Lastuamistyökaluja

Lastuamistyökaluja, or chip-forming tools, are a category of cutting tools used in machining operations to remove material from a workpiece in the form of chips. The primary function of these tools is to shape and dimension materials through a process of material detachment. Common examples of lastuamistyökaluja include drills, milling cutters, lathes, and broaches, each designed for specific cutting actions and workpiece geometries.

The effectiveness of lastuamistyökaluja relies on several factors, including the tool's material composition, its geometric design, and the machining parameters employed. Tool materials typically include high-speed steel (HSS), cemented carbides, ceramics, and cubic boron nitride (CBN), chosen for their hardness, wear resistance, and ability to withstand high temperatures generated during cutting. The geometry of the tool, such as rake angles, clearance angles, and the presence of cutting edges, dictates the chip formation process, surface finish, and cutting forces.

Machining operations utilizing lastuamistyökaluja range from simple drilling to complex milling and turning. The choice of tool and its application are critical for achieving desired workpiece specifications, such as dimensional accuracy, surface quality, and geometric form. Proper maintenance, including sharpening and inspection, is essential to ensure optimal performance and longevity of these tools.
