Drilling Operations
The alignment between the headstock and tailstock of the lathe enables you to drill holes that are precisely centered in a cylindrical piece of stock. I tried doing this once with my drill press and vise before I had the lathe; it did not turn out too well.
Before you drill into the end of a workpiece you should first face the end as described in the facing operations section. The next step is to start the drill hole using a center drill - a stiff, stubby drill with a short tip. If you try to drill a hole without first center drilling, the drill will almost certainly wander off center, producing a hole that is oversized and misaligned. We hate that!
Center drills come in various sizes such as #00, #0, #1 - #5, etc. You can purchase sets of #1-#5 for under $5.00 on sale from several suppliers.

Preparing to Drill
Before drilling you need to make sure that the drill chuck is firmly seated in the tailstock. With the chuck arbor loosely inserted in the tailstock bore, crank the tailstock bore out about 1/2". Lock the tailstock to the ways, then thrust the

    A useful feature your drill press might have is a XY table. Normally when you are working on a part, you need to be sure the piece is placed on the table in an exact location before you clamp it down. This is often difficult and takes several tried before you get it right. With an XY table, since the entire table is adjustable, you can clamp down the piece anywhere and then move the table into position. It is called an XY table because there are two wheels, on which moves it forward and backwards, and another…

    Jiambalvo Case 7-2 Five Star Tools

    This report provides an analysis and evaluation of constraints in the production process for the Model C210 and the Model D400 of the Five Star Tools product line. The significant growth the company has experienced in recent years has led to a strain on the firm’s production capacity. This report seeks to determine how to loosen constraints on production and identify the most profitable product line given current production limitations. Incremental analysis is used to determine both the benefit of one additional hour of production time in the coating and sharpening process and the incremental yearly profit associated with adding a new inspection station.…

    Hydraulic Fracturing

    The safety steps included in this process are aimed to protect water supplies to be used by the population and to assure that neither the fluid that will be pumped through the well, nor the oil or gas that will eventually be gathered enters in contact with the water sources designated for the human consumption. To comply with these regulations steel surface or intermediate casings are interleaved into the well to depths of between 1,000 and 4,000 feet. The space between these casing “strings” and the drilled hole (wellbore), called the annulus, and is filling up with cement. Once the cement has been set, the drilling continues from the bottom of the surface or intermediate cemented steel casing to the next depth. This process is repeated, using smaller steel casing each time, until the oil and gas-bearing reservoir is finally reached (generally 6,000 to 10,000 ft).…

    Jigs and Fixture

    Jigs r provided with tool guiding elements such as drill bushes.These direct the tool to the correct position on the w/p. Jigs are rarely clamped on the m/c table bcz it is necessary to move the jig on the table to align the various bushes in the jig with the m/c spindle. Fixture hold the w/p securely in the correct position with respect to the m/c during operation. There is sometimes a provision in the fixture for setting the tool with respect to the w/p, but the tool is not guided as in a jig. Fixture are often clamped to the m/c table. Elements of J&F(Locating,Clamping,Tool Guiding & Setting Elements ) Adv of J&F(Productivity,Interchageability,Skill Reduction,Cost Reduction) Limits & Fits Diff b/w high and low limit , is called tolerance(unilateral,bilateral). Classification of Fits (Running,Push,Press Fit,Force Fit) Cost Estimation(Matl,M/cing,Heat Treatment, Assembling Cost) Principles of Location (1 Location must be related to the dimensional rqmts stated on the components drawing 2) It is prefable to use a more accurately m/chined surface than a less accurate surface Location, 3) The w/p should be prevented from moving along and rotating around X,Y and Zaxes 4) Location sys should facilitate easy and quick loading and unloading of the w/p and aim at motion economy 5) Redundant Locators must be avoided 6) Location sys should positevely prevent wrong loading of the w/p by foolproofing. Locating Methods of Plane Surfaces 1 A reasonably flat suface can be located by 3 pins of equal height having spherical surfaces at the location points 2 A rough, uneven or tapered plane should be loacted by 3 adjustable location pins having spherical ends 3 Additional adjustable supports are neccesary to prevent vibrations or distortion of the w/p during m/c operation. The force for adjusting the supports should be kept minimum so that the w/p doesnot get dislocated or lifted from the location pins 4) A machined surface can be located by pads having flat…

    Parts of Lathe Machine

    A metal lathe or metalworking lathe is a large class of lathes designed for precisely machining relatively hard materials. They were originally designed to machine metals; however, with the advent of plastics and other materials, and with their inherent versatility, they are used in a wide range of applications, and a broad range of materials. In machining jargon, where the larger context is already understood, they are usually simply called lathes, or else referred to by more-specific subtype names (toolroom lathe, turret lathe, etc.). These rigid machine tools remove material from a rotating workpiece via the (typically linear) movements of various cutting tools, such as tool bits and drill bits.…

    Tool Wear And Failure Analysis

    Tool Wear and Failure Mode - Figures show the development of tool wear for Tool A and Tool B respectively at various cutting speeds; 50, 60 and 70m/min. It was found that the tool wear rate for Tool B grow gradually when compared with Tool A. All the drills experienced a premature failure under 1 minute of cutting time. As a result, fewer holes were produced when using Tool A. Tool A experienced breakage when direct drilling after the 2nd hole at cutting speed of 60m/min. At 70m/min, rapidly breakage occurred after drill the 1st hole. Unlike Tool A, Tool B exhibited a lower tool wear rate as shown in Figures. It can be seen that initially the flank wear grew steadily and increased as drilling continues. Non-uniform flank wear and micro chipping…
