Slow wire walking, also called low-speed wire walking, is a kind of CNC machining machine tool that uses continuously moving fine metal wire as an electrode to pulse spark discharge on the workpiece to generate a high temperature of over 6000 degrees, ablate metal and cut into a workpiece. The principle of wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge. Since the slow-moving wire cutting machine adopts the method of wire electrode continuous feeding, that is, the wire electrode is processed during the movement, so even if the wire electrode is worn out, it can be continuously supplemented, so it can improve the machining accuracy of the parts and slow the wire. The surface roughness of the workpiece processed by the cutting machine can usually reach Ra=0.8μm and above, and the roundness error, linear error and dimensional error of the slow-moving wire cutting machine are much better t
How Do Cnc Swiss Machines Work Save 0 What Is Swiss Machine –The full name of the walking CNC lathe, it can also be called the spindle box mobile CNC automatic lathe, the economical turning and milling compound machine tool or the slitting lathe. It belongs to precision machining equipment, which can complete compound machining such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch machining of precision hardware and special-shaped shafts. This machine tool first originated in Germany and Switzerland. In the early stage, it was mainly used for precision machining of military equipment. With the continuous development and expansion of industrialization, due to the urgent needs of the market, it was gradually applied to the machining of civilian products; the development of similar machine tools in Japan and South Korea Earlier than China, it was mainly used in the military industry in the early days. After the war, it was gradually
Spring Design Attention And Roll Forming Method The coiling characteristics and methods of springs are divided into cold coiling method and hot coiling method. Cold winding method: When the diameter of the spring wire is less than 8mm, the cold winding method is adopted. High-quality carbon spring steel wire is usually first cold drawn and then heat treated. After winding, it is generally not quenched, but only tempered at low temperature to eliminate the internal stress during winding. Hot-rolling method: Springs with larger diameter (>8mm) spring wire should use hot-rolling method. Hot rolled springs must be quenched and tempered at medium temperature. The Design Process Of Various Springs · Installation space: When designing a compression spring , it is necessary to have a clear understanding of the space required for the installation of the spring, in order to effectively grasp the basic manufacturing conditions of the compression spring, including the outer diam
In various industrial fields, five-axis linkage Cnc Machining centers are tools that have been widely used in recent years. Especially when researching and developing five-axis machining of products, due to the development of new products, metropolises need special-shaped, new or complex parts, so its utilization rate is even higher. But precisely because of the extremely high complexity of five-axis machining of research and development products, the probability of tool collision is high. How can we avoid knife collision as much as possible?
Adding optional module programming Op to the simulation solution can effectively allow users to improve the NC program according to the motion mode of each machine tool, and use efficient lateral motion to automatically find a better orientation without collision for multi-axis machining.
It allows programmers to avoid errors to a great extent when manually optimizing the axis position. The overall improvement process is complicated, so the following three points should be given priority when implementing.
1. Consider the properties of specific machine tools
Table of Contents
When programming for various types of machining centers, a very obvious advantage of Op will appear. Its simulation software can be adjusted according to the operating conditions of the CNC machining machine tool to control and implement comprehensive collision detection, so it can be relatively independent of the machine tool. Attribute creation CAM program, thereby improving the flexibility of process allocation and processing.
2. Op detection limits
Op can also find other problems that may arise. For example, if the machine axis rotation is limited, the software will take this into consideration when selecting tool positions and ensure smooth machining. If there is an axis limit, Op will interrupt the tool path, slowly retract the tool and retract the axis to avoid this limit. Then the tool will slowly feed again and continue machining. This method can be used for spiral machining on restricted machine tools. Angle head machine tools can also be used with Op to achieve dynamic machining.
3. Use as many axes as needed
The software optimizes the feed motion and automatically determines whether positioning with the rotary axis is faster. The rotation axis moves along a short path, and the movement of the linear axis is greatly reduced. In this way, a faster speed can be achieved during exercise. If a 3-axis movement is not possible due to a collision or axis restriction detected, Op will change the movement with the help of four or five axes. For various types of operations, whether it is 2.5-axis, 3-axis or 5-axis, they can be effectively connected, thereby reducing the timeliness of auxiliary processing. When the tool is close to the workpiece, the collision will be checked first to ensure that the tool will not retract to a safe plane during movement, effectively shortening the processing time.
Although five-axis milling is a challenging CNC lathe processing mode in the research and development of five-axis machining, due to programming and improper operation by employees, it is easy to hit the tool and affect the qualified rate of processed products, but the matter is human, through Op programming The improvement can effectively consider the axis limitation and optimization algorithm processing sequence at the same time, thereby reducing repositioning, improving efficiency, and ensuring the safety of processing.
