OIL MATIC applications

OIL MATIC’s advanced liquid temperature control technologies respond to needs from diverse work fields. OIL MATIC contributes

to stable system operation and improvement in quality and work efficiency.

pplication

“Applications” × “Work fields”

Machining centers

Major heat-

generating components are main bearings

and main spindle drive motors (including built-

motors). OIL MATIC is used for “main spindle cooling,”

which

indirectly cools heat-

generating components by

flowing coolant into a coolant jacket (heat-

exchanging

part).

The “main spindle cooling” includes “jet lubrication”

and

“under-

race lubrication” that lubricate and cool the main

bearings in addition to “spindle core cooling,” which

directly cools inside the main spindle. In any case, OIL

MATIC is widely used.

Other than the above, OIL MATIC is used for “coolant

cooling,” which controls and stabilizes cutting fluid

temperature; “hollow ball screw cooling” for precision

positioning drive; and “linear motor (DD motor) cooling,”

“hydraulic fluid cooling,” and “machine body cooling” to

suppress postural change of a machine body.

Combination machines

There are plural heat-

generating components, such as a

main spindle head (chuck head) and a sub spindle head

for milling and a turret, in combination machines. In

such cases, it is common to indirectly cool the

heat-generatin

g components by flowing coolant by

using OIL MATIC, into plural coolant jackets (heat

exchanging parts) provided for each of the

heat-generating components.

OIL MATIC is also used such as for “coolant cooling” for

stabilizing cutting fluid temperature, “hollow ball screw

cooling” for precision positioning drive of multiple axes,

“linear motor (DD drive motor) cooling,” “hydraulic fluid

cooling,” and “machine body cooling” to suppress

postural change of a machine body.

NC lathes

Major heat-generating components are a

chuck head, which grips workpieces and

tools, main bearings for turret and drive

motors (including built-in motors). It is

common to indirectly cool the heat-

generating

components by flowing coolant into a coolant

jacket (heat exchanging p

art). Also, coolant

cooling which controls and stabilizes cutting

fluid temperature is needed. In any of the

above cases, OIL MATIC is used.

Electrical discharge machine

There are two types of electric discharge

machines; a die-sinking Electric Discha

rge

Machine (EDM) and a Wire Electric

Discharge Machine (WEDM).

Each type uses OIL MATIC to cool machining

fluid (oil or pure water) in a tank called a work

tank, to achieve working accuracy.

OIL MATIC is also used for cooling liquid used

in jet lines.
