All of our conveyors and coolant tanks arecustomized to individual customers’ needs
There are no “standard products” in our lines of chip conveyors and coolant tanks. We
manufacture products according to customers’ usage conditions and the installation
environment.
HAKUSANKIKO CO., LTD. began manufacturing chip conveyors in 1982. In accordance withthe progress of machining tools and processing technology, the requirements for thefunctions and performance of chip conveyors have changed greatly and we have been
constantly engaged in product development and improvement to respond to these changes.
We have long been recognized as a leading chip conveyor manufacturer thanks to our trackrecord and know-how accrued over forty years, skilled engineers, and our all-in-one facility
also be relied on to solve any issues regarding chips and coolant.

TWO-STAGECONVEYOR

Two-stage conveyors combining
the advantages of floor conveyors
and scraper conveyors
Suitable for removing mixturesof long and small chips
MECHANISM

Type: Chip conveyor

A two-stage conveyor combining a floor conveyor and scraper
conveyor, which are suitable for transferring long chips andsmall chips respectively. It can remove mixtures of various
shapes of chips reliably.
First the upper floor conveyor removes long chips and then thelower scraper conveyor removes any remaining small chips.
When high filtration performance for coolant is required, a drum
filter can be incorporated into the lower scraper conveyor.

Two-stage conveyors with a drum filter
Two-stage conveyors with/without a drum filter are available

Needle-shaped chips from gear-cutting machinesand broaching machines
・Scale-shaped chips from multi-axis machines andspecial-purpose machines
・Curled chips shorter than 100mm

MECHANISM

COIL CONVEYOR
SCREW CONVEYOR
Type: Chip conveyor

Space-saving chip conveyors withsimple structures that can be installedin small spaces such as insidemachining tools
Installation inside machines
APPROPRIATE USES ・・Short-distance transfer in a small installation space

Coil conveyor mechanism
・Chips are transferred by the rotation of coils
・Suitable for long curled chips

In contrast to screw conveyors, coil conveyors have no shaft, meaning a large
amount of coolant can flow through.

Screw conveyor mechanism
・Chips are transferred by the rotation of a spiral blade attached to a shaft
・Suitable for granular chips and short curled chips

In contrast to coil conveyors, screw conveyors have no open space at their center,transferring chips more efficiently with less return.
