Our Activity Areas

Lathe;
Turning the part to remove chips by giving a rotating motion in front of the cutting tool, and the benches that perform these operations are called lathe. Lathe is one of the oldest and most important machine tool tools. The use of machine tools as a means of production started with human history. The first lathe was conceived by turning a tool tied between two trees. This was called a wood lathe. The first convenient lathe made by keeping the trees for many years was developed in France in 1700. During the industrial revolution, a British named Henry Moudslay developed the first lathe to pull a screw. After that, most of the first lathes in the United States had both wood and metal parts. The first lathe made of metal materials was developed in 1850. Although the working principles of all developed lathes are the same, today much more modern lathes have been developed. It is the oldest and the most used lathe among the benches developed until today. There are many types of lathes.



Leveling;
Most of the items used in daily life are made in the leveling workshop. Many products are manufactured thanks to the molds and machines produced in the leveling workshops. The finisher transforms the metal workpiece from the raw state to a state that it can perform its task in the machine. Leveling workshops are the place where the last process is done to machine parts.



Casting;
Casting is the process of pouring molten metals into molds prepared in the desired way. When the liquid metal poured into the mold solidifies, casting takes the shape of the mold. Most of the metal materials go through the casting process in the production processes. Most of the common molds are made of other materials such as sand, clay, ceramic, mortar, metal. These items are wrapped on the surface of the shape made of wood or something else to determine the form into which the molten metals will be poured. When the shape reaches a level that can preserve the properties of the mold, it is separated from the mold. Molds usually consist of two parts. After removing the shape, the two shapes are combined. With pinning and compression, the two shapes are combined exactly. Then the molten metal is poured into the mold through special entrances. It is ensured that the molten metal is distributed in all directions of the mold. The mold must be strong enough to withstand the stresses of molten metal. In addition, the molten metal must penetrate the mold sufficiently to expel other gases in the mold cavity. Otherwise, there will be holes in the casting. In addition, the metal from which the mold is made should not combine with the metal poured into the mold. Shapes made for the foundry require attention and skill. In order to compensate for shrinkage that will occur during temperature drops and liquid to solid state change, the shapes are made wider than the desired casting. The polystyrene foam inside the mold evaporates when it encounters the molten metal. Beeswax must be melted before casting the molten metal into the mold. Metal molds are used for metal casting types. Generally, it is desirable to have a hollow space inside the casting. For this, the scrapped fine sand is put into one of the mold pieces.
