STANDARD FEATURES
•

2 Axis conversational CNC, semi-automatic or manual operations use hydraulic drive with control for table longitudinal movement

• High precision heavy duty spindle design uses a large diameter, cartridge type spindle with air-cooled, precisely balanced and totally enclosed spindle motor. Providing maximum support to the spindle are 6 pieces of class 7 (P4) permanently lubricated, angular contact ball bearings. This spindle design ensures extremely smooth surface finish and consistent accuracy
• Spindle head counterweight balance system - Pneumatic counterweights are installed in the spindle to eliminate backlash and prevent the premature wear of the elevating screws
• The column is made of high grade, dense cast iron which has been stress relieved. The computer aided design features a ribbed, honeycombed structure which resists flexing and vibration during heavy duty machining. The spindle travels on hardened and ground square ways
• The longitudinal slideways feature double "V" configuration instead of the usual "V" and flat design. The double "V" design improves the structural rigidity and stability of the front base. With Turcite B antifriction material lamination of the slideways, smooth and stable travel is consistently maintained during all kinds of machining conditions
• The crossfeed slideway system features a perfect mating of linear slideways, precision ballscrew and Mitsubishiฎ servo motor that provide high torque, speed and accurate positioning
• Smooth and accurate wheelhead movement - The wheelhead is positioned with a C3 grade ballscrew and driven by Mitsubishiฎ servo motor. The wheelhead guideways are laminated with Turcite B
antifriction materials and then precisely hand scraped
• Automatic wheel dressing with compensation feature dresses the wheel automatically during rough and/or fine grinding and at the end of rough grinding. This enables the machine to run unattended for hours making them ideal for high volume production runs
• A hydraulic temperature regulator is provided to minimize thermal expansion and maintain consistent accuracy and repeatability during heavy duty machining conditions
• An automatic lubrication system is standard for elevating leadscrew, column slideways, table guideways, and crossfeed ballscrew. The system uses a pressure sensor to monitor lubrication pressure. The machine shuts down automatically when the pressure drops below a preset level
• Shown model H2460II with optional accessories
• Voltage requires 220V/3 Phase/60 Hz.
NOTE: This machine requires special foundation preparations.
