CNC machine example: key types

Unlocking manufacturing potential: Required CNC machine types and their applications

CNC (Computer Numerical Control) processing is the cornerstone of modern precision manufacturing. By converting digital designs into tangible metal and plastic components with unparalleled precision, CNC technology can drive innovation in aerospace, medical, automotive and countless other industries. The diversity of today’s available CNC machines ensures that you can meet almost any design challenge and protect you from choosing the right work tool. Let’s explore the key types of CNC machines and their unique problems to solve.

CNC Toolbox: Key Machines and Real-World Examples

Not all CNC machines can run. Each category excels in specific schemes, balance accuracy, speed, complexity, and material functions:

1. CNC milling machine: shape master

   • How they work: The rotary cutting tool removes material from the fixed workpiece from multiple shafts.
   • Key changes and examples:

     • 3-axis mill: Main ground for basic work. example: Generates engine blocks (plane, pocket, drilled).
     • 4-axis mill: Add workpiece rotation (A-axis). example: Process the complex profile around the camshaft or cylinder.
     • 5-axis mill (professional): Move the tool/part (X, Y, Z + A&B rotation) on five axes simultaneously. example: Aerospace turbine blades, complex medical implants, impellers. This technology allows unparalleled geometric freedom and efficiency, eliminating multiple settings and improving the accuracy of organic shapes.

   • Material range: Metal (aluminum, steel, titanium), engineering plastic.

2. CNC lathe (turning center): Master of Symmetry

   • How they work: The workpiece rotates when the fixed cutting tool shapes its exterior/interior. Ideal for cylindrical or conical parts.
   • Example: Precision shafts, hydraulic accessories, custom fasteners, Bushing, nozzle.
   • Advanced version: The multitasking steering mill center combines turning and milling functions in one machine. example: To process the transmission shaft, the rotation diameter and milling key change/pattern are required.
   • Material range: Metal, plastic, wood.

3. CNC router: material processing power

   • How they work: Similar to the mill movement, it is usually optimized for larger workpieces and less extreme cutting forces.
   • Example: Sheet metal manufacturing (panels), intricate wood products (furniture, cabinets), logo manufacturing, plastic prototypes, Cutting composite materials for aerospace panels.
   • Material range: Wood, plastic, composite, non-producing gold (aluminum), foam.

4. CNC plasma cutter: fast 2D analysis

   • How they work: The conductive plasma melted along the programmed 2D path is melted through the metal plate.
   • Example: Quick cut structural frame, artistic metal sculpture, custom bracket steel plate. Stand out with good surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface surface velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity velocity
   • Material range: Conductive metal (steel, stainless steel, aluminum – thickness dependency).

5. CNC Electrical Emission Machine (EDM): Conquer super hard and accurate

   • How they work: Use controlled electric sparks to erode the material without direct contact. Great for hardening metals.
   • Key types and examples:

     • Wire EDM: Use thin wires. example: Cut super exquisite molds for punching tools, hardening tool steel gears (HRC 60+).
     • Pendant EDM (sinking): Use shape electrodes. example: Create complex cavity in molds for injection molding or forging.

6. CNC grinder: Precision completion expert

   • How they work: Use abrasive wheels to achieve extremely high surface surfaces and maintain microscopic tolerances.
   • Example: Precision shaft, automotive bearing race, cutting tool geometry (end mill, insert), Optical components.
   • Material range: Hard metal, ceramic, composite materials.

Choose the right machine: The choice depends on the partial geometry, complexity, material, required tolerances, surface finish and volume. Simpler 2.5D parts thrived on 3-axis or routers. Complex 3D profiles require 4-axis or 5-axis functions. The high volume rotating component rests on the CNC lathe. Hardened steel requires EDM or grinding.

Improve complexity: Why 5-axis CNCs become the center stage

For prototyping and production, complex geometry of complex curves, undercuts or precise angles on multiple faces (such as aerospace actuators, robotic arms, or customized medical devices), and 5-axis CNC machining is essential. GREMLIGHT leverages this advanced technology to achieve its maximum potential. Our capabilities go beyond simple milling:

CNC machining FAQ: Your question has been answered

Q1: What kind of 5-axis CNC machine can’t be done by a 3-axis machine?

A: When a 3-axis machine moves the cutting tool in X, Y and Z (linear directions), a 5-axis machine adds two rotation axes (usually A and B). This allows the cutting tool to approach the workpiece from almost any direction In a setting. The key advantages are:

• It is impossible to use 3 axes to process the composite shape with deep bags, undercut or composite angles.
• Setting time and potential errors are significantly shortened (because the section is not relocated manually).
• Upper surface finish on complex contours.
• Ability to use shorter cutting tools for improved stiffness and vibration-free operation for better accuracy.

Q2: Which materials can use 5-axis CNC Greatlight Machine?

A: We specialize in a wide variety of processable materials. This includes:

• Metal: Aluminum alloy (6061, 7075), stainless steel (303, 304, 316 and 17-4ph), titanium (grade 2, grade 5, 5-ti6al4v), brass, copper, tool steel, carbon steel, carbon steel.
• Plastics/Composites: PEEK, DELRIN (acetyl), nylon, ULTEM (PEI), PTFE (Teflon), acrylic acid (PMMA), polycarbonate, ABS, ABS, engineered composites.
• We recommend the best material selection for your features, budget and manufacturing.

Q3: Apart from processing, what "One-stop" Do you provide post-processing services?

A: To provide fully finished parts, Greatlight provides comprehensive post-processing under one roof:

• Surface finish: Anodized (type II, type III hard coating), electroplating (nickel, chromium, zinc), powder coating, paint, polishing/bead blasting.
• Heat treatment: Stress relief, annealing, hardening/tempering, quenching, case hardening.
• other: Part marking (laser engraving, pointing disk), precision cleaning, non-destructive testing (NDT), assembly/kit.
• This ensures consistency, reduces lead times and simplifies your supply chain.

Q4: What file format is required to reference custom CNC parts?

A: We prefer 3D solid model files (recommended steps or IGE) because they provide the most explicit geometry. 2D plots (PDF or DWG/DXF) with full GD&T (geometric dimensions and tolerances) specifications are also essential for critical dimensions and inspections. If you only have concept sketches, we can assist in designing manufacturability (DFM) and modeling.

Question 5: How do you ensure the quality and accuracy of complex 5-axis machining parts?

A: The quality has been embedded in our process:

• Advanced Check: Probe directly on a CNC computer and perform the final inspection based on your GD&T requirements using high-precision CMM (coordinate measuring machine), optical comparator and surface roughness tester.
• Process control: Strict process planning, simulation software verification, skilled mechanics and certified quality systems.
• Material Certification: Certificate of traceable materials provided upon request.
• experience: We always deal with the most stressful tolerances required for aerospace and medical applications. example: Hold tolerances within ±0.0005" (±0.0127mm) or tighter when needed. Please contact the engineer to discuss your specific requirements.
