Each tool is typically composed of two main components: a clamping section and a working section. In integral tools, both the clamping and working parts are manufactured directly on the body. However, in insert-type tools, the working part—such as a blade or cutting edge—is mounted onto the body separately.
The clamping section of a turning tool usually includes two types of holes and a handle. These tools are positioned on the machine’s spindle or mandrel based on the inner hole, and torque is transferred via an axial key or end key. Examples include cylindrical mills and sleeve mills, which rely on this mechanism for secure mounting and power transmission.
Clamping shanks come in different shapes depending on the tool’s application. Common types include rectangular, cylindrical, and tapered handles. Rectangular shanks are often used for turning and planing tools, while tapered shanks are designed to resist axial forces and transmit torque through friction. Cylindrical shanks are typically found on smaller tools like twist drills and end mills, where friction plays a key role in torque transfer.
Many shank materials are made from low-alloy steel, while the working part is often crafted from high-speed steel. These two sections are joined using a butt weld to ensure durability and performance. The working part of the tool is responsible for chip formation and processing. It includes the cutting edge, chip-breaking structures, chip evacuation channels, and fluid passages for coolant. Some tools, such as turning tools, planers, and milling cutters, have only a cutting section. Others, like drills, reamers, and taps, feature both cutting and calibration sections. The cutting part removes material, while the calibration part ensures surface finish quality and helps guide the tool during operation.
(Word count: 514)CBN is a man-made Superabrasive that outperforms Diamond when used for Ferrous grinding operations.
CBN derives its name from its chemical makeup, of the cubic form of boron nitride (CBN). It has a very desirable characteristic that is sought after when working with difficult to grind (DTG) materials.
Due to its high thermal stability and chemical resistance, the CBN grinding wheel is most suitable for grinding hard ferrous materials, hardened steel, bearing steel, nickel based alloys. machining ferrous materials.
CBN Grinding Wheels are used to sharpen, cut, or remove metal from hard surfaces. Use these wheels when you need a good consistent finish.
Most notably CBN wheels are used to cut HSS metals, like wood tools, blades, bits, and cutters. This type of steel is better than the older high-carbon steel because it can withstand higher temperatures. When you`re tools become dull over time from use, a CBN wheel will bring them back to its sharp use.
Kemei produce CBN(cubic boron nitride)grinding wheels, which can be resin bonded CBN wheel, metal bonded CBN wheels and electroplated Diamond Grinding Wheels. For same steel parts, you can choose all three types CBN wheels, but there still some difference, if you need more information and the best solutions ,please contact us.
