Types of drilling machines?
Basic Types of Drilling MachinesDrilling machines or drill presses are one of the most common machines found in the machine shop. A drill press is a machine thatturns and advances a rotary tool into a workpiece. The drill press is used primarily for drilling holes, but when used with the proper tooling, it can be used for a number of machining operations. The most common machining operations performed on a drill press are drilling, reaming, tapping, counterboring, countersinking, and spotfacing.There are many different types or configurations of drilling machines, but most drilling machines will fall into four broad categories: upright sensitive, upright, radial, and special purpose.UPRIGHT SENSITIVE DRILL PRESSFigure 1 Upright sensitive drill pressThe upright sensitive drill press (Figure 1) is a light-duty type of drilling machine that normally incorporates a belt drive spindle head. This machine is generally used for moderate-to-light duty work. The upright sensitive drill press gets its name due to the fact that the machine can only be hand fed. Hand feeding the tool into the workpiece allows the operator to "feel" the cutting action of the tool. The sensitive drill press is manufactured in a floor style or a bench style.UPRIGHT DRILL PRESSThe upright drill press (Figure 2) is a heavy duty type of drilling machine normally incorporating a geared drive spindle head. This type of drilling machine is used on large hole-producing operations that typically involve larger or heavier parts. The upright drill press allows the operator to hand feed or power feed the tool into the workpiece. The power feed mechanism automatically advances the tool into the workpiece. Some types of upright drill presses are also manufactured with automatic table-raising mechanisms.Figure 2 Upright drill pressRADIAL ARM DRILL PRESSThe radial arm drill press (Figure 3) is the hole producing work horse of the machine shop. The press is commonly refered to as a radial drill press. The radial arm drill press allows the operator to position the spindle directly over the workpiece rather than move the workpiece to the tool. The design of the radial drill press gives it a great deal of versatility, especially on parts too large to position easily. Radial drills offer power feed on the spindle, as well as an automatic mechanism to raise or lower the radial arm. The wheel head, which is located on the radial arm, can also be traversed along the arm, giving the machine added ease of use as well as versatility. Radial arm drill presses can be equipped with a trunion table or tilting table. This gives the operator the ability to drill intersecting or angular holes in one setup.Figure 3 Radial arm drill pressSPECIAL PURPOSE DRILL MACHINESThere are a number of types of special purpose drilling machines. The purposes of these types of drilling machines vary. Special purpose drilling machines include machines capable of drilling 20 holes at once or drilling holes as small as 0.01 of an inch.Gang Drilling MachinesFigure 4 Gang drill pressThe gang style drilling machine (Figure 4) or gang drill press has several work heads positioned over a single table. This type of drill press is used when successive operations are to be done. For instance, the first head may be used to spot drill. The second head may be used to tap drill. The third head may be used, along with a tapping head, to tap the hole. The fourth head may be used to chamfer.Multiple Spindle Drilling MachineThe multiple spindle drilling machine is commonly refered to as a multispindle drill press. This special purpose drill press has many spindles connected to one main work head (Figure 5).All of the spindles are fed into the workpiece at the same time. This type of drilling machine is especially useful when you have a large number of parts with many holes located close together.Figure 5 Multispindle drill pressMicro-Drill PressThe micro drill press is an extremely accurate, high spindle speed drill press. The micro drill press is typically very small (Figure 6) and is only capable of handling very small parts. Many micro drill presses are manufactured as bench top models. They are equipped with chucks capable of holding very small drilling tools.Figure 6 Micro drill pressTurret Type Drilling MachineTurret drilling machines are equipped with several drilling heads mounted on a turret (Figure 6). Each turret head can be equipped with a different type of cutting tool. The turret allows the needed tool to be quickly indexed into position. Modern turret type drilling machines are computer-controlled so that the table can be quickly and accurately positioned.Figure 6 CNC turret type drilling machine
How much drill press coast?
Anywhere from $79 for a small benchtop model to over $500 for a good workshop floor model. Professional ones much higher.
How do you revive people on Dead Rising 2?
Get an item of food in your hand, and go over to them. A prompt should appear, so press the button it tells you to press.
What are the advantages of using a hand saw over a table saw?
The advantages of using a hand saw over a table saw tend to be more of a personal preference. Many believe the table saws to have more advantages but the one advantage of a hand saw is the accuracy of the cut.
What was the advantages of the cotton gin over cleaning cotton by hand?
Advantage of the cotton gin was to speed up and have a more efficient production of cotton.
What is the advantage of grasping hand?
The ability of humans (and some animals) to close our hand or hands around an object means we can exert greater control over our environment. We can pick up and eat food. We can raise objects in a hand, carry objects, throw them, etc.
Can you name an advantage that the scanning of patterns in the human iris has over a hand-written signature?
A signature can be forged much more easily than an iris scan
What is iron drill bits?
I have worked with tools over 40 years and never seen an iron drill bit. Most common drill bits are HSS -High Speed Steel.
