Difficult to process & difficult to cut [Case studies for solving problems]

The nut won't fit...

This is a case of a product for which we received a consultation stating, "The nut manufactured according to the drawing does not fit into the product." Despite the nut with an outer diameter of φ390 and an inner diameter of M340 being completed as per the drawing, it did not fit into the product, so we conducted an investigation at Sanri Special Steel. The dimensions were processed according to the drawing, but when measured with a three-dimensional measuring machine, distortion was found in the threaded portion of the inner diameter. Such phenomena can often occur with spacers, collars, sleeves, and various other products, not just this nut. Sanri Special Steel has produced many difficult-to-machine thin-walled ring-shaped products and supports customers with the know-how accumulated over many years. Detailed materials are introduced in our catalog, so please take a look. We offer a wide range of services including materials, heat treatment, turning, machining, polishing, and inspection. We will provide the best proposals for our customers. For all your manufacturing needs, please leave it to Sanri Special Steel Co., Ltd.!
