LancangKuning – Basic knowledge of machine tools This can be defined as a machine or equipment that can function to cut or transform a material into a finished or semi-finished product in a certain shape and size, even though the user who makes it.
The process of cutting and forming a machine also requires a tool or cutting tool which is often called a cutting tool or cutting chisel which can be used as a tool in doing all machine work.
The work process of this machine tool also has a mechanical system that varies depending on the function part or the type of machine tool used. The mechanical movement in question is a machine that can change the rotary motion into the same rotary motion or straight motion, the motion is accelerated or slowed down and is in accordance with the shape or smoothness of the surface to be made according to what it will use.
The surface quality in the cutting results depends on the cutting conditions (cutting condition) only between is cutting speed, feeding and cutting depth with what has been made by previous users. For example, for example a low cut speed in feeding and a fairly large depth of cut can produce a rough surface, this combination is also usually used for work and preliminary purposes (roughing) in doing it.
Basic Types and Classifications of Machine Tools
Machine tools can be grouped into 2 types, namely cutting machine tools and shape machine tools to be used by anyone who will use them. This type of cutting machine is a machine tool whose work process is used by removing part of the workpiece in order to obtain a certain shape.
Some basic examples of a machine tool that are often used both in the industrial world and in the world of education to be used in making machines, namely especially in technical vocational education, it will be easier for you to do whatever you are going to make, which are as follows.
Lathe (Lathe)
A lathe is a type of cutting machine that will run well with the working principle and the cutting process of the rotating part of the workpiece to be able to obtain a certain shape and size. The workpiece will rotate / rotate on its axis at a certain speed, then cutting or cutting will use a chisel to be moved in translation or parallel to the rotating axis of the workpiece.
Mesin Frais (Milling)
This milling machine is also a machine or tool that already has many functions including the function of leveling the surface, drilling, making grooves and making elbows. This type of milling machine consists of Horizontal, Vertical and Universal milling machines. And each type of machine still has a different type depending on how it is used.
Drilling Machine (drilling)
Drilling machine is one type of machine tool that will function to be able to make a hole and can also enlarge a hole that will be used. And the workpiece will be positioned quietly on the machine table, then the cutting tool will run using a drill bit mounted on a machine axis and will rotate according to the needs of its users.
Chainsaw Machine
This saw machine is a type of machine tool that can be used to cut a workpiece properly. The workpiece will be positioned at rest and across the saw blade for easier processing. The saw blade is also moved by swinging back and forth in such a way that there will be friction against the workpiece which results in a reduction in part of the workpiece until it breaks as determined in its manufacture.
