Description

The 5С280ПФ3 is a CNC bevel gear cutting machine built by Saratov Heavy Gear-Cutting Machine Tool Plant (SZTZS) — a recognized leader in Russia and the CIS for heavy gear-processing equipment, operating since 2009. The machine is designed for both rough and finish cutting of bevel and hypoid gears with circular arc teeth, achieving accuracy grade 5–7 per GOST 1758-81.

It handles workpieces up to 800 mm in diameter with a maximum module of 16 mm and accommodates gears with 10 to 150 teeth. Gear cutting can be performed by either the generating method or the plunge method, using face gear-cutting heads as the cutting tool.

The CNC system is built on a SIEMENS S7-300 programmable controller with a CPU 315T-3PN/DP processor and SINAMICS S120 servo drives; during operation it continuously calculates and monitors the mutual position of all machine axes in real time, ensuring consistent tooth form accuracy throughout the cutting cycle. The 5С280ПФ3 is a universal machine designed for easy changeover between workpiece geometries, making it equally at home in single-piece prototype work, small-batch production, and medium-series manufacturing across a broad range of mechanical engineering industries.
