Air-operated high-frequency reciprocating polishing pen
Air-operated high-frequency reciprocating polisher UTR-70 (stroke 0.7mm)
For fine polishing of mold finishing. Air-operated high-frequency reciprocating polishing machine UTR-70.
The UTR-70 is an air-operated high-frequency reciprocating polishing machine that is ideal for finishing molds and precision parts. With a reciprocating stroke of 0.7mm, it allows for stable polishing and surface finishing of fine details. The spindle is heat-treated to suppress stroke deficiency caused by spindle retraction during polishing, thereby improving work efficiency. It is compatible with 3mm round collets and square collets (0.5–3mm × 4–10mm). It has low air consumption (0.04m³/min) and is easy to handle. We also offer OEM/ODM support and are open to discussions on specification changes.

Applications/Examples of results
Mold and narrow area polishing: The angled head stabilizes posture even in hard-to-reach areas, contributing to improved workability. Internal diameter polishing (holes, grooves, corners): It is easy to control polishing and finishing in small diameter areas, helping to reduce polishing unevenness and suppress reprocessing. Flat surface polishing/surfacing: Stable contact contributes to uniform finishing and reduced work time. Fine finishing (high-frequency reciprocating type): The back-and-forth motion allows for high adaptability in fine surface finishing, contributing to quality stabilization. Long-duration work: The low vibration and low noise design supports the reduction of operator burden. *Effects may vary depending on the work material, tool conditions, work methods, and maintenance status.
