The rectangular section ALMA machines (AL series) are designed to withstand high specific weight media (stainless steel media, high density media, porcelain) suitable for polishing and burnishing cycles. You can also use plastic and ceramic media for the usual deburring and smoothing cycles.

AL Series are available both at 1,500 rpm (for deburring, smoothing and polishing) and at 3,000 rpm (burnishing with stainless steel media).
