The CKL series flat bed CNC lathe with 1100mm wide guide rail is a versatile heavy-duty automated metal processing machine engineered for medium-load large shaft and disc component machining, targeting fabrication workshops, mold manufacturing plants and aerospace component processing facilities. Different from the E-series 20-ton heavy-load model, this lineup caps maximum workpiece load at 10 tons, balancing rigid performance and cost control for mid-scale production teams with regular oversized turning requirements.
This 10 ton load industrial CNC turning machine realizes full rotary surface machining coverage, including internal/external cylinders, precise conical profiles, irregular curved rotary surfaces and multi-spec industrial threads. Every unit retains the signature high-rigidity flat bed architecture while optimizing motor power, tailstock structure and overall machine footprint to reduce workshop space occupation. Spindle speed ranges from 10-300rpm for CK61125L-CK61160L and 0-200rpm for CK61180L/CK61200L, matching light rough cutting and fine finishing of alloy steel, cast iron and aluminum oversized workpieces. Complete tailor-made service covers spindle bore, bed length, control system and auxiliary automation to align with unique workshop production workflows.
The one-piece cast iron base eliminates assembly gaps that trigger cutting vibration, delivering stable machining precision during repeated medium-load turning tasks. The flat horizontal bed layout evenly bears workpiece weight, which greatly reduces tool wear during continuous mass production. Our internal engineering team can adjust bed wall thickness and overall dimensions to meet customized load and size requirements from processing plant operators.
1100mm full-width guide rails undergo ultrasonic frequency quenching to form a hard anti-abrasion surface, lowering maintenance frequency and extending machine service life. Turcite B composite material is applied to carriage-guide rail contact areas to minimize sliding friction, preventing sudden position offset during precision fine turning and maintaining consistent tolerance after thousands of production cycles. This design avoids frequent guide rail grinding and replacement for long-term factory use.
CK61125L-CK61160L adopt 30kW main spindle motors, while CK61180L and CK61200L upgrade to 37kW spindle motors for higher torque on thick-wall workpieces. The 0.25kW energy-saving coolant pump cuts power consumption during non-stop production. The 260mm diameter tailstock quill with Metric 80 taper and 300mm travel provides stable support for long shafts within the 10-ton load limit, paired with a standard 4-position NC turret with universal 50×50mm tool shanks.

Hydraulic cylinder barrels, conveyor drive shafts and tapered bearing sleeves are core processing targets for this custom heavy-duty metal turning lathe. Consistent internal/external cylindrical precision ensures tight fit between pistons and cylinder bodies, widely used by hydraulic equipment manufacturing factories.
Aerospace engine tapered connectors and medical prosthetic rotary parts require ultra-stable surface finish. The programmable CNC system supports complex irregular curved surface turning, meeting the ultra-high tolerance standards of precision component workshops with small customized batch orders.
For medium-scale ship accessory workshops and hydroelectric equipment factories, the machine handles medium-weight valve bodies, generator intermediate shafts and large threaded connectors. The 1100mm wide guide rail guarantees smooth long-shaft turning without vibration under rated load.
Our professional engineering team delivers full tailored solutions: adjustable bed length, optional servo/hydraulic tailstock, interchangeable CNC control systems, extra steady rest installation and customized spindle power to match factory machining materials and workpiece dimensions.
Operators must inspect lubrication systems before startup, select matched cutting parameters based on workpiece materials, stop the machine fully before measuring parts, and clean chips and lubricate guide rails after daily production to extend service life and retain machining accuracy.
All machines pass CE, ISO, TUV and SGS industrial quality certifications, fully meeting production equipment safety and precision inspection standards for global metal processing plants. Complete certification documents can be provided for factory equipment import declaration.
The CKL series supports a maximum 10-ton workpiece load with smaller overall dimensions and lower power consumption, ideal for medium-load regular oversized parts. The CK61E series reaches 20-ton max load with thicker cast iron beds and higher spindle power, built for ultra-heavy large workpieces in heavy machinery and mining equipment factories.
