PCBN Inserts Improve Feed Rates, Chip Flow

DThe M5F90 face-milling cutter ifrom Sandvik Coromant is designed for machining thin-walled aluminum automotive parts without burring, scratching or chipping. The two-in-one cutter can perform roughing and finishing in a single operation for faster and more efficient machining strategies.

The M5F90 cutter body’s diameter (25 to 80 mm/0.98" to 3.15") carries brazed PCD inserts that require no adjustment thanks to new production processes and therefore enable higher feed rates without vibration. Scratches, burrs and breakages on the machined part are said to be eliminated with a combination of optimal cutting angles, insert shape, edge preparation and cutting parameters. DCMT Insert

In terms of roughing, the tool works as a conventional cutter, with all rough-cutting edges positioned on the same diameter and height. The M5F90 can machine to a depth of cut measuring 4 mm (0.157"). With regards to finishing, this portion of the tool consists of radial and axial stepped cutting edges. Such a configuration promotes burr-free milling and good surface finish on thin-walled aluminum parts while enabling a close pitch-in order to avoid cutting vibration, according to the company.

“The inherent flexibility of being able to rough- and finish-mill makes it possible to machine different positions on the same part with just one cutter,” says Emmanuel David, global automotive product manager. 

Although designed for thin-wall milling operations on aluminum parts, such as gearbox cases and housings, the M5F90 is also able to handle other aluminum automotive part features, the company says.

The M5F90 is described as completing Sandvik Coromant’s milling cutter offering Cermet Inserts for aluminum automotive parts, complementing the M5B90, M5C90, CoroMill Century/590, M5Q90 and M5R90 tooling solutions.

Ceratizit Product Update Enhances Cutting Tool Solutions

Kennametal says its KSEM Plus modular drills combine the high feed rates and length/diameter capabilities of modular drills with the high speed and low consumable costs of indexable drills. The drills offer increased metal removal rates and productivity in various applications, including the energy market. The drill bodies accept a range of head diameters, and inserts or heads can be replaced without removing the body from the spindle.

The tools consist of a steel body coupled to a high-strength steel head. The drill body features a central coolant hole that TNMG Insert maintains rigidity while allowing maximum coolant flow through the tool. A margin and relieved clearance eliminate trapping of chips between the drill body and hole wall to increase tool life and improve surface finish, while differential helix flutes smooth chip evacuation and maintain rigidity. A single tool body can accommodate a range of drill head sizes. The tools are suited for steel, stainless steel, cast iron and nonferrous alloy workpieces.

The drill head features four coolant holes for increased tool life and chip flow. Produced from high-strength steel, the head uses a combination of KSEMP inserts in the center to provide high feed rates and centering capability and DFT D inserts on the periphery to balance cutting forces and reduce chip load per edge.

The modular drills are available in standard lengths of 5 × D, 8 × D and 10 × D in metric and inch sizes Shoulder Milling Inserts from 1.250" (31.75 mm) to 2.756" (70 mm).
