What is fine blanking press?
Fine blanking presses are used to process thin materials such as sheet metal, plastic sheets, cardboard, wood or even paper. The finest contours can be punched with a consistent precision, using this high-precision technology. Fine blanking presses are also called “fine cutting” presses.
What is fine blanking used for?
Fine blanking makes use of additional supporting tools (pads) and impingement technology to minimize plastic deformation during the shearing process. Fine-blanked gears are used in automotive parts, appliances, office, and medical equipment .
Which are the components that can be processed using fine blanking?
Fine Blanking technology has created niche requirements in the automobile industry for the production of high precision parts for engines, transmission ports, breaking systems, door latches, window lifters, gearboxes etc.
What is major advantage of fine blanking over conventional blanking?
Fine blanking enables the production of high-precision parts whose cut surfaces do not have to be reworked. Fineblanking, which was developed in Switzerland in the 1950s, added a slower but very precise stamping process that provides all cut surfaces with a smooth cut that meets the highest demands.
What is blanking in sheet metal?
Blanking is a metal production process, during which a metal workpiece is removed from the primary metal strip or sheet when it is punched. The material that is removed is the new metal workpiece or blank.
What is the blanking process?
What type of press is required for a fine blanking operation?
metal stamping press
Fine blanking uses a specialized metal stamping press that provides equal pressure from both top and bottom on the metal sheet to produce flat edges by cutting the periphery in one stroke.
What is the difference between blanking and fine blanking?
In blanking we have to divide two different types: open and closed contours. It can be assumed in blanking (stamping) operations that around one third of the cut metal thickness is a clear-cut surface and the rest a breaking surface. In fineblanking, a 100 % smooth cut is desirable (target).
What are the blanking process?
Blanking is a metal fabricating process, during which a metal workpiece is removed from the primary metal strip or sheet when it is punched. The material that is removed is the new metal workpiece or blank.
What is difference between punching and blanking?
If you punch a hole out of a piece of paper and keep the circular piece, then you have blanked the paper. If you keep the sheet of paper and throw away the punched-out piece, then you have punched the paper.
What is blanking machine?
Simply expressed, blanking is the process of shearing from sheet or strip metal a blank of a given shape. The term normally implies two things: (i) To the process is carried out under some type of press, and. (ii) To the entire edge of the resultant blank has been subjected to a shearing operation.
What is blanking in a video signal?
In television, “blanking” means going to black. As part of the video signal, blanking voltage is at the black level. Video voltage at the black level cuts off beam current in the picture tube to blank out light from the screen. The purpose of the blanking pulses is to make invisible the re-traces required in scanning.
How big is an Amtech fine blanking press?

What are the three types of Fine blanking?
The fine blanking machine is special equipment for realizing the fine blanking process. As shown in below figure, there are three kinds of forces (P S, P R, P G) acting on the die during fine blanking.
Which is the best company for fine blanking?
As a result, fine blanking can be a cost-effective option in many cases. AmTech International is a TS16949, ISO9001 and QS9000 certified company offering stamping and fine blanking solutions for OEM and automotive companies in North America.
What are the different types of metal stamping presses?
The three common types of stamping presses include mechanical, hydraulic, and mechanical servo technologies. Usually, presses are linked to an automatic feeder that sends sheet metal through the press either in coil or blank form.
