CNC Punching Process Offers Unlimited Holes & Shapes Accurately And Quickly

CNC punching is a metal manufacturing process, refers to the technology that uses computer controlled punching machine to punch out of target patterns on the plates. There are many materials can be stamped by CNC machine tools, such as stainless steel, galvanized steel, aluminum, copper and plastic. The automation and repeatability of CNC stamping makes the punching process both accurate and fast, while producing less waste. Our commonly used CNC punching machines include ordinary CNC punch machines, gantry punch machines and turret punch machines. We are very happy to introduce for you.

Ordinary CNC Punch Machine

CNC program is a set of instructions, using computer numerical control drive punch to construct a variety of shapes, generally speaking, ordinary CNC punch machine can punch some circular, square and other simple shapes, such as perforated metal sheet perforated metal tube, corrugated perforated metal panel are processed by ordinary CNC punch machine.

Advantages:

Low machine cost.
Production efficiency is greater than manual machines.
Simple operation, low difficulty.

Disadvantages:

Only applicable to simple punching shapes

High Speed Gantry Punch Machine

High-speed gantry punch machine is made of integrated special cast iron alloy, which can meet the needs of any automatic production. It is suitable for processing large number of round holes with fixed plate width. It is often used for perforated rolling plate and corrugated perforated metal panels.

Advantages:

Fast production and processing efficiency can generate huge economic benefits.
Low processing labor intensity.
High machining accuracy.
Can process complex parts.

Disadvantages:

Machines cost expensive.
Suitable for thin plate thickness.

CNC gantry punch machine is perforating the coil plate.

CNC Turret Punch Machine（NCT）

CNC turret punch machine is one of the main categories of CNC punch machines, integrating machine, electricity, fluid and gas. It is a pressure processing equipment for punching and shallow drawing and deep forming on the plate through the turret punch die. Decorative perforated plates and safety grating commonly use this process.

CNC turret punch machine is punching the metal plate.

Advantages

Strong adaptability to parts, can process complex shapes of parts surface.
High machining precision, stable machining quality.
Shorten production preparation time and promote modern management.
High productivity, compared with ordinary machine tools, CNC turret punch can improve production efficiency 3–5 times.
One machine multi-purpose, reduce labor intensity, save plant area.

Disadvantages

The equipment is expensive and the initial investment of the equipment is high.
The integration of mechanical, electrical, hydraulic and computer technologies has high technical requirements for users and maintenance personnel.
Manual programming is a heavy workload when machining complex shape parts.
