VSC series

Machining center spindle cooling

Non-flon-gas oil chiller VSC-N Series are used to cool the spindles and headstocks that greatly affect machine center accuracy. By controlling hot gas bypass with a heating valve, the VAC-N Series adjusts cooling capacity according to the heat generated by the object it is cooling, thus making it possible to control accuratelly within ±0.1℃, a degree of precision difficult for older standardized oil chillers to achieve. Non-flon-gas oil chiller VSC-N Series can also be safely used for machining equipment spindle cooling, which requires a high degree of precision.

Broaching machine hydraulic oil cooling

A customer installed non-flon-gas oil chiller VSC-N Series together with new broaching machines. Hydraulic oil used to power the hydraulic unit becomes hot when the machine is in operation, and if the oil is not enough cooled, various problems can occur, such as actuator oil leaks and oil leaks from packing members. Controlling hydraulic oil with the oil chiller eliminates these problems and contributes to stable equipment operation.

6-spindle milling machine hydraulic oil cooling

A customer was having equipment shutdowns and other problems due to rising hydraulic oil temperature in their 6-spindle milling machine. As the solution, the customer installed a non-flon-gas oil chiller VSC-N Series. Given the recent global effort to reduce greenhouse gases, and in order to comply with fluorocarbon regulations, when installing new cooling equipment, more and more customers are adopting equipment that uses nonflon cooling.

Machining center spindle cooling

Customers install non-flon-gas oil chiller VSC-N Series to cool machine center spindles. When a worn out existing oil chiller breaks down, customers are steadily replacing them with nonflon oil chillers in order to comply with recent chlorofluorocarbon control standards. Customers are impressed by how non-flon-gas oil chiller VSC-N Series reduce chlorofluorocarbon-related cost and labor and do not incur chlorofluorocarbon collection and disposal costs when discarding equipment.

Broaching machine hydraulic oil cooling

Customers install VSC-N Series non-flon-gas oil chillers when replacing worn out oil chillers. The Revised Chlorofluorocarbon Control Law requires that chlorofluorocarbon equipment be inspected once every three months. This greatly increases the burden of this equipment for users who have several cooling devices, but nonflon oil chillers do not need to be inspected and enable the user to focus on their regular work.

Press machine hydraulic oil cooling

Customers use non-flon-gas oil chiller VSC-N Series to cool hydraulic oil in press machines. There are other methods to cool hydraulic oil besides oil chillers—water-cooled heat exchangers and air-cooled heat exchangers, for example—but these methods have difficulty keeping settings stable at the preferred temperature due to fluctuations in water and air temperature. In this case, the customer selected an oil chiller capable of forced cooling and keeping oil temperature constant.
