Description
Technical field
The utility model relates to machine tool mechanical field, particularly relates to numerically control grinder.
Background technology
Numerically control grinder utilizes grinding tool to carry out the lathe of grinding to surface of the work.Most grinding machine uses the emery wheel of High Rotation Speed to carry out grinding, minority be use other grinding tools such as oilstone, abrasive band and free abrasive to process, as honing machine, superfinisher, abrasive belt grinding machine, grinder and polishing machine etc.Numerically control grinder has again digital control plain surface grinding machine, numerical control centerless grinder, numerical control internal-external circle grinding machine, numerical control vertical universal grinder, CNC jig grinding machine, numerical control formation grinding machine etc.
Be suitable for the processing of Complex Different Shape part.Realize computer to control, get rid of human error.Accuracy compensation and optimal control can be realized by computer software.Machining center, turning center, grinding center, electric machining center etc. have tool magazine and tool changing function, decrease clamping times, improve machining accuracy.Digit Control Machine Tool makes machining equipment add the feature of flexibility.Flexible Manufacture is not only suitable for multi items, small batch is produced and is also suitable for producing in enormous quantities, and alternately can complete the processing of two or more different parts, adds the function of auto-changing workpiece, can realize unserviced operation at night.The flexible manufacturing system (FMS) be made up of a few number of units controlled machine (machining center) has the automated manufacturing system of more high flexibility, comprises the links such as processing, assembly and checkout
The material that grinding machine energy workhardness is higher, as hardened steel, carbide alloy etc.; Also can work brittleness material, as glass, granite.Grinding machine can do high accuracy and the very little grinding of surface roughness, also can carry out high efficiency grinding, as high-rate grinding etc.
Workpiece is owing to being subject to the restriction of own form, expect from down and machine, often need to carry out the multistage manufacturing processes such as milling, grinding, traditional processing method workpiece to be machined is arranged on the processing a kind of lathe completing an operation, again it is disassembled from this lathe, clamping to other lathe completes the processing of other operations, this not only needs to use multiple stage lathe, increase floor space, and in workpiece dismounting with the process of clamping again, certainly exist clamping and position error, machining accuracy is reduced; Dismounting and the process of clamping also have impact on working (machining) efficiency simultaneously, virtually add production cost, for those processing quantity greatly and the low product of price request, are difficult to meet processing request.
At present, the grinding machine that market is sold mainly contains internal and external grinding machine, surface grinding machine and curve surface grinder, is used for grinding inside and outside circle, plane and curved surface respectively.And need the workpiece often shape matching complexity of carrying out grinding, contain various curved surface, special-shaped border, hole, groove and die cavity etc., for the processing of these complicated surfaces, only be difficult to by a grinding machine, need by means of other forms of lathe, so just occurred the problem of above-mentioned machining accuracy, working (machining) efficiency and production cost.
Vertical paralleled surface grinding machine is generally used in Precision Machining, two high accuracy end faces of grinding work piece while of the end face of top lower two panels emery wheel, because the required precision of processing work is high, so, the design of grinding spindle is most important, and main shaft required precision is higher, operation is more stable.
Current double-ended grinding machine main shaft mainly adopts single-row angular contact ball bearing to combine, pairing uses, and installation and debugging are all inconvenient, and main shaft precision is also not easy to control, and assembling high-precision main shaft success rate is lower.Because grinding is stressed, after main shaft works long hours, precision easily becomes large, and precision keeps poor.
