Overview

For extra large and heavy work piece the double column surface grinder is ideal for large plate, die mold, and ceramic plates. The different models available can grind workpieces of up to 20 ft (6,000 mm) long and 5 ft (1,500 mm) wide with high accuracy.

  • 47″ wide table, 55″ cross travel
  • Table length: from 78.7″ to 5″
  • Longitudinal travel: from 84.6″ to 4″
  • Automatic lubrication system
  • Oil temperature control
  • Bedway length is twice that of table length gives full support for the entire travel of the table, no table overhang
  • Bedway is designed with 2 v ways for perfect alignment of table travel, TURCITE coated to retain oil and resist friction

Features

Twice annealed castings Hydraulic table

All major castings, the base, columns and cross beams are twice annealed to maintain high accuracy during machining. This process relieves internal stress that builds up during casting process. It also provides vibration dampening , low rate of thermal expansion and superior wear resistant characteristics.

The hydraulic table has two single action cylinders and piston rods to ensure smooth and steady travel of large work piece. Specially designed directional valve eliminates table reversal shock during fast movement of the large table.

User friendly operation panel

Screen input allows automatic down feed of grinding wheel to the work piece in different sequences.

Input settings include:

  • Automatic rapid approach to work piece
  • Increment setting, minimum is 0.0001”
  • Spark Out setting up to 99 passes
  • SURFACE, PLUNGE grinding modes
  • Cross feed of wheel head
  • Synchronized movement of longitudinal and cross feeds
  • Panel is equipped with Electronic handwheel (MPG)

Efficient Down feed and Cross beam travel

Grinding head travels on ball screw along cross beam. It is supported at two levels by flat and dovetail fully gibed ways. It provides secured and precise cross movements controlled on the operating panel. Micro adjustment of the cross travel is done by a large handwheel. Cross travel is available with servo drive on linear ways as an option.

Vertical down feed travels on wo box ways driven by servo motor operated by MPG. It also has rapid traverse for quick positioning driven by AC motor.

Long table travels

The long work table travels on hardened and ground double V ways that are precision hand scraped and TURCITE coated for long lasting wear and great stability. The extra long base fully support the travelling table to avoid table overhang.
