The H3 Series high-precision step grinder tool grinding machine is body and components made of high-grade cast iron FC-30, which has been artificially normalized heat treated and then subjected to natural aging treatment. Component processing uses world-class equipment such as YASDA, MITSUI SEIKI, TOSHIBA, and ELB for one-time clamping processing. The precision dimensions can reach the micron level, ensuring high-precision grinding machines for the basic components of the equipment. Its design concept is consistent with a 5-axis high-precision CNC cylindrical grinder from Switzerland, which can use plunge or multi-layer peeling grinding methods, and integrates a 3-axis robot automatic loading and unloading system. The machine tool grinding diameter range is 0.5-20mm. The H3 step grinder is an ideal machine for tool blank preparation and processing of punches, complex-shaped molds and workpieces with large aspect ratios.
The H3 series step grinder uses high-precision penetration or multi-layer peeling grinding methods to process various parts, such as tool blanks, boring tool blanks, threaded parts, flat parts and non-round punches, etc.
Recently, Shanghai ANTISHICNC received an inquiry from a Russian company that specializes in making various cutting tools. The customer mainly makes punches, cutting tools, boring tools, threaded parts, special-shaped punches, etc. The customer’s main workpiece diameter range is 1-20mm, and he wants to improve processing efficiency. After the customer contacted us, we learned that the customer’s factory has several 5-axis CNC tool grinders, and we want to introduce an H3 step difference grinder based on the original 5-axis CNC tool grinder to do various tool blank preparation processes. We tell our customers that the workpieces processed by one H3 step grinder can simultaneously meet the material requirements of four 5-axis CNC tool grinders for blank parts, which can greatly improve processing efficiency.
