HAKUSAN, ISHIKAWA―Nakamura-Tome Precision Industry Co., Ltd. (CEO Shogo NAKAMURA) is delighted to announce the full-scale operation of our new assembly plant, “MAGI,” which was completed in July last year. With this milestone, we have introduced a new production system designed to reduce worker burden, improve production efficiency, and shorten machine lead times. 

YouTube
https://youtu.be/WpqWnRtftuw

Introduction of Automated Guided Vehicles (AGVs) 
As part of our new production system, we have integrated Automated Guided Vehicles (AGVs) into our factory operations, specifically for assembling index units and slides. The AGVs autonomously transport the necessary units for assembly, eliminating the need for dedicated transport workers and freeing assembly workers from the task of fetching parts. This advancement has successfully reduced the monthly man-hours spent on transport by an impressive 480 hours.

Once assembly is complete, the AGVs automatically transfer the units to the stacker. With four pallets set up in each area and the next work parts pre-delivered, we ensure no waiting time, enabling seamless and efficient assembly work. This stacker system has dramatically reduced the lead time, for some model from 25 days to 15 days.

In-House Developed Delivery Management Software
To complement our AGV integration, we have developed proprietary software to manage the status, priorities, and assembly schedules of each unit. This software facilitates inventory checks, ensuring that workers are always engaged in high-priority tasks.

By automating and systematizing the flow of delivery, assembly, and shipping or storage of goods, we create an environment where workers can focus more on their core tasks. In the future, we aim to continuously improve quality and efficiency in assembling not only index and slide units but also spindle and tool spindle units, ultimately delivering products to our customers faster and more efficiently.

HAKUSAN, ISHIKAWA—Nakamura-Tome Precision Industry Co., Ltd. (CEO Shogo NAKAMURA) has announced a newly developed chip-breaking function, “Triangle Cut.” The Triangle Cut can be applied to all slide-guided machines, including box-way machines that cannot utilize the Oscillating Cutting function*1. With this announcement, it is now possible to install a chip-breaking function in all of Nakamura’s model lineup.

*1 Please refer to the following link regarding the Oscillation Cutting.
https://www.nakamura-tome.com/oscillation_cutting/

■What is the Triangle Cut?
It is an optional function that processes while breaking chips by operating the turning path in a triangular shape. Drawing a triangular path moves the cutting edge away from the workpiece, and the chips are divided due to air cutting.

■YouTube
https://youtu.be/e86LmnMBP5s

■How to use the Triangle Cut?
The Triangle Cut can be applied to a concerned machining program section by enclosing it with dedicated G codes of G338 (start code) and G339 (end code).

G338 A__. B__. [C__.] D__. …Turn on the Triangle Cut
G01 Z-10. F0.2
X60.
X70. Z-15.
G339 …Turn off the Triangle Cut

A：Finish allowance (A+C = the height of the triangle)
B：Spindle rotation speed until completion of triangle hypotenuse (two hypotenuses) operation
C：Clearance amount
D：Machining direction

■Advantages and Disadvantages
Compared to the Oscillation Cutting, the Triangle Cut tends to reduce the deterioration of surface roughness and can be suppressed to 1.2 to 2 times the level of normal turning. On the other hand, the machining time could be 2.7 to 3 times longer due to the extension of the processing path.

*2 Comparison in the finishing process
*3 Only the X/Z axis of the linear-guided machines can be applied.

■Development background
The cutting chip problem is unavoidable for production sites, and the burden on the production site caused by this problem is also heavy. With the evolution of machinery and servo technology, the Oscillating Cutting function has been put into practical use, and its programming can easily solve chip problems. However, the Oscillation Cutting is difficult to apply to box-way machines because they are at risk of damage due to the high-speed movement of the Oscillation Cutting.

We have received numerous inquiries regarding the application of Oscillation Cutting to box-way machines. To address this issue, we searched for a way to divide the chips reliably and developed the Triangle Cut.
Instead of using a special program, we have devised a way to perform chip-breaking operations by adding simple G-code modifications to the processing program already in use.
We hope you will use it as a function to solve the chip problem in the field.
