CK5123B CNC Single Column Vertical Lathe

Product description
CK51 series CNC single-column vertical lathe is a high-tech mechatronic product that our company has absorbed the most advanced contemporary design and manufacturing technology, adopted CAD optimization design methods, implemented enterprise precision standards, and equipped with domestic and foreign advanced functional components. Its structural performance has achieved powerful cutting, overweight load on the worktable, high dynamic and static rigidity of the machine tool, safe and reliable movements, long service life, and high processing efficiency.

CK5123B×13/8 is suitable for high-speed steel tools, carbide tools and various high-performance tools to process ferrous metals, non-ferrous metals and some non-metallic workpieces. It can complete rough and fine turning processes of inner and outer cylindrical surfaces, inner and outer cylindrical surfaces, planes, inner and outer ring grooves, etc.

Main structure
This machine consists of a bed, a worktable, a worktable base, a main transmission mechanism, a crossbeam, a vertical tool holder, an electric cabinet, a hydraulic system, a CNC system,Water cooling system,safety protection and other parts.

1. Workbench
The workbench consists of a rotary workbench, a workbench base, a spindle device and a transmission mechanism.
The base adopts a vibration absorption structure design, and uses radial and annular reinforcement ribs, with reasonable and optimized layout, so that the base has high strength, rigidity and shock resistance. The base rails are supported by hydraulic rails, and the spindle uses two sets of NN series tapered double-row cylindrical roller bearings for centering. The bearing clearance can be adjusted by pre-tightening the inner ring of the bearing to achieve a higher rotation accuracy. The spindle bearing is lubricated with a large flow of lubricating oil, which improves the accuracy and stability of the machine tool. The workbench is equipped with a spindle encoder to achieve constant speed cutting and thread processing.

2. Bed
The bed is made of high-strength, low-stress cast iron, which is treated by heat aging stress relief annealing and effective vibration reduction measures to make the bed have sufficient rigidity. The guide rail surface of the bed is finely ground, with good contact surface and high precision. The guide rail surface is supersonic quenched, and the quenching hardness is HRC48-55.

3. Beam
The beam lifting adopts a worm gear box and a T-type screw lifting mechanism. The beam moves along the column guide rail. There is a hydraulic locking mechanism on the beam. It is clamped by a hydraulic lever wedge block mechanism with a self-locking function, and interlocked with the beam movement to lock the beam firmly on the column. The beam lifting is equipped with mechanical limit and electrical soft limit double limit, which is safe and reliable.

4. Turning tool rest
The tool rest is controlled by a CNC system and consists of a beam slide, a rotary slide, a ram, a balancing cylinder and a ball screw assembly. The horizontal feed is driven by a servo motor through a precision planetary reducer to drive the ball screw to move horizontally. The vertical feed is driven by a servo motor through a precision planetary reducer to drive the ball screw to move vertically. The tool rest ram is equipped with a hydraulic balancing device to balance the weight of the ram and make the ram move smoothly.

5. Main transmission mechanism
The main transmission mechanism is driven by a 30KW servo motor to drive the gearbox. The gearbox is controlled by an electromagnetic slide valve to control the speed change cylinder, and the speed change fork pushes the speed change gear to achieve four-speed stepless speed change. The gear is made of 42 chromium-molybdenum high-altitude quenching treatment, with a hardness of HRC40-45 and a precision of 6. The gearbox has low noise, large torque transmission, no tooth breakage, and is reliable to use.

6. Operation part
The machine tool is equipped with a suspended main control console, on which are installed the operation panel and all the operation keys of the machine tool, spindle function, coordinate function, interpolation function, display function, compensation function, self-diagnosis function, hydraulic system of the workbench hydraulic guide rail and lubrication operation of each component, crossbeam lifting auxiliary function, etc. It can be programmed according to the processed parts, and can also realize manual operation function.

7. Hydraulic system
The hydraulic system includes: workbench hydraulic system, main transmission speed change system, crossbeam clamping system, and balance cylinder hydraulic system. The oil supply system of the workbench guide rail is composed of components such as gear pumps, and the oil outlets are connected to the oil chambers respectively. When processing workpieces of different weights, the output flow can be controlled by the flow selection switch to ensure the floating amount of the workbench.

8. Control system
The machine tool adopts Siemens 808D system, and this CNC control and mechanical action of the machine tool are interlocked at multiple locations to ensure the reliability and safety of the machine tool control and mechanical action. Once a fault occurs, just press the emergency stop button and the whole equipment will be powered off.

9. Electrical part
The electrical control part is completely independently designed, constructed, debugged and provided with after-sales service by our company (not outsourced), which effectively guarantees product quality and solves user worries.
The electrical design, manufacturing and installation of the machine tool comply with the International Electrotechnical Commission GB5226.1-2008/IEC60204-1:2005 and ISO13849-12006 General Technical Conditions for Electrical Equipment of Industrial Machinery Part 1.
