MMS JANUARY 2018 140 JEDD COLE | EDITOR | Modern Equipment Review Doosan Machine Tools' Puma 2600 SY II is a 10" class, subspindle Y-axis horizontal turning center designed to craft high- precision parts from a range of tough-to- machine materials. The company explains that the system has a bed designed for rigidity and accu- racy. An active thermal compensation system decreases the effects of thermal deformation by 60 to 70 percent over the previous model. NTN sliding bearings have been applied to all box guideways on the carriage, improving fine movement by more than 40 percent and wear resistance by more than 30 percent. In addition, the feed box and X-axis bearing mount have been reinforced for high rigidity. The built-in spindle minimizes vibration and provides better acceleration and a smooth, fast ramp-up, the company says. It generates a maximum 22 kW (30 hp) and 599 Nm (442.1 foot- pounds) of torque. The structure of the spindle bearings provides improved spindle runout (6 μm), making it more suitable to high-precision machining and better surface finishes. The 12-station milling turret also has been redesigned for improved durability and increased clamping force. BMT tooling provides high rigidity for heavy chip removal, fine surface finishes, long-boring-bar overhang ratios and extended tool life. The operation panel has a new ergonomic design and an updated Easy Operation Pack- age with improved setup, operation and maintenance programing. | Doosan Machine Tools America | 973-618-2500 | Tool-Loading Robot Uses Machine's CNC Software ANCA's custom industrial robot loader is designed to be a low-cost solution for tool loading. The robot does not have a separate, free-standing controller, instead using control software that runs concurrently with the grinding machine's CNC software. Operators perform the teaching using the machine's operator panel and a handheld pendant. | ANCA Inc. | 248-926-4466 | Lathe Offers Rigidity for Tough-to-Machine Materials
