氟涂层刀具铣削饰面刨花板的切削性能
|
摘要
分析氟涂层刀具铣削饰面刨花板的切削性能,为氟涂层刀具在木材切削加工领域应用提供理论指导。利用CNC加工中心分别进行未涂层刀具和氟涂层刀具铣削饰面刨花板试验,采用工具显微镜和扫描电镜拍摄刀具前后刀面的磨损形貌,采用超景深三维显微镜对饰面刨花板的切削加工表面进行粗糙度测量,研究氟涂层刀具铣削饰面刨花板的切削性能。结果表明,在相同的铣削长度条件下,氟涂层刀具铣削饰面刨花板的后刀面磨损带宽度显著低于未涂层刀具的后刀面磨损带宽度,且随着铣削长度的逐渐增加,未涂层刀具磨损带宽度增加急剧,而涂层刀具磨损带宽度增大缓慢;氟涂层刀具主要为磨料磨损,可以有效减少胶黏剂和刨花颗粒产生的黏结磨损,且降低崩刃现象;在相同的铣削长度条件下,氟涂层刀具铣削饰面刨花板的切削表面粗糙度值明显低于未涂层刀具铣削饰面刨花板的切削表面粗糙度值,且铣削饰面刨花板的刨花层可显著减少表面毛刺和凹坑,且饰面耐磨层崩边较少。因此,氟涂层刀具铣削饰面刨花板可以有效降低刀具磨损,提高饰面刨花板切削表面质量。
The milling performance of the cutting tools with fluorinated surfactants-based coatings against decorative particleboard was analyzed to provide theoretical guidance for the application of fluorinated surfactants-based coatings in wood cutting processing.The CNC machining center was used for the milling test of decorative particleboard with uncoated tools and fluorine coated tools.The wear morphology of the tool face was measured and analyzed by tool microscope and scanning electron microscope.The roughness of the machined surface of decorative particleboards was measured by a super depth of field three-dimensional microscope.The cutting performance of the fluorine coated tool during decorative particleboards was studied.It was showed that under the same milling length,the flank wear band width of the fluorine coated tool during the milling of decorative particleboard was significantly lower than the uncoated tool.As the milling length increased,the uncoated tool wear band width increased sharply,while the coated tool wear band width increased slowly.The wear mechanism of fluorine-coated tools was mainly abrasive wear,which could effectively reduce the abrasive wear caused by the adhesive and the particle,and reduce the chipping of cutting edge.Under the same milling length,the cutting surface roughness of the fluorine coated tool during the milling of decorative particleboards was significantly lower than the uncoated tool.The burrs and pits of wood-particles layer and the chipping of wear-resistant layer decreased during the milling of decorative particleboards with fluorine-coated tools.Thus,fluorine coated tool could effectively reduce tool wear and improve the cutting quality during the milling of decorative particleboards.
