Turning is a method of cutting a workpiece on a lathe by rotating the workpiece relative to the tool. Turning is the most basic and common cutting method. Most workpieces with the rotary surface can be processed by turning methods, such as inner and outer cylindrical surfaces, inner and outer conical surfaces, end faces, grooves, thread, and rotary forming surface. Common lathes can be divided into horizontal lathes, ground lathes, vertical lathes, turret lathes, and imitation lathes, most of which are horizontal lathes.
Our cnc precision turning parts for hardened steel combine rigid CNC lathe stability, optimized cutting parameters and advanced tool choices (coated carbide, ceramic and cubic boron nitride) to deliver high dimensional accuracy, superior surface quality and consistent roundness. Hard turning provides higher material removal rates and lower equipment and auxiliary costs than grinding, enabling efficient, cost-effective small-batch production with excellent positional accuracy between machining surfaces and minimal risk of surface burns. By rotating the workpiece and performing single-clamp multi-surface operations, the turning structure enables machining of inner/outer cylindrical and conical surfaces, faces, grooves and threads in one setup, ensuring repeatable tolerances and robust surface integrity for hardened steel components.
Our engineering and production team blends decades of precision machining experience with specialized hard-turning expertise for hardened steel. Core strengths include senior CNC programmers, veteran toolmakers, metallurgists, and quality engineers who optimize processes for repeatable tight tolerances and surface integrity. Value-driven capabilities include fast prototyping, customized tooling design, robust in-line inspection (CMM, roundness, hardness testing), and continuous improvement practices that reduce lead times and scrap. Cross-functional collaboration ensures clear communication, responsive engineering changes, and reliable delivery. We support scalable volumes while maintaining strict quality standards, providing customers consistent performance, cost-efficiency, and confidence in demanding applications and warranty-backed after-sales support guaranteed.

Common lathes can be divided into horizontal lathes, ground lathes, vertical lathes, turret lathes, and imitation lathes, most of which are horizontal lathes.
Due to the development of modern science and technology, a variety of high strength, high hardness engineering materials are more and more used, the traditional turning technology is not competent or can not realize the processing of some high strength, high hardness materials, but the modern hard turning technology makes it possible and in the production of obvious benefits.
(1) High turning processing efficiency
Turning has higher efficiency than grinding. Turning often uses large cutting depth, and high workpiece speed and its metal removal rate is usually several times that of grinding. A variety of surfaces can be finished by clamping at one time in turning, while many installation times are needed in grinding, so the auxiliary time is short and the position precision between the machining surfaces is high.
(2) Low cost of equipment input in the productivity of the same lathe investment is significantly better than the grinding machine, its auxiliary system cost is also low. For small batch production, turning does not require special equipment, while large batch processing of high precision parts requires good rigidity, positioning accuracy, and repeated positioning accuracy of CNC machine tools.
(3) suitable for small batch flexible production requirements lathe itself is a flexible processing method with a wide range of processing, lathe control is simple and fast turning clamping, compared with grinding hard turning can better adapt to flexible production requirements.
(4) Hard turning can make the parts get good overall machining accuracy
Most of the heat produced in hard turning is taken away by the cutting oil, which will not produce surface burns and cracks like grinding processing. It has excellent machining surface quality, and accurate machining roundness, and can ensure high position accuracy between machining surfaces.
(1) coated carbide cutting tool
The coated cemented carbide tool is coated with a layer or multilayer coating with good wear resistance on the carbide tool with good toughness. The coating usually plays the following two roles: on the one hand, it has much lower thermal conductivity than the tool matrix and the workpiece material, which weakens the thermal effect of the tool matrix; On the other hand, it can effectively improve the friction and adhesion of cutting process and reduce the generation of cutting heat. Compared with cemented carbide tools, coated carbide tools have been greatly improved in strength, hardness, and wear resistance.
(2) ceramic material tool
Ceramic cutting tools have the characteristics of high hardness, high strength, good wear resistance, good chemical stability, good bond resistance, low friction coefficient, and low price. When used normally, the durability is very high, the speed is several times higher than that of cemented carbide, especially suitable for high hardness material processing, finishing processing, and high-speed processing.
(3) cubic boron nitride cutting tool
The hardness and wear resistance of cubic boron nitride are second only to diamond, and it has excellent high-temperature hardness. Compared with ceramic cutting tools, its heat resistance and chemical stability are slightly worse, but its impact strength and crushing resistance are better. It is widely used in the machining of hardened steel, pearLItic gray cast iron, chilled cast iron, high-temperature alloy, etc. Compared with a cemented carbide tool, its cutting speed can even be increased by one order of magnitude.
