Clearance-0 EFF90CZ EFF40CZ EFF15CZ Barrel Finishing
Top Page > Barrel Finishing > New Products >Clearance-0
Patent No.4130922
Patent No.4156315
写真:Clearance-0 Clearance-0 EFF90CZ EFF40CZ EFF15CZ
Expansion of finishing target of workpieces by Clearance-0 Mechanism employment Excellent in high-mix low-volume production of precision workpieces
Benefit
·Clearnace gap between fixed tub and rotating disc is almost Zero.
·Fine and small size of abrasive media can be applied, which can not be applied for conventional model of centrifugal disc finishing machine.
·Fine and small size of workpieces can be finished, which can not be applied for conventional model of centrifugal disc finishing machine.
·Stock removal amount is enhanced by 1.5 times compared to conventional models.

Application
Excellent in deburring and radiusing as well as best suited for heavy cutting to finishing process.

What is Clearance-0
Clearance means the 1-1.5mm gap between stationary tub and roatating disc. In the use of conventional centrifugal disc finishing machine, abrasive media 3 mm or smaller in size can not be applieed, because those media are lodged in the gap. Clearance-0 mechanism has adopted high wear-resistant ceramic ring on rotating disc and stationary tub is mounted on it, which has achieved the clearance almost zero while disc ratates (Patent No. 4130922).
Any kind of finishing condition can be applied because Clearance-0 mechanism allows small size of abrasive media and workpieces, which can not be applied for conventional model of centrifugal disc finishing machine.


Finishing mechanism
 
Water is being supplied to the area of rotation between stationary tub and rotating disc while rotating disc is running, in order to restrain the wear of sliding contact surface between tub and disc.
(1) Supply water into underplate
(2) Once inside of the underplate is filled with water, the water keep on flowing out from sliding contact surfaces to inside the tub.
(3) Start running the rotating disc and supply water into stationary tub from the upper
(4) Overflowed water is constantly drained from the center poll.

Lock Mechanism
On Tilting to Unloading Mass
Stationary tub is automatically locked and tubs are tilted while mass is unloaded.

*Patent No. 4130922(Automatic Stationary Tub Lock Mechanism)


Significant Increase of Stock Removal Amount.
[Stock removal amount is enhanced by 1.5 times compared to conventional models. ]
This line up adopts models with short finishing time and is excellent in high speed operation and stability in finishing ability.It synchronizes Clearance-0 mechanism and enables efficiency of mass production and finishing process.

*1 Stock removal amount is based on comparison by 30 minutes finishing.
Basic test piece of Tipton Corp and ratio of conventional EFF40R is supposed to be 100.
*2 Workability of the machine is "stock removal amount / wearing ratio" of abrasive media




Example of Establishment of Automated System
EFF15CZ System(Patent  No.41562315)


Five Benefits of The System
 
Five Benefits of The System
(1) Clearance-0 Machine
Applicable to small precision parts, abrasives, very small abrasive media which are unable to be used in conventional models.
(2) Small Sized Parts and High-Mix Low-Volume Productions Applicable.
Applicable to high-mix low-volume productions by stocking 2 kinds of abrasive media and allocating 2 replacable separators.
(3) Application for IN-Line
Abrasive media and workpieces are circulated in the unit by small bascket.
Just customising loading and unloading parts, it is applied to IN-Line layout.
(4) High Operating Ratio
By stocking 2 tubs of abrasive media, it enables separation process of previous batch and preparation of next batch. Centrifugal disc finishing machine stops only while loading mass and it achieves high operating ratio.
(5) Small-Footprint
It achieves small-footprint system which is adjusted for compact centrifugal disc finishing machine and save small-footprint demention of machine itself.
