Our extensive manufacturing processes and experienced capabilities can meet your production needs, helping to simplify your supply chain and enable “one-stop” ordering for your entire project.
SCZY LTD provides one-stop surface treatment services such as sandblasting, anodizing, and electroplating for horizontal milling machined parts, covering more than 10 types of processes to meet the needs of multiple industries. Through professional testing, we provide data reports on film thickness, hardness, salt spray testing, etc., to ensure the protective performance and appearance quality of the treatment layer, ensuring that the parts are durable and aesthetically pleasing.
SCZY LTD utilizes horizontal milling technology to process metals such as aluminum alloy, brass, and titanium alloy, as well as engineering plastics like ABS and POM. With four-axis interpolation, we achieve processing accuracy of ±0.01mm and surface roughness of Ra≤0.8μm. We maintain quality control throughout the entire process from prototyping to mass production, providing high-precision parts for industries such as aerospace and medical.
High machinability and ductility, good strength-to-weight ratio. Aluminum alloys have good strength-to-weight ratio, high thermal and electrical conductivity, low density and natural corrosion resistance. Can be anodized.
High tensile strength, corrosion and temperature resistant. Stainless steel alloys have high strength, ductility, wear and corrosion resistance. They can be easily welded, machined and polished.
High machinability and weldability, high stiffness. Mild steels are low-carbon metal alloys offering good mechanical properties, machinability and weldability at low cost. Can be carburized to increased hardness.
Excellent thermal and electrical conductivity Copper offers excellent thermal and electrical conductivity, it's often used for busbars, wire connectors, and other electrical applications. Copper has a glossy reddish-orange appearance.
Excellent strength to weight ratio, used in aerospace, automotive and medical industries. Titanium is a metal with excellent strength-to-weight ratio, low thermal expansion and high corrosion resistance that is sterilizable and biocompatible.
Tool steel has high hardness and can maintain high hardness and red hardness at high temperatures, as well as high wear resistance and appropriate toughness. Tool steel is generally divided into carbon tool steel, alloy tool steel and high-speed tool steel.
Superalloys have excellent high-temperature strength, good oxidation resistance and hot corrosion resistance, good fatigue properties, fracture toughness and other comprehensive properties, and are mainly used in the aerospace and energy fields.
Brass has strong wear resistance, high strength and hardness, and strong resistance to chemical corrosion. Brass is often used to make wear-resistant parts such as valves and watch movements.
Alloy steel has special properties such as high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, and magnetism.
Engineering plastics have excellent comprehensive properties, such as high rigidity, low creep, high mechanical strength, good heat resistance, and good electrical insulation. They can be used in harsh chemical and physical environments for a long time and can replace metals as engineering structural materials.

Aerospace (engine components), automotive manufacturing (transmission housings), medical devices (implants), and heavy machinery, particularly suitable for the machining of complex multi-faceted and deep-hole parts.
5 axes can simultaneously control 5 motion axes, enabling complex surface machining (such as turbine blades) to be completed in a single clamping operation; 3 axes can only move linearly, making them suitable for simple planes or grooves.
The minimum wall thickness for CNC machining varies significantly based on multiple factors. For soft metals like aluminum, it can typically be as low as 0.5mm, while harder materials such as stainless steel or titanium usually require a minimum of 1mm to prevent tool breakage and maintain structural integrity during machining. Engineering plastics like ABS or POM allow for thinner walls, often reaching 0.3mm. However, complex geometries, deeper cavities, and the specific capabilities of the CNC machine, especially 5-axis machines that can optimize cutting angles, also play crucial roles. Advanced 5-axis CNC setups may enable even thinner walls down to 0.3mm by reducing tool deflection, but this requires precise programming and careful material selection.
Compliant with ISO 1984-1 (accuracy testing) and ISO 3070-4 (heavy machine tool testing), the aviation sector can meet AS9100D certification.
Using 360° indexing table and multi-axis linkage technology, complex features such as spiral grooves and inclined holes can be completed in a single clamping, with a surface roughness of Ra≤0.8μm.
