| 2).Material and treatment Selection of tool material (Type of material) is very important in terms of the quality of the processed product and the tool life (processing cost). This time, we summarized the typical material for tooling. We use the following material for Punch body and Die. |
M2 (SKH51) It is one of the most widely used materials among M2. Compared to D2, it is a material excellent in abrasion resistance, impact resistance and toughness. It is suitable materials such as stainless steel and a large amount production D2 (DC53) It is a typical tool steel for sheet metal processing which is excellent in mechanical properties and heat treatment characteristics. We adopt Super-subzero treatment to further improve wear resistance. ASP-23 It is chromium molybdenum vanadium powder high speed steel. It has the characteristics of high wear resistance (anti- abrasive wear), high compressive strength, very good harden ability, and good toughness. |
| 3).LIFE COUNTERMEASURE FOR TOOLING | |
| TiCN Coating : Ticn treatment to our premium high speed steel. Hardness of surface is Hv2,700 - 3,000 which is harder than Tin coating. |
BHTIE coating treatment |
|
NARROW PUNCH There is a punch type such as narrow type, open end type, super narrow type etc. which made it difficult to break by shortening the effective punch length and increasing the strength of the punch |
|
THICK PLATE PROCESSING A tool that provide taper relief on the punch and reduce seizure and contact with the material. |
| OTHER LIFE COUNTERMEASURES -.Check for misalignment of turret station and wear of turret key etc. -.Combined use with tools for slug pulling measures. -.Implementation of early regrinding. -. Put a small rounding on the corner of Square / Rectangle punch. As life countermeasures of the tool, it is recommended to select a tool that is acceptable for the processing conditions such as the quality and thickness of material. |

-.The shear resistance should be about 80% of the tensile strength as a guide.
-. Please multiply x 1.4 to the calculation result in case of more than 3.2mm thickness.
-. Please calculate based on the number of shear resistance and Tensile strength for the material which is unspecified on the left table.
-. If there is a workpiece, please actually perform punching and purchase the appropriate clearance referring to the table below.
-. The minimum clearance is depends on machine specifications. Please also check the machine specifications.
