Introduction 1. This instruction manual describes the swing lock chuck H063M and H064M (standard model). 2. Please read this manual carefully and fully understand the procedures for installation, operation, inspection, and maintenance before operating the chuck. 3. Ignoring any instructions in this manual may result in a serious accident or machine damage, leading to injury to the operator or personnel near the machine.
Safety Precautions The following precautions apply to handling, maintenance, and operation of the chuck. Read and understand them carefully before use. DANGER Never operate the rotating cylinder selector valve while the spindle is rotating. Otherwise, the gripped work piece may come off and fly out. Never put any part of your body inside the spindle cover while the spindle is rotating.

(supplied from ExxonMobil) For all the chuck parts including consumables, place an order with Howa Machinery, Ltd. Howa shall not be liable for any accidents caused by use of parts not supplied from Howa. Any and all warranties are invalid unless only Howa’s genuine parts are used.
1. Construction and Operation 1.1 Model Coding The swing lock chuck H063M and H064M are model coded as follows: 3- jaw type H063M JIS-specified spindle nose No. No mark: : : : Having a straight socket for installation of chuck.
2. Installation 2.1 Unpacking Take the chuck out of the package box. At this time, be careful not to take out or lift it by hands. This is because 8-inch or larger chucks weigh over 20 kg, and lifting such a heavy chuck may cause damage to your lumbar or injury by dropping the chuck.
2.6 Installing Procedure Fig.3 2.6.1 Before Installation After taking the chuck out of the package box, wipe off all anticorrosive oil clinging to it with a cloth permeated with cleaning oil. 2.6.2 Installing Chuck Adapter Install the chuck adapter on the spindle end face. Then the chuck installing socket (C) and datum face should be machined in place.

(4) Insert the Hex. key spanner equipped from the front side of the chuck and check to see whether the draw screw can be turned. (5) Hoist the chuck with the chain block and screw in the draw screw into the connecting rod until it can be tightened no more.
2.6.4 Inspection Operational resistance develops when there is some abnormality in the installation procedure. If the chuck is used without removal of the resistance, parts seizure or abnormal wear may occur, causing marked shortening of service life. Once the installation has been completed, be sure to check out the minimum operating pressure.
For all the chuck parts including consumables, place an order with WARNING Howa Machinery, Ltd. Howa shall not be liable for any accidents caused by use of parts not supplied from Howa. Any and all warranties are invalid unless only Howa’s genuine parts are used.
Use exact torque for fastening bolts. WARNING If less torque is used than specified in Table 7 above, the bolts may loosen in the top jaws and/or the work piece could come off. If the torque is greater than the specified value, the locker arms and/or top jaws will deform and defective operation will result, leading to breakage and release of the top jaws and/or work piece.

Do not grip near the end of the jaw stroke. WARNING Forged or molded work pieces have surface irregularity as far as they are not machined. The chuck may not be able to grip such a work piece in a stable state. Gripping a forged or molded work piece, not machined, near the end of the jaw stroke will cause insufficient gripping force, and the application of the tool to the work piece may cause the work piece to slip out of the jaws and fly off.
As for H063M model, when machining the standard top jaws as top CAUTION jaws, remove the adjacent corners inside as they may interfere. (See Section 6.4 "Standard Soft Jaws".) Depending on the shape of the top jaws, it may be necessary to...
Fig. 15 (2) After choosing work piece gripping position, determine the top jaw shape so that the parts besides the gripper should not contact with the work piece. The gripper installation surface should be cylindrical having inside diameter of gripping diameter (φA) and dimension B (Table 11) added.
3.7 Setting Working Conditions The chuck using conditions includes not only cutting force but also many factors such as cutting force, work gripping length, work protruding length, friction coefficient, and rotational speed. In order to determine the ideal working conditions, all of these factors must be given due consideration, with considerable time necessary to perform the calculations.
3.8 Precautions for Operation We are the chuck manufacturer, and are not responsible for the safe operation of the combined chuck and lathe or machining center into which the chuck is installed. There exist numerous rules and guides for overall safe operation among the most respected is ANSI B11.6- 1984. Nonetheless, while reference may be made to ANSI and/or specifications, mere mechanical compliance with ANSI and/or other standards does not ensure safety.
3.8.2 When Gripping Work piece When gripping the work piece with the chuck, be careful not to get CAUTION any part of your body caught between the top jaws and the work piece or between the work piece and the machine. The operator's hand may be injured.
3.8.4 End of Operations Remove the work piece from the chuck at the end of operations. If WARNING the work piece is left gripped in the chuck, the cylinder supply pressure may decrease, or the work piece may fall oft due to mistaken operations, it may cause severe personal injury and machine damage.
4.2 Disassembly and Cleaning Even with proper lubrication, fine chips or scale can enter the chuck to jam the area of the jaw guide or wedge plunger, thus preventing smooth operation. Disassembly and cleaning must be done on a regular basis every 1000 hours. When doing so, inspect carefully for parts wear and breakage, replacing as necessary.

4.3 Setting Safe Rotational Speed ANSI B 11.6-1984 section 7. 1. 9 suggests guidelines for setting a safe rotational speed. A safe rotational speed will be a function of the consideration of among other things, the degree of wear and tear then existing on the jaws of the chuck, which may effect their ability to grip the work piece.
