南谷製作所 List of Products and Services

We will design and manufacture a measuring tool for internal diameter groove measurement at NANTANI Manufacturing Co., Ltd. Taking into account the R of the internal groove and the corner R of the groove bottom, we will ensure that the straight surface of the groove bottom can be accurately captured. By setting it in our multipurpose caliper, comparative measurements with the ring master will also become easier.

Many ball measuring probes are of the type that bond steel balls, but our company can manufacture them as a single machined piece. The compatible ball diameters range from φ0.2 to φ100. If you request a special diameter from a steel ball manufacturer, they will produce 1,000 to 10,000 pieces, which means using only 2 for the measuring probe is wasteful. Machining them may ultimately be cheaper and faster in terms of delivery. If you have any issues with ball measuring probes, please feel free to contact us.

Many companies may have the problem of not knowing what to discuss or how to consult regarding measuring instruments. At Minamiya Manufacturing Co., Ltd., we offer proposals for multifunctional calipers (NMP calipers) tailored to customers facing issues such as "difficult measurements with general-purpose measuring tools," "errors caused by the measurer," "inability to measure due to interference with obstacles," "the need to measure groove bottom diameters or special parts," and "high measurement labor costs." The NMP caliper enables stable and accurate dimension measurement (comparative measurement) for various inner and outer diameters, and we propose specialized measuring tools for various measurements, including effective diameters of even and odd gears, large and small diameters, and inner and outer diameters of grooves. Due to its high durability and lightweight design, it is also suitable for measurements within equipment and for mass inspection of identical parts on production lines. 【Features】 ■ High measurement accuracy ■ Lightweight and excellent operability ■ Over 7,000 units sold cumulatively ■ Reasonable pricing ■ Numerous delivery records in the automotive industry ■ Adoption as standard products by major clients. *For more details, please download the PDF document or contact us mentioning "Ipros."

Our company manufactures involute spline through gauges and stop gauges. Based on high-precision wire cutting and actual measurements using three-dimensional measuring machines, we achieve higher precision machining by accumulating results in test machining, measurement, correction, main machining, and inspection. Supported dimensions: Spline parts up to 30 in length with straight shapes. For detailed accuracy specifications, please contact us. Thank you very much.

Measuring the over-pin diameter of internal gears and internal splines, as well as measuring the ball spacing such as between-pin diameter measurements, will become easy for anyone to do. - Zero adjustment with a ball (sphere) measuring device on the master - Measure the product - Confirm the measurement values by comparing with the master Please check the introduction video on YouTube.

• Transmission parts

Problems with inner diameter measurement: - Measuring the inner diameter of internal grooves like snap ring grooves - Inner diameter of small holes with a diameter of 20 mm or less - Unable to measure due to interference from the central shaft - Difficulty measuring with commercially available products - Measurement takes a long time - Measurement values vary depending on the person We will solve these issues.

• Transmission parts

Problems with external diameter measurement: - Measuring the outer diameter of external grooves like snap ring grooves - Measuring the outer diameter inside grooves carved on the end face - The measurement area is too narrow to access - The central shaft obstructs measurement - Difficulties in measuring with commercially available products - Measurement takes too much time - Measurement values vary depending on the person We will solve these issues.

We will measure the BCD of the ball screw shaft using three pins. While two-point measurements with a ball depend on the skill of the measurer, three-pin measurements allow anyone to easily achieve high-precision measurements. We will measure the BCD of the ball screw nut using three points. Although two-point measurements with a ball depend on the skill of the measurer, three-point measurements have less variation between operators compared to two-point measurements and can be performed easily.

There is a growing demand for small diameter spherical measuring probes for measuring extremely small gears. Our company manufactures integrated machined spherical measuring probes. The available diameters range from φ0.2 to φ150. The manufacturing tolerance depends on the diameter, but we can accommodate tolerances of ±0.001. Since they are produced through integrated machining, we can manufacture from a single piece. We can also accommodate special shapes, such as tip cuts for spline root interference relief. Materials available include SKS3, SKH materials, carbide, and coatings. We can produce spherical diameters not listed in catalogs, such as those for Mitutoyo ball micrometers, starting from one piece. Please feel free to contact us.
