Merchandise Description

Deep hole drilling and uninteresting machine

Usage of the equipment: the device is a special products for drilling and dull deep gap of cylindrical workpieces. While unexciting, the oil supplied from the oil strain head get the metallic chips from the reducing area to the lantern and chip converyer in the CZPT of the headstock, and drilling adopt internal steel chips remving method (BTA strategy), the oil supplied from oil strain head remove the chips from the chopping area to the chips receiver in the again of the equipment by way of the innner hole of the drilling tube.
The mattress of the machine is rectangle quenched guide way which has large antiwear ability, the feed direct screw is mounted in the middle of the manual way. The clamp workpiece of the oil pressure head adopt servo motor so it is reputable and secure. The spindle of the oil pressure head has large concentricity with the spindle of the headstock. And the alter of the information bush is also hassle-free.
This is a simple functioning, high performance and surroundings protective deep hole unexciting equipment.

one. Clear the shaft, the inner and outer holes of the bushing, and the internal gap of the hub. Take away any oil, paint or grime, location the bushing on the hub, and match the half holes to make total holes (every complete gap will only be threaded on one aspect). Evenly oil the threads and points of set screws or the threads and heads of cap screws. Loosely location the screws in the threaded holes on the hub facet. Make certain the bushing is totally free on the hub. Snap the assembly onto the shaft and position it in the wanted position. Tighten the screws alternately and evenly right up until all are tight 5. Hammer the large stop of the bushing with a hammer and block or socket to steer clear of harm. The screw can now be turned a bit to the specified torque setting. Repeat this alternating hammering and screw retightening until the specified torque is attained. Fill all holes with grease to get rid of filth.
