subject: Automotive Manufacturing: Machine Tool Application Tool Case Study - Machine Tools - Machinery [print this page] In recent years, Great Wall cars Engine Works by world-renowned Machine tool Manufacturers high-speed, efficient processing center set up three production lines flexible machining, cutting tool manufacturers with world-renowned American Kennametal together carefully selected combination of processed products, cutting tools, is working to achieve fast and efficient cutting. (1) KSCM-AluMill surface Mills Cylinder block and head production line, we will Kenner KSCM-AluMill face milling cutter for milling aluminum alloy cylinder block and head surface. This cutter aluminum cutter knife by the steel body composition to ensure sufficient rigidity to reduce the weight of the premise, and the double-metal structure also reduces the processing of vibration. The tool has a high metal removal rate, low processing burr and high processing efficiency characteristics, is ideal for high-speed cutting. KSCM-AluMill face milling cutter blade 5 forms folders, each folder with a different knife for rough milling milling can be achieved by different surface roughness, we can also install the rough milling cutter folder fine, coarse finishing a complete, reduced processing time and improve efficiency.
We will use the actual processing of low-silicon aluminum alloy suitable for processing with high wear resistance, high life KD1415KD1420 two PCD cutting tool materials folder. KD1415 blade hardness, suitable for machining allowance uniform, consistent surface hardness, therefore, it is used for cylinder block, cylinder head and down around the surface finishing; KD1420 knife holder, blade toughness for margin uneven hardness inconsistent with the surface, be used in roughing. After finishing, cylinder block, cylinder head, on the following, before the other large flat surface behind the biggest error is not more than 0.02mm, the smallest to 0.0034mm, the average flatness error of less than 0.01mm, the surface roughness of less than Ra0.8 processing beats meet the requirements. KSCM-AluMill face milling cutter replacement blade folder, only the axial adjustment to do, no radial adjustment, with easy adjustment, adjustment of high precision short time to adjust the characteristics of the actual use of the Great Wall when the company realized the axial adjustment of deviation is less than 0.003 mm, so that uniform distribution of load to the cutting teeth on each blade, effectively extending tool life. After months of testing process, KSCM-AluMill face milling aluminum alloy good effect.
Name a cylinder top, bottom milling, for example, the top fine milling cutter 100, Z12 (9 folders is lean cutter, knife repair folder 3), revised the amount of light 0.008 +0.002 mm, the overall welding PCD blades ; processing parameters: V = 2500m/min, fz = 0.12mm / z, Vf = 11.5m/min; real test pieces after milling, surface roughness Ra0.8, flatness error
