Technical parameters of ck6150s CNC lathe

Description and characteristics of machine tool structure

1. High rigid inclined integral bed

1) The machine tool adopts 45 ° rear integral inclined bed, which is cast by precision resin sand. The internal rib is box type and cylinder structure. The layout is reasonable, the guide rail surface is wide, and the overall rigidity of the bed is high. Users can obtain higher machining accuracy, improve the speed of rapid movement and obtain higher production efficiency.

The machine tool Z axis adopts rectangular sliding guide rail pair, after medium frequency quenching, the hardness of guide rail surface ≥ hrc52, precision grinding, good durability and high rigidity. The base surface of the bed guide rail, the head box guide rail surface, the tailstock guide rail surface and the z-axis screw bearing seat installation surface constitute the important machining surface of the bed. In the design process of this part, the overall shape of the machine tool, ventilation and heat dissipation, collection of cooling water leakage, chip conveyor installation, machine tool lifting and other aspects are considered. X axis is line guideway structure.

2) High speed, high rigidity and high precision spindle

This series of machine tools are single spindle headstock. The spindle bearing of this kind of spindle box adopts china famous brand precision spindle bearing and is lubricated with German fag high-speed lithium grease. The spindle box adopts symmetrical structure to make the thermal deformation uniform and avoid the deviation of the spindle center. In order to reduce the thermal deformation of the machine tool, heat dissipation measures are added. For example, the heat generated by the high-speed operation of the spindle can be fully and rapidly diffused to the outside by adopting the structure of heat sink with expanded distribution outside the box. In the design of headstock, measures are taken to improve the accuracy and rigidity of the spindle. The motor is used to drive the spindle to rotate directly after changing speed through the belt pulley, which reduces the power loss of mechanical transmission and starts quickly and stably.

The machine tool is equipped with china domestic 8 "medium solid hydraulic chuck to ensure that the holding force of parts is not deformed, the clamping positioning accuracy of parts is high, and the machining dimension consistency is high.

3) Feed system

The servo motor is directly connected with the ball screw through the coupling for longitudinal and transverse feed. The ball screw is fixed at one end and supported at the other end. This support mode can make one end of the screw freely extend, thus avoiding the longitudinal bending caused by the increase of temperature in the working process. In order to compensate for the elongation of the lead screw caused by the rise of working temperature, ensure the positioning accuracy of the lead screw and the system rigidity of the ball screw, pre stretch and pre tighten the lead screw according to a certain amount of thermal elongation before assembly, so as to eliminate the influence of temperature rise on the accuracy.

4) tailstock

This machine is equipped hydraulic tailstock, down part structure of tailstock is automatic hydraulic lock, which is realized by two sets hydraulic cylinder, tailstock Hydraulic jacking.  The movement of tailstock is realized by carriage hanging and moving, workpiece is hydraulic against.

5) turret and carriage system

The carriage and slide plate are one of the important parts of the machine tool. They are cast with resin sand and treated by artificial aging. The position of the screw nut seat is scientific and reasonable. It should be considered together with the internal protection in the design. The base surface of each guide rail is an important machining surface.

The machine tool is equipped with 8-Position horizontal hydraulic servo turret and appropriate accessories, which has strong process adaptability. The tool holder has high reliability and the accuracy of repeated positioning is as high as ± 1.5 ″. When the turret is rotated, the path can be optimized and the nearest tool can be selected. The time for each station to rotate is 0.2 seconds.  

This machine is a high degree of automation CNC machine tools, equipped with hydraulic chuck, hydraulic tailstock, hydraulic or servo turret, etc. Variable vane pump is selected for hydraulic system, and Taiwan products are used for hydraulic control components. The hydraulic oil tank is placed behind the bed and isolated from the outside by protection. The control valves of the hydraulic circuit are respectively placed in the relevant positions of the machine tool. Each hydraulic circuit adopts the Superposition valve installation mode, which is compact in structure and convenient in installation. The pressure of each oil cylinder of the hydraulic system can be adjusted separately, and there is a pressure protection device.

The hydraulic system adopts air-cooled cooling device to ensure the continuous operation of the machine tool.

6) Cooling and lubrication

The retractable stainless steel protective cover for z-axis adopts inclined back design, which makes it easy to remove chips and collect coolant. In addition, the cooling device adopts multi-layer filtration to fully purify the coolant and avoid blocking of the cooling circuit. The cooling box and chip conveyor are integrated with the main machine to make the heat balance distribution of the machine tool more ideal. The adopted cooling pump has a flow rate of 20 L / min, a lift of 20 m and a cooling tank capacity of 60 L. The machining accuracy and tool life of the tool are improved in the machining process.

User cooling chip removal mode: chip conveyor type right chip; The whole machine adopts centralized automatic lubrication system.

7) Electrical system

Electrical system design of machine tools Gb-5226.1 electrical standard. The power circuit of the circuit has over-current and short-circuit protection, and the relevant actions of the machine tool are interlocked to ensure the safety of equipment and personnel.

The electrical system has the function of self diagnosis, and the operation and maintenance personnel can observe the operation status of each part of the machine tool at any time according to the indicator light and display.

The standard configuration of the electrical cabinet is fully enclosed and equipped with heat dissipation and air outlet, so as to achieve the purpose of dust prevention and cooling. The protection grade of electrical cabinet meets the requirements of IP54, and a certain space is reserved in the electrical cabinet to facilitate the expansion of functions.

8) protection

The machine tool adopts fully enclosed protection, and the stainless steel guide rail inner protective cover is convenient for chip removal. The whole machine protective cover has beautiful appearance and good amenity. At the same time, a number of safety protection measures are considered, such as the safety device of the electric control cabinet, the safety operation door, and the reinforced glass design of the operation door, so as to ensure the safety of machinery and people.

9) Safety protection

The machine tool has alarm device and emergency stop button, which can prevent all kinds of sudden failures from damaging the machine tool. Due to the reasonable design of the software, the alarm can display text and alarm number through the display and the indicator light on the operation panel. The machine tool divides the alarm processing methods into three categories according to the situation: implement "emergency stop" for emergency alarm, "feed hold" for general alarm, and only "prompt" for operation error.
