请教高手支招
<p>数控内圆磨机床托板过大对磨削精度有没有影响（现在托板150公斤左右，4牛米滚珠丝杆）？要求内圆精度半丝，请教高手支招。forum/2008-04/1209132527451572.jpg<br /></p> 应该不会有问题，滚珠丝杆的话对进刀精度应该比较高了 <p style="text-indent:2em"><img src="http://img.blog.163.com/photo/lquMaU9jA1rSbFsYph8g6g==/1986650385624481933.jpg" border="0" alt="" /></p><p style="text-indent:2em">问题就是这样子，也不知道到底是哪一个环节出了问题。一连造了几十台，现在问题都是这个样，包括我们现在刚制造出来的球面磨床。也不知道是不是我们设计出了问题，床头这一块应该不会有问题，床身是用近2T 的钢铁焊接而成，上下台面是铸造件，选用在是抗撞击钢导轨。我们在装丝杆和导轨的技术不是特别成熟，也不清楚问题出在哪里。<img class="a_a c_c" height="240" src="http://img.blog.163.com/photo/D7cXTCnEgh4aMdbobyAMOQ==/916482524170179784.jpg" width="192" target="_blank" href="http://kis18891120.blog.163.com/prevPhoto.do?photoId=fks!082071093087082067083095086095092085083075092081085&albumId=-1" alt="" /><table style="width:24"><tbody><tr><td style="overflow-x:hidden;vertical-align:bottom"><div class="case brd01" id="wrapper_p_fks!082071093086089071092081094095092085083075092081085"><div class="item g_t_wrap"><div class="g_t_wrap" style="margin-bottom:2px;padding-bottom:2px"><span class="c07" id="name_fks!082071093086089071092081094095092085083075092081085" title="点击即可编辑" alt="点击即可编辑" style="font-weight:bold;font-size:14px">数控内球面磨机床</span><span class="g_t_left" id="_$_pho_edt_ico_fks!082071093086089071092081094095092085083075092081085" style="display:none;width:24;line-height:20px;position:static"><span class="c05" style="font:14px '宋体';cursor:pointer"><font color="#c81c00">[编辑]</font></span></span> </div><div class="imgwrap"><img class="a_a c_c" height="192" src="http://img.blog.163.com/photo/eSaLwH4-l4WHJK_1k83agg==/2552415088812543837.jpg" width="240" target="_blank" href="http://kis18891120.blog.163.com/prevPhoto.do?photoId=fks!082071093086089071092081094095092085083075092081085&albumId=-1" alt="" /></div><div class="desc col1 g_t_wrap c07"><span id="desc_fks!082071093086089071092081094095092085083075092081085" title="点击即可编辑" alt="点击即可编辑" style="font-size:14px;line-height:100%">数控内球面磨机床：<br /></span><span class="g_p_left"><span class="bd1c"><font color="#d6d7d7"></font></span> </span></div><div class="func" id="tool_fks!082071093086089071092081094095092085083075092081085"><div class="g_p_left c05 g_c_hand" style="line-height:14px"><a id="photo_man_fks!082071093086089071092081094095092085083075092081085" href="javascript:;" style="font-size:12px;text-decoration:underline">管理</a><span class="n_ n32" id="photo_man_ico_fks!082071093086089071092081094095092085083075092081085"></span></div><span class="g_p_left"><span class="n_ f9" id="_$_friend_access_l_fks!082071093086089071092081094095092085083075092081085" title="好友可见" style="display:none"></span> <span class="n_ f8" id="_$_private_access_l_fks!082071093086089071092081094095092085083075092081085" title="私密相片" style="display:none"></span> </span></div></div></div></td><td style="overflow-x:hidden;vertical-align:bottom"><div class="case brd01" id="wrapper_p_fks!087067087082088067082081080095092085083075092081085"><div class="item g_t_wrap"><div class="g_t_wrap" style="margin-bottom:2px;padding-bottom:2px"><span class="c07" id="name_fks!087067087082088067082081080095092085083075092081085" title="点击即可编辑" alt="点击即可编辑" style="font-weight:bold;font-size:14px">内圆磨床系列 M2110A</span><span class="g_t_left" id="_$_pho_edt_ico_fks!087067087082088067082081080095092085083075092081085" style="display:none;width:24;line-height:20px;position:static"><span class="c05" style="font:14px '宋体';cursor:pointer"><font color="#c81c00">[编辑]</font></span></span> </div><div class="imgwrap"><img class="a_a c_c" height="192" src="http://img.blog.163.com/photo/PvS4KVy8bnZMjpJyRX8ZWQ==/4844747299143897344.jpg" width="240" target="_blank" href="http://kis18891120.blog.163.com/prevPhoto.do?photoId=fks!087067087082088067082081080095092085083075092081085&albumId=-1" alt="" /></div></div></div></td></tr></tbody></table></p>
