cnc thread milling Reference Specifications (varies for different product)
Thread milling is a versatile, cost-effective process for anyone needing to create threads in the axial direction of a part. It involves a cutting tool that creates threads in a pre-drilled hole. Here are some reference specifications for CNC thread milling:
1. Tool Material: The tool material can be high-speed steel (HSS), carbide, or cobalt. The choice depends on the hardness of the material being milled.
2. Tool Diameter: The diameter of the tool should be less than the diameter of the hole. This allows the tool to move freely within the hole and create the thread.
3. Thread Size: The thread size is determined by the pitch (distance between threads) and the diameter of the hole. Common thread sizes include metric (M), unified national coarse (UNC), and unified national fine (UNF).
4. Thread Direction: Threads can be right-hand (clockwise rotation) or left-hand (counter-clockwise rotation). The direction is chosen based on the application.
5. Cutting Speed: The cutting speed is determined by the material being milled and the tool material. Harder materials require slower speeds, while softer materials can be milled at higher speeds.
6. Feed Rate: The feed rate is the speed at which the tool moves through the material. It is typically measured in inches per minute (IPM) or millimeters per minute (mm/min).
7. Coolant: Coolant is often used in thread milling to reduce heat and prolong tool life. It can be a liquid or gas, such as compressed air.
8. Machine Type: Thread milling can be done on a variety of CNC machines, including milling machines, lathes, and machining centers.
9. Software: The CNC machine is controlled by software that translates the design into instructions for the machine. The software also controls the speed, feed rate, and other parameters.
10. Tolerance: The tolerance is the allowable deviation from the specified dimensions. It is typically expressed as a plus or minus value.
These specifications can vary depending on the specific product and application. Always consult with the tool manufacturer or a machining specialist for the best results.
