Product Description
High precision Hot Sale Crankshaft Connecting Rod Neck CNC Lathe
Product Description
This series CNC crankpin lathes are specially designed for turning crankpin. They are suitable for precision turning of crankpin of motor cycles, automobiles, diesel engine sets, heavy trucks and large marine crankshafts. They replace the rough grinding process with high-speed and high-precision turning.
Product Features
1. High-precision machining
Advanced CNC system: usually equipped with well-known CNC systems such as Siemens, Fanuc, Guangshu or Kandi, with high control accuracy, can accurately implement various complex machining instructions, ensure the accuracy and stability of machining, and can make the precision of fine turning external cylindrical machining reach IT6.
Precision transmission components: such as ball screw transmission, which has the advantages of high transmission accuracy, low friction, and no gap, can accurately convert the rotational motion of the motor into the linear motion of the tool or workbench, ensuring the position accuracy during the machining process.
2. High-efficiency performance
Multi-tool machining capability: Some lathes are equipped with front and rear tool holders, which can process the connecting rod neck and the side of the crank arm at the same time, reducing the machining time and improving production efficiency.
Fast feed rate: The X-axis and Z-axis have a high fast feed rate. For example, the X-axis and Z-axis fast feed rates of CKY4240 can reach 20000mm/min, which can quickly position the tool and workpiece and shorten the non-cutting time.
High stability and rigidity
High-quality bed structure: It adopts high-strength cast iron materials, such as HT300 castings, which have good vibration absorption and wear resistance, can withstand large cutting force and impact force, and ensure that the machine tool maintains stable accuracy during long-term processing.
Reasonable layout design: The various components of the machine tool are reasonably laid out, with a stable center of gravity, which reduces vibration and deformation during processing, improves processing quality and reliability of the machine tool.
3. High degree of automation
Hydraulic auxiliary system: Equipped with hydraulic chuck, hydraulic turret, hydraulic tailstock, etc., the hydraulic system realizes automatic clamping, tool change and tailstock telescopic operations, reduces manual intervention, and improves production efficiency and processing accuracy.
Automatic centralized lubrication and cooling system: The automatic centralized lubrication system can provide lubricating oil to each lubrication point of the machine tool in a timely and quantitative manner, reducing friction and wear, and extending the service life of the machine tool. The cooling system can effectively reduce the temperature of the tool and workpiece during processing, ensuring processing quality and tool life.
4. Strong processing adaptability
Special chuck design: The special chuck has the collet of the general chuck and the function of adjusting the eccentricity and azimuth angle. It can adapt to the characteristics of the crankshaft connecting rod neck and the crankshaft rotation line not coinciding and the different azimuth angles of the crankshaft neck, which is convenient for clamping and processing crankshafts of different specifications.
Various accessories can be configured: According to different processing requirements, accessories such as power turret, power tool, tool setting instrument can be configured, which expands the processing function of the machine tool and can complete more types of processing tasks.
