Recently, the leaders of Xi'an Changdao Precision Industry, along with their technical team, went to Changdao Precision Industry in Japan for an in-depth exchange project, to inspect and learn about ultra precision grinding equipment (thread grinding) and specialized grinding equipment for cutting tools and other grinding machines.

01 μ m machining accuracy

There are two models of Long Island Precision Small Internal and External Thread Grinding Machines.

Changdao Precision Small Internal and External Thread Grinding Machine

The main use of external thread grinding "TO10-30" is for mold parts, screw gauges, ball screws (planetary roller screws), etc;

Internal thread grinding "TI10-10" is specially designed for processing thread gauges, precision nuts, and other products.

02 Easy to operate

The thread grinding software independently developed by Changdao Thread Grinding Machine only requires inputting the required thread specifications and shapes for editing, and can perform thread grinding according to the thread processing parameter program set by the editor.

No need for complex program calculations or machine adjustments, it can process all products from standard screws, irregular screws to ball screws (roller screws).

The machining correction function is also very powerful, which can correct the lead and effective diameter of the screw within any machining range.

Standard manual interlock function for easy alignment of workpieces and grinding wheels

Manual interlocking function

The grinder is equipped with a roller dresser that can install Form disc rollers. According to the required thread requirements, different thread shapes and contours of the grinding wheel can be formed and trimmed for grinding processing.
