Product Details

●　PGT PF series is a high quality profile&surface grinding machine integrated high precision and high stability. The function and control system of PF series is designed with rich grinding experience to close Chinese customer’srequirement.

●　Recirculating ball screw in Y axis and absolute linear scale 0.0001mm measuring system makes batch, mass prod-uction easier and efficient.

●　PGT Easygrind manual control system develops traditional manual machines to maximum advantage, makes sin-gle, batch production easier and efficient.

●　Multiple optional function and accessories meet different customer’s actual grinding requirement, automatic grinding cycle, end face grinding, profile&surface grinding and multiple dressing untis, etc.

●　The combination of PF control system and human-machine can realize manual and automatic switch at will during the machining process, which makes high-precision grinding simple and fast;

●　The left and right high-speed reciprocating function can be selected (models below 630);

●　The standard left and right sides are driven by hydraulic servo, which makes the operation more stable and the acceleration and deceleration response faster.
