Machine
Step 1
Confirm part diameter length and weight against the frame before ordering
Step 2
Install on a foundation designed for the machine and level the bed over its full run
Step 3
Set steady rests before roughing long or heavy shafts
Step 4
Use the powered top slide alone for short tapers and combined feed for long ones
Step 5
Check the taper angle on a test cut before committing the part
Step 6
Carry out boring and trepanning without unclamping the part wherever possible
Step 7
Follow the service schedule and keep spares for wear items on site

Questions About Heavy Duty Turning Lathe Machine CW61125H
Which H series frame do I need?
The frames run from CW61125H/1 to CW61200H/1 by swing class. Send us the maximum diameter, length and weight of your parts and we will confirm which frame to quote.
Do you build to a customer specification?
Yes. OEM builds are offered. Send us the configuration, tooling and handling arrangements you need and we will quote against them.
What after-sales support is there?
After-sales service is provided. Quote the model and the machine number on the plate when you need parts or technical support and we will trace it to the assembly records.
Can it cut long tapers?
Yes, automatically, by combining longitudinal carriage feed with top slide feed. Short tapers are cut by the powered top slide alone.
What materials is it built to cut?
Ferrous and non-ferrous parts under heavy cutting with carbon and alloy tools. Tell us the materials and we will advise the tooling package.
How is it packed and shipped?
Packed for sea freight from Xi'an on FOB CFR or CIF terms. Tell us the destination port and we will confirm case dimensions.
What are your payment terms?
30 percent by T/T on order and 70 percent before shipment, or an irrevocable L/C at sight.
