The design freedom of additive manufacturing delivers increased performance to cutting tools. At the world’s leading exposition for machine tools, I saw various examples of this.
Ceratizit’s FreeTurn tooling is designed to be used with its High Dynamic Turning (HDT) method, which is said to enable roughing, finishing, contour turning, face turning and longitudinal turning with a single tool.
Walter USA’s Accure-tec A3000, with its vibration damping system, is designed to excel beyond 6 × Dc.
The TCL18-style chipbreaker for Tungaloy’s TetraMini-Cut line of grooving inserts is designed to minimize cutting force.
UNCC researchers introduce modulation into the tool path. Chip breaking was the goal, but higher metal removal rate is an intriguing secondary effect.
Walter USA’s G3051-P grooving system, designed for grooving along shoulders, uses MX22-2L/R indexable inserts inclined by 3 degrees in the insert pocket.
The MU5 double-sided indexable insert from Walter USA can be used for turning steel forged parts as well as stainless materials.
Tungaloy has expanded its TungCut series of grooving tools to include the CGP32-CHP parting blade.
Tungaloy has expanded its TungThread line of indexable threading tools to include 11ER external threading inserts as well as 8 × 8- and 10 × 10-mm square-shank holders
The TungBoreMini, a multifunctional drilling and turning tool from Tungaloy, is designed to combine the capabilities of drilling and OD and ID turning tools.
Dormer Pramet has added a new set of tooling to its parting-off and grooving assortment.
Rollfeed turning adds a third axis to turning operations that moves simultaneously with the X and Z axes to “roll” the cutting tool with a special insert geometry across the surface of the part. The result is reduced machining times, minimized tooling costs and high surface qualities.
Walter USA has added polycristalline diamond (PCD) grooving inserts to its Walter Cut GX grooving system.
Kennametal’s KBH10B and KBH20B grades, designed for hard turning, are available in double-sided inserts for materials as hard as 65 HRC.
Designed for the Supermini tool system, Horn’s HP geometry is suitable for drilling, boring, face turning and skimming.
Using a robust 10-sided insert from Tungaloy, this oil-industry remanufacturer was able to reduce the number of inserts used in interrupted turning operations.
EMO 2019: WhizCut’s WhizTwin cutting insert is said to reduce waste material by employing two cutting edges in the front for increased stability and strength.
EMO 2019: Ceratizit Group’s High Dynamic Turning (HDT) method combines its FreeTurn tooling systems with a turn-mill’s B axis or milling spindle.
Carmex Precision Tools introduces diamond turning inserts that are designed to enable users to machine hard materials faster than grinding or ceramics.
Tungaloy has added 22 shapes and geometries to its BXA20 line of coated T-CBN inserts designed for hard turning operations.
Walter USA’s WKV10 and WKV20 insert grades for the Perform line of turning tools are marketed as versatile and cost-effective for small- and medium-batch applications in cast iron (ISO K).
Seco Tool’s GL threading and grooving heads for Steadyline turning and boring bars enable deep-hole operations and reduce the risk of scrapping workpieces.
Tungaloy has added the PVD-coated AH8015 grade in several geometry types to its MiniForce-Turn series for machining heat-resistant superalloys, steel and stainless steel.
Kyocera Precision Tools has expanded its GBF grooving tool series for small-parts machining to include coolant-through holders and a chipbreaker for the making of larger groove widths.
