Precision fabrication can be: normal and high accuracy.

Pipe on the accuracy of production can be high and normal precision.

The inner wall of the bearing block is designed to be a regular polygon, so that structure precision of a manufacture die and manufacture precision are not so demanding.

Precision in the manufacture of these components is vital.

Installation requires an exacting amount of precision in fabrication.

Said method can easily remove fumes from a chamber and improves the fabrication precision and the irradiation-positioning precision of a light beam.

Pipe on the accuracy of production can be high and normal precision.

Therefore, the method for manufacturing a holographic blazed grating implements multi-parameter control of blazed grating manufacturing, so that the manufacturing precision is improved.

The decrease in the volume of the chamber (C) allows the fumes to be removed easily, and improves the fabrication precision and irradiation-positioning precision of the light beam (L).

Furthermore it needs only low manufacturing precision and low cost.

In this way, the manufacturing precision can be ensured and the production cost can be effectively conserved at the same time.

Provided are cord reinforcer manufacturing method and apparatus, which can improve the manufacturing efficiency of a cord reinforcer to be arranged in an annular reinforcing object and which can improve the manufacturing precision of the cord reinforcer.

Our products are characterised by precision and aesthetic production quality.

This increases the processing precision of the workpieces and simplifies the numerical control of the device.

Generally, the roughness of precision devices needs to be up to 0.1 micron.
