Polishing is a surface machining technique to produce a high-quality finished surface on the product. It is a multistage process, in which each subsequent stage uses a finer abrasive. This paper aims to design and fabricate a polishing machine that performs polishing stages continuously, eliminating the idle time in the polishing process. The designed machine consists of four spindle heads, each of which carries a unique flap wheel. The flap wheels can raise or lower according to the size of the workpiece to be polished. Three types of rollers were adopted in the machine: a mild steel roller coated with heat resistant rubber, a hylam roller and a nylon roller. A pneumatic clamping system was placed at the feeder to fix and hold the workpiece. In addition, the compressor pressure is regulated by a pressure regulator. A prototype of the polishing machine was fabricated according to the design, and used to polish several types of workpieces. The results show that this machine can polish stainless-steel flat bars, square tubes and rectangular tubes into 10mm-150mm width products, operate at a high speed of 2,000~3,000 rpm, and, most importantly, execute multiple polishing operations continuously. The proposed polishing machine is helpful to the automation of the polishing industry.

ÖzTeknolojinin sürekli değişip gelişmesiyle birlikte, birçok alanda yeni makine ve cihazlar insanlığın kullanımına sunulmaktadır. Bu çalışmada, metalografik incelemeler yapmak için, numune hazırlama aşamalarından biri olan ve tam otomatik olarak çalışacak bir numune zımparalama ve parlatma makinesinin tasarımı ve imalatı yapılmıştır. Bu amaçla, daha önceden imal edilmiş numune zımparalama ve parlatma makineleri incelenerek, bu makinelerde görülen eksiklik ve aksaklıklar dikkate alınarak, yeni bir tasarım gerçekleştirilmiştir. Yapılan tasarımda, makinenin otomatik olarak beş farklı istasyonda numuneyi zımpara üzerinde tutan basınç değeri ve zımparalama süresi ayarlanabilmektedir. Beş farklı istasyonda ve her istasyonda arzu edilen tane büyüklüğünde farklı zımparalar yerleştirilmek suretiyle istenilen kalitede numune yüzeyi elde edilecektir.
