Grinder is programmable to 10 millionths accuracy.

Press Release Summary:

EZ-Surf XA Surface Grinder combines Newall Microsyn digital linear encoders with software specifically designed to interface with scales. It permits machinist to operate in manual, semi-automatic or fully automatic modes. EZ-Surf comes with 7 in. wheel with 8 in. wheel capacity, integral 2-diamond wheel dress, 3 in. diameter spindle, and 1.5 HP continuous-duty spindle motor. It provides 100 ipm rapid transverse for vertical y-axis and cross feed z-axis.

Original Press Release:

Bridgeport's New EZ-Surf Grinder Programmable To 10 Millionths Accuracy Is The Most Precise In Its Class

(Bridgeport, CT - January 2002) "We are America's only domestically manufactured surface grinder, and now we are introducing a model which is the most accurate in the world, within its class" boasted Harig Product Manager Robert Beattie, as he announced the new Bridgeport/Harig EZ-Surf XA. The high precision capabilities of the new EZ-Surf will be demonstrated at the Bridgeport WESTEC booth #3201.

The key is the addition of Newall Microsyn Digital Linear Encoders combined with the Bridgeport/Harig (A Goldman Industrial Group Company) development of new software specifically designed to interface with the scales. A new 5 place decimal display enhances the EZSURF XA resolution to 10 millionths with the resultant accuracy in the machine. It is repeatable within '1 Micron'. "This development makes the XA a very inexpensive alternative in the high precision arena." Adds Beattie.

The EZ-Surf XA permits the machinist to operate in the manual, semi-automatic of fully automatic modes. This flexible and now very high precision machine is built to the rugged standards incorporated into all Bridgeport machines. This includes a cast iron base with three point leveling. An automatic continuously circulating lubrication system, hand scraped ways and ground internal parts add to the precision operation and long life. The two-axis PC control is at eye level for increased operator accessibility.

The EZ Surf comes with a 7" wheel with an 8" wheel capacity and integral, 2-diamond wheel dress with wheel dress compensation. There's 100 ipm rapid transverse for the vertical y-axis and cross feed z-axis. The hydraulic, longitudinal table feed with on/off control, soft hydraulic regulating valve is ideally suited for speeds from 3 fpm to 70 fpm standard. The operator has the choice of standard or slow (.250 ipm to 30 fpm) longitudinal feed. The 3" diameter spindle with class 7 pre-loaded ball bearings and 1.5 HP continuous duty spindle motor make the EZ-Surf a reliable machine for long life.

"The manufacturing industry continuously presses for non-compromising precision in all sectors. With the EZ-Surf XA, we feel we are able to match precision with anybody for the
applications where we have been producing quality parts for over 75 years."
