All parts related to quality are precision machined to keep a 0.02 allowance.

• About 40% of part are precision machined. (Single reduction - Adapter type)
• There is no exception for this rule, including even the smallest parts, such as pins and bushings.

We use the right materials.

• We use high-carbon chromium alloy steel (SUJ2 bearing steel) for core reduction parts.
• Materials for core parts are heat-treated to acquire the right material properties.
• High quality bearings are used for input parts directly connected to the high-speed motor

We continuously invest in core technologies to improve our quality level.

• We internalized cycloidal gear design technology the keep upgrading the design.
• We research various technologies te reduce noise/vibration and to increase effciency.

We do NOT compromise on quality standards to reduce cost.

• We do NOT use refurbished or used parts for which we cannot guarantee quality.
• We do NOT accept any expedient design changes the undermine quality standards.

With a high efficient mass production line designed only for cycloidal gear reducers, We have achieved both short lead times and low production costs.

• We have about 45 machine facilities, including automated production facilities.
• We have 22 remodeled machines only the cyloidal gear reducer manufacturing.
• Most of our field workers have more than five years of experience at HDM

The entire production process is effectively managed with an innovative production management system.

• From order to delivery, 2,100 manufactured parts are tracked and managed with one integrated system
• Thus we can maximize production efficiency, resulting in short lead time and low production cost
