Various precision machining processes
Machining is a removal process that mainly uses cutting machines such as machining centers and lathes. The desired shape is created by cutting block material, round bar material, etc. using a machine.
Our company has long been involved in the production and supply of precision parts through machining.
Milling machine
This is a process in which a rotary tool such as an end mill or drill is rotated and pressed against the material to cut the material. It is mainly used to manufacture parts of precision machinery that require strength and precision. The machining accuracy is approximately ±0.1mm, but high-precision machining of approximately ±0.02mm is also possible.
Typical examples are aircraft body structural parts, but many parts such as brackets and housings are also milled. It is also used for secondary processing of cast products.
There are NC milling machines using numerical control, and machining centers equipped with automatic tool changing functions for NC milling machines. With the latest 5-axis machining machines, it is also possible to machine complex shapes with one set of materials.
General-purpose milling cutters are also used for secondary processing of castings. We can also handle general-purpose milling by experienced craftsmen.
Machining center
When cutting with a machining center, it is possible to create a variety of shapes by combining the blades and machining programs.
Plastic parts such as everyday electrical appliances and automobile panels were originally made by pouring resin into a mold called a mold. Creating this mold is also the main job of the machining center. It is also used for secondary machining of castings (machining the reference surface or drilling holes).
In addition, parts cut using machining centers are used as they are for precision parts in various fields such as aircraft structural parts, medical care, and semiconductors.
These parts are sometimes called "machined parts." From a simple square piece of material, the excess parts are removed with a knife to create the shape of the required part.
Lathe
This is a process in which a round bar is rotated and a cutting tool called a cutting tool is pressed against it to shave it. This type of machining is also called turning.
Although it is limited to concentric shapes, it is faster and produces a cleaner surface compared to milling. It is often used for processing parts such as shafts and collars.
Although there are many machines that only do turning, there are also machines such as compound lathes that also have milling functions, and automatic lathes that are equipped with bar feeders and are suitable for mass production.
Grinder
This is a process in which a rotating whetstone is pressed against the surface of the material to improve its surface roughness and refine the surface roughness.
Depending on the shape and location, surface grinders, cylindrical grinders, jig grinders, honing machines, etc. are used.
Wire-cut machine
This is a method of cutting the base material using a thin wire that is energized. Although machining time is required, a highly accurate machined surface can be obtained.
It has the advantage of being able to cut any material that conducts electricity, regardless of its hardness. Basically, it is used for machining straight cut surfaces.
Electric discharge machine (EDM)
This is a process in which an electrode (copper material or graphite) is created that has an inverted shape to the desired shape, and the material is removed by bringing the electrode close to the material while energizing it and causing an arc discharge.
Although it takes time to create the electrode, it is possible to transfer the shape with high precision, and it is also possible to process hard materials that cannot be cut with normal cutting. The advantage is that it can achieve R0.2).
It is often used for mold making, etc.
We also manufacture parts using various types of machining.
