CNC surface grinding machine CNC double-column surface grinding machin

Joen Lih Machinery Co., Ltd., established in Taichung of central Taiwan in 1988, is one of Taiwan’s specialized manufacturers of a variety of surface grinders, including high precision CNC profile surface grinders, hand-operated surface grinders, and semi-automated precision surface grinders.

Recently the company debuted new high-precision wafer grinding machines for the high-tech industry. The models inherit much from a vertical grinding machine in terms of design. A diamond-outfitted grinding wheel is fitted to the floating spindle, and the machines perform vertical grinding on hard and brittle workpieces requiring the highest degree of surface accuracy and flatness.

Beyond wafers, the machines are designed for use with ceramics, quartz, glass and gems. The motor of the machine is built in the air-floating spindle. Variable spindle speeds range from 1,000 to 5,000rpm. The rapid traverse rate is 300mm/min, and a powerful Fanuc Oi-series controller provides full digital control.

The wafer-grinding machine comes with a diamond-outfitted grinding wheel, ceramic vacuum suction table, spindle temperature controllers, vacuum pump, and toolbox. There is also an optional precision air dryer, height gauge, and high-precision spindle.

The machine is equipped with a high-performance temperature controller, employs a highly efficient plate-type heat exchanger, and has a comprehensive safety protection device to ensure safe operation. The optional air dryer removes dust in the compressed air and has a highly accurate pressure and temperature control.

Joen Lih mainly sells high-precision wafer surface grinding machines to Southeast Asian countries, the United States, and Canada. The company will attend the 2011 Taipei International Machine Tool Show, slated for March 1-6, at the L-610 booth at the Nangang TWTC Exhibition Hall.
