Acra’s new NC Controlled Fully Automatic 3 Axis Super Precision Surface Grinder is packed with features and is operator friendly.  Here are a few of its features:

  • Grinding Area of 16”x 32”
  • Table to Spindle Center is 27.5”
  • Vertical Feed is driven by Servo Motor
  • High Precision Linear Guide Ways on Vertical Slide Ways
  • Longitudinal Feed has a Hydraulic drive
  • Cross Feed is driven by AC motor
  • Conversational NC Computer Controlled

Precision Spindle

  • The Spindle is directly driven by a Class V-3 Motor and is supported by 5 super-high precision bearings. The high precision spindle assures superior rigidity and quality of grinding.

Easy To Adjust Cross Travel

  • Automatic Cross Travel is controlled by non-contact proximity sensors, allowing for easier adjustment and extended service life.

Ball Screws on Cross Feed

  • The Cross Feed employs precision ball screws. The ball screws are protected by bellow covers to ensure their service life. With sealed grease lubrication, further lubrication is not needed.

Table Longitudinal Feed

  • Variable Table Feed speed ranges from 1 to 25 M/min (3-83ft./min). Table Reversed movement is controlled by the advanced proximity sensor with built-in design for safety. 

Advanced Hydraulic Circuit Design

  • The Machine is designed with an advanced hydraulic circuit that reduces shock to a minimum when the table transverses at the end of travel. The hydraulic power unit is separate from the machine to avoid vibration and heat transferring to the machine. 

TS series NC Control

  • Fully Automatic
  • User-friendly
  • The control box swings to any direction to facilitate operation
  • The control box is provided with an MPG hand wheel. It increases convenience for test grinding and work piece setup.
