The CNC positioning system allows operators to set cutting length and remnant length, helping reduce length deviation and maintain consistent results during repeated cutting.
The machine uses a dedicated carbide-tipped metal saw blade for high-speed cutting. It produces smooth and clean cut surfaces while reducing burrs, deformation and secondary grinding.
The high-speed spindle works with a suitable feeding process to improve cutting speed and productivity. Compared with traditional band saws and abrasive cutting machines, it is better suited for batch cutting applications with demanding production cycles.
The machine uses a servo motor, high-precision ball screw and guide rail feeding system to ensure smooth material transfer, reduce feeding deviation and improve cutting positioning stability.
Cutting length, remnant length and other processing parameters can be entered through the touch screen. The PLC system automatically controls the cutting process, making operation intuitive and product changeover convenient.
The saw blade uses dedicated metal-cutting tips combined with precision grinding technology and an optimized tooth-angle design to maintain stable cutting performance and good surface finish.
To address the challenges of slow cutting speeds and poor verticality in processing high-hardness alloy steel drive shaft blanks for a leading oil drilling and heavy machinery component supplier in Russia—which resulted in excessive machining allowances and high costs—Baorui Machinery deployed its fully automatic high-speed CNC circular saw solution; featuring an innovative zero-clearance gearbox and TCT carbide saw blade technology, the system enables high-speed, stable cutting for solid metal bars. This solution ensures sawing length precision remains stable around ±0.05mm with a mirror-like surface finish, significantly reducing subsequent machining time and helping the client cut unit labor costs by approximately 50% while dramatically boosting the production turnover of core heavy equipment parts under demanding industrial conditions.
