Abstract

Usage: face grinding various materials mainly for flat grinding disk blanks on two-sided face-grinding machines of a semiautomatic device with a reduction in the grinding zone. Summary of the invention on the panshaybe, the grinding wheel with squeezed holes of the HRF supply of CO f to the cutting zone, connected to the faceplate With a chain for increasing the efficiency of the “loose tank in the panshaib, is formed the concentrically arranged annular grooves and nepecei-grooved and cruciform grooves recessed at its end face and the through channels in the grinding wheel are evenly distributed on the same edge, + nost as the annular grooves in the 3-il faceplate (/ С

Description

The invention relates to the mechanical processing of metals and alloys in face grinding; various materials are predominantly used for flat grinding of a disc Z. ZGOTOVO1- on two-sided semi-automatic grinding machines

Known prefabricated abrasive tools for mechanical encryption consisting of a face plate on the periphery of which abrasive segments are installed and channels are open with the channels for supplying coolant to the cutting center to the center of rotation of the tool, the conical body is attached, which has channels for supplying SOL to the segments. The body is made partitions forming cavities for receiving CO and directing it to the main channels of the segments A channel system is formed in the segment

The main longitudinal sloping and cute inclined channels Jloog CO t through the channel system enters the machining zone. The disadvantage of such a tool is that the channel system in the segment is located on one and side rotation and is open towards the rotation center Therefore, the SOF is supplied not to the most peripheral teppon, the strained segments of the segment performing the main cutting work, but to the internal ones with a lower heat density. Said, as well as +; the fact that the channel system is not closed in the volume of segments This suggests that most of the coolant does not fall into the contact zone of the segment with the workpiece and, therefore, the cooling efficiency when using such a tool is insufficient.

It is difficult to use the tool for double-sided grinding, as the workpieces to be grinded during processing can get lost in segments. The circle is drawn. It is difficult to use it on a stand with a horizontal spindle

The purpose of the invention is to increase the cooling efficiency with predominantly double-sided face grinding

In FIG. shows a general view of the device, Fig. 2 - faceplate plan in Fig. 3 - grinding cool plan

The face grinding device consists of a faceplate 1 with a reservoir for lubricating-cooling fluid and a grinding wheel flaxen on the faceplate 2 with through holes 3 for supplying coolant to the cutting zone associated with the faceplate capacity. The capacity in the faceplate is formed by the concentration with the circularly arranged circular digits 4 and the intersecting and cruciform grooves 5 The through mnaps in the grinding wheel are evenly spaced on those: circumference “the same as the ring tavangs in the faceplate

The coolant through the central hole b, the cross-shaped grooves 5, the annular grooves 4 and the through holes 3 in the grinding wheel is supplied under pressure to the cutting zone. The amount of fluid supplied to the grinding zone and its pressure are regulated by the capacity and pressure of the machine coolant supply system

Thus, when grinding, CO penetrates directly into the processing zone about “le + yes, and its most thermally stressed sections

The face grinding device increases the cooling efficiency, improves the removal of sludge from the cutting zone, the grinding wheel is much less greasy and requires fewer edits, the quality of the processed surface is improved.

Claims (1)

The claims The face grinding device comprising a faceplate with a reservoir for lubricating-falling liquid (coolant) and a grinding wheel fixed on the faceplate with through holes for supplying SOF into the cutting zone, connected with the faceplate capacity, characterized in that with a chain for increasing cooling efficiency, the capacity in the faceplate is formed by junts-made at its end. ring-shaped grooves and intersecting and cruciform grooves and through channels in the grinding wheel are located evenly on the same okru. bridge as ring grooves in n pan washer F (/ g, 2 Fig 3
