Speed IncreaserPAT.RPMPatented; USA, Canada, Germany, UK,France, Italy, and South KoreaRHigh Spindle improves drilling andend milling performance on existing machines bymultiplying the spindle speed 4, 5, or 6 times.27SPINDLE SYSTEMPAT.DUAL CONTACTUS Patent No. 5352073
Obtain optimum cutting tool performanceHigh efficiency cutting tools have been developed for advanced highspeed machining. HIGH SPINDLE maximizes performance of thesecutting tools by increasing the spindle speeds up to higher requiredlevels.HIGH SPEED MACHINING INCREASESPRODUCTIVITY WITH GREATER ACCURACYAND SUPERIOR FINISHReduce load to machine spindleContinuous use at high revolutions results in shorter life span of themachine spindle due to excessive load to its motor and bearings. HIGHSPINDLE reduces this load and greatly extends the life of theexpensive machine spindle.Reinforced gear driving systemThe planetary gears, which havebeen constantl y up-graded sincethe development of our first "HighSpindle" back in 1970, achievessmooth operation with minimal heatgeneration and hightorque transmission.BIG-PLUS is standard on all BT & CV Taper versionsPAT.PAT.Simultaneous taper and flange contact between machine spindle andtoolholde r provides improved rigidity and AT C repeatability .Interchangeability with conventional spindles ensures suitability for yourexisting machines.High precision collet chuck systemCONVENTIONALClearanceBIG-PLUSSPINDLE SYSTEMFITThe BIG New Baby Collet isworld renowne d for itsunmatche d accurac y andprecision.It offers concentricity close tosub-micron.ColletClassRigidity increased 1.7 timesLarger diameter body andspindle with double angularcontac t bearing s andreinforce d locatin g pinassembly greatly increasesrigidity.ModelBBT40-GTG5-10-140-65BBT50-GTG6-10-158-80BBT50-GTG4-16-177-80.00004" at nose[NEW BABY CHUCK]L(Inch)7.8748.6619.449.00004" .00012"At nose4xdMax.
