Newly engineer A new-from-the-ground-up high-precision built-in spindle capable of delivering high power rating of 7.5kW (10HP) as standard or llkW (15HP) as option is dedicated to both spindles of the 11-3. With its high-power performance and low inertial rotation, this spindle quickly accelerates from lower speed to higher speed rotations, thereby eliminating idle time. Additionally it develops high torque performance at lower speed range enough to perform heavy- luty cutting and large-diameter drilling and tapping with no problem. performance chart •Acceleration time from 0 to 4000mm1 2.2 sec. (in the case of llkW (15HP) spindle with 8" chuck.) 3.0 sec. (in the case of 7.5kW(10HP) spindle with 8" chuck.) •Cutting power: •Turning : 01.6mm2 (0.025sq.in.) for JIS S45C (medium carbon steel) at surface speed •Drilling : 022mm (7/8in.) for JIS S45C (medium carbon steel) at surface speed of •Tapping : M18 for JIS S45C (medium carbon steel) at surface speed of lOm/min (33fpm) High-stiffness feed units and bed with smallest thermal displacement The combination of the traveling spindle stocks of our own, the X-axis and Z-axis integral feed units having broad and wide-angle slideways as well as the monoblock bed with slideways assures high stiffness and allows high-efficiency machining together with ample capacity of each feed axis thrust. In addition, our own structural measure against thermal displacement provides outstanding stability in dimensional accuracy. By the combined use of the measuring unit, troublesome dimensional variations after halting at short intervals can <Test data> #Feed axis thrust: 8126N for both X-axis and Z-axis •Thermal displacement: 05/mi (197/nn.) after cold start 02/mi (79/nn.) after short halting 02/mi (79/nn.) after cycle restart Cutting condition (including halting time of lOsec. for loading/unloading) High-precision turrets with high rigidity To provide both rigidity and accuracy for precision tool indexing, the most advantageous two-piece coupling of large diameter is used for the turret clamping mechanism. The silencing structure of its own minimizes noise during indexing OBy the lubricating oil reclaim system, water-soluble coolant is made long-life. )Cutting chips are efficiently collected through the chute made of stainless steel.
