Question 1

What is the Minimum Order Quantity (MOQ) for your CNC machining services?

Accepted Answer

Fedele Autocore provides flexible order quantities for CNC machining services, ranging from single prototype pieces (1 unit) to high-volume bulk production runs. We scale production seamlessly to match your exact project requirements.

Question 2

Can you provide pre-production sample parts before commencing bulk production?

Accepted Answer

Yes, for all bulk production orders, Fedele Autocore provides pre-production sample parts first. This ensures 100% quality, dimensional accuracy, tolerance validation, and design assurance before launching full mass manufacturing.

Question 3

What is your guarantee if delivered components have specification mismatches or wrong delivery?

Accepted Answer

Fedele Autocore guarantees 100% Product Replacement Assurity. In the rare event of any dimensional mismatch, specification deviation, or incorrect delivery, we immediately replace 100% of the affected products at zero additional cost.

Question 4

What multi-axis CNC machining equipment does Fedele Autocore operate?

Accepted Answer

We operate 3-axis, 4-axis, and 5-axis VMCs, live-tooling CNC turning centers, and Swiss automatic screw machines.

Question 5

What positioning accuracy and repeatability do your CNC machines maintain?

Accepted Answer

Our machines maintain positioning accuracy of ±0.005mm and bi-directional repeatability of ±0.0025mm.

Question 6

What surface finishes can be achieved through CNC machining?

Accepted Answer

Standard as-machined finish is Ra 1.6µm, fine finish Ra 0.8µm, and precision ground finish down to Ra 0.2µm.

Question 7

What quality certifications back your CNC machining services?

Accepted Answer

We are ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and ISO 50001:2018 certified.

Question 8

What CAM programming software is used for multi-axis toolpaths?

Accepted Answer

We utilize Mastercam, Siemens NX, and SolidWorks CAM for high-efficiency dynamic milling and turning toolpaths.

Question 9

What post-machining heat treatments and platings do you provide?

Accepted Answer

We offer carburizing, nitriding, induction hardening, anodizing, electroless nickel, and zinc-flake coating.

Question 10

Is stainless steel magnetic after CNC machining?

Accepted Answer

Raw austenitic stainless steels (such as Grade 304 and 316L) are completely non-magnetic in their annealed form. However, during high-speed CNC turning, milling, and cold shearing, severe plastic deformation induces a microstructural phase change where part of the face-centered cubic (FCC) austenite structure transforms into body-centered tetragonal (BCT) martensite. This strain-induced martensite creates slight magnetic permeability along machined edges and thin walls. Where zero magnetism is critical (such as MRI components or aerospace guidance systems), Fedele Autocore provides post-machining full solution annealing at 1,050°C to restore complete non-magnetic properties.

Question 11

Can Fedele Autocore CNC machine PEEK and advanced engineering plastics?

Accepted Answer

Yes. We precision machine high-performance engineering thermoplastics including PEEK (unfilled, 30% carbon-filled, and 30% glass-filled), Delrin/Acetal (POM), PTFE (Teflon), UHMW-PE, and Nylon 6/6. PEEK provides exceptional chemical resistance, flame retardance, and continuous operating temperatures up to 250°C for aerospace and biocompatible medical implants. We employ polished micro-grain carbide tooling, cold air blast cooling, and stress-relieving heat cycles to eliminate part distortion and maintain ±0.01mm tolerances.

Question 12

What is the melting point of stainless steel and alloy steel in CNC manufacturing?

Accepted Answer

The melting point of steel varies by composition: carbon steels melt between 1,425°C and 1,540°C (2,600°F–2,800°F), austenitic stainless steels (304 and 316L) melt between 1,400°C and 1,455°C (2,550°F–2,650°F), and precipitation-hardening 17-4PH melts at 1,404°C–1,440°C. In high-speed CNC milling and turning, tool-chip interface temperatures can exceed 750°C, requiring high-pressure through-spindle coolant to maintain dimensional integrity and avoid surface thermal degradation.

Question 13

How do 304, 304L, Alloy 316, and 17-4PH stainless steel properties compare for CNC machining?

Accepted Answer

Grade 304/304L offers balanced corrosion resistance and 515 MPa tensile strength, making it the most economical choice for food equipment, automotive brackets, and general industrial enclosures. Alloy 316/316L contains 2–3% molybdenum, providing superior resistance to pitting and crevice corrosion in marine, pharmaceutical, and subsea chloride environments. Grade 17-4PH (UNS S17400) is a martensitic precipitation-hardening alloy achieving ultra-high tensile strength up to 1,310 MPa and 44 HRC hardness in Condition H900, ideal for high-stress aerospace pump shafts, valve stems, and hydraulic spools.

Question 14

What capabilities does Fedele Autocore offer for machining Inconel superalloys?

Accepted Answer

We machine Inconel 718 and Inconel 625 nickel-chromium superalloys for high-temperature turbine components and subsea oil & gas assemblies. Inconel retains high tensile strength (up to 1,375 MPa) and corrosion resistance at service temperatures exceeding 650°C (1,200°F). Our multi-axis CNC centers use ceramic and whisker-reinforced carbide tooling with rigid setups and positive rake geometries to overcome high work-hardening rates.

Question 15

What CNC machining capabilities are available for ABS, Acrylic, HDPE, PP, and specialty polymers?

Accepted Answer

Fedele Autocore precision machines a complete range of production plastics including ABS (high impact strength for automotive prototypes), optical PMMA Acrylic (crystal-clear light transmission), HDPE and PP/PPH (chemical tanks and food machinery guides), PETG (durability and chemical resistance), Polyurethane (PU damping pads), and Aluminum Composite Material (ACM panels). Using razor-sharp single-flute carbide end mills and cold-air vortex cooling prevents burring, melting, or surface crazing.
