Here is a case study of Company B, which adopted Arus's "powdered high-speed steel." The company was using high-speed steel blades for their stainless steel sheet cutting machines, but they were spending a lot of time on blade replacements and were looking for a method that would allow for quicker changes. In response, Arus proposed a method to "introduce highly durable blades and reduce the number of replacements themselves." By implementing our highly durable "powdered high-speed steel," although the unit cost per blade increased, the annual number of blade replacements was reduced from 48 sets to 4 sets, shortening the replacement time by 92% and cutting overall costs by approximately 75%. 【Implementation Effects (Excerpt)】 ■ Blade Replacement Time (i.e., Line Downtime) - Before Implementation: 12 replacements in 3 months (once a week) @ 30 minutes × 1 set × 48 times a year = 24 hours - After Implementation: 1 replacement in 3 months @ 30 minutes × 1 set × 4 times a year = 2 hours → ▲22 hours (approximately 92% reduction in replacement time) *For more details, please refer to the PDF document or feel free to contact us.

Here is a case study of Company A that adopted Arus's "powdered high-speed steel." The company was using high-speed steel blades in their rubber sheet cutting machines, but due to the lack of durability of the blades, they spent a lot of time on blade replacements and were exploring ways to extend the lifespan of the blades. In response, Arus proposed a method to "introduce highly durable blades, extend the lifespan of the blades, and reduce the frequency of blade replacements." By introducing our highly durable "powdered high-speed steel," although the unit cost per blade increased, the annual number of blade replacements was reduced from 360 to 30, cutting replacement time by 92% and overall costs by approximately 61%. [Implementation Effects (Excerpt)] ■ Blade Replacement Time (i.e., Line Downtime) - Before Implementation: 12 replacements per day @ 15 minutes × 1 blade × 12 times per day × 30 times per year = 90 hours - After Implementation: 1 replacement per day @ 15 minutes × 1 blade × 1 time per day × 30 times per year = 7.5 hours → -82.5 hours (approximately 92% reduction in replacement time) *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce a case study from Company M, which adopted Arus's "replaceable blade system." The company was sourcing blades from overseas due to their machinery being imported, but the lost-wax integrated blades were very expensive and had a lead time of over three months, which was problematic. In response, Arus proposed a replaceable blade system that separates the blade from the holder, using a material that is resistant to chipping. By introducing the replaceable blade system, the unit cost of the blades decreased, and when they wore out, only the blades could be replaced while keeping the holder intact. By using a more chip-resistant material, the lifespan was extended, resulting in an overall cost reduction of approximately 78%. 【Implementation Effects (Excerpt)】 ■ Blade Replacement Time (i.e., Line Downtime) - Before Implementation: Replaced every 3 days, 15 minutes × 80 times a year = 1,200 minutes = 20 hours - After Implementation: Replaced every 5 days, 15 minutes × 48 times a year = 720 minutes = 12 hours → Reduction of 8 hours (60% reduction in replacement time) *For more details, please refer to the PDF document or feel free to contact us.

We will introduce a case study of a company that implemented changes to the "milling cutter" and cutting method proposed by Arus, achieving a reduction in processing time and cost savings. To companies using milling machines: Are you facing these concerns? - I want to shorten processing time even more. - How can I reduce costs? The company was engaged in grinding rubber-related products using diamond grinding wheels. They were seeking to shorten processing time and reduce tool costs. In response, Arus proposed a "special milling cutter with high cutting capability," achieving a significant reduction in processing time and tool costs at a processing speed four times that of conventional methods. As a result, there was a total cost reduction of 39%. *For more details, please refer to the PDF document or feel free to contact us.

This time, we would like to introduce a case of providing harvesting blades for the "automatic harvesting robot for mini tomatoes." In 2020, Ars's harvesting blades were adopted for the automatic harvesting robot for mini tomatoes. Initially, the implementing company planned to develop an automatic harvesting robot, including a dedicated blade, but faced difficulties in designing the scissors. The scissors are double-edged, making them more challenging to design compared to single-edged knives or kitchen knives. The implementing company decided to forgo in-house development and requested our company, a manufacturer of agricultural and horticultural blades, to develop the dedicated blade.

●What is a carbide round knife? A carbide round knife is made from a super hard alloy created by sintering powdered hard metal carbide. Due to its significantly higher hardness compared to iron-based metals, it can greatly reduce the frequency of blade replacements and line stoppages caused by wear. Under optimal cutting conditions, it boasts over 20 times the durability of commercially available products (according to our own research). Additionally, the round knife can be used immediately by simply clamping it in a holder, as it cuts using only rotational motion. This makes it easy to incorporate into designs and equipment. It can also be attached to commercially available cutters and machines, so we encourage you to give it a try. We can provide immediate delivery from just one piece! ●Where is it used? - Cutting rubber products containing reinforced fibers (aramid fibers) - Cutting rubber sheets - Cutting resin sheets - Cutting packaging films, etc. The industries are diverse, including food packaging and medical applications! Our cutting tools are tailored to the material to be cut, providing suitable blades in terms of material, shape, and angle.

We would like to introduce a case where we received a consultation from a machinery manufacturer regarding the issue that "the durability of the cutting blade is poor, and when the blade edge wears down, it tends to leave uncut areas." Our company manufactured the blade material using cemented carbide and created fine grooves on the sliding part of the blade to allow for shallow edge contact, enabling the cutting of the workpiece. As a result, we improved the durability of the blade itself and made it less likely to leave uncut areas, ensuring reliable cutting. 【Case Overview】 ■ Issues - Poor durability of the cutting blade - Tendency to leave uncut areas when the blade edge wears down ■ Processing Details - Blade material made of cemented carbide - Fine grooves created on the sliding part of the blade *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case study on the production of a "non-woven fabric fiber machine shear-type cutter." We received inquiries about improving the sharpness and durability of the blades used in fiber machines for the continuous cutting process of non-woven fabrics. In particular, there were concerns that fibers tend to get caught between the blades, affecting the stability of processing quality. To match the properties of non-woven fabrics, we adopted blades made of a material with superior wear resistance. Additionally, to ensure that fibers can be cut reliably, we performed back grinding with a slight curvature on the back of the blades and made appropriate tightening adjustments. [Challenges] ■ We want to improve the sharpness and durability of the blades used in fiber machines for the continuous cutting process of non-woven fabrics. ■ There are concerns that fibers easily get caught between the blades, affecting the stability of processing quality. *For more details, please download the PDF or feel free to contact us.

We received an inquiry about the scissors-type blade used for continuously cutting the ear straps of masks in non-woven fabric mask manufacturing machines, and we would like to introduce a case we have developed. The conventional blades had issues with low durability and were prone to leaving uncut sections. Therefore, while maintaining the conventional shape, we improved the blade shape and material. For the blade material, we adopted a steel type with excellent wear resistance and adjusted the shape so that the upper and lower blades of the scissors make proper point contact, enhancing cutting performance and extending lifespan. 【Case Overview】 ■Issues - Conventional blades have low durability - Prone to leaving uncut sections ■Processing Details - Adopted a steel type with excellent wear resistance for the blade material - Adjusted the shape for proper point contact between the upper and lower blades of the scissors *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where we addressed concerns regarding cutting uncured rubber and raw rubber. This time, the consultation was about rubber in a sheet form. Uncured rubber has a high viscosity, making it prone to deformation, and when cut by sliding, there is a tendency for the workpiece to stick to the blade. Using a Thomson blade for a push-cut or pressing a round blade against it are effective methods. Additionally, it is important not to apply excessive force. By applying a fluorine-based resin coating to the blade, the release properties are improved, resulting in cleaner cut surfaces. 【Case Overview】 ■ Issue: Prone to deformation and tendency for the workpiece to stick to the blade when cut by sliding ■ Processing Details: Coated the blade with a fluorine-based resin ■ Result: Improved release properties, resulting in cleaner cut surfaces *For more details, please download the PDF or feel free to contact us.

Here is an introduction to a case where we manufactured and delivered an octagonal blade for cutting non-woven fabric used in textiles. In textile cutting applications, there are more examples of using round blades, but by using a polygonal shape, the blade engages more with the fibers, increasing straightness and allowing for more efficient cutting. In the case of polygonal blades, each edge needs to be sharpened individually, but we can accommodate special sizes and shapes. We can suggest blades suitable for your needs and applications, so please feel free to contact us with your requests. 【Case Overview】 ■ Product: Octagonal blade with an outer diameter of over 200φ ■ Purpose: Cutting non-woven fabric used in textiles *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case of a custom-made large scissors-type cutting cutter designed for cutting non-woven fabric. Non-woven fabric has fibers oriented in various directions, making it easy for force to be dispersed. Therefore, we designed it to cut with point contact. The blade length is approximately 250mm, allowing for smooth cutting of wide workpieces. In addition to the scissors-type cutter, we offer a variety of blades including saw blades, round blades, and slide cutters. If you could provide us with the main application and installation dimensions, we will take care of the detailed selection. 【Case Overview】 ■ Product: Large scissors-type cutting cutter (blade length approximately 250mm) ■ Purpose: Cutting non-woven fabric ■ Result: Smooth cutting of wide workpieces is possible *For more details, please download the PDF or feel free to contact us.

We would like to introduce a production example in response to your inquiry about wanting to create perforations at a specified pitch on the edges of film packaging. Since it was required to be in a state that could be easily torn by hand rather than completely cut, we proposed a round blade type perforation cutter that can be adjusted according to the thickness and material of the film. The blade is designed with protrusions at regular intervals, allowing for uniform perforations on the film simply by pressing it against the surface. 【Case Overview】 ■ Product: Perforation Cutter ■ Purpose: To create perforations at a specified pitch on the edges of film packaging ■ Result: Achieved a specification that allows for uniform perforations on the film just by pressing it against the surface *For more details, please download the PDF or feel free to contact us.

We would like to introduce a production example in response to your inquiry about wanting to simultaneously cut both ends of a bag in a jagged manner while also performing notch processing. To achieve deeper cuts during the cutting process with the saw blade that our existing users have been using, we proposed a configuration that includes an additional notch cutter. This time, to facilitate maintenance of the blade tip, we manufactured it as a removable type, but an integrated version is also possible. 【Case Overview】 ■ Issue: Wanting to cut both ends of a bag in a jagged manner while also performing notch processing simultaneously ■ Processing Details: Additional installation of a notch cutter to the saw blade (removable as well) *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where we received a request from a fiber machinery manufacturer to produce and deliver a circular blade for cutting cushioning material for packaging all at once. Since the workpiece was made of thick kraft paper, we arranged the saw blades in a V-shape to reduce the resistance on the blades compared to a straight alignment, thereby improving the penetration into the workpiece. Although the increased blade length affects the stroke length of the cylinder, this method is sometimes used for workpieces such as coated paper. 【Case Overview】 ■ Purpose - To cut cushioning material for packaging all at once ■ Processing Details - By arranging the saw blades in a V-shape, we reduced the resistance on the blades compared to a straight alignment, improving the penetration into the workpiece. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case study in response to the inquiry regarding the high wear rate and frequent blade replacements of existing circular blades when cutting rolls of copper foil film at various stages of processing. We propose a carbide circular blade made from ultra-fine particle alloy, featuring a double-edged design. By altering the cutting angle at the start and the angle at the blade's base, we have reduced the impact on cutting performance even as the blade wears, enabling stable cutting even with composite materials. As a result, we have achieved more than double the lifespan compared to conventional blades, thereby reducing the frequency of replacements. [Case Overview] ■ Issue - Existing circular blades wear out quickly, leading to high replacement frequency. ■ Proposal - A carbide circular blade made from ultra-fine particle alloy with a double-edged design. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case study in response to the request to minimize the irregularities on the cutting surface during the process of cutting thin film used for solar panels into long lengths. We selected a long-lasting, high-hardness carbide circular blade and adjusted the blade angle and thickness to suit the workpiece, allowing for cutting without applying unnecessary stress to the film. Since the sharp edge is maintained even during continuous cutting, the cutting surface can be kept clean. This method can also be applied to other functional films (such as PET and EVA). 【Case Overview】 ■ Challenge - To minimize irregularities on the cutting surface during the process of cutting thin film into long lengths. ■ Processing Details - Selected a long-lasting, high-hardness carbide circular blade. - Adjusted the blade angle and thickness to suit the workpiece, allowing for cutting without applying unnecessary stress to the film. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case in which we received an inquiry from a medical device manufacturer regarding the desire to "cut a silicone tube with a diameter of less than 1mm, without burrs, and at an angle." The tubes used for catheters are extremely thin and are inserted into narrow internal pathways such as blood vessels, making them critical components that require high safety standards. An angled cut expands the cross-section, so the thickness of the blade and the angle of the cutting edge are directly linked to the quality. In response, we proposed a thin-blade design of a carbide round blade, which achieved an extremely smooth cutting surface while suppressing deformation of the tube. Additionally, the use of carbide material significantly improved the durability of the blade. 【Case Overview】 ■ Challenge: To cut a silicone tube with a diameter of less than 1mm, without burrs, and at an angle ■ Proposal: Thin-blade design of a carbide round blade ■ Processing Details: Achieved an extremely smooth cutting surface while suppressing deformation of the tube ■ Result: The use of carbide material significantly improved the durability of the blade *For more details, please download the PDF or feel free to contact us.

We received an order for round blades for slitting processing for food protection sheets, and we would like to introduce a case we produced. After much trial and error, we decided to use round blades for this slitting process and opted for carbide materials to enhance durability compared to conventional methods. Considering the installation dimensions of the machine and the size of the slits, the final diameter was reduced to less than 20mm. For reference, a PET bottle cap has a diameter of about 28mm, making this even smaller. 【Case Overview】 ■ Purpose: Slitting processing for food protection sheets ■ Processing Details: Use of carbide materials ■ Product: Ultra-small round blade with a diameter of less than 20mm *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where we received a request from a food manufacturer to produce and deliver a carbide round blade for slicing processed meat.
