When it comes to precision manufacturing, you’ll often encounter two crucial processes\u2500 CNC milling and CNC turning. Knowing the variations among these methods can assist you to optimize production, make better quality products and decrease cost. So let\u2019s explore how these two techniques are different.<\/p>\n\n\n\n

What is CNC Milling?<\/h2>\n\n\n\n
\"CNC<\/figure>\n\n\n\n

In CNC milling<\/a>, you will use computer controlled tools to cut or shape material on a fixed workpiece. Shaping the material is usually made with a cutting tool which is spinning at high speed along many axes (X, Y, and Z) to cut the material. This is a very handy method to generate intricate parts, flat surfaces and angular cuts. CNC milling can be applied to a broad variety of materials from metals to composites to plastics.<\/p>\n\n\n\n

What is CNC Turning?<\/h2>\n\n\n\n
\"What<\/figure>\n\n\n\n

On the other hand, in CNC turning<\/a>, a workpiece is rotated and cutting tool is stationary. Such a process is perfect for producing round or symmetrical components such as shafts, pins and bolts. In this process the workpiece is spun on a lathe and material is removed by a computer controlled cutting tool. This is a high efficiency, high precision method and it works with different materials such as metals, plastics, etc.<\/p>\n\n\n\n

Main Differences Between CNC Milling and CNC Turning<\/h2>\n\n\n\n
\"Main<\/figure>\n\n\n\n

1. Working Process<\/h3>\n\n\n\n

CNC milling is a way of material removal which uses a spinning cutting tool to remove material out of a stationary workpiece. During milling, the machine\u2019s spindle, which holds the tool, moves on multiple axes to make complicated shapes. Due to this versatility, different features, such as contour, flat surface and pocket can be produced.<\/p>\n\n\n\n

Whereas CNC turning has a workpiece that rotates and a cutting tool that does not. Workpiece is clamped in a chuck on a lathe<\/u><\/a> and spun at fast speed. The cutting tool shapes the workpiece to required shape by moving along the depth and length of workpiece.<\/p>\n\n\n\n

2. Tool Movement and Operation<\/h3>\n\n\n\n

Cutting tool moves in three axes (X, Y and Z) at fast speed in milling. With this multi axis movement you can create complex features and shapes. Depending on the operation, end mills, drills, face mills and other such tools are used in milling.<\/p>\n\n\n\n

Operation of turning is characterized by linear movement of a tool along the diameter of the rotating workpiece. The cutting tool will most usually be a single point cutting tool, i.e. a lathe tool, which removes material by continuous rotation. This is a particularly good setup to make symmetrical and cylindrical parts.<\/p>\n\n\n\n

3. Types of Parts Produced<\/h3>\n\n\n\n

CNC milling is a great way to create parts that have non rotational features and complicated geometries. It\u2019s an ideal way to make components with complicated features, uneven shapes and flat faces. Milled parts\u2019 examples are engine blocks, aerospace parts and customized furniture parts.<\/p>\n\n\n\n

CNC turning, however, focuses on axially symmetrical and cylindrical parts. It is perfect for manufacturing components such as rods, shafts and pins where the part geometry is around a single axis. Other turning operations including taper turning<\/u><\/a>\u00a0and threading allow you to create features, like grooves, tapers and threads into cylindrical workpieces.<\/p>\n\n\n\n

4. Surface Finish and Tolerances<\/h3>\n\n\n\n

Milling give extraordinary surface finishes<\/a> for complex or flat nonrotational parts. You can achieve very strict tolerances \u2014 in the \u00b10.005 inches range and even better. That\u2019s why It\u2019s suitable for applications that need very smooth finishes and greater precision on complicated geometries.<\/p>\n\n\n\n

Turning also creates superior surface finishes but is only possible for cylindrical parts, which is because of the continuous rotation of work piece. It offers high accuracy of concentricity and diameter, thus suitable to make rods, shafts and other round parts that need good accuracy<\/p>\n\n\n\n

5. Speed and Precision<\/h3>\n\n\n\n

Milling machines provide high precision to an accuracy of microns. That\u2019s why they are important for industries such as electronics and aerospace in which precision is a must. But the complicated nature of parts produced by milling makes it slightly slower than turning.<\/p>\n\n\n\n

In general, CNC turning is faster than milling in the making of symmetrical parts. It’s great at producing greatly accurate cylindrical components but it can\u2019t compete with milling when it comes to intricate design. Similar to milling, turning can also achieve tolerances around \u00b10.005 inches.<\/p>\n\n\n\n

Applications of CNC Turning and CNC Milling<\/h2>\n\n\n\n

CNC milling and turning are both important in many fields. Distinct applications for these machining processes are based on the special capabilities of these machining processes.<\/p>\n\n\n\n
