Engineered to deliver sub-micron flatness while slashing lifetime ownership costs by 40%, it excels in tool & die, aerospace bearing races, and precision mold base finishing. With ISO 2433-certified geometric accuracy and >95% mean time between failures (MTBF), it transforms grinding from a cost center to a competitive advantage—proving that true precision is measured not just in microns, but in decades.About DURAMA's Surface Grinding Machine1. Working principle: The surface grinder is mainly composed of components such as the bed, worktable, spindle, grinding head, guide rail, feed system, and lubrication system. The bed is the supporting structure of the entire machine tool, the worktable is used to place workpieces, and the spindle and grinding head are key components for achieving grinding operations. Surface grinders mainly use the rotation of grinding wheels to grind workpieces. During the grinding process, the grinding wheel rotates at high speed and continuously grinds the surface of the workpiece through contact with it, thereby achieving the required accuracy and surface quality.2. Scope of application: Surface grinders are widely used in the field of metal processing, suitable for grinding various metal materials such as aluminum alloys, steel, stainless steel, copper alloys, etc. Surface grinders are widely used in fields such as mold manufacturing and processing, mechanical manufacturing and parts processing, aerospace, automotive parts, optical lenses, clocks, and electronic components.3. Equipment advantages: The positioning accuracy and repeatability accuracy of the Durama surface grinder are both high, which can ensure high-precision machining of parts and is suitable for occasions that require high-precision machining. The Durama surface grinder can process multiple workpiece surfaces in one clamping, usually only detecting the first piece, eliminating many processes in ordinary machine tool processing and improving production efficiency. The machining process of the Durama surface grinder can be automatically completed according to the input program, and the operator only needs to perform initial tool alignment, workpiece loading and unloading, tool replacement and other operations, greatly reducing the physical labor intensity of the operator.Surface Grinding machine, surface grinder, grinder machine, grinding machine, milling machine....
