Depth interpretation shank type Shank models are what does it mean? BT40, BT50 mean? Machine factory shop today Xiaobian you know about the mysterious shank models. You first need to understand is that the handle of the model must keep supporting the machine spindle, and depending on the spindle shank can be divided into universal shank taper 7:24 and 1:10 of the HSK. Universal shank which is positioned by 7:24 7:24 cone contact with the spindle taper shank hole connection, HSK shank is by 1:10 vacuum cone and spindle taper hole 1:10 contact. 7:24 Universal shank shank which is common to those common market, such as BT series, SK series, CAT series handle, these models also represent different manufacturing standards, as follows:? BT said the Japanese standard MAS403 Manufacturing shank, JT said that the adoption of international standards ISO7388 manufacturing, ST said that the use of Chinese GB3837 manufacturing, SK on behalf of the German standard DIN 69871, CAT by the United States on behalf of the ANSI standard. Which BT40, BT50, said shank size of the code, the former representative of the large end of the taper diameter of 44.45, which is 69.85. Having a common shank, then talk about the HSK. HSK shank vacuum with German standard DIN69873, there are six kinds of standards and specifications, which are A, B, C, D, E, F series, there are three commonly used: HSK-A (with internal cooling ATC), HSK-C (with manual tool change in the cold) and HSK-E (cold-band ATC, high speed type). To choose the right holders, users need to know their machine of choice is what taper accordingly select the appropriate series and the appropriate model, so as to avoid incompatibilities. Do you know the number of specifications CNC tool holders it? Supporting concerned with matching tool shank tool and CNC tool holders, especially in the selection of brand ER tapping shank tool holders, pay attention to tap the drive is equipped with a square head size. Furthermore shank ER quote on CNC machine tools use a single edge boring tool retraction to avoid scratches when the workpiece, but should pay attention to the direction of the tip relative to the shank keyway: Some tools require consistent and keyway orientation, while The machine requires a vertical position with the keyway. The number of specifications NC shank monolithic TSG tool system includes 20 kinds shank shank ER sales, the number of up to hundreds of specifications, the user can select the shank of different specifications according to the CNC machining process typical parts can meet the processing requirements and not cause accumulation. CNC CNC tool shank specifications 7:24 taper shank most used tool shank, and using the appropriate type of rivet taut structure and spindle fit.
