Process: Punching

Overview

Punching is a process to cut or create holes in patterns using repeated punches, usually in sheet metals.

Punching makes holes in a piece of material by punching a tool into a die, with the workpiece in between. This creates a
hole in the workpiece. By doing this repeatedly, it is possible to punch holes in patterns. It is also possible to let the
holes overlap each other, making punching an efficient process to cut large pieces of sheet metal.

A modern punch press can hold several tools at the same time. The tools are mounted in the machine tool's turret. The machine tool can be programmed to use them in a sequence, which significantly reduces the machining time. Therefore punching is somtimes referred to as CNC turret punching.

For large volume production, punching can be highly automated. However, it is also possible and cost-effective to punch smaller volumes, especially since the tools are not custom-made for each project.

Punching projects for quote

  1. Drawings count: 2

    Sheet Metal Forming-Punching

    Suppliers with punching capabilities are invited to quote for the production of the attached panel, which is to be made from 8mm thick mild steel. The client seeks quotes for 18 off at this time, for which they are hoping to place an order in the near future. In addition, this will be ongoing work for the chosen supplier. Suppliers who also have in-house rolling capabilities may be seen favourably, although this is not essential.

  2. Drawings count: 1

    Sheet Metal Forming-Punching

    This Qimtek member urgently seeks a supplier who is able to assist with the attached components. Interested parties are required to produce the attached mild steel slotted tubes - the client has suggested the slots be punched, but is open to alternative methods of manufacture. There is an immediate order to place, with ongoing batches to follow shortly.

  3. Drawings count: 6

    Sheet Metal Forming-Punching

    Suppliers with CNC punching capacity are asked to provide a quotation for free-issue lamination sheets, which are required for use within a medical application. The client seeks a second-source supplier for these items, as well as the possible production of similar parts moving forward. They spend a massive £500,000 a year on bespoke fabricated components, meaning that there is plenty of scope for the chosen supplier to develop the relationship. Please note that the overall quality of these parts is paramount.
