A line of electro-permanent workholding magnets from SAV North America is designed to accommodate a range of material sizes and shapes for milling operations. HEX Pole milling magnets are said to deliver greater holding power per square inch with six-sided (hexagonal) pole configurations versus typical square-shaped magnets.
The magnets can be mounted on the machine center table via clamps or palletized to a referencing system by a plug-and-socket power connection. Top tooling is available in both fixed and flexible pole configurations to allow five-axis access to the workpiece. Designed with an industrial-grade, metallic-filled top plate that prevents chip adhesion, the magnets are fully sealed to prevent short circuiting due to coolant leakage from machines during the cutting process.
The magnets are available in various sizes in three models. The HEX 220 HP (high performance) and HEX 220 SP (standard performance) models operate on 220-V service and are ideal for center-driven workpieces, the company says. The HEX 220 HP measures 3.9" × 6.3", while HEX 220 SP models are available in two sizes: 9" × 9" and 12" × 12". The HEX 480 model operates on 480-V service and is designed with an extended base for hold-down clamps. This model is available in sizes ranging from 10" × 14" to 20" × 30".
