Processing Pneumatic drilling unit for composite materials such as CFRP

Technical Classification:
[ Processing ]
[ Equipment / Facilities ]
[ Air Driven ] [ CFRP ] [ composite materials ] [ Delamination prevention ] [ drilling ] [ Pneumatic ]

Point of the Proposed Technology

・Light-weight and compact portable drilling unit "Pneuconfeeder", utilizing Sugino Machine's drilling technology.
・Built-in high torque and high durable air motor.
・Stable drilling due to high precision spindle structure.


・Burrs and delamination reduced in drilling CFRP
・Weight reduction of the drilling unit

Conventional Technology

Example of application to CFRP

・With conventional portable drilling unit, spindle precision was not enough. Therefore, when drilling CFRP, there were problems like burrs and delamination, and also shortening of tool life. 
・With the structure of conventional portable drilling unit, it was not able to set drilling conditions suitable for different materials.
As a result, laminated workpieces with different types of materials took longer time with poor efficiency. 

New Technology

Example of application to CFRP

・With high precision spindle structure, high level run-out control is achieved. It can reduce burrs and delamination, and prolong tool life. 
・Pneuconfeeder is a complete air driven unit equipped with air motor for spindle rotation and air cylinder for feeding forward and backward. Air driven unit can process the work in accordance with work load, thus enables efficient drilling even in case of composite material laminated with different types of materials .
・With two-step feed speed ragulator equipped, it is possible to set pre-exit low feed which can reduce burrs and delamination.
