PTJK21 Series C Type High Speed Press
	Purpose and structure performance With AutoCAD, the designation of PTJK21 series presses are fully considering the dynamic precision at high speed, bottom dead center changing, vibration and noise, which makes sure of high quality products at high speed. The efficiency of PTJK21 series presses is 3-5 times of normal presses. The punched accessories has high precision, the die has long service life, while the press will also save human resource and material. This series presses are appropriate for precision punching and silicon, steel plate, chain, disc spring etc. It is widely used in the fields as electric motor, low voltage apparatus, instrument, light industry. The press is especially used for middle steel plate punching. ◆ Welded frame with quality steel which means good rigidity ◆ Square figure and long guide with six friction-faces makes sure of abrasion resistant and stable ◆ Hydraulic overloading protector can give die more accurate and quick protection. And the pres ◆ Fixed with friction clutch and brake, closed bevel gear with dipped lube. Slide with counter ◆ Intermittent auto lubrication makes every point get fine and safe lubrication. Long service life. ◆ PLC controller makes sure of sensitive motion and reliable performance ◆ Speed die changing, air cushion, photo guard, auto feeder are optional ◆ Infinitely variable speed device is used for adjusting speed ◆ The frame of A type is strengthening semi-closed structure. The bearings of main shaft. ◆ A type press is more rigid, faster with high precision than standard products.
