Castings
Main bodies of the machine are made of high rigid resin sand castings with thermal / vibratory stress relief
(VSR) aging treatment. Steel parts are thermal refined.
1. resin sand casting,
2. high grade, high intensity and low stress
3. stress relieved castings to absorb the stresses and dampen the vibration during cutting
Machine structure
4. Thermo-symmetrical gantry frame structure
The machine adopts a stable thermo-symmetrical gantry frame structure and consists mainly of base,
table, R.H. and L.H. columns, cross rail, top beam, tool heads, hydraulic system and electric system.
Columns and cross rail are of box-shaped castings with numerous reinforced ribs. Two columns are
connected through the top beam on the top and bolted to the base at the bottom so to form a superb rigid and stable structure that is qualified for stable and heavy cutting even at severe cutting conditions.
Layout of components of Double Column Vertical Turn Milling lathesOne DC 55 kW main motor and a speed change gearbox are fitted at the back of machine to drive the table. Cross rail moves up and down along front guideways of columns. The two tool heads are seated on the guideways of cross rail. The tool heads are composed of carriage and ram. Rams are induction
hardened and precision ground and jib strips are made of wear-resistant industrial alloy material and
hand scraped for precision matching. Compulsary lubrication systems are used in main drive system and on sliding guideways. Independent hydraulic power pack locates behind the machine for easier adjustment and maintenance. Independent electric cabinet is equipped for easier venting of heat and easier check

Adavantage:

Our company adopts the international advanced resin sand casting process. The castings are made of HT300 and HT250 and then tempered twice. The castings are tempered once before processing. The castings are subjected to secondary tempering after rough machining. The tempering is tempered to the greatest extent in the tempering kiln. Reduce the internal stress of the casting, and perform vibration aging before finishing to prevent the casting from deforming, thereby improving the accuracy of the machine tool.

Parameter can be customized

The vertical lathe has C axis for milling, drilling, boring, tapping
