Tooling, How to choose the correct tool holder for the CNC Machining?

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

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
