Jeffer JF-330 Profile Grinder is the most important grinding machine for the plywood factory. It grinds on the basis of the shape of template, then follow characteristic of profiling machine to grind various irregular profiles of knife tools.

With 1 to 1 template, before processing knife tools, the electronic operation panel locates the shape of template, when it is finished, it starts grinding. This profiling machine grinds knife tools in manual, because it operates by working table with linear bearing cross roller rail set, it can be easier and more stable to enhance grinding accuracy. One's more, knife grinding angle is varied by micro-adjustment for wheel head angle and it keeps its central to get higher precision and fluent in operation.

Moreover, JF-330 Profile Grinder changes its speed by inverter to make the speed of grinding wheel faster, even reach 6000R.P.M under special specification. With high-speed rotating and CBN wheel, after using coarse wheel and fine wheel that the knife tools’ profile can be smooth and sleek. On the other hand, JF-330 grinding wheel owns 3HP motor that it gets stronger power and higher efficiency. Faster grinding wheel speed and continuous various speed can grind HSS knife head by normal grinding wheel, you may also adjust work status by yourself.

In order to arise convenience of operation, Profile grinder equips quick-release flange that can exchange grinding wheel quickly and correctly to let your operation more convenience. Furthermore, in a high stable linear bearing cross roller rail sets, it decreases the difficulty of manual operation. JF-330 combines the characteristic of profile grinder and quick-release grinding wheel flange to let you attain an easy and rapid operation.
