outer diameter machining

The profile machining is a method of contacting the cutting tool from the outside of the rotating material. It is the most used processing method in Lathe processing, and is used to beautify the finishing of the surface and to roughly cut the target shape in the initial stage of processing.

Outside diameter machining, the resulting chips may be entangled in the cutting tool. When particularly high-precision finishing is required, it is necessary to adjust the angle of the cutting tool in order to prevent the chip from being entangled and the precision from being deteriorated.

 Inner diameter machining

In the inner diameter machining, the inside of the material is cut, thereby enlarging the hole made in the material by the hole machining. Used to adjust the size of the hole and beautify the inner surface.

For inner diameter machining, it is necessary to lengthen the tool according to the depth of the hole to be machined. However, a long tool is prone to offset, so attention must be paid to the decrease in accuracy. In addition, since the chips collect in the hole, the chips need to be removed frequently.

Thread cutting

Thread cutting is a 1 processing method to produce pitch. In lathe processing, both external and internal threads can be processed with special thread cutting tools. In the case of milling and machining centers, usually only internal threads can be manufactured, so the ability to manufacture external threads is a major advantage of lathe processing.

The special tool for thread cutting is in contact with the material to make the tool move at a constant speed. In order to equalize the pitch, the "automatic feed function" is often used to keep the speed constant.

 Hole machining

Hole machining is a method of making holes by placing a drill bit against a rotating material. When machining the inner diameter, it is necessary to punch in advance to allow special tools to enter. At this time, the hole is used for machining.

The accuracy of drilling with a drill is not too high, so it is generally used for finishing after opening a hole of the required size.

 Cutting

Cutting is a machining method in which an unnecessary part is cut off by abutting a cutter against a material. It's like cutting a cylinder into discs.

It is necessary to use a tool with a thin blade, and it is necessary to work while checking vibration and sound, so a certain skill is required. In order to carry out high-precision machining, some measures need to be taken, such as the use of flexible blades, the use of oil when cutting, etc.
