    【Introduction of SC-100X2

    The biggest point of this machine development is the X-axis on the right spindle, and the challenge in this project was to add the X-axis to the right spindle, secure machining capability and develop the technologies to shorten the cycle time at the same time.

    Superimposed machining is a breakthrough technology that enables simultaneous cutting with one turret, and SC-100X2 can create a superimposed machining program just by selecting the process to be machined together.

    By using the lower turret, you can also machine left and right at the same time using two tools. The lower turret has also an unload gripper as standard, making possible to quickly unload the part when finished.

    【Comment from Senior Executive Director Shogo Nakamura】
    I imagine whoever engages in a machining work may have a desire to reduce the cycle time furthermore. However, I often hear opinions from customers that they are not able to add any more machining conditions, or they are not sure which command should be set and how to coordinate it to shrink the cycle time.
    From those opinions, we developed the Program Optimizer Function. Once users select an item, the optimization will be set instantly without any complex settings.
    We already have a case succeeded in 11% reduction of cycle time. I am grateful if this newly embedded function can contribute to our customer to succeed in the reduction of more cycle time.

    【What is oscillating cutting?】
    Oscillating cutting is a cutting method to oscillate the tool in the cutting direction by servo control and cut chips into small pieces. The oscillation of the tool creates air-cut area, which cut chips into pieces.

    This image has an empty alt attribute; its file name is 揺動英語.png

    【Background】
    The oscillating cutting function was originally a technology that was mainly used on automatic machines. For this reason, its use on large machines with a maximum diameter of 600 mm or more, such as the NTRX-300L, is an advanced example in the world.
    Both large and small machines are subject to the same problems of chip roll. Especially on machines with ATC, tool changes with chips wrapped around the tool are more likely to lead to downtime, e.g. alarm stops.
    This is why we have repeatedly experimented with machines that are designed to be automated for longer periods of time.
    Actual machining tests have been carried out to verify the risks involved, including the risk of reduced component life. The results showed that the risks were lower than expected and that they could be reduced by adjusting the conditions.
    This led to the expansion of the number of models equipped with this technology.

    【Advantages of oscillating cutting】
    The use of oscillating cutting prevents the chips from tangling around the tool and workpiece and improving the chip-flow. This reduces the number of scrapped parts and reduce machine downtime, which leads to higher productivity.
    Another attractive feature of the oscillating cutting function is that it is easy to program by using just a G code command.

  • 【Press Release】Automation of jaw change by “Flex Arm”

    
    
    
    
    Nakamura-Tome Precision Industry (Hakusan City, Ishikawa Prefecture, President: Kenichi Nakamura) has developed a new product, “Flex Arm”, which enables complete automation from workpiece transfer to jaw replacement. By incorporating the Flex Arm, the entire process from workpiece transfer to jaw replacement can be fully automated. It allows for automated operation for multiple types of workpieces without stopping the machine.
    
    
    
    
    
    

    【What is Flex Arm?】
    Flex Arm is a new product that completely automates everything from workpiece transfer to jaw replacement.
    In addition to the loading of materials and unloading of finished products by the conventional compact loader, the new Flex Arm has an additional hand change and chuck jaw change function.
    This enables unattended automatic operation for multiple types of workpieces without stopping the machine.
    Another attractive feature is that the height of the machine is the same as that of conventional machines, making it a space-saving machine.

    【Advantages of Flex Arm】
    The key to unmanned nighttime operation in a high-mix, low-volume production is change of the types of products.
    In the past, automation has mainly focused on loading materials and unloading finished products.
    At this time, automation for the product changeover has been one of the biggest challenges.
    By using Flex Arm, unmanned nighttime operation with product changeover is possible, which is expected to improve production efficiency.
    In addition, the Flex Arm system is mounted on the machine and can be easily controlled by the operation panel attached to the machine, compared to changing jaws with an industrial robot.
    Also, since the system is installed in the machine, it is highly compatible with the machine, and the start-up time is fast enough to be used immediately after delivery.

    【Developer’s voice】
    In recent years, with the shift to high-mix low-volume production, we have received many requests from customers who want to automate setup changes.
    Some customers have said, “We can’t secure enough human resources for the night shift to change the jaws and change the product type,” and others have said, “Even if we wanted to automate the process for a single product, we can’t because there are not enough number of workpieces.
    We have been developing Flex Arm to solve these customer needs and to realize long-time automation in a high-mix low-volume production environment.
    We hope that Flex Arm will solve the problems of troublesome and time-consuming setup changes and make our customers happy.

    【Transport workpiece size】
    Diameter range : 32mm to 100mm
    Length : 50mm to 100mm
    Weight : 3kg
    ※As of July 2021, WY-150 will be available for installation.
    We are gradually expanding the number of models equipped with this function.

  • Chatter Canceller is Standard Equipment on 30 Models.

    Nakamura-tome Precision Industry Co., Ltd. is pleased to announce the addition of the “Chatter Canceller” function to 30 of its products as a standard feature.
    By incorporating the Chatter Canceller function, chattering can be suppressed without significantly reducing machining conditions, and in addition, surface roughness can be prevented from deteriorating, and tool life can be reduced and damage can be prevented.

    The effect of Chatter Canceller

    【Background】
    We have received many concerns from our customers regarding chattering during machining. In the cutting process, chattering causes deterioration of surface roughness, reduction of tool life, and damage, and we have been looking for a solution to this problem.
    This time, we approached the chattering phenomenon from a different perspective, and as a result of repeated in-house experiments, we were able to confirm the effectiveness of chatter suppression, which led us to incorporate the function into 30 models.

    【What is Chatter Canceller?】
    Chatter Canceller is a function that suppresses the occurrence of chatter by periodically changing the spindle rotation. (*1)
    Normally, when chattering occurs, measures are taken to suppress chatter by reducing the machining conditions, but Chatter Canceller has less impact on the machining time than measures to reduce the machining conditions.
    Chatter control can be commanded by adding two lines of M code, minimizing the burden on the operator.

    Suppresses chattering by varying the spindle speed.

    【Developer’s voice】
    We believe that chattering is a great enemy for those who are engaged in machining. The good thing about this function is that it can be easily executed by anyone with only two lines of M-code, so we would be very happy if our customers could use it and feel the effect. We have conducted many experiments in our company, so if you have any problems, please contact us first.

    【Consultation with Nakamura-Tome】
    Nakamura-Tome accepts inquiries from customers. Not only do we accept inquiries about vibration care, we also accept inquiries about products and processing.
