We have compiled a list of inquiries we frequently receive.
We welcome questions other than those listed below, so please feel free to contact us.
About Machined Parts Manufacturing
- What kinds of materials can you machine?
- We primarily machine **steel, stainless steel, and aluminum**.
We also have experience machining difficult-to-cut materials such as **quenched steel, Inconel, and titanium**. - Can you machine resins?
- We have experience in machining complex shapes in **resins**.
- Can you deliver finished components (including heat treatment, welding, grinding, plating, etc.)?
- Yes, it is possible. We have a network of over 50 companies called the Yamamoto Kinzoku Kyowakai,
allowing us to handle a wide range of processing, including **grinding, heat treatment, plating, welding, and sheet metal processing**. - What level of precision can you achieve? (e.g., how many microns)
- We can achieve precision up to **±0.005mm**. We also handle test pieces that require high precision.
For precision finer than this, please consult with us separately. - What is the maximum size you can machine?
- We can handle sizes from **φ5 to φ700**.
- Can I place an order for just one piece?
- Yes, we can handle orders starting from **one piece**.
- Can you handle quantities of tens of thousands of pieces or more?
- This can be handled by our group company, **Yamamoto Precision**.
- What is the turnaround time (delivery time)?
- The delivery time varies depending on the drawing, machine availability, and complexity of the request,
so we handle it on a case-by-case basis. - Can I know the price beforehand?
- We will provide a quote and delivery time after inquiring about the machining shape, material, required delivery time, and quantity.
- Do I need to bring in the materials myself?
- We will procure the materials based on the drawings provided.
However, there may be cases where special materials cannot be sourced. - Can you perform a 100% dimensional inspection?
- Yes, we can if you request it at the time of the machining order.
We can also provide the measurement results if necessary. - How many machine tools do you own?
- We own **145 NC lathes**, **17 machining centers (vertical, horizontal, 5-axis)**, and multiple cylindrical grinding machines, etc. Please see the [Equipment List](/company/equipment) for details.
- What kind of measuring equipment do you own?
- We have a quality assurance system equipped with many inspection devices, including **3D Coordinate Measuring Machines**.
We also support non-destructive testing such as **PT, UT, and MT**.
Please see the [Equipment List](/company/equipment) for details. - Is it possible to request only dimensional measurement for urgent products?
- We also accept requests for measurement only.
We can flexibly arrange staff to meet short-notice requirements.
Please see the [Measurement Services](/company/equipment) for details.
About Equipment and Machinery
- I am interested in a cutting force dynamometer; is it possible to purchase one from your company?
- We have a business alliance with Kistler Japan and are also an **authorized dealer for Kistler products**. If you are interested, please feel free to contact us.
- Is it possible to handle fixtures and equipment for site improvement,
from design to assembly (device)? - We also accept the manufacture of **custom-made equipment**.
We have experience ranging from a single fixture to automated line devices.
Please see our [Product Information](/products) for details.
If you have any issues, please contact us.
About Measurement and Evaluation Equipment
- Is it possible to request only a fatigue test?
- Yes, it is possible as we are also a **contract testing facility**.
We also accept requests starting from the production of test pieces.
Please see the [Material Testing Service](/service/lab-test) page for details. - Is it possible to request both the production of a rotating bending fatigue test piece and the test itself?
- Yes, we can handle it starting from the test piece production, as we have many years of accumulated know-how in cutting and machining.
Please see the [Material Testing Service](/service/lab-test) page for details. - For expensive materials like 3D printer materials, I cannot provide a large parent material. Is fatigue testing still possible?
- There is no problem if a test piece with a minimum diameter of **φ5** can be produced.
We also have experience in evaluating **3D printed (metal additive manufactured) materials**.
Please see the [Metal Additive Manufacturing Material Evaluation Test Service](/service/am-test) page for details. - What are the key features of the GIGA QUAD®?
- The biggest feature of our testing machine is that it is a **4-station type**, which allows for quick data collection and efficient creation of **S-N curves**.
Furthermore, it is possible to conduct fatigue tests simulating high loads and actual environments.
Please see the [GIGA QUAD®](/products/gigaquad) page for details. - Is it possible to try out the MULTI INTELLIGENCE®?
- The MULTI INTELLIGENCE® (both Cutting and FSW types) is available through our **rental service**. Please use it for optimizing machining conditions on your company’s actual machine.
Please see the [MULTI INTELLIGENCE®](/products/m-intel) page for details.
About Evaluation Test Services
- Can I get a report of the test results for the Machinability Evaluation Test Service?
- Yes, it is possible if requested during the initial meeting.
We can also provide the data collected during the test. - I am considering requesting the Machinability Evaluation Test Service; can you also propose a testing plan?
- Yes, we can select the testing conditions (machine, tool, cutting conditions, etc.) and create a specification document for you.
However, a separate meeting will be required for this purpose. - Is it possible to be present during the Machinability Evaluation Test?
- Yes, it is possible. The Machinability Evaluation Test Service is primarily conducted at our **Okayama R&D Center**, so you would need to visit this location.
- Is it possible to be present during the FSW Evaluation Test?
- Yes, it is possible.
The FSW Evaluation Test Service is primarily conducted at **YAMAMOTO Lab (within Toyama Industrial Technology Research and Development Center)**, so you would need to visit YAMAMOTO Lab. - Is it possible to have a meeting about the testing other than by phone or email?
- Yes, meetings are possible using a **WEB conferencing system**.
We can accommodate you during business hours (9:00 – 17:00), so please feel free to request it.
