Automec CNC 150 vs. CNC 300 vs. CNC 600

The Automec CNC 150, CNC 300, and CNC 600 all program press-brake backgauge positions, but differ in stored-job capacity, bend-program features, and operator interface; a controller-only retrofit fits only when the existing gauge and brake support the selected configuration.

The AUTOMEC CNC BACKGAUGE CONTROL SYSTEMS family moves a motorized rear backgauge through programmed positions for successive bends. That automates gauge positioning, not sheet handling or the full press-brake cycle: operators still position and reorient stock, install tooling, and operate the press.

Compare the controller functions

The CNC 150 stores 150 jobs with up to 20 bends per job. Its one-, two-, or three-axis configurations can be set up for backgauge positioning, ram control, and programmable gauge-bar height. It is a candidate when that job capacity and the required configured movements match the work.

The CNC 300 stores 300 jobs, with 10 bends per job and job linking available. Its documented functions include depth or angle mode, angle correction, and top-of-stroke reference. Those features matter when the application calls for the corresponding ram-control functions; they do not establish that an existing press brake supports them.

The CNC 600 provides virtually unlimited job memory with up to 20 bends per job, USB job transfer and storage, photo import, and programmable delay or retract between bends. Its touchscreen and job-transfer features may suit an operator workflow that uses stored programs and visual references. Job memory does not increase the documented bends per job, and a feature list does not establish retrofit compatibility.

Match the model to the jobs

Compare representative jobs by the number of stored programs and bends, whether linking is useful, which axes the work actually requires, and how operators need to view or transfer jobs. For Illinois and Indiana fabricators, this makes the choice a production-workflow decision rather than a comparison of controller names alone. Do not assume that a larger job-memory figure, display, or axis option will improve a process that does not use it.

Confirm the existing gauge before a control-only upgrade

The published Automec control-upgrade path names existing G24, CNC99, CNC1000, and CNC2000 systems with mechanical structures in good working condition; the backgauge serial number is needed to configure the control. That information is not proof of compatibility for every press brake or another manufacturer’s gauge. Identify the brake, current control, backgauge model and serial number, axis arrangement, and the functions required before settling the scope.

A controller does not repair worn gauge mechanics or resolve a separate machine-condition problem. If gauge movement or test bends are inconsistent, distinguish the control question from mechanical, hydraulic, ram, or other brake concerns. A backgauge control also does not establish that safeguarding is adequate. OSHA’s machine-guarding requirements address point-of-operation hazards separately, so evaluate safeguarding independently, particularly if the proposed work affects guards, safety devices, or operator controls.

I’m Adam Quoss, Mac-Tech’s Vice President of Sales, serving Illinois and Indiana. I can help frame whether the work calls for backgauge positioning, additional configured functions, or a broader equipment decision. Bring the brake and current-control identification, backgauge model and serial number, axis arrangement, and a representative part drawing or bend sequence, along with the positioning or machine issue you want to address; I can help assess the control scope and next equipment discussion.
