A micro grinder is a type of machining tool that is held in the hand like a pen to grind and polish workpieces. It is sometimes called a router or a reuter.
In addition to electric-powered micro grinders, there are also air-powered micro grinders.
The actual tool at the end of the machine is interchangeable, and the tool can be changed according to the processing content.
The rotation speed can be adjusted, and sufficient torque can be maintained for machining even in the low rotation range.
Micro grinders are used for deburring and chamfering of various metals, precision abrasive finishing and engraving, inside machining that is difficult for larger tools to penetrate, free-form surfaces, and other areas where fine machining is required.
They are also used for polishing and removing paint from brushes and other materials that cannot be rotated at high speeds.
They are also used for cutting and grinding plastics, ceramics, glass, stone, and wood.
Dentists use air micro grinders to grind teeth.
Micro grinders are mainly suitable for machining narrow areas such as deburring.
The micro grinder is a highly portable and compact machine that can be used for a wide range of applications. The direction of rotation can be selected from forward and reverse to suit the machining location.
The machine can be driven by either electric or air, depending on the infrastructure available. Air-driven machines can rotate at higher speeds than electric-driven machines. Rotation speeds are ~40,000 rpm for electric and ~10,000 rpm for air, and high-speed rotation can shorten processing time.
There are not only straight type grinders, but also angled types (45°~120°) that face downward.
Although rotary grinders are the most common, there are also back-and-forth and left-right motion types that go back and forth more than 100 times per second, allowing for corner machining, which rotary grinders are not good at.
