JUKI DDL-900BH

Direct-drive, High-speed, 1-needle, Lockstitch Machine with Automatic Thread Trimmer (Oil Shielding System)

High-speed lockstitch machine with an automatic thread trimmer which is provided with a new oil shielding system. The sewing machine which integrates the direct-drive motor, control box and control panel into a monolithic body is now provided with a new oil shielding mechanism. It not only eliminates oil stains on sewing products, but also further enhances workability and maintainability. In order to prevent oil stains on sewing products, the sewing machine has adopted the “Oil Shielding System” which is integrated into the sewing machine bed. The new structure contributes to the achievement of the maximum sewing speed of 5,000sti/min and also to increased productivity.

“Oil Shielding System”

In order to prevent oil stains on sewing products, the sewing machine has
adopted the “Oil Shielding System” which is integrated into the sewing machine
bed. The needle bar is lubricated with a smaller quantity of oil as compared with
the conventional model. In addition, oil which externally splashes is shielded by
the newly-developed frame oil recovery mechanism and automatic oil circulation
mechanism. The new structure contributes to the achievement of the maximum
sewing speed of 5,000sti/min and also to increased productivity.

Elimination of oil stains on sewing products <Adoption of a oil shielding>

Oil is stored in the oil-shielded made of highly rigid
aluminum die cast which is integrated into the machine
head and provides increased cooling performance. The new
oil-shielded has increased sealing performance as
compared with a plastic oil tank and effectively prevents oil
leakage and tank breakage. Furthermore, as the tank has a
capacity of 600cc, which is equivalent to that of the
conventional model, the frequency of oil replenishing does
not change. These features ensure a reliability of
mechanical parts as high as that of the conventional model.

Oiling and oil-quantity checking can be done with ease

The oil hole is located on the top of the machine arm. The oil quantity can be easily checked with the oil gauge mounted on the top of the bed without tilting the machine head.

Broadened range of adjustment of the hook oil quantity

The adjustable range of the oil quantity in the hook has been broadened to enable fine adjustment. In addition, the bottom of the underside cover contains an oil-quantity adjustment marking which helps prevent oiling errors.
As a result, main tainability is improved.

Highly-functional control panel

The control panel which belongs equivalently to the highly-functional CP-180 family is built into the control box. With this panel, various sewing data ranging from the sewing speed to the production support functions can be adjusted.
In addition, the control panel has been newly provided with a password lock function to restrict panel operation.
The machine may be used simply by entering any given passcode number.

Compact and small energy-saving direct-drive motor

In comparison with the conventional V-belt driven sewing machine, the sewing machine driven by the direct-drive motor saves power consumption by 25%. Furthermore, the new retry control helps increase the material penetrating power of the needle by approximately 10%.
