Colgar metalworking machines

COLGAR

Colgar is the story of a dream. The dream of three young people representing an entire generation, who in 1945, amidst the ruins of the Second World War, courageously and tenaciously decided to start a new adventure. The shared dream of a country that rose from devastation armed only, in the beginning, with passion and honesty, and which over the years has modernized and broadened its objectives in a constant search for all-encompassing wealth. 

This is how a small makeshift workshop became the first factory. The success of the machines and the market's requirements soon led to the broadening, building, and diversification of plants and products. The first simple hand lever cutters soon became electrical, mechanical, and hydraulic shears, followed by the commencement and development of the production of mechanical, hydraulic, synchronized, and automatic press brakes, in a constant drive for technical updating and innovative solutions. 

In the world of sheet metal, Colgar has become synonymous with reliability, strength, precision, and prestige. The boring and milling machines division was created as a technological challenge that also stimulates and enriches the sheet metal working sector. Today, Colgar designs, builds, and develops its machines in three different production units. It controls each phase of the cycle with a certified and established quality system. It presents itself to the market as a reference standard for technological avant-garde and boasts a vast and loyal clientele in the most diverse industrial situations. 

All this increases the value of its origins and the importance of a handshake. We are proud of our history and our consolidated present, certain that our future success will be reflected in the success of our customers.

The dream continues.

The Back Gauge

Precision of Positioning and Repeatability Over Time

We manufacture a range of back gauges that meet different working requirements and guarantee precision of the finished product.

Strength of the Mechanical Frame

Movement of the Axes: Achieved through brushless motors with ball recirculation screws or rack-operated systems, ensuring high precision and positioning speed.

Sideways Movement: Easy and safe sideways movement of the back stops from the machine front for 2-axes back gauges.

Shape of the Back Stops: Designed to suit the operator's requirements.

Working Area: Broad working area with long strokes and a completely free area between the shoulders.

Axes Configurations: Various configurations available, including X-Xn-R-Rn-Z-Zn.

Optional Features: Independent turrets for back gauges for maximum versatility of use.

Special Support Devices: Available for large dimension workpieces.
