Mechanical Advantage - Main Machine

Castings of VMC machining center are made by advanced Meehanite casting iron. Such kind of material is very stable and can make sure there is no distortion after long-term using. Grade of casting is GC -275. We adopted integrated forming technology, box structure, plus our large 5 axis machining center machine to finish processing of them by just once fixing, this characteristic makes sure good rigidity, high intensity excellent geometrical precision of VMC machines. At the same time it promises long term stability and accuracy. Other companies choose normal casting and steel plates welding method to produce machine bed parts; these machines are bad in performance, easy to happen resonance, easy to break down, short life, can’t do heavy cutting work, will lead to great loss.

Use of Mechanite Cast Iron GC40 (GC275)

Mechanite cast iron GC40 is suitable for casting with thickness 10-15mm. This kind casting is good in compact structure, good intensity, suitable hardness, low coefficient of friction, it has feature of self-lubricating, after quenching treatment, and it is widely used as workpiece which have friction of its surface, such as machine tools bed, seat, working table, and cylinder, and so on.

Mechanical Advantage -“A” Structure Column

“A” structure is adopted as column to support spindle box and its movement in Z axis direction, Using such design can improve rigidity and cutting stability of machining remarkably, with this design, our machine is suitable for heavy cutting and large table load.

Mechanical Advantage - unique tool changing structure

• A: Special material as this structure, processed by precious machining and unique heat treatment, accelerates changing tools; this design is much accurate (no impaction to spindle) and smooth without noise.
• B: We adopt particular, stable air pressure driving oil as method of spindle loosing tools, double-action, it is much excellent in speed and stability of than just using air pressure or oil driving.
• C: Large capacity tool magazine with 24 tools, advanced cam type tools changing system is equipped, random memory of magazine management, which much faster and stable in changing tools. (Optional)

Mechanical Advantage - Optimized Structure of Y Heavy Rail Linear Guide

Roller guide (Standard)or ball screw guide (Optional) for X,Y,Z axis of Baoma machines, which  is provided by worldwide well know enterprises. Comparing with ball screw guide, leading and damping properties of roller guide has been improved 30% and 15% respectively, comparing with steel guide, dynamic motion function has been improved 300%, at the same condition, machining efficiency will be 2-15% better, lift of machine will be 3-6 times longer, so no need to break machine own to repair, it will save production cost.

Mechanical Advantage - Adopt Three Slide Blocks for Spindle Axes

Adopting three slide blocks for single axis will enhance load capacity around 30% ,with this method the load capacity and the rigidity will be improved.
