CNC Turret Punching

Process Overview
The Turret Punching process produces shapes by selectively removing material from sheet metals. These sheets are clamped into the machine on a table that is programmed to move to a specific X/Y location within the matrix of the machine. The correct punch shape and size is selected at the turret and the machine actuates the punch to produce the desired hole. For oblong, rounded rectangles, or other non round or square openings more than one punch may be required to produce the desired opening. The parts created with this process can then be sent for post processes such as bending and forming, welding, powder coating, painting, anodizing, pasivation, silk screening, etc. We perform offline programming and program debugging to facilitate speedy changeovers. This results in faster turn times and helps us to maintain our reputation for on time delivery.

CNC Turret Punching Lead time
Weather you need a few prototypes or several thousand parts, we can meet your requirements quickly using the technology that is best suited for your project. We can provide quick quotations and speedy delivery.

Fast Prototyping Service
Our Fast Sheet Metal Fabrication Prototyping Service guarantees delivery of your parts in days instead of weeks! Delivery time will depend on the drawings and material availability. Post finishing could require additional 24 to 48 hours.
Production Runs
For production runs we typically have a 2-4 week lead time but can begin shipments on a weekly, bi-weekly, or daily basis to suit your needs.
Example parts
Brackets, front panels, enclosures.

Turret Punching Technical Specications
Our typical finished tolerances are +/- .005" (5 mils) positional accuracy, and a +/- .003" (3 mills) repeatability from part to part. Our typical finished tolerances are +/- .005" (5 mils) positional accuracy, and a +/- .003" (3 mills) repeatability from part to part. Please keep in mind that the tighter the tolerances required the more expensive a part may be. For instance a part that has a .002" tolerance may well be 50% more expensive than a part with a .010" tolerance. This scenario may also impact lead times. This should be taken into consideration when designing for manufacturability.
  • Material - most sheet metals used in sheet metal work.
  • Alternative processes - Blanking (for long runs), Laser Cut (for short runs), Mill 3-Axis (for very short runs).
  • Tooling - CNC Turret Punching requires software program tooling and machine tooling setup.
  • Reducing costs - minimize number of different round hole sizes, use stock hole sizes, minimize outside arcs such as rounded corners. Use chamfered instead of round corners. A laser cut part may be lower cost when the design has many curves.
