About SNK technologyAbout SNK technology

Number of technologies which have been developed with customers

"We want to make a product which has not been developed in this world "SNK has challenged unflinchingly to realize the customers' thoughts.We believe that letting all customers use our product with satisfaction will connect to welfare of society…These thoughts have been came to fruition by large-sized machine tools such as double column type machine.SNK has established a position as leading large-sized machine tools builder.To generate many items with better quality by machine tools, SNK puts only-one and number-one technology into their products.In various point of view, we would like you to feel SNK's manufacturing EYE。

速 正 易 剛

剛

Strong and rigid machine required for large-sized machine tools. Sources, which generates powerful machining, are put in our products。

FEM解析

FEM analysis

Components are divided into multiple finite elements and numerical analysis is done. After that, high-rigid and optimal components are produced。

大径ボールスクリュー

Large diameter ballscrew

It enables the stable operation of large sized components. In cutting, it enables powerful cutting with high movement accuracy。

ダブルピニオン構造

Double pinion mechanism

By adding appropriate preload to pinion gear, high-rigid drive without backlash is configured。

高出力・高トルク主軸

High power & high torque spindle

With the spindle mechanism that withstands heavy cutting and two times high power and high torque specification compared with our conventional products, it achieves the largest chip discharge amount in the machine class。

正

Achieve micron accuracy by a machine with size of dozens of meters. We have been challenging accuracy that is essence for machine tools。

熱対称設計

Symmetrical heat distribution design

遠心鋳鋼管を門型コラムに採用することで、熱変位によるコラムの伸びを一定方向に定め、立て姿勢の精度管理が容易になります。

熱変位補正

Thermal displacement compensation

This function controls the machine to follow displacement that is generated by temperature change in the environment with large temperature fluctuation。

レーザー測定

Laser measurement

Various measurements are done automatically by non-contact laser。

DCS(Dynamic Control System)

DCS(Dynamic Control System)

DCS is the machining software that realizes high-quality surface finishing for curved surface of die and mold. It educes machine capability and pursues high productivity maximally。

速

Needs for high productivity which is requested from on-site of manufacturing. We pursue perpetually high-speediness that directly link with the needs。

軸芯冷却機構

Core axial cooling mechanism

Cooling oil is flowed inside of ballscrew that drives each axis to prevent ballscrew from extending by thermal displacement. It realizes high accuracy and long life of ballscrew。

リニアモータ仕様

Linear motor specification

In order to achieve high speed, high acceleration and high precision, we use linear motors for feed driving.

ツインモータ駆動

Twin-motor drive

By high synchronous control such as crossrail up and down movement, it realizes the feeding mechanism that enables to move large size components in high speed。

DCS(Dynamic Control System)

DCS(Dynamic Control System)

DCS is the machining software that realizes high-quality surface finishing for curved surface of die and mold. It educes machine capability and pursues high productivity maximally。

特殊材料の使用(複合材、セラミックス…)

Use of special material (Composite,Ceramics…)

Weight of components is reduced by using various kinds of special materials in machine components. It improves responsive of movement。

重心駆動

Gravity center drive

It has good straightness in up-down movement and improves responsive by highly balanced drive。

易

The important things which SNK has produced with the customers so that the customers can feel pleasure for manufacturing。

インテリジェントPC

Intelligent PC

Intelligent accuracy management function. It contributes machining analysis and machine pre-maintenance by checking operation status and history files。

新5面加工ソフト

New five-face machining software

Machining support software that provides better usability to educe the capability of five-face machining center maximally。

各種ソフトウェア

Softwares

Various functions are prepared as machining support to meet with the customers' needs. They can be used for management, precaution, maintenance and IoT。
