How to make a marine transmission shaft using a CNC lathe machine?

CNC lathe machines play a vital role in many industries, providing solid technical support for the rapid development of industry. They are indispensable key equipment in modern industrial production, which can automatically complete the machining process in accordance with pre-set procedures, greatly reducing manual intervention and improving production efficiency and consistency.

In the marine industry, CNC lathe machines can manufacture engine parts, such as crankshafts and connecting rods, to ensure the performance and reliability of the engine. It can turn and mill these complex shaped parts with extremely high precision, ensuring a tight fit between them. For the ship’s transmission system, CNC lathe machines can accurately process key components such as transmission shafts and gears.

Take the transmission shaft as an example, the next engineer from Shanghai ANTISHI Machinery Equipment Co., Ltd. will explain to you the use of CK6150 CNC flat bed lathe for its processing of marine transmission shaft:

1.Preparation:

Selection of high-strength materials suitable for ship’s drive shafts with diameters smaller than the bar through diameter Φ80/Φ128.

Select the appropriate tool, such as cylindrical turning tool, grooving tool, thread turning tool and so on.

Install and calibrate the fixture to ensure that the drive shaft can be firmly clamped and accurately positioned.

Mount the rough drive shaft to be machined on the fixture. 2.

2.Rough turning:

CK6150 flat bed CNC lathe machine set the appropriate cutting parameters, such as rotational speed, feed rate and so on.

Use the external turning tool to roughly turn the drive shaft to remove most of the excess material and approach the final size.

3.Fine turning:

Adjustment of CNC lathe machine cutting parameters for finer external turning to achieve high precision dimensions and surface roughness requirements.

4.Machining Features:

Use grooving cutter to machine keyway or other annular grooves according to design requirements.

Use thread turning tool to process the threaded part.

5.Inspection and Correction:

Perform periodic dimensional inspections during machining to ensure compliance with tolerances.

If necessary, carry out micro-corrective machining.

6.Surface Finishing:

Surface treatments such as polishing are performed as needed to further improve surface quality.

For example, when rough turning the outer circle on a CNC lathe machine, the material may be removed quickly at a relatively high feed rate and rotational speed first, and then the rotational speed and feed rate are reduced to improve the surface finish when finishing; when machining the keyway, the depth, width and position of the groove should be accurately controlled, and other parameters should be accurately controlled. The whole machining process needs to be carried out in strict accordance with the process requirements and operating procedures to ensure the machining of high-quality marine drive shafts.

If you are also a manufacturer in the marine industry, or have similar processing needs, through the drawings or workpieces you provide, we will recommend the CNC lathe that best meets your processing needs. We believe that our rich experience in manufacturing and utilizing CNC machine tools can provide you with professional technical support.
