Full Process Process Breakdown
Drawing Analysis & DFM Optimization
Our engineers respond to demands within 3 minutes and provide free quotations plus DFM reports within 4 hours. We eliminate structural interference, unreasonable tolerances and other hidden troubles in advance to cut scrap risks.
Precision Programming & Simulation
We adopt professional software including UG and Mastercam to compile exclusive machining programs for complex curved surfaces, thin-wall structures and deep cavity features. Cutting path simulation prevents collision and deformation, ensuring consistent machining quality.
Differentiated Cutting Processes
- Rough Machining: Adopt 2-5mm deep cutting depth with matched spindle speed to remove excess material efficiently.
- Semi-finishing: Layered cutting with 0.1-0.5mm finishing allowance reserved to balance precision and productivity.
- Finishing: Small cutting depth plus high rotating speed, equipped with CBN and diamond coated cutters to strictly control geometric tolerances and achieve superior surface finish.
Strict Quality Inspection & Traceability
Full dimensional inspection via CMM, real-time monitoring on key working procedures. Each product is marked with an exclusive traceability code. Material certificates, hardness test reports and inspection records are fully accessible for review.
Core Process Advantages
5-axis linkage machining realizes processing of five surfaces in one clamping, minimizes positioning errors, and easily handles complex curved parts such as turbine impellers and aerospace guide vanes.
Turn-milling composite technology integrates turning, milling, drilling, tapping and other processes. Multiple procedures are finished in one clamping, cutting production cycle by over 30% and improving coaxiality and perpendicularity precision of parts.
Low-temperature cutting & high-pressure cooling: For hard-to-machine materials like titanium alloy and superalloy, we apply -196℃ liquid nitrogen cryogenic cutting together with 70-100bar high-pressure cooling to reduce cutting heat, lower tool wear and restrain work hardening.
What others cannot do, we can: Break through tough industrial technical barriers
Many manufacturers dare not take orders, fail to produce or struggle with poor precision when it comes to complex hard-to-machine parts. Backed by powerful equipment, mature craftsmanship and rich practical experience, Zorapid breaks technical bottlenecks. We undertake custom processing of ultra-high precision, ultra-complex and difficult-to-machine components, turning impossibility into reality.
1. Ultra-high Precision Thin-wall Part Machining
Pain Points: Wall thickness ≤0.5mm, prone to deformation and vibration, tolerance requirement up to ±0.005mm. The scrap rate of traditional processing exceeds 50%.
Our Solutions: Adopt flexible vacuum chuck clamping, layered cutting and low-stress cutting parameters. Supported by constant-temperature workshop at 22℃±1℃ to restrain thermal deformation. We maintain a stable yield rate above 99%. Available for thin-wall sleeves, sensor housings and other workpieces made of titanium alloy, aluminum alloy and stainless steel.
Complex Parts Made of Hard-to-Machine Materials
Pain Points: Materials such as Ti-6Al-4V titanium alloy, Inconel 718 superalloy and 17-4PH stainless steel feature high hardness, poor thermal conductivity, severe tool adhesion and obvious work hardening, leading to short tool service life and unstable dimensional accuracy.
Our Solutions: We adopt customized CBN and coated carbide cutting tools, optimize machining parameters of low spindle speed, high feed rate and moderate cutting depth, and equip high-pressure chip breaking systems. We can steadily process aero-engine blades, medical implants, high-pressure valve bodies and other qualified components with consistent precision.
Micro Hole / Deep Cavity / Special-Shaped Structural Parts
Pain Points: Hole diameter ≤0.1mm, depth-diameter ratio ≥20:1, complex inner cavities and abundant irregular curved surfaces. Conventional equipment fails to process such workpieces easily, causing frequent tool breakage and poor chip removal.
Our Solutions: Equipped with high-speed spindles, micro drills and micro milling cutters, combined with dedicated chip removal technology and ultrasonic vibration-assisted machining. We are capable of manufacturing precision medical valve cores, electronic connectors, optical components and more, with the minimum machinable hole diameter reaching 0.05mm.
Large-size & Heavy-weight Precision Components
Pain Points: Parts over 1m in size and 500kg in weight face difficult clamping, large positioning deviation and uneven cutting stress, which easily cause deformation and unstable precision.
Our Solutions: We deploy large 5-axis gantry machining centers and customized tooling fixtures. Segmented machining plus stress relief treatment including vibration aging and heat treatment effectively eliminate internal stress. We process large molds, aerospace casings, automation equipment frames and more, achieving flatness within 0.02mm per meter.
