How Does a Surface Grinder Work?

Posted on by

Basics

A surface grinder is a device that is used to accurately and intricately remove unneeded layers from a surface in an effort to smooth the target layer. The reason that a surface grinder is used is that it provides a great level of accuracy and detail that is sometimes difficult to achieve by hand. The use of a surface grinder is concentrated in heavy industry, especially in the automotive industry. Surface grinders are used on various types of metal and woods. The surface being worked on is directly related to the blade being used as they are specialized for different surfaces. This is a better option than trying to grind a surface by hand as it is less time consuming.

 

The amount of time it takes to grind a surface depends on the skill of the user and the surface being ground. The best safety guideline with a surface grinder is to take your time. Most accidents happen by using the wrong blade with the wrong material or running the blade on the grinder faster than the speed it was meant to run at. A surface grinder can be used to prepare surfaces such as floors and sheet metal for cars.

 

How It Works

The typical surface grinder has a table that is capable of moving forward and backward as well as side to side. When moving side to side, the table uses hydraulics to move. The machine also has a grinding wheel that rotates and has an adjustable height. The grinding wheel is generally made of diamond, aluminum oxide, silicon carbide or cubic boron nitride. The majority of surface grinders used in the modern era are at least partially automated. The work material is held on the table of a magnetic chuck and sometimes an electro-magnetic chuck depending on the specific machine.

 

What a Surface Grinder Does To Material

A surface grinder produces a high level of heat which will create stress on the material. After being run through a surface grinder, a material will be more apt to breakage or fracture than before it was run through the machine. A material can also lose its magnetic properties if its temperature is raised too high.

Overview and Advantages of the Hydraulic Radial Drill

Posted on by

Can you imagine the hassles of not being able to drill a hole through a work piece that is too large to fit in your drilling machine’s table? The limitations of your drilling machine may be inconvenient, but the radial arm drill press puts an end to this dilemma.

 

A hydraulic radial drill or radial arm press is a geared drill head that is mounted on an arm assembly that can be moved around to the extent of its arm reach. The most important components are the arm, column, and the drill head. The drill head of the radial drilling machine can be moved, adjusted in height, and rotated. Aside from its compact design, the radial drill press is capable of positioning its drill head to the work piece through this radial arm mechanism.

 

This is probably one of the reasons why more machinists prefer using this type of drilling machine. In fact, the radial drilling machine is considered the most versatile type of drill press. The tasks that a radial drilling machine can do include boring holes, countersinking, and grinding off small particles in masonry works.

 

Although some drill presses are floor mounted, the most common set-up of hydraulic radial drills are those that are mounted on work benches or tables. With this kind of set-up, it is easier to mount the drill and the work pieces. There is no need to reposition work pieces because the arm can extend as far as its length could allow. Moreover, it is easier to maneuver large work pieces with the radial arm drilling machine. Large work pieces can be mounted on the table by cranes as the arm can be swiveled out of the way.

 

Here are some of the major parts of the radial arm drilling machine:

 

Column – the part of the radial arm drill press which holds the radial arm which can be moved around according to its length.

 

Arm Raise – adjusts the vertical height of the radial arm along the column.

 

On/Off Button – the switch that activates and deactivates the drill press.

 

Arm Clamp – secures the column and the arm in place.

 

Table – is the area where the work pieces are fed and worked on.

 

Base – the radial arm drill press part that supports the column and the table.

 

Spindle – the rotated part of the drill press which holds the drill chuck used in holding the cutting tool.

 

Drill Head – the part of the drill press that penetrates through the material or work piece and drill through the specific hole size.

 

Radial Arm – holds and supports the drill head assembly and can be moved around on the extent of its length.

 

There are a number of advantages of using the radial arm drill press. One of these advantages is the amount of area that it can cover which is only dependent on the length of the arm. Another advantage is the considerable size of work that it can handle since the arm can actually swivel out of the working area allowing cranes and derricks to place work pieces on the table. Finally, less effort is required during the drilling process because the arm assembly seemingly is doing all that is needed for specific tasks to be completed.

Thread Milling VS. Tapping

Posted on by

There are some distinct differences between thread milling and tapping. This article explains the advantages and disadvantages of each so that you can make an educated decision about the strategy that will work best for your parts.

 

Tapping: Advantages and Disadvantages

The greatest advantage of tapping is speed. High-speed tapping centers set up with a rigid tap can thread holes in a fraction of the time it would take to thread mill the same holes. Additionally, tapping can thread deeper holes in harder materials such as steel.

 

A significant disadvantage of tapping is that a different size tap is required for each size hole that needs to be threaded. This can consume a large number of valuable, but limited positions in the tool magazine. Plus, having to switch tapping tools for all of the various size holes increases the cycle time.

 

Another disadvantage is that tapping does not allow for adjusting thread fit. Once the hole is tapped, the size and position of the thread is final. Also, rigid taps are used exclusively for interior threading of holes and cannot be used to mill threads onto the outside of a post or screw.

 

Finally, since the initial portion of a rigid tap is designed to plunge into material rather than making perfect threads, these tools are best for tapping through holes rather than blind tapping, which is threading holes that end within the material. In the case of blind tapping, the deepest threads in the hole are made with the part of the tool that is designed to plunge rather than thread. To complete these last areas as perfect threads, a secondary finishing tool is required and results in longer cycle times.

 

As general rule of thumb, it is best to employ tapping when you need to make a lot of holes with few variations in size.

 

Thread Milling: Advantages and Disadvantages

The primary advantage of thread milling is the ability to control the fit. A threaded hole is milled at a high RPM and the tool helixes into a previously-milled hole. So, the machine operator has the ability to adjust thread size using a strategy similar to using an end mill, rather than a drill bit to make a hole. This can be advantageous if there are tight tolerances on the thread sizes or if allowances need to be made for finishing such as painting.

 

Also, a single tool can be used in thread milling to make a wide range of hole sizes. This reduces both the cost of tooling and the amount of time associated with tool changes. Plus, a thread mill can create interior and exterior threads, right-hand and left-hand threads, as well as very large threaded holes (e.g. pipe threads). In the case of the latter, this eliminates the need to invest in a large rigid tap to thread big holes.

 

Furthermore, the thread mill gives the user the ability to design custom threads without having to invest in custom taps which can be very expensive and require long lead times. In the machining of very shallow blind threads in thin materials, the thread mill allows for maximum threads in a very short distance.

 

The one disadvantage of thread milling is you need to be equipped with a high-speed spindle in order to do it properly.

 

The Bottom Line

If you need more flexibility, have a range of thread sizes and types and require the ability to adjust thread fits, thread milling is the best choice. If speed is your requirement, then rigid tapping is what you need.

What are CNC Tool and Cutter Grinder and Its Applications?

Posted on by

Today’s tool and cutter grinder is typically a CNC machine tool, usually 5 axes, which produces endmills, drills, step tools, etc. which are widely used in the metal cutting and woodworking industries.

 

Modern CNC tool and cutter grinders enhance productivity by typically offering features such as automatic tool loading as well as the ability to support multiple grinding wheels. High levels of automation, as well as automatic in-machine tool measurement and compensation, allow extended periods of unmanned production. With careful process configuration and appropriate tool support, tolerances less than 5 micrometers (0.0002″) can be consistently achieved even on the most complex parts.

 

Apart from manufacturing, in-machine tool measurement using touch-probe or laser technology allows cutting tools to be reconditioned. During normal use, cutting edges either wear and/or chip. The geometric features of cutting tools can be automatically measured within the CNC tool grinder and the tool ground to return cutting surfaces to optimal condition.

 

Significant software advancements have allowed CNC tool and cutter grinders to be utilized in a wide range of industries. Advanced CNC grinders feature sophisticated software that allows geometrically complex parts to be designed either parametrically or by using third party CAD/CAM software. 3D simulation of the entire grinding process and the finished part is possible as well as detection of any potential mechanical collisions and calculation of production time. Such features allow parts to be designed and verified, as well as the production process optimized, entirely within the software environment.

 

Tool and cutter grinders can be adapted to manufacturing precision machine components. The machine, when used for these purposes more likely would be called a CNC Grinding System.

 

CNC Grinding Systems are widely used to produce parts for aerospace, medical, automotive, and other industries. Extremely hard and exotic materials are generally no problem for today’s grinding systems and the multi-axis machines are capable of generating quite complex geometries.

Flat Bed Lathe vs. Slant Bed Lathe

Posted on by

The lathe is piece of equipment that is used for turning, drilling and shaping certain materials including metal, glass and wood. There are two types of lathe machines based on bed alignment: The flat bed and slant bed lathe. And what are the differences between the two…?

 

Flat Bed CNC Lathe

 

As its name suggests, it is a flat CNC lathe where you are required to place materials accurately to avoid mistakes in the cutting process. It can be used for light and heavy metal machining, delivering a precise finish for the working material.

 

Slant Bed CNC Lathe

 

Slant bed lathes are aligned sideways. They produce a Z-axis movement. However, they only function at a certain speed throughout the machining process.

 

The Differences between Flat Bed and Slant Bed Lathes

 

Flat Bed Lathe:

It can handle both light and heavy duty materials with exact precision. Flat bed lathe has a high range of machining, stability and productivity. Only skilled professionals are allowed to handle this type of lathe because it is a heavy-equipped machine. It may cause injury if not properly operated.

 

Slant Bed Lathe:

It is advisable to use for light materials only. Slant bed lathe has a lower range of productivity due to its machining capacity. It is a user-friendly lathe where machining is a lot easier.

What Are the Different Types of CNC Machining Tools?

Posted on by

The most common types of CNC machining tools are the vertical milling machine, lathes, and drilling or boring machine. Other types include EDM machines, laser cutting machines, and water jet profilers. These are just a few of the examples used in the manufacturing industry today.

 

The acronym CNC stands for “computer numerical controlled.” In these tools, a computer or “controller” drives the machine according to G-code instructions. The machines are designed to quickly perform repetitive tasks accurately at high speeds. Common tasks include cutting, grinding and drilling.

 

Fabrication of modern CNC machining tools began as early as the late 1940s by John T. Parsons to produce wing sections for the United States Air Force. Today, the range of products made with these machines is vast. CNC machining tools produce highly specialized parts for machine and automotive industries around the globe. Other types of industries that utilize CNC machining tools are the woodworking and granite or stone industries.

 

The main component of CNC machining tools is the machine control unit. This unit reads and decodes instructions, generates axis commands and feeds motion commands to circuits that drive axis mechanisms. It also controls the spindle, coolant and tool change functions. Other components of CNC machining tools are a program input device, which installs a part program into the CNC control, and a part program, which controls the movement and functions of the machine.

 

Various types of machinery use CNC as a controller. A lathe or turning center is a common type of CNC machining tool. This type of machine is capable of performing various lathe-cutting operations automatically. Laser cutting CNC machining tools are another type, and use a focused beam of laser light to cut a wide range of materials.

 

CNC EDM machining tools operate by using a thin wire as an electrode. The resulting erosion caused by the arc is what does all the cutting. CNC controls the table movement, as the wire remains stationary during operation.

 

A machining center is the latest type of CNC machining tool. It is capable of performing various tasks such as milling, boring and drilling in a single setup. Pallets or worktables automatically exchange work pieces as needed. The machining center automatically changes tool heads to perform the specific tasks as needed.

Understanding CNC Collet Chucks

Posted on by

When considering the purchase of a CNC lathe or turning center, it is important to ensure that the workholding system is matched to both the machine’s capabilities and the type of work that it will be doing. For example, the workholding system for a large-bore oil-patch lathe that will be machining pipe threads is probably not going to be the right solution for a high-speed multitasking machine making hip joints.

 

Many CNC lathes and turning centers come equipped from the factory with a standard workholding system consisting of a three-jaw power chuck, a hydraulic actuating cylinder and a drawtube. The hydraulic cylinder is fixed to the rear end of the machine’s spindle, while the chuck is mounted to the front side, or working side, of the spindle. These two components are typically connected together via the hollow steel drawtube that passes through the spindle bore.

 

The opening and closing of the chuck jaws is accomplished through the axial motion of the hydraulic actuator’s piston. As the piston slides back and forth, the drawtube moves in unison, driving a wedge-shaped plunger within the chuck body. This plunger converts axial motion to radial motion, causing the jaws to open and close. The amount of gripping force that the jaws apply to a workpiece is directly related to the actuator output force and is easily regulated with a pressure valve.

 

As a universal workholding device, a three-jaw chuck functions well for many common turning applications. It can hold a range of part sizes is capable of operating at reasonable rotational speeds and achieves good accuracies—particularly when the jaws are bored in place.

 

However, there are many applications where a jaw chuck is not the best workholding option, which has led to the development of a range of alternative solutions. The most common among these is the CNC collet chuck.

 

A CNC collet chuck mounts to the working side of a CNC lathe spindle in the same manner as a three-jaw chuck and uses the machine’s existing hydraulic cylinder and drawtube for actuation. The installation of a collet chuck usually requires the fitment of an intermediate adapter between the chuck and drawtube to compensate for thread and position disparities. This adapter is custom machined for the specific lathe/chuck combination and is normally included in the price of the collet chuck.

 

Choosing the Right Collet Chuck

 

Choosing the right collet chuck begins by identifying the spindle nose of the machine on which the chuck will be mounted. All CNC lathe spindle noses follow international standards that clearly define the mounting interface dimensions. Common spindle nose configurations for the North American market include A2-6, A2-8, and 140 mm.

 

The next step is to determine the chuck’s required capacity, based upon the size of the parts that need to be held. For bar feeding applications, it is customary to match, or slightly exceed, the machine’s drawtube bore size.

 

Once the spindle mount and required capacity have been identified, the selection can be further narrowed based on specific features and benefits of the various models, including pullback versus dead-length operation; external clearance dimensions; RPM capability; and setup time requirements.

 

When properly matched to a machine, bar feeder and application, CNC collet chucks provide an economical and effective way of holding material less than 4 inches in diameter. Because collet chucks are generally matched with a bar feeder, some of which have magazine storage and are designed to maintain consistent gripping force at high speeds, they are the workholding choice for lights-out operations.

 

Di Chun Iron Work co., Ltd. is the experienced collet chuck manufacturer in the industry. We also provide a variety of quality power chucks, hydraulic cylinders, and chuck jaws.

Small Hole Drilling Applications

Posted on by

The applications of EDM small hole drilling might be expected to be very limited in scope. Indeed, it would be difficult to think of a more innocuous phrase than small hole drilling, a phrase befitting a niche technology. But this belies the reality of EDM small hole drilling as a machining method used in many industries, industries that value precision and the characteristic of EDM to drill through very tough materials. Its use in gas turbines is the best illustration of what EDM small hole drilling can do in your industry.

 

Gas Turbines and Hole Popping

 

A gas turbine is a highly adaptable type of internal combustion engine that converts the impulse generated by the combustion of compressed air and fuel into useful work. How this work is harnessed determines whether a gas turbine is part of a power generator or a jet engine. A jet engine harnesses the jet of exhaust gases created by combustion for thrust, for example. Common to all gas turbine engines, however, is a turbine located downstream of the combustion chamber, which gives them one of their most important characteristics—they are self-sustaining. The compressor that allows for efficient combustion is powered by the electricity generated by the turbine. But for such a critical role, gas turbines are subjected to an extremely hostile environment of intense heat and centrifugal forces, and it is no surprise that the alleviation of this problem has been a major impetus in gas turbine development.

 

The primary limiting factor in gas turbine development has been heat, and research looking to alleviate the problem of heat has focused on two areas. One area is material science. Since the problem of heat was recognized, many cutting edge alloys have been developed that can resist both the heat and centrifugal forces found inside a gas turbine. But today, this is not enough. Temperatures in modern gas turbine engines can exceed the melting point of even these advanced alloys. This prompted the second wave of gas turbine development, which focused on cooling methods. One of the most prevalent cooling methods is called film cooling. In film cooling, air is directed through holes drilled on the surface of a turbine blade, creating a film on the surface of the blade that acts as a barrier to super-hot exhaust gases. Modern turbine blades combine advanced, adamantine alloys with cooling holes, to which only EDM small hole drilling is suited.

 

The characteristics that suit EDM small hole drillings to applications such as turbine blade cooling hole drilling are its ability to drill through very hard materials, an absence of machine tool pressure, and pinpoint accuracy. An EDM electrode never makes physical contact with its workpiece, which means that an electrode will work regardless of how hard the workpiece is. This lack of physical contact also eliminates machine tool pressure, which can prevent working on a delicate workpiece like a turbine blade, and create burrs and other deformities. This lack of machine tool pressure also contributes to the great accuracy of EDM small hole drilling. Below are just some of the applications of EDM small hole drilling. This list is not comprehensive, but only suggestive of hole popping’s great versatility.

 

Fuel Injection

 

Fuel injection has essentially supplanted carburetion in automotive engines. Due to the superior precision with which fuel can be delivered to a combustion engine, fuel injection engines boast superior fuel economy, less toxic emissions, and require less maintenance than engines using carburetion. A fuel injector uses very small nozzles to atomize gasoline or diesel fuel, ensuring a precise and predictable delivery of fuel. This is why EDM small hole drilling is the favored machining method. A lack of precision in the diameters of nozzle openings could hamper proper functioning of a fuel injector.
