High-Efficiency Automotive Transmission Gears & Shafts

Supports deep axial turning passes on long hardened shafts (HRC 56–62), ensuring zero dimensional taper and absolute geometric cylindricity from end to end.

Large Industrial Hydraulic Cylinders & Plungers

Handles extended, continuous skiving and hard-turning operations over large surface areas without requiring mid-pass insert indexing.

Bearing Inner & Outer Rings Face Turning

Eliminates localized edge chipping during wide-face plunging and continuous race tracking, stabilizing sub-micron flatness.

Precision Die & Mold Core Finish Profiling

Maximizes continuous high-speed cutting path length in hardened tool steels (HRC 60+), achieving mirror-like finishes ( ≤0.4) directly from the lathe.

Models & Specs

1. Continuous Seamless Cutting Edge vs. Fragmented Small Tips

Standard tipped CBN inserts only have a microscopic patch brazed at the very corner. If your depth of cut ($a_p$) exceeds 0.5 mm or if you are running an axial profiling path with a variable depth, the cutting action forces the chips across the brazing boundary line. This causes rapid thermal erosion, seam melting, and severe edge splitting.

Uking’s Full-Edge Brazed CBN Inserts feature a continuous, complete length of industrial-grade PCBN along the entire edge profile. Sintered and laser-welded with high-density vacuum diffusion techniques, there are zero internal seams along the active cutting length. This permits you to significantly increase your single-pass axial depth of cut (ap), transforming slow, multi-pass cycles into a single, high-efficiency finish pass.

2. Superior Rigidity of Carbide Substrate with PCBN Efficiency

Unlike Solid CBN inserts which can sometimes suffer from structural brittleness on small, intricate tool bodies, Whole Welding inserts utilize the high impact dampening properties of a dense tungsten carbide backing.

The carbide base absorbs spindle micro-vibrations and high bending moments during deep cuts. Meanwhile, the continuous whole-welded PCBN edge handles the immense friction temperatures (≥ 900°C) of hard turning (HT). This optimal hybrid structure delivers unparalleled surface finish consistency (Ra≤0.4 μm) over high-volume automated production shifts.

Are your automated precision hard turning lines constantly leaving microscopic step-marks, or are your brazed CBN corners failing prematurely whenever you increase your depth of cut (ap) on long hardened shafts?

Stop limiting your cycle times with cheap, single-tipped inserts that restrict your machining depth and melt under prolonged thermal loads. Backed by 20 years of vacuum-diffusion and advanced automated laser-welding synthesis engineering authority in Henan, China, Uking Diamond supplies high-output manufacturing plants with industrial-grade Whole Welding Full-Edge CBN inserts that keep your finishes perfect and your production lines profitable.

Because full-edge welded PCBN inserts are precision-engineered, high-performance production assets rather than generic commodity shop items, we align exclusively with high-intent industrial evaluations rather than distributing unmonitored free samples.

Ready to double your depth of cut and achieve seamless finish surfaces? Contact our global tool engineering division today with your current ISO configuration (e.g., CNGA 120408), your exact workpiece dimensions/hardness (HRC), and your current machining cycle limitation (e.g., seam cracking or multi-pass slowdowns). Our team will instantly activate your Corporate Whole-Welding Evaluation Pass: obtain a prioritized test batch of our advanced full-edge welded inserts at direct factory-wholesale pricing, with 100% of the sample evaluation fee fully credited back to your account upon your first bulk commercial order.
