Raw Material Preparation Spectrum
Three dedicated raw material preparation workflows — from heavy-duty CNC band sawing of ingots to mechanical surface peeling and chemical decontamination — ensuring downstream-ready titanium stock.
Heavy-Duty CNC Band Sawing
Precision Ingot & Billet SectioningIndustrial-scale CNC band sawing stations for precision sectioning of titanium ingots, billets, and blocks — achieving square-cut tolerances within ±1.5 mm on cross-sections up to 800 mm diameter.
- Ingot sectioning up to 800 mm diameter — hydraulic clamping with programmable blade feed optimization
- Automatic blade tension monitoring and carbide-tipped blade selection for titanium-specific cutting parameters
- Coolant-fed cutting zone with biocide-treated emulsion — preventing bacterial growth during extended cut cycles
- Integrated material handling: auto-loading from storage rack, precision cutting, and discharge to inspection station
CNC Mechanical Surface Peeling
Defect Layer Removal & Surface ConditioningSpecialized CNC peeling lathes remove the alpha-case layer, surface cracks, and scale from titanium billets and bars — achieving clean, defect-free surfaces ready for downstream forging or extrusion.
- Peeling depth control within ±0.1 mm — removing 1-5 mm per pass depending on prior surface condition
- Multi-pass peeling with intermediate ultrasonic inspection to verify complete defect layer removal before final pass
- Automated chip management system with dedicated titanium chip collection for recycling and material yield tracking
- Surface roughness after peeling: Ra 1.6-3.2 µm — ready for direct downstream processing without additional conditioning
Chemical Decontamination & Passivation
Deep Clean for Critical AlloysControlled chemical bath processing for deep cleaning of titanium surfaces — removing embedded contaminants, oxide scales, and surface oxides from raw stock before premium-grade manufacturing operations.
- Multi-stage bath sequence: alkaline degrease → hot rinse → acid pickle → final DI water rinse — each stage temperature and time controlled
- Acid pickle formulation optimized per titanium grade — HF/HNO₃ ratio adjusted for Grade 2, Grade 5, and Grade 23 alloys
- Post-process surface verification: water break test per ASTM F22 and residual contamination check per ASTM F24
- Batch-level documentation: each lot tracked with immersion time, bath temperature, chemical concentration, and surface verification results
Material Prep Capacity Dashboard
Our raw material preparation capacity — maximum sawing diameter, square-cut tolerance, peeling depth control, and material verification metrics.
Max Sawing Diameter
Maximum cross-section capacity of our industrial CNC band sawing stations — accommodating large titanium ingots and billets up to 800 mm diameter in a single cut.
Square-Cut Tolerance
Achievable squareness and length tolerance on saw-cut titanium sections — verified by physical measurement on every cut face before downstream processing.
Peeling Depth Control
CNC-controlled peeling depth range for alpha-case and surface defect removal — programmable per pass to optimize material yield while ensuring complete defect layer elimination.
Material Verification Rate
100% Positive Material Identification (PMI) via OES spectrometry on every incoming batch — confirming grade chemistry before any material preparation begins.
All specifications measured under controlled conditions per ASTM and AMS standards. Actual results depend on material grade, geometry, and surface condition.
Hardening Suppression & Traceability Control
Raw titanium preparation demands thermal damage prevention and unbroken material chain-of-custody. Here's how we eliminate work-hardening and lock down heat-number traceability through the entire production flow.
Chilled-Fluid Runaway Suppression
During high-power band sawing and mechanical peeling of titanium, the intense friction generates localized temperatures that can exceed 600°C at the cutting interface — approaching titanium's beta transus temperature. This thermal buildup causes micro-structural phase transformations (grain coarsening, alpha-case formation) on the cut surface, creating a work-hardened layer that accelerates blade wear and reduces downstream forging tool life by up to 40%.
High-Pressure Fully Synthetic Flood Cooling Directly into the Saw Kerf
- High-pressure flood cooling at 15-25 bar delivering fully synthetic coolant directly into the saw kerf and peeling interface — the coolant jet penetrates the chip-tool contact zone, evacuating heat before it can diffuse into the subsurface microstructure
- Synthetic coolant formulation (water-soluble polymer-based, 5-8% concentration) provides superior lubricity and heat extraction compared to standard soluble oils — thermal conductivity at the cutting interface is increased by 300%, keeping the workpiece surface temperature below 150°C at all times
- Through-blade coolant delivery: the band saw blade has precision-drilled micro-channels that deliver coolant to each tooth tip — ensuring every cutting edge is lubricated and cooled at the point of contact, eliminating localized hot spots that cause thermal cracks and blade glazing
- Result: cut surfaces with zero micro-structural alteration — no alpha-case formation, no grain coarsening, no work-hardened layer. Blade life extended by 35% and downstream forging tool life preserved by eliminating hard surface skins that accelerate die wear
Unbroken Heat-Number Laser Interlock
In multi-ton titanium processing, material traceability from mill certificate through sawing, peeling, and decontamination to the final forged or extruded component is critical for aerospace and defense compliance. Traditional manual label or paint-mark systems are destroyed during 1000°C furnace heating cycles or multi-ton compression, breaking the chain-of-custody and requiring expensive re-certification or component scrapping.
Mill Test Certificate Digital Binding & Fiber-Laser Marking on Sliced Blanks
- Mill Test Certificate (MTC) data is digitally ingested into the batch management system at material receipt — including heat number, chemical composition (%Al, %V, %Fe, %O, %N), mechanical properties, and ultrasonic inspection results — creating a digital twin for each incoming ingot or billet
- Fiber-laser marking system applies a unique 2D Data Matrix code directly onto each sliced blank after sawing — the code is engraved 0.1-0.3 mm deep, surviving multi-ton compression forces (8,000 tons) and 1000°C furnace thermal cycles without degradation
- The 2D code encodes: heat number, billet sequence number, alloy grade, cut date, and operator ID — scannable via handheld reader at any point in the production flow, from sawing through forging, extrusion, heat treatment, and final machining
- Full digital chain-of-custody: every processing step (peeling depth, passivation batch, PMI verification result) is appended to the digital twin record, creating an unbroken traceability chain from mill to finished component — compliant with AS9100D, AMS 2750, and NIST traceability requirements
