HIKOYAMA SEIKI CO.,LTD. Product Lineup

Our company conducts research and development using Additive Manufacturing. This manufacturing method has a low heat input, resulting in minimal impact on the base material, and allows for easy thick build-up. Additionally, it can be used for applications such as restoring roll diameters and as a surface treatment alternative to hard chrome plating. 【Features】 ■ Low heat input, resulting in minimal impact on the base material ■ Easy thick build-up (approximately 300μm in one pass) *For more details, please download the PDF or feel free to contact us.

This document introduces an image of DED coating in research and development using Additive Manufacturing (layered manufacturing). The first layer of the dilution layer is an alloy of the coating (SUS316L) and the base material (S45C). The second layer of the dilution layer is the coating (SUS316L), and the third layer is also the coating (SUS316L). Furthermore, in the image of the first layer of DED coating, the penetration depth is approximately 0.3mm, and the melt pool depth is about 1mm. *For more details, please download the PDF or feel free to contact us.*

• Contract manufacturing

Our company offers "laser processing." We own a Yamazaki Mazak INTEGREX e500H, which allows for welding that is not possible with conventional welding, such as overlapping joint welding. Additionally, we also provide hole drilling processing over plating using a laser drill. 【Features】 ■ Welding that is not possible with conventional methods ■ Hole drilling processing over plating *For more details, please download the PDF or feel free to contact us.

We would like to introduce our "Roll Repair" services. We restore precision that has deteriorated over time due to scratches, dents, and wear. With our in-house equipment for consistent production, we can respond quickly. Additionally, we can also handle some processing such as "primary processing of pipes" and "cylindrical, inner surface, and flat grinding," so please feel free to consult us when needed. [Features] ■ Improvement of roll defects ■ Performance enhancement ■ Contracting for partial processing *For more details, please refer to the PDF document or feel free to contact us.

• Calibration and repair

We would like to introduce the "fine groove rolls" that we handle. We also perform various processing methods such as single and multiple cutting, cross-cutting, and lateral drawing, and we can accommodate fine processing beyond optical systems. Additionally, we check for chipping or wear on the processing tools and confirm the replicas after processing using a laser microscope. During processing, we also observe for any abnormalities using a CCD camera. 【Features】 ■ Diverse know-how in fine processing ■ Various pattern processing ■ Fine processing on large rolls *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our "Metal Layered Surface Treatment" that we offer. In the past, it was difficult to repair rolls when the outer diameter of the body became extremely small due to wear. However, with layering, it is possible to build up the surface by several millimeters, allowing for regeneration of rolls in any condition. Additionally, by using our surface treatment technology, we can manufacture the core from inexpensive materials and apply high-performance metals only to the surfaces that come into contact with chemicals, leading to significant reductions in material costs. 【Features】 ■ Alternative to hard chrome plating ■ Restoration of existing products is possible ■ Conversion of inexpensive materials into high-performance materials *For more details, please refer to the PDF document or feel free to contact us.

We handle "press rolls" made from high-hardness materials. By using materials such as SKD11 vacuum-hardened products, we enable high hardness in our products, achieving longer lifespan for the rolls. Our expertise is applied not only in processing but also in the selection of tools and grinding wheels. Additionally, due to their large diameter and heavy weight, achieving precision can be challenging; however, we have a proven track record of producing press rolls with a diameter of φ750 to an accuracy of 1μm. 【Features】 ■ Use of high-hardness materials ■ Single unit runout accuracy of 1μm *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce the "Large/Long Rolls" that we handle. We have five large NC lathes capable of processing over φ1000, with the maximum processing size reaching φ2200. Additionally, we have four NC lathes with a center distance of 8m to 14m, establishing a mass production system for long rolls. 【Features】 ■ Capable of processing up to φ2200 ■ Capable of processing lengths up to 14000mm ■ Achieves good balance *For more details, please refer to the PDF document or feel free to contact us.

We would like to introduce our "Coating Roll" that we handle. The selection of materials, as well as the addition of heat treatment during intermediate processes such as roughing, is carried out through suitable processes to maximize the characteristics of the materials. In addition, to achieve a runout accuracy of 1μm after assembly, we pay close attention not only to the rolls but also to the bearings and housings. 【Features】 ■ Processing that utilizes the material ■ Stable supply of bearing unit runout accuracy of 1μm after assembly ■ Production of a wide variety of coating rolls *For more details, please refer to the PDF document or feel free to contact us.

We handle "suction rolls" made with nickel mesh. We can manufacture variable width and heated types, and we offer comprehensive after-sales support. It is also possible to produce an exact replica of a roll that is already in use, even without a drawing. Additionally, we offer coating rolls, metal laminated surface treatments, fine groove rolls, press rolls, and large/long rolls, so please feel free to contact us with your requests. 【Features】 ■ Made with nickel mesh ■ Capable of manufacturing variable width/heated suction rolls ■ Comprehensive after-sales support ■ Proposals based on extensive knowledge *For more details, please download the PDF or feel free to contact us.
