Oil leaks and distortion in cast iron gear cases! Cutting of ductile cast iron.

For those troubled by oil leaks due to case surface distortion! We solve this with high-precision lathe and machining processes, achieving improved sealing and zero processing defects.

Do you have any of these concerns? - Oil leaks due to distortion at the gear case joint surface, leading to a backlog of inspection work. - Chipping of cutting tools and variations in dimensional accuracy caused by the unique porosity and hardness irregularities of cast iron. - Excessive unnecessary machining due to full cutting, resulting in increased material costs and processing time. Kyowa Seiki's "Precision Cutting Processing Contract Service for Cast Iron Gear Cases" fundamentally solves these issues. ◇Reducing material loss through effective utilization of black skin with shape proposals◇ We propose a machining plan that avoids full cutting and retains the black skin on areas that do not affect strength. This reduces cutting processes and unnecessary material waste, achieving cost savings. ◇High-precision cutting technology that meets strict geometric tolerances◇ We suppress distortion caused by residual stress in FC and FCD materials, maintaining high standards for surface roughness and flatness at the joint surface. This minimizes the risk of oil leaks and significantly extends product lifespan. ◇Stable mass production system through collaboration between lathes and machining centers◇ Our highly automated processing equipment ensures consistent dimensional accuracy even for cases with complex internal structures. *For more details, please download the catalog or feel free to contact us.

Uneven wear and malfunction of the brake cam | Cutting of mouse and ductile cast iron

For those troubled by uneven wear on cam surfaces and variations in braking! We solve this with robust ductile iron processing, enhancing wear resistance and safety in harsh environments.

Do you have any of these concerns? - Changes in braking feel due to uneven wear on the cam surface from continuous operation, leading to complaints. - Difficulty maintaining the precision of sliding parts due to bending of the shaft section of the camshaft under high loads. - Increased costs due to severe wear of cutting tools as materials become harder to machine to enhance wear resistance. Kyowa Seiki's "Cast Iron Brake Cam Precision Machining Contract Service" fundamentally resolves these issues. ◇ Precision machining that creates smooth sliding surfaces for cam shapes ◇ Our high-precision R surface and curved surface cutting technology reduces friction resistance during operation, preventing uneven wear and supporting long-term maintenance of braking performance. ◇ Distortion suppression approach that brings out the characteristics of FCD material ◇ We minimize distortion that occurs during the machining of ductile cast iron (FCD), which is strong against impact and high loads, ensuring strict dimensional tolerances are met. ◇ Cost reduction solution that retains black skin where appropriate ◇ We propose shapes that leave black skin on non-sliding parts that do not affect functionality. This eliminates unnecessary machining processes and provides affordable, robust components. *For more details, please download the catalog or feel free to contact us.

Failure of roundness in the bearing holder | Cutting of ductile cast iron with a mouse

For those troubled by distortion and unusual noises in housing holes! We solve this with precise inner diameter tolerance processing, preventing bearing play and achieving smooth rotation.

Do you have any of these concerns? - Excessive load on bearings due to inner diameter deformation after press-fitting, causing abnormal noise. - Geometric tolerances (coaxiality, perpendicularity) of cast iron housings not being met, leading to shorter bearing life. - Chucking distortion occurring during machining of thin-walled sections, resulting in high scrap rates due to exceeding dimensional tolerances. Kyowa Seiki's "Cast Iron Bearing Holder Precision Machining Contract Service" fundamentally resolves these issues. ◇ High-precision inner diameter machining that achieves roundness and coaxiality ◇ By employing jigs and machining approaches that consider clamping distortion and deformation from machining heat in cast iron materials, we reliably maintain fine inner diameter tolerances. ◇ Precision lathe technology that prevents deformation even in thin-walled sections ◇ Our unique clamping technology and NC lathe machining significantly reduce defect rates, even for thin-walled shapes. ◇ Reduction of total costs through the utilization of black skin surfaces ◇ We propose blank designs that leave black skin on the outer circumference and non-precision surfaces. This shortens the cutting process while providing high quality at low prices. *For more details, please download the catalog or feel free to contact us.

Wear and impact damage of brake stoppers | Cutting of ductile cast iron for mice

For those troubled by damage and looseness due to repeated impacts! Solve it with precision ductile processing, achieving improved durability and reduced maintenance workload.

Do you have any of these concerns? - The stopper part wears out due to repeated impacts during braking, causing misalignment in the braking position. - Removing the black skin from ductile cast iron is time-consuming, leading to excessive wear of cutting tools. - The positional accuracy of flow surfaces and mounting holes is insufficient, resulting in time spent on fine adjustments during on-site assembly. Kyowa Seiki's "Cast Iron Brake Stopper Precision Machining Contract Service" fundamentally resolves these issues. ◇ FCD Tough Machining Technology That Withstands Impact Loads ◇ Utilizing the properties of high-strength ductile cast iron (FCD), which excels in impact resistance, we perfectly enhance the surface roughness and parallelism of the pressure-receiving surfaces to ensure rigidity. ◇ Cost Reduction Proposal Through Shape Design That Utilizes Black Skin ◇ For non-contact surfaces that do not directly receive impacts, we adopt a machining approach that retains the black skin. This achieves both a reduction in tool costs and a significant shortening of processing time. ◇ Maintaining Positional Accuracy for Mass Production of Various Types ◇ We thoroughly manage the perpendicularity and positional accuracy of reference holes and mounting surfaces using fixed jigs and machining technology, eliminating unnecessary adjustment work on-site. *For more details, please download the catalog or feel free to contact us.*

High load and cracking measures for rear wheel differential cases | Cutting of ductile cast iron and mouse.

For those troubled by damage during high torque or distortion of shaft holes! We solve this with robust FCD precision machining, achieving improved drive transmission efficiency and significant cost reduction.

Do you have any of these concerns? - Cracks around the bearing area and bolt holes of the differential case due to high torque loads on the rear wheels. - Long machining times for large cast iron workpieces, creating a bottleneck in the production line. - Poor yield from large integrated machining significantly increases manufacturing costs. Kyowa Seiki's "Precision Machining Contract Service for Rear Wheel Differential Cases" fundamentally resolves these issues. ◇ Precision machining using FCD material for high load capacity ◇ We use a robust ductile cast iron material that withstands harsh driving torque and perform precision machining without leaving distortions from thick to thin sections. ◇ Cost reduction through an approach utilizing the black skin of raw materials ◇ We propose a machining design that intentionally leaves the black skin surface, which contributes to strength reinforcement. This minimizes the amount of material removed, significantly cutting down on material waste and machining costs. ◇ Reliable technology that guarantees geometric tolerances for shaft holes ◇ We maintain high precision in the coaxiality of shaft holes, which affects the meshing of differential gears. This prevents torque transmission loss and unnecessary vibrations and noises. *For more details, please download the catalog or feel free to contact us.
