The Importance Of Effective Cutting Speed Since the table feed depends on the speed at a certain cutting speed, if the effective speed is not calculated, the table feed will be calculated incorrectly. If the tool’s nominal diameter value (Dc) is used in calculating the cutting speed, the effective or actual cutting speed is much…
Milling Cutter Positioning The cutting length is affected by the position of the milling cutter. Tool life is often related to the length of cutting that the cutting edge must bear. The milling cutter positioned in the center of the workpiece has a short cutting length. If the milling cutter is offset from the center…
Use Of Down Milling And Up Milling The main recommendation is to use as much milling as possible. When the cutting edge is just cutting, the chip thickness can reach its maximum value in the down-cut milling. In the case of up-cut milling, it is the minimum value. In general, tool life in up-cut milling…
What Is The Most Important Factor In The Cutting Process? One of the most important goals in the cutting process is to create an evenly distributed machining allowance for each tool in each process. This means that tools of different diameters (from large to small) must be used, especially in roughing and semi-finishing operations. The…
What Is The Most Important And Decisive Factor In Choosing Mold Steel? The cutting process should be divided into at least 3 process types: Roughing, semi-finishing and finishing, and sometimes even super finishing (mostly high-speed cutting applications). The residual milling is prepared for finishing after the semi-finishing process. It is important to work hard in…
What Are The Important Application Parameters For Hardened Die Steel Milling? When finishing high-speed milling of hardened die steel, one of the main factors to be observed is shallow cutting. The depth of cut should not exceed 0.2/0.2mm (ap/ae: axial depth of cut / radial depth of cut). This is to avoid excessive bending of…
What Is The Most Important And Decisive Factor In Choosing Mold Steel? 1. Forming method. Choose from two basic material types. (1) Hot working tool steel that can withstand relatively high temperatures during die casting, forging and extrusion. (2) Cold-worked tool steel for blanking and shearing, cold forming, cold extrusion, cold forging and powder press…
What Is The Primary Factor Affecting The Machinability Of Materials? First of all, the chemical composition of steel is very important. The higher the alloy composition of steel, the harder it is to process. As the carbon content increases, the metal cutting performance decreases. Second, the structure of the steel is also very important for…
Main Test Procedure For Injection Molding Machine In order to avoid unnecessary waste of time and trouble during mass production, it is necessary to patience to adjust and control various processing conditions, find the best temperature and pressure conditions, and develop standard test procedures, and can be used to establish daily work methods. 1. Check…
What Data Is Required To Be Recorded During The Injection Molding Machine? Record and analyze the data as a need to modify the mold and production conditions, and as a reference for future mass production. 1. Make the processing run time longer to stabilize the melt temperature and hydraulic oil temperature. 2. According to…
