Hopper Fed Fully Automatic Double Miter Saw

 
 

Operation

When the machine is started, the work clamps on each side of the sawblades {vertical and horizontal }engage to firmly gold the material back against the fence and down against the table. Once clamping confirmation occurs, the sawblades descend and begin mitering.

When the sawblades leave their home position {up} the material feed station disengages and the station retracts the distance Programmed for the length of cut desired. When the sawblades return to their home position, the material feed station advances forward and the cycle begins over again The complete sequence is computer controlled and is based on sequence confirmations.

The positioning of the material feed station is numerically controlled via a non contact linear digital scale.

Optional Hopper Feed

On machines equipped with the optional hopper feed, when the machine completes cutting a length of material, it signals the hopper to advance and feed a new length of material and also ejects any remaining scrap from the previous length out of the machine.

A typical hopper set up can loaded with approximately 16 lengths of material .For unstable material profiles, custom dogs can installed on the feed belts. Feed belts can be quickly changed with dogs in place.

The hopper construction is simple and straightforward, no adjustments are normally required other than changing the feed belts if necessary. the unique horizontal layout allows for low cost design, easy, non-fatiguing material loading, non marking guides and dogs. The standard hopper will handle material lengths up to 12' {3600mm} long, optional supports are available for lengths beyond 12'.
