Operating procedures of the hottest ordinary lathe

Operating procedures of ordinary lathe

inspection before startup

add appropriate lubricating grease according to the lubrication chart of the machine tool

check that all electrical facilities, handles 9, transmission parts, protection and limit devices are complete, reliable and flexible

all gears should be at the zero position, and the belt tightness should meet the requirements

metal objects must be stored directly on the bed surface to avoid damaging the bed surface

the processed workpiece is free of mud and sand, so as to prevent mud and sand from falling into the carriage and damaging the guide rail

before clamping the workpiece, the empty car test run must be carried out, and the workpiece can be installed only after confirming that everything is normal

operating procedure

after finishing the workpiece, start the lubricating oil pump first to make the oil pressure meet the requirements of the machine tool

when adjusting the exchange gear carrier and change gear, the power must be cut off, all bolts must be tightened after adjustment, the wrench should be removed in time, and the workpiece should be disconnected for trial operation

after loading and unloading the workpiece, remove the chuck wrench and the floating object of the workpiece immediately

the tailstock and rocker of the machine tool shall be adjusted to the appropriate position according to the processing needs, and fastened or clamped

the workpiece, cutter and fixture must be firmly clamped, and the floating force tool must extend the guide part into the workpiece before starting the machine tool

when using the center frame or tool heel, the center must be adjusted properly, and there must be a good lubrication and support contact surface

when processing long materials, the main shaft is directly connected with the motor, and the lead screw also changes with the change of the motor. The protruding part should be too large. If it is too long, install the support frame and hang the danger mark

when feeding, the knife should slowly approach the workpiece to avoid collision; The speed of the carriage back and forth should be uniform. When changing the tool, keep a proper distance between the tool and the workpiece

the cutting turning tool must be fastened, and the extended length of the turning tool generally exceeds 2.5 μ of the tool thickness

when processing eccentric parts, there must be appropriate counterweights to balance the center of gravity of the chuck, save energy and improve production efficiency

protective measures must be taken for workpieces with chuck stuck beyond the machine body

the adjustment of tool setting must be slow. When the tool tip is 40 ~ 60mm away from the processing part of the workpiece, manual or working feed should be used, and the upper rapid feed should be used to directly eat the tool

when polishing the workpiece with a file, the tool holder should be retreated to a safe position, and the operator should face the chuck, with his right hand in front and his left hand behind. The workpiece with keyway and square hole on the surface shall not be processed with file

while polishing the workpiece with emery cloth, the operator shall pull both ends of the emery cloth with both hands according to the posture specified above. It is forbidden to grind the inner hole with fingers holding abrasive cloth

during automatic tool feeding, the small knife holder should be adjusted to be flush with the base to prevent the base from touching the chuck

when cutting large and heavy parts or materials, sufficient machining allowance should be left

stop operation

cut off the power supply and remove the workpiece

the handles of each part shall be knocked down to the zero position, and the tools and instruments shall be counted and cleaned

check the condition of each protective device

precautions during operation

it is strictly forbidden for non staff to operate the machine tool

it is strictly forbidden to touch the cutting tool, the running part of the machine tool or the rotating work during operation

it is allowed to use the emergency stop. In case of emergency, after stopping with this button, it should be rechecked according to the regulations before starting the machine tool

unless otherwise specified, the guide rail surface, screw rod, polished rod, etc. of the upper pedal lathe shall be allowed to use feet instead of hand operating handles

for parts with sand holes, shrinkage holes or keyways on the inner wall, use a triangular scraper to cut the inner hole

the compressed air or liquid pressure of pneumatic or hydraulic chuck must reach the specified value before use

when turning slender workpieces, the protruding length on both sides in front of the head of the machine exceeds the diameter, which can support 0.2% of the full load of the sensor ⑴ 00% Curve optional: multiple curves such as stress-strain, force elongation, force time, force strain, strength time, etc. can be selected. When the curve is more than 4 × 4, the top should be used according to the process regulations. Center frame or heel rest support. When protruding behind the head of the bed, protective devices and warning signs should be added

when cutting brittle metals or chips that are easy to splash (including disc cutting), protective baffles should be added, and operators should wear protective glasses
