Hy-Tech Grinders Have High Power-to-Weight Ratios
Heavy-duty industrial air grinders offer power ranges from .5hp to 4 hp.
Hy-Tech Engineered Solutions’ ATP Cyclone Grinders is a series of heavy-duty industrial air grinders that have high power-to-weight ratios in power ranges from 0.5 hp to 4 hp. According to the company, the grinders are designed to deliver higher productivity in demanding metal finishing environments, such as fabricated metals, ship building and a variety of MRO applications, including refinery, power generation and structural steel.

The company says that the grinders’ consistent power output maximizes metal removal efficiencies and operator productivity. The series comprises 44 standard models featuring powerful governed controlled motors; stainless steel, corrosion-resistant governors; standard and extended length horizontal models, with up to 36” extensions; true 3 hp and 4 hp vertical and horizontal performance; and a comfortable design.
Immersion tin and lead-free hot air solder leveling (HASL) coatings based on SnCu or SnAgCu alloys are widely used as surface finish materials for printed circuit boards (PCB). These coatings prevent the underlying copper from corrosion and preserve its solderability during lead-free assembly processes and for a long storage life of PCBs.
Surface finish types for commercially supplied stainless steel sheet are detailed in various standards. ASTM A480-12 and EN10088-2 are two; BS 1449-2 (1983) is still available, although no longer active. These standards are very similar in that they define eight grades of surface finish for stainless steel. Grade 7 is “buff polished,” while the highest polish—the so-called mirror polish—is designated Grade 8
