Finishing and end f inishing

Belt grinding of heavy bars and tubes from India

over from one job size to another. Tubes/bars from 60mm to 300mm diameter can be ground.

The floating belt grinding heads operating from the top are specially designed to take care of bend and ovality in tubes. These heads are mounted on a long trolley, which is rigid in construction. The machine has very easy settings to ensure quick change

GRIND Master offers a trolley-type machine for belt grinding and finishing of large diameter and heavy bars and tubes. The machine has heavy-duty roller supports to take up the tube/bar to be ground. It also provides the rotational drive to the job being ground.

Twin cutting and workpiece finishing from Rattunde RATTUNDE Corporation, a

of every part produced for full part traceability, material lead and end edge detection for minimised crop cut and tag end. All operating limits are set from the control panel, with continuous tool break monitoring for the saw blade and all cutting tools. Even when processing in twin mode, the set-up time for a new job can be under 15 minutes, according to Rattunde engineering. Because the machine offers essentially double the production in the same machine footprint, up to 40 per cent energy savings have been documented on a 25mm OD x 3mm wall x 42mm long piece from a stock length of 6m in a typical batch count of 45,000.

based on carbon steel. When the twin head is removed, the standard machining head can process a single workpiece up to 105mm OD. In addition to the twin workpiece processing, the new Rattunde machine offers the OEM or production house all the capabilities found on Rattunde’s ACS family of tube and bar production systems, including secondary brush de- burring, end machining (chamfering and facing), inspection, washing, drying and robotic packaging. The entire machine and all auxiliary workstations are motion-controlled by CNC from a single operator station for maximum efficiency. The ACS + CFMtwin is built on the same platform as the existing Rattunde ACS + CFM and ACS + CFMcurve systems. Other standard features on the new machine include data management on all workpiece parameters (approximately 10,000 workpieces), data logging

manufacturer of finished length tube and solid bar production, has introduced the ACS ® + CFMtwin machine, the latest in the company’s range of tube production systems. Equipped with a specially designed twin machining head that fits onto the standard head, the new machine can cut two tube or bar sections simultaneously, and then machine both ends of both workpieces, also simultaneously. The new machine can produce up to 5,000 finished pieces per hour, and the option also exists for single tube or bar production on the same machine. The ACS + CFMtwin machine, when in twin mode, can process two workpieces of 10 to 41.5mm OD each into finished lengths from 10 to 1,500mm. As an example: 21mm OD x 3.5mm wall x 45mm length cut from a 6.5m mill length of stock material,

Each end of the two workpieces is simultaneously chamfered before automated transfer to the cleaning and final packaging stations
