What To Consider When Purchasing Bar Feeders

A bar feeder is the workshop equipment that undertakes the task of automatically feeding metal bars into CNC milling machines. Those types of tools are used to increase the productivity of a workshop and allow CNCs to work unattended and during the night or weekends. Bar feeders are considered to be a CNC extension, so they are directly connected and controlled by the latter. Operators, however, may also set a particular feeding rate that is fit for an application manually. The metal bars are held on the storage chamber and are taken out one by one to be passed into the CNC milling chamber. Bar feeders today are capable of detecting abnormal operation, stopping the feed automatically. What to think about before purchasing As with everything that can be found inside a workshop, bar feeders come in a lot of shapes, sizes, and different technical characteristics. Since this machine is something that is bought on the premise to work well in collaboration with another machine (CNC), buyers should be particularly cautious on what model they should choose. Here are some of the most important points for consideration: Size of Magazine The size of the magazine that holds the bars is a critical factor to consider when buying a bar feeder. Determine what type of bars you want to process (gauge class) and calculate how many of them can be held on the magazine. Then consider the feeding rate to figure out how many hours of unattended operation you can get from the feeder. Usually, a minimum of 8 hours (night shift) should be preferred. Lengths of Part and Spindle Each part that is produced on the CNC requires a specific amount of bar length to be realized. Machinists should calculate the total bar size, subtract the length of the part that is held on the CNC spindle and divide with part length to determine the number of the workpieces can be produced with each bar. This can indicate if a bar feeder choice is good or not, as sometimes a slightly longer bar could be enough for one whole extra product. Operational Safety As bar feeders are required to work well for long periods of time without the presence of personnel, it is very important to have safety features that monitor the operation and check for errors in the process. Some safety net mechanisms that are used by modern bar feeders include sensors, load meters, infrared beams and streaming webcams that send video technicians remotely. Floor Space Needs Floor area is sometimes a workshop's most limited resource, and bar feeders are known to challenge this. As the machines get fixed on the spindle side of the CNC and since they are relatively long in almost all cases, machinists should carefully calculate whether their workshops have enough space for the addition of a bar feeder. Not only should the bar feeder fit next to the CNC, but there should also be enough space for maintenance, access to all compartments, and space to clench/unclench bolts. If the bars are loaded onto the machine with the use of a small crane, there should also be enough space to accommodate its maneuvering as well.

How CNC Machines Can Benefit Your Operations

CNC (Computer Numerical Control) tools are essentially automated machines that are based on a main electronic processor for the positioning and spindling of their cutting or milling head. CNC machines may be lathes, milling centers, drillers, or multitasking turning centers that feature "live" tools. Some of the latest developments in the field also include plasma and water jet cutters. The commands given to the cutting head are of positioning nature, but they can also regulate the rotation speed, use of cutting oils, or workpiece movement on a rotating index table. For this reason, there are no manual controlled wheels or levers at all. The commands can be either stored in an electronic medium connected to the CNC computer, or automatically generate a sequence of commands based on a given 3D model exported from CAD software.

Key Benefits

Using CNC machines generates a series of benefits that are very important for the efficient running of any modern workshop business. The increasing demands in the metalworking sector call for fast production combined with precise workpiece geometry, something that can only be achieved through the use of CNC machines. Workshops don't require as many employees as before to run efficiently, as one supervisor can monitor the proper operation of multiple CNC machines. 2. CNC supervisors only need a minimum of technical training to cope with their responsibilities, while machinists of the past required extended periods of practice before they could become productive. 3. CNCs are able to produce many items of the exact same design, without dimensional and geometrical deviations. Human operators on the other hand can't achieve such high levels of consistency no matter their skills or experience. 4. While human operators need frequent breaks and can only work for a certain period of time, CNCs know no limits as to how long they can keep producing items without stopping. Apart from short periods of maintenance, CNCs can work day and night without any problem. Items that require extensive measuring and accurate dimensioning take a lot of manufacturing time for a machinist no matter how many of those were produced in the past. CNCs however can quickly produce the same item countless times and without any geometrical deviations among the produced pieces. A CNC with "live" tools can produce items that even skilled and experienced machinists find impossible to materialize. A multi-tasking CNC can produce an item that otherwise would require processing from various different machines. This can streamline the production of a demanding item and dramatically drop its production times.

Possible Drawbacks

Although CNCs offer such great benefits to workshops, they also bring some hindrances that are important enough and require serious consideration. 1. The increased cost of acquisition of those automated machines is the main suspensive factor. The expected median profit and ROI must be carefully considered before buying a CNC. This high cost though is gradually decreasing as open source software tools are made available. Secondly, there is the lack of engineering and calculative skills in a workshop. As the need for those is eliminated by the CNC machine's automated nature, workshops may slowly become incapacitated in regards to the technical abilities of the personnel. 3. There is a chance that a CNC is badly calibrated or the workpiece bed get somehow misaligned. This can lead to countless of defective items before someone notices.

Horizontal Boring Machines: Considerations Before Buying

Horizontal Boring Machines from Absolute Machine Tools, Inc. vary from machines that are built to withstand heavy-duty use in industrial environments to more compact and much more accurate horizontal boring mills that are generally preferred more for their greater levels of precision which makes them suitable for delicate work. All horizontal boring machines, though, share the same operating principle and standard design arrangement, which places the milling head parallel to the ground plane, while the working piece is moved along the X axis on aligned railing. Horizontal Boring Machines are mostly used for hole drilling on large workpieces taking advantage of the stability that stems from the horizontal cutting direction. The wide product range of the Horizontal Boring Machines ensures that every project, no matter its complexity, can be realized using an HBM, but this is also what makes the process of buying the right one confusing and often quite overwhelming. Here are some tips to consider when looking for the most suitable HBM. What Materials Will Be Used? The primary parameter for consideration will be the material specifications. There are horizontal boring machines suitable for wood, steel, iron and other composite materials. Their difference is basically the drilling head shape and material, as well as the frame and chock design that derives from the various characteristics of the chosen material. Different Types of Boring Mills The second most important thing to take into account is the actual type of the machine that can be either the table type, the planner type or the floor type. The most compact of all is the table HBM that can also deliver the most accurate cutting results. Because of the fact that this type sits on a table, buyers should look for a stabilizing mechanism that relieves backlashing tendencies. On the opposite side is the floor type that is a much larger, stronger and heavy piece of machinery that can process larger workpieces. Specifications of Workpieces HBMs are machines that require rotational and cutting precision to deliver usable products. This is why machinists need to first determine the production specifications before purchasing an HBM. Specifications of great importance are factors like the product dimensions and resolution. Make sure that the HBM offers enough working space and traversing freedom to accommodate the production of the workpieces in use, and also check the weight limits of the working table. Other Considerations That said, depending on the production specifications that need to be fulfilled, the buyer should look for extras that will streamline the milling process and will make an all-around machining possible. Some of these valuable extra features may include a rotary table that is used for almost unlimited milling along six axis. While small HBMs are generally more accurate than larger ones, you may find large models with relatively higher precision for the right price. If your needs require such a combination of characteristics, make sure to check the resolution rating of the HBMs you are considering. Another very useful extra is an electronic controller that fully takes on the milling process, streamlining and automating the production of same pieces. This feature will render your HBM's operation even more efficient as it will only require occasional monitoring from the workshop personnel.

Ideal Ways To Use Index Rotary Tables Tables

Rotary Index Tables are high precision positioning tools used in special cases of milling and metalworking. Their basic function is to offer the machinist the ability to work based on fixed intervals around a horizontal or vertical axis. By turning a lever connected to a worm-screw that is positioned under the rotary table, users can turn it clockwise or counter-clockwise in full turns. The worm-screw drives some axles that are fixed in intervals under the table, so the table is turned with great accuracy. The ratio between the worm-screw and the axles determines the maximum indexing resolution, and so the applications that each RIT is suitable for. Unique Milling Techniques Rotary index tables can be used for a number of specialized processing techniques and provide solutions in demanding occasions. The most noteworthy utilization of RITs is when combined with a chuck, tailstock and stepper electric motor to work as a light lathe alternative. This use though requires special care and the fast turning of the worm-screw by the motor can accelerate the wear of the table axles. Many also workshops use RITs for the milling of bolt head indented features of various shapes (octagonal, hexagonal etc). Operators calculate the intervals that are needed for the processing of these features and set the table accordingly. Cutting & Drilling Uses Rotary Index Tables are also regularly used for the cutting of straight lines at any angle, arcs and circular shapes. The arcs, being a demanding milling process, can be achieved by adding a compound table so that the center of the table's rotation can be displaced, thus resulting in a progressively off-centric machining. It is often the case that a machinist is called to drill a large diameter hole that the driller can't handle due to its insufficient power. This is another case where indexing tables can help by helping the operator drill multiple smaller holes around the set center of the larger hole. This boring process results in a hole that is equally accurate in terms of dimension and inner finishing as an one-drill hole. Helical machining is another point where rotary index tables can prove their usefulness. Calling for high precision and demanding processing, helixes are not easily materialized using conventional tooling. To create something that takes shape in the three dimensional space, you will need to move the workpiece or the cutting tool along at least three axis (x, y, z). RITs can help on this endeavor by providing the helix stepping through their rotation. This also calls for some pre-calculation and setting depending on the helix mathematical characteristics. Maybe the most common use of the rotary index tables though is the drilling of equidistant holes on a circular flange. Using the tool for this purpose is an easy and straight forward activity that is only requires the calculation of the intervals based on the number of holes and their center to center distance. By re-positioning the flange in off-centric holes, one can further drill each hole into a larger one.

What To Look For When Purchasing A CNC Rotary Table

A machine shop's CNC Rotary table is the three-axis device that allows for geometric features to be contoured on a mounted workpiece. Adding to this, there is an actuation mechanism comprised of a worm screw and worm wheel driven by the servomotor, which, when linked to the CNC board, provides for a fourth and fifth axis. This programmable system works well in endless applications that increase "run cycles" by allowing for more cuts in a single operation. When you are able to avoid unclamping or refixturing a workpiece, accuracy and completion times are significantly improved. High Tech for Higher Speed With the hundreds of types and styles of CNC milling equipment enhancements, it helps to consult with those who actually use them. It is possible to get a worm screw system made from carbide and ion nitrite that allows for higher speed rotation with less wear while producing higher accuracy. Featured in this V-grade carbide is the toughness that prevents backlash in reversal movements. There are also CNC seminars where professionals impart their knowledge and plenty of websites that will provide useful information. Efficiency Improves Table Longevity A hardened steel way for high loading and wear resistance supports the table as well as the workpiece. CNC Rotary table longevity is improved through position accuracy that is within plus or minus three arc seconds through the rotary encoder that is part of the servomotor. Vernier scales enable table positioning to the highest degree of accuracy. Improvements Over Time Have More to Offer While it is true earlier models of the CNC Rotary table and indexers did not possess the accuracy or flexibility of control, today's models are extremely accurate and quite rigid. The variety of control options available through the interface have made tremendous improvements over the discouraging results of the past. There are trade-offs, and it really serves to explore all the advantages in order to evaluate particular needs and requirements. It helps to realize that terminology is not standardized. Plan on asking questions to clarify such terms as "high precision," "rigid," "accurate" and "brake torque," just for a few examples. Industry standards do not exist for testing and specifications. Confidence in a supplier should be a premium, and it is possible to purchase with a performance guarantee. Advantages to Seek The CNC Rotary table that is controlled directly by the system's CNC will provide the full fourth axis. The shop floor operator will not be required to do any programming, which reduces the chances of crashing due to operator errors. The infinite positioning means ultimate flexibility to take on any jobs. The sophisticated models will allow for simultaneous rotary X, Y or Z manipulations to perform true helical milling functions for more elaborate workpieces. For work of such variety that requires these moves, look for a true four-axis system. This may mean greater expense, but it will be worth it. However, when simply retrofitting existing equipment with fewer jobs requiring such moves, consider the more economically priced M-code or RS-232 systems. It is worth exploring these options as they are highly affordable. It will all come down to the type and volume of exotic jobs that are being run.
