Overview of NC Rotary Indexing Tables

Posted on by

NC rotary indexing tables are used to index parts and components in defined, angular increments so that they can be machined, worked, or assembled in multiple operations. Tables consist of a circular steel plate, one or more spindles, a drive system, and pins that hold parts and components in place. Rotary indexing tables have either fixed or adjustable indexing angles. During each revolution, the table stops for a specified period of time so that an operation can be performed at each station. The bearings that support rotary indexing tables determine both the load capacity and accuracy. Angular contact bearings are more expensive than recirculating ball bearings, but provide better load capacity and axial stiffness. Cross-roller bearings are also commonly available.

 

NC rotary indexing tables are powered by pneumatic and electric motors, hydraulic drives, and manual actuation. Drive mechanisms can be located above, below, behind, or to the side of the table surface. Pneumatic rotary indexing tables are suitable for small and medium loads. They are powered by one of more pneumatic cylinders, each of which represents an index. During the return stroke, a pawl locks the table in place. With some devices, the pawl can be adjusted to change the number of indexes. Electrically-powered tables are generally faster than pneumatic devices and can handle heavier loads. Tables that are powered by hydraulic drives use a pressurized fluid that transfers rotational kinetic energy. Manually-actuated rotary indexing tables often include a hand crank or are loosened, turned, and adjusted by hand.

 

Selecting NC Rotary Indexing Tables

 

Selecting NC rotary indexing table requires an analysis of specifications and features. Specifications include maximum indexing increment, work table diameter, maximum axial load, and maximum radial load. A variety of features are available. Some table surfaces can be raised or lowered at a controlled angle. Others have more than one rotating work surface. Computer numerically controlled (CNC) devices provide greater accuracy and repeatability. Position encoders are often used to relay the position of the table surface. Both four axis tables and five axis tables provide variable X, Y, and Z axis motion. Four-axis table also provide part rotation along the X axis. Five-axis tables provide part rotation along both the X axis and the Y axis.

 

Applications

 

Applications for NC rotary indexing tables include assembly and equipment positioning, as well as various automation, inspection and machining applications. Most devices work well with machines that perform fast and simple vertical operations. Examples include industrial presses, screwdrivers, riveters, dispensers, pick-and-place units, and ultrasonic or resistance welders. Parts can be loaded and unloaded manually or automatically.

Overview of CNC Tool and Cutter Grinder

Posted on by

A tool and cutter grinder is used to sharpen milling cutters and tool bits along with a host of other cutting tools.

 

It is an extremely versatile machine used to perform a variety of grinding operations: surface, cylindrical, or complex shapes. The image shows a manually operated setup, however highly automated Computer Numerical Control (CNC) machines are becoming increasingly common due to the complexities involved in the process.

 

The operation of this machine (in particular, the manually operated variety) requires a high level of skill. The two main skills needed understand of the relationship between the grinding wheel and the metal being cut and knowledge of tool geometry. The illustrated set-up is only one of many combinations available. The huge variety in shapes and types of machining cutters requires flexibility in usage. A variety of dedicated fixtures are included that allow cylindrical grinding operations or complex angles to be ground. The vise shown can swivel in three planes.

 

The table moves longitudinally and laterally, the head can swivel as well as being adjustable in the horizontal plane, as visible in the first image. This flexibility in the head allows the critical clearance angles required by the various cutters to be achieved.

 

CNC Tool and Cutter Grinder

 

Today’s tool and cutter grinder is typically a CNC machine tool, usually 5 axes, which produces end mills, 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.

Tips for Buying Rotary Tables

Posted on by

Rotary table is used in the precision metalworking industry. It is made of a solid base that can be clamped on to the other fixture. In simple words, rotary tables are discs, which rotate freely or by using a worm (hand crank).

 

Rotary indexers are used in different applications like machining, assembly and automation. Other than this, these tables find usage in assembly and equipment positioning. When you are buying a rotary indexer, there are a few things to consider. These include:

 

Diameter of Rotation Dial

The worktable diameter is the surface area of the rotary indexer.

 

Measurement of Through-Hole Diameter

It is the diameter of the breadth of the hole present at the center of the workstation.

 

Maximum Radial Load

When the load is pushed against the rotating plate, the heaviest amount it can support on vertical or horizontal axis is the maximum radial load.

 

Maximum Axial Load of Rotary actuator

Maximum weight the actuators are able to bear at the time of concentric operations.

 

Actuator Speed

Maximum rotation speed set by the manufacturer.

 

Minimum Indexing Increment

Smallest angle setting on the table.

 

Rotary tables can be mounted in horizontal, inverted or vertical styles. When the table is mounted horizontally, it is in a flat, horizontal and upright position. In vertical mounting, surface of the table runs up and down. When it is inverted, the table is upside down in a horizontal angle.

 

The location of drive on rotary table depends on the mount. You can place the drives below, behind, on the top or on the side of the table. When the drive is mounted horizontally, it is located above the surface of the table. When the table is mounted horizontally, the side-mounted drive is placed to the side of the surface of the table.

 

The rotary table can be driven manually, pneumatically, hydraulically and electrically. If you are driving manually, the table should be loosened and it must be turned manually with the crank.

Milling Machine Types and Uses

Posted on by

Milling machines are used mainly for shaping and cutting solid materials such as metal, wood, plastics or even brass. These machines differ from a lathe in that the tool head itself rotates at high speed whereas with a lathe the part itself that is being worked on rotates. This sort of machinery varies greatly in terms of cost and in the specifications of the machine. Hobby machines will obviously be a lot more cost effective than their industrial counterparts.

 

So we will be a taking a look at some of the milling machine features and some of the important things to consider when looking to buy a machine for home or industrial use.

 

Types of Milling Machine

 

Found more often than any is the column type of machine. It has a few basic parts and is pretty simple. Materials can be drilled by means of the vertically suspended cutting device.

 

The turret mill is a more versatile option than the column machine. It is capable of producing many types of products as the spindle can be aligned in many different positions.

 

The C-frame is more usual to be found in an industrial workplace. It is tremendously powerful to cope with larger milling jobs.

 

Horizontal and Vertical Mills

 

These two types of machine are fairly similar, the main difference is the vertical machine’s spindle has a vertical orientation as the name suggests. It’s good for plunge drilling and cutting.

 

A horizontal mill has the cutter or cutters located on an arbor. This type of machine is good for heavy cutting like slots and groves for instance.

 

Digitally Controlled

 

The CNC (computer numerical control) machine or sometimes referred to as machining center is a highly accurate form of milling. The machine is set up usually via computer aided design technology. This sort of control allows the part to be engineered to a high level of complexity such as engraved elements and relief. The precision achieved is unsurpassed and with little operator input needed following the set up phase and the production of the test piece it’s also cost effective.

 

Important Considerations for Purchase

 

It will depend an enormous amount on what the machine is required to do of course. So it’s important to look at the complexity of the work to be done and consider the number of axis variants required. The power of the machine will also be important as will the speed that it operates at. As some milling machines will come with various attachments others will require these at additional cost. The overall cost may be important and some really good used milling machines can be found online if needed.

 

So I have taken a look at some of the milling machine types and their uses along with what sort of things to look out for when considering the right one to get.

About CNC Lathe

Posted on by

A CNC lathe is a machine that can spins material to do a variety of operations like sanding, drilling, cutting or sanding. Usually a lathe is used for more intricate cuts and Today, they replace the older multispindle lathes because they are easier to set up and operate.

 

A CNC lathe will use carbide tooling and is designed using a CAM process which creates a file that can be uploaded to the machine at a later time. The reason these are so popular is because you can set the machine once to do several pieces and it will continue to do them until you have programmed it to stop.

 

Each CNC lathe has a computer control that allows the machine to be controlled electronically, and this program can be modified to do a variety of things. When an operator runs a CNC lathe they have to have a lot of skill to understand the programs and how the programs to do the work.

 

You can work with wood when you use a CNC wood lathe or various metals depending on the project you are doing. The wood lathe can be used for wood but also for brass and Aluminum. There are also metalworking CNC lathes or milling machines that cut metal. You can do tapered work with these, drill holes, and create screw threads and more with these lathes.

 

Some CNC lathes are portable and others are stationary. In many shops for people who do woodwork for a hobby you would find a lathe because it is capable of making a lot of different designs and intricate cuts for things like stair railings, trellis’ or table legs.

 

The point of using a CNC lathe is to make a piece of material that is symmetrical and beautiful. This is done by placing the material in a machine and allowing that piece to be spun until it reaches the specification that was programmed into the computer. The cutting tools then move around it on the Z and X axis to cut away the material that isn’t needed to make the piece.

 

The process that the CNC lathe does is called turning and it can do a variety of shapes when it goes through the full process. Many machines are used to create a plain surface to make contour shapes, to taper the ends of some pieces and it makes threaded surfaces. You can also turn metal so that you can create rods bushes, pulleys or other shapes that are needed. In some industries they use a CNC lathe to fabricate parts that may have a cross section that is to move in a circular motion.

 

Any material can be used as long as it will hold up during the turning process while the software program is continuing its revolutions.

 

CNC lathes are best used when you want to turn out several pieces of the same size and shape and where you don’t want a lot of decoration. They do have their limitations but for the most part you can create nice pieces with this type of machine.

 

Cyclematic Machinery takes pride in manufacturing CNC lathe which features constant quality, technical competence, and competitive price. We have an efficient development team of well-experienced engineers who understand exact customer needs through complete market research and try to adopt the latest technology in designing & development of CNC lathes. Quality is the driving force behind Cyclemate’s success. For more information about CNC lathes, please feel free to contact Cyclematic!

Mill+Drill=Milling Drilling Machine

Posted on by

The milling drilling machine is an alternative to a milling machine. These combine a belt driven drill press with the dual coordinate abilities of the milling machine’s table for flexibility and efficiency.

The following discussion guides on advantages of drilling machines and milling machines:

 

Drilling machines are fixed style drills that can either be mounted on a stand or bolted to the floor or workbench. The speed can be changed on these machines by manually moving a belt across a pulley arrangement.

 

Drilling machines can offer its users many advantages. Firstly, the lever gives the operator a considerable mechanical advantage. As it is fixed to a table, this allows a vice or clamp to be used to position and secure the work piece making the operation much more precise. In addition to this, the angle of the spindle is fixed relative to the table, allowing holes to be drilled accurately and repetitively.

 

Most modern machines are technically automated with the use of computer numerical control (CNC) technology. Because of this they can be programmed to produce precise results, continuously. In particular, CNC drilling machines are useful for pattern hole drilling, small hole drilling and angled holes. Drilling machines are frequently used for random workshop tasks such as sanding, honing or polishing, and a variety of other rotating accessories in the chuck.

 

Milling machines differ to drilling machines in a variety of ways. These machines are used for reshaping metal and other solid materials. Milling machines come in two varieties, either horizontal or vertical. This refers to the position of the cutting tool spindle. Unlike drilling where the piece is stationary and the drill moves vertically onto the material, milling also involves movement of the work piece against the rotating cutter.

 

In a similar way to drilling machines, milling machines may be manually operated, mechanically automated, or digitally automated CNC. Milling machines can be used to carry out a number of tasks. Some of these are quite complex, for example, drilling, die sinking, rebating, routing, etc.

 

As with drilling machines, many modern milling machines are controlled by a computer. This provides them with more flexibility. When this is combined with the appropriate accessories; conical tools or a ball nose cutter, it can dramatically improve its precision with no impact on speed, providing a cost-efficient alternative to most flat-surface hand-engraving work.

 

Previously, these types of machines were very expensive to buy and operate but with the drop in the price of computer technology it has made them much more affordable and accessible. This has allowed more businesses to take advantage of this technology, improving competition in the industry.

 

Rong Fu is a manufacturer of milling drilling machines in Taiwan. The milling drilling machines are an alternative to a milling machine. These combine a belt driven drill press with the dual coordinate abilities of the milling machine’s table for flexibility and efficiency. A locking collet prevents the cutting tool from falling away from the spindle when lateral forces are experienced against the bit.

 

The Rong Fu Milling Drilling Machines combine the advantage of space-saving versatility with features you’ve come to expect. All milling drilling machines are manufactured to meet the highest level of customer requirements. Welcome to visit Rong Fu’s website to get more information about milling drilling machines!

CNC Milling Machines

Posted on by

CNC milling machines are also known as machining centers. These machines are computer controlled as with all CNC machines. They operate on the Z axis and are vertical mills that move vertically. They offer precision and speed where one aspect does not affect the other. These CNC milling machines offer a cost effective alternative to hand engraving, flat surface work.

 

The most advanced of the milling CNC machines are the 5 axis machines that offer a wide range of capabilities. Horizontal milling machines are available and this is usually the lines of the 5 axis CNC milling machines. Basically, with the 5 axis machines, virtually any project can be done. One could sculpt the human head with ease with one of these machines.

 

At one time the machines were quite expensive to purchase and to operate. Now, because of the declination in the cost of computers and the availability of free operating systems, the CNC milling machines have dropped to more affordable prices. This has allowed many more shops to take advantage of this type of technology and has caused more competition in the machining industry. The shops now usually specialize in the type of work that they do.

 

There is a variety of different tools that can be used with this type of machinery. In the US, the most common CNC miller tooling is the CAT tooling; however, now a better alternative called BT tooling as raised the bar. BT tooling can be easily confused with CAT, so be careful.

 

The CNC milling machine can be either purchased brand new or as a used product. There are companies who specialize in milling CNC machines that cater to specific industries. A used milling machine or machining center can be more cost effective and can come with some type of service and warranty package if purchased from the right dealer. With these types of machines, because of the larger expense that it can put onto a company, it is tempting to go with a cheaper, used version; however, that may not always be best. Make sure that if you do purchase a used machine that there is some kind of guarantee and that the machine was taken out while still in operation.

 

CNC milling machines can come in many different types. There are gun drilling machines, horizontal boring mills, five axis milling machines, and many more. There are several different manufacturers of these machines that include top brands such as: Heidenhain, Phoenix, TOS and VTEC just to name a few. If interested in purchasing a top of the line machine, make sure that the dealer offers service solutions to help with upkeep and maintenance of the machine in the early stages until someone from your company can learn how to do it. Well established dealers can offer rebuilding services of old CNC milling machines. This too can be a cost effective alternative to purchasing brand new.

 

To learn more about CNC milling machines, contact Jiuh-Yeh CNC Milling Machine Manufacturer. They will be able to offer answers to your questions on a wide range of issues that is related to CNC milling machines.
