Çalışmanınamacı: Buçalışmada; zımparalanmış sarıçam ve doğu kayını odunlarında, kesiş yönü vezımpara çeşidinin yüzey kalitesine etkileri araştırılmıştır.Materyal veYöntem: Denemeleriçin mobilya sanayisinde en çok kullanılan sarıçam ve Doğu kayını odunlarıseçilmiştir. Örnekler 40, 60 ve 80 kum, 3 farklı zımpara ile zımparalanmıştır.İşlenen numunelerin yüzey düzgünlük ölçümleri TS 2495 EN 3274 ve TS 6956 EN ISO4287 esaslarına göre yapılmıştır. Yüzey düzgünlük ölçümlerinindeğerlendirilmesinde, iğne taramalı ölçme yapan Mitutoyo Surfest SJ-301 cihazıkullanılmıştır. Denemeler için 36 adet test numunesi kullanılmış ve her örnek 8eşit parçaya bölünerek bu bölümlerden liflere dik yönde ve 20 mm boyunda ikiölçme yapılmıştır. Sonuçlar: Deney sonuçlarına göre en düzgünyüzey; sarıçam odununda, teğet yüzeyde, 80 numaralı zımpara ile elde edilmiştir.En pürüzlü yüzey ise; doğu kayını odununda, teğet yüzeyde, 40 numaralı zımparaile elde edilmiştir.AraştırmaVurguları: Özellikle ahşap mobilyaimalatında; ağaç malzemeler daire testerelerle biçildikten sonra, rendelemeişlemi yapılmadan 60 ve 80 kum zımparalarla zımparalanarak düzgün yüzeyler eldeedilebilir. Bu durum üreticilere ekonomik fayda sağlayacaktır.

Aim of the study: In this study; effects of the gritsize of abrasive and cutting direction on surface quality of sanded Scotchpine and Oriental beech woods were investigated.Material and Methods; Scotch pine and Oriental beech whichare commonly used in furniture sector were chosen. Specimens were sanded withthree different grit sizes of abrasives; namely, 40, 60, and 80-grit. Thesurface roughness of specimens was measured using Mitutoyo Surfest SJ-301stylus scanner device on the basis of TS 2495 EN 3274 and TS 6956 EN ISO 4287.In total, 36 test samples were used for the experiments and each specimen wasdivided into eight equal parts and two measurements were made perpendicular tograin at 20 mm length.Main results: Thesmoothest surface was obtained from the Scotch pine when sanded at tangentialsection with 80-grit abrasives. The roughest surface was obtained from theOriental beech when sanded at tangential section with 40-grit abrasives. Highlights: Especially,in the production of wooden furniture; after the wood materials are cut withcircular saws, smooth surfaces can be obtained by sanding them with a 60 and80-grit abrasives without planing. This will provide economic benefits toproducers.
