CNC Grinding Materials

CNC Grinding is versatile and can be applied to a wide range of materials, both metal and plastic, each with its own set of characteristics.

Aluminum Alloys

Common grades include 6061, 7075, and 2024. They are favored for their ease of machining but require proper cleaning and protection post-processing due to oxidation.

Properties:

Lightweight
High strength-to-weight ratio
Good electrical and thermal conductivity
Corrosion resistant

Applications:

Aerospace: aircraft frames, engine parts
Electronics: heat sinks

Steel

Grades like 304 and 316 are popular for their durability and aesthetic appeal, though they are more challenging and costly to machine.

Properties:

Excellent corrosion resistance
High strength
Heat resistant

Applications:

Automotive: engine components like crankshafts and camshafts
Machinery manufacturing industry: gears, shafts, various structural parts

Titanium Alloys

Despite its high cost and difficulty in machining, titanium’s exceptional properties make it indispensable in high-performance applications.

Properties:

High strength-to-weight ratio
Corrosion resistant
Biocompatible

Applications:

Aerospace: turbine blades, aircraft structural parts
Medical: artificial joints

Polycarbonate (PC)

Engineering plastics (e.g., ABS, POM, PC, PMMA) offer a balance of lightweight, cost-effectiveness, and ease of machining, although they may lack the heat resistance and strength of metals.

Properties:

High impact resistance
Excellent optical clarity
Good heat resistance
Good electrical insulation properties

Applications:

Automotive: headlight lenses, interior lighting covers, safety shields.
Electronics: display screens, computer cases, optical components.
Safety Equipment: safety glasses, face shields, bullet-resistant windows

Glass Fiber Reinforced Polymer (GFRP)

Engineering plastics (e.g., ABS, POM, PC, PMMA) offer a balance of lightweight, cost-effectiveness, and ease of machining, although they may lack the heat resistance and strength of metals.

Properties:

Good strength and stiffness at a relatively low cost
Excellent corrosion resistance
Good electrical insulation properties
Can be molded into complex shapes

Applications:

Construction: building facades, roofing materials, structural components
Marine: boat hulls, decks, interior fittings
Electrical: electrical enclosures, insulators, circuit boards

CNC Grinding Surface Finishing

Powder Coating

Durable, corrosion-resistant finish with customizable colors/textures.

Anodizing

Enhances corrosion resistance, improves surface hardness, and offers aesthetic color options.

Polishing/Buffing

Achieves smooth or mirror-like finishes by reducing surface irregularities.

Passivation

Removes free iron contaminants and enhances stainless steel’s corrosion resistance.

Electropolishing(e.g., Nickel, Chrome, Zinc)

Provides wear resistance, electrical conductivity, and decorative finishes.

Sandblasting/Shot Peening

Reduces surface roughness, removes burrs, and improves adhesion for coatings.

Why Fecision for CNC Machining?

Traditional machining methods may not be able to deal with complex geometries and high-precision parts. Our multi-axis machines, ranging from 3-axis to 5-axis CNC machines, enable us to perform intricate cuts, angles, and curves.

Experienced Engineering Team

Our engineering team has decades of experience in CNC machining and design optimization. At Fecision, we specialize in Design for Manufacturability (DFM) and leverage advanced CAD/CAM software to ensure smooth integration between design and machining processes.

Versatility Across Materials

Fecision offers a broad spectrum of material options to match the needs of your specific application. Meanwhile, we provide guidance on material selection based on part performance requirements such as strength, corrosion resistance, or wear resistance, ensuring optimal results.

Quality Assurance

Our products are trusted by high-profile customers from industries across global, meeting strict and complete quality standard. Access to ISO 9001: 2015 quality certification and our manufacturing partners certified to ISO 13485: 2016, ISO 14001: 2015, and IATF 16949: 2016.

Fast Turnaround Times

Fecision recognizes the critical need for timely delivery. Most machines of our partner manufactuers run 7*24 hours with integrated process. Through streamlined workflows and optimized production processes, we ensure fast lead times while maintaining the highest standards of quality.

Commitment to Sustainability

Fecision is committed to minimizing waste and reducing our environmental impact. We prioritize sustainable practices such as material recycling, energy-efficient operations, and waste reduction in our machining processes.

Start CNC Machining

Once your parts are designed and optimized for CNC machining, it's time to move forward with the manufacturing process. It only takes 4 steps as followed.

Submit Technical Files

Export your design to a CNC-compatible CAD file format. For CNC machining, we advise STEP format as it’s more standardized and can be used across platforms. It would be better if you can provide a technical drawing, especially when your design contain threads, specified tolerances or need a different finishing.

DFM & Quotation

We will provide a DFM (Design for Manufacturability) report to detect any potential design issues before production begins. Please be aware that further discussions may be needed during the process.
