PEEK CNC Machining: Properties, Applications, and Machining Guidelines

PEEK (Polyether Ether Ketone) is a high-performance engineering plastic that is often used as a substitute for metals in CNC machining. The strength of PEEK is comparable to aluminum alloys and some stainless steels, and its weight is half that of aluminum, which has important value in lightweight design. PEEK can maintain stable performance at …

Is 1018 Steel Good for CNC Machining?

1018 steel is one of the most common low-carbon steels used in CNC machining. It offers excellent machinability, stable cutting behavior, and low cost, making it ideal for shafts, pins, brackets, and general-purpose components. In the cold-drawn condition, 1018 typically has a tensile strength of ~440 MPa, yield strength ~370 MPa, and a machinability rating …

What Are the Properties and Applications of 4140 Steel?

4140 steel is a chromium-molybdenum alloy steel widely used in automotive, aerospace, oil and gas, and heavy machinery. Its balance of tensile strength, toughness, and machinability makes it one of the most versatile engineering steels.

With proper heat treatment, 4140 provides reliable performance in demanding applications such as gears, shafts, and high-strength fasteners.

Cast Aluminum and Aluminum Casting: A Guide You Need to Know

Aluminum, as a lightweight metal, is widely used thanks to its low density, corrosion resistance, and excellent thermal conductivity. In automotive lightweighting, aerospace, machinery manufacturing, and consumer products, cast aluminum and aluminum casting processes play a crucial role. From large engine housings to everyday furniture and cookware, cast aluminum parts have become an essential component …

Black Oxide Coating in Metal Surface Treatment

Black oxide coating is a widely used finishing process in metal manufacturing. Instead of adding an external layer such as paint or plating, it chemically converts the surface of the base metal into a thin, stable black oxide film. This finish is valued for its uniform dark appearance, dimensional stability, and cost efficiency.

The process …

Transparent vs Translucent vs Opaque Materials: Choosing the Right Components, Methods, and Projects

In manufacturing, the way a material interacts with light is more than an aesthetic detail—it often dictates design feasibility and production methods. Engineers choosing between transparent, translucent, and opaque materials are not simply deciding how a product will look. They are defining performance in optical clarity, light diffusion, or complete light blocking. These properties determine …

Metal Strength: Tensile Strength, Hardness, and Real-World Applications

In precision machining, understanding the strength of metals is essential for both design and production. Tensile strength, yield strength, compressive strength, and hardness not only determine how a material performs in service but also influence how the material can be cut, milled, drilled, or finished. High-strength steels demand different tool geometries and cutting speeds compared …

PVC Plastic (Polyvinyl Chloride): Properties, Types, and Applications

Polyvinyl chloride (PVC) is one of the world’s most widely used thermoplastics, accounting for nearly 20% of global polymer demand. PVC plastic offers a balance of strength, flame resistance, chemical durability, and affordability, which explains its use in construction, healthcare, electrical systems, and consumer goods. The adaptability of PVC comes from its ability to be …

Different Types of Bearings and Their Characteristics

Bearings are essential machine components that support shafts, reduce friction, and make rotational or linear motion smoother and more reliable. Bearings can be found in almost every kind of equipment, from small household devices to large industrial machinery. Each type of bearing has unique design features that make the component suitable for specific loads, speeds, …

Why does metal galling occur and how can it be prevented?

In many mechanical systems, engineers face the challenge of metal parts seizing or locking together during service. This sudden failure is not caused by fracture or corrosion but by a specific adhesive wear phenomenon known as galling. Galling has been reported in industries from aerospace fasteners to oilfield bearings, leading to expensive downtime and component …
