Thread Cutting

Generally refers to the method of processing threads on the workpiece using forming tools or grinding tools, mainly including turning, milling, tapping, threading, grinding, grinding and whirlwind cutting.

Thread Milling

Milling is performed on a thread milling machine with a disc or comb cutter. Disc milling cutters are mainly used for milling trapezoidal external threads on screw rods, worms and other workpieces.

Thread Grinding

Mainly used for processing precision threads of hardened workpieces on thread grinders. According to the different cross-sectional shapes of the grinding wheels, there are two types of grinding: single-line grinding wheels and multi-line grinding wheels.

Thread Grinding

Nut-type or screw-type thread grinding tools are made of soft materials such as cast iron, and the parts of the processed threads on the workpiece that have pitch errors are ground in forward and reverse rotation to improve the pitch accuracy. Hardened internal threads are usually ground to eliminate deformation and improve accuracy.

Tapping and Threading

Tapping is to use a certain torque to screw a tap into a pre-drilled bottom hole on the workpiece to process an internal thread. Threading is to use a die to cut external threads on the bar (or pipe) workpiece. The processing accuracy of tapping or threading depends on the accuracy of the tap or die. Although there are many methods for processing internal and external threads, small-diameter internal threads can only be processed with taps. Tapping and threading can be done manually, or lathes, drill presses, tapping machines and threading machines can be used.
