MMS AUGUST 2018 188 IMTS 2018 Grinding and Abrasive Machining Universal Grinding Machine Performs Straight, Angular Work Toyoda's GL4i-Switch universal grinding machine features an adjustable wheelhead for straight and angular applications and the capability to complete OD and angle- head work. These features enhance repeat- ability and reduce cycle times by enabling the machine to run multiple operations in a single setup, requiring fewer offsets or adjustments to the part. The machine's workhead swivels in increments of 0, 30 and 45 degrees for flexible grinding, includ- ing smaller-diameter journals. Designed for high-production manufac- turing, the machine features the company's stat bearing and floating plate technology for accuracy and positioning. A reinforced cast iron bed improves coolant flow and reduces thermal displacement. The machine uses the company's Toyopuc-Touch conversational control, which gives the operator intuitive data-entry capabilities with visualization of equipment status for smart manufacturing. For large-part grinding applications, the machine comes with a distance between centers ranging from 500 mm (19.7") to 2,000 mm (78.7"), a swing ranging to 400 mm (15.7") and increased part capacity ranging to 300 kg (661 lbs). | Toyoda Americas Corp. | South, Level 3, Booth 338519 Twin Spindle Grinder Performs Complex Inner Diameter, Outer Diameter Grinding Supertec Machinery's EGM-350CNC twin-spindle inID grinder supports two individually programmable spin- dles, combining an ID spindle with a secondary spindle capable of face, shoulder and OD grinding. The grinder can also bore with a boring bar prior to the ID grind. With a maximum grinding diameter of 15" and a maximum grinding depth of 10", this multi-spindle design is meant for grinding flanges, bearing races and other parts requiring the grinding of different locations on a single part. The grinder enables the operator to grind the ID, face and shoulder in a single setup. The ID spindle design features a cartridge-type, motor-driven spindle, which enables simple change-over from one spindle to another. The ID spindles can range from 10,000 to 50,000 rpm, while 100,000-rpm air spindles are also available. The secondary face-grinding spindle can handle grinding wheels ranging to 5" in diameter. NSK linear guideways and precision ballscrews on all three axes provide increased accuracy and rigidity. The grinder fea- tures either the FANUC Oi-TF with G-code/M-code pro- gramming or the Mitsubishi M80 conversational control. The Siemens motor with inverter drive enables variable speeds on both grinding wheel spindles. The workhead features an A2-6 spindle with an 8" three- jaw hydraulic chuck. An optional oil and mist collector and six-position automatic toolchanger (ATC) are also available. | Supertec Machinery Inc. | North, Level 3, Booth 236922
