About This Product

■What is SEH Gravostar?

Gravostar marking tool (micro percussion tool) Gravostar marking tools can be used inside machine tools (CNC machines). Therefore, there is no need for a special engraving machine and it is possible to reduce the number of workers. Also, compared to writing with a ball end mill, etc., the marking speed is faster and the tool life is significantly longer.

■Summary

・Air drive type ・Coolant drive type ・Scratching type (marking) ・Roller emboss type There is a lineup of the above four engraving methods.

■Air drive type

Unlike engraving with a ball end mill, etc., the Gravostar air drive type performs marking by applying point pressure by vibrating a carbide stylus at high speed. Since the air-driven type operates with a constant vibration of 300Hz, the distance between the dots is extremely short, making it possible to achieve beautiful marking quality with high visibility. The mechanism for controlling the vibration of the stylus is integrated into the tool. This means that when the machine's air supply is turned on, the stylus starts vibrating. The oscillating stylus of the Gravostar H-20 tool works using compressed air supplied through the machine spindle. All mechanisms necessary for tool operation are integrated into the tool.

■Application field

Marking on workpieces We have a track record of use in a variety of fields such as automotive parts, pneumatic/hydraulic parts, etc.

■General information
