Its name is derived from the fact that early machine tools were driven by separate Engines or central engine with overhead belt and shafts.

About me, My name is Amrit Kumar. I have studied Mechanical Engineering and on this platform, I try to share the content in detail and in a good format. My aim is to provide useful and engaging content to our readers. I have been on this journey since 2016.

The turret usually accommodates 6 tools for different operations like drilling, countersinking, reaming, tapping, etc, which can be brought into successively working positions by indexing the turret.

The bed consists of heavy metal slides running lengthwise, with ways or v’s forced upon them. It is rigidly supported by cross griths.

Drilling operation is a type of machining operation which is used to remove the material from the workpiece by making use of drill bit, which is held stationary in the Tailstock. Finally creating a hole in the work piece.

Drilling into concrete isn’t a DIY task for beginners. If you’ve read this guide on how to drill through concrete and don’t feel confident or comfortable using a hammer drill or rotary hammer, or if you don’t feel like you are strong enough to power through and bore a hole with the tool, it might be best to ask a professional to complete the project for you. Other reasons why you may want to call a professional include:

It supports the main spindle in the bearing and align it properly. It also houses a necessary transmission mechanism with speed changing levers to obtain different speeds.

A lathe machine is a machine tool which removes the undesired material from a rotating workpiece in the form of chips with the help of a tool which is traversed across the work and can be feed deep into the work.

Nowadays, Lathe Machine has become a general-purpose machine tool, employed in production and repair work, because it permits a large variety of operations to be performed on it.

This design was further improved by the Ancient Romans who added the turning bow and lather the paddle (as there in the sewing machine) was added.

The scrapped or the ground guiding along with the sliding surfaces on the lathe bed ensure the accuracy of the alignment of these three units.

Facing is frequently the first operation performed in the production of the workpiece and often the last. We can relate it to the phrase” ending-up”, which will help us in remembering its sequence.

No, you need to drill a pilot hole into the concrete before driving a screw that’s rated for concrete like Spax #10 multi-material screw into the hole.

The tools that work best for drilling into concrete are rotary hammers and hammer drills. Rotary hammers are weighted to provide the power that’s needed to make either small holes or larger holes, and hammer drills are used to make smaller holes. If this is a rare situation and you don’t expect to need to drill into concrete often, you can rent both types of tools at a local home improvement center.

iv)Saves Money: Lathe machine helps in reducing the cost of machining because less operators are required for machining.

The normal cutting operations are performed with the cutting tool fed either parallel or at right angles to the axis of the work.

Keep reading to find out how to drill into concrete walls or floors, and learn what you need to know about selecting and using the right tool for the job so you can achieve your home improvement goals.

Special purpose lathe machine is used for performing the specific special tasks which cannot be performed by ordinary lathe. Some type of special purpose Lathe are as follow:

The operations which can be performed by the Engine Lathe machine are Turning, facing, grooving, knurling, threading, and many more operations can be performed by it.

No. You can’t use a regular drill for concrete. Choose a hammer drill or a rotary hammer. They have impact energy in addition to rotational energy. The impact energy pulverizes the concrete at the tip of the bit while the rotational energy draws the dust out of the hole through the bit’s flutes.

Facing is a process in which the end of the workpiece is being machined by the tool which is at a right angle to the axis of the rotation of the workpiece.

Turning is a machining operation in which the diameter of the workpiece is being reduced by removing the excess material from the outer diameter of the job(workpiece) which is mostly cylindrical or conical in shape.

It is used for irregular shapes, rough castings of square or octagonal in such jobs, where a hole is to be positioned off the center.

Lathemachine

There isn’t a trick to drilling into concrete. It’s important to use the right tools—rotary hammer or hammer drill—and the right bits that are made for concrete.

Any taper angle can be produced by this method and both internal and external taper turning operations can be performed by this method.

So rotation of the job is obtained by the chuck and the desired linear motion of the tool-post(asthe lead screw drives the saddle when it is engaged) is provided with the help of lead screw.

Parting is operation in which the deep groves are being made on the parent material to remove the specific portion from the parent material resulting in dividing the workpiece into two or more parts.

Lathe Machine is known as one of the oldest machine tools in the production machine. This Machine is also known as the mother of all machines.

In this one person would turn the wood workpiece using rope and the other person would shape the workpiece using a sharp tool.

Formtool method is a type of method in which the shape of the tool is same as that the shape of the component to be produced.

Cross slide is provided with a female dovetail on one side and assembled on the top of the saddle with its male dovetail.

Put on your safety protection before you begin to drill. Then, get into position to drill by planting your feet firmly on the ground, shoulder-width apart. Hold the drill securely with both hands: Grip it in one hand like a handgun, and, if there’s no auxiliary handle for your spare hand, use that hand to brace the back of the rotary hammer or hammer drill while making a hole.

Compound rest is present on the top of the cross slide. It supports the tool post and cutting tool in its various positions.

iii) Saves time:Lathe machine because of its extensive high speed and high accuracy saves a lot of time, resulting in the increased production.

The process of making the surface of the work piece rough by embossing(impressing) a diamond shaped regular pattern on the surface by making use of a knurling tool is called as knurling operation.

Nuts, bolts, piston, Ram, pump part, electric motor parts, sleeves, Air craft parts, gun barrels, candlesticks, train parts, cue sticks, wooden bowls, baseball bat, crankshaft and many more things.

Continue to operate the drill with a steady, light-but-firm touch so you’re never forcing it in. It’s critical to control the drill so it doesn’t run away once you begin work. When you lean in to bore the hole, the drill bit should be perfectly perpendicular to the concrete. Be prepared for some recoil from the drill’s hammer action. Concrete can have air pockets and pebbles that can make resistance unpredictable, with the result that it can be disturbingly easy to lose control of the tool for a moment.

Feed rod is a power transmission mechanism used for precise linear movement of the carriage along the longitudinal axis of the lathe.

The holders rest on a wedge which is shaped on the bottom to fit into a concave-shaped ring(segmental type), which permits the height of the cutting edge to be adjusted by tilting the tool.

Thread cutting is a type of operation in which the threads are being cut on the internal and the outer surface of the workpiece as per the requirement.

It consists of the dead centers, the adjusting screws and the handwheel. The body of the tailstock is adjustable on the base which is mounted on the guideways of the bed and can be moved to and fro.

T- Lathe machine is a type of machine which has T shaped bed and is used in the aerospace industry for the machining of the rotors of the jet engine.

As we know for threading operation requires rotational movement of the job (work piece) and the linear movement of the tool (tool post).

Metal working operations, metal spinning, thermal spraying, in automobile industry mainly in the crankshaft, wood turning, Glass turning operation, for forming screw threads, also used for reclamation of the parts, and many more…

Wheel lathes is special purpose lathe machine which is used for finishing the journals and turning the tread on locomotive wheels.

In taper turning attachment method the slide ways are tilted by an angle equal to the taper angle of the component so that the saddle is automatically tilted and when the saddle is moving on the slide ways it produce tapered component.

“Drilling into concrete means hard surface (concrete) meets harder surface (drill bit) with rotation force added. The result is that once the bit starts to twist it’ll “skate” off the desired hole location. The fix is easy. Once I mark the the hole location, I take my nail set…and give it a tap or two with my hammer. This creates a small hollow the bit can ride in to get started.”

Mark the desired position of the holes in pencil on the concrete surface, and double-check the locations before you proceed. If your drill’s features include a stop bar, set it to the exact depth you want by following the drill manufacturer’s specifications. No stop-bar feature? Instead, wrap a piece of tape around the drill bit to show you where to stop.

Remove any artwork from the concrete wall and any furniture that’s below the desired hole location. Place a drop cloth below to collect debris as you bore into the wall. Make sure you have ample space to drill and that you have a stable surface on which to stand.

The workpiece is held between two rigid and strong supports called center or in a chuck or in face plate which revolves.

Bench Lathe machine is a type of small lathe machine which has all the parts of the engine Lathe machine and speed lathe machine.

Boring is an internal turning operation used for enlarging the existing holes by some amount. It can further be divided as:

Lathe machine is probably the oldest machine tool know to mankind. Its first use dates back to 1300 BC in Egypt. The first lathe was a simple Lathe which is now called a two-person lathe.

In it, the several tools are set up on a revolving turret to facilitate in performing a large number of operations on a job with minimum wastage of time.

As the name suggest automatic Lathe machine is machine in which the complete work and the job handling movements required for the completion of the job is done automatically.

It consists of three jaws which move simultaneously by turning a key and the workpiece automatically remains in the centerof the chuck opening.

Milling machine

In these articles we will try to learn Definition, Parts, Operation we perform on it, The Types, Specification advantages, disadvantages, and application of lathe machine.

Carriage is located between headstock and tailstock. The basic function of the carriage is to support, guide and feed the tool against the job during operation.

Apron consists of the gears and clutches for transmitting motion from the feed rod to the carriage, and the split nut which engages with the lead screw during cutting threads.

CNC machine

Many hammer drills offer only two speeds, so turn your drill on at the slower speed for best control when making the guide hole. If your drill has only one speed, then work in short, controlled bursts of a few seconds each until you’ve established a hole.

Tip: If you hit obstructions, never force the drill farther into the concrete. This can damage the bits or drill, or cause you to lose control of the drill and mess up your hole, damage the concrete surface, or worse.

Drilling into concrete also requires the right bit. Choose the appropriate tungsten carbide masonry drill bit for your desired hole size and your hammer drill or rotary hammer. Unlike wood drill bits, rotary hammer bits are fluted along the shank so they can travel up and down like a jackhammer while working through the concrete to make the hole you need.

Lathing

If you’re feeling confident, turn the speed to full, keeping a firm grip on the tool with both hands, and drill into the concrete until the hole is complete. Periodically pull the drill out to brush away concrete dust. You can expect to bore a 2-inch hole in under a minute using a hammer drill, pausing every 15 to 20 seconds to clean out the debris.

Tail stock is a movable casting located opposite to the headstock on the way of the bed. The basic function of the tailstock is:

In gap bed lathe, gap is provided over the bed near the headstock to handle the job having flanges or some other protruding parts.

Once you have drilled your hole to the necessary depth, blow all of the concrete dust out of the hole with a can of compressed air. Then vacuum up whatever has fallen to the ground. You should still be wearing your goggles throughout this process to protect against any concrete dust and shards that might fly in your face and scratch your eyes.

Further during the industrial revolution Steam Engines and water wheel were attached to the Lathe to turn the workpiece to a higher speed which made the work faster and easier.

From this crude begging and over a period of more than two centuries, the modern engine lathe has evolved. Now we have the most advanced form of the Lathe Machine which is the CNC Lathe Machine.

In this method the tailstock is moved from its middle position to one side of the bed, which makes the workpiece tilted with respect to the lathe axis and feed.

Whether you want to secure shelves in your garage, hang artwork on an interior concrete wall, or frame walls in your basement, drilling holes in concrete is possible with the right tools and bits. While there is more than one tool that can drill a hole into concrete, the best tool for the job depends on the size of hole that you need.

Before drilling into concrete, make sure to have on hand safety glasses, ear protection, and gloves to wear while working. Because it’s a dense and porous material, concrete can chip and the bit can become very hot while drilling into it. Drilling into concrete also can be very loud.

Lathe removes the undesired material from a rotating workpiece in the form of chips with the help of a tool which is transverse across the work and can be fed deep in the work.

There are light-duty and heavy-duty tools that can drill into concrete. Tools that are considered heavy-duty weigh more and are used for creating holes that are larger than ½ inch in diameter. For most DIYers, drilling into concrete means making small holes for setting wall anchors or for driving screws. A ⅞-inch rotary hammer or a hammer drill is designed for these applications. Choose a 1-inch rotary hammer for making larger holes.
