CNC Machined Components

What Are CNC Sintered Machined Components?

CNC sintered machined components are manufactured using a two-step process that combines the efficiency of Powder Metallurgy (PM) with the precision of Computer Numerical Control (CNC) machining.

1. Powder Metallurgy (PM) is used to form near-net-shape metal parts through high-pressure compaction and sintering.
   
2. CNC machining is then applied to enhance dimensional accuracy, create intricate features, and meet critical performance tolerances.
   

This hybrid approach provides the perfect balance of cost-effectiveness and high precision—ideal for industries requiring robust, high-performance components produced at scale.

Our CNC Machining and Secondary Capabilities

Atlantic Sintered operates a fully integrated CNC machining department within our Massachusetts facility. Our machining capabilities support both high-volume production and low-volume specialty orders, with a focus on speed, consistency, and precision.

Our CNC Machining Services Include:

• Turning & Manufacturing Cells – Ideal for round and cylindrical parts with tight tolerances
  
• Hard Turning – Machining sintered parts after heat treatment or for hardened surfaces
  
• Facing – Creating flat surfaces and clean faces for proper part mating
  
• Milling – Multi-axis capability to machine complex shapes, slots, and contours
  
• Drilling & Tapping – Precision holemaking and threading for fasteners and fittings
  
• Boring – Enlarging and refining internal diameters
  
• Grinding & Centerless Grinding – Achieving ultra-smooth finishes and precise OD dimensions
  
• Honing – Enhancing internal bore finishes and roundness for wear-critical applications
  
• Threading – Internal and external threading for mechanical compatibility
  
• Welding – Structural joining and reinforcement of multi-part assemblies
  

Each operation is performed with modern CNC equipment and handled by experienced technicians who specialize in machining powdered metal components.

Why Choose CNC Machined Powdered Metal Components?

Powder Metallurgy offers an efficient way to produce high-strength parts with minimal waste. However, sintered components alone may not always meet every functional or dimensional requirement. That’s where CNC machining adds value.

Benefits of CNC Sintered Machined Components:

• Tight Tolerances – Machining ensures precision fit for assemblies and mating parts
  
• Complex Features – Threads, bores, undercuts, and slots can be machined with high accuracy
  
• Improved Surface Finish – Ideal for sealing surfaces, wear interfaces, and aesthetic applications
  
• Higher Strength & Density – Machining post-sintering improves edge quality and overall performance
  
• Cost-Effective Production – Combines the efficiency of PM with selective machining only where needed
  
  

With Atlantic Sintered, you get the best of both worlds—cost-effective production and custom-tailored precision machining, all under one roof.
