Performance
Our protection spiral is a machine tool component jointly developed by us and one Italian company, with unique functions to protect NC lathe, machining center, hydraulic machine tool, various shafts, rods, and ball screws from chips, dust, and liquid damages. It also enables precision operation and increased service life of machine tool in addition to adding decorative touches to the equipment.

Structures
This series of protection spiral is made of premium spring steel strips that have been sent through heat treatment. It is usually installed onto the flanges at both ends of protected parts, forming a non-contact connection with the parts. Elastic force produced by the pre-stressed spiral acts on the connection, ensuring a secure joint. During operation, the spiral freely extends or compresses while creating little noise. Its black color goes well with most of the flange parts on the machine tool.
