Boring machine classification, inspection standards and maintenance

For boring machines, in addition to knowing its safe operating procedures, what knowledge do we need to know? The answer is that the classification, inspection standards and maintenance of boring machines also need us to master, so let's introduce these knowledge in detail below. 1. Classification Boring machines can be divided into horizontal boring machines, floor boring and milling machines, diamond boring machines and coordinate boring machines. Horizontal boring machine: It is a kind of boring machine with many applications and wide performance, suitable for single-piece small batch production. Floor boring machine: The workpiece is fixed on the floor platform for processing. It is suitable for processing larger size and weight workpieces, and is generally used by heavy machinery manufacturers. Diamond boring machine: Use diamond or cemented carbide tools for processing, boring holes with high precision and small surface roughness at a small feed rate and a high cutting speed, which is suitable for mass production. Coordinate boring machine: It has a coordinate positioning device, which is suitable for processing holes with high requirements on shape, size and hole pitch accuracy. It can also perform scribing, coordinate measurement and scale work, and is suitable for small and medium batch production. 2. Inspection standard JB2253-85 'Parameters of coordinate boring machine'; JB3753-84 'Vertical shaft end of 3220 taper hole of vertical jig boring machine'; JB2255-85, ZBJ54022-89 'Accuracy and technical conditions of rotary table of coordinate boring machine'; JB2254-85 'Accuracy of jig boring machine'; JB/T2937-93 'Technical conditions of jig boring machine'; GB5289-85, JB4373-86, JB/T4241-93 'Accuracy and technical conditions of horizontal milling and boring machine'; ZBJ54023-89, JB/T5602- 91 'Floor milling and boring machine parameters and series profile'; JB/T5765-91, JB/T5601-91 'Horizontal fine boring machine parameters and series profile'; JB5564-91 'Horizontal fine boring machine accuracy'; JB /T54010- 93 'Horizontal fine boring machine technical conditions'; ZBJ52004-88, ZBJ51002-88 'horizontal fine boring machine, boring head accuracy and technical conditions'. 3. Maintenance The maintenance work of the boring machine mainly includes cleaning, lubrication and reasonable operation. Daily maintenance can be carried out in three stages, as follows: Before work: Check whether the various parts of the boring machine are in good condition and whether the handle positions are normal. Clean all parts of the boring machine, lubricate the guide rail surface directly, and start running at low speed for a certain period of time. Working: Operate correctly, and do not allow the boring machine to work overload. If the boring machine has abnormal conditions during work, it should be shut down immediately for inspection. After work: Clean all parts of the boring machine, move the moving parts of the boring machine to the specified position, and turn off the power. After the boring machine has been running for 800 hours, a first-level maintenance must be performed, which must be performed in a power-off state, including maintenance of the headstock, feed gearbox, workbench, guide rail, rear column, lubrication system, and electrical parts, except for this In addition, external maintenance is also required.
