Metal surface treatment, ten methods, see how many you know?

Surface treatment is to form a surface layer with one or more particular properties on the material’s surface by physical or chemical methods. Surface treatment can improve product appearance, texture, function, and other aspects of performance. 1. Anodizing It is mainly the anodic oxidati... Read More

Selection and Maintenance of Machine Tool Chucks in the Machining of Engine Shaft Parts

For engines, shaft components such as crankshafts, camshafts, and cylinder liners use chucks in each processing process. During processing, the chucks center, clamp and drive the workpiece. According to the ability of the chuck to hold the workpiece and maintain the center, it is divided into rig... Read More

Machining center programming skills, sharing from CNC technicians!

We usually have three options for drilling cycle selection: 1. G73 (Chip breaking cycle) Usually used for machining holes more than 3 times the diameter of the bit but not more than the effective edge length of the bit 2. G81 (shallow hole circulation) It is usually used for drilling center holes... Read More

How to choose the appropriate drilling cycle?

We usually have three options for drilling cycle selection: 1. G73 (Chip breaking cycle) Usually used for machining holes more than 3 times the diameter of the bit, but not more than the effective edge length of the bit 2.

What is the difference between chrome plating, nickel plating and zinc plating?

First, let’s understand what is electroplating.Electroplating uses the principle of electrolysis to coat a thin layer of other metals or alloys on the surface of certain metals. Such as rust), improve wear resistance, electrical conductivity, reflectivity, corrosion resistance (copper sulf... Read More

A small tap can contain so much information. . .

Tap chipping Tapping is a relatively tricky machining process because its cutting edge is basically in 100% contact with the workpiece, so various problems that may arise should be considered in advance, such as the performance of the workpiece, the selection of tools and machine tools, and the ...

Another “lighthouse factory” in China! ! !

In 2021, the World Economic Forum (WEF) officially released a new list of “lighthouse factories” in the global manufacturing sector. Sany Heavy Industry’s Beijing pile machine factory was successfully selected, becoming the first certified “lighthouse factory” in the... Read More

Precautions when the machine tool is shut down for a long time

Good maintenance can keep the machining accuracy of the machine tool in the best state, prolong the service life, and adopt the correct startup and debugging method for the CNC machine tool. In the face of new challenges, it can show a good working state and improve production efficiency and proc... Read More

We are welcoming the Chinese Spring Festival!

We are welcoming the Chinese Spring Festival! The Spring Festival has a long history and evolved from the prayers for the first year of the year in ancient times. All things originate from the sky, and humans originate from their ancestors. To pray for the new year to offer sacrifices, to respect... Read More

Why is titanium alloy a difficult material to machine?

  1. Physical phenomena of titanium machining The cutting force of titanium alloy processing is slightly higher than that of steel with the same hardness. Still, the physical phenomenon of processing titanium alloy is much more complicated than that of processing steel, which makes titanium allo... Read More

Nine major errors in machining, how many do you know?

Machining error refers to the degree of deviation between the part’s actual geometric parameters (geometric size, geometric shape, and mutual position) after machining and the ideal geometric parameters. The degree of agreement between the actual and ideal geometric parameters after the pa... Read More

Characteristics of CNC Hard track

Most factories understand hard rails and linear rails: if they are used to make products, they buy linear rails; if they are processing molds, they buy hard rails. The accuracy of the linear rails is higher than that of the hard rails, but the hard rails are more durable. Hard track characteristi... Read More
