UCSF - Ultra Compact Split Frame E.H. Wachs experience in onsite machining with split frames has led to the Ultra Compact Split Frame, our newest and smallest line. Built with jewel-like precision the UCSF proves that good things come in small packages. Specially designed to accommodate minimal axial and radial clearances, they include low clearance self centering collets for ease of setup. For ships the specification called for an overall height not to exceed 1.75” (44.45mm), including the chipless cutting tool slide. Special compact air motors with variable angle mounting were included to maximize the operating versatility in these tight spaces. UCSF capacities range from .25” (6.35mm) up to 1” (25.4mm) outside diameters.
