Definition: Horizontal Boring Mills

Horizontal boring mills are considered as special machines for small to medium-sized workpieces processing. Spindle diameter, machine weight, table carrying capacity and work surface are smaller-dimensioned in compact horizontal boring machines than in floor type boring mills. A boring machine with a horizontal design is characterized in fact by a table, movable on X/Y axis, while the main spindle is mounted on the stationary machine base. Modern horizontal boring mills from leading manufacturers such as SCHARMANN, UNION (BFT) or WMW distinguish themselves by the efficient CNC controlling systems, like HEIDENHAIN. At Surplex you will find used boring machines with the appropriate technical data (spindle rotation speed, total power requirement, etc.).

Used for the general building of machines

Generally, the horizontal boring mill is commonly used for the building of machines. Characteristically, the drilling and milling work can be done on a horizontally clamped in workpiece. A movable column is used to carry the spindle headstock with the workpiece receptacle. Operation and feeding is done over the spindle headstock. The workpiece receptacle can host a whole row of cutting tools including drills, drilling rod, milling shafts and turning tools.

  • Can hold several tools for boring
  • Used for producing casings and tools

Therefore, the tool holder is standardised and generally equipped with a morse taper. Horizontal boring mills now also have the possibility to switch tools using CNC technology. The machining table (clamping table) contains the possibility to clamp in the workpiece using clamping screws or other apparatuses. The open construction allows for very large workpeices to be processed. These machines can be up to 10 metres high and contain a large mounting surface. The machine casing is very robust and, like the column, can be used to host the spindle stock. The mounting table can be adjusted with the different axles and have a fixed position. Nowadays, most machines are CNC-operated and this ensures efficient operation.

History, development and background of the horizontal boring mill

The development of the boring mill revolved mainly around the growing number of tasks it could undertake and its developments in machine building. The boring mill was first developed and produced in Germany in 1875. The machine tool factory UNION was very important in the development of the modern horizontal boring mill. Nowadays, UNION builds horizontal boring mills with drilling spindles that have a diameter of up to 250mm. This feature travels along the x-axis (40m) and the y-axis (10m). Thereby, the workpiece weight can be up to 250tonnes. The machine is CNC-controlled and provided by well-known suppliers, such as SIEMENS.

Areas of applications and examples of these machine tools

General machine building is the main area of application for these large machines. This includes various branches like casings for gearboxes or the building of tools. It can be universally implemented, as there are a variety of different work stages that can be undertaken by the horizontal boring mill in every type of industrial production. The precise positioning is a criterion, which is important for the building of cutting and punching tools. Even moulding requires boring mills for the exactly positioning and processing of guide pillars and ejector pin holes.

Well-known manufacturers of horizontal boring mills

Several companies have specialised in the manufacturing of horizontal boring mills. Some of the most recommended suppliers include UNION, SCHARMANN, GIDDINGS + LEWIS, DAEWOO, SACEM. You can regularly find used machines in good condition in our numerous industrial auctions.
