About the Mill Accordion Way Cover Set for the NexGen Mill
The way cover set for the 5800 NexGen mills was designed to cover the larger 18″ base of the Y-axis. Both the front and backside covers utilize double accordions for the longer base, while an additional aluminum plate is sandwiched between the two covers. This additional plate helps to keep the covers from arching up when the mill table is pushed toward either end of the Y-axis (either handwheel end or mill column end).
The way cover material is made of polypropylene. It is durable and resilient enough to better withstand the temperature of hot chips. The material itself is 10 mil (mil=0.001″).
The rear cover slips over the column. The front plate set is held in place with another spring that wraps under the stepper motor mount (CNC machines) or under the handwheel thrust collar (Manual machines). The two inner plates are held against the saddle using two 4″ long 10-32 bolts. A longer saddle lock thumbscrew is also provided to give your fingers room for adjustment with the long bolts in place. Complete, illustrated step-by-step instructions are included, and installation takes only a few minutes.
NOTE: This Y-axis cover was designed to work on Sherline machines. They were not designed to work with any aftermarket parts such as limit switches, stops, etc.
Front and rear cover sets have the accordion plastic covers already riveted in place. Included are the front and rear cover set, two attachment bolts and locking nuts, two attachment springs (one already attached to the rear cover set, and an extra-long saddle lock thumbscrew).
CAUTION: The way covers will not work if you have done any customization to the mill base ways, such as adding sensors. They cannot slide over any impedance that you may have added.
Always wear safety glasses when operating machine tools.
