View Specifications →In modern high-speed CNC milling and automatic cutoff operations, selection of cutting tools directly dictates dimensional accuracy, kerf roughness, and overall cycle times. As a premier Famous Carbide Slitting Saws Supplier & Exporters, JIAYAN Superhard utilizes sub-micron to ultrafine tungsten carbide (WC) matrix formulations enriched with cobalt binder phases (6% to 12% Co).
Unlike conventional High-Speed Steel (HSS) slitting blades that soften at elevated temperatures (above 500°C), solid carbide slitting saws maintain exceptional hot hardness up to 1000°C. This allows production facilities to increase cutting speeds ($V_c$) by 300% to 500% while eliminating thermal distortion of the blade disc.

Located in Wuhu’s premier industrial hub, JIAYAN Superhard operates a fully integrated Industry 4.0 manufacturing complex. Equipped with 5-axis CNC grinding centers (Walter Helitronic, Rollomatic, ANCA FX7), automated robotic loading cells, and closed-loop laser measurement systems, we deliver uncompromising precision across high-volume production orders.
By controlling the entire production value chain—from tungsten carbide powder formulation and Hot Isostatic Pressing (HIP) sintering to 5-axis CNC tooth profiling and vacuum PVD coating—we guarantee 100% batch-to-batch consistency and total price-to-performance dominance.
How enterprise buyers lower cost per cut through custom engineering, regrinding programs, and extended tool life reliability.
Evaluating purchase price alone overlooks machine downtime expenses. By extending edge retention by 300%, JIAYAN carbide saws minimize blade swap frequency, significantly raising overall CNC spindle utilization.
Custom outer diameters (15mm to 350mm), ultra-thin kerfs down to 0.15mm, non-standard arbor bores, drive pin holes, and specialized clearance angles tailored precisely to your specific workpiece metallurgy.
High-density solid carbide bodies allow up to 5 to 8 precision regrinding cycles on CNC tool grinders without compromising structural core stability, driving lifetime cost per cut down to historic lows.

Detailed technical solutions to common machining questions, feed rate calculations, and blade selection criteria.
Solid carbide slitting saws provide significantly higher micro-hardness (HRA 91.5-94.2 vs. HRC 64-66 for HSS) and superior thermal stability up to 1000°C. This allows cutting speeds ($V_c$) 3 to 5 times faster than HSS, dramatically reduces blade deflection on narrow kerfs, eliminates cut burrs, and extends overall tool wear life by 10x to 25x depending on workpiece hardness.
Spindle speed is calculated via $n = (V_c \times 1000) / (\pi \times D)$, where $V_c$ is cutting speed in m/min and $D$ is saw diameter in mm. Table feed rate is calculated via $V_f = n \times z \times f_z$, where $z$ is the number of teeth and $f_z$ is feed per tooth (typically 0.005mm to 0.03mm per tooth for thin carbide saws). For tough alloys like stainless steel or titanium, reduce $V_c$ by 30% and increase coolant delivery pressure.
Select DIN 1837 (Form A) fine pitch for thin-walled profiles, fragile workpieces, and shallow slot depths (< 3mm). Choose DIN 1838 (Form B) coarse pitch for solid stock cutoffs and deep slots where larger chip gullets are necessary. Choose Form C (HZ) split-chip breaker geometry for high-strength steel alloys, heavy roughing cuts, or long-chip materials to prevent vibration chatter.
Primary causes of carbide slitting saw failure include axial arbor run-out (> 0.005mm), excessive lateral backlash, improper feed acceleration, or chips re-cutting in the gullet. To prevent breakage: (1) Ensure spindle flanges are clean, parallel, and cover at least 1/3 of the saw diameter; (2) Use high-pressure flood coolant or MQL misting; (3) Avoid stopping spindle rotation while the saw blade is engaged in the slot.
PVD coating is highly recommended when machining abrasive or hard metals (>30 HRC), sticky materials prone to Built-Up Edge (like aluminum or pure copper), or high-temp superalloys. AlTiN / nACo coatings block oxidation heat, while DLC coating provides an ultra-low friction barrier ideal for burr-free micro-slitting in copper lead frames.
