Process brake disc - Halnn CBN inserts
Halnn is a high-tech enterprise that specialized in production of CBN inserts, and is the first R&D company focus on the cutting tools for processing the gray cast iron, all kinds of wear resistant cast iron/cast steel, harden steel materials in this industry.
Halnn sets up CBN products national workstation and engineering technology research center, which own a complete testing laboratories and advanced detection equipment, it ensure that each product owns unparalleled quality and performance by virtue of professional, full industry chain advantages and focus, rigorous work processes.
The superiority of Halnn solid CBN inserts:
Excellent anti - fracture performance
Good wear resistance
Excellent chemical stability
Higher cutting efficiency
Longer cutter lifetime
Indexable cubic boron nitride sintered body - with more cutting edges
Halnn CBN insert is used in high-speed cutting conditions,
(1) It is used for milling, side milling and other processing of rotating inserts.
(2) It is used for weak rigid rotated cutter.
(3) It is used for rotating inserts of the rigid mold cavity while the cutting speed is generally no higher than 2000m / min.
(4) The cutting speed of the workpiece rotation is generally less than 1000m / min.
Halnn super-hard subverted traditional and researched new CBN insert, CBN inserts own better impact resistance and wear resistance through upgraded, which can be used for intermittent cutting and milling, the effect of Halnn cbn insert is very significant when the workpiece is used for roughing and semi-finishing in the brake disc, gearbox, crankshaft and other auto parts industry. Special for continuous cutting of the bearing steel, high-speed steel and other hard steel workpieces, it also has been widely used in the wind power, machine tools, gear industries.

When processing the brake disc, the surface roughness and geometric tolerance are basic guarantee of processing quality, the competitiveness of auto parts industry depend on the processing efficiency. BN-S30 solid CBN insert has achieve good performance in the geometric tolerance (parallelism, flatness),roughness and processing brightness of machining the brake disc, and the processing efficiency of the brake disc is significantly improved.
