Medical stent laser cutting machine description

Medical precision stent laser cutting machine is referred to as medical stent laser cutting machine or small stent laser cutting machine. The cutting machine is mainly composed of a precision motion table, a controller, a laser, a precision rotating shaft, a precision laser cutting head, a dual-drive laser micromachining system, an industrial computer, and a numerical control system. The equipment has a highly flexible system process capability, which can meet the needs of precision thin-walled pipe small slits, dry and wet cutting, length and special-shaped pipes, centripetal/vertical/double-station processing, online measurement and error compensation, automatic feed processing, splicing Material and other diverse system processing technology requirements.
