 Aggressive Grinding, a small US family owned business (President Lester Sutton at left) has bought four new Usach 100-T4 multi-spindle CNC ID/OD grinding machines from another small US family owned business (President Giacomo Antonini at right). The machines will be delivered in 2012 and the order will create new jobs at both companies - once again small businesses creating well-paying jobs in the US.

New Year - A Good Start!

Once again, Usach's production machines have been chosen by the automotive industry. Following GM North America's award of a multi-million dollar contract last year, an even larger order has just been awarded to us by GM's Chinese partner. This large order is for high production machines to simultaneously grind ID's and OD's of transmission shafts. This order was won against strong competition from Germany demonstrating that we successfully compete against our well established European competition!

US Manufacturing Companies Prefer Our Large Production OD Grinders

Manufacturer of equipment for the railroad, marine, mining, drilling and energy generation industries as well as a world renowned manufacturer and supplier of machined parts serving the power generation, mining, transportation, nuclear, aerospace and marine industries have selected our large OD grinders.

A Cute Story!

We recently delivered a Usach 100 grinder in Virginia where the epicenter of the recent east coast earthquake was located. The machine operator told us he literally hit the "go button" on a grinding cycle as the earthquake started. He was very proud to tell us that the Usach 100 performed flawlessly and the part was perfect despite the turmoil.

Neither rain nor sleet nor earthquake stops a Usach grinder from doing its job!!

Just Completed!
