Lead Machine Tools recently installed yet another Sino VMC1000P Vertical Machining Center in Cape Town. The VMC1000P has been a top seller for WD Hearn the past few years and features an 8000rpm spindle and 1200x520mm Worktable. The combination of efficiency, quality and reasonable cost is what makes this machine a great allrounder.
Pagoda type structure design and reinforcing ribs inside to ensure rigidity. All the mechanical connection areas are manually scraped to ensure long stay accuracy. All the key parts adopt top level brands, including spindle, linear guideway, ball screw, bearings, tool magazine, tool cylinder, guideway covers etc. Large span of Y axis guideways to keep all the X axis travel is supported. Intergrated ball screw housing ensure long stay accuracy. Pre-tensioned ball screw provides outstanding positioning and repeatability with virtually no thermal growth. Directly coupled servo motor eliminates any factors which will influence accuracy and efficiency.
Machine structure
-The contact ratio between spindle case and column increased to ensure spindle rigidity.
-1100mm wide machine body span and optimum supporting design can meet with fast feed of X and Y axis.
-Big size of “pyramid” column and with closed inner cavity to ensure low center but high rigidity support of Z axis.
Preloaded and double anchored ball screw
-Servo motor directly coupled ball screw.
-All the ball screws, linear guideway, bearings are well lubricated in time and ration.
-Y/Z axis adopt 45mm linear guideway while X axis adopts 35mm which make the rapid feed speed reach 48/48/32m/min.
-In order to eliminate thermal growth and increase accuracy, all axes are driven by high precision double anchored ballscrews. Also 5 rank high precision angular contacted bearing installed aside the ball screw and make pre-tension.
Shoulder carrying tool magazine
-Shoulder carrying tool magazine can ensure Z axis geometric accuracy and perfect stability, rigidity and the minimum deformation when column loaded with tool magazine weight.
Large flow coolant fluid
-Labyrinth style cover design to protect machine from scraps and cutting fluid.
-Standard equipped with inner side flushing system to remove scraps efficiently.
