生産能力の増強と高精度製品を目指し、数値制御式管板穴明専用機NC1号機を導入

大阪市平野区に新工場を建設し移転（510㎡で空調装置付）

数値制御式管板穴明専用機NC2号機を導入

厚板の管板穴明に対し、深穴明専用機（BTB&GANDORILL併用）及び邪魔板の自動面取機を導入

小型管板（Φ800以下）の穴明専用機（NC）を導入し、従来の罫書作業をNC化

厚板の管板２枚が同時に穴明出来る様、深穴明専用機（BTA）2号機を導入し、穴明期間を短縮化

穴明の完全自動化を目指しNC穴明専用機（FMC-20/25VP)を１台導入

関連会社、株式会社協和エンジニアリングを設立し、輸出入部門の強化を図る

第2工場を設立し、完全自動化を目指すと共に、大型製品の対応を図るべく大型NC機を４台導入

大型穴明工場を目指し、三井造船（株）構内に大分工場として移転。超大型管板穴明に対応すべく大型NC機を１台導入

本社を大阪より大分市に変更移行

生産能力を拡大する為、三井造船（株）大分事業所隣接地を購入し新工場及び事務所建設。同時に『株式会社KYOWA』に変更登記。既に1台設備していた超大型NC機を更に改良した超大型NC機を２台導入し大型化に対応

A棟西側に増築（960㎡）建屋を延長（30ｍ）して現在所有している大型ＮＣ機３台よりも２倍の能力を持つ超大型ＮＣ機（４軸）を１台導入

管板穴明に関して効率の良い横形（クエリタイプ）マシニングセンター（NC機・寸法3000×3000）全面切削油飛散防止カバー付を２台同時に導入

A棟西側工場建屋を２０ｍ延長して工場全体で6925㎡の全長最大140ｍの穴明け機械工場にする

２年前に導入した横型マシニングセンターの大型化し改良を加えたNC機を１台導入し全面切削油飛散防止カバー自動開閉付き）天井クレーン（トロリ式）75ｔ＋20ｔの親子タイプを１基導入

汎用ターニングでは受注が手薄の為、電子制御付き（NC）ターニングを１台導入し加工範囲を4000ミリまで大型化対応する。

Established the kyowa factory in Osaka City is Ikuno Ward.

Moved factory to Osaka City’s Hirano Ward and establishment of Kyowa Co.,Ltd.

Increase of production capacity and high precision products, introduction of numerically controlled tube sheet drilling specific NC2 machine

Move to newly built factory in Osaka City’s Hirano Ward(510㎡air conditioner)

Introduction of numerically controlled tube sheet drilling specific NC2 machine.

Introduction of the deep drill machine(BTB&GANDORILL dual use) for thick tube sheet plates and automated chamfering machine for baffle plate.

Introduction of drilling machine (MC)specific for small-scale tube sheet (below ΦU800)and all marker-gauge are NC.

Able to drill 2 sheets of thick tube sheets, introduction of second deep drilling machine (BTA), shortening of drilling time.

Introduction of NC drilling machine(FMC-20/25VP)for full drilling automation.

Kyowa Engineering Co.,Ltd, sffiliated company is establishe, strengthening of export department.

Establishment of second factory,strive toward full automation and introduction of 4 NC machines for large-scale products.

Strive for large-scale drilling factory,move to Oita factory premises of Mitsui Engineering & Shipbuilding Co.,Ltd. Introduction of large-scale NC machine for super-sized tube sheet drilling.

Branch office strengthening by moving headquarters operations to Oita factory.

To broaden production capacity, land was purchased from Mitsui Engineering & Shipping Co.,Ltd. Building of new factory and changed company name to “KYOWA Co., Ltd” at the same time. Improvement of previous super-sized tube sheet drilling machine ane introduction of a further 2 super-sized tube sheets drilling NC machines.

Introduces supersized NC airplane I do extension (30m)of enlargement(960㎡), and to have ability double than three large-scale NC machines owning now (four axes)into the A ridge west

Introduce a pipe board about making hole at two same time with prevention of efficient wide form (query type)machining center(NC dimensions 3000×3000) entire surface cutting oil scattering cover

Extend A ridge west factory 20m and make it the perforator machine shop of full length maximum 140m of 6,925 square meters in the whole factory

Introduce one NC machine that I upsize , and increased improvement of the wide form machining center which I introduced two years ago(with the prevention of full-scale cutting oil scattering cover automatic opening and shutting)and introduce one parent and child type of overhead crance(torori)75t+20

Because an order is insufficient by the general-purpose turning;with the electronic control introduce one turning(NC),and support upsizing,and do a processing range to 4,000 millimeters
