By 2030, the global robotics market size is expected to range anywhere from $160 billion to $260 billion. The world is expecting robots to do a lot of the “heavy lifting” going forward. But with demand pressuring supply for many of the essential components, new production technologies are needed to keep pace. Nowhere is this truer than for the smaller, high-precision spiral and hypoid bevel gears that play such a critical role in transmitting power and delivering precise, reliable movement in increasingly complex, multiaxis robotic systems. Yet, manufacturers of these gears have, up until now, had surprisingly few options available to help them ramp up production of this new generation of high-efficiency bevel gears—particularly in the increasingly common size range of 100 mm in diameter and smaller. 

This article by Reishauer AG summarizes the insights gained from digitization in the machine tool sector, highlighting the long-term collaboration between the two companies. ZF Getriebe Brandenburg GmbH, distinguished by a team of over 1,500 specialists, leads in producing exclusive manual and dual-clutch passenger car transmissions used in high-end German sports cars for maximum precision and performance. A crucial factor in the quality of these transmissions is the precise ground gears manufactured on machines from Reishauer AG, a Swiss pioneer in gear grinding machines. 

For more than 60 years, Forest City Gear has crafted a legacy of excellence in precision gear manufacturing, leveraging advanced techniques and cutting-edge technology to earn the business of customers as exclusive as NASA. At the heart of the company’s technology-focused philosophy lies a long-time relationship with Sunnen Products Company, a leading manufacturer of honing systems, tooling, and accessories. The relationship helped Forest City set itself apart as one of the world’s most precise gear makers, and now the company’s parts are found on everything from fishing reels to the Mars Rovers.

The importance of clean air in manufacturing is often underestimated, yet it’s one of the critical elements that can impact both production efficiency and employee well-being. This is particularly true in facilities that rely heavily on CNC machining, where oil mist and coolant byproducts can create significant air quality challenges. Wolfram Manufacturing, based in Austin, has addressed this challenge head-on by integrating advanced mist collection systems into its operations.

As the automotive industry continues to move towards e-mobility, the manufacturing world is adapting to the respective requirements. Large gear ratios are necessary to reduce the high input speeds of electric motors to the required speed of the drive wheels. At the same time, masking noise of combustion engines is now missing, posing challenges to the noise level of transmissions. Principally, two main transmission concepts have become established for e-drive applications: two-stage layshaft transmissions with four gears, and planetary transmissions.

If all goes as planned, NASA will launch its Sample Retrieval Lander (SRL) Mars mission from Florida’s Space Coast in June 2028, the start of its latest, and greatest, mission to Mars. By sometime in the early 2030s, the SRL mission will have succeeded in traveling to Mars; gathering samples already collected by the Perseverance Rover; launching them into Mars orbit; and capturing and returning them safely to Earth. For NASA’s scientists, the SRL mission is the culmination of a decades-long series of Mars explorations designed to find evidence of life outside of Earth or, at the very least, provide important insights into the origin of life here on Earth.

The International Manufacturing Technology Show (IMTS)—September 9–14 at Chicago’s McCormick Place—is the largest manufacturing technology show and marketplace in the Western Hemisphere, and it’s right around the corner! With visitors from more than 110 countries, IMTS is where the creators, builders, sellers and drivers of manufacturing technology come to connect and be inspired. But with more than 1.2 million square feet of exhibit space, where do you begin? Here at Gear Technology, we do our best to help you make the most of your show experience by assembling booth previews that will be worthy of your attention.

The 67,000 sq. ft. facility occupied by Precision Gears Inc. in Pewaukee, WI, contains a full range of gear manufacturing equipment to meet the varied customer demands of the many industries it serves. Founded in 1919, the company possesses both the technologies and experience to efficiently serve the multiple requirements of manufacturers in fields as varied as agriculture, lawn and garden, foodservice, power transmission construction, pumps, and others.

Gears serve as essential mechanisms in a wide range of mechanical equipment, helping to transmit torque, adjust rotational speeds, transfer power, distribute load and more. Used in necessary applications such as automobiles, energy systems, aerospace and industrial equipment, gears must be able to operate for long periods without maintenance. While gears can be made from a diverse assortment of materials, carbon and alloy steel offer superior benefits in terms of strength, durability and cost efficiency. As a remarkably recyclable material, steel may also be a preferable choice for environmentally conscious manufacturers.

This article requires that the reader be familiar with Job Shop Lean, an approach to adapt the principles of lean manufacturing for a job shop, regardless of its size or industry sector. A job shop typically executes a different schedule every day. Each day’s schedule could have a different mix of jobs, due dates, lot sizes, and number of gear operations. Regardless of all these differences, it is important that the shop receives a feasible schedule that does not exceed available capacity constraints on key resources (machines, labor, materials, dies, etc.).
