A progressive die, also known as a sequential die, is a die that consists of multiple stations that are sequentially linked to accomplish different processes. In one stroke of a press, a progressive die can perform a series of different stamping processes, such as profile punching, internal and external punching, punching, bending, and deep drawing. The hardness of the die kernel of the progressive die after heat treatment reaches 58~68 HRC, and the dimensional accuracy of the die kernel also has high requirements. Gesac SH360 series of high hardness steel machining end mills are able to meet the high precision, high quality and long life processing requirements of progressive dies. This issue focuses on the case of progressive mold machining.
For progressive mold cavity roughing, the material is ASP60, the hardness is 65-68HRC, the customer's original plan to use a flat bottom tool processing, roughing requires 3 tools to complete processing; according to the processing material characteristics and hardness, our company recommended the use of SH360 series D10 * R1 specifications 4-edged rounded head cutter, our tool roughing only one tool to complete the processing, the machining efficiency to increase by 43% to help customers reduce costs and increase efficiency. 43%, to help customers realize cost reduction and efficiency.
For the finishing of the bottom surface of the cavity of the progressive mold, the required finish in Ra0.2-0.4, the customer's original program using a flat-bottomed cutter light cutter, in order to prevent the tip of the knife chipping, can only reduce the feed, need to be processed 4 times in order to ensure that the finish is up to standard. According to the customer's demand, our company recommended to use SH360 series D6*R0.2 specification 4-flute rounded head cutter, change the flat head cutter to R0.2 rounded head cutter, not only effectively protect the cutter tip, at the same time can be optimized for the finishing parameters, the finish of the workpiece after finishing to meet the customer's demand, the machining efficiency is shortened by 50%.
