PVA 海綿彈性精密研磨砂輪 PVA Grinding Wheels The PVA grinding wheels are elastic grinding wheels bonded with Polyvinyl Alcohol and are much characterized by the sponge structure. The PVA grinding wheels have proved themselves to be the best elastic grinding wheels for polish-grinding jobs in production work, saving operation cost by automation of grinding operations and contributing to upgrade of product quality. PVA磨輪是由聚乙烯醇所結合而成的彈性磨輪，并以海綿狀的結構為其特徵。由於可以經由自動化大幅度節省作業成本，以及提昇產品品質，因此PVA磨輪已被證實為在拋光研磨制程中的彈性磨輪。 Characteristic of PVA grinding wheels 1、an even and excellent finished surface can be obtained with elasticity-effect of the PVA bond which makes the depth of cut of abrasive grains uniform and prevent deep scratches on surface 2、unique and regulated pores permit a long time continuous grinding operation. Reducing generation of grinding heat with less loading 3、The PVA grinding wheels , having good conformability to curved surfaces , provide much more excellent finished surface than other of abrasives such as abrasive papers or iron buffs. 1、以PVA為黏著材質，這樣的彈性效果，可以讓磨粒所造成的切削深度一致，并經此達成出色的精致表面及平坦度，同時也可以避免表面產生太深的刮痕。 2、獨特且規則的氣孔允許長時間持續性的研磨加工，同時因為較少的堵塞，也減低研磨熱能的產生。 3、PVA對於彎曲的表面，擁有良好的一致性，也因此相較於砂紙或鐵制拋光輪等其它研磨材，PVA磨輪可以研磨出極出色的精致表面。 用途 Applications 1、most effective for use on softer hard-to-grind materials in which polish-grinding jobs grinding heat and loading are easily generated. Works stainless steel, aluminum, copper, brass, titanium, other alloyed steels, wood, glass, stones, and plastics. 2、Designed particularly for obtaining an excellent finishing (up to mirror finishing ), reducing finishing time and eliminating processes. Proved the best elastic grinding wheels in automation and mechanization of conventional hand and buffing jobs. 1、當應用在較軟，研磨過程中很容易產生熱能及堵塞不易研磨的材質上時，PVA磨輪是有效果的。例如，不銹鋼、鋁、銅、黃銅、鈦、合金鋼、木材、玻璃、石材以及塑膠制品 2、是為了達到佳的拋光程度(可到達鏡面拋光)，同時也可以減少精密加工的時間以及減少工序，所特別設計。 對於機械化及自動化而言，是適合的彈性磨輪。 Watch case and band表殼及表帶 Stainless steel pipe不銹鋼管 Kitchen knife and scissors刀具及剪刀 Motor cycle rim to remove welded part磨除摩拖車輪圈中焊接部位 Removing paint defect of car body去除車體油漆缺陷部位 Titanium drum for PCB copper foil PCB銅箔用鈦鼓 Stainless steel sink 不銹鋼水槽 Titanium rolls 鈦金屬滾筒、滾輪 Glass and marble stones 玻璃及大理石 Various jewelry(gold/silver/platinum) 珠寶(金/銀/白金)Various metal molds.各式金屬模具
