STANDARD FEATURES
• Column type high precision 3 axis fully automatic programmable controlled model, the grinder is suitable for mass production
• Programmable controlled grinding machine, the machine with micro processor is programmed to perform rough grinding, fine grinding spartout passes, automatic overwheel dressing and compensation for wheel dress amount. After grinding, table can be set to park either left end or right end. Spindle can be set to stop running or keep running and wheelhead can also be set to lift up to start point or reference point after grinding cycle finished
• Rigid construction, all essential castings are made of high grade dense cast iron which has been stress relieved and ribbed with honeycomb ribs to enhance rigidity and increase stability thereby increasing cutting capability
• The column is made of high grade dense cast iron which has been stress relieved. With ribbed with honeycomb type ribs and computer analyzed structure, the stability and rigidity is greatly increased
• The rigid wheelhead houses a large diameter cartridge type spindle supported by six pieces of class 7 P4 super precision angular contact ball bearings which have been accurately measured, selected and preloaded, and then assembled in a temperature controlled room. Spindle is permanently lubricated and requires no maintenance. The precisely balanced spindle motor is air cooled to ensure optimum surface finishes and maintain superior accuracies
• Spindle travels on hardened and ground square ways, and is driven by ballscrew and an AC servo motor for heavy grinding and smooth and accurate movement. The downfeed repeatability within 0.000080" guaranteed
• Hydraulic spindle counter weights balance system is installed to eliminate backlash and wear of elevating screw
• The table is full supported on the well designed front base of machine, thus, the accuracy is greatly increased. The permissible loads can be completely supported and table overhang is eliminated
• Completely supported guideways, extended base guideways for crossfeed and longitudinal travel enhance machine rigidity and stability and upgrade machine accuracy and longevity
•

Longitudinal slideways with double V guideways which are laminated

with Turcite B anti-friction material and precisely hand scraped to

ensure high accuracies for smooth and stable longitudinal movement.

Continuous lubrication is provided to assure smooth stick-slip free

movement of the table and accurate positioning

•

Longitudinal stroke adjustment device, table reversal is controlled

by proximity switches which never make contact. It is simple for

operator to adjust table reversal to minimum required stroke, thereby

grinding less air and reducing grinding time. Stroke adjustment

protection plate is designed to allow table stroke to be adjusted safely

•

Crossfeed slideways, hardened and ground guideways are laminated

with Turcite B, then precisely hand scraped. Continuous lubrication is

provided to ensure smooth stick-slip free movement of the table and

accurate positioning

• Crossfeed transmission mechanism, enlarged precision leadscrew with backlash adjustment device is driven by an AC motor. The encoder type stroke setting key allows crossfeed reversal points to be set from operator's control panel, thereby working efficiency is increased
• Crossfeed stroke setting, the crossfeed travel is set with push buttons on control panel. This new break through in design is more efficient and user friendly
• Crossfeed speed control, column continuous movement speed is controlled by a frequency converter for obtaining better grinding surface finish and better dressing result from table
• Automatic wheel dressing with compensation, the machine efficiency is maximized by overhead parallel dressing with automatic dressing compensation system during rough and/or fine grinding and at the end of rough grinding. This allows machine to run unattended and reduces machining costs
• CBN Wheel dressing and crisscross grinding
• Automatic lubrication system provides lube oil to saddle ways, column ways, crossfeed and elevating screws. This system minimizes the chance of wear due to negligent operation and ensures the machine accuracy and prolongs the life of the machine
• The interlock between electrical cabinet door and power supply to ensure safety operation
• Model FSG-2440ADII as shown with optional accessories
• 220V/3 Phase/60 Hz. Electric. 440V/3 Phase/60 Hz. transformer available as options
NOTE: This machine requires special foundation preparation,
           please call for more details.
