In the rolling of bars and wires, high-speed steel (HSS) rolls are becoming an important choice for steel mills due to their excellent wear resistance, high-temperature red hardness, and thermal fatigue resistance.
But it also brings a problem – difficult to process!
Why are high-speed steel rolls difficult to process?
High-speed steel rolls have high hardness (HRC63 or above), contain a large amount of high-hardness carbides, and are cast by centrifugal casting. The hardness distribution of the blanks is uneven, often accompanied by problems such as inclusions, ladle sand, and cold-hardened layers. During processing, the cutting tools are prone to damage, chipping, excessive vibration, high cutting temperature, low processing efficiency, and even affect the service life of the equipment.
Common challenges include:
The rough machining allowance is large, there are many casting defects, and the cutting impact is large.
There are many hard spots, deep, cold, and hard layers, and the cutting tools are severely worn.
Frequent vibration, high risk of chipping, and difficult control of surface quality.
Our solution: Designed for difficult-to-process materials
Facing the extreme materials of HRC65 to 70, we have integrated advanced tool materials, specialized machine tools and equipment, and a reasonable process layout, successfully overcoming the processing difficulties of HSS rolls!
Professional equipment support
The CNC roll lathe (CK8450) is precise and efficient, supporting the processing of complex curves
Special forming tools, in combination with intelligent programs, achieve efficient batch slotting
High-performance tool system
We design PCBN tools with high hardness and wear resistance for high-temperature and high-intensity cutting.
Combining strength and toughness, it effectively prevents chipping and extends service life.
We selected the most suitable main deflection angle and blade shape through experimental comparison to optimize the cutting contact surface.
Practical process strategy:
Our operators use large feed and deep cuts to eliminate the cold-hardened layer during rough turning.
Choose a combination of circular and square blades to achieve a balance between strength and heat dissipation.
The concept of high-speed cutting enhances efficiency while extending tool life.
