That's what separates a production grinder from a toolroom machine: consistent finish across the whole surface, without depending on how evenly someone cranks a handwheel.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe way construction is where the accuracy lives.\u003c\/strong\u003e Double longitudinal \"V\" ways and cross \"V\" ways on both table and saddle, hand scraped and Turcite coated. Turcite is a low-friction bearing material bonded to the sliding surface; combined with hand scraping it gives smooth, chatter-free travel that stays accurate as the machine wears. The castings are annealed for stability, so the machine holds its geometry over years rather than settling out of tolerance.\u003c\/p\u003e\u003cp\u003eThe hydraulic table carries over-travel protection and preset speed control. You dial a table feed rate anywhere from 6 to 83 feet per minute and get that exact rate every time the table is engaged — no drift between setups, no re-finding the right speed for a repeat job. Auto crossfeed runs in both intermittent and continuous mode, so you can step over between passes or feed continuously for a finishing sweep.\u003c\/p\u003e\u003cp\u003eTwelve by twenty-four inches of table with a 20-inch center height handles die plates, mold bases, fixture surfaces, and machine ways. A 3 HP spindle turns a 14-inch wheel at 1,720 RPM.\u003c\/p\u003e\u003ch2\u003eKey specs\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTable size:\u003c\/strong\u003e 12\" x 24\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax grinding size:\u003c\/strong\u003e 11\" x 24\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter height:\u003c\/strong\u003e 20\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpindle:\u003c\/strong\u003e 3 HP, 1,720 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrinding wheel:\u003c\/strong\u003e 14\" x 1.25\" x 5\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomation:\u003c\/strong\u003e 2-axis auto — longitudinal and cross feed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTable speed:\u003c\/strong\u003e preset hydraulic control, 6–83 FPM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth align=\"left\"\u003eModel\u003c\/th\u003e\n\u003ctd\u003eSH-1224-2A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth align=\"left\"\u003eType\u003c\/th\u003e\n\u003ctd\u003eTwo-axis automatic surface grinder\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth align=\"left\"\u003eTable size\u003c\/th\u003e\n\u003ctd\u003e12\" x 24\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth align=\"left\"\u003eMaximum grinding size\u003c\/th\u003e\n\u003ctd\u003e11\" x 24\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth align=\"left\"\u003eCenter height\u003c\/th\u003e\n\u003ctd\u003e20\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth align=\"left\"\u003eSpindle motor\u003c\/th\u003e\n\u003ctd\u003e3 HP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth align=\"left\"\u003eSpindle speed\u003c\/th\u003e\n\u003ctd\u003e1,720 RPM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth align=\"left\"\u003eGrinding wheel\u003c\/th\u003e\n\u003ctd\u003e14\" x 1.25\" x 5\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth align=\"left\"\u003eAutomatic axes\u003c\/th\u003e\n\u003ctd\u003e2 — longitudinal and cross\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth align=\"left\"\u003eCrossfeed modes\u003c\/th\u003e\n\u003ctd\u003eIntermittent and continuous\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth align=\"left\"\u003eTable drive\u003c\/th\u003e\n\u003ctd\u003eHydraulic with over-travel protection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth align=\"left\"\u003eTable speed range\u003c\/th\u003e\n\u003ctd\u003e6–83 FPM, preset control\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth align=\"left\"\u003eWay design\u003c\/th\u003e\n\u003ctd\u003eDouble longitudinal \"V\" ways and cross \"V\" ways, table and saddle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth align=\"left\"\u003eWay treatment\u003c\/th\u003e\n\u003ctd\u003eHand scraped and Turcite coated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth align=\"left\"\u003eBed\u003c\/th\u003e\n\u003ctd\u003eExtra wide\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth align=\"left\"\u003eCastings\u003c\/th\u003e\n\u003ctd\u003eAnnealed for machine stability\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth align=\"left\"\u003eCoolant system\u003c\/th\u003e\n\u003ctd\u003e12 gallon\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth align=\"left\"\u003eVoltage\u003c\/th\u003e\n\u003ctd\u003e220V or 440V (specify at order)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth align=\"left\"\u003eOptional\u003c\/th\u003e\n\u003ctd\u003eNC spindle downfeed with ballscrew and servo feed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch2\u003eWhat ships with the grinder\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eGrinding wheel, 14\" x 1.25\" x 5\"\u003c\/li\u003e\n\u003cli\u003eAutomatic lubrication system\u003c\/li\u003e\n\u003cli\u003e12 gallon coolant system\u003c\/li\u003e\n\u003cli\u003eWheel adapter and flange\u003c\/li\u003e\n\u003cli\u003eWheel balancing arbor and balancing stand\u003c\/li\u003e\n\u003cli\u003eDiamond dresser\u003c\/li\u003e\n\u003cli\u003eSplash guards, front and back\u003c\/li\u003e\n\u003cli\u003eTool kit — machine manual, half nut wrench, 17mm and 19mm wrenches, set of six Allen wrenches, Phillips screwdriver, oil can, grease gun, rear way cover bracket, indicator pin, can of touch-up paint\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eManuals and documentation\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/sharp-industries.com\/parts-books\/\" target=\"_blank\" rel=\"noopener\"\u003eSharp Operators and Electrical Manuals Library — SH-1224 Instruction Manual and Parts List\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e\u003ch2\u003eOrdering and freight\u003c\/h2\u003e\u003cp\u003eShips by freight and needs rigging rather than a curbside drop.
