Samputensil Introduces High Capacity Grinding Machine
January 6, 2006—The new 250G generating grinding machine from Samputensili, introduced at EMO 2005 was developed to achieve a shorter cycle time.
According to the companys press release, the vertical grinding machine combines the strength and stability of hobbing machines with the precision and flexibility of grinding machines. This machine is suitable for virtually any production environment.
Features include a machine bed made of cast iron. The subassembly carrying the grinding spindle is constructed of light metal and runs on anti-friction guideways. Shifting is performed by a ballscrew spindle. Absolute precision of movement is ensured by the subassembly, which consists of the spindle with the electric drive, absolute position encoder and tailstock. The spindle offers an output of 48 kW, a maximum speed of 2,000 rpm, and can be equipped with temperature sensors and position measuring systems for real-time control of its function to permit adjustments as necessary. Synchronization between the tool and workpiece is ensured by the Siemens CNC control system as well as a magnetic encoder with resolution in the thousandths. In addition, the stream of coolant is constantly adjusted to the tool diameter and aligned to the point of contact between the tool and workpiece, which varies depending on the wear of the tool.
The machine is equipped with a modular gantry loader that allows the S250G to be directly incorporated in existing production lines. No other devices are required for handling of the workpieces. To reduce the ancillary and auxiliary process times of the machines to a minimum, centering (stock division) takes place outside the work area before the workpieces are positioned on the workpiece spindle and while grinding is taking place on the machine.
