[Tool Regrinding・Desktop Processing Machine] Cutting Edge Positioning・Drive Motor
Explanation of the setup and automation of a tabletop drill sharpening machine. A stepping motor that can be considered for precise edge sharpening and positioning.
In metal processing factories, the use of "drill sharpening machines" that regrind used drills and end mills without discarding them, thereby extending tool life, is on the rise. These tabletop devices allow anyone to easily achieve accurate cutting edge angles and thinning grinding simply by "aligning visually," without relying on the skills of experienced workers, and they boast high demand as a definitive solution for reducing processing costs. In the design of such tabletop grinders and tool grinding devices, the precision of the "positioning mechanism," which finely controls the cutting edge position of the drill and the grinding approach angle, significantly affects the grinding quality (cutting edge strength and sharpness), in addition to the drive unit that rotates the grinding wheel uniformly at a constant speed. Our "stepping motor series" can be considered as a drive axis for these tabletop grinders and automatic tool regrinding devices, responsible for precise positioning of the grinding head angle adjustment and feed mechanism. They can be utilized as actuators that achieve high reproducibility in grinding precision while keeping costs down without using expensive servo motors.
basic information
■ Technical Key Points of Tabletop Drill Grinding Machines and Tool Processing - Reproducibility of Cutting Edge Angles: It is essential to achieve feed accuracy that allows for the setting and grinding of drill tip angles, relief angles, and thinning shapes with micron-level reproducibility. - Space-Saving Design for Tabletop Size: To enable installation next to workbenches or tool changers in factories, it is crucial to have compact drive components and a simple control structure. ■ Features of Stepper Motors for Grinding and Processing Equipment - Precise Pulse Positioning: Since angles and distances can be accurately controlled by the number of pulses, this can be utilized for fine feeding of the grinding head and for the positioning mechanism of the drill. - Overwhelming Cost Advantage: The design can incorporate open-loop control that does not require encoders, significantly reducing manufacturing costs for tabletop devices and prototype equipment. - We conduct domestic inspection for all units, from prototypes to small lots, before delivery.
