Machining

Puzzled by the appearance of a choppy, spiral-shaped set of chatter marks showing up on a workpiece, a shop sought a diagnosis from Jeffrey Badger, Ph.D., who writes the Ask the Grinding Doc column in Cutting Tool Engineering.

Looking to streamline its process and improve part quality, Automated Design Corp. moved into a facility that enabled it to set up a machine shop.

Advanced machine tool controls infused with artificial intelligence (AI) can learn about your machining processes. With this knowledge, a CNC can automatically take action that boosts machining speed and accuracy, as well as slash unplanned downtime for maintenance.

The new GARANT MasterSteel SlotMachine from the Hoffmann Group is a solid-carbide roughing endmill, which achieves high feed rates when slot milling from solid steel. The innovative knuckle form profile produces extremely compact swarf. Therefore, the Hoffmann Group was able to construct the milling cutter with five cutting edges.

To further serve customers in Michigan, Röhm Products of America Inc., Suwanee, Georgia, partnered with industrial manufacturers representative Motor City Industrial Marketing.

Privet Fund Management LLC, Atlanta, completed the acquisition of Hardinge Inc., a global provider of advanced metalcutting machine tool solutions and accessories.

Tsugami/Rem Sales LLC announced its newest machine offering; the Tsugami M08J, a 2-axis turning center with a manual tailstock, programmable quill and A2-6 spindle nose.

The You Ji VTL-1200ATC+C is a 49" table/63" swing vertical turning lathe with full C-axis and live milling for heavy-duty turning and milling of large workpieces from Absolute Machine Tools Inc. This heavy-duty, highly productive VTL weighs in at 72,600 lbs. and features a rigid vertical column and a Meehanite castings base, which is heavily ribbed for reduced thermal distortion and vibration damping.

Hexagon's Manufacturing Intelligence division announced a new release of its HxGN SMART Quality online quality data and measurement resource management software, the enterprise IT solution designed to help manufacturers utilize aggregated quality data to gain actionable intelligence and insight for process optimization.

AccuteX's new AL-600SA CNC Wire EDM is from Absolute Machine Tools. The AL-600SA moving-table model can be fully equipped with 6-axis capability, PCD cutting circuit, and AccuteX's exclusive linear shaft motors that provide a 10-year positioning guarantee. These motors were designed and built fully in-house specifically for AccuteX wire EDMs.

Quicktech i-42 ROBO (pictured) and i-60 ROBO 4-axis mill-turn centers feature integrated 6-axis Mitsubishi robots for fast, automated loading and unloading of medium-diameter (i42: 42mm/1.68", i60: 60mm/2.36") bar stock. In addition to carrying out highly productive turning, the machines can perform complex milling with standard live tools.

The LND-65D-S3 is an 11-axis mill-turn center that can often produce parts faster than conventional twin-spindle, multi-turret machines with up to five tools in the cut simultaneously. This machine has a bar capacity of 65mm (2.56"), maximum turning length of 475mm (18.7"), and employs independent 2-axis cross slides that can overlap each other and the turret.
