We offer cnc pressure foot. Assembly CNC Pressure Foot Clamping Holder for CNC Router Spindle Model: Diameter: 65mm, 80mm, 100mm, 105mm, 125mm This cnc router spindle pressure foot holder is assembly. The CNC pressure foot attaches to the Z axis spindle of your CNC router and provides clamping force directly around the cutter bit. This clamping approach is particularly effective for machining small parts and thinflexible materials that cannot be held by traditional clamping methods. Adjustable body comes complete with precision machined bearings, hardened and ground slides, and round rolling balls to prevent scratches or marks on delicate finishes. As clamping methods have vacuum clamping, edge clamping, screwsbrad nails, etc, but each has its advantage and disadvantage. This pressure foot is designed to compensate for some material warping and tables that are not perfectly flat, particularly effective for machining small parts and thinflexible materials that cannot be held by traditional clamping methods without using tabs or adhesives. This CNC pressure foot is compatible with most CNC routers and CNC milling machines. It is mounted onto your cnc router spindle, similar to many dust collection covers, and provides clamping force directly around the cutter bit.
