High-precision 45° Step-Lap Mitered Laminations, Built-Up 3-Phase Cores, and Cut-To-Length Sheets. Fabricated from prime 27-105 SHOYU steel and exported worldwide from Bengaluru, India.

BURR HEIGHT: < 0.010 mm EXPORT HS: 85049010

PRECISION CNC MITER CUTTING

7-Step Step-Lap Mitered Cores

Our CNC oscillating shears automatically cut 45° and 135° angles with continuous step-lap offsets (3.5mm to 5mm). By staggering the joint gaps across adjacent laminations, magnetic flux transfers smoothly with zero localized saturation, achieving up to 18% lower iron losses and 4-6 dB lower acoustic noise.

STEP-LAP JOINTS Up to 7 Steps Automated stack offset

BURR HEIGHT < 0.010 mm Carbide sheared edge

CUT TOLERANCE ± 0.1 mm Sub-millimeter CNC accuracy

POWER CLASS Up to 765 kV Distribution & EHV Grids

Product Range: Loose 45° step-lap stacks, banded center limb sub-assemblies, and fully built-up 3-phase cores.
Punching Options: V-notches, center-limb locating holes, yoke tie-rod holes, or modern holeless designs.
Incoterms Supported: FOB Chennai / Nhava Sheva / Tuticorin, or CIF / CFR to any destination port worldwide.
