Many front-line CNC machining workers will encounter some problems in their actual work. Based on years of experience in the CNC machining industry, 3QMACHINING has summarized three common faults and correct countermeasures in the CNC machining process for your reference. CNC machining handwheel failure The handwheel shaft selector switch is in poor contact. This problem needs to enter the system self-check to observe the specific conditions of the matching contacts of the axis selection switch (that is, the specific conditions of the connection line) and replace the switch if it is damaged. The handwheel multiple selector switch is in poor contact. The correct step to deal with the poor contact of the CNC machining handwheel multiple selector switch is to enter the system self-check to observe the specific conditions of the multiple switch matching contacts (ie the specific conditions of the connection line), and replace the switch if it is damaged. For the damage of the handwheel pulse disc, you need to remove the pulse disc

What is CNC Spindle The axis that drives the workpiece or tool to rotate on the CNC machine tool is called the machine tool spindle. The machine tool spindle is generally composed of bearings, spindles, transmission parts (gears or pulleys) and so on. In our actual applications, there are two types of high-speed spindles. One is a high-speed electric spindle with zero transmission. This type of spindle adopts an integrated structure of motor and machine tool spindle, and has precise dynamic balance correction. Therefore, it has good rotation accuracy and stability, but it also limits the output torque and power. CNC Spindle, How To Troubleshoot A Problem With The Spindle Of A CNC Machine Tool The other is a spindle that combines a variable frequency spindle motor and a mechanical speed change mechanism. The output power and torque of this type of spindle is much larger than other types, but its accuracy and stability are worse. Therefore, for this type of spindle, how to correctly design the machine tool spindle and its components? The machining accuracy of the machine tool has big impact. During production, we need to make sure CNC spindle is working well to produce good quality parts, but what problem the CNC spindle might have and how to fix it? How To Troubleshoot A Problem With The Spindle Of A CNC Machine Tool The spindle does not have a frequency converter, the spindle does not rotate: If it is suspected to be a mechanical transmission failure,
Slow wire cutting is a type of wire EDM, also called (WEDM-LS). It uses continuously moving fine metal wire (called electrode wire) as an electrode to perform pulse spark discharge to remove metal and cut the workpiece. It is mainly used to process all kinds of complex and precise small workpieces. How does WEDM-LS calculate the processing cost in factory production? Usually, the processing fee is calculated based on the processing area, so we will often hear how much it costs per square meter for slow-moving wire processing. This article has compiled a common processing fee calculation method for your reference. It must be noted that the prices of different processing conditions will vary, and cannot be generalized. How Much Of WEDM-LS? Basic processing calculation method: Basic processing refers to the general shape of the processed material of steel, the thickness of the workpiece is 20-80mm, and the brass wire of 0.2-0.25mm is used for processing. The price calculation method is: Total amount = cutting area * unit price + small hole price + punch (in block) price + fine hole discharge fee + material fee among them: Cutting area m㎡=(perimeter + lead) * thickness of workpiece Unit price of basic processing (yuan/m㎡): Cut a knife: $0.025/m㎡ One cut and one repair: $0.028/m㎡ Cut one and repair two: $0.033/m㎡ Cut one and repair three: $0.036/m㎡ The price of perforated wire hole: the diameter is greater than 0.30mm, the thickness is less than 30mm at 3 dollars per hole, the more
(Wire Electrical Discharge Machining is referred to as WEDM), which belongs to the category of electrical machining. When the former Soviet Union Lazarenko and his wife studied the phenomenon and causes of switch contacts damaged by spark discharge, they found that the instantaneous high temperature of electric sparks can melt local metals. , Oxidized and corroded away, thus pioneering and inventing the EDM method. The wire cutting machine was also invented in the former Soviet Union in 1960. Wire EDM machines can be divided into high-speed reciprocating wire EDM (Reciprocating type High Speed Wire cut Electrical Discharge Machining, commonly known as “fast wire”), and low-speed unidirectional wire EDM (Low Speed one-way walk Wire cut Electrical Discharge Machining, commonly known as “WEDM-LS“) and Vertical Wire Electrical Discharge Machining machine tool With Rotation Wire. Nowadays, the WEDM-LS is most common technique to machine custom parts due to most of parts require high quality surface and precise dimensions, it is the best cost effective and best quality option.

It uses continuously moving fine metal wire (called electrode wire) as an electrode to perform pulse spark discharge to remove metal and cut the workpiece. It is mainly used to process all kinds of complex and precise small workpieces. What is WEDM-LS use for? WEDM-LS (also called low-speed wire-moving wire-cut electric discharge machine tool) The electrode wire moves in a low-speed one-way, generally the wire speed is lower than 0.2mm/s,
CNC milling or manual milling is a machining process used to process prismatic parts 3QMACHINING is a top quality CNC machining manufacturer in DONGGUAN, GUANGDONG, CHINA. We are working our best work for your custom plastic & metal machining parts from design drawing or sample to final shipment with fast delivery and low MOQ. We are using advanced technology and equipment to offer high precision for producing metal and plastic machining parts. In this article, we focus on ultra-high-speed machining of titanium alloy. Machinability of titanium alloy Titanium alloy has the characteristics of small specific gravity, high thermal strength, good thermal stability and corrosion resistance, and is widely used in aviation, aerospace, atomic energy and chemical industries. However, the material is difficult to cut, and it has been continuously explored to solve the technical problems of low processing efficiency and poor surface quality of titanium alloys. As advanced manufacturing technology has become more and more widely used in manufacturing, the use of ultra-high-speed cutting technology to cut titanium alloys has shown obvious advantages. Factors that generally cause poor machinability of difficult-to-machine materials The material contains high hardness particles. High hardness or high hardness at high temperature. Large work hardening. Poor thermal conductivity and high cutting temperature. The material has high strength, especially high temperature strength. Easy to bond with tools. High chemical activity. The material to be processed may have poor machinability due to one or more of the above factors. Machinability analysis of titanium alloy It has a high chemical affinity. Titanium alloy isvery easy to “affinity” with tool materials at high temperatures
Precision CNC machining center machine tools combined with advanced cutting tools can provide excellent metal cutting productivity. As the key interface between the cutting tool and the machine tool spindle, the tool holder is essential for achieving high productivity. So, how to choose, apply and maintain the most suitable tool holder for production needs? Workpiece factors affect the choice of tool holder Factors that affect the selection of tool holders include the machinability of the workpiece material in each job and the configuration of the final part. These factors can determine the size of the tool holder required to reach a specific profile or feature. The handle should be as simple and easy to use as possible to minimize the possibility of operator error. The basic components of the machine tool play a key role-fast machine tools with linear guides will make full use of tool holders designed for high-speed applications, while machine tools with box grooves provide support for heavy-duty machining. Multi-task machine tools can complete turning and milling/drilling processes at the same time. Workpiece factors affect the choice of tool holder cnc machining The tool holder can also be selected according to the processing strategy. For example, in order to maximize productivity in high-speed cutting (HSC) processes or in high-performance cutting (HPC) applications, the shop will choose different tools. The former involves a shallower depth of cut HHS, and the latter focuses on sufficient power. However, machine tools with limited speed produce higher metal removal rates. Low repeatable
From a monthly salary of 2500 operators to a million-dollar CNC programmer master, it is only because he can summarize these experiences at all times!
After engaging in CNC machine tool processing for ten years, I have accumulated some machining skills and experience of CNC machine tools, mainly for CNC programming and parts processing. CNC Programming: Because most of our cnc machining parts have high requirements for the accuracy dimensions, the details that need to be considered when programming are: The processing sequence of the parts: Drill first and then flat end (this is to prevent shrinkage when drilling); Rough turning first, then fine turning (this is to ensure the accuracy of the parts); The first processing tolerance is large and the final processing tolerance is small (this is to ensure that the surface of the small tolerance size is not scratched and to prevent the deformation of the parts). Choose a reasonable speed, feed and depth of cut according to the hardness of the material: 1. The carbon steel material chooses high speed, high feed rate and large cutting depth. Such as: 1Gr11, select S1600, F0.2, and cut depth 2mm; 2. Low speed, low feed rate and small depth of cut are selected for cemented carbide. Such as: GH4033, select S800, F0.08, and cut depth 0.5mm; 3. Choose low speed, high feed rate and small cutting depth for titanium alloy. Such as: Ti6, select S400, F0.2, and cut depth 0.3mm. Take the processing of a certain part as an example: the material is K414, which is an extra-hard material. After many tests, the final selection is S360, F0.1, and the depth of cut 0.2 before processing qualified parts.
Titanium Alloy CNC Machining Technology Summary In recent years, the requirements for higher strength and lighter weight of automobile and aircraft parts have become higher and higher. Therefore, the proportion of CNC machining of these parts using titanium alloy materials is also increasing. Airframe components and jet engine compressor components are also increasingly using titanium alloys. In Boeing’s B787-8 jetliner, the amount of titanium alloy used per aircraft has increased to about 10 tons. This kind of titanium alloy material is generally called “difficult-to-cut material” with poor machinability. CNC machining cutting tools for processing such materials must also be able to adapt to the unique processing conditions and processing methods of difficult-to-cut materials. At present, the industrial method for the production of titanium metal is the Kraul method, and the product is titanium sponge. The traditional process of making titanium is to melt and cast sponge titanium into an ingot, and then process it into titanium material. Titanium adopts plastic processing, the size of adding soil is not limited, and it can be mass-produced, but the yield rate is low, and a large amount of scraps and residues are generated during the processing. In view of the above shortcomings of titanium plastic processing, powder metallurgy technology has been developed in recent years. The powder metallurgy process of titanium is the same as ordinary powder metallurgy, but the sintering must be carried out under vacuum. It is suitable for the production of large-volume, small-sized parts, and is especially suitable for the production of complex
