Product Name: Universal Milling Machine M57 Series
Performance:
· Universal milling machines with digital display is a newly developed products based on
traditional knee-type milling machine and has more advanced features than the general one;
· Infinitely variable feed speeds controlled through powerful motor;
· Rapid feed on 3 axes;
· Hardened and ground gears, nitride hardened in oil-bath;
· Pre-loaded ball screws, with backlash free preloading,which ensure easy, precise feed during
manual and motorized operation;
· All operating controls in duplicate, machine can be operated from the front or from the left side;
· Universal swivel head, milling head can be turned in any special angle;
· Enlarged machining capacity, widened spindle speed range, infinitely speed changing, two sets
operating handles for easy operation, interlock between locking and power/manual feed system,
automatic lubrication system, sufficient rigidity and so on;
· This machine can mill plane, groove in cavity of some workpiece. being installed with various kinds
of borers, it can bore different holes vertically, horizontally, left-horizontally or right-horizontally;
· Equipped with special-purpose tooling, it can bore inclined hole with special angle. it is suitable for
metal-working operation of all kinds of factories, especially for die and mould.
· Digital position indicator as optional choice;
· The model of machines with A have servo motor and axis control on all 3 axes.
Standard Acessories:
· Universal swivel head;
· Operating tools;
· Automatic central lubrication;
· Coolant system;
