2.3 WORK FLOW
Packaging of Chrome Plated Bar/Linear shaft (Hard shaft/Flexible shaft):
Shanghai Metal Products are packed and labeled according to the regulations and customer's requests. Great care is taken to avoid any damage which might be caused during storage or transportation. In addition, clear labels are tagged on the outside of the packages for easy identification of the product I. D. and quality information.
A. Wooden Case
B. Carton Packing
C. Straw Rope
D. Air Cushion (film) Bag
The linear shaft can be divided into hard shaft and soft shaft according to the hardness of heat treatment.
Hard shaft is quenched by high frequency quenching on surface, and its surface hardness is generally about HRC60. Hard shafts are suitable for use with linear bearings.
Flexible shaft is not quenched by high frequency, the hardness is generally HB200~300, equivalent to HRC25 or so. Soft shafts are not suitable for use with linear bearings.
