Cms Electa 3- or 4-Axis CNC Glass Machining Centre

The CMS Electa is a compact horizontal CNC machining centre developed for processing flat glass, including thin, thick, laminated and bullet-resistant glass.

The machine is available with three interpolated axes or with an optional fourth rotary axis, allowing it to cover a wide range of glass-processing operations within a compact footprint.

In its three-axis configuration, the Electa performs edge grinding, polishing, drilling and milling. The optional four-axis version adds continuous rotary-axis control for cup-wheel polishing, diamond-disc cutting, engraving and chamfering up to approximately 5 degrees.

The machine combines a large working area with an integrated monobloc structure. Retractable access doors, water-recirculation tanks, vacuum pumps and the electrical cabinet are incorporated into or beneath the machine structure to reduce the required factory space.

CMS states that the Electa offers a working area approximately 17% larger than competing machines in its category, while its integrated layout can reduce the required footprint by up to 43%. These comparisons are manufacturer claims and depend on the machines being compared.

Axis speeds of up to 72 m/min support high-speed grinding and reduce non-productive movement between machining operations. Multiple workpieces can also be positioned on the table and processed within the same program.

The working unit uses an 11.5 kW electrospindle with speeds up to 12,000 rpm, an ISO 40 tool connection and torque of 18.5 Nm at 6000 rpm.

The standard three-axis configuration has a 13-position linear tool magazine positioned on the right side of the worktable. The four-axis version adds a second magazine on the left, providing up to 26 tool positions.

The magazines can accommodate grinding wheels, polishing wheels, core drills, milling tools, angular transmissions and other compatible tooling. Multiple grinding and polishing wheels can be stacked on the same holder where the complete tool pack remains within the permitted dimensions.

A crosshair laser fitted to the operating unit helps the operator position the suction cups quickly and accurately.

The optional automatic dressing system can dress grinding wheels and core drills at programmed intervals, helping maintain cutting performance and reduce manual intervention.

The four-axis Electa can also be equipped with a dedicated engraving system for producing decorative features, markings and patterns on glass and mirrors.

The integrated 21.5-inch touchscreen uses the CMS Active interface and guides the operator through machine setup, tool management and production.

EasyGlass CAD/CAM software manages CNC programming, geometric drawing, tool selection, suction-cup positioning, machining simulation and production-time calculation.

Optional software functions include laser projection of suction-cup positions or toolpaths, automatic polishing-pressure management and template acquisition using a probe.

The CMS Electa is suitable for glass doors, shower enclosures, staircases, façades, windows, mirrors, tables, oven doors, hob tops, safety glass and bullet-resistant glass.

Stone & Glass Group supplies the CMS Electa throughout the UK, Ireland and the Benelux, supported by application advice, installation, commissioning, operator training, tooling, spare parts and technical service.
