CNC Turret Punching · Miami Gardens, Florida

CNC Punching Services

Our Amada AE 2610NT CNC turret punch produces holes, louvers, embosses, extrusions, lances and knockouts in a single setup, backed by a library of 794 standard and special tools. For parts with many repeated features or formed details, punching beats laser cutting on cost.

Overview

When a Turret Punch Is the Right Tool

A laser cuts any shape but only cuts. A turret punch also forms. Louvers, countersinks, embosses, extruded holes for tapping, card guides and electrical knockouts are made in the flat on the punch, in the same hit sequence as the holes, with no second operation. On perforated panels and parts with hundreds of identical holes, the punch is also faster.

We run both processes side by side, with five Amada lasers next to the turret, so each part goes to whichever is cheaper and better for it. Often that is a combination. See laser cutting vs CNC punching.

Features

Features We Punch and Form

Hole Patterns and Perforations

Round, square, rectangular, obround and special-shape holes; vent patterns and perforated panels.

Louvers

Ventilation louvers formed in the flat with consistent height and spacing.

Embosses and Dimples

Stiffening embosses, offsets, standoff dimples and countersink forms for flush screws.

Extrusions

Extruded holes that give thin sheet enough thread depth to be tapped.

Lances and Bridges

Card guides, cable tie bridges, tabs and locating features.

Knockouts

Electrical knockouts for enclosures and junction boxes.

If your drawing calls for a shape that is not in our tool library, send it. Special tools can be ordered when the volume justifies it, or we will cut the feature on a laser.

Design Notes

Designing Parts for Punching

Use tools we already own. Matching your hole sizes, louvers and knockouts to the tool library avoids tooling cost and lead time.
Keep holes at least one material thickness in diameter, and keep features away from edges and bends so they do not distort.
Formed features have a direction. Show which side louvers and embosses face, and leave room for the tool body around them.
Tell us the annual volume. It decides whether punching, laser cutting or a mix gives the lowest piece price.

See the DFM guide and tolerances.

After Punching

Punched Parts, Finished

Punched blanks move straight to deburring on three Timesavers wet machines, then forming on nine Amada press brakes, hardware insertion, welding, finishing and inspection. Flat parts are checked on our Amada Fabri-Vision optical inspection system against the CAD file.

Straight Talk

Where Punching Does Not Win

Thick plate, complex outside contours, very small quantities with no repeated features, and cosmetic edges with no nibble marks are laser jobs. Material over 1/4 in. does not go on the turret at all.

You do not have to decide. Send the part and we will quote the process that makes it best.

FAQ

CNC Punching Questions

What CNC punching equipment does MJM have?

MJM operates an Amada AE 2610NT CNC turret punch press with a library of 794 standard and special tools, at its Miami Gardens, Florida facility.

How thick can MJM punch?

Up to 0.250 in. (1/4 in.) in mild steel and aluminum, at a typical tolerance of ±0.005 in.

Is CNC punching cheaper than laser cutting?

For parts with many repeated holes, perforations or formed features such as louvers and embosses, punching is usually cheaper and faster. For complex contours, thick material and low quantities, laser cutting is usually better. MJM runs both and quotes the most economical route.

Can MJM punch louvers and knockouts?

Yes. Louvers, electrical knockouts, embosses, extrusions, lances and countersink forms are made on the turret punch in the same setup as the holes.

Can I see which punch tools MJM has?

Yes. The full tool library, with sizes, shapes and drawings, is published at mjmmfg.com/tools/.

What materials can be punched?

Mild steel, stainless steel, aluminum, galvanized and galvanneal steel, copper, brass, titanium, polycarbonate and other non-metallic sheet materials.

Working with MJM Manufacturing has been one of the best vendor experiences I've had. The parts matched my samples perfectly, and even the packing was done with real care — clean, organized, and professional. Of all the vendors I've worked with, they're by far the most organized and quality-focused. Great communication from start to finish. Highly recommend them for custom fabrication work.

As a customer, I have been working with MJM Manufacturing for approximately 35 years. The expertise of Mike Mijares and his team at MJM is top notch. Whenever I have a new part design, I typically review the design of the part with MJM to ensure that I am using the most cost-efficient manufacturing process to produce the parts as economically as possible. There was a part that we had made years ago using a progressive die to emboss a curved channel into a sheet metal part. The cost of the progressive die for this part was $55K. The redesign of the part from MJM consisted of $1200 in tooling to make the new part profile. Parts came out great and saved tens of thousands in tooling. Lastly, whether MJM produces a prototype or a production run, the appearance of the part is pristine, no tool marks or scratches on any part. In the 35 years that I have worked with Mike and his team, I have found them to be one big family. Mike’s love for his business is refreshing! You rarely see a person that is so charged to get up for work every day! Richard Havass Mechanical Engineering Manager JCI-Sensormatic
