Flat Bed CNC Lathe, CAK63/80 Series
CAK 63/80 series CNC lathes integrate proven structure, stable functionality, and reliable quality to make an economical, practical, universal machine. They are widely used in such industries as automotive, petroleum, military, among others. They are the preferred lathe among customers in China.
This series of machine tools can be used in a wide range of applications, and can machine inside or outside surfaces of shaft-type work-pieces and disc-type workpieces, curved surfaces, arcs, threads, bores, and reaming holes, among other things. Various CNC systems and accessories can be provided according to the needs of the customer.
This series of CNC lathes have horizontal flat-vee hardened guide-ways, with the undersides of slides coated with TSF anti-friction material, for flexible operation and stable and reliable accuracy.
Key parts of the lathes are all hardened, and are designed to provide good rigidity to the cutting operation.
The main motor is the variable-frequency (inverter) type, and this is combined with automatic hydraulic range change which allows any range of speed to be programmed.
The tool turret is of the Hirth-style coupling type, which means that positioning of the tool-post in a rotary axis is accurate and repeatable.
The feed system uses ball-screws with high accuracy drives and directly-coupled motors to eliminate error due to backlash of screws, gears or belts.
The flat bed CNC lathe integrates mechanical, hydraulic, and electrical/control systems in a sleek, compact design.
Because of its modular design, many different configurations can be selected by the end-user. Internationally-recognized control systems can be selected by the customer, such as FANUC, SIEMENS, SMTCL-NC-100, etc.
Available tool-post configurations include vertical 4-station, vertical 6-station, and horizontal 6-station.
Guarding is available either for semi-enclosed or fully-enclosed configurations. Manual or hydraulic chucks, and manual or hydraulic tail-stock options are available.
Maximum turning diameter of parts is 630 mm. (CAK 63 series) or 800 mm. (CAK 80 series). Each series has a full complement of standard and available accessories and equipment.
For machines whose maximum machining length is 1350 mm. or less, no steady or follower rests are provided. For machines whose maximum machining length is 2850 mm. or greater, roller-style rests are provided.
Flat Bed CNC Lathe, CAK100Q Series
This series of flat bed CNC lathe is mainly used to turn various shaft-like workpieces, disc-shaped workpieces, threads of many types and pitches, arc surfaces, conic surfaces, and internal or external curved surfaces of rotary-type parts. The CNC lathe can turn parts of ferrous, non-ferrous, or other materials, even at high speed if necessary. It is well suited to turn rotary parts with high accuracy, high efficiency, and in large batches, and it is widely used in such industries as automotive and motorcycle, electrical-electronic, aerospace, military, etc. The machining accuracy of the lathe can be up to Grade IT7, and surface finish up to Ra 1.6 um.
This CNC lathe adopts a multi-speed spindle, with high accuracy pre-loaded spindle bearings, improving its accuracy. It is designed to minimize heat in the headstock, thus reducing thermal distortion, contributing to greater accuracy.
It was designed for maximum reliability: ball screws in both axes have locking nuts; the saddle is lined with anti-friction material and has adjustable gibs to ensure greater machining accuracy.
The automatic lubrication system of our flat bed CNC lathe is metered according to travels, thus ensuring adequate and reliable lubrication to the ways and other moving parts, while not wasting lubrication oil through over-application.
The CNC lathe has full workspace enclosure for safety considerations as well as for containment of coolant. Special attention was given in the design of our CNC lathes to ensure labyrinth-style lapping joints between the doors, between the Z-axis ball-screw cover and the headstock guard plate, between the rear guard and the headstock guard plate, between the door and the headstock guard, and other places to ensure little or no leakage of coolant from the workspace.
The electrical panel is designed with modern design tools, and is very well sealed, very well laid-out, and reliable in its function.
The flat bed CNC lathe has an integrated coolant system to remove heat from the machining process, keeping both the tools and the workpiece from distorting, thus ensuring accuracy and improving the service life of the tools.
