The stainless steel hexagonal nut with through-hole adjustable
screw. It is precisely processed by CNC. Precision Instruments & Optical Equipment Practical Products Microscope adjusting nuts, projector/lens fixing nuts, testing
instrument locking nuts, laboratory precision platform assembly
nuts CNC Production & Processing Features Extremely high requirements for concentricity, flatness and
perpendicularity (tolerance ≤ ±0.005 mm), with strict control over
the concentricity between internal threads and external contours. Multi-reference surfaces and internal threads are processed in a
single CNC clamping setup to ensure assembly accuracy and avoid
errors caused by repeated clamping. Fine-adjustment internal threads and limit slots can be
manufactured to meet the adjustment requirements of precision
instruments. Materials are mostly stainless steel and aluminum alloy, with
precision grinding to improve surface finish and dimensional
stability. Accurate positioning and reliable locking, free from loosening and
abnormal noise, preventing instrument accuracy degradation caused
by nut loosening. No displacement or shaking in precision-sensitive optical systems
(such as lenses), ensuring accurate testing and observation data. Fine-adjustment nuts feature smooth and consistent adjustment
without jamming, improving operator experience and meeting
high-precision requirements in laboratories and testing
applications. Common CNC Machining Issues & Key Points Accuracy deviation issues Repeated clamping easily causes out-of-tolerance concentricity and
flatness, as well as misalignment between internal threads and
external contours. High-precision fixtures and single-setup processing are required. Real-time dimensional monitoring during machining is necessary to
avoid accuracy deviations due to thermal deformation. Fine-adjustment thread machining issues The lead of internal threads in fine-adjustment nuts must be
precise. Lead deviation often results in poor adjustment smoothness and
insufficient accuracy. Strict control of thread machining accuracy, use of special taps,
and post-machining lead inspection are required to ensure
consistent adjustment feel. Surface precision grinding issues Surface waviness, scratches and internal thread burrs often occur
after precision grinding. High-precision grinding machines must be used with controlled
grinding speed and feed rate to ensure surface roughness Ra ≤ 0.8
μm. Finishing after tapping is required to remove thread burrs. Limit structure machining issues Dimensional deviations in limit slots will cause abnormal
adjustment travel. Precise machining of limit slots is required to match the internal
structure of the instrument. Travel testing after machining is necessary to avoid limit failure
and ensure instrument adjustment accuracy. We have introduced advanced equipment and technology from Japan and
