A. DEFINITION DRILL MACHINE
Drilling machine is a type of machine cutting tools rotating movement which direction the drill bit feeds only on the machine axis (the construction of perforation). While drilling is an operation to produce a round hole in the piece-work by using a rotating cutter called a drill.
B. TYPES OF DRILL MACHINE
1. Drilling table machine
Drilling machine drilling machine table is placed on the table. This machine is used to make holes work pieces with small sizes (limited up to size 16 mm). The working principle is a round table drilling machine electric motor transmitted to the crankshaft so that the shaft rotates. Furthermore, the shaft rotates at the same time as the drill bit holder can be moved up and down with the help of straight gears and gear rack that can manage feeds pressure when drilling.
2. Hand drill machine (gun)
Hand drilling machine drilling machine which is operated by hand and looks like a gun. Hand drill machine usually is used for punching holes in wood, walls and metal plates. Unique drilling appliance is accustomed to create pockets can be accustomed to make tighter mounting bolts plus take out the particular mounting bolts given it includes TWO converts belonging to the proper plus eventually left.. Drilling machine is available in various sizes, shapes, capacity and also their respective functions. One example is a hand drill from Makita LCT300W.
3. Radial drilling machine
Radial drilling machine specifically designed for drilling objects are large and heavy work. This machine is directly mounted on the floor, while the machine table is permanently installed in the foundation or the base engine. On this machine the work piece does not move. To achieve the drilling process of the work piece, the main axis which is shifted to the right and left and can be moved up and down through the rotation of threaded rod.
4. Upright Drilling Machine (Vertical Drilling Machine)
Used to work on work pieces with larger sizes, where the process feeds from the drill bit can be controlled automatically up and down. In the process of drilling, the main shaft is driven up and down as needed. Table can be rotated 3600, his desk was tied together with threaded on the rod axis machine, so the desk can be moved up and down by moving the crank.
5. Coordinate drilling machine
Coordinate drilling machine is basically the same principle with other drilling machine. The difference found in the drilling position control system. Coordinate drilling machine used to create / enlarge the hole with the center point and diameter distance between each hole has a size and high accuracy. To obtain high accuracy measure is used desk combination that can be arranged in longitudinal direction and transverse direction with the help of an optical system. Accuracy and precision of the size of the optical system can be set up to achieve tolerance of 0.001 mm.
6. Drill floor
Drilling machine drilling machine floor is mounted on the floor. Terrain drilling appliance drilling appliance also referred to as your column.. Another type drilling machine drilling machine floor is a desk propped up by the supporting rod. Drilling appliance on this style will likely be suitable for the particular drilling with materials huge plus serious operate..
7. Drilling machine pivot
This drilling machine has more than one spindle, usually a table with four spindles. This machine is used to perform multiple operations at once, so much faster for mass production, there are 20 or more spindle with a drive head.
C. SECTION – THE MAIN ENGINE DRILL
1. Base (holder)
Base is a sustainer of all components of the drilling machine. Base is located at the bottom attached to the floor, usually bolted. This setting up should be formidable since it can have an effect on this reliability on the drilling derive from this vibrations of which happen..
2. Column (Pillar)
Part of the drilling machine used to prop up the parts that are used for the drilling process. Cylinder-shaped tips which may have your groove or maybe track towards the directory motions avenue belonging to the worktable..
3. Table (Table)
Parts used to put the work piece to be drilled. Desk can be adjusted vertically to accommodate different heights or work that can rotate to the left and right with the axis of the shaft on the end attached to the pillar (column). For the ring-shaped table can be rotated 3600 with the shaft in the middle of the table. All of them equipped with lock (table clamp) to keep the position in accordance with the required table. To clamp the work piece to be quiet to use vise is placed on the table.
4. Drill
It is a hole or groove maker efficient. The drill is most commonly used is a spiral drill because the power of a good shipping, distribution flakes (furious) is good because the flow screw-shaped grooves, corners and field lucrative slice cut may be sharpened without changing the diameter of the drill. The fields are not radial spiral drill cut but shifted so as to form lines tangent to the small circle which is the heart drill.
5. Spindle
The part that moves chuck, which holds / gripping the drill bit.
6. Spindle head
Is home from the construction-driven spindle motor with a belt connection and regulated by the drill feed pemakanannya handle to the process.
7. Feed Drill Handle
Handel to reduce or emphasize the spindle and the drill bit into the work piece (feed)
8. Electrical
Prime mover of the drilling machine is an electric motor, for completeness ranging from power cables and connecting cables, fuse / fuse, indicator lights, switch on / off switch and speed control switch.
D. MUG DRILLING
Types of cutting tools (drill) used in the drilling process, among others:
1. Drilling
The process used to make a hole in a solid work piece.
2. Step drill
The process used for making holes with a diameter of bunk.
3. Reaming
Reaming is how accurate fitting and finishing existing holes.
4. Boring
Process of enlarging an existing hole with a chisel point. Boring is preferred because we can fix the hole size, or alignment and could result in a smooth hole.
5. Counter Bore
This operation uses a pilot to guide the cutting action. Used to end a hole enlargement process has been created with a certain depth, to accommodate the bolt head.
6. Countersink (drill under)
7. Exclusive sloping conical increase afre the wedding from the twist openings for versink.. Cone angle 60 °, 82 °, 90 °, 100 °, 110 °, 120 °
8. Tapping
Tapping is the process by which form the thread. This is done either by hand or by machine.
To work on drilling process mechanism is as follows;
- Objects Installation Work
a. If using a vise, for flat and horizontal work piece with the thickness of the object size shorter than the height size of the mouth vise, at the bottom of the work piece held by bearing a flat and parallel (parallel). In order not helped move vise, vise bound by using the nut screws on drill table.
b. If not using a vise, work piece fastened to the drill table uses two bolts nuts, two U-shape clamps with two retaining blocks accordingly.
c. To drill a round metal rod, the work piece is placed on a girder stems V and clamped with a special binder, and then detained by using the appropriate beam by the nuts and bolts tied to the drilling machine table.
d. With the wood for being drilled by way of, the job item can be clamped with the fishing rod, unique clamps, grin keeping the right elevation plus mounted using fanatic bolt fastener in order to never problems the particular vise..
2. Installation of Drilling on the chuck
a. Drill with straight shaft (taper) directly entered on-axis hole drilling machine, may not use the drill holder. So, that pin groove acquiring conclude in the taper in addition to taper pin counteract through one particular pin which standardised (normalized).. Edge taper is not used to hold but to ease off from its place by using a socket. Before removing the drill, a piece of wood should be placed underneath, so that the drill will not be damaged when they expire.
b. Drilling with a stalk cylinder used “drill holder to concentrate its own” with two or three jaws. Drilling must be inserted as deep as possible so as not to skid when turning. Inner surface of the holder relating to the drill stem, resulting in a round drill.
c. Drill with a round head straight utilized holder / clamp automatic drilling (universal), which when played the key, then the mouth will open or clamped by it (automatic).
d. Drill with tapered head taper or gloves used deduction made in accordance with the levels and needs, so there are a variety of sizes.
e. A good drill to drill shavings eye piece well and will produce the same thick shavings with an exit through both drill spiral grooves. Pertaining to elements demanding refrigeration, utilized a unique copper tea pot the location where the customizable stuff..
3. Adjust the position of the work piece by moving the table, for the vertical direction is turning the handle, to move the locking swivel desk is open under the table and adjusted, then do not forget to lock all the locks.
4. Plug the machine into the mains socket, and then press the switch on (at this time the spindle is spinning). Adjust speed to suit work piece.
5. For feeds into the work piece, turn the Handle Drill feeds so that the drill down and eat the work piece.
6. Use coolant if necessary
7. When finished, press the switch off to turn off the engine
8. For hand drill machine / gun special switches to the choice of rotation to the right and left.
E. MACHINE MAINTENANCE
A machine in maintaining the performance of its performance also requires intensive care at every engine component. It is also necessary for the drilling machine. The things that must be considered:
1. Lubrication on a regular basis to remove heat and friction.
2. Machinery should be cleaned after use
3. Chips should be cleaned using a brush.
4. T-slots, grooves, spindles sleeves, belts, along with pulleys have to be cleansed..
5. Oiled machine with anti-corrosive fluid to prevent it from rusting
6. Be sure to walk straight cutter (stable) before starting operation.
7. Do not place other equipment on the drilling table
8. Avoid loose clothing
9. Special protection for the eyes
Drill is not only necessary force alone but also much-needed expertise, perseverance and patience to produce the best. But you also need to remember that the drill bit you use is also contributing to the ease of drilling and the results. Use LCT300W in order to facilitate your Makita in the work to drill and produce satisfactory results.
Hopefully the above explanation can add to your insight in the problem to drill.
