Retractable Mandrels The Sunnen KR and BLR series of honing mandrels with retractable stone assemblies ensure greater efficiency in virtually all bore sizing and finishing operations. Mandrel Adapter The new retractable KR mandrel series is available for diameter ranges from .185"-.744" (4,70-18,90 mm). The longer BLR series of retractable mandrels is also available for the same diameter range, and incorporates a longer stone. Stone Wedge Wedge Guide Retractable Mandrel Options Diamond Plated Super Mandrels — Designed to provide a long-wearing guide shoe to increase mandrel life in some applications…plus faster stock removal in difficult materials (chrome, carbide). Plated with 220 grit diamond. Available 4-6 weeks after receipt of order. Retractable mandrel and stone assemblies are available at the same price as the nonretractable mandrel units. Carbide Shoe Mandrels — (Available on Special Order) Two types of Carbide Shoe Mandrels are available for highproduction applications. Available in either Round Carbide Rod Inserted and Full Carbide Shoe Mandrels. In the correct application they will last significantly longer than standard hardened mandrels and prevent galling in exotic materials such as 303 stainless steel. When ordering full-carbide type specify starting and finish diameter. Available 4-6 weeks after receipt of order. Benefits of Sunnen’s Retractable Mandrels: • Stones are retracted from the cutting position for much easier loading and unloading of parts which increases production and lowers manufacturing costs. • Stronger mandrels remove stock at a faster rate, increasing production speeds and lowering cost per part honed. Extended Shank Mandrels — (Available on Special Order) Extended Shank Mandrels are available for honing parts that are too long to be honed with a standard mandrel. Available 4-6 weeks after receipt of order. • Units come with extended wear surfaces (shoes) standard, in either hard steel or plated diamond. This ensures longer service life and significantly reduces centerline changes from cycle to cycle. Also, downtime is lowered which increases productivity and reduces unit costs. Metal Bond Superabrasive Insert Mandrels — (Available on Special Order) For applications where a long lasting mandrel is needed and the materials being honed reacts negatively with either a hardened or carbide shoe mandrel. Single or double insert mandrels in either Borazon/CBN or diamond are available. Available 4-6 weeks after receipt of order. • Mandrel units have hardened wedges to prolong wedge life. This assures high performance honing from start to finish for better cost efficiency. • The stone retraction feature is ideal for use in automated applications facilitating loading and unloading, reducing labor costs. • Retraction marks and scratches that can occur when taking the part off the mandrel after honing are greatly minimized. This ensures a consistently higher-quality end product.
