MMS DECEMBER 2018 104 JEDD COLE | EDITOR | Modern Equipment Review Turning SPOTLIGHT Millturn's Milling Spindle Suits Heavy Cutting Applications WFL Millturn Technology's M120 MillTurn machining center accommodates machining lengths ranging from 78" to 315" and offers a swing ranging to 48". Along with up to 168 hp and 8,680 foot-pounds of torque in the main spindle, high feed rates on all axes are said to enhance dynamics and productivity. The 74-hp, direct-drive milling spindle maximizes power even at low speeds, suiting it to large drills and milling cutters. The clamping forces of the B axis enable the use of damped boring bars with a diam- eter-to-length ratio of up to 1-to-14. A separate pickup magazine is available for heavy inner-diameter tools ranging to 5 ft. in length and weighing 320 lbs; another is available for tools ranging to 8 ft in length. | WFL Millturn Technologies GmbH & Co. KG 248-347-9390 | Insertable Form Drill Systems Reduce Setup Times Schwanog's PWP and PWP-D insertable form drill systems reduce setup times with an insert holder that stays in the machine during insert change-over. This design keeps the center height unchanged. The insertable carbide tool is ground individually per cus- tomer specifications. It can hold a minimum tolerance of ±0.02 mm and the repeatability is 0.02 mm. The systems are available in several carbide grades. The insertable form drill systems have a maximum bore diameter of 28 mm and a maximum depth of 16 mm. The company also offers solid carbide drills for larger bore sizes and deeper holes. The solid carbide drills are ground individually per customer specifi- cations and accommodate a minimum tolerance of ±0.02 mm. | Schwanog LLC | 847-289-1055 |
