CNC Lathe CK61125E CK61140E CK61160E CK61180E CK61200E (1100mm Guideway)

Overview of CK61125E to CK61200E CNC Lathe Series

This extra heavy duty flat bed CNC lathe with 1100mm full-width guideway is a universal automated metal turning equipment custom-built for manufacturing plants handling oversized shaft and disc workpieces. Designed for factory production teams, processing workshops and metal fabrication workshops, the CK61125E-CK61200E lineup delivers stable micron-level precision under maximum 20-ton workpiece load, filling the market gap of high-load large-size turning equipment.

Equipped with interchangeable Fanuc or brand CNC control systems, hydraulic power turret and hydraulic tailstock as optional configurations, this 1100mm guideway CNC lathe supports continuous machining of internal/external cylinders, taper surfaces, complex rotary profiles and all standard metric & imperial threads. Unlike light-duty lathes, the whole machine adopts ultra-thick cast iron one-piece bed to eliminate cutting vibration during long-hour rough turning, which drastically lowers scrap rates for heavy metal components. The series covers swing-over-bed sizes from 1300mm to 2100mm, center distance adjustable from 3000mm to 10000mm, fully matching diverse large-part machining demands from power generation, shipbuilding and heavy machinery workshops.

Structural Design & Material Specifications

One-Piece High-Strength Cast Iron Bed for Max Rigidity

The core frame of this 20 ton load capacity CNC turning machine is integrally cast from high-density high-strength iron without split joints, which avoids structural deformation under heavy cutting force. Compared with spliced bed lathes, the integrated casting disperses workpiece pressure evenly across the 1100mm wide guideway, maintaining long-term geometric accuracy even after years of daily heavy-duty operation. This structure also supports full OEM/ODM customization on bed length and spindle power according to factory production schedules.

Ultrasonic Frequency Quenched Guideways with Turcite B Wear Protection

All linear guideways receive ultrasonic frequency quenching treatment, forming a hard wear-resistant surface layer to reduce abrasion from frequent carriage movement and cut down regular maintenance downtime. The contact surfaces between carriage and guide rail are pasted with Turcite B low-friction material, effectively eliminating sliding jitters and keeping consistent dimensional tolerance during repeated batch turning of large metal parts. This dual protection design extends guideway service life by over 40% versus ordinary non-quenched lathe guide rails.

Standard Heavy-Duty Power Matching Components

The standard 55kW main spindle motor provides stable low-speed high torque for hard alloy rough turning, paired with a 0.37kW coolant pump for uninterrupted cooling during long-cycle machining. The 4-position NC turret uses 50×50mm standard tool shanks, compatible with all common external turning, boring and threading tools, while the 280mm diameter hydraulic tailstock quill with 300mm travel offers reliable support for extra-long heavy shafts.

Industrial Applications of 1100mm Guideway Heavy CNC Lathe

Precision Large Machinery Component Production

Manufacturing workshops producing generator shafts, large hydraulic cylinder barrels and gear blanks rely on this large shaft plate workpiece CNC lathe for micron-level dimensional consistency. The low-vibration bed structure ensures smooth surface finish for automotive heavy-duty engine shafts, eliminating secondary grinding processes and lifting overall production efficiency.

Custom & Small-Batch Oversized Metal Parts Fabrication

For prototype workshops and custom metal processing factories, the programmable CNC system allows fast program switching to handle varied workpiece drawings without time-consuming manual tool adjustment. It suits low-volume customized turning of mold core blanks, mining equipment spindle sleeves and engineering machinery rotary components.

Mass Hardware & Heavy Fastener Manufacturing

Continuous automated operation supports high-output production of large threaded rods, heavy-duty flange nuts and connecting bolts. Steady spindle speed control guarantees uniform thread pitch, meeting strict assembly standards for construction and metallurgical equipment.

FAQ About CK61125E-CK61200E CNC Lathe Series

Can the machine match different CNC control systems?

Yes. We support optional Fanuc, Siemens and other mainstream CNC controllers; OEM adjustment on spindle, turret and automation accessories is fully acceptable for factory customized production lines.

What is the standard production lead time for one unit?

Standard production cycle takes 15-25 working days. If certain models are in finished stock, shipment can be arranged within 7 days after deposit confirmation. Lead time varies based on customized configurations and order quantity.

Where is your manufacturing base? Can production teams arrange factory inspection?

Our production workshop is located in Yishui County, Shandong Province, China. Global factory procurement teams are welcome to schedule on-site machine quality audits and live machining test demonstrations with advance appointment.

Is the 20-ton maximum load stable for long heavy shaft turning?

The integrated cast iron bed and 1100mm wide quenched guideway evenly distribute workpiece weight, with the hydraulic tailstock providing auxiliary support. Long-term customer feedback proves no bending or precision loss under rated full load during continuous 12-hour operation.
