Description
- Made in Taiwan
- ACRA’S 1020AHD Automatic 3 Axis High Precision Surface Grinder is a distinction in precision technology, that is built to fulfill the idea of:
- High accuracy
- Long accuracy life
- Superior surface roughness
- High productivity
- Easy operation
- Heavy duty grinding
- We’ve carefully considered the following:
• Fully-support of each slide way.
• Rigidity and damping effect of each main parts such as base, column, saddle, spindle & grinding head, etc.
• Dust-free protection of all slide ways as well as spindle unit.
• Ergonomic engineering of each hand wheel and control lever. - Rigid Construction:
• Heavy, extra rigid castings are used for the main parts to assure accuracy at full capacity of grinder. - Built for Precision:
• Extra-wide table support provides superior rigidity and accuracy for long work pieces. X & Z slide ways are coated with “Turcite B” and precision hand scraped. Wheel spindle is supported at each end by duplex ball bearings which are sealed for long life. Entire spindle unit is replaceable as a cartridge. - Advanced Hydraulic Circuit Design:
• Improved hydraulic circuit provides vibration-free reversing motion of table. Easy to handle the table by hand wheel when table speed is switched off. - Automatic Lubrication:
• The lubrication oil pumped to every slide way all the time whenever the machine is power on. A flashing light will be actuated when the lubricating function is not working. - Precision Down Feed:
• A precision ground vertical lead screw and transmission gears unit provide accurate down feed. - Completed Dust Protection:
• All slide ways and electrical cabinet are well protected free from dust and water to assure longer accuracy and for easy maintenance. - Table Hydraulic Feed:
• Speed range from 1 m/min to 25 m/min (3 fpm-83 fpm) provides easy operation of machine. - Automatic Cross Feed:
• A combination of precision ball screw and a timing belt drive motor provides quick and smooth cross feed.
• Proximity switches are installed inside.
• Stroke is adjustable by push button.
• Box-type column provides excellent damping effect.
• Lubrication oil tank be taken out easily for cleaning.
• Cartridge spindle adopts precision bearings class ABEC 7 (P4).
• Enlarged Double Vee and extra-long slide way on base. - Completed Dust Protection:
• All slide ways and electrical cabinet are well protected free from dust and water to assure longer accuracy and for easy maintenance.
• Extra-strong saddle and slide way for fully support.
• High efficient variable pump is used for saving energy and lowering the temperature.
• Separated from machine body for vibration-free and easy maintenance.
• Hardened & ground vertical lead screw and transmission gear. - Note: Chuck Control Must Be Ordered Separately with Any Electro Magnetic Chuck.
