&bull; High accuracy<br />&bull; Long accuracy life<br />&bull; Superior surface roughness<br />&bull; High productivity<br />&bull; Easy operation<br />&bull; Heavy duty grinding<br />We&rsquo;ve carefully considered the following:<br />&bull; Fully-support of each slide way.<br />&bull; Rigidity and damping effect of each main parts such as base, column, saddle, spindle &amp; grinding head, etc.<br />&bull; Dust-free protection of all slide ways as well as spindle unit.<br />&bull; Ergonomic engineering of each hand wheel and control lever.<br />Features:<br />Rigid Construction:<br />&bull; Heavy, extra rigid castings are used for the main parts to assure accuracy at full capacity of grinder.<br />Built for Precision:<br />&bull; Extra-wide table support provides superior rigidity and accuracy for long work pieces. X &amp; Z slide ways are coated with &ldquo;Turcite B&rdquo; 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.<br />Advanced Hydraulic Circuit Design:<br />&bull; Improved hydraulic circuit provides vibration-free reversing motion of table. Easy to handle the table by hand wheel when table speed is switched off.<br />Automatic Lubrication:<br />&bull; 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.<br />Precision Down Feed:<br />&bull; A precision ground vertical lead screw and transmission gears unit provide accurate down feed.<br />Completed Dust Protection:<br />&bull; All slide ways and electrical cabinet are well protected free from dust and water to assure longer accuracy and for easy maintenance.<br />Table Hydraulic Feed:<br />&bull; Speed range from 1 m/min to 25 m/min (3 fpm-83 fpm) provides easy operation of machine.<br />Automatic Cross Feed:<br />&bull; A combination of precision ball screw and a timing belt drive motor provides quick and smooth cross feed.<br />&bull; Proximity switches are installed inside.<br />&bull; Stroke is adjustable by push button.<br />&bull; Box-type column provides excellent damping effect.<br />&bull; Lubrication oil tank be taken out easily for cleaning.<br />&bull; Cartridge spindle adopts precision bearings class ABEC 7 (P4).<br />&bull; Enlarged Double Vee and extra-long slide way on base.<br />Completed Dust Protection:<br />&bull; All slide ways and electrical cabinet are well protected free from dust and water to assure longer accuracy and for easy maintenance.<br />&bull; Extra-strong saddle and slide way for fully support.<br />&bull; High efficient variable pump is used for saving energy and lowering the temperature.<br />&bull; Separated from machine body for vibration-free and easy maintenance.<br />&bull; Hardened &amp; ground vertical lead screw and transmission gear.<br /><br /><br />Specifications:<br />Capacity:<br />&nbsp; &nbsp; &nbsp;Maximum Grinding (Length x Width):&nbsp; &nbsp; &nbsp; &nbsp;
