MAG welding method
The process is easy and precise, leading to significantly increased joint strength. Today, the MAG welding method is the reliable method for joining band saws.
| Strength of base metal | Oxygen + acetylene welding strength | EWG welding strength | |
|---|---|---|---|
| 1 | 150kgf/mm² | 99.5kgf/mm² | 141.7kgf/mm² |
| 2 | 150kgf/mm² | 89.3kgf/mm² | 142.9kgf/mm² |
| 3 | 150kgf/mm² | 109.4kgf/mm² | 140.4kgf/mm² |
* 1, 2, and 3 are data from tensile tests on objects joined by three workers.
1.5 times stronger than oxygen + acetylene; moreover, stable strength is guaranteed regardless of the operator.
The welding process takes only 1/3 of the time needed for manual work. It does not require the same skills as manual work, so joining band saw blades is easy for anyone. It also puts less "strain" on the joints and eliminates the need to pull back and forth, which means less time for rework.
The joints are virtually no "strain" in use, which is a necessity for sawmills where the surface of the sawn timber is important. In addition, the joints do not "crack" at all, which also makes a major contribution to safety.
The machine is equipped with a special grinding machine for finishing joints to improve workability in the finishing process.
To eliminate problems caused by temperature differences during welding, a unique heating process is used to prevent cracking during joining.

The tedious manual strain removal process (horizontal finishing process) that has traditionally relied on handwork has been fully automated. By meticulously quantifying extensive clinical data and incorporating the insights of highly skilled saw doctors, we have achieved an automated strain correction process (horizontal finishing process) equivalent to the expertise of professional saw doctors.
The system fully automates manual strain removal.
Processing the entire area, from the tooth bottom to the back, is possible.
Strain removal processing is performed by adopting an original processing method that is completely different from strain removal processing and applying pressure with concavo-convex rollers, the correction resulted in an exceptionally good finish.
The digital strain display shows the strain on the band saw.
The post-processing control and measuring functions ensure consistent quality.
The band saw has a correction function for changes in hardness and thickness.
Additional tension can be applied if needed.

The system boasts sophisticated, labor-saving, and powerful mechanisms, from stellite welding to finish grinding, all of which are user-friendly in operation.
The very popular SAW-250 is designed to save even more resources and labor by significantly reducing the stellite welding material. In addition, the four-sided design significantly reduces post-processing and polishing time. By using a pulse motor to feed the stellite fusion material, accuracy becomes micron feed, and the introduction of this machine helps to reduce the cost of band sawing and the shortage of skilled labor.

The performance of the TE-250 side grinding machine has been maintained, while a new mechanism has been introduced to reduce the deformation of the cup wheel due to grinding wear.
The new grinding system features a mechanism that allows you to adjust the side saw set angle to suit the material you are machining. The cup grinding wheel slides up from the bottom of the blade to the cutting edge, which gets rid of most of the grinding wheel's dressing work and makes it more efficient. We have also further enhanced saw tooth angle's accuracy.
A high-performance machine that further refines the performance of the TE-250 is now available.

Micro Sharpener
Giken factory, with the GL-100, has developed a stage-of-the-art sharpener that maximizes the performance of narrow band saws blades. This machine stands alone in its class.
With a link type griding wheel lifting device
and an automatic rear feed adjustment device
It uses a direct-coupled type of turning technology to reduce the vibrations and uneven rotation generated by the belt system. This system achieves vibration level V5, and the speed is freely configurable between 100 and 2650 rpm (also available at 100-3460 rpm). Giken's extensive knowledge guides the unique design of the direct-coupled motor.
The powerful link system, which has already proven itself in Giken band saws, shows its direct advantages in the world of fine band sawing: high precision at the high grinding speeds typical of fine band saws, high accuracy, and durability are guaranteed.
This mechanism has transformed the traditional perception of fine bandsaw blades and achieved exceptional precision. In the past, it was impossible to grind all sizes of fine bandsaw blades with a single grinding machine due to the variety of tooth shapes, pitches, etc. In addition, the use of stops and the like forced very unnatural movements and made it impossible to freely adjust the tooth shape. With the development of the universal pitch and universal elevation mechanism, the tooth profile and pitch can be freely adjusted from 1/8 to 7/8 inch, and the original shape of the bandsaw blade can now be selected without the use of stops.
Thanks to the automatic adjustment of the rear feed and the pitch adjustment of the band saw, the rear feed does not have to be readjusted every time the pitch is changed, which is very practical.
Even very narrow band saws are held on both sides, which ensures stable sawing and continuous sawing precision.
The bandsaw, equipped with an integrated stand for mounting on the main unit, allows easy adjustment of very narrow and wide band saws (4 inch) at the touch of a button and stabilizes the feed of the band saw.
To guarantee the durability that is a feature of the Giken grinding machine, the liners A, B, and the razor guide, the feed pins, etc., are made of cemented carbide; the upper part of the frame is made of hardened steel plate, and the nuts of the lifting angle bolts are made of gunmetal and are replaceable. We equip all rotating parts with needle and dust-proof bearings to enhance their durability.
The professional inverter dial panel allows the user to freely adjust the wheel speed and the tooth feed speed and has a tachometer (Hertz counter) and a push-button switch. The control panel is authentic in its user-friendly operation.

Micro Sharpener
The best band saw grinding machine has proven its true sharpness in the world of wood thanks to Giken technology and electronics.
A new mechanism that goes beyond the conventional band saw sharpening machine achieves optimal cutting performance and micro-grinding
It uses a direct-coupled type of turning technology to reduce the vibrations and uneven rotation generated by the belt system. This system achieves vibration level V5, and the speed is freely configurable between 100 and 2650 rpm (also available at 100-3460 rpm). Giken's extensive knowledge guides the unique design of the direct-coupled motor.
We have improved the link-type lifting device, already proven on Giken sharpening machines, to enable even more micro-grinding. This guarantees high strength, precision, and durability.
This mechanism has transformed the traditional perception of band saw sharpener and achieved ease of use and exceptional precision. This device automatically adjusts the tooth depth, tooth feed, and timing of raising and lowering according to the pitch set on the scale. Using the entire cam instead of adjusting the stop enables micro-grinding.
Large eccentric cams can be used in conjunction with fixed handle-type continuously variable pitch adjustment devices for suspension-type tooth feed mechanisms. We've made a large eccentric cam that is 2-5 times the tooth feed stroke and has an ideal cam rotation angle of 180° for tooth feed, 180° for return, 180° for ascent, and 180° for descent. We've also made a cam curve that keeps the tooth feed stable at both the tooth feed point and the end point.
Peripheral dressing with a single stone diamond allows for very efficient use of the grinding wheel, resulting in micro-grinding and greatly prolonging the wheel's lifespan, making it very cost-effective.
The free tooth feed from the inverter, the direct-coupled vibration-free motor, the single-stone diamond dressing for microparticle grinding, and the free rotation setting have all been made very precise and sharp. This machine is the ultimate saw setting machine that the woodworking industry is facing.
Even with high-precision grinding machines in the past, uneven grinding was deemed inevitable due to wheel wear and tear. However, the introduction of the intermediate blade feed system has permanently resolved this issue. Furthermore, with the development of the saw blade support mechanism that prevents saw height and lateral deflection, micro grinding is now possible, and tooth tip accuracy has been further improved.
To guarantee the durability that is a feature of the Giken grinding machine, the liners A, B, and the razor guide, the feed pins, etc., are made of cemented carbide; the upper part of the frame is made of hardened steel plate, and the nuts of the lifting angle bolts are made of gunmetal and are replaceable.

Micro Sharpener
Only the GL-250H can maintain and sharpen band saw blades with KV configured tooth patterns.
The wider gullets of the KV tooth design provide a smooth sawdust discharge. The other KV design features reduce the vibration on the top of the teeth. This significantly improves the productivity and the quality of the cut surface. The GL-250H can be set up for resharpening the KV tooth configuration or either of the straight or round back shaped teeth. You will find this to be a user-friendly, functional and precise band saw resharpener.
The direct connection of the grinding wheel to the spindle motor eliminates any vibration or uneven rotation, unlike belt systems. The rotational speed can be freely selected in the range of 100 to 3,300 rpm.
The powerful-linked lifting device with the direct drive wheel motor is highly durable and enables high-precision cutting.
The fixed handle allows you to adjust pitch and lifting timing with a single touch.
With a single touch, the depth can be adjusted and synchronized with the profile of the band saw blade.
The KV (DIN) blade type, with its low edge vibration and wide blade chamber, improves the durability of the band saw against ground material. It also contributes to energy savings in lumber production.
You can choose between two blade types: straight, back-slotted, and KV (DIN). Cam replacement is also easy.
Dedicated flange makes it easier to change the grinding wheels. In addition, we have eliminated surface and circumference runout when changing.
