As preferably, described contour support pad is cylinder or polygon prism or cuboid, and contour support pad below magnechuck, keeps magnechuck stable equilibrium with minimum number formal distribution.Contour support pad makes to have space between magnechuck and work top with the contact form of a face or short-term, this space provides the area of dissipation of magnechuck, in the time of liquid feeding grinding, cooling fluid also can, from this space natural flow, dissipate the caloric value of magnechuck as early as possible.
As preferably, between described front console and rear lathe bed, be provided with contiguous block.The precision of grinding machine is one higher in machined, and the stability of complete machine is the basis that guarantees this machining accuracy, and contiguous block makes front console and rear lathe bed merge one.
As preferably, described longitudinal driving mechanism comprises decelerator, and decelerator is vertically arranged on column by support.Longitudinal driving mechanism provides the power that vertically moves of column, and motor, decelerator move with column.Decelerator is vertically installed the horizontal space position of reducing complete machine, makes said device features rational structure compactness.
As preferably, the lower end of described decelerator is provided with longitudinal gear, and rear lathe bed is provided with longitudinal rack, and longitudinally gear engages with longitudinal rack.The column of the technical program vertically moves and adopts gear, rack-driving mode, to obtain stable, lasting power transmission.
As preferably, described bistrique frame is by horizontal servomotor control traverse feed, and planker one side is connected with bistrique frame, and planker opposite side is connected with vertical guide rail by vertical guide rail slide block, and by vertical servomotor control vertical feed.Servomotor is the indirect speed change gear of a kind of subsidy motor, can make control rate, positional precision very accurate, voltage signal can be converted into torque and rotational speed to drive control object; Precision aspect has realized the closed-loop control of position, speed and moment; And column, bistrique frame, planker are low cruise, the low cruise smoothness of servomotor is high.
As preferably, described column bottom is provided with longitudinal rail slide block, and longitudinal rail and longitudinal rail slide block cooperatively interact.Guide rail in this programme all adopts linear rolling track form, is combined with steady, high accuracy fit system with longitudinal rail in column bottom.
As preferably, the height of described contour support pad is 5mm～15mm.Select contour support pad optimum height according to the model of the size of work top or equipment, both guaranteed the stability of work top, there is again good radiating effect.
Effective effect of the present utility model is: be ground product and work top for maintaining static parts, without kinetic equation loss, be applicable to the grinding of large-scale or the larger workpiece of weight; The grinding energy of the larger product of length is realized to automatic error correction completely; Contour support pad design between magnechuck and work top, has avoided the magnechuck mismachining tolerance of bringing to workpiece of generating heat.
