Versatile Heavy-Duty Turning Lathes for Enhanced Production Efficiency

Product Description

Machine Picture
Machine Introduction
CK61125 Heavy-Duty Turning Lathes is a multifunctional CNC lathe developed on the basis of a large horizontal flat bed lathe. The bed is re optimized with the increased overall weight, lengthened, widened and thickened pallet, and the processing efficiency, accuracy and rigidity are better than ordinary CNC lathes.
Adopting a semi protective structure and equipped with a GSK 980TDi system. The main transmission of turning is automatic four speed continuously variable transmission, with two linked control axes.
The X and Z axes use ball screw pairs, AC servo motors, and precision reducers to achieve servo movement and semi closed loop control, with good positioning accuracy and repeatability.

This machine tool mainly consists of a bed body, headboard box, headboard box base, main motor and motor base, chuck, closed center frame, tailstock, tool holder, walking platform, hydraulic system, electrical system and CNC system, cooling system, functional components and random accessories.
Machine Applications
This machine tool is mainly capable of processing various internal holes, external circles, conical surfaces, circular arc surfaces, and threads within its processing range, and is particularly suitable for rough and precision machining of small and medium-sized shaft and disc parts.
Medium and large oil cylinders
Full process machining of wind turbine spindle
Drums in the paper industry
Crane wire rope drum
Cathode rod drum
Centrifuge drum
Efficient turning processing of precious metals such as high-temperature alloys, titanium alloys, steel ingots, rolling rolls, and laser cladding materials
Processing of thin-walled parts through processes such as external turning, internal boring, end face drilling, tapping, axial drilling, milling, etc

Machine Features
All HT300 castings bed frame, weight are 9500/ton;
Lengthened, thickened, and widened pallet slider, weighing 300 kilograms more than conventional products;
Can be equipped with a boring force seat for turning inner holes with a length to diameter ratio of 6:1 or less, with a single side of 5mm without vibration force for rough turning and up to 1.6 for fine turning.
Taking a processing length of 3 meters as an example, the total length of the bed is 5.7, and the length of the processed workpiece can reach 3 meters (taking the 3m specification as an example)
The headboard box is equipped with a hydraulic automatic four speed system (with a hydraulic station), weighing 1.6 tons, which is 200 kilograms heavier than the national standard.
Two units of 45 size linear auxiliary guide rail plus one box rail, ensuring that the tool does not vibrate when turning the maximum outer circle, and the cutting amount is large, ensuring accuracy.
The spindle diameter jump and end jump are both 0.01mm, while other manufacturers have 0.012. Bearings and spacers are customized
The X-axis screw has a specification of 5010 and the Z-axis has a specification of 8020, with stronger load-bearing capacity, rigidity, and durability Stronger accuracy retention.
Standard configuration includes Taiwan brand Intime, TBi, C3 level precision, while domestically produced products have P4 level precision, with a difference of one level
