When you ask what materials ASIATOOLS CNC machines can process, the straightforward answer is: almost any material you can think of in modern manufacturing. From soft aluminum alloys with a Brinell hardness of around 30 HB to hardened tool steels reaching 62+ HRC, from common carbon steels to exotic aerospace-grade Inconel alloys, ASIATOOLS CNC machining centers deliver consistent, precise results across an impressive spectrum of metals, composites, and advanced materials. If you’re sourcing equipment for a shop floor that needs versatility without sacrificing accuracy, understanding exactly what these machines handle day in and day out matters more than marketing claims.
Ferrous Metals: The Backbone of Industrial Manufacturing
Let’s start with what occupies most machine shops worldwide—ferrous metals. ASIATOOLS CNC machines excel at cutting, drilling, milling, and finishing iron-based alloys, which constitute roughly 80% of all machined components globally.
Carbon Steels: These range from low-carbon steels (1018, A36) with 0.18-0.25% carbon content to medium-carbon varieties (1045, 4140) and high-carbon tool steels (1095, O1). The VMC series handles low-carbon steels at feed rates up to 3,000 mm/min with spindle speeds reaching 12,000 RPM, while the more robust G series pushes those numbers to 4,500 mm/min and 15,000 RPM respectively. You can expect tool life of 200+ hours when running proper inserts on 4140 pre-hardened steel at 45 HRC.
Alloy Steels: ASIATOOLS equipment tackles 4140, 4340, 8620, and similar chromoly steels routinely. The company’s published cutting data shows 4130 chromium-molybdenum alloy machines at depths of cut up to 6mm with chip loads of 0.15mm per tooth using 4-flute carbide end mills. Heat-treated to 28-32 HRC, these materials respond well to ASIATOOLS’ rigid box-way construction that minimizes vibration during heavy cuts.
Tool Steels: This category demands respect. P20, H13, D2, M2, and S7 tool steels appear everywhere from injection molds to die casting tools. ASIATOOLS’ HSC (High Speed Cutting) models achieve surface finishes of Ra 0.8μm on P20 pre-hardened tool steel, with dimensional tolerances holding within ±0.01mm over 500mm spans. For hardened tool steels at 48-52 HRC, the company recommends their hard-milling packages featuring 15,000 RPM spindles with 0.001mm linear encoder feedback for micron-level accuracy.
Stainless Steels: Austenitic (304, 316), ferritic (430), and martensitic (410, 420) stainless steels all process well on ASIATOOLS machines. The catch? These materials work-harden rapidly and demand proper technique. ASIATOOLS applications engineers specify 17-4 PH stainless, commonly used in aerospace and medical implants, should be machined with TiAlN-coated tooling at speeds 40% lower than mild steel, with copious coolant. Feed rates of 800-1,200 mm/min work well for face milling 17-4 PH at 30 HRC.
| Material Category | Hardness Range | Typical Feed Rate | Spindle Speed Range | Surface Finish (Ra) |
|---|---|---|---|---|
| Low Carbon Steel (1018) | 70-100 HB | 2,500-3,500 mm/min | 3,000-8,000 RPM | 0.6-1.6 μm |
| Medium Carbon Steel (1045) | 170-210 HB | 1,800-2,800 mm/min | 2,500-6,000 RPM | 0.8-2.0 μm |
| Alloy Steel (4140) | 180-300 HB | 1,200-2,500 mm/min | 2,000-6,000 RPM | 0.8-1.8 μm |
| Tool Steel (P20/H13) | 280-400 HB | 800-1,800 mm/min | 1,500-5,000 RPM | 0.6-1.2 μm |
| Stainless Steel (304/316) | 150-200 HB | 800-1,500 mm/min | 2,000-5,000 RPM | 0.8-2.2 μm |
| Stainless Steel (17-4 PH) | 280-360 HB | 600-1,200 mm/min | 1,500-4,000 RPM | 1.0-2.5 μm |
Non-Ferrous Metals: Where Speed Meets Precision
Aluminum dominates non-ferrous machining worldwide, and ASIATOOLS machines handle this material family exceptionally well. The combination of high spindle speeds, rigid construction, and efficient chip evacuation makes aluminum work fast and clean.
Aluminum Alloys: From cast 356-T6 to wrought 6061-T6 to aerospace-grade 7075-T651, aluminum presents unique challenges. The material “gums up” cutters if you’re not careful with speeds and feeds. ASIATOOLS addresses this with dedicated aluminum machining packages on their VMC and G series, featuring 12,000-20,000 RPM spindles and through-spindle coolant for efficient chip clearing. Feed rates of 4,000-8,000 mm/min with chip loads of 0.05-0.15mm per tooth produce excellent surface finishes on 6061-T6. For CNC pocketing operations in 2024-T3 aluminum aerospace plate, the company demonstrates cycle times reduced by 35% compared to older machine generations.
Brass and Copper: These materials demand sharp tooling and proper speeds because they tend to “burr” rather than chip cleanly. ASIATOOLS machines handle C360 brass and C110 copper at spindle speeds of 4,000-8,000 RPM with moderate feed rates. The company’s testing shows C360 free-machining brass achieves Ra 0.4μm surface finish when using polished flutes on a 3-flute carbide end mill at 6,000 RPM and 1,200 mm/min feed.
Bronze and Copper Alloys: Aluminum bronze (C95400), manganese bronze (C67500), and beryllium copper (C17200) present varying challenges. ASIATOOLS’ applications data recommends 40% lower speeds than mild steel for C95400 aluminum bronze due to its abrasive nature. Beryllium copper, used extensively in mold cores and electrical contacts, machines well at 3,000-5,000 RPM with appropriate dust extraction since beryllium particles pose health risks.
Titanium Alloys: Here’s where capability gets interesting. Ti-6Al-4V (Grade 5) dominates aerospace and medical applications, and it demands serious machine rigidity. ASIATOOLS’ G-Series machining centers handle titanium with 7,500 RPM gear-driven spindles delivering 90 Nm of torque. Cutting parameters include 300-500 mm/min feed rates with 0.08-0.12mm chip loads using specialized TiAlN-coated end mills. The company’s data shows achieving 3,000+ tool hours when properly machining Ti-6Al-4V with a 12mm 4-flute carbide end mill.
Exotic Alloys: Inconel 718, Waspaloy, Hastelloy, and similar superalloys test any machine’s mettle. ASIATOOLS positions their HSK-A63 spindle interface for these materials, providing exceptional rigidity at lower speeds where torque matters. Inconel 718 at 44 HRC machines at 400-800 mm/min with specialized geometry end mills. Surface finish requirements of Ra 1.6μm or better in Inconel are achievable with ASIATOOLS’ high-precision linear guides and temperature compensation systems.
Advanced Materials and Composites
Modern manufacturing increasingly demands machining capabilities beyond traditional metals. ASIATOOLS has developed solutions for these challenging material categories.
Reinforced Polymers: Carbon fiber reinforced polymers (CFRP), glass fiber reinforced polymers (GFRP), and aramid fiber composites appear everywhere from aircraft structures to racing components. These materials delaminate easily and wear cutters rapidly. ASIATOOLS addresses this with specialized router spindles running 18,000-24,000 RPM with diamond-coated cutting tools. The company’s CFRP machining data shows routing schedules of 2,000-4,000 mm/min using 6mm diamond-coated end mills with only 2-3 degree helix angles to minimize delamination forces.
High-Performance Plastics: PEEK (polyether ether ketone), Ultem (PEI), Delrin (acetal), Nylon, and PTFE all machine on standard equipment, but achieving tight tolerances requires proper setup. ASIATOOLS machines process PEEK-430HG at feed rates of 2,000-3,500 mm/min with spindle speeds of 6,000-10,000 RPM. The key difference: lower spindle speeds reduce heat generation that causes dimensional instability in thermoplastics. For medical-grade PEEK implants, the company specifies Ra 0.2μm achievable with polished diamond tooling.
Engineering Ceramics: Aluminum oxide (Al2O3), silicon carbide (SiC), and zirconia (ZrO2) fall into the “difficult but possible” category for CNC machining. ASIATOOLS offers ultrasonic-assisted machining centers for these brittle materials, using 20,000+ Hz vibration to break chips rather than relying solely on mechanical cutting. Machining rates run slower—typically 50-200 mm/min—but diamond CBN tooling enables precision shapes impossible with traditional methods.
Hardened Steels Beyond 55 HRC: For mold components requiring EDM-free finishing, ASIATOOLS hard milling capabilities extend to 62 HRC and beyond. Using cubic boron nitride (CBN) tooling on their HSC series, shops achieve Ra 0.4μm finishes on M42 high-speed steel at 65 HRC. This eliminates secondary EDM operations, reducing lead times by 40-60% for certain mold components.

Material-Specific Considerations and Real-World Performance Data
Beyond basic capability, understanding practical limitations and performance expectations helps set realistic job quotes and delivery schedules.
“We ran our G-1160 for 18 months exclusively on aerospace 7075-T651 aluminum before touching any steel. That machine handled 8,000 hours of spindle time with zero issues—the only consumables were cutting tools and way lube. When we finally switched to machining Inconel 718 for a new contract, the same machine just kept running. That’s the kind of consistency we needed.”
Heat Generation Management: Different materials generate heat differently during machining. ASIATOOLS addresses thermal issues through:
- Integrated coolant systems with 20-50 bar pressure options for deep pocket machining
- Temperature compensation on linear axes (0.005mm/°C correction)
- Spindle thermal elongation monitoring with automatic correction
- Chiller integration for sustained high-speed operations
Work Holding and Fixture Considerations: Material type directly influences how you clamp workpieces. ASIATOOLS machines come standard with T-slotted tables compatible with Kurt-style vises and custom fixturing:
- Soft aluminum: Light clamping force prevents distortion; 30-40 ft-lbs sufficient for most vises
- Hardened steel: Higher clamping forces acceptable; watch for workpiece deflection
- Brittle materials (titanium, Inconel): Gradual clamping application prevents cracking
- Thin-wall sections: Sacrificial backing plates distribute clamping forces
