Severe Interrupted Automotive & Train Hard Turning

Survives continuous cross-hole, splines, and keyway interruptions when roughing hardened steel gears ( 58–65), preventing crack propagation along the flank.

Heavy-Duty Steel Mill Rolls & Slag Castings

Effortlessly slices through the uneven, abrasive oxidized skin and structural sand inclusions of chilled cast iron and high-manganese steel mill rolls.

Large-Diameter Wind Power Bearings & Slewing Rings

Supports extra-large depth of cut ( ≥2.0 mm) and aggressive feed rates during the initial roughing passes of large-scale forged rings.

Aerospace High-Temperature Superalloys Roughing

Maintains exceptional chemical inertness against thermal sticking and diffusion wear when scaling dense Inconel or titanium forged components.

Models & Specs

1. Isotropic Solid Phase Homogeneity vs. Layered Composites

While tipped or composite tools rely on a thin functional layer backed by carbide, they introduce an internal thermal expansion mismatch line. When a tool hits a deep keyway interruption or a severe casting void at 200 m/min, this composite boundary acts as a stress-collector, leading to severe splitting.

Uking’s Solid CBN inserts feature a 100% homogeneous solid phase block. Sintered under intense HPHT parameters, the pure crystalline microstructure disperses impact energy equally in all directions (isotropic toughness). This eliminates structural delamination vulnerabilities completely, enabling machine operators to run heavy, aggressive dry cuts that would instantly fracture standard layered tooling.

2. Fully Regrindable Lifecycle: Maximizing Your Capital Asset Return

In high-volume heavy industries, a tool is not just a consumable—it is a production asset.

Because Uking’s Solid CBN series contains no carbide backing, the entire insert body consists of cutting-ready PCBN material. Once the initial cutting edges reach their wear limits, the inserts can be reground and re-lap polished multiple times to original specifications.

This multi-lifecycle profile offsets the higher initial purchase price, slashing your long-term tooling cost-per-part over months of continuous production campaigns.

Why Choose Uking Diamond Solid CBN?

Zero Delamination Risk Under Interruption: 100% alloy-free solid block composition ensures absolute structural immunity against severe mechanical impacts.

Extreme Depth of Cut ( ap ) Resilience: Allows maximum material removal rates (MRR) per pass without the clearance constraints of brazing or layering zones.

Multi-Cycle Regrindable Economy: Entire body geometry can be multi-stage reground and re-sharpened, maximizing tool life and destroying long-term inventory costs.

Supreme Thermal Red-Hardness: Retains mechanical edge hardness at intense friction zone temperatures up to 1100°C, perfect for continuous high-speed dry turning.

PCD Models & Specs

1. Diffusion Bonding Immunity Against Thermal Delamination

Standard tipped CBN tools rely on a razor-thin layer of vacuum braze silver/copper paste. When cutting hardened steel at high speeds, temperatures in the shear zone frequently spike past 800°C, degrading the braze strength and causing the CBN tip to instantly fly off (delaminate).

Uking’s Hybrid Welding technology utilizes an ultra-high-pressure high-temperature co-diffusion process. The transition alloy layer morphs into the carbide backing and the CBN matrix simultaneously, creating a seamless gradient structural profile. With zero conventional braze seams to degrade, the insert operates smoothly at elevated cutting velocities ( Vc≥200 m/min) with absolute process safety.

2. Micro-Honed Chamfer Geometry & Tailored CBN Content

To combat edge micro-chipping, every Hybrid Welding batch receives customized, automated edge preparation:

High-Content CBN (~85%–95%): Sintered with a metallic binder (Co-Al) network, optimizing thermal conductivity and fracture toughness for heavily interrupted cast iron milling.

Low/Medium-Content CBN (~50%–65%): Bound within a ceramic matrix (TiN/TiC), maximizing chemical wear resistance and crater hardness for high-speed continuous hard turning ( ≥180 m/min ).

Each insert edge is polished with specific S-lands (honed round edges) or T-lands (negative chamfers) to protect the tip from sudden mechanical fracture during the initial cut entry.

Why Choose Uking Diamond Brazed CBN Inserts?

Delamination-Free Process Stability: Diffusion-welded interfaces guarantee zero tip structural detachment, even during high-temperature dry cut cycles.

Cost-Per-Edge Optimization: Features solid hybrid integration that allows multi-tip configuration per blank, multiplying your cutting corners and reducing tooling costs.

Elimination of Grinding Processes: Replaces expensive, slow grinding with high-efficiency hard-turning, reducing total cycle times by up to 60%.Strict Micron-Level Runout Control: Each insert is laser-inspected to fit flawlessly into international standard tool holders with zero centerline indexing deviation.

Models & Specs

1. Full-Surface Solid Sintering vs. Tiny Brazed Patches

Standard tipped CBN inserts restrict your production limits because they only offer 1 or 2 usable brazed corners, leaving the rest of the carbide body wasted. Furthermore, deep cuts (≥1.0 mm) are impossible because the material shear zone would spill over onto the fragile brazing line, triggering immediate severe cracking.

Uking’s Indexable CBN Inserts are built with zero spatial boundaries. The entire upper and lower operating faces consist of industrial-grade PCBN material integrated directly into the carbide spine under large-scale HPHT press blocks. This solid cross-section allows you to increase your depth of cut to the physical machine limits without fearing edge separation, making it the premier choice for aggressive metal removal rates.

2. Up to 8 Edges: The Ultimate Tooling Cost Destroyer

In global automotive sourcing, purchasing managers look beyond the initial purchase price—they hunt for the lowest Cost-Per-Part (CPP).

By utilizing a negative style geometry with no fixing hole (clamped via robust top-clamp holders), our CNMN and SNMN composite series unlock up to 6 or 8 fully operational cutting corners on a single insert body.

Combined with our high-thermal conductivity binder network, each individual corner outlasts conventional carbide by 80×, shrinking tool-change downtime and collapsing your warehouse tooling inventory costs.

Why Choose Uking Diamond Overall Composite?

8 Usable Corners per Insert: Multiplies your usable tooling edges, automatically cutting your tool procurement budget by up to 60%.

Massive Depth of Cut ( ap​ ) Capability: Solid layer design permits deep roughing passes without encountering fragile brazed line stress fatigue.

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.
