Beijing Youlian Huah Ceramic Materials Co., Ltd. (YLHH) is headquartered in Changping, Beijing, specializing in polycrystalline cubic boron nitride (PCBN) and cubic boron nitride (CBN) cutting inserts. Under the YLHH Tools brand, we serve automotive, aerospace, mold & die, and general engineering customers worldwide with hard-turning solutions that replace grinding.
Company Overview
YLHH focuses on superhard cutting materials with full-process quality control — from raw material inspection and PCBN composite production to precision grinding, laser marking, and packaging. Our product strategy centers on four ISO-standard insert families: VNGN, RNMN, RCGN, and SNMN, covering diamond, round, small-round, and square geometries for diverse machining scenarios.
Our Technical Application Support Center helps customers with grade selection, cutting parameter recommendations, and sample testing for hard turning, facing, and finishing of hardened steel (HRC 45–68), cast iron, and sintered metals.

Industries We Serve
Automotive
Bearing races, gears, and hardened shafts — replace grinding with hard turning to reduce cycle time.
Aerospace
High-hardness alloy components with stable surface finish targets Ra 0.4–0.8 µm.
Mold & Die
Cold-work tooling, roll profiling, and facing under interrupted cutting conditions.
General Engineering
Hydraulic parts, cast iron, and sintered metal rough/finish machining.
Technology
YLHH develops proprietary PCBN grades including FB-2 and FB-1 (~50–65% CBN content), balancing wear resistance for continuous cuts and edge toughness for interrupted operations. Products conform to ISO indexable insert geometries and standard tool holder systems.
Quality & Certification
- ISO 9001:2015 Quality Management System — recertified in 2026
- Laser marking with full batch traceability from incoming material to shipment
- Incoming inspection and final dimensional checks to ISO tolerances
