With three 14-position tool turrets and identical main and counterspindles, the new space-saving Index C100s are designed for fast, cost-competitive production of medium complexity parts turned parts from bar stock from 30 to 42 mm diameter. The C100 will be at IMTS Booth S-8136.

Ideal for small to medium lot sizes, the three-turret machines deliver high performance within a small floor space, and are targeted to handle fixed headstock work often run on Swiss-type machines.

The Index C100 offers users a highly productive means of machining stock in the 30 to 42 mm range with more tools (42 quick-change tools, fixed and driven), higher horsepower, and greater torque but with the rpm typical of Swiss-style machines.

The C100 with 30-mm bar capacity comes with 9,000-rpm spindles and 42-mm bar capacity is available with 7,000-rpm spindles. Both versions can run parts ranging to 200 mm in length. The C100 drives are powerful: 20/29 kW and 25/29 kW (100/40 percent) for the 30- and 42-mm versions, respectively. Motorized main and counterspindles are identical and liquid-cooled.

The machining flexibility of the C100 is a keynote of Index technology. Up to three tools can be at work simultaneously with both Y axes and backworking at the same time. And the counterspindle with linear-motor driven Z axis can be synchronized with travel of turret 3. Counterspindle pick-up from the spindle is accomplished in just 1.5 seconds.

Because the C100 is configured to complete a wide range of parts from simple to complex, small to large batch sizes, users can expect extremely high machine utilization rates, which allow the C100 to be very cost-effective. Parts can be unloaded from the main or counterspindle.

Simultaneous machining with two Y axes at the main spindle or a Y axis at the main spindle and also one at the counterspindle—each with 70 mm of travel—gives users the option to Cermet Inserts divide machining operations for optimum machining efficiency and flexibility This freedom also is a key to reduced cycle times. For example, users can machine simultaneously with up to three tools driven tools for complete machining in a single set-up, including heavy milling, and backworking with up to five tools.

The turret slides move in the X and Z directions on innovative single-plane guide ways. This permits rapids up to 60 m/min. and accelerations up to 1 G with maximum rigidity. The plate-type guideway of the turret slides also means turrets glide directly on the machine bed, assuring high stiffness and dampening, resulting in longer tool life—up to 30 percent longer tool life and better surface finish.

The open work area and vertical-bed machine design permits clear chip fall.  

Each MGMN Insert position on the 14-station turret is equipped for preset driven tools. Large tooling capacity means short setup times and very fast cycle times even for small batches. Tools are more easily accessible than on a Swiss machine and can be changed quickly. They lock with only one screw.

The CNC is easy to work with; plain text is used in display and operation and the screen shows all spindles and axes at one view. Superior programming with more than 70 user routines offers practical support down to the finest detail. Index programming contributes to optimum machine utilization and maximum productivity.

Assuring operator safety was a design consideration for the C100. Absolute measuring systems know axis and tool positions in every situation.

The upside to using robots for drilling holes is that they have the maneuverability to reach multiple sides of a workpiece. The downside is that they sometimes lack the rigidity required to handle the high axial forces encountered during conventional drilling operations, especially in hard metals. However, Orbital Drilling end-effector technology from Novator (Spånga, Sweden) may make robotic drilling more commonplace in machine shops and manufacturing facilities by overcoming the issue of limited robot rigidity.

Orbital Drilling is similar to helical interpolation routines that enable machine tools to create holes of varying sizes using a single cutter. As a tool spins on its own axis, an eccentric spindle head rotates it to the offset required to produce the desired hole diameter. The spindle head contains a proprietary mechanism consisting of an inner and Carbide Inserts an outer eccentric body. These bodies are configured so that their mutual rotation enables continuous radial offset adjustment of the tool. The drilling cycle (feed rate, orbital speed and spindle speed) is fully programmable. This makes it possible to produce not only cylindrical, conical and countersunk holes of various sizes, but also holes with more complex shapes. Plus, Orbital Drilling produces lower thrust forces than conventional drilling to enable robots to effectively drill burr-free holes in materials ranging from carbon fiber reinforced plastic (CFRP) to titanium.

During Orbital Drilling, the tool has only partial and intermittent contact with the workpiece. That, together with efficient air cooling of the cutting tool and the hole surface, enables drilling to be performed dry or with minimum quantity lubrication (MQL). Efficient heat extraction also reduces the risk TNGG Insert of matrix melting in composites and heat-affected zones in metals. Chips are small enough for efficient removal via an airflow extraction system.

Orbital Drilling is particularly effective for hole-making operations in stacked materials, such as CFRP/aluminum and CFRP/titanium used in aerospace applications. Both the wear factor and compensation curves are different for the stacked materials. To account for tool wear and differing material characteristics, the unit’s accompanying Orbital Manager software uses a compensation algorithm that enables it to dynamically adjust tool offset and other parameters during the drilling operation. According to the company, this makes it possible to drill a large number of holes to tight tolerances while significantly increasing tool life.

Novator’s E-D100 end-effector weighs approximately 130 kg and can create a maximum hole diameter of 25 mm. It offers a drill stroke length of 100 mm and uses a 9-kW, 30,000-rpm spindle.

The company also offers its PM Series of portable units for non-robotic applications. Available in 40- and 60-mm stroke lengths, these units are semi-automatic models with manually adjusted offset/eccentricity.

Water cutting, also known as water jet knife, referred to a kind of high-pressure water jet cutting technology, it’s high-pressure water cutting machine. Under the control of the computer, the workpiece can be carved arbitrarily, and it is less affected by the processed material quality. Due to its easy operation and good yield, water cutting is gradually becoming the mainstream cutting method in industrial cutting technology.

Historical Development

Early water cutting because the pressure of water is very small, and no abrasive is added, it can only be used to cut paper and other soft, low strength materials，which means its application range is very narrow.

Later, with the development of technology, high-pressure water pump can be used to cut more materials. Early water cutting relied entirely on the pressure of water to cut materials, but only cutting materials with lower strength than water pressure, the application is still limited.

Dr. Norman Franz has always been recognized as the father of the water knife. He was the first person to study ultra-high pressure (UHP) water knife cutting tools. Ultra-high pressure is defined as over 30 000 psi. Dr. Franz, a forestry engineer, wanted to find a new way to cut big trunks into the wood. In 1950, Franz first placed heavy objects on the water column, forcing water through a tiny nozzle. He acquired a short high-pressure jet (several times exceeding the current pressure) and was able to cut wood and other materials. His later research involved more continuous flow, but he found it very difficult to obtain continuous high pressures. At the same time, the life of parts is calculated in minutes, not weeks or months today.

In 1979, Dr. Mohamed Hashish began to study ways to increase the cutting energy of water knives in Frow’s research laboratory to cut metals and other hard materials. Dr. Hashish is recognized as the father of sand water knife. He invented the method of adding sand to an ordinary water knife. He uses garnet (a material commonly used on sandpaper) like sand. With this method, water knives (containing sand) can cut almost any material. In 1980, and water cutters were first used to cut metals, glass, and concrete.

Working principle of water jet cutting

The water-cut water jet starts from a pressurized pump and passes through a high-pressure tube to produce a pressure of 60,000 PSI, which is then ejected from the cutting nozzle. During the design process, small leaks can permanently damage the components and cause damage. Therefore, manufacturers and engineers will carefully handle the processing of high-pressure materials, using special technology to combine such machines. Users only need to know basic operational knowledge.

The cutting machine was applied in the industry in 1982, and it was first introduced in 1970. It is mainly used in the automotive, aerospace and glass industries in the industry, and the precision is continuously improved from these cuttings. The abrasive cutter can reach a pressure of 55,000 PSI, which is injected through a small nozzle at a speed of 762 m/s, which is 2.5 times the speed of sound.

Mixing the pomegranate sand into this high-speed water jet, mixing it in a mixing tube and then directly ejecting it from the sand tube to the material being processed at a speed of 305 m/s. This cutting process is actually a grinding and cutting process. The process, this power and movement are all produced by water.

The booster pump pressurizes the water again to achieve the desired pressure. It is worth noting that the abrasive cannot be added to the water or high-pressure water line because the line will wear through quickly. Therefore, it can only be added to the nozzle position to mix water and abrasive. At the same time, it can’t be too close to the exit, because it is necessary to give him a speed to accelerate, only the abrasive has a certain flow rate to have the cutting ability. In order to avoid the abrasive mixing of the abrasive and water, the water cutting nozzles are made of very hard, high strength materials such as tungsten carbide ceramic composites.

Advantages of water jet cutting

So what are the advantages of water cutting compared to traditional cutting methods?

Can be cut in a wide range. It can cut most materials such as metal, marble, glass and more.

Good cutting quality. Water cutting creates a smooth cut that does not create rough, burring edges.

No hot processing. Water cutting because it is cut with water and abrasives, does not generate heat (or produces very little heat) during processing, and this effect is ideal for materials that are affected by heat. Such as: titanium.

Environmentally friendly. Water cutting is cut with water and sand. This kind of sand does not produce toxic gas during processing, and can be directly discharged, which is more environmentally friendly.

Water cutting does not require replacement of the cutter unit, and a single nozzle can process different types of materials and shapes, saving cost and time.

Disadvantages of water jet cutting

The cost of water cutting equipment is second only to laser cutting, high energy consumption, high maintenance cost, and no cutting speed. Because all abrasives are disposable, they are discharged into nature once. The environmental pollution brought by it is also serious.

Cutting result of water jet cutting

Cutting thickness

The thickness of the water cut can be very thick, 0.8-100mm, or even thicker material.

Cutting speed

The water cutting speed is the slowest relative to wire cutting fast feed milling inserts and laser cutting, and is completely unsuitable for mass production.

Cutting accuracy

Water cutting does not produce thermal deformation with an accuracy of ±0.1mm. If a dynamic water cutting machine is used, the cutting accuracy can be improved, and the cutting accuracy can be up to ±0.02mm, eliminating the cutting slope.

Slit width

The water-cut slit is approximately 10% larger than the diameter of the knife tube, typically 0.8-1.2 mm. As the diameter of the sanding tube expands, the incision becomes larger.

Cutting surface quality

Water cutting does not change the texture of the material surrounding the cutting seam. Thermal cutting methods, such as laser cutting, change the texture around the cutting area.

Bar pullers don’t offer the extended amount of unattended turning time that bar feeders allow a lathe to enjoy. That said, they do allow shops to either gain some extra machining time overnight or enable one operator to tend multiple machines during the day. Plus, they’re a small fraction of a bar feeder’s cost, they don’t take up any floor space and they don’t need to be wired to the lathe.

A bar puller installs in a lathe’s turret and is used to pull a short length of barstock out of the lathe’s spindle. After the bar puller’s gripper secures the end of the bar, the lathe’s turret retracts along the Z-axis to bring a portion of the bar into the workzone. Once turning and part cutoff are completed on that section of the bar, the turret indexes the bar puller into position to retract the bar once again. This process repeats until the bar is consumed.

The issue with dedicated bar pullers is that they require their own turret position along with all the cutting tools for the various turning operations. Some companies, such as Somma (Waterbury, Connecticut), offer a combination tool that has both a bar puller and cutoff blade. This way, only one turret position is required for the functions of bar pulling and part cutoff. The combination tool also eliminates the need to index between cutoff and pulling, decreasing cycle time.

After turning is completed on the end of the bar, the device’s blade-style tool cuts the completed workpiece from the bar while the bar puller’s jaws Carbide Milling Inserts simultaneously engage the end of the bar. The puller’s jaws fully grip the bar once part cutoff is completed. The turret then can retract to position the bar for the next turning operations.

The model that Somma offers is adjustable to grip diameters from 0.125 to 3.25 inches. It uses spring-steel fingers that expand over the bar to provide the gripping force. A single screw is used to adjust the jaws for a new job. Each full turn of the screw moves both jaws in or out by 0.1 inch.

When using a bar puller, each new bar should be sized to fit completely within the spindle. During setup, the bar should be positioned an appropriate amount from the chuck so the first part can be turned. The first bar-pulling operation occurs after the first workpiece is created. Programmers must determine the number of parts that can be Shoulder Milling Inserts produced for a given bar length, because the puller can’t signal the machine’s control that the bar has been consumed.
