The GPEL-30.25 excels at high-production grinding applications, processing a diverse range of materials with speed and precision. Shigiya's advanced user interface and CNC technology bring the extremely close tolerances, short cycle times, and versatile machining capabilities needed in today’s manufacturing environment.
The GPEL-30.25 combines a swing over table of 300 mm and a maximum workpiece length of 250 mm. The Shigiya design incorporates a built-in wheel spindle motor to reduce wheelhead weight. Shigiya also adopted a linear motor for wheelhead feed and high-output built-in servo motor for work spindle rotation, resulting in fast, stable grinding.
Accurate to 1 micron, the GPEL-30.25 features simultaneous two-axis control of the wheelhead feed (X-axis) and the work spindle rotation (C-axis). Workpieces are centrally clamped and machined with stable X-axis and C-axis control. The linear motor in the X-axis controls the eccentric. Furthermore, the table traverse type delivers high-precision grinding.
Shigiya emphasizes automated systems in the GPEL-30.25 for reliability and ease of operation. Machine operators can program all the pin diameters in one setup.
Related Glossary Terms
- computer numerical control ( CNC)
computer numerical control ( CNC)
Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.
- feed
feed
Rate of change of position of the tool as a whole, relative to the workpiece while cutting.
- grinding
grinding
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
- linear motor
linear motor
Functionally the same as a rotary motor in a machine tool, a linear motor can be thought of as a standard permanent-magnet, rotary-style motor slit axially to the center and then peeled back and laid flat. The major advantage of using a linear motor to drive the axis motion is that it eliminates the inefficiency and mechanical variance caused by the ballscrew assembly system used in most CNC machines.
- micron
micron
Measure of length that is equal to one-millionth of a meter.
