A gear refers to a mechanism that transmits power through continuously interlocking teeth. Other transmission methods include chains and belts, but gears are a reliable and powerful means of transmitting force, excelling in their ability to transfer power smoothly without slipping. Additionally, by changing the shape, pitch, and number of teeth of the gear, it is possible to adjust the range of power transmission, rotational speed, and torque, making them applicable in various machines. *For more details, you can view the related links.

"Gears" are essential components for transmitting power in machinery and are widely used in various industries. In recent years, the demand for quiet gears and gears with high transmission efficiency has increased due to the proliferation of collaborative robots, automated transport equipment, and the emergence of electric vehicles. To improve quietness and transmission efficiency, methods such as reducing the shape and pitch errors of gear teeth and eliminating unnecessary irregularities on the tooth surface to enhance surface roughness are mentioned. To manufacture gears with high shape precision and smooth tooth surfaces, "gear grinding" is performed. *For more detailed information, please refer to the related links.

A helical gear is called "hasuba" in Japanese. While a spur gear, which is commonly imagined as a gear, has straight teeth, a helical gear has spiral-shaped teeth, giving it an appearance of being cut at an angle. For this reason, it is referred to as a helical (hasuba) gear. *You can view the detailed content of the column through the related links. For more information, please feel free to contact us.*

We would like to introduce a case study on the process design for stress reduction that we conducted. When machining a deep V-groove shape into round bars, deformation due to stress occurred after rough machining using wire cutting, making the finishing process impossible. We left extra material at the tip of the V and connected it with a bridge, allowing us to perform the finishing process while suppressing deformation due to stress. Finally, we cut off the bridge section to complete the V shape. 【Case Overview】 ■Challenge When machining a deep V-groove shape into round bars, deformation due to stress occurred after rough machining using wire cutting, making the finishing process impossible. ■Results - Left extra material at the tip of the V and processed while connected with a bridge. - Finished machining with a small-diameter end mill after the rough machining process using wire cutting. - Cut off unnecessary parts to complete the work. *For more details, please visit our website or feel free to contact us.

We would like to introduce a case where quality improvement was achieved through engineering enhancements. The material is A2017. The red-framed area is prone to distortion due to machining stress, and during the initial production, there were many out-of-tolerance defects in strict tolerance areas such as parallelism of 0.02, height of 15 +0.02/0, and hole position of 8.3 +0.02/0, resulting in a significantly poor yield. As a countermeasure, we proposed annealing treatment. By performing annealing treatment on the material before machining, there was an additional cost for the treatment, but we were able to reduce distortion, which led to a decrease in defects, allowing us to deliver stable quality to our customers. [Challenges] ■ The material is A2017, and the red-framed area is prone to distortion due to machining stress. ■ There were many out-of-tolerance defects in strict tolerance areas, resulting in a significantly poor yield. *For more details, please visit our website or feel free to contact us.

We received a consultation from the manufacturer regarding the improvement of safety during assembly work, and we would like to introduce a case where we changed the shape of the counterbore hole to prevent tearing. In a flange-shaped part, the counterbore hole for the fixing bolt interfered with the center hole and became dangerously thin and knife-like, raising concerns about deformation and other issues. We modified the counterbore hole for the fixing bolt by cutting it into a U-shape towards the center hole, ensuring that no thin, knife-like edges remained. [Case Overview] ■ Issue: The counterbore hole for the fixing bolt interfered with the center hole, creating dangerously thin, knife-like edges and raising concerns about deformation and other issues. ■ Result: The counterbore hole for the fixing bolt was cut into a U-shape towards the center hole, eliminating any thin, knife-like edges. *For more details, please visit our website or feel free to contact us.

Here is an example of a product made from iron-based material with a threaded hole processed on the end face, which undergoes a plating process. When immersed in the liquid, the interior of the bag-shaped threaded hole becomes an air pocket, preventing the plating solution from circulating, resulting in a thin film forming inside. In such cases, due to insufficient plating, rust begins to develop from the back of the thread over time. By drilling through the pilot hole of the bag-shaped threaded hole at a 90° angle, air pockets are eliminated in the threaded section, allowing the plating solution to circulate. This not only ensures proper plating inside the threads but also suppresses rust formation over time. [Issues] - When immersed in the liquid, the interior of the bag-shaped threaded hole becomes an air pocket, preventing the plating solution from circulating, resulting in a thin film forming inside. - Due to insufficient plating, rust begins to develop from the back of the thread over time. *For more details, please visit our website or feel free to contact us.*

Here is a case study on reducing processing time through balance cutting in NC lathe machining. The material is SUM23, with a material diameter of φ30, and the distance from the protrusion to the base is 102mm, while the neck diameter is φ23. In this product, the protrusion is SRφ4.5, and when taper machining is done with a comb blade, the longer the protrusion, the more the number of cuts increases, leading to longer processing times. By synchronizing the comb blade and turret of the NC compound automatic lathe to perform balance cutting, rough and finish machining were done simultaneously. This allowed for larger cutting amounts in a single pass, reducing processing time to less than half of that of conventional cutting. [Case Summary] ■Challenge When the protrusion is SRφ4.5 and taper machining is done with a comb blade, longer protrusion leads to an increase in the number of cuts, resulting in longer processing times. ■Result By synchronizing the comb blade and turret of the NC compound automatic lathe to perform balance cutting, the process was shortened, and larger cutting amounts could be achieved in a single pass, reducing processing time to less than half of that of conventional cutting. *For more details, please visit our website or feel free to contact us.

We would like to introduce a case where cost reduction was achieved through a change in material. When the material is SGD400 and the treatment is electroless Ni5μ, it involves iron material plus surface treatment (plating). In the process, plating occurs after machining. Due to the outer diameter dimension tolerances of the product, it may not fit standard material sizes, resulting in additional costs for material fabrication or outer diameter machining. By changing the material to SUS303 and the treatment to degreasing, we were able to eliminate the plating process intended for rust prevention. This absorbed the increase in material costs for stainless steel and achieved overall cost reduction.

We would like to introduce a case where the hexagonal head corner R0.2 was changed to an arbitrary R to achieve cost reduction. Typically, when there is an R dimension indication on the hexagonal head corner, it is necessary to change the grip within the machining machine and perform end milling on the hexagonal shape and corner R from the end face side. By changing the hexagonal head corner R from a dimension indication to an arbitrary R, it becomes possible to process the hexagonal shape from the cross direction, and since the corner R is also arbitrary, it can be finished using turning processing. [Challenges] ■ When there is an R dimension indication on the hexagonal head corner, it is necessary to change the grip within the machining machine, requiring end milling on the hexagonal shape and corner R from the end face side. ■ Even when using a multi-tasking lathe, it is limited to machines with a turret. *For more details, please visit our website or feel free to contact us.

We would like to introduce a case where cost reduction was achieved through a change in material. The instructions at the time of estimation specified material S45C, outer diameter Φ6f8(-0.010/-0.028), and surface treatment of hard chrome plating of 10μm or more. According to these instructions, the process would be as follows: 【Cutting blank (Material D)】 ⇒ Pre-treatment grinding ⇒ Surface treatment ⇒ Post-treatment grinding finishing. By changing the material from S45C to stainless steel, we proposed eliminating the need for grinding before surface treatment. By suggesting a material change based on the intended use, we can reduce processes, shorten lead times, and achieve cost reduction. 【Challenges】 ■ The instructions at the time of estimation specified material S45C, outer diameter Φ6f8(-0.010/-0.028), and surface treatment of hard chrome plating of 10μm or more. ■ The processing steps according to the instructions would be: 【Cutting blank (Material D)】 ⇒ Pre-treatment grinding ⇒ Surface treatment ⇒ Post-treatment grinding finishing. *For more details, please visit our website or feel free to contact us.

We would like to introduce a case where we achieved reductions in construction time and costs through engineering streamlining. The manufacturing process for the customer's design involves three steps using chromium-molybdenum steel (raw material): cutting process (rough) → heat treatment (quenching) → cutting process (finishing). Our proposed manufacturing process changes the material to heat-treated stainless steel (quenched material) and consists of only one step, performing both rough and finishing cutting processes. Despite a slight increase in material costs, we achieved significant cost reductions and shortened the construction period by consolidating the rough and finishing processes and eliminating the heat treatment step. 【Case Overview】 ■Challenge: Three steps of chromium-molybdenum steel (raw material) → cutting process (rough) → heat treatment (quenching) → cutting process (finishing) ■Results - Changed from chromium-molybdenum steel (raw material) + heat treatment to heat-treated stainless steel, modifying the separate rough and finishing cutting processes into a single process for rough and finishing. - Reduced the construction period from 7 days (rough processing + transportation + heat treatment + transportation + finishing cutting) to 1 day (rough and finishing cutting). *For more details, please visit our website or feel free to contact us.

Here is an example of achieving cost reduction through the size increase of tools. Since the width of the area to be machined with the end mill is a minimum of 5.742mm, end mills larger than Φ6 cannot be used. By changing the corner radius size from R1 to R2, the minimum width dimension expands to 6.086mm, allowing for machining with a Φ6 end mill, which leads to a reduction in processing time. [Case Summary] ■Issue: The width of the area to be machined with the end mill is a minimum of 5.742mm, so end mills larger than Φ6 cannot be used. ■Result: By changing the corner radius size from R1 to R2, the minimum width dimension expands to 6.086mm, allowing for machining with a Φ6 end mill, which leads to a reduction in processing time. *For more details, please visit our website or feel free to contact us.
