Multitasking Machines Perform Gear Work, Traditional Machining
Gear Expo 2017: Mazak will demonstrate its multitasking equipped with the latest Mazatrol Smooth CNC and Mazak Smooth Gear Cutting Solutions for making precision gears of all shapes and sizes.
Mazak Corp. will demonstrate its multitasking equipped with the latest Mazatrol Smooth CNC and Mazak Smooth Gear Cutting Solutions for making precision gears of all shapes and sizes. More than 90 model configurations of Mazak’s multitasking machines can be paired with software and CAD/CAM systems to perform a variety of operations in a single setup, including hobbing, forming, surfacing and skiving. The machines are ideal for shops with occasional gear work because they can be used to turn a part’s internal and outer diameters, process its mating features and power-skive its gear tooth pattern, as well as process a range of non-gear components. The ability to process so many features on one machine is said to improve overall accuracy, because each part feature runs true to the gear teeth.
The Mazatrol SmoothX CNC is said to operate four times faster than the company’s previous-generation controls. It is designed to provide faster rotary axis speeds, enabling the machine tool to quickly perform gear hobbing and skiving operations.
The company will also highlight its closed-loop gear machining strategy designed to simplify the measurement and validation of gear tooth profiles.
Over the years, this Indiana job shop/contract manufacturer developed a specialty in gear making. Now it is taking this specialty to a grander scale. Two large machines for high-precision internal gear grinding are the main anchors of the company’s new precision grinding room.
Another type of tool engages comparatively more of the work to facilitate larger stepovers for improved efficiency and surface finish in five-axis finishing operations.
One core competency that has undergone major change is gear production. Current European law mandates more strict noise control. To meet regulations set forth, Harley-Davidson motorcycles were required to reduce noise output. Anticipating that this would soon become standard in other coun-tries as well, the company modified its transmission to include gear ratio changes and high contact tooth geometry.
