Information of Tailstocks and Bench Centers

Posted on by

Tailstocks are used on lathes and other machine tools to support one end of the workpiece through contact with a live center or dead center. Bench centers are table top mounted units used to support a workpiece between two tailstocks during inspection. A tail stock is a cast iron assembly that can slide along and be locked in place, and is used to hold long work in place or to mount a drill chuck for drilling into the end of the work. There are two types of tailstocks: manual and pneumatic. Manual tailstock requires workmen to apply pressure. Pneumatic tailstocks are driven by machines. If tail stocks are used, a dead center (which is non-rotating) may be used to support the workpiece, alternatively, a live center may also be used. Lathes with cylindrical tailstocks that can rotate around a vertical axis are turret lathes. All lathes have a bench centers, which is a horizontal beam.

 

All tailstocks are Morse Taper #3. Bench centers are precision ground tapered cylinders with a 60ยบ pointed tip and a Morse Taper shaft. A tailstock handwheel is a wheel with a handle and is used to move the tail stock ram in and out of the tail stock casting. Tail stock ram is a piston-type shaft that can be moved in and out of the tail stock by turning the tail stock handwheel. It has a tapered internal bore to accept a #2 Morse Taper shank. A lathe may or may not have a stand (or legs), which sits on the floor and elevates the bench center to a working height. Some lathes are small and sit directly on a workbench or table, and do not have a stand. A bench center is an important lathe component and is available in various sizes according to the work piece requirements. An inspection accessory is necessary for various machine-works to check the efficiency of the work piece. Aligning tailstock includes mounting a small center drill in the tail stock, turning the bar between centers and measuring the diameter of bar, and putting a straight bar between centers. Bench centers are generally used for long work pieces. Tailstocks must be aligned with the spindle within .0005 before beginning drilling operations.

Applications

 

Tailstocks and bench centers are used in many applications in lathes. Drilling, reaming, center drilling and countersinking are performed on the lathe using tailstocks and bench centers. Tailstocks and bench centers should adhere to various standards specified by International Standards Organization (ISO).

Available Types of Nails

Posted on by

Nails come in an amazing variety of size and application range. They range in size from tiny panel pins needing gentle tapping with a small hammer to enormous ones used to affix railway lines to sleepers, which are driven home with sledge hammers. They are used extensively in industry, agriculture, construction, manufacturing, and home use. The common variety is found everywhere from supermarkets to hardware stores and are mostly made of mild steel wire, flattened on the one end and sharpened at the other – you know those objects that cause blue swollen thumbs and foul language? It is however the non-common variety that is so interesting. They can be made of hardened steel, brass or copper and may have decorative heads and grooved or ringed shanks and they are used from furniture upholstery to roof trussing to fixing horse shoes. Some are even – maybe inadvertently – used to flatten car tires or fixing iron rims to wooden wheels. Yes, they are common and sometimes even lowly, but they are also exalted.

 

They also have some amazing names. Consider: Cut clasp, slate, upholstery, clout, ring shank and bright ones among others. They can be driven home by a hammer or a pneumatic tool. Brad nails are more often than not applied with such a tool. The nails are clued together in a string and inserted into the pneumatic tool. The nails are then shot into board or other material using the tool. The heads of brad nails are designed to slightly counter sink and the ensuing hole is later filled with wood putty to conceal the nail. Specialist hardened steel nails used to penetrate concrete is often shot into a wall or roof using a special gun that fires nails rather than bullets. The gun fires blank.22 cartridges which propels the nail into the wall.

 

Clout nails are long, thin ones with a flat large head and are used to fix ceilings to the roof or thin metal to wood. The large head avoids the nail to pull through the material and act as a fastener. Upholstery nails are used for decorative purposes, particularly in the use of leather as a means of upholstery. These nail have large rounded heads which are either copper or brass plated. They are used close to one another so as to create a special luxurious and rustic effect. Clavos nails on the other hand are crafted from iron, are decorative and used mainly as a decorative fixture to rustic doors – think Henry the 8th and the doors to his castle.

 

Roofing nails used to fix corrugated iron to wooden trusses are long shank ones with a large head and fluted shaft, designed to have a lead washer attached. The fluted shaft prevents the nail from loosening in the wind and the washer acts as water proofing. The ones used for fixing asphalt tiles or shingles are also specially designed for the purpose, both with large flat heads. Drywall installation requires special skills and tools. Nails designed for dry walling have rings along the shaft that prevents the nail from pulling out of a dry wall. The heads of such nails are also indented. Picture nails or masonry nails are made of hardened steel and designed to penetrate brick and concrete. These nails are not intended to support heavy weights but pictures etc.

What Is an Air Filter Regulator?

Posted on by

Certain pneumatic equipment, such as air tools, valves and actuators, needs a specific pressure to work properly. If there is low pressure, the pneumatic equipment will fail to perform or even cease to function. If the pressure is too powerful, the seal may pop up, leading to leakage, and it may even damage the equipment if it bursts. Many reputable manufacturers choose compressors with an air filter regulator unit factory-installed, which helps to reduce pressure gauge issues.

 

Purpose

Pneumatic filters, used in many industrial operations, remove contaminating fragments. These filters protect pneumatic equipment from damage that may result from these impurities, which may consist of dirt particles and aerosol or water droplets. The filters also remove impurities resulting from residue from lubricants emanating from the compressor and dust or oil vapors. Some industries may require an even cleaner environment, and therefore use a secondary pneumatic filter, which helps in the removal of impurities as tiny as 50 nanometers.

 

Function

Air filter regulators protect and service the parts installed “downstream” in compressed-air systems. Whereas the air filter removes impurities from the pneumatic system, the regulator maintains and controls the specified air pressure required for smooth and efficient working of the pneumatic equipment on which the regulator is installed. A pneumatic filter is used to achieve a clean-room atmosphere in numerous industries, including aviation, agriculture and beverage and food packaging.

 

How It Works

Pneumatic filter regulators maintain the correct pressure going into the system. Even if there is an increase in the pressure emanating from the compressor tank, the device still regulates and maintains the specified pressure. This regulating device can only bleed the extra pressure that is above the required pressure. If the pressure is low, the device cannot compensate for the difference in the required amount of pressure. This air regulator has a built-in mechanism in the form of a release valve, which helps to let out the excess pressure and prevent damage to your equipment.

 

Warning

Failures due to pneumatic system errors are rare, but when they do occur, according to the Aircraft Owners and Pilots Association, they are usually disastrous. You should be aware of your pneumatically powered systems and recognize early signs of failure. These signs can be subtle, but proper maintenance of your equipment, ensuring that you install a backup system and maintaining current knowledge of pneumatic systems can help to reduce failures.

To accommodate a wide scope of work, the lathes came with a feature that allows you to easily adjust their speed. They also come in different sizes to be used in a wide range of applications.

 

Wood lathe: this is the simplest lathe machine that you will come across. As its name suggests, it’s designed for turning wood. Its main parts are: headstock, bed, tailstock, and tool rest. You need to note that you need special skills in order to accurately turn smooth curves.

 

Turret lathes: they are used for applying different types of operations on single work pieces. In addition to ensuring that you have excellent turns, they also ensure that you are able to work very fast as you don’t waste time removing and transferring the work piece to another machine.

 

Toolroom lathe: it’s a type of engine lathe that is designed for high precision work. The machine is usually used in tool and dies shops where custom parts and precision fixtures are produced.

 

Since it’s produced with special attention to smooth operation, spindle accuracy and precise alignment, the lathe is able to achieve better accuracy and precision than the standard lathe.

 

CNC lathe: its computer controlled and comes with a number of advantages such as powered axis drives, high speed repeatability, and feedback control. To use the lathe you only need to set it. The cool thing with it is that you don’t need special tools to achieve excellently curved contours.

 

Special duty lathes: they are used for special purposes such as heavy-duty production of identical parts. In most cases, the lathes are used to perform functions that can’t be performed by standard lathes. There are many types of these lathes with the common ones being: automatic, crankshaft, multispindle, brakedrum, and jeweler’s lathes.
