# Certified Welding Contractor & Contract Manufacturer since 1963 – Lorch

DIN EN 1090 · EN ISO 3834-2 · 14,000 m² production · 100+ specialists · heavy parts up to 50 t

## Our Milestones

From a village metalworking shop in 1963 to a leading special-machinery business in Baden-Württemberg.

### Foundation

Karl Bock founds a small village metalworking shop with two journeymen at Schulstraße 18 in Lorch.

### Industrial Focus

Continuous expansion of the machinery park for small frames and pre-assembled units in larger dimensions.

### New Generation

40 employees on 6,000 m². Hermann Bock joins the company as a mechanical engineer.

### Expansion

Expansion by 7,800 m² to a total of around 14,000 m² of overall floor space.

### More Milling Capacity

Alongside the Soraluce floor-type mill, the first portal milling machine now joins the machine fleet: the Zayer Thera W 16000. It creates additional room for tall and wide welded structures, and with two large milling machines more orders can be machined in parallel.

### Our Largest Milling Machine

With the Zayer Thera W 26000, the milling envelope grows to 26 m in length, 5 m in width and 3.25 m in height. Together with the smaller Zayer and the Soraluce, we can now mill almost every welded structure we build in-house.

### 100 Employees Strong

Owner-managed company with comprehensive services in special machinery, steel construction and special civil engineering.
Since 1963, Bock Maschinenbau GmbH has manufactured large-scale steel structures and special-machinery components in Lorch (Baden-Württemberg) for customers across Europe. On 14,000 m² of modern production space, more than 100 specialists — welders, machining mechanics and industrial mechanics — work at one of the most capable sites for steel construction and special machinery in Baden-Württemberg.
As a certified welding contractor according to DIN EN 1090 and EN ISO 3834-2, we combine welding, CNC heavy-part machining, shot blasting up to Sa 2.5, industrial coating according to EN ISO 12944, press braking, plate rolling and vibration stress relief under one roof — heavy parts up to 50 t, components up to 26 m in length.
What makes us special: in 63 years, not only know-how has grown but also an exceptionally deep stock of tools and special tooling — from long boring and back-boring bars through angle milling heads and special milling cutters to thread-cutting tools, in-house holders and measuring equipment. This arsenal, amassed over decades, makes us universally capable and able to manufacture even unusual parts — an advantage not every contract manufacturer can offer.
