Passivation of Stainless Steel: Process, Methods, & Industry Applications
Machining, welding, and forming processes create free iron particles or metal contaminants on the surface of stainless steel, preventing it from having its full natural corrosion resistance. Stainless steel has a thin layer of ...
Anodizing vs Electroplating: Differences, Benefits & How to Choose the Right Finish
Anodizing and electroplating are two common surface finishing processes used to improve metal parts. Although both involve an electrical process, they produce very different surface characteristics. Anodizing converts the outer...
PVD Coating (Physical Vapor Deposition): Process, Types, Materials & Benefits
PVD (Physical Vapor Deposition) coating is one of today’s finest surface treatment technologies and is very adaptable to many of industrial manufacturing processes. Moreover, with recent industrial demands for coatings th...
CNC Surface Grinding: Process, Types, Applications & Precision Control
Surface grinding in CNC is usually performed after milling. For example, it is done when the part still does not sit flat during inspection. You may machine a plate, measure it, and still see light gaps on a surface plate or un...
Centerless Grinding: How It Works, Types, Advantages & Applications
Centerless Grinding is a type of precise cylindrical grinding that takes material off the outside diameter of a rotating workpiece without being mounted between centers or clamped in a chuck. Rather than that, the workpiece ac...
What is Thread Milling: Process, Techniques & Useful Tips
Thread milling is a precise CNC process used to create internal and external threads in metals and engineering plastics. A rotating multi-flute cutter moves along a helical path, gradually removing material instead of forcing a...
Blind Hole in Engineering: Types, Design Considerations & Machining Guide
Blind holes are precision-machined cavities that penetrate a workpiece to a specified depth. However, they do not go through and will therefore have a closed bottom. To distinguish from through holes, blind holes will have impo...
Snap Fit Joint Design: Types, Materials, Engineering Guidelines & Practices
The design of snap-fit joints significantly affects the performance of a product and its associated cost to manufacture. Unlike other fasteners, such as screws or glue, snap-fit joints depend on elastic deformation, which is th...
Perpendicularity in GD&T: Definition, Types, Tolerance & Measurement
In CNC machining, achieving an exact 90-degree relationship between features is a measurable, controllable, and inspectable requirement. Whether it is a flange face produced by milling, a bearing bore generated with a boring cy...
CNC Machining Tolerances: Types, Standards, and Selection Guide
CNC machining can produce highly accurate parts, but dimensional variation still happens during manufacturing. Tool wear, material behavior, machine condition, and inspection methods all affect the final result. Even a small di...
