We would like to introduce a case where the lifespan of dressers was extended by utilizing high-quality single crystal diamonds from a grinding wheel manufacturer. To maintain high precision, diamond dressers had a short lifespan, leading to high tool costs and the hassle of replacing grinding wheels. Therefore, we analyzed the current dressers with the grinding wheel manufacturer and changed the shape of the single crystal diamond from a prism to a special shape, as well as increased the number of single crystal diamonds for improvement. 【Case Overview】 ■Challenges - Extension of dresser lifespan - Reduction of dresser replacement hassle ■Effects - Improved retention of diamonds, suppressing wear of the tip shape - Significant extension of dresser lifespan *For more details, please refer to the related links or feel free to contact us.

Here is an example of a proposal for improvements to eliminate chocolate stops caused by brush entanglement. In the processing stage of the customer's production line, brushes were frequently getting entangled with the workpieces, leading to frequent chocolate stops. Our company thoroughly investigated the cause in collaboration with our partner companies and proposed standardizing the arrangement of the bristles and the outer dimensions. This resolved the entanglement issue, resulting in zero chocolate stops. [Case Summary] ■ Issues - Thorough investigation and resolution of the cause of brush entanglement - Standardization of bristle arrangement and outer dimensions, extension of replacement intervals ■ Effects - Replacement intervals extended by 250%, reducing running costs - Management of outer dimensions and bristle arrangement has enabled long-term quality stability *For more details, please refer to the related links or feel free to contact us.

We would like to introduce a case where we proposed the design and implementation of an automatic forming machine at our company. In a production line of an automotive parts manufacturer, the person in charge of the grinding wheel forming process retired. However, there was no successor, and they consulted us, stating that there was no time to train someone from scratch. At our company, we are capable of equipment design utilizing the know-how we have cultivated over many years as a tool trading company. We were able to standardize a process that required specialized skills and had become dependent on specific individuals. 【Case Overview】 ■ Issues - Early development of forming technicians - Formulating solutions within a limited timeframe ■ Effects - Standardization of processing quality - Reduction of labor costs through automation *For more details, please refer to the related links or feel free to contact us.

We would like to introduce a case where we achieved a 30-fold extension of the lifespan of end-face grinding wheels compared to conventional methods. In the end-face processing of automotive engine parts, CBN resin bond was traditionally used, but there were challenges due to its short lifespan and the considerable effort required for replacement setup. Therefore, we proposed changing from CBN resin bond to CBN soft metal bond. The results exceeded our goals significantly, to the extent that the customer themselves suggested a price increase. [Case Summary] ■Challenges - Reduction of the effort required for wheel replacement - Reduction of running costs ■Effects - Achieved approximately 30 times the lifespan compared to conventional methods - The results exceeded our goals significantly, prompting the customer to suggest a price increase themselves. *For more details, please refer to the related links or feel free to contact us.

We would like to introduce a case where improvements progressed rapidly through edge analysis using our own equipment. To reduce tool costs, the customer was advancing improvement activities such as extending the life of drills and resolving breakage issues, while searching for solutions. In this context, we conducted edge observation with our measuring equipment and analyzed the welding and wear conditions. The stalled improvement activities began to move forward, resulting in reduced tool costs through extended tool life. [Case Summary] ■Challenges - Resolution of drill breakage due to chip clogging - Reduction of tool costs and drill replacement labor ■Effects - Breakage caused by chip clogging was resolved - Successful improvement of processing conditions, leading to reduced cycle time *For more details, please refer to the related links or feel free to contact us.

We would like to introduce a case where we achieved the development of a groundbreaking grinding belt using a new special raw material that had not been used at all until now. In the process of removing the black scale from the workpiece, we collaborated with our customers to prototype various belts with the aim of improving the grinding power sustainability of the grinding belt. We proposed the use of a special raw material (aggregate) that had not been used before, successfully achieving a significant improvement in lifespan and ensuring stable surface roughness. 【Case Overview】 ■ Challenges - To simultaneously achieve improvements in "grinding power sustainability," "familiarity," and "surface roughness." ■ Results - The birth of a "groundbreaking grinding belt." *For more details, please refer to the related links or feel free to contact us.

We would like to introduce a case where we developed a special flange that allows for the simultaneous use of multiple grinding wheels. The customer's issue was that due to "warpage" and "waviness" in the workpiece, impurities on the surface could not be completely removed in a single processing pass. To address this, we designed a flange that enables the simultaneous use of grinding wheels with different abrasive grains and hardness on a single grinding machine, successfully eliminating the issue of grinding wheel disengagement and removing impurities in one pass. 【Case Overview】 ■ Challenges - Remove impurities in one pass even with workpieces that have "warpage" and "waviness" - Reduce processing time and enhance production capacity ■ Effects - Significant reduction in processing time, successfully enhancing production capacity without additional equipment investment - Contributed to improved accuracy in production planning by clearly establishing a "one pass only" plan *For more details, please refer to the related links or feel free to contact us.

We would like to introduce a case where we achieved the elimination of molded grinding stones for diamond dressers at our company. Due to the instability of the dresser's precision, we were using general grinding stones to shape the dresser itself, which is usually unnecessary and incurs wasted costs. By enhancing the precision of the diamond tip radius and the fixed angle of the diamond, as well as improving the regularity of the diamond arrangement, we improved the quality of the dresser. [Case Overview] ■Challenges - Reduction of the shaping process for the dresser itself - Reduction of dressing frequency ■Effects - Reduced the shaping process for the dresser itself - Shortened the dressing shaping after replacement to 350 times *For more details, please refer to the related links or feel free to contact us.
