What are the tools used for parting off on a lathe machine?
When it comes to machining operations on a lathe machine, parting off is a crucial process. Parting off, also known as cutoff, is the operation of separating a workpiece into two parts by cutting through it. This is often required when producing multiple parts from a single bar stock or when removing excess material from the end of a workpiece. In this blog, as a lathe machine supplier, I will introduce the various tools used for parting off on a lathe machine.
Parting Off Blades
Parting off blades are the most common tools used for parting off operations. These blades are typically made of high - speed steel (HSS), carbide, or ceramic materials. High - speed steel blades are cost - effective and suitable for general - purpose parting off on a variety of materials, including mild steel, aluminum, and brass. They can withstand relatively high cutting speeds and have good toughness, which helps prevent the blade from chipping during the cutting process.
Carbide parting off blades, on the other hand, offer superior performance in terms of wear resistance and cutting speed. They are ideal for parting off hard materials such as stainless steel, alloy steels, and cast iron. Carbide blades can maintain their sharpness for a longer period, reducing the frequency of blade replacement and improving overall productivity. Ceramic parting off blades are even more wear - resistant than carbide blades, but they are also more brittle. They are mainly used for high - speed parting off of extremely hard materials in precision machining applications.
When selecting a parting off blade, factors such as the material of the workpiece, the required cutting speed, and the depth of cut need to be considered. The width of the blade is also an important parameter. A wider blade is more suitable for parting off larger workpieces, while a narrower blade can be used for more precise and intricate parting off operations.
Parting Off Tools with Inserts
Parting off tools with inserts are another popular choice. These tools consist of a tool holder and replaceable inserts. The inserts are made of carbide or other advanced cutting materials. The advantage of using tools with inserts is that when the cutting edge of the insert becomes worn, only the insert needs to be replaced, rather than the entire tool. This not only reduces the cost of tool replacement but also saves time.
Inserts come in different geometries, such as square, triangular, and round. Each geometry is designed for specific cutting applications. For example, square inserts are suitable for general - purpose parting off, while triangular inserts can provide better chip control in certain situations. The cutting edge of the insert can also be customized with different coatings to improve its performance, such as titanium nitride (TiN) coating for enhanced wear resistance.
Grooving and Parting Off Toolholders
Toolholders play a vital role in holding the parting off blades or inserts securely in place during the cutting process. There are various types of grooving and parting off toolholders available in the market.
One common type is the external parting off toolholder, which is used for parting off the outside diameter of a workpiece. These toolholders are typically mounted on the tool post of the lathe machine and can be adjusted to different angles and positions to achieve the desired cutting effect. Internal parting off toolholders, on the other hand, are used for parting off the inside diameter of a workpiece, such as in the machining of pipes or tubes.
Some toolholders are designed with special features to improve chip evacuation. For example, they may have built - in channels or grooves that help direct the chips away from the cutting area, preventing chip jamming and improving the surface finish of the workpiece.
Formed Parting Off Tools
Formed parting off tools are customized tools designed to create specific shapes during the parting off process. These tools are often used in applications where a non - standard shape is required at the parting off point. For example, in the production of automotive components or aerospace parts, formed parting off tools can be used to create complex profiles on the workpiece.
Formed parting off tools are usually made by grinding or machining a solid piece of tool material to the desired shape. They require high - precision manufacturing processes to ensure accurate cutting. These tools are more expensive than standard parting off tools, but they can significantly improve the quality and functionality of the final product.
