A brand new open-center pneumatic cylinder was developed by JATO Precision for the high speed and high accuracy CNC lathes which use spring collets to clamp work-parts. JATO JAL636-PL pneumatic cylinder has extremely low temperature rising to avoid thermal error of spindle system of CNC lathes, and it also largely decreases building cost of the machine since no hydraulic pump, tank and cooler is needed.
Today, more and more industrial parts are smaller in size and are required to be more accurate in dimension than they were in the past. Many machine builders find hydraulic cylinders which are being used most commonly in the industry today as actuator of power chuck or spring collets have an unsolvable problem - temperature rising. For instance, the surface temperature of a regular hydraulic cylinder may reach
JAL636-PL is powered by compressed air, meaning that the building cost of machines can be lowered by saving the purchase of a hydraulic tank and a hydraulic pump. The experiment shows the temperature rising of the cylinder body is less than 8 digresses Celsius when running at 6500RPM; this can further lower the cost since no cooler is needed. JAL636-PL comes with compact size and low mass, 162mm (
JAL636-PL is the first product of JAL series pneumatic cylinder. There are several machine builders have already phased-in this brand new product on their lathes. JATO also is rewarded by Taiwan Industrial Development Bureau for the excellent design of this high performance pneumatic cylinder. To further strengthen our pneumatic cylinder product line, there are two new products which will be released at the Q4 of 2008. JAL846-D is design to provide very large clamping force with its double pistons, suitable for actuating
