MACH Machine Tools has supplied Sanoh UK Manufacturing, a tier-one supplier and manufacturer and distributor of tubular products to the UK automotive sector, with a new vertical machining centre. The machine, a three-axis MACH MDV 1160S equipped with the DynaPath control, arrived at the company’s Engineering Centre facility in Avonmouth in April 2025. It replaced two older semi-automatic milling machines that were part-exchanged to help fund the investment.

Since installation, the MACH MDV 1160S has been put through its paces machining a range of different-sized base plates for gauges and assembly fixtures. The plates are made from aluminium and measure 12.7 mm thick. Machining operations comprise the drilling of pre-fixing holes on the underside, allowing secure clamping on the machine table, before the drilling of application-specific holes on the top side that serve to hold a number of posts and blocks in position.

Says Leyton Dunn, Engineering Centre manager: “Prior to investing in the new MACH machine, these drilling operations were performed on our semi-automatic mills. However, the relatively small worktables meant that we were constantly having to stop drilling to unclamp the plates, move them to a different position and re-clamp.”

On a recent project involving the drilling of a series of holes in 10 different sized plates, the size of the worktable on the MDV 1160S meant the number of plate movements and the related re-fixturing operations required was reduced to just four instead of 24. Moreover, the project was completed in 70 hours less than if it was handled on the Engineering Centre’s semi-automatic machines.

German vertical machining centre manufacturer Roeders, whose machines are sold into the UK and Irish markets exclusively by Hurco Europe, is rolling out a new range of milling platforms. The machine feature optional integral grinding capability that can achieve extraordinarily tight workpiece tolerances.

The RPT series of three- and three-axis VMCs is said to achieve tolerances half those obtainable using Roeders’ established RXP machines. Roeders’ latest VMCs can remain geometrically stable to within ±1 µm, even if the ambient temperature fluctuates as much as 3°C.

Achieving this level of precision would normally require housing the machine tool in an air conditioned environment. Roeders concentrated instead on holistic temperature management within the machine, integrating PreciTemp technology to achieve a high level of consistency and repeatability.

Customers can specify three increasingly sophisticated levels of temperature compensation and sensor feedback to the CNC, according to requirements. It can involve a combination of some or all of the following cooling measures: temperature control of the machine table and rotary axis bearings; temperature control of the torque motors in the trunnion-type five-axis machines; and temperature control of the air in the working area, surrounding the axis drives and in upper part of the machine guarding.

Thermal stability of the portal structure and machine bed is maintained by embedded pipework carrying chilled water. There is similar circuitry for the spindle and its surrounding sleeve to prevent growth in the Z axis, which is monitored to sub-micron accuracy by an external, non-contact sensor. Software algorithms derived in the course of machine development compensate for any remaining minimal residual errors.
