After adding four-axis or five axis rotary table on the machine tool, multi axis machining can be realized, which can improve the machining efficiency and yield. With the improvement of manufacturing automation in China, the demand for rotary table increases significantly.

Now, I will introduce the situation of several rotary table brands in China. We will divide them into four categories: Europe andAmerica, Japan, Taiwan and Chinese brands.

Taiwan: TJR, Detron and GSA are the main brands, as well as DEX, Autocam and HW. These rotary tables are not only configured on Chinese brand machine tools, but also sold to end customers. Their precision is not high and their service life is not long, but they can meet the requirements when machining parts with low precision. Some users will consider these brands when their budget is limited. Among these brands, TJR has the best sales volume, with an annual sales volume of more than 10000 sets, because they have the most complete distribution network, complete models and cheap prices.Most importantl

China: there are many locally four-axis brands in China, such as Gutia,Silvercnc, Blue tech, CP and Deshu. The product quality of these brands is comparable to that of Taiwan. Due to more favorable prices and fast delivery, they have occupied the market of most Taiwan brands. The four axis of Chinese brands mainly adopt roller cam structure or harmonic structure. The wear resistance of roller cam is better than that of worm gear, with long service life and good accuracy retention. The price of harmonic reducer rotary table is low, which is suitable for 3C industry. These two structures meet the needs of the market and have been recognized by customers.

Stay with a proven process or go for greater performance and flexibility with newer technology? That was the decision facing Autocam Corp. (Kentwood, Michigan), a manufacturer of precision metal components, when one of its auto industry customers increased the size of an order for a part for a fuel injection system. The equipment that the shop was using to process the part was already running at capacity, which meant that to increase production for the part the shop either had to buy more of the same kinds of equipment—the part was being machined in multiple operations across several machines—or come up with a better way to make it.

Autocam was reluctant to simply expand the existing production process. "The fuel injection part is a good example of today"s more demanding parts," explains Rick Koenig, Autocam product manager. "It cannot be made complete in one setup on our multi-spindle cam automatics. We run it over several pieces of equipment to machine all of the required features. Secondary operations are expensive, however, therefore we prefer to avoid them where possible to keep costs down."

Then there was the matter of flexibility. In the world of auto part manufacturing, frequent changes in order quantities are a fact of life. When order quantities decline, firms serving that market need to be able to quickly change over their production equipment to other jobs. The additional secondary-operation machines that Autocam would have to buy represented a sizeable investment, yet they were not particularly easy to redeploy.

Autocam decided that it would continue to produce fuel injector parts by the existing process. However, the additional order would be processed on CNC multi-spindle screw machines capable of producing the fuel injection part complete in one setup. The firm reasoned that the investment in CNC multi-spindle screw machines would be offset in part by the savings achieved by not having to perform secondary operations on the parts—in particular a final, costly, OD-grinding operation that the existing process needed to remove the nicks and scratches that the parts acquired during processing.

In addition to enabling Autocam to produce the part complete in one setup, the CNC multi-spindle screw machines also better suited the firm"s flexibility needs. "The multi-spindle cam automatic is a very robust, repeatable machine, but it takes a long time to set up for the next job," Mr. Koenig explains. "You have to order the cams, wait for them to be made . . . it can take weeks to get to the point where you can make trial cuts. By contrast, the CNC multi-spindle screw machine can be changed over to run a new part in minutes to hours.

Accordingly, Autocam purchased several MultiDECO 20/8, CNC, eight-spindle screw machines from Tornos Technologies U.S. Corp. (Brookfield, Connecticut). Each machine forms the heart of a highly automated machining cell (shown above) capable of making the fuel injector part complete in one setup so that no secondary operations are required.

To solve the problem of the scratching of the bars, Autocam approached Pietro Cucchi America Inc. (Elk Grove Village, Illinois), manufacturer of bar feeders for multi-spindle screw machines. Autocam was already sold on a space-saving feature of the firm"s bar loader: Unlike older bar feeders for multi-spindle screw machines that feed the bars into the screw machine"s stock reel, the Pietro Cucchi bar loader feeds the bar directly to the machine"s spindles, eliminating the need for a stock reel. The result is a much more compact arrangement, saving all of the space normally occupied by the stock reel.

A standard feature of the Pietro Cucchi bar feeder addressed the problem of the longitudinal scratching of the bars. Many multi-spindle screw machines have feed fingers that pull the bar into the screw machine. The bar feeder takes over the function of incrementally feeding the bars to the multi-spindle screw machine, pushing them into the machine from the rear. This allowed Autocam to remove the feed fingers from the screw machine, eliminating the source of the longitudinal scratching of the bar.

The rear-feed feature provides still another major advantage: The back end of the bar is secured in a rotary spring collet on the bar pusher, and when the bar has been consumed, the bar pusher retracts to the back of the bar feeder where a gripper unit extracts the remnant from the bar pusher, drops it, and inserts a fresh bar. Removal of the remnant at the rear of the bar feeder eliminates the danger of damage to the screw machine tooling, the possibility of jamming the chip conveyor and damage to finished parts.

To solve the problem of the scratching of the bar stock where it enters the collets of the multi-spindle machines, Autocam and Pietro Cucchi worked together to develop a plastic bushing that mounts in the spindle. The bushing keeps the bar centered in the collet opening (prevents it from sagging to the bottom) and keeps it rotating at the same speed as the spindle. The circular scratches formerly caused by the slight misalignment of the bar relative to the collet and the difference in their rotating speeds have been largely eliminated.

According to Autocam"s Mr. Koenig, the bar loader is about 3 percent faster than bar loaders that attach to stock reels. Bar feed-out consistency is better too. "Prior to the Pietro Cucchi loader, the variation in the feed-out of the bar was as much as 500 to 600 microns," Mr. Koenig recalls. "That variation has been halved by the new loader, to 300 microns, which in turn has halved the amount of bar stock that must be faced off to ensure uniform part length."

As mentioned earlier, nicks and scratches, which could affect the performance of the fuel injector parts, are not acceptable. Accordingly, not only must scratch marks be avoided, for example, at the point where the rotating bar is fed from the bar feeder into the screw machine"s spindles, or when a part is transferred from a spindle to a counter-spindle, but the completely machined parts must also be prevented from coming into contact with each other as they exit the machine.

Autocam solved the latter problem with a completely automatic part-unloading system. As finished parts exit the machine, they are automatically gaged to catch defects caused by unpredictable problems, such as incomplete cuts caused by chip bird nests. Defective parts are automatically ejected. Good parts are placed one at a time on a tiny conveyor that carries them through a cleaning operation (photo on page 38).

"Actually, it"s a double solvent wash to ensure that we remove all of the cutting oil from the parts," explains Steve Schoonbeck, Autocam manufacturing engineer. "Most of the oil is removed in the upstream stage. The second stage gets any remaining traces. Once a week or so, we"ll remove the upstream solvent for cleaning, replace it with the downstream solvent, and start with fresh downstream solvent. Cycling the solvent through both stages helps us hold down total consumption."

Parts are conveyed through the washer to an exit station where a Faraman tabletop robot, made by Samsung Electronics, removes them one at a time and loads them in a pallet mounted on a two-pallet indexing table (photo sequence on page 38). The robot is programmed to insert a part in each pallet hole. When the pallet is full, the table indexes 180 degrees, which moves the full pallet to an opening in the robot enclosure where it can be safely removed without interrupting the operation, and presents a fresh pallet to the robot.

The robot is portable. When it is no longer required for the fuel injector part, it can be quickly and easily moved to another machine, if necessary, to provide automated unloading capability for another job. Mr. Schoonbeck is impressed with that flexibility. "We use a lot of X-Y tables at Autocam (tables that move in X and Y to position a hole for the next finished part), but they"re usually dedicated to specific jobs," he notes. "The robots are a real improvement since we can redeploy and quickly adapt them to other jobs when the need arises.

Autocam"s decision to produce the additional fuel injector parts on CNC multi-spindle screw machines, instead of by the existing process, turned out to be the right move. By producing the parts complete on the CNC multi-spindles, the firm has eliminated secondary machining operations on the part and avoids the wear and tear that goes with moving them through the shop—a paramount consideration.

Historically, CAM software was seen to have several shortcomings that necessitated an overly high level of involvement by skilled CNC machinists. Fallows created the first CAD software but this had severe shortcomings and was promptly taken back into the developing stage.G-code set for increased flexibility. In some cases, such as improperly set up CAM software or specific tools, the CNC machine required manual editing before the program will run properly. None of these issues were so insurmountable that a thoughtful engineer or skilled machine operator could not overcome for prototyping or small production runs; G-Code is a simple language. In high production or high precision shops, a different set of problems were encountered where an experienced CNC machinist must both hand-code programs and run CAM software.

In milling applications on hardware with rotary table and/or rotary head axes, a separate finishing process called contouring can be performed. Instead of stepping down in fine-grained increments to approximate a surface, the work piece or tool is rotated to make the cutting surfaces of the tool tangent to the ideal part features. This produces an excellent surface finish with high dimensional accuracy. This process is commonly used to machine complex organic shapes such as turbine and impeller blades, which due to their complex curves and overlapping geometry, are impossible to machine with only three axis machines.
