Kunshan Meiyaxing Hardware Machinery Co., Ltd. is a direct branch of Hong Kong Meiya International Trading Co., Ltd. in China. It owns its own tool brand: MANF, and engages in the sales and operation services of CNC cutting tools. It provides tungsten carbide end mills, milling inserts, turning inserts, grooving and parting inserts, drilling and boring inserts, multi-functional inserts, threading inserts, and other indexable inserts and their matching tool holders and tool holders. Furthermore, it has established long-term strategic partnerships with many well-known manufacturers, with joint R&D, design, and production teams, advanced equipment, and continuously innovative technological strength. It is committed to mutual cooperation, guided by technical services, forming a mutually supportive industrial chain to solve various processing problems for manufacturing enterprises.
In modern machinery manufacturing, especially in the fields of high-volume precision machining such as automobiles, construction machinery, and aerospace, the requirements for processing efficiency and precision of difficult-to-machine materials (such as hardened steel and cast iron) are becoming increasingly stringent. Cubic boron nitride (CBN) Cutting tools, with their extremely high hardness and excellent thermal stability, have become an ideal alternative to grinding.
When standard cutting tools cannot meet complex machining needs, non-standard CBN forming tools have emerged. They combine the ultra-hard properties of CBN with the high efficiency of "forming" machining, providing an ultimate solution to challenging machining problems.
III. When to Choose Non-Standard CBN Forming Tools?
Although non-standard CBN forming tools offer significant advantages, their initial investment is high (design, mold making, and sharpening costs), and they require high machine tool rigidity and cutting stability. Therefore, choosing the right application time is crucial.
1. Facing High-Volume, High-Temperature Production Needs
Typical Scenarios: Automotive transmission gears, engine valve seats, steering knuckles, compressor crankshafts, etc.
Judgment Basis: When daily or annual output reaches a certain scale, the tooling cost per part using non-standard CBN forming tools is actually lower than that of standard inserts. This is because standard inserts may require frequent tool changes and adjustment compensation, leading to excessive downtime.
2. Machining Complex Contours with Required "Copying" Precision
Typical Scenario: Irregularly shaped parts with rounded corners, tapers, or special profiles.
Judgment Basis: If standard inserts are used to machine complex contours via CNC program fitting (macro program or CAM), not only is programming complex and machining time long, but tool marks or out-of-tolerance contours are also prone to occur. In this case, using a forming tool can directly "copy" a perfect contour.
3. Traditional Carbide Tool Life is Extremely Low
Typical Scenario: Machining high-silicon aluminum, high-chromium cast iron, and hardened steel (HRC 55 and above).
Judgment Basis: When the life of carbide tools is extremely short, leading to frequent tool changes and increased scrap rates, switching to CBN material is often the only economical option. Especially for materials containing carbide particles, CBN's wear resistance far exceeds that of carbide.
4. The equipment has sufficient rigidity, aiming for "turning instead of grinding."
Typical scenario: Shaft parts requiring precision machining, such as hydraulic piston rods and motor shafts.
Judgment basis: If a factory possesses high-rigidity, high-precision CNC machine tools (such as OKUMA, MAZAK, etc. high-rigidity lathes) and wants to reduce investment in cylindrical grinding machines, using non-standard CBN forming tools for precision machining is a very suitable opportunity.
Non-standard CBN forming tools are not just cutting tools, but also a precision process solution for specific problems. They possess comprehensive advantages unmatched by other cutting tools in machining scenarios involving high hardness, high volume, and complex contours.
Decision recommendation: Consider introducing non-standard CBN forming tools when you encounter the following situations:
· Machining ferrous metals with a hardness > HRC 45;
· High annual production volume with high cycle time requirements;
· Complex part contours and high precision requirements;
· Existing grinding processes are costly and inefficient.
By collaborating with professional CBN tool manufacturers and tailoring the tool body, cutting edge treatment, and insert groove design, unexpected cost reductions and efficiency improvements can often be achieved.
