IMTS PRODUC TS :: 57 Toolholder Features Increase Clamping and Versatility Vargus USA | West Building and Annex Level 3 | Booth 432251 Vargus' Groovex MicrOscope system for internal micromachining operations in bores as small as 1.0 mm (0.039") now includes three new toolholder designs for increased clamping and versatility. Select MicrOscope inserts are now available with coolant in different boring and grooving operations, also. Insert features include shrink toolholders with newly designed grip for vibration reduction and long tool life, according to the company. Shrink toololders are available for all MicrOscope inserts in 4-mm to 7-mm insert diameter. The round tools and double-sided round tools without the shoulder have a four-flat design; can be placed from both sides of the machine tools table and are available for all MicrOscope inserts in 4-mm (0.157") to 7-mm (0.276") insert diameter. Double-sided round tools are available in 4 mm and 5 mm (0.157" and 0.197") or 6 mm and 7 mm (0.236" and 0.276"). Inserts with coolant features include high-pressure coolant- through tools, better chip evacuation that is said to be vital for secure machining in internal operations and long tool life. Ap- plications with coolant include boring, boring with chipbreaker, boring with chip former, boring and profiling, square grooving and pre-part off. CAM Software Increases Tool Life, Machine Usage DP Technology Corp. - ESPRIT | East Building Level 3 | Booth 133210, 215220 DP Technology's Esprit CAM software enables manufacturers to streamline their workflows and reduce silo formation, according to the company. It contributes to increased tool life and machine usage and improves access to practical knowledge for process improvement. The software enables the creation of a digital twin of a machine tool for programming and simulation. The twin displays on-screen the processes that occur on the shop floor. Workpieces and cutting tools are set up virtually, resulting in precise simulations and im- proved productivity and tool paths. The software also connects workflow steps, from CAD design to finished part, with a digital thread to make sure that no manufacturing process becomes siloed. The thread reads part data from CAD software and creates G code and setup sheets. It then passes this data on to enterprise resource planning software. Machine-aware CAM programming is said to increase tool life and reduce cycle times. The software's ProfitMilling and ProfitTurn- ing applications consider the machine tool's axis positions and limits, acceleration capabilities and attainable cutting speeds to increase machine speed and improve surface finishes. The applications enable users to make better toolpath choices. Rotary Transfer Machine Expands Capacity of Previous Models :: Hydromat Inc. | South Building Level 3 | Booth 338348 Hydromat's Eclipse 12-100 12-station rotary transfer machine updates previous models with a heavy casting mounted on a frame of welded steel. The machine casting is 2 m in diameter, almost twice as large as the company's previous 12-station machine. The ductile iron casting is designed for the use of semi-perma- nent tool spindles, each with three-axis capability to eliminate the need to either change tool spindle sizes or add three-axis flanges for different cutting processes. The machine features all-electric servo spindles and slides. No hydraulics are needed for tool spindle motion, and the tool spindles are larger than previous spindles to accommodate heavier cuts and larger parts. The bar-fed collet version of the machine has workpiece di- ameters ranging to 65 mm (2.5") and features workpiece lengths ranging to 180 mm (7"), with 127 mm (5") of material outside the collet. An indexing-chuck version features a table with vertical chucks capable of 360-degree rotation of the workpiece. This system accommodates mid- to high-volume, precision production of irregularly-shaped castings or forgings, and its flexible design accommodates families of parts. The indexing chuck machine uses hydraulically actuated, self-centering, two- or three-jaw chucks or custom clamp fixtures.
