CNC machining breaks free from the fixed specifications of standard calibrated screws, allowing for full customization based on individual needs such as equipment installation space, thread specifications, length, groove type, and material. Whether it's fine/coarse threads, extra-long/extra-short specifications, special drive grooves like hexagonal/slotted/torch, or special head structures such as set screws, tapered ends, flat ends, and spherical ends, all can be precisely machined as needed, perfectly adapting to special assembly scenarios such as automated equipment, tooling fixtures, precision instruments, and robot parts, solving installation problems where standard parts cannot be matched.
Thread machining is the core performance indicator of calibrated screws. CNC machining, relying on a precision lathe system, can precisely control the thread profile, pitch, and pitch diameter tolerances, ensuring 100% pass rate for thread gauges and eliminating problems such as stripped threads, misaligned threads, and excessively loose/tight fits. Meanwhile, the perpendicularity, coaxiality, and parallelism of the grommets' end faces can be precisely controlled, effectively ensuring the fit between the screw and the workpiece. After tightening, there is no shaking or offset, providing stable and reliable support for equipment positioning, anti-loosening, and fixation, suitable for long-term use under high-frequency vibration and heavy-load conditions.
Customized solutions for precision CNC machining machine screws
CNC machining is adaptable to various commonly used industrial materials, providing customized material solutions for different application scenarios. For example, carbon steel/alloy steel grommets can achieve high-strength, high-hardness tightening; stainless steel has excellent rust and corrosion resistance, suitable for humid environments; copper grommets combine conductivity and anti-loosening properties, suitable for electronic equipment; titanium alloys meet the needs of lightweight, high-strength high-end equipment. During machining, cutting parameters can be optimized according to material characteristics to avoid thread chipping, deformation, and burrs, ensuring the machining quality and performance of grommets made of different materials.
The CNC-machined granulator screw substrate has a smooth, burr-free surface, making it directly compatible with various subsequent surface treatment processes. Surface treatments can be applied as needed to improve the screw's rust resistance, corrosion resistance, and wear resistance; polishing and mirror finishing can also reduce surface roughness and assembly resistance.
Non-standard customization of granulator screws is mostly done in single-piece or small-batch production. Traditional stamping and cold heading processes rely on molds, resulting in high costs and long lead times for small-batch customization. CNC machining eliminates the need for molds, allowing for direct production based on programming. This enables rapid response to needs such as sample making, small-batch production, and old part replication. Furthermore, CNC machining can complete multiple processes such as turning, tapping, forming, and chamfering in a single setup, reducing clamping errors and significantly improving processing efficiency.
