5C2 Rotary Indexing Systems User Manual B-119D2. Setting up the Hardinge 5C2 Rotary Indexing System2.1 General Setup1. Fill out the warranty information by visiting www.hardinge.com/rotarywarranty on the internet.2. Place the indexer/rotary table on the machine. Route the cable from the head so that it avoids tool changers and table edges. Cable slack must be provided for your machine’s movements. If the cable is cut, themotor will fail prematurely; replace a damaged cable immediately. Secure the indexer/rotary table to themachine’s T-Slot table as shown below (upright or on it’s back). T-nut packages are available for purchasefor various T-slot tables. Kit includes (2) T-nuts, (2) bolts, and (2) flat washers. Check to verify that allclearances are satisfied in full machine axes movements and that there is no possibility of a collision.3. Place the indexer/rotary table in an area free from chips and coolant where air can circulate freely. Donot let chips pile up over the motor enclosure, as this would prevent proper cooling.4. Connect the 5C2 Rotary Indexer using one of the techniques as described in the Hardinge servo controlor Hardinge 4th axis manual, which will be included with the mechanical unit.5. Route the cable over the back of the mill sheet metal (if using Hardinge Servo Control).6. If adding an indexer to a Hardinge mill using a remote CNC cable or as a true 4th axis, refer to the instructions in the Hardinge 4th axis manual or call the Hardinge service department.7. If using the Hardinge servo control, secure it in required placement. Do not cover any surface of thecontrol, as it will quickly overheat. Do not place the unit on top of other hot electronic controls.7a. Connect the two cables from the indexer to the controller in the appropriate locations.7b. Connect the AC line cord to a 120V AC grounded receptacle. The cord is a three-wire ground typeand the ground must be connected. Power is 120VAC. The power service must supply a minimumof 15 amps continuously. Conduit wire must be 12 gauge or larger and fused for at least 20 amps. Ifan extension cord is to be used, use a three-wire ground type and the ground line must be connected. Avoid outlets that have large electric motors connected to them. Use only heavy duty 12 gaugeextension cords capable of 20 amp load. Do not exceed a length of 30 feet. Permanent installationsshould be hard-wired or installed with locking plugs.7c. Semi-Fourth Axis: Connect the remote interface cable. See separate Hardinge Servo Control manual.14Hardinge Inc.

Instant failure will result.

5C2 Rotary Indexing Systems User Manual B-119D8. Connect air to the quick disconnect fitting on top of the indexer if using a pneumatic collet closer.Quick DisconnectFittingCAUTION: Never use more than 85 psi with the fail-safe collet closer.9. Check the oil level. If it is low, add oil. Use MOBIL Delvac synthetic gear oil 75w-90 only.10. Save the packing materials in case you need to ship the unit.11. At the end of the workday or shift, it is important to clean the indexer/rotary table. The indexer/rotarytable should be free of any chips or grime. Clean with a chip brush and apply a coat of rust preventative.CAUTION: Do not use an air gun around the front or rear seals. Chips may damage the seal if blown in withan air gun.NOTE: Prior to powering on the unit, read and understand the entire control or 4th axis manual.12. Turn on the mill (and servo control, if applicable) and home the indexer by pressing the zero return button. The indexer/rotary table homes in the counterclockwise direction as viewed from the spindle.2.2 Use of Collets, Sure-Grip Expanding Collets, 3-Jaw Manual Chucks, and Face PlatesThe unit accepts standard Hardinge 5C collets, step chucks, ID gripping collets, chucks, face plates, and fixtureplates. When inserting the collet, align the keyway on the collet with the key inside the spindle. Push the collet inand turn the collet closer drawbar clockwise until proper collet tightness is obtained.Part No. BD -0009500-0119Chucks and face plates utilize the 2-3/16 threaded nose on the spindle. We recommend using chucks that are5”/127mm in diameter or smaller and weigh less than 20 pounds. Pay special attention when installing chucks.Always make sure that the thread and the outside diameter of the spindle are free of dirt and chips. Apply a thincoating of oil to the spindle. Screw the chuck on gently until it seats against the rear of the spindle. Tightenthe chuck to approximately 70 ft-lb with a strap wrench. Always use a firm, steady pressure to remove or installchucks or face plates. This is very important to prevent damage to the indexing head.Hardinge Inc.

5C2 Rotary Indexing Systems User Manual B-119D2.3 Hardinge Pneumatic Fail-Safe and High Force Collet ClosersThe Hardinge 5C2 Indexing Head is provided with a manual collet closer as standard. Additionally Hardingeoffers two pneumatic collet closers, the PFS (Pneumatic Fail-Safe) and the PHF (Pneumatic High Force). Both ofthese closers provide an opportunity for operational improvements by reducing operator fatigue and allowing forpossible automation arrangements. Both closers utilize an original Hardinge concept of force amplification thathas been historically proven to provide long life and effective operation even under demanding applications. TheHardinge force amplifier, which is an integral part of the design, is a simple approach that allows high actuationforces with shop air pressure. In the case of the High Force Pneumatic closer, air pressure is applied for grippingand is spring returned for releasing.The High force pneumatic closer design can be set for varying gripping force levels by simply adjusting theincoming air pressure within the specified operating range. The following closers will accommodate the completerange of Hardinge 5C tooling including step chucks and internal Sure-Grip systems.Pneumatic Fail-Safe Collet CloserThe Pneumatic Fail-Safe Collet Closer is spring-close, air-to-open for fail-safe operation. The part will remainclamped at an optimum 5C draw bar force of 1760 lbs (7829 N) even if loss of air occurs. To release the partpiece, apply max air pressure of 85 psi. A draw bar travel of .060" (1.5mm) allows varying part diameter of.015"(.4mm). The 1.08" (27.4mm) through-hole accommodates long parts and thru-coolant. The collet closeris designed so that the Indexer can be positioned vertically without any use of a spacer. Please contact HardingeInc. if you plan to replace one of our other closers with a Fail-Safe closer as older indexers may not accept theFail-Safe closer.CAUTION: Don't exceed 85 psi while operating Fail-Safe Collet Closer as it may cause fatal damage to the closerand may cause injury to the operator. Increasing air pressure will not aid in gripping of5Cpartpieceas grippingHighForceCloserforces come from internal springs.Force ChartPneumatic High Force Collet CloserDrawbar t No. BD -0009500-0119Air Pressure(psi)The Pneumatic High Force Collet Closer is designed with a dual cylinder for a10greater available gripping force. This force can be regulated by adjusting the air20pressure, but the force needs to be set according to levels below the maximum30allowed for the workholding system. Much like the Fail-Safe closer, the total40travel of this unit is .060" (1.5mm), but the through hole is only .312" (7.9mm).50This means that the high force closer can
