CNC Turning Line
CNC Lathes
Turning is decided by the part, not the brochure. Long shafts and heavy disc work want a level bed with a long travel and a tailstock you can trust. High-volume production wants a 45° slant bed that sheds chips, keeps the tool close to the spindle and holds repeatability across a full shift. This range covers both, from a 400 mm swing flat-bed to a 7.5 kW slant-bed turning platform.

How These Lathes Are Built
Cast Bed, Hardened Ways, Preloaded Screws
Every machine in this range follows the same turning logic: a rigid cast bed carries the saddle, a preloaded ball screw drives each axis, and a high-precision spindle bearing set holds the workpiece without chatter. What changes across the range is the bed angle, the spindle bore, the turret and the control.
- Bed and guidewaysFlat-bed models use wear-resistant cast iron ways hardened and ground to hold geometry over years of cutting; slant-bed models use hardened Taiwan linear guides on a 45° ribbed bed.
- Ball screws and drivePrecision ground ball screws on both axes with servo drives, giving fast traverse and repeatable positioning without backlash.
- Spindle unitHigh-precision rolling bearing sets, dynamically balanced and precisely assembled for high speed, low noise and strong rigidity.
- Turret and toolingFour-station electric tool post on the flat-bed machines, eight-station servo turret or gang tool post on the slant-bed machines.

Accuracy and finish figures are published for the BR-500 and are verified by a geometric test on every machine before shipment. Where a value is not published for a model it is left open here and confirmed against your drawing rather than assumed. Spindle bore, chuck, turret, tailstock, chip conveyor and control are all specified per order.
Bed Structure Comparison
Flat Bed or 45° Slant Bed?
The bed angle is the single biggest difference in how a lathe behaves day to day. It decides chip flow, access, rigidity under load and how the machine fits into a production cell.
Flat-Bed Structure (CK6140 / CK6160)
A level, ribbed cast iron bed with hardened and ground slideways and a widened saddle. The horizontal layout takes long shafts between centres, handles heavy interrupted cuts, and keeps the whole workpiece visible to the operator. Best when parts are long, heavy, or changed often.
45° Slant-Bed Structure (TCK6340 / BR-500)
A 45° integral bed with enlarged linear guideways. Gravity clears chips away from the cutting zone, the saddle sits closer to the spindle for higher rigidity, and the operator reaches the spindle nose for fast loading. Best for high-volume, small and medium parts.
Machining Range
What Each Layout Reaches
Read travel, swing and bar capacity together before choosing. Swing sets the largest disc, travel sets the longest shaft, and bore sets the largest bar fed through the spindle.
- Long shaftsChoose a flat-bed with the longest centre distance. CK6140 and CK6160 reach 750 to 2000 mm between centres with a 130 mm tailstock quill.
- Large discs and ringsChoose by swing and cross-slide clearance. The CK6160 swings 600 mm over the bed and 350 mm over the cross slide.
- Bar-fed productionChoose by spindle bore. The BR-500 passes 62 mm bar and the TCK6340 passes 45 mm, both with hydraulic chucks for fast cycles.
- Weldment and castingsChoose a slant bed with a servo turret and high rapid rates to keep chip-to-chip time low on heavier stock.
Where These Lathes Run
Turning That Feeds Assembly Lines
The same turning platform serves job shops and high-volume plants. The layout and turret decide which one fits.
Pumps, Valves & Fittings
Bodies, flanges, stems and threaded ends turned with repeatable threads, radii and tapers, ready for assembly without hand fitting.
Bearings & Gear Blanks
Ring and disc parts held to tight runout and finish, with heavy-cutting spindle units handling the stock removal before a finishing pass.
Automotive & Motorcycle
Shafts, bushings and small housings produced in volume, where a slant bed with hydraulic chuck and servo turret keeps cycle time and consistency in check.
FAQ
CNC Lathe Questions
Flat-bed lathes like the CK6140 and CK6160 keep a level bed with a long travel, which suits long shafts between centres, heavy interrupted cuts and disc work where the operator needs to see the whole part. Slant-bed lathes like the BR-500 and TCK6340 use a 45 degree bed so chips fall away from the cutting zone and the tool can move closer to the spindle. That gives faster chip-to-chip time, better rigidity on high-speed turning and cleaner thermal behaviour in production.
The flat-bed models carry an electric four-station tool post with 25 by 25 mm tools and a manual chuck as standard, available with a larger 80 mm spindle bore. The slant-bed models carry an eight-inch hydraulic chuck on a hollow A2-6 or A2-5 spindle nose, a servo turret on the BR-500 and a gang tool post with an optional hydraulic turret on the TCK6340, plus a hydraulic tailstock for shaft work.
The BR-500 publishes 0.01 mm positioning accuracy on both axes and 0.006 mm repeat positioning accuracy, holding IT6 machining accuracy and a surface roughness of Ra 0.8 or better. The other models are built on hardened and ground guideways or preloaded linear guides with precision ball screws and are geometrically tested before shipment. Send your part drawing and tolerance and we confirm the achievable result.
All four machines turn carbon steel, alloy steel, stainless steel, cast iron and non-ferrous bar and castings. The CK6140 swings 400 mm over the bed, the CK6160 600 mm, and both take 52 mm bar as standard. The slant-bed lathes handle disc parts to 320 mm and shaft parts to about 260 mm, with bar capacity to 62 mm on the BR-500 and 45 mm on the TCK6340.
The turning range is delivered with GSK control as standard on the CK6160, BR-500 and TCK6340, with Siemens, Fanuc and Mitsubishi available as options on the slant-bed models. Control choice is matched to your operator skill level and to the programs you already run, and every machine ships with an English interface and parameter set.
Standard builds ship in roughly 30 to 45 working days, and customized bore, turret, control or bar-feeder configurations take a little longer. Each 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.
