Siemens Partner, Trend Machinery, Retrofits Grinder At Sandusky International

As Bob Gordon, president of Trend Machinery, said, "The machine was sent to us, as it was not difficult to transport for evaluation. We determined what the equipment needed, including a Siemens 810D CNC to replace the original control, as well as 611U drives and 1FT6 motors, also from Siemens. An entirely new control console and enclosure were customized for Sandusky. We also replaced all the electronic hardware such as starters and relays." Additionally, all limit switches were replaced, motor mounts were modified and the grinding spindle was repaired.

The machine was returned to Sandusky with full electrical schematics, bill of material and program files. Also, the Normac grinder was cleaned and completely repainted to customer specification. Trend supplied a one-year warranty on all parts, backed by the primary component supplier, Siemens.

Satisfaction with the job has been confirmed by Sandusky Machining Technician Ron Gearhart: "The work was done on time, in a professional manner and at the price quoted. This was an excellent investment for our company, as the

Normac grinder before retrofit. The original control was no longer holding proper positioning, plus parts and service were unavailable to the user, Sandusky International.
Following the retrofit by Trend, in which a new Siemens CNC, motors and drives, plus most electrical hardware, were replaced. A Sandusky technician said  the machine is running as good as new, perhaps better, owing to the enhanced control features now onboard.

machine has been performing beyond our expectations. This is due in part to the enhanced features on the new CNC." He further cited the thorough documentation supplied, the neat appearance of the controls and organization of the electrical panels as further evidence of a job well done.

Trend Machinery was founded in 1976 and is owned by John and Robert Gordon. The firm designs and builds custom machines, with a particular expertise in grinders. Trend also performs CNC retrofits to update obsolete controls, as well as motion control systems integration and turnkey machine conversions from manual to programmable operation.
