Tungaloy has announced a significant expansion of TungCut inserts with 87 total additional inserts in the latest PVD grades AH6235 and AH8005.

TungCut is an extremely flexible grooving tool system offering a large variety of chipbreakers and toolholders that range from standard mono blocks to modular blades with through coolant capabilities. Unique and strong insert clamping system provides the tool with process security and long tool life.

AH6235 is the latest titanium-enriched nano-multilayered PVD coating with extremely hard microstructure. Combined with a dedicated tough carbide substrate, the grade provides the insert with exceptional reliability during parting and grooving operations with interruptions. AH8005 is another PVD grade incorporating high aluminum-content multilayered Carbide Threading Inserts coating with high hardness. The grade integrates a dedicated carbide substrate with well balanced hardness and fracture toughness, demonstrating superior wear resistance during high speed machining.

Together with successful AH7025 grade for first choice, AH6235 and AH8005 grades will enhance TungCut performances in parting and grooving operations with interruptions, as well as grooving and turning Carbide Turning Inserts operations with aggressive conditions.

To help manufacturers enjoy benefits such as reduced cycle times and greater tool life when performing hard part turning, Sandvik Coromant has strengthened its existing offer in the ISO H05 to H15 application area with the introduction of two new grades: CB7105 and CB7115. The grades will be of Deep Hole Drilling Inserts particular benefit to those machining transmission components for the automotive industry, where lower cost per part can be achieved.

?Hard part turning has been proven to reduce machining time and costs by 70 percent or more in comparison with conventional grinding techniques, while also offering improved flexibility, better lead times and higher quality. However, these gains can only be realized using optimized insert grades. With CB7105, Sandvik Coromant has created a grade for hard part turning that offers enhanced crater wear resistance in comparison with existing solutions, while CB7115 is designed to provide users with better fracture resistance than other grades, according to the company. These benefits equate to higher speed and improved edge line toughness, respectively.

?Hard part turning is usually a finishing or semifinishing process where typical machining challenges include high surface and dimensional tolerance demands, along with competitive tool life. CB7105 and CB7115 have been developed to tackle these challenges through the application of a high-performing PCBN grade material and coating, as well as appropriately adjusted edge preparation on the inserts. In combination with high quality control during insert manufacturing, this results in a number of end user benefits.

?“CB7105 allows machine shops to achieve lower cost per part when used as part of a high speed machining strategy,” states Torbjörn Ågren, product manager, turning at Sandvik Coromant. “Alternatively, users of this grade can benefit from longer tool life at lower speeds. CB7115 is also designed to deliver lower cost per component, typically though the adoption of one-cut strategies at higher speeds.”

?A case in point saw one trial site increase production of case-hardened 16MnCrS5 (57-62 HRC) automotive components by at least 15 percent after switching to CB7105 and CB7115. CB7115 surpassed 600 components (at 0.15 minutes time-in-cut) with predictable surface generation and lower R_z value. The cutting speed High Feed Milling Insert was 170 m/min. (557 sfm), while feed rate was 0.22 mm/rev. (0.008 ipr) with a cutting depth of 0.15 mm (0.006 inch).

?Ultimately, reliable and predictable machining is always the aim when it comes to machining case-hardened or induction-hardened steel components, such as transmission shafts and gears. CB7105 and CB7115 offer updated PCBN material, edge preparations and improved edge-line quality to ensure better and more predictable tool life and edge-line security.

Coolant systems rarely get top billing as the bar peeling inserts key feature of a machine tool, but that is the case with the lathes and machining centers being introduced to this country by Hakusui USA Inc. (Schaumburg, Illinois). The line of machine tools includes four lathe models and two vertical machining centers. All of the machines have, as a standard feature, a high pressure mist coolant delivery system that creates a mist of ultra-fine water and oil particles. The company claims that this allows for significant increases in surface speed and metal removal rates and longer tool life.

This method of coolant delivery, which the company has dubbed the ECOREG System, mixes a water-based coolant with an oil lubricant in a high pressure air stream, creating extremely small particles. These particles are then injected through high-pressure nozzles designed to be precisely directed to the point of machining.

The coolant is a solution of an anti-corrosive agent and surfactants diluted in water. The ratio of water and solution varies from 20:1 to 30:1. The oil lubricant that the company recommends is a specially formulated vegetable oil but other oils can be used, with those formulated as extreme pressure lubricants being recommended. The advantage of the vegetable oil is that it creates virtually no environmental impact.

One of the main benefits of the system is that is uses very little liquid. The company says that, under typical machining conditions, its lathes consume about one liter of coolant in 55 hours of machining. The VMCs consume approximately the same amount under normal machining conditions. Despite this low usage, the system provides a substantial cooling and lubricating effect.

This effect is apparently due to the almost immediate evaporation of the mist on contact with the workpiece, cutting tool and chip. The misting of the liquid increases its surface area, enhancing its capacity to absorb heat. Pinpoint aim of the nozzle is critical however, because the high pressure delivery of the mist blows away chips, which carry off much of the heat generated in machining. High feed rates and spindle speeds, of course, help considerably to keep heat in the chips as they are formed. Because almost all of the mist evaporates so quickly, the chips are dry, aiding their disposal and increasing their value as a recyclable material.

The fine particles in the mist also allow it to penetrate the cutting tool/workpiece interface when injected at high pressure. Apparently, the ECOREG System creates particles that are small enough to enter the gap between tool and workpiece while high pressure overcomes the centrifugal force of the rotating tool or workpiece. Thus, a very small amount of the oil lubricant—0.3 to 0.5 cubic centimeters per minute—can be very effective, the company says.

In addition to the environmental benefits of this system, the company also cites improved machining results. The combination of increased speeds and feeds with the effects of high cooling and excellent lubrication results in better dimensional accuracy of the workpiece, finer surface finish, higher productivity and increased tool life. The company has not published direct comparisons for various applications but is inviting users to submit sample workpieces for testing at the company's technical center in Schaumburg. The company will then report on process improvements to be expected using its machine tools at the recommended settings. An increase in tool life as high as 400 percent is cited in the company's literature as a typical benefit.

Otherwise, the lathes and VMCs to which Hakusui is attaching its ECOREG System are of conventional design. The lathe line includes two 6-inch models, an 8-inch and a 10-inch model. The HL-06 lathe, for example, features 1,181 ipm rapid traverse in X and Z axes, with an optional 6,000 rpm spindle. For this model, the company has published a case history involving a 2.25-inch bar of 303 stainless steel machined with a carbide insert at a depth of cut of 0.04 inch and feed rate of 0.004 inch. With a spindle speed of 2,800 rpm and surface speed 1,680 fpm, resulting surface gun drilling inserts roughness is given as 0.00006 inch and circularity is given as 0.000031 inch TIR. In another example, the HTL-80, an 8-inch lathe, performed a rough cut on 1046 steel with an 0.08 inch DOC at 1,640 sfm producing a 3.4 micron surface finish. This operation consumed a half ounce of coolant per hour.

The two VMCs in the line are both designated as 40-inch models. The HV-40 is slightly smaller, with 30 by 17.7 by 19.7 inch axis travel and 7.5 hp compared to the HTV-40 with 40 by 20 by 20 inch travel and 10 hp. Both models have optional spindles, with an HTV-1000 model offering 10,000 rpm. All of the Hakusui lathes and VMCs are equipped with Fanuc controls.

The ECOREG System is also available as a stand-alone unit, model MRC21, which can be retrofit to existing machine tools.
