VOLIS PRECISOIN TEC CO.LTD

VOLIS PRECISOIN TEC CO.LTD has always been researching new technologies ,thus developing the precise, rigidity, and quality devices. Experience in spindle development, foresaw the need for such integrated units, and designed performance units. New products

are interChangeable and very easy to install. With a
range of sizes available in each series.
Recently the performance of machining centers has
been improving rapidly because their users requirements
have become more and more stringent with modern
technological advances. This is particularly true of the
speed of machin-ing center spindles. To meet these
demands, spindles must be designed as integrated units
with simultaneous consid-eration of bearing
specifications, preload, mounting method, lubrication, etc.

High Rigidity
Optimum bearing combinations and preload.

High Accuracy

High precise elements, high running accuracy

and precisebalancing,Negligible vibration.

Stringent Quality control
   Thorough inspections.
   Assured cleanlines.
   Performance accuracy test, pull force test , and run out accuracy    test.

High Speed with Low Temperature Rise
   VOLIS PRECISOIN TEC CO.LTD spindles use angular-contact ball
   bearing with high speed capability.High speed grease or oil-air
   lubrication depending on the speed requirement.

Auto run in test
All VOLIS PRECISOIN TEC CO.LTD spindles tested afterassembled.
“automatic run in test” pertect spindle safe running in the highest speed running time.
