  • Drill Bushing Installation Data
    DRILL BUSHING INSTALLATION DATA Drill Bushing Installation Data Explained below are the basic steps to installing a drill bushing. Because there are many different situations that bushings are used in and many variables associated with the installation, no definite rules can substitute for the skill and judgment of the experienced tool-maker. If you have any questions about the proper use or installation of any of our products, please be free to contact our technical support team. Step 1 Step 2 Hole Drilling and Preparation Inserting The Bushing Drill hole using the 'jig boring data' (see next page) to determine Use an arbor press to press the bushing into the jig-plate the correct size of the hole also keeping in mind interference fits, whenever possible. If not, use some other method such as hole roundness, and alignment (see below). Always drill holes drawing the bushing into the jig-plate with two washers and a nut using a jig borer or reamer. Next lubricate the inside diameter of and bolt. A hammer should only be used if no other method is the mounting hole and the outside diameter of the bushing. possible, and never directly strike the bushing with the hammer; Lubrication is important because bushings that are installed use a block to take the blows of the hammer. Whichever method without lubrication may pick up metal and score the mounting is used be sure to maintain centerline perpendicularity, otherwise hole during installation. Lubricated bushings are also more easily inaccuracy may result in the production operation. removed with less chance of damaging the jig-plate.

  • DRILLING OPERATIONS Chucking the Drill Drilling Holes
    Drilling and Countersinking 83 DRILLING OPERATIONS Chucking the Drill WARNING Before installing or removing drill bits, countersinks, or other devices in an air motor, be sure that the air line to the motor is disconnected. Failure to observe this precaution can cause serious injury. Install proper drill in the motor and tighten with proper size chuck key. Be sure to center the drill in the chuck. Do not allow flutes to enter the chuck. Connect the air hose to the motor inlet fitting. 3. Start the drill motor and check the drill for wobble. The drill must run true, or an oversize hole will be made. Replace bent drills. Drilling Holes 1. Hold the motor firmly. Hold the drill at 90° angle to the surface, as shown in Fig. 4-7. Fig. 4-7. Square drill with work. 2. Start the hole by placing the point of the drill on the marked centerline. With the fingers, turn the chuck un- til an indentation is made. (Omit this step when drilling through a drill bushing or when a pilot hole ex- ists.) 84 Standard Aircraft Handbook Position thumb and forefinger to prevent the drill from going too far through the work, which can cause dam- age to items on the other side or result in an oversized hole. Drill the hole by starting the drill motor and exerting pressure on the centerline of the drill. Exert just enough pressure to start the drill cutting a fairly large size of chip and maintain this pressure until the drill starts to come through the work.

  • Machining of the Gill Corporation Composite Products
    Machining of The Gill Corporation Composite Products 1. Machining of The Gill Corporation Composite Products This guide contains recommendations for cutting, drilling, and routing of laminate and sandwich panels. The information can be useful for the fabrication of the semi-finished material into exact replacement articles. The laminates are composed of a fiberglass-reinforced/phenolic resin binder. While this is not particularly difficult to drill or cut, certain precautions and tools should be used to prevent delamination, tearing, singeing, or fuzzing of the reinforcing fibers/resin. The sandwich panels are composed of carbon fiber or fiberglass reinforced/phenolic resin facings bonded to Nomex/ phenolic resin honeycomb core. Care must be taken in the fabrication of replacement panels to avoid disbonding, delamination, tearing, singeing, fuzzing of the fiber, or crushing of the core. 1.1 Drilling 1.1.1 Tooling Recommendations for Drilling Drill Type Information High Speed Steel Lowest initial cost, readily available. Short drill life, especially in fiberglass. About 500 holes in fiberglass between sharpening. Improved with a hard flash of chrome plating (0.003" - 0.005") is put on the drill bit. Flash chrome is recommended for large drills where carbide is too expensive. Tungsten Carbide Higher initial cost but longer life. May be re-sharpened. Up to 3/16" diameter, grind drill to have a slight negative rake on the cutting tip. Over 3/16" diameter, use slow helix dill, ground to 55° point (sharp). Recommended for high production requirements only. Diamond-Grit For fiberglass only. Most expensive, but longest lasting, fastest and smoothest cutting. Edged Drills Recommended for high volume only.
