The precision five-axis CNC machining screw main advantages
Ganyuan Hardware, relying on its five-axis CNC machining center and combining years of experience in precision screws machining, has summarized the following core advantages of five-axis CNC machining for custom screw

The precision five-axis CNC machining screw main advantages
The core feature of screws is their complex helical surfaces with varying diameters, pitches, and groove depths. Traditional machining methods require multiple clamping operations or specialized equipment. Five-axis CNC machining enables:
Completion of helical surfaces and end features in a single clamping operation: All features of the screw, including the helical groove, end face, bearing seat, keyway, and threaded hole, are completed in the same process.
Elimination of multiple clamping errors: Ensuring the coaxiality and phase angle relationship between the helical surface and the journals at both ends.
Adaptation to various complex screws:
Drive screws (trapezoidal thread, ball screw, sawtooth thread)
Extruder screws (single screw/twin screw, equidistant/variable pitch/gradual pitch type)
Injection molding machine screws (three-section: feeding section, compression section, metering section)
Compressor screws (female rotor/male rotor, helical profile)
Pump screws (single screw/triple screw, sealing profile)

II. High Precision and Transmission/Sealing Performance Advantages
The precision of the screw directly determines the transmission efficiency, sealing performance, and service life. Five-axis CNC machining can achieve:
Machining accuracy up to ±0.005mm
Helix lead accuracy ≤ 0.02mm/300mm, ensuring smooth and impact-free transmission
Gutter depth/width consistency ≤ ±0.01mm, ensuring uniform compression ratio
Surface roughness up to Ra 0.4μm (with grinding/polishing), reducing friction and material adhesion
Profile profile accuracy ≤ 0.01mm, ensuring uniform meshing clearance and reliable sealing for twin screw.
Equipped with professional testing equipment such as a coordinate measuring machine, helix measuring instrument, and profilometer.

III. Advantages of One-Shot Completion of screw End Features
The ends of screws often include features such as bearing seats, keyways, threads, and sealing grooves. Five-axis CNC machining can achieve:
Bearing Journal: Coaxiality with the helical surface ≤ 0.01mm, ensuring smooth rotation
Transmission keyway: Precise positioning, excellent keyway symmetry
Sealing groove/circlip groove: Groove bottom roughness Ra 1.6μm, reliable sealing
Internal thread/external thread: Thread accuracy 6H/6g grade, reliable fit
Internal hexagonal/torch drive hole: Completed in one clamping operation, ensuring phase relationship with the helix
