The ACER SUPRA-1020AHD is a sophisticated High Precision Surface Grinder designed for manufacturers requiring fully automated and accurate grinding of parts up to 10 inches by 20 inches. The machine’s foundation is a reinforced high column and heavyweight Meehanite casting, providing unmatched rigidity and thermal stability essential for maintaining long-term precision.

Its movements are controlled by a 3-Axis Auto Movement system, which incorporates a powerful Hydraulic Table with variable speeds from 16 to 80 FPM and an Electronic Cross Feed for consistent, automated processing. The spindle is a direct-drive unit supported by four ABEC-7 angular contact ball bearings for minimal runout and a top speed of 3,500 ^RPM.  Movement precision is ensured by Precision Turcite-B-coated ways on all axes. The Auto Incremental Downfeed feature allows for micro-adjustments as fine as 0.0001 inch, enabling both auto surface and plunge grinding operations. Additional standard features enhancing the machine’s durability and ease of use include an Automatic Lubrication System for the slideways and screws, and an Enhanced Rapid Elevation function for quicker setup and operation.
