2).BHT Tooling Advantages	Taking into consideration our clients wishes, every day we work to satisfy our clients' needs, to increase our product list and tools quality. √ We produce our punch tooling from high speed steel M2(SKD), D2,(SKH). working surfaces are preciously grounded, standard will be whole body Total Hardening, the hardness can reach HRC61-63. √ we have we have more than 17 years experience in punch tooling manufacturing. √ Our punch tooling factory total have 102 people, total have around 150 sets processing machines for punch tooling. now most machines are CNC and from China local top manufacturer, but also we have 8 sets of processing machines from Japan and Europen, like CNC Machine Center from MIKRON, CNC EDM from Sodick etc... √ The tolerance for the punch is 0,+0.01mm √ Every special punch forming tooling will be tested by our punch machines and have the test samples before sending to our clients.
3).LIFE COUNTERMEASURE FOR TOOLING
	TIN / TICN coating PROCESSING
	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.
4). MATERIAL FOR TOOLING
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. D2 (SKD) , M2 (SKH)
We use the following material for die. Improved D2 , M2(SKH)

5). REFERENCE APPROPRIATE CLEARANCE Clearance = material thickness x clearance ratio
Material	Clearance ratio		Tensile Strength (N/mm²)
	Servo-Hydraulic Machine	Mechanical Machine
Mild Steel(Cold Roll)	0.2-0.25	0.15	More than 270
Mild Steel(Hot Roll)
Stainless(Hard)	0.25-0.3	0.2	More than 520
Stainless(Soft)			More than 450
Aluminum(Soft)	0.15-0.2	0.1	More than 95
Aluminum(Hard)			More than 215
Copper	0.2-0.25	0.15	More than 275
Brass	0.2-0.3	0.2	More than 410
High Tensile Steel			More than 590
-.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.

6). PARTS NAME OF STANDARD TOOLING
EACH PART NAME AND FUNCTION OF TOOL
TRUMPFSTYLE TOOLING	1. Alignment Rings • Precision machined and ground for accurate tool alignment. • High impact-resistant steel to maintain superior flatness and durability.
	2. Punches • high speed tool steel for longer tool life. • 1/4º back taper and near polished flanks to reduce friction and eliminate galling. • Minute corner radii on punch point to reduce chipping. • Single point turned radii at base of punch point to reduce stress. • Solid surface contact with alignment ring for superior alignment. • Superior tolerances and surface finishes. • 0.118 (3.00) grind life in 0.250 (6.35) material.
	3. Urethane Strippers • Quiet. • Cushions impact. • Eliminates sheet rattle. • Safe: will not shatter. • Non-Marring even on polished aluminum. • Improved flatter sheets, no puckering. • Positive stripping keeps sheets from moving
	4. Strippers • Keyed to allow 45° angle settings. • High strength tool steel, will not deform or break. Dies • High chrome air hardened tool steel. • 0.059 (1.50) grind life. • Double-cut die opening to improve die strength. • Uniform clearance radii in die corners. • Precision slot orientation-die opening orientation and slot cut in single operation to improve accuracy. • Improved die strength: Domed relief in size 1 and in size 2. • Superior roundness and flatness.
	5. Die Adapters • Permits Size 1 dies to be used in machines with Size 2 die bases. • Precision machined in shock resistant tool steel for greater accuracy, superior machine fit, and longer life.

7). CALCULATION FORMULAS FREQUENTLY USED IN SHEET METAL
TONNAGE CALCULATION In the punch press machine, the allowable tonnage depending on the machine. Use the calculation formula below to prevent from over tonnage.

CALCULATING PRE-HOLE DIMENSION FOR FORMING
When forming processing, pre-holes may be processed as pre-processing. In that case, please calculate pre-holes referring to the following calculation formula

ADVICE ON ONE POINT: Although forming shape is same, pre-hole dimension would be different depending on material. It is recommended that you try trial machining with reference to the above equation to obtain proper pre-hole dimension.
