Internal Grinder Internal Grinder divided into general and the universal grinder. Universal grinder which is the most widely used grinder. The inner grinder can grind a variety of shaft and sleeve type work within the cylindrical surface, conical surface and stepped inside the shaft surface and so on.
The main components grinder for bed. The bed is the foundation bearing grinder, grinding wheel mounted on its top shelf, table, headstock, tailstock and horizontal saddle and other components. So that these parts remain accurate relative position at work. reinforced concrete cutting wheels Bed inside the body is used as an oil tank of hydraulic oil. Head frame for installation and clamp the workpiece and the workpiece driven by rotation of the head frame in the horizontal plane can be counter-clockwise 90 °. For supporting the inner circle abrasive grinding wheel spindle bore. Inner circle grinding spindle is driven by a separate motor. Wheel rack for supporting and driving the high-speed rotation of the wheel spindle. Wheel rack mounted on the saddle, when the need is short conical surface grinding wheel frame can be adjusted to a certain angle in the horizontal plane position ± 30 °. Tailstock and headstock top together supporting the workpiece. Saddle and cross feed mechanism rotating infeed handwheel. Can drive the saddle on its wheel frame for infeed movement transverse feed mechanism. Bench consisting of two layers. A rotary table rotatable around an angle in the horizontal plane of the lower table (± 10 °)? Small taper length to conical grinding surface, is mounted on the table at the headstock and tailstock. They can be together with the bench for vertical reciprocating movement along the rail bed. Machine uses: general accuracy level within a universal grinder, machine accuracy IT6, IT7 level. Machining surface roughness Ra of the surface can be controlled stainless steel flap disc within the range of 1.25 and 0.08μm. Universal grinder can be used within the inner cylindrical surface of the inner cone surface finishing, although productivity is low, but because of the universal grinder common good, is widely used in single and small batch production workshop, tool shop and machine shop .
