Introduction 1. This instruction manual describes the I.D. draw down power chuck H013MC (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.

Howa. Any and all warranties are invalid unless only Howa’s genuine parts are used. The H013MC chuck cannot grip the outside diameter of the work piece. Gripping the outside diameter will cause poor gripping accuracy and insufficient gripping force. This, in turn, may cause the work piece to fly off and may cause severe personal injury or death to the operator or bystanders.
1. Construction and Operation 1.1 Model Coding The draw down power chuck H013MC are model coded as follows. 3- jaw type I.D. draw down power chuck ( This chuck cannot grip the outside diameter of the work piece. ) H013MC JIS-specified spindle nose No.
2.3 Preparations for Installation Except the direct-mount chuck of A type, a chuck adapter is needed to install the chuck onto the lathe spindle. Contact us if you need information on how to design a chuck adapter. In addition to the chuck adapter, a rotating cylinder, a cylinder adapter, a connecting rod, and either a hydraulic or pneumatic pressure source are required to operate the chuck.

If the dimension Re is less than that indicated in Table 1, the chuck CAUTION cannot be installed. Table1 Chuck size Re±1 (mm) 27.5 32.5 36.5 36.5 Fig. 4 Adjust the screw depth of the connecting rod (Re) to a proper WARNING length.
Fasten the chuck installing bolts with recommended tightening WARNING torque. If the torque is largely different from the recommended value, lower or higher, the bolts may break and the chuck and/or work piece may fall out; this presents a hazard that may cause severe personal injury or death to the operator or bystanders.
Howa. For all the chuck parts including consumables, place an order with WARNING Howa Machinery, Ltd. Howa assumes no responsibility for accidents caused by use of the parts not prepared by Howa. Any and all warranties are void unless only Howa genuine parts are used.

Forming plug for H013MC chuck Fig.11 Table 8 Chuck size S1 (mm) S2 (mm) S6 (mm) S7 (mm) 3.4 Installing Stopper The draw down chuck cannot grip stably if the work piece is not positioned in the chuck's axial turning direction. To position the work piece here, the work piece must be pushed to the chuck's work face.
3.5.1 Permissible Cylinder Force The permissible cylinder force indicated in the specification table or catalogue is the maximum cylinder force at which the chuck will not suffer damage, presuming those standard soft jaws or standard hardened jaws are used. This maximum force may be used as required, of course, but ordinarily long-term use under conditions of maximum force is not recommended.
To comply with ANSl B11.6-1984 section 4.3.2, you need to install a WARNING check valve and an accumulator in the connecting area with the chuck so that the hydraulic or pneumatic system does not loose pressure in case of failure. Besides check valve and accumulator, it is essential to install a shielding cover that separates the chuck and work piece from the operator or bystanders.
Severe personal injury may result if the operator mistakenly comes WARNING into contact with a spinning chuck whose top jaws or gripped work piece have irregular contours which are not readily visible while rotating. A door or guard must be provided to prevent anyone from approaching the spinning chuck.
Fig.13 4.2 Lubricating point and procedure Lubricating point and process execute with following procedure. In each of these models, four grease nipples are furnished on the outer surface of chuck body. Lubrication should be done when the jaws are opened position.
4.4 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.
