Deep-hole drilling is widely used in hydraulic components, molds, injection systems, shaft parts, tooling, and precision machinery. According to structural layout, deep-hole drilling machines are mainly divided into horizontal type and inverted vertical type.
The machine structure significantly affects machining range, chip evacuation, stability, and accuracy.

The Fixed Guide Bush, also known as the steady rest or follow rest, is an auxiliary support device installed on the bed guide rail. It plays a role in preventing vibration, bending and jumping in the processing of slender workpieces. It is especially indispensable when processing long shafts or slender parts.

Macro Program or User Macro in CNC system is a powerful function that allows users to use programming structures such as variables, arithmetic and logical operations, conditional branches (IF...THEN...ELSE), loops (WHILE...DO...END) to write more flexible, more general and parameterizable machining programs.

A reamer is a finishing tool used for hole processing. It is mainly used to precisely trim the inner holes that have been pre-drilled, bored or punched to improve the hole's dimensional accuracy, geometric shape accuracy (such as roundness, cylindricity) and surface finish. It is one of the core tools for high-precision hole processing in mechanical manufacturing.

In the application of CNC lathes, the spindle speed variation (SSV) function effectively breaks the resonance frequency during the processing, reduces chattering, and improves processing stability by introducing small periodic fluctuations around the spindle speed. Based on the set speed, the system makes the spindle speed fluctuate periodically within a small range instead of maintaining a constant speed.

G72 is a rough turning cycle command in CNC lathes, mainly used to automatically complete rough machining of external circles or end faces. Different from programming by cut, G72 can generate multiple tool paths at one time by setting cutting areas and parameters, realizing intelligent machining of "automatic layering and automatic feed".

 5C and 16C are two classic American standard collet system models, designed by Hardinge Inc. in the United States and widely used in various precision turning equipment worldwide. They are precision fixtures used to hold cylindrical workpieces, relying on elastic deformation to generate clamping force, featuring high accuracy, stable clamping, and suitability for high-speed machining.

In CNC milling, vibration may occur due to the limitations of cutting tools, tool holders, machine tools, workpieces or fixtures, which will have a certain adverse effect on machining accuracy, surface quality and machining efficiency. To reduce cutting vibration, relevant factors need to be considered. The following is a comprehensive summary for your reference .

Both systems support ISO standard G-codes such as G01, G02, G03, etc. The basic programming logic is similar.

In modern manufacturing, CNC lathes have become indispensable processing equipment. As the "teeth" of CNC lathes, tools play a crucial role in determining machining efficiency and product quality. This article will help you understand the classification and characteristics of CNC lathe tools, enabling you to select the most suitable tools for your production needs.

As the most commonly used cutting tool in the machining process, the drill bit's geometry directly affects the drilling efficiency, hole diameter accuracy, surface roughness, and the durability and life of the drill bit. In the drill bit geometry design, the top angle, helix angle, core thickness, chisel edge shape, edge modification, and surface coating are key parameters.

Countersinking is a metal processing method that refers to processing cylindrical countersunk holes, conical countersunk holes, and boss end faces on processed holes.

Cutting speed is the relative linear speed between the cutting edge and the workpiece. At every point, the cutting speed is the product of the drill's rotational speed (spindle speed) and the circumference. At the center of the drill, the cutting speed is always zero, and it gradually increases as you move away from the center. Therefore, in drilling, the term "cutting speed" refers to the maximum cutting speed occurring at the drill's outer diameter. On the surface of the drill, the cutting speed varies according to the distance from the center.

Unlike through holes, blind holes do not pass through the workpiece. They have a bottom, which is why blind holes are often referred to as guide holes. The bottom of the hole is also a potential issue for blind hole threads, which does not occur with through holes. If not handled properly, chips can accumulate in the blind hole. Additionally, the tap may collide with the bottom of the blind hole and break, or other problems may arise. Those who frequently use taps with blind holes often encounter these issues. The primary solution to this problem is to avoid misalignment and prevent the blind hole thread from becoming larger than intended.

Soft jaws are versatile and can be machined to fit specific workpieces, ensuring precise gripping and reducing the risk of damage, making them ideal for delicate or unique tasks. Hard jaws, on the other hand, are pre-hardened, durable, and suitable for repetitive or high-torque operations, providing strong and consistent clamping. Soft jaws excel in flexibility and customization, while hard jaws prioritize longevity and efficiency for standard applications. Both are essential depending on the machining requirements.

During metal processing with CNC lathes, a large amount of cutting fluid is used, leading to the formation of numerous oil mist particles in the air. Metalworking lubricants are complex mixtures that, in addition to hydrocarbons, often contain sulfonates, fatty amines, nitrates, dyes, biocides, and other chemicals. If the lubricant has been in use for some time, due to the oxidation of hydrocarbons, microbial growth, or contamination by external impurities, it may contain additional chemicals that are harmful to both humans and the environment. Therefore, controlling the concentration of oil mist in metalworking workshops is a crucial measure for ensuring occupational safety and health in production enterprises.

CNC machining relies on precise parameter settings to ensure accuracy and repeatability. The proper setting of machining parameters determines the quality and efficiency of the machining process. These settings include spindle speed, feed rate, depth of cut and cutting tool path.
