Product Description

Product Introduction

This is a muti-station step shaft, which is made from 12L14 material by CNC machining process. It's used in the mechanical transmission system, it can serve as a transmission shaft to transfer power from one component to another. Meanwhile, the steps are utilized to install parts, playing roles in positioning and supporting.

Material and process

This muti-station shaft is made from 12L14 steel rod, which is a kind of a free-cutting structural steel, belonging to lead-sulfur composite free-cutting steel, which is often used in the manufacture of precision parts with high requirements for cutting performance. The core advantage of 12L14 steel lies in its excellent machinability. Through the combined effect of Pb and S, it can make material break more easily, reduce tool wear, and improve processing efficiency and surface finish. It is especially suitable for the production of precision parts such as multi-station shafts that require complex cutting processes. To confirm material quality, we have conducted inspections, and the following is the inspection report.

The shafts need to be made by automatic lathe machine. An automatic lathe is a type of metal-cutting machine tool with a high degree of automation. It can automatically complete multi-process machining of workpieces such as turning, drilling, boring, tapping, etc., through preset programs or mechanical structures like cams and levers, without the need for continuous manual operation.

It is suitable for processing small and slender parts, such as shafts, bolts, bushings, etc., and its production speed is much higher than that of ordinary lathes.
Most are equipped with automatic bar feeding mechanisms to achieve continuous and uninterrupted production, widely used in the efficient production of large quantities of standardized parts.

Packing

There is a layer of plastic film before put in carton to isolate the air and reduce oxidation. Finally laid the cartons on pallet and wrapped with protective film to avoid scattering.
