Machining with chip removal is the process of manufacturing mechanical products by removing material from the initial workpiece. This is a crucial step in creating machine parts with high precision. In this article, let's explore with Truong Thinh Mechanical the concept of a workpiece, types of materials, common machining methods, and a trusted machining provider.

What is a Workpiece in Machining?

In the field of machining with chip removal, a workpiece refers to the input material used to create the finished product. It can be large metal sheets, raw blocks of material, or semi-finished products just removed from casting molds. During machining, workers use machines such as lathes or milling machines to cut, shape, and form the workpiece into a design based on technical drawings.

A simple example: to produce a steel bed frame, workers start with raw steel bars – this is the workpiece. From there, they cut, weld, and assemble the parts into a complete product.

Not limited to metal sheets, in chip removal machining, workpieces can also include post-casting products such as: cast gear blanks, flange workpieces, bronze bearing blanks… These are unprocessed surfaces that need further turning, grinding, and finishing to meet high precision standards.

Materials Used in Machining with Chip Removal

Depending on the usage purpose and technical requirements, materials used for machining are quite diverse, divided into two main groups: metallic and non-metallic materials.

Metallic Materials and Alloys

This is the most commonly used group in chip removal machining:

• Steel: SS400, S45C, SKD11, SKD61...

• Stainless Steel (Inox): SUS201, SUS304, SUS316

• Cast Iron: Grey cast iron, ductile iron, white iron

• Aluminum: A7075, A5052, A6061

• Copper: C3601, C3602, C9500

• Others: Iron, zinc, tin, etc.

Choosing the right material affects the durability, load-bearing ability, and precision of the final product.

Non-Metallic Materials

Although less common, non-metallic materials are used in some specialized products such as:

• Industrial wood

• Technical plastics: PVC, PP, PE, PMMA

• Acrylic (Mica)

Common Machining Methods with Chip Removal

Chip removal machining uses various machines to remove excess material from the workpiece to form product details. Some typical methods include:

Lathe Machining

Turning is the most common method in chip removal. The workpiece rotates while the cutting tool remains stationary to remove material in cylindrical or conical shapes.

Milling

Milling uses a rotating cutter to cut away material. This method is suitable for flat surfaces, slots, or complex multi-axis shapes.

Planing and Grinding

Planing creates flat surfaces, while grinding ensures high precision and surface finish. These are important final steps in machining.

Finishing Operations

After basic shaping, the product undergoes final finishing to ensure dimensions and surface smoothness meet exact standards.
