Using a microscope to align the disc with the center of the mount.

tion can be performed by observing changes in ring displacement using a microscope during manual rotation, making the
calibration process straightforward.
" On the quality control front, " he continued, " we use
Renishaw XL-80 laser interferometers to check the accuracy of
our motion products and we are also considering whether to
add a few more units to cope with demand from increasing
orders and new factories. In addition to using ATOM readheads in our rotary tables, we also use a number of other
Renishaw encoders. For example, we use RGH series encoders
in our linear platforms, and RESOLUTE absolute optical
encoders in large rotary table applications. We are also testing
optical encoder systems that can operate in vacuum environments, " said Wu.

Results
The quick and easy installation and setup procedures of
Renishaw's compact encoders enable CPC to build competitive
DD products without sacrificing quality and performance.
" Renishaw optical encoders have provided us with extremely
reliable performance for many years, along with specifications
that meet all our customers' needs, " Wu said. " The dirt immunity
is superior to other encoder brands. It is very rare for us to experience any issues and the customer service is excellent. Encoder
setup is very simple; you just need to look at the color of the LEDs
on the readhead to check that it's been successfully installed.
" Direct-drive technology will become the mainstream due to
its advantages in terms of precision, efficiency, high response
rates, and durability. As we enter the Industry 4.0 age, the compatibility of hardware with systems and the issue of whether
they can communicate with each other will drive the biggest
trends in the development of motion control products. For this
reason, CPC will continue to invest more resources in this area
in the future, " said Wu.
