Workholding & Clamping

About workholding & clamping

Workholding and clamping components are essential for securing workpieces during machining, assembly, and inspection processes. This category encompasses a range of devices designed to provide rigid, repeatable, and precise workpiece location. Vises, such as precision machine vises and self-centering vises, are commonly used for milling and grinding operations, characterized by jaw width, opening capacity, and clamping force. Toe clamps offer low-profile clamping solutions, often specified by clamping height, thread size (e.g., M8, 1/2-13 UNC), and material (e.g., hardened steel, aluminum). Chucks, including 3-jaw, 4-jaw, and collet chucks, are primarily used for rotary workholding on lathes and rotary tables, defined by their diameter, jaw type (e.g., hard, soft), and through-hole capacity. Magnetic bases provide temporary, repositionable fixturing for indicators and light workpieces, with pull force ratings and base dimensions being key specifications. Fixture plates, available in standard grid patterns (e.g., 50mm, 2-inch) and materials like aluminum or steel, serve as foundational elements for building custom workholding setups, often featuring tapped holes and dowel pin bores for modularity. Material selection for these components often includes hardened tool steel, cast iron, or anodized aluminum, depending on required rigidity, wear resistance, and corrosion properties.
