Features an integral box-type HT300 bed, 550 mm wide guideways, and hardened, precision-ground guideways. The large-diameter spindle with heavy-duty three-point bearing support enables both heavy cutting and fine machining.
The X and Z axes use precision-ground ball screws. Each machine is dynamically tested and compensated using a RENISHAW laser system before delivery. Spindle runout is 0.010 mm, machining accuracy reaches IT6–IT7, and surface roughness can achieve Ra 1.6 μm.
Suitable for shafts, sleeves, discs, and other complex parts. It can perform internal and external turning, taper turning, arc turning, facing, grooving, chamfering, and threading. Ideal for high-mix, small- and medium-batch production.
Equipped with an 11 kW servo spindle motor. Four-step mechanical speed changing, stepless speed control within each range, and constant surface speed cutting are supported. The 100 mm spindle bore is suitable for larger bar stock and heavy workpieces.
The electric tool turret provides fast and convenient tool changes. Programming and operation are simple, reducing dependence on highly skilled operators. Rapid traverse speed reaches up to 6 m/min.
The headstock uses forced circulation lubrication, while guideways and ball screws use centralized automatic lubrication, helping reduce heat, wear, and maintenance requirements.
Available with GSK, FANUC, or Siemens 828D CNC systems. Depending on the selected system, it supports network communication, remote monitoring, and integration with gantry loaders and robotic systems.
Optional 6- or 8-station turrets, hydraulic/pneumatic chucks, hydraulic tailstocks, steady rests, follow rests, chip conveyors, 15 kW motors, and full enclosure are available to suit different applications.
Customers can select optional equipment based on workpiece clamping method, production efficiency requirements, and automation level:
Standard delivery includes the main machine, lighting unit, coolant unit, automatic lubrication unit, V-belts, foundation bolts, nuts, washers, leveling blocks, 3-jaw chuck, center, and common tools. Technical documents include packing list, certificate of conformity, operation manual, electrical manual, electric tool post manual, and CNC system manual.
Choose CK6142 if your main workpieces are medium or small-diameter shafts, sleeves, and disc parts, and the φ58mm spindle bore meets your bar passing requirements. It is also a practical choice when machine footprint and budget need to be controlled.
Choose CK6152 if you need a larger swing over bed, larger swing over the tool post, or a φ80mm spindle bore for larger bars and workpieces. It is better suited to customers machining larger-diameter parts.
Select the distance between centers according to the maximum workpiece length, clamping method, center support requirement, and tool clearance. If the workpiece length is close to the machine limit, reserve additional allowance and confirm whether steady rest, follow rest, or a special tailstock is required.
For small-batch and general-purpose machining, the standard configuration covers most applications. For higher clamping efficiency, consider hydraulic chuck, foot pedal switch, and chip conveyor. For long shafts or slender shafts, confirm steady rest, follow rest, and tailstock configuration carefully.
To recommend the right model and configuration, customers are advised to provide:
It is suitable for shaft, sleeve, and disc-type rotational parts. It can process external and internal cylindrical surfaces, tapered surfaces, arcs, end faces, grooves, chamfers, and threads.
CK6152 has a larger swing over bed, larger swing over tool post, and larger spindle bore. It is better for larger-diameter workpieces or larger bar passing requirements. CK6142 is more suitable for medium and small workpieces and general-purpose machining.
Yes. The standard configuration includes a GSK980TD AC servo CNC system. The specification also mentions optional FANUC, SIEMENS, or other CNC systems, which should be confirmed when ordering.
Yes. Hydraulic chuck, pneumatic chuck, electric chuck, and other chuck options are available as special configurations for customers who need higher clamping efficiency or automation.
The series offers several distances between centers from 500mm to 3000mm, with optional steady rest, follow rest, and tailstock configurations. For long or slender shaft machining, the workpiece length, diameter, weight, and support method should be confirmed before ordering.
Manufacturing and acceptance are based on GB/T 25659.1-2010 and GB/T 25659.2-2010. The specification lists spindle centering runout of ≤0.010mm, machining dimensional accuracy of IT6-IT7, and surface roughness of Ra1.6.
