BACK-END MACHINING CAPABILITY
A 5" chuck size sub-spindle driven by a powerful 5.5 kW ( 7 HP, 5 min. ) built-in type FANUC motor ( Integrated Motor ) for back-end machining is available on the GLS-1500L series.
The Z2-axis movement of the sub-spindle is applied with high performance linear guide way design which provides high speed high precision and low abrasion advantages.

Automatic part transfer of work-piece from main spindle to sub-spindle saves manpower and cycle time, while reducing accuracy lost, which will occur if manually handling the part from machine to machine.
A. Large diameter parts.
A1. Main spindle machining of front-end.
A2. Part transfer to sub-spindle.
A3. Sub-spindle machining of back-end.
B. Parts from bar stock.
B1. Main spindle machining of front-end.
B2. Bar pull-out & part cut-off with main & sub spindles synchronization.
B3. Sub-spindle machining of back-end.
With Ø 32 mm ( 1.25" ) bar capacity, the sub-spindle configuration is also ideal for machining long work-pieces such as small diameter shafts. Both ends of the work-piece can be supported by the main and sub spindles, allowing the middle section(s) to be accurately machined.
C. Long shaft parts.
C1. Main spindle machining of front-section.
Pull-out & machining of mid-section(s) C2. with main & sub spindles supporting
work-piece.
C3. Sub-spindle machining of back-section.
