ACRA's new 1224AHD Automatic 3 Axis High Precision Surface Grinder is a state-of-the-art machine designed to deliver unparalleled accuracy, efficiency, and durability in precision grinding applications. Built with a focus on high accuracy, long accuracy life, superior surface roughness, high productivity, easy operation, and heavy-duty grinding capabilities, this grinder sets a new standard in precision technology. With its rigid construction, advanced features, and ergonomic design, the 1224AHD is the ideal choice for industries demanding the highest levels of precision and performance.
ACRA's 1224AHD Automatic 3 Axis High Precision Surface Grinder is a testament to precision engineering and advanced technology. The machine features heavy, extra-rigid castings for the main parts, ensuring accuracy at full capacity. The extra-wide table support provides superior rigidity and accuracy for long workpieces, while the X & Z slide ways are coated with "Turcite B" and precision hand-scraped for smooth, precise movement. The wheel spindle is supported at each end by duplex ball bearings, which are sealed to extend bearing life, and the entire spindle unit is replaceable for easy maintenance.
The 1224AHD boasts an advanced hydraulic circuit design that provides vibration-free reversing motion of the table, allowing for easy handling of the table by the handwheel when the table speed is switched off. The automatic lubrication system constantly pumps lubrication oil to every part of the slide way whenever the machine is powered on, with a flashing light indicating any lubrication issues.
Precision down feed is ensured by a precision-ground, vertical lead screw and transmission gears, while the table hydraulic feed offers a speed range from 1 m/min to 25 m/min (3 FPM-83 FPM). The automatic cross feed, powered by precision ball screws and a timing belt drive motor, provides quick and smooth cross feed operation. All slide ways and the electrical cabinet are protected from dust and water, ensuring long-lasting performance and accuracy.
