Planer Mill Work
Planer mills are machine tools with two methods of removing stock from workpieces. The planer head holds a single point tool in a fixed position and the workpiece moves beneath the tool removing stock. The milling head holds tooling such as endmills and inserted shell cutters for removing stock in typical milling practices. The planer mill is well suited for long straight cuts or when cuts of varying angles are required. The milling head can remove a large amount of material quickly.
The plane mill at Withers Tool, Die and Manufacturing has a table size of 54” x 240”. There are dozens of different shaped single point tooling and the largest cutter for the milling head is 12” diameter and can cut up to 0.300” in A36 HR steel. The planer mill is very useful in establishing datum surfaces on weldments for use in set up for later machining.
