Firstly, Cutting the amount of turning parts 1. Cutting speed VC Cutting speed has a complicated influence on surface roughness. Generally, there will be no debris tumor when cutting at low speed or at high speed, so the surface roughness value after processing is small. Higher cutting speed can also greatly improve productivity. For example, YT15 is used to cut 35 steel, and the critical cutting speed is v > 100m/min. 2. The surface roughness value will be reduced by appropriately reducing the feed amount f. 3. Generally speaking, the effect of cutting depth ap on the roughness of the machined surface is not obvious. However, when ap < 0.02~0.03mm, due to the influence of machining radius, extrusion, skidding and periodic cutting of the machined surface often occur, thus increasing the surface roughness. In order to reduce the surface roughness, the cutting depth should be selected according to the sharpness of cutting edge grinding. Secondly, Machining tool parameters for turni

A  stainless steel part  is a part that is processed by a lathe on a lathe. The shape and size of the blank are changed by the rotary motion of the workpiece and the linear motion or curved motion of the cutter, and it is processed to meet the requirements of the drawings.  Custom stainless steel parts  machining is a method of machining a workpiece on a lathe by turning it relative to the tool. The cutting power of turning can be provided primarily by the workpiece rather than the cutter. Turning is the most basic and common machining method, which plays a very important role in the production. Turning is suitable for machining rotary surfaces. Most workpieces with rotary surfaces can be machined by turning, such as inner and outer cylindrical surfaces, inner and outer conical surfaces, end faces, grooves, threads and rotary forming surfaces. The tools used are mainly turning tools. The precision of turning to the machine is generally IT11-IT7, and some can reach IT6, and the surface

CNC lathe technology is currently the most widely used. We have talked about that some products which are difficult to be processed by general machine tools need to adopt CNC lathe technology. So what are the main processing objects and contents of this technology? Although CNC lathes are similar in structure and processing technology to ordinary lathes,  CNC turning parts  in  China  are controlled by electronic computer digital signals through pre-programmed machining programs, so there are many differences. It has many requirements, high machining precision, automatic shifting, and linear and arc interpolation. The ordinary lathe cannot meet these conditions, and the processing range is not wide. Therefore, compared with the ordinary lathe, the main processing contents of  CNC turning parts  are turning outer circle, turning inner hole, turning end face and turning thread. The main processing objects are also the following. 1. Parts with high precision requirements. The accu

The society is constantly advancing. Today's lathe processing technology is spread all over the transportation, industrial and general machinery industries, and it is developing rapidly and comprehensively. Gradually, consumer demand for intelligent and automated machine tools is increasing, especially for turning precision and process changes. Everyone's high requirements for machine tools are a good thing for our turning parts processing center. They can promote our learning and new technologies and apply them to the actual situation, that is, to promote their own development and meet the needs of customers. As a  CNC turning manufacturer , although Shengtang is constantly introducing new technologies, we need to learn a positive and innovative attitude. So what is efficient cutting technology? Efficient cutting technology is mainly a concept of machine tools, tools, and cutting fluids, and is an integrated processing technology. High-efficiency cutting is a systematic

CNC technology is a technology that uses digital information to control mechanical motion and work processes. The application of CNC technology not only brought revolutionary changes to the traditional manufacturing industry but also made the manufacturing industry a symbol of industrialization. ​ CNC machine tool is a high, precision, pointed technology in one, set machine, electricity, light, the liquid in one of the high-tech products. It has many advantages such as high processing precision, stable and reliable processing quality, high production efficiency, strong adaptability and good flexibility. It becomes popular in various industries and is receiving more and more attention in terms of use. To use the CNC lathe for turning parts, first of all, a step-by-step determination plan should be made, that is, the preparation work before the operation is clearly defined. The principle of positioning benchmark selection 1) The principle of benchmark coincidence. In order to avoid the r

High efficiency and high precision machining are one of the most important features of CNC machine tools. The positioning and clamping of the workpiece within the fixture are particularly important during the processing of the product. The product must be reasonably positioned according to the six-point positioning. Under-positioning, full positioning or over-positioning must be determined according to the actual production process. The fixture is a clamping device that covers almost all operations from machining to assembly. Since a large number of machining operations require clamping, the fixture design becomes very important in the manufacturing system, which directly affects the quality of processing, productivity and manufacturing cost. Turned parts   must follow the six-point positioning criteria: Full positioning — all six degrees of freedom are limited. Incomplete positioning (partial positioning) — Six degrees of freedom are not (and not necessarily) all limited. Unde

Before processing the  machining parts , we should draw a drawing, which marks the processing requirements of the machining parts, but it can not guarantee that every part of the processing can reach the standard, so it will be accepted after the test. So, do you know what the acceptance of  machining parts  includes?  Specifically, this includes acceptance requirements and acceptance procedures: 1. Acceptance requirements (1) Appearance check A: Check whether the finish of machining parts meets the requirements of drawings. B: Check whether the surface of the machining parts is damaged, rusty, bruised, and whether the thread shape and angle are correct. C: If the above problems are found, detailed records should be kept for reference. (2) Quantity acceptance A: Based on the supply contract and processing voucher, the material, specifications, and quantity of the processed parts should be checked strictly against the drawings and should be checked one by one. B: Do a good job in quanti
