Japan SIGA Spindle Unit
6F SERIES PRECISION BORINGSPINDLES
This series is designed mainly for high-speed,high-accuracy and medium-duty finish boring operation. The spindle runs in the 7000 series angular contact ball bearings and NN30K series dou- ble-row cylindrical roller bearings. Although the spindle is lubricated by grease, the spin-dle features high-speed operation that has been conventionally achievable with Micron-Lub lubrication.
7F SERIES PRECISION BORING SPINDLES
This series is designed mainly for high-speed,high-accuracy, and light-duty finish boring operation. The 4F-G gundrilling spindles also use the same structure.
8F SERIES PRECISION BORING SPINDLES (PRODUCTION BY ORDER)
This series uses the 7000 series angular con-tact ball bearings and is used in applications where faster speed and better accuracy are required than those achievable with 6F and 7F series. The same spindle case as used for 6F series is used.
3R SERIES PRECISION BORING SPINDLES
This series is designed mainhly for heavy-duty boring and milling operations. The spindle has two taper roller bearings and two angular contact ball bearings (or two taper roller bearings).Spindle units of Model 3R-30 or larger models have a through hole in the spindle. The units.threaded for inducer installation, designated as Type G, are used for such machining oper- ations as to supply coolant through the tool holder.
4R SERIES PRECISION BORING SPINDLES
This series employs double-row cylindrical roller bearings and double-row thrust angular ball bearings. These bearings, developed as spindle bearings for machine tools, ensure high rotation accuracy, high-speed rotation, high rigidity and low temperature rise with grease lubrication.This series can be used in a wide range of operations from rough boring to finish boring operations. Type G is also available.
Features of Wedge Type Facing Spin-dles
● The stroke is 10 mm or less.
● Backlash between the wedge and slider is less than 0.01 mm.
● The cylinder stroke is 2.14 times the slide stroke, which means easy speed regula- tion and LS adjustments.
● Hydraulic pressure used for actuating the slider should be decreased as low as prac- ticable needed for operation by
installing a reducing valve in the hydraulic circuit since wedge type construction operates the slider by increased force.
7M-F SERIES MILLING SPINDLES
This series is designed mainly for high-speed,high-accuracy, and light-load milling and bor-ing operations. The spindle nose is of NT No. 30 or No. 40 specified by JISB 6101. The arrangement of bearings is identical to that of 7F series spindles.
