Great Magtech (Xiamen) Electric Co., Ltd is one of the most reliable manufacturers and suppliers of ground thread turning inserts in China. We warmly wlecome you to buy high quality ground thread turning inserts from our factory. Contact us for more details.
ground thread turning inserts Description
Our ground thread turning inserts represent the pinnacle of precision machining, engineered for applications where exceptional surface finish and absolute dimensional accuracy are non-negotiable. Unlike standard inserts, these are meticulously crafted through a specialized grinding process post-sintering, which ensures ultra-precise geometry, razor-sharp cutting edges, and flawless thread profiles. This meticulous manufacturing minimizes micro-chipping and guarantees consistent, high-quality performance in the most demanding threading operations, making them the ideal choice for producing clean, perfect threads in a single pass.
ground lathe threading inserts Features

● A large chip reversal angle and chip flute design effectively curl chips and facilitate smoother chip evacuation.
● Precision-ground, wide, flat cutting edges ensure sharp cutting.
● Precision-ground tooth profiles guarantee dimensional accuracy of E-grade ±0.025mm.
● Precision-ground finishing arcs ensure a smooth surface finish.
● Available in sizes 08, 11, 16, 22, and 27.
Comparison of cutting life of competitors
According to the latest performance test data, GME brand high-precision thread turning tools excel in the key indicator of tool life, with an average processing life of 23 pieces/piece, significantly exceeding competitor A by more than 20%, demonstrating longer-lasting wear resistance and stable processing performance. The specific comparison is shown in the figure below:

Application of ground thread turning inserts
Grinding type thread turning blades have rich tooth profile standards, high-precision tooth profile dimensions, and stable edge treatment, which can process various high-precision threads and achieve high surface smoothness; By combining multiple grades to flexibly cope with the working conditions of various processing materials such as P/M/K, it can meet the high-precision thread processing requirements in fields such as oil and gas, food and fire protection, and machine tool industry.
