THE LATEST SERIES LBS-N THE INCREDIBLY HIGH CUTTING ACCURACY GUARANTEES SUPERB PRODUCTS IN CLOSED FORGING AND COLD FORGING OF POST STAGES.				The Manyo's concept with cutting machines is this: 1. Mechanism of machine body 2. Mechanism of cutting tools 3. Mechanism of material feed A cutting machine is fully satisfactory only when it is provided with the above mentioned three elements perfectly and permits these to act organically cooperatively. With these as the three major principles in design and engineering, Manyo is constantly challenging to develop steel cutting and shearing machines by the full utilization of its technology and experience.
These are the latest models of billet cutting machines designed and engineered by MANYO to offer functional advantages in hardware including the accuracy of cutting, the durability and rigidity of the machine, the lessened manpower in tool changing, the automation of set-up changing with a change in material sizes and the ease of maintenance plus many advantages in software including noise prevention and various safety measures.

THREE IMPORTANT FEATURES OF SERIES LBS-N [UNEXCELLED BY ANY OTHER SIMILAR MACHINES]
1. FEATURES IN MECHANISM OF MACHINE BODY 12 PATENTS PENDING
Unlike machines that develop pressure directly with cranks, the patented lever mechanism incorporated with this machine determines the lowest (weakest) point of the pressure as its nominal capacity so that the normal pressure is generated in any position from the top dead center down to the bottom dead center. This makes the machine ideal for use in such a job like cutting where the maximum tonnage is require upon contacting of the upper blade with the work. The connecting parts of the ram and the lever are designed to withstand the backlashes that take place during cutting. Since the impact of cutting is relieved by the lever before it reaches the crank, the machine is kept free from undue load and the cutting blades will last longer. The frame is of welded construction using extremely heavily gaged steel plates. The lever, ram and other important parts are made of cast steel and the shafts such as king pins are made of premium quality refined alloy steels. These provide high rigidity and impact strength to the machine. The C-type frame permits easy operation from three ways and facilitates changing of blades. The “mouth opening” which is a disadvantage of conventional C-type frames is completely eliminated by the original design that incorporates the frame and lever having exceptionally high rigidity. All the driving parts are built in the thick-walled frame to offer noise-free and safe operation. The connecting parts for the gear wheel, lever and crank are immersed in the oil bath and the other slideways are automatically lubricated, so there is no need for oiling and greasing. A high performance air friction type is employed for the clutch brake. The linings withstand considerably long-term use. Large-scale foundation work is not required because the machine has a stable center of gravity and is of floor installation type. The machine is designed and equipped to meet the requirements specified in various safety codes and standards.

2. FEATURES IN MECHANISM OF CUTTING TOOLS 11 PATENTS PENDING
The restrained cutting system which is the result of many years of our researches provides neat cutting sections. for example, the machine can cut S45C at a sharp angle of 1° with volume errors of less than ± 0.5%. This cutting method permits smooth continuous operations in single row backward extrusion type heating furnaces and high frequency heating furnaces for heating operations or with transfers and automatic hands. This contributes to the production of superior forged products. The die sets that hold the upper and lower blades and the stopper are made of cast steel to have robustness and to maintain high cutting accuracy even after long-term use. The liners of special steel provided to the working surfaces of the tool holders that receive the highest pressure enable the blades to be maintained in a stable state at all times. They serve also to maintain cutting accuracy and to protect the blades against damages. An air detection system is incorporated for the stopper to assure fail-proof detection of material. It is devised not to leave flaws by permanent strains, burrs and scratches on the end faces of the work. The cassette holder system that houses the upper and lower blades in one blade casing permits one-touch exchanging of the upper and lower blades. This coupled with the features of the C-type frame makes possible the jiffy exchanging of the blades. The cutting blades will be manufactured by forging the special steel specifically ordered by you and finishing these by meticulous heat treatments. the blades feature particularly high abrasion and impact resistances and these coupled with the features of the pressurizing mechanism incorporated to the machine body eliminate the possibility for cracking and chipping at all, thus assuring the long life of the blades. Three edges of the lower cylindrical blade can be used by rotating the blade. When the edge is reground, additional cuts can be obtained in the longitudinal direction of the blade, so there is no waste. The upper flat blade can be used effectively on 8 edges - top, bottom, right, left, front and rear (optional).

3. FEATURES IN MECHANISM OF FEED 3 PATENTS PENDING
The special pinch rollers designed to apply axial restraining forces exert powerful compressive forces upon the work and eliminate the buckling of the work. Cutting with higher accuracy is made possible by these. The special pinch rollers of a self-aligning system do not require any adjustment with the change in material sizes at all. The material surfaces have no roller flaws at all, thanks to intermittent feeding. The material feed rollers made of hardened special steel offer markedly improved abrasion resistance. Provision of tension devices in various parts of the chains for driving the material feed rollers permits noise and vibration free conveyance. The material receiving dampers provided with the feed mechanism prevent the impact sound of dropping when the material is transferred from the stand onto the material feed rollers.

NUMERICAL CONTROL TECHNOLOGY IN WHICH MANYO IS TOPS. NC CONTROL (ECO-F2)
The NC control unit developed by Manyo for exclusive use with choppers is standard equipment with Manyo Steel Choppers Series LBS-N. This unit offers various operations with less manpower.
STANDARD SPECIFICATIONS OF ECO-F2 (5 PATENTS PENDING)
ECO-F2 PROVIDED WITH SERIES LBS-N MACHINES AS STANDARD EQUIPMENT CAN DO THESE. DIGITAL CUTTING TO STANDARD SIZES AUTOMATIC TERMINATION AND INITIATION SELF-ALIGNMENT OF MATERIAL FEED ROLLERS You set a desired cutting length on the control board and turn the button on, then the machine cuts the materials to this set size and discharges the cut materials automatically. The unit judges the terminal and initial parts of the work that can be the cause for the irregularity in weight and instructs the machine logically to cut these off. The unit adjusts the height of the material feed roller devices automatically. You simply set a material diameter value on the control board and press the button. the feed rollers align their centers of themselves.

	ADDITION O THESE SPECIAL SPECIFICATIONS TO STANDARD ECO-FI WILL MAKE THE MACHINE ADAPTABLE TO WIDER JOBS. AUTOMATIC CLAMP FOR CUTTING BLADES (TYPE ECO-FI001) MEASUREMENT OF MATERIAL DIAMETERS (TYPE ECO-FI002) WEIGHT ASSORTMENT OF CUT MATERIALS (TYPE ECO-FI003) This clamp puts the blade holder housing the upper and lower blades into the machine or removes it from the machine automatically. By the instruction of buttons, the hydraulic campers clamp the upper and lower blades respectively. this is recommended particularly for large sized machines. This system is designed to measure the errors in the diameters of the material, and cuts the material while adjusting the standard size stopper automatically. The result is much higher accuracy of weight. (The accuracy of diameter measurement: 1/100) This system detect the micro weight errors of the cut materials and assorts the materials automatically. Since the materials are assorted by range, the efficiency is extremely high. (Assortment accuracy ±2.5 g)
