Ermak CybPress 3100-175

DELEM (Dutch Electronic machine control) is a Dutch control supplier whose DA-series CNC controls are used on press brakes from dozens of manufacturers worldwide — including Amada (DELEM is the basis of their HFE control), Bystronic, and many European OEMs. The DA-66T is DELEM's mid-to-high range 3D CNC with 15-inch touchscreen, 3D bending simulation, automatic tool selection, and multi-stage bend programming. The software and user interface are essentially the same regardless of which press brake brand uses the DELEM control — an operator trained on DELEM DA-66T at an Amada machine will recognize the Ermak's control immediately.

In press brake bending, the ram and bed deflect under bending force — the center of a long bed deflects more than the ends due to the distributed bending load. Without compensation, a 3,100 mm long bend on thick material would produce a part that is straighter in the center and bent more sharply at the ends — inconsistent angle along the length. Crowning applies a controlled upward bow to the press bed (or ram) that exactly cancels the deflection under load, producing a consistent angle along the full bend length. Automatic mechanical crowning adjusts the bed bow based on the programmed material thickness and bending force — critical for quality on long bends.

The CybPress uses European-standard (Promecam/Wila) precision-ground tooling with a European tool holder (flat Wila/Trumpf compatible). Upper punches and lower dies in the European standard are available from all major tooling suppliers worldwide — Wila, Wilson Tool, Mate Precision, Trumpf, and local suppliers. Tool height is the critical specification (typically 100 mm Euro standard) for programming accuracy. The machine's DELEM control has a library of standard tool profiles — custom profiles can be entered for non-standard tools. European-standard tooling compatibility means no proprietary tooling requirement.

Ermak provides a 12-month parts and labor warranty on new machines through authorized distributors. In North America, Ermak has established distributor relationships for sales, service, and parts support. The DELEM control is supported independently by DELEM's service network, and the hydraulic components (Bosch Rexroth or equivalent European hydraulics) are serviced by hydraulic specialists independent of Ermak. For buyers in markets where Ermak has an active distributor, support is comparable to other imported brands. In markets without strong Ermak presence, self-service capability and local hydraulic service expertise are important considerations.

Ermak produces several press brake lines: the standard Optima series (entry-level CNC), the CybPress series (advanced CNC with DELEM DA-66T), and larger capacity machines. The CybPress is Ermak's feature-rich line with the DELEM DA-66T 3D control, automatic crowning, and back gauge systems providing more advanced automation and programming capability than the base Optima. For job shops that need 3D simulation and automatic tool selection, the CybPress's DELEM DA-66T justifies the step up. For simpler, repetitive bending operations, the Optima series provides adequate capability at lower cost.
