ROYAL 5C PNEUMATIC COLLET CLOSER FOR MANUAL LATHES & GRINDERS Proudly Made in U.S.A. q The Royal 5C pneumatic collet closer enables 5C collets to be used on any manual lathe or workhead. q Collet nose guaranteed accurate to 0.000" TIR or better. q Fast opening/closing action makes the Royal pneumatic collet closer a great choice for high production applications. q Closer is very easy to actuate, resulting in minimal worker fatigue and maximum productivity. q The air cylinder incorporates a large diameter piston, providing strong grip force on the workpiece. q Royal 5C Pneumatic Collet Closer incorporates several modern safety features designed to help shops meet OSHA and NIOSH requirements. Unlike other collet closers, there are no exposed rotating parts on the outboard side of the machine. q Pneumatic collet closer assembly includes air cylinder, custommachined rear end spindle adapter, drawtube, and cam-lock collet adapter. Air controls sold separately. Royal collet closers are also well-suited for use in fourth and fifth-axis workholding applications.

ROYAL 5C EXPANDING COLLETS q Unlike chucks and most collets that grip the OD of a workpiece, 5C expanding collets are designed to grip on the ID of a part. q Accu-length design ensures precise workpiece positioning no z-axis movement. q Collet head is easily machined to required size. Can be re-machined as necessary. q Concentricities of + 0.0002" can typically be achieved using Royal 5C expanding collets. q Made from 1144 steel that can be hardened after machining for wear resistance. q Additional head lengths and diameters available. Contact us for information. Head is easily machined to required size by customer. See chart for range. Precision ground body for excellent workpiece concentricity.

ROYAL ULTRA-PRECISION ER COLLETS 0.0002" TIR Inch and Metric Sizes Royal ER Collets are available in both inch and metric sizes. This optimizes the surface contact between the collet and cutting tool and results in higher accuracies, stronger grip force, better part finishes, and longer cutting tool life. Sealed Models Available For precise coolant delivery to the tip of the cutting tool. Large Inventory All sizes are in-stock, ready for immediate shipment. Extremely Accurate Runout is guaranteed to be 6 microns (0.0002") TIR, or better. Each collet is inspected to this standard prior to shipping. Wide Gripping Range Royal standard ER Collets contain 16 slots, providing a larger gripping range than other brands. Heavy Duty Construction Royal ER Collets are made from high-grade steels imported from Germany and are hardened for long life. Great Value Very competitive prices make these high-quality ER Collets the best value in the industry. ROYAL SEALED ULTRA-PRECISION ER COLLETS Short slots block flow, ensuring that all coolant is delivered thru the cutting tool. A Perfect Match to Your Cutting Tool Diameter All Royal ER Collets are available from stock in both inch and metric sizes. This is very important because it enables you to select a collet that has been ground to your precise cutting tool size. Using a collet that is perfectly matched to the cutting tool diameter ensures that full surface contact is achieved, resulting in higher gripping force, better accuracy, less vibration, better surface finishes, and longer tool life. q Ultra-Precision Accuracy 0.0002" TIR guaranteed. q High-pressure approved to 1400 psi. q Unique design is mechanically sealed by virtue of the rear slots terminating prior to the annular groove, completely blocking the path of coolant flow to the front of the collet. q When using thru-coolant cutting tools, these collets ensure 100% coolant delivery to the tip of the cutting tool. q Superior to collets sealed with silicone/rubber plugs because plugs are limited to lower operating pressures and are subject to wear. q Unlike standard ER collets, sealed models do not have a wide collapsibility range, requiring the collet bore to be matched to the cutting tool shank diameter. Other Brands Single Point Contact when Using Metric Collets to Hold Inch-Sized Tooling, or Vise Versa Royal Brand Full Surface Contact Because Royal ER Collets are Ground to Exact Inch and Metric Sizes 47
