Core Question: Can your processing costs withstand the continuous rise of tungsten carbide? As of the beginning of 2026, the price of tungsten carbide powder has soared by more than 200% compared with 2024, and the price of terminal cutting tools has generally increased by 30%-60%. Many manufacturing enterprises are trapped in the dilemma of "no way to reduce costs and obstacles to improving quality". In fact, the key to breaking the situation has long emerged - PCD (Polycrystalline Diamond) and CBN (Cubic Boron Nitride), once regarded as "high-end exclusives", have now become the optimal alternative to tungsten carbide with the reversal of cost performance, and Moresuperhard is the core partner to help you fully grasp this dividend.
In the past, PCD and CBN were "inaccessible" due to their high initial prices and only used in special difficult-to-process scenarios; now, with the skyrocketing cost of tungsten carbide and the stable price of super-hard tools, the total life cycle cost of the two has reversed, fully demonstrating economic efficiency and practicality in mainstream scenarios. Combined with Moresuperhard's exclusive supporting solutions, the cost reduction and efficiency improvement can be taken to the extreme.
As the second hardest super-hard material after diamond, CBN's core advantages are ultra-high thermal stability (maintaining cutting performance above 800℃) and chemical inertness. When processing high-hardness ferrous materials such as hardened steel and chilled cast iron, it can completely avoid the common adhesive and diffusion wear of tungsten carbide, eliminating the need for frequent tool changes.
Actual test data speaks: When turning GCr15 hardened steel (HRC62), one domestic CBN insert can process more than 400 workpieces, while tungsten carbide can only complete about 50 workpieces - even if the unit price of CBN is 60% higher, the processing cost per workpiece can still be reduced by 80%, and the subsequent grinding process can be omitted, shortening the cycle and energy consumption.
More importantly, Moresuperhard can provide high-quality CBN blanks, combined with exclusive grinding wheels and grinders, to accurately match the advantages of domestic CBN technology. Whether it is intermittent cutting or continuous processing, it can achieve high-precision edge forming, maximize the service life and efficiency of CBN tools, and eliminate the need to rely on imported supporting facilities, further reducing the comprehensive cost.
If CBN focuses on "hard steel", PCD monopolizes the processing of "soft and abrasive" materials - sintered from micron-level diamond particles, its hardness is close to natural diamond, suitable for abrasive materials such as high-silicon aluminum alloy, copper alloy, and carbon fiber composite materials (CFRP), which is a rigid demand in the automotive, aerospace and other fields.
Taking the processing of integrated die-cast rear floor of new energy vehicles as an example, after replacing with PCD brazed tools, the tool life is increased by more than 10 times, the tool cost per workpiece is reduced by 85%, and fully automated continuous production is realized. Note: PCD is strictly prohibited for processing ferrous materials; iron elements will cause it to fail at high temperatures. Finding the right application boundary can maximize its value.
Moresuperhard specially provides PCD blanks, combined with special grinding wheels and grinders, and can customize grinding solutions according to your processing scenarios, solving the pain points of difficult PCD edge forming and insufficient precision, converting ultra-high wear resistance into tangible cost advantages, and quickly adapting to existing production lines without additional equipment transformation.
Nowadays, PCD/CBN is no longer an option "only used when necessary" - in batch and automated production lines, its long-life feature can reduce tool change frequency, reduce downtime, and improve yield. The hidden benefits combined with direct cost savings make the comprehensive benefits of super-hard tools far exceed those of tungsten carbide. For enterprises processing high-silicon aluminum, hardened steel and other materials, insisting on using tungsten carbide will instead push up costs.
The core value of Moresuperhard is to make PCD/CBN "affordable and easy to use": from the supply of high-quality PCD/CBN blanks, to the one-stop supporting of special grinding wheels and grinders, and then to subsequent technical support, it fully adapts to domestic super-hard tool technology, breaks the price barrier of imported supporting facilities, and converts every investment into practical cost reduction effects.
1. Ensure sufficient machine rigidity, control the spindle runout within 0.005mm to avoid edge chipping;
2. Optimize cutting parameters: 80-250m/min for CBN processing hardened steel, 300-1500m/min for PCD processing aluminum alloy;
3. Prioritize pilot projects in automated and high-volume production lines to quickly amortize initial investment;
4. Choose a reliable supplier like Moresuperhard to obtain one-stop blanks, grinding wheels, grinders and technical support, eliminating the need for multi-party docking and reducing switching costs.
The high price of tungsten carbide is reshaping the value logic of cutting tools. The reversal of cost performance of PCD and CBN is not a "high-end replacement", but a "rational choice". The PCD/CBN blanks, special grinding wheels and grinders provided by Moresuperhard are the key to helping you seize the dividends of this technological migration.
No need to worry about "initial investment" or "adaptation problems" - Moresuperhard's one-stop supporting solution allows you to easily switch to super-hard tools, realizing a direct reduction in processing costs and doubling efficiency.
