Computer Numerical Control (CNC) turning tools play a crucial role in modern-day manufacturing processes. Utilized in various industries such as aerospace, automotive, and electronics, these advanced tools ensure the production of precise, high-quality parts. This article aims to explore the different CNC turning tool names, their unique characteristics, and a variety of applications they satisfy.
The World of CNC Turning Tools
CNC turning is a subtractive manufacturing process that involves removing material from a workpiece using computer-driven cutting tools. Since turning involves different types of operations, such as face turning, contouring, and drilling, a diverse range of cutting tools is required to accommodate these tasks. Let's look at some of these essential CNC turning tools.
Inserts
Inserts are the cutting part of a tool holder, usually replaceable to ensure the continuity of a machining process without significantly interrupting production. They come in various shapes, materials, and coatings aimed at specific applications. Common materials for inserts include carbide, ceramics, and polycrystalline diamond (PCD), each with their own advantages.
1. Carbide Inserts- These are the most widely used in the manufacturing industry due to their high wear resistance, high cutting speeds, and significant edge retention.
2. Ceramic Inserts- These inserts offer elevated cutting speeds and increased thermal stability, ideal for cutting hardened materials and surface finishing.
3. Polycrystalline Diamond (PCD) Inserts- Utilized in cutting non-ferrous metals, PCD inserts feature exceptional hardness and wear resistance, ensuring a longer tool life.
Tool Holders
Tool holders are designed to house inserts securely, allowing them to access the workpiece during a cutting operation. Some common tool holders include:
1. External Turning Tool Holders- These holders are employed for turning or facing operations on the external surface of a workpiece. They come in multiple shapes and sizes, accommodating various insert types.
2. Boring Bars- Boring bars are long, cylindrical tool holders that house inserts intended to enlarge or amend existing holes in workpieces. Bores created with these tools can have precise diameters and smooth internal surfaces.
3. Drill Holders- These tool holders contain twist drills or solid carbide drills to provide various hole-making operations such as drilling, reaming, and tapping.
Grooving and Parting Tools
Grooving and parting tools are essential for separating parts or generating recessed patterns on a component. Some standard grooving and parting tools include:
1. Straight Grooving Tools- These straight-edged tools create precise cuts, often used for O-ring housings, snap rings, and other recessed features.
2. Full Radius Grooving Tools- Equipped with a curved edge, these tools cut a complete circular arc to provide accurate and smooth grooves.
3. Cut-Off or Parting Tools- As the name suggests, these tools are utilized to cut off sections of a workpiece, often to separate a finished product from the remaining material.
Threading Tools
An essential component within many industries, threading tools create screw threads on workpieces. These tools include:
1. External Threading Tools- Designed to cut threads on the outer surface of a workpiece, these tools encompass single-point thread milling cutters and multi-point taps.
2. Internal Threading Tools- Typically employing taps or thread milling cutters, internal threading tools cut internal screw threads into components.
CNC Turning Tool Applications
With a solid understanding of the types of CNC turning tools, let's explore various applications.
1. Aerospace- CNC turning tools create intricate and high-quality components, solidifying their spot in aerospace operations. Parts crafted with turning tools can be found within jet engines, aircraft landing gears, and hydraulic systems.
2. Automotive- Numerous automotive components require precise manufacturing, making turning tools invaluable for creating gears, shafts, and bearings. External threading tools specifically lead the creation of engine cylinder heads, wheel hubs, and spindle nuts.
3. Electronics- CNC turning plays a significant role in producing electronic connectors, heat sinks, precision pins, and other components that guarantee smooth functioning.
This article provides a comprehensive description of various CNC turning tools and their applications. Equipped with this knowledge, you are now prepared to identify the perfect tool for your manufacturing needs.
