Wide-Swing Flat-Bed Turning
Flat-Bed CNC Lathe CK6160
When the parts get bigger but the shop still wants a level-bed layout, the CK6160 is the step up. It opens the swing to 600 mm over the bed and 350 mm over the cross slide, raises spindle torque, and adds the details that matter over a long service life: high-frequency hardened guideways, brand-name ball screws and forced automatic lubrication with a low-oil warning.

High Spindle Torque
Torque and rigidity are raised to match the larger swing, so the machine holds its setting on disc parts and heavier stock.
Stable and Reliable
The platform is built for stable performance and good accuracy retention, which is what a production turning shop needs.
Compact Envelope
A refined bed design keeps the machine compact for its swing, so it fits into a shop without an oversized footprint.
An Optimised Bed
More Swing Without More Machine
The CK6160 shares the flat-bed philosophy of the range but the bed is optimised for larger disc and shaft parts. The result is a compact machine that still offers 600 mm of swing and a strong, quiet spindle.
- Optimised bed designThe bed is shaped to carry the larger swing while staying structurally stiff under cut.
- Disc and shaft workThe layout suits both: large flanges and rings on the face, stepped shafts between centres.
- Thread and contour turningStraight lines, arcs, and metric and imperial threads including multi-start forms.
- Familiar operationA level-bed layout and manual chuck keep setup and tool changing straightforward.

The source datasheet for the CK6160 lists the mechanical specification above and confirms GSK control, brand-name ball screws and high-precision screw bearings. Positioning and repeat positioning accuracy are verified by a geometric test on each machine before shipment rather than quoted as a single figure. Spindle bore, chuck, spindle speed form and bed length are all specified per order.
Bed Structure and Care
Why the Guideways and the Oil Last a Long Time
Two features carry the CK6160 over years of production: how the guideways are made, and how they are lubricated. Both are designed so accuracy does not depend on the operator remembering.
01
Hard Guideways
The bed and saddle guideways use a special hard material, high-frequency hardened, so they resist wear and keep machining accuracy good over a long life.
02
Precision Spindle Set
A high-precision bearing set is precisely assembled and dynamically balanced, giving accuracy, low noise and strong rigidity.
03
Brand-Name Ball Screws
Well-known brand ball screws with high-precision screw bearings give dependable positioning on both axes.
04
Forced Automatic Lubrication
Oil is delivered to the screws and guideways at fixed points in fixed quantities, with a warning signal if oil runs low or a fault appears.
Core Strengths
Built to Stay Accurate in Production
Six published characteristics of the CK6160, and what each one means on the shop floor.
Compact and Well Proportioned
A refined bed keeps the machine compact for its swing, so it sits comfortably in a normal turning bay.
High Torque, High Rigidity
The spindle is built for torque and rigidity, which is what allows the larger parts to be cut without chatter.
Stable Performance
The machine is designed for stable, reliable running and good accuracy retention rather than peak figures on paper.
Hardened, Wear-Resistant Ways
High-frequency hardening gives the guideways the hardness and wear resistance that keep geometry in tolerance.
Quiet, Accurate Spindle
Precise assembly and dynamic balancing of the bearing set reduce noise and raise rotational accuracy.
Protected Lubrication
Forced lubrication with an automatic warning signal protects the screws and guideways between services.
Operating Cycle
From Chuck to Finished Part
The routine follows the level-bed layout: clamp, set, run, check.
01
Clamp the Workpiece
Load disc or shaft parts in the manual chuck, or feed bar through the 52 mm bore, then support the end on the tailstock.
02
Set the Tools
Load the four-station tool post with 25 by 25 mm tools and enter the offsets for the job.
03
Run the Program
GSK control runs the profile and any threads, with rapid moves of 6000 and 8000 mm per minute between features.
04
Measure and Release
Check the first part against the drawing and run the batch; hardened ways and forced lubrication hold the setting.
Where It Earns Its Place
Larger Discs and Shafts, Familiar Operation
The CK6160 suits shops that need more swing and torque without moving to a different machine layout.
Flanges, Rings & Housings
Larger disc parts faced, bored and turned outside diameter within the 600 mm swing, ready for drilling or assembly.
Stepped Shafts
Shafts turned between centres on the MT5 tailstock, with tapers, radii and threads cut in one program.
General Engineering
Mixed turning work where the wider swing and higher torque replace a second machine for the larger parts.

FAQ
CK6160 Lathe Questions
The CK6160 suits disc parts and shaft parts. The optimised bed gives a 600 mm swing over the bed and 350 mm over the cross slide, so flanges, rings and housings fit comfortably, while the same machine turns straight and stepped shafts. It also cuts straight lines, arcs, metric and imperial threads and multi-start threads.
The spindle uses a high-precision bearing set that is precisely assembled and dynamically balanced, which delivers high accuracy, low noise and strong rigidity. The bed and saddle guideways are made from a special hard material, high-frequency hardened for high hardness and wear resistance, so machining accuracy is held over a long service life.
It supplies oil to the ball screws and guideways at fixed points in fixed quantities, so lubrication does not depend on an operator remembering to do it. If an abnormal condition or an oil shortage is detected, the system raises a warning signal automatically, which protects the guideways and the accuracy of the machine.
The machine uses GSK CNC control, together with brand-name ball screws and high-precision screw bearings. The combination gives reliable positioning and repeatable motion on both axes, and the control ships with an English interface and parameter set.
A brand-name manual chuck is fitted as standard, and the spindle has a 52 mm bore with an 80 mm option. An electric four-station tool post takes 25 by 25 mm tools, and the tailstock has a 65 mm quill on an MT5 taper with 130 mm of travel for supporting shaft work.
Standard builds ship in roughly 30 to 45 working days, with the 80 mm bore, stepless spindle or longer bed adding to that. Every machine is assembled, aligned and trial cut before packing, and we provide English manuals, a parameter file, video commissioning and remote operator training, with lifetime support after delivery.
