Chip breaking skill for turning.
In the turning of carbon steel and other plasticity metal materials, if not take chip removal measures, it is easy to form strip-like chips, continuous winding on the workpiece, tool and tool carrier, this chip can scratch the alresdy machined surface and the lathe bed and influences the machining, winding on the operating handle will effect operate, even hurt people, so we should take effective measures to avoid the emergence of strip chip, and make the chip be granulared or curled into a chip of a certain length.
The technique of selecting cutting fluid when turning stainless steel.
When turning stainless steel, it is the key to improve the surface quality of the parts to master the selection technique of cutting fluid. Most of the stainless steel materials are the stainless steel which containing titanium or nickel. The properties of the material are large toughness, strength and easy to be hardened when machining, makes its difficult to machining.

Factors affecting dimensional accuracy and improvement measures.
1. Measurement error. Because of the manufacturing errors of measuring tools, the error of measurement method leads to the fact that the measurement results can not reflect the actual size of the workpiece, and will directly affect the dimensional accuracy of the machined surface. Improve measures: according to the accuracy requirements, reasonable selection of measuring methods and measuring instruments; control measurement conditions, such as control measurement environmental temperature. 2. Adjustme
Problems and precautions in thread turning
1.Before turning the thread, check the spindle handle position and the position of the feed box handle. Turn the spindle by hand to see if the weight is too heavy or the Idle load is too large. 2.when using high speed steel cutting tools, lower cutting speed should be adopted, and pay attention to the intensity when turning. 3.When turning the thread, the clasp nut must be closed in place. If you feel that the gate is not closed, should immediately ra
Taper turning and taper measurement methods
The taper turning methods is usually: turn the direction of the feeding direction of the small slide, offset tailstock method, profile modeling method and the use of CNC turning lathe to machining taper surface. No matter what method is used to process the taper surface, the correctness of the taper by turning is the primary problem.

What is milling and the classification of milling
Milling refers to the use of a rotating multi-bladed tool for cutting workpieces. It is a high-efficiency processing methods, can be processed into any surface shape. When machining, the tool rotates (as the main movement), the workpiece moves (as feed motion), the workpiece can also be fixed, but at this point the rotating tool must also move (simultaneously complete the main movement and feed movement). 1. According to different cutting methods, milling is divided into three types: peripheral milli
What is work hardening, and what factors affect the machined surface hardening in cutting machining?
After machining, the hardness of the surface metal of the machined surface is often higher than the hardness of the base material, this phenomenon is called work hardening. In machining, the factors that influence the surface hardening are: 1. Tool. The larger the rake angle of the tool, the smaller the plastic def
Cutting Characteristics of Titanium Alloy
The melting point of titanium is high, the activation energy is large, and the lattice atoms are not easy to break away from their equilibrium positions. Therefore, when cutting machining, the energy consumed by cutting into the chip is larger. The more alloying elements are added, the higher the strength and hardness of the alloy, the harder the machining is. When the hardness of titanium alloy is greater than 350HB, the cutting is particularly difficult. And the hardness is less than 300HB will prone to sticky knife and difficult to cut. The best cutt
The basic way to improve the machinability of difficult cutting materials
There are many ways to improve the machinability of difficult to cut materials, but mainly from the cutting conditions. Under normal circumstances, the workpiece material can not be changed.

The selection of CNC processing methods and the determination of the processing plan
(1) Selection of processing methods The selection of the processing method is to ensure the processing accuracy and surface roughness of the processed surface. Because there are generally many processing methods to achieve the same level of accuracy and surface roughness, it is necessary to separate the shape, size, and heat treatment requirements of the parts when selecting in practice. For example, machining methods such as boring, reaming, and grinding for IT7-level precision holes can meet the accuracy requirements, but the holes on the box body generally use boring or reaming inste
