Tuda Heavy Duty Engine lathe — 50" swing x 200" lg (24" x 65" gap)
For roughing work, where stock removal is the key to profitability, Ewart-Ohlson has two large manual lathes. One of them has a gap allowing it to swing parts with irregular shapes up to 132”.
Our Machining Centers
Cincinnati Milacron 25 HC-1800 Horizontal Machining Center — X = 72" Y = 48" Z = 48" (4-Axis)
Cincinnati Milacron Maxim 630 CNC Horizontal Machining Center — X = 40.4" Y = 31.5" Z = 31.5
For smaller, lighter work, Ewart-Ohlson also owns two 4-axis horizontal machining centers, with machining envelopes up to 72” in X and 48” in Y and Z. These machines are ideal for rapid production of lighter weight parts.
Our CNC Horizontal Boring Mills
TOS Varnsdorf Heidenhein 426 Horizontal Boring Mill — X = 138" Y = 98" Z = 49" W = 31" with 5t
Lucas 40T Horizontal Boring Mill — X = 150" Y = 84" Z = 48" W = 72"
Lucas 40T Horizontal Boring Mill — X = 96" Y = 72" Z = 48" W = 72"
Lucas 300T 6" 4-axis CNC Horizontal Boring Mill — X = 84" Y = 84" Z = 84" W = 36"
Lucas 30T Horizontal Boring Mill — X = 84" Y = 84" Z = 48" W = 36"
Giddings & Lewis 70-G5-T CNC Horizontal Boring Mill — X = 132" Y = 72" Z = 58" W = 36"
The process of qualifying aircraft landing gear requires boring mills that can remove large amounts of stock rapidly and accurately. Ewart-Ohlson is equipped with seven 5” and 6” bar CNC horizontal boring mills for this purpose, with machining envelopes as large as 150” in X, 98” in Y, and 72” in Z. Two of these are five-axis machines, including 360,000 position tables. This gives Ewart-Ohlson the ability to perform highly accurate finishing operations as well as roughing operations where stock removal is paramount.
Our CNC Deep Hole Drilling Machines
