Which Brand Of Difficult-to-process Stainless Steel Blades in China Has The Best Service

Kunshan Meiyaxing Hardware Machinery Co., Ltd. is a direct branch of Hong Kong Meiya International Trading Company in China. It has its own tool brand: MANF, engaged in CNC tool sales and operation services. Provide tungsten steel milling cutters, milling blades, turning blades, grooving and cutting blades, drilling and boring blades, multi-functional blades, threading blades and other indexable blades and their matching tool holders and cutter discs. And reached long-term strategic cooperation with many well-known production factories. The two sides jointly developed, designed, and produced teams, advanced equipment, and continuously innovative technical strength. They are committed to mutual cooperation, guided by technical services, and formed a form of mutual reliance in the industrial chain to solve various processing problems for processing and manufacturing companies.
Difficult-to-process stainless steel (such as X91CrMoV18, duplex stainless steel, etc.) has high hardness, toughness and cold hardening tendency, which puts extremely high demands on tools during the cutting process. This article combines material properties, tool selection and processing technology to systematically analyze the blade selection strategy and technical advantages suitable for such materials.
II. Selection and advantages of blade materials
1. Cemented carbide (YG type)
- Advantages: High toughness, strong impact resistance, suitable for rough machining and intermittent cutting. YG cemented carbide has excellent thermal conductivity, which can effectively disperse cutting heat and reduce thermal cracks.
- Applicable scenarios: Recommended for rough turning tools, cut-off tools and reaming drills, especially suitable for rough machining of duplex stainless steel.
2. Coated cemented carbide (such as TiAlN coating)
- Advantages: TiAlN coating is resistant to high temperatures (up to 900°C), reduces friction coefficient and prolongs tool life. Kennametal's patented coating technology can improve the stability of tools at high temperatures.
- Applicable scenarios: Finishing and high-speed cutting, such as machining high-hardness stainless steel such as X91CrMoV18.
3. Cubic boron nitride (CBN)
- Advantages: Superhard material (hardness second only to diamond), excellent high-temperature resistance, suitable for finishing hardened stainless steel (hardness ≥55HRC).
- Applicable scenarios: High-precision grinding or finishing processes, such as the final forming of medical device cutting tools.
4. High-performance high-speed steel (such as tungsten-molybdenum system)**
- Advantages: Good toughness, can manufacture complex blade tools (such as taps, broaches), suitable for small batch multi-variety processing.
- Applicable scenarios: Flexible production lines that require frequent tool replacement, or processing duplex stainless steel thin-walled parts.
III. Tool design and process optimization
1. Geometric structure innovation
- Y-type drill: The non-uniform chip groove design can reduce swing and improve the roundness of the hole diameter. Kennametal's patented grinding technology (such as HP process) reduces the risk of chipping by optimizing the distribution of guide edges.
- Large rake angle design: Increasing the rake angle (20°~30°) can reduce cutting force and inhibit cold work hardening.
2. Cutting parameter control
- Low feed rate (<0.1 mm/r): Reduce tool load and avoid hole diameter shrinkage caused by material rebound.
- Medium cutting speed (<200 m/min): Balance efficiency and tool life to prevent overheating.
3. Cooling and lubrication
Use high-pressure coolant to flush the chips and reduce adhesion. For deep hole processing, use internal cooling tools to enhance chip removal.
For difficult-to-process stainless steel, tool selection needs to comprehensively consider material hardness, processing stage (rough/finishing) and cost-effectiveness. Carbide and coated tools have advantages in versatility, while CBN and new structural tools (such as Y-type drills) provide solutions for high-precision requirements. In the future, with the development of coating technology (such as nano-composite coatings) and additive manufacturing processes, the wear resistance and customization capabilities of tools will be further improved.
