Horizontal Double Disc Grinding Precision

The HD Series horizontal double disc surface grinders deliver precision and productivity across a wide range of applications, from compact, high-precision components to large, heavy-duty parts. The lineup begins with the HD3, a compact model designed for thin workpieces up to 25 mm, ideal for parts like pins, rollers, and gears. For greater flexibility, the HD5 expands capacity to 130 mm, excelling in automotive and aerospace applications such as pistons, disc brakes, and bearing races.

For heavier workloads, the HD7 accommodates parts up to 150 mm, making it well-suited for connecting rods, bushings, and pump components, while the HD10 tops the range with a 180 mm capacity for oversized bearing races and other demanding applications. Together, the HD Series offers manufacturers a complete grinding solution, combining flexibility, durability, and precision across a diverse range of industries.
