JTEKT e-500H vs JTEKT Toyoda GL4i-50
JTEKT vs JTEKT · CNC Grinding Machines
Summary
The JTEKT e-500H and the JTEKT Toyoda GL4i-50 are both listed as JTEKT CNC grinding machines. JTEKT publishes few comparable figures for this pair: the table has a single row, rapid traverse, and that one figure says little about how either machine grinds, so no overall winner is named here.
The listed applications separate them. The JTEKT e-500H is aimed at medium to large cylindrical parts such as large crankshafts, turbine shafts and rolls. The JTEKT Toyoda GL4i-50 is aimed at high-volume OD grinding of shafts, pins and journals in a compact footprint.
Specifications Comparison
| Specification | JTEKT e-500H | JTEKT Toyoda GL4i-50 |
|---|---|---|
| Rapid Traverse | 60 m/min ▲ | 10,000 mm/min (394 IPM) |
Advantages
JTEKT e-500H
- Listed for medium to large cylindrical parts, including large crankshafts and camshafts
- Listed for combined OD and ID grinding on larger workpieces in a single setup
JTEKT Toyoda GL4i-50
- Listed for high-volume OD grinding of shafts, pins and journals
- Compact footprint for production grinding
- Switch variant listed for mixed straight and angular grinding
Verdict
With only one comparable figure published, choose by the work. The JTEKT e-500H fits shops whose parts are medium to large: big crankshafts, landing gear components, turbine shafts and rolls, including work that combines OD and ID grinding. The JTEKT Toyoda GL4i-50 fits high-volume OD grinding of shafts, pins and journals where floor space matters. Confirm swing, length and wheel data with JTEKT against the actual part before deciding.
