Deep-hole processing machine is the abbreviation of deep-hole processing machine tools. Deep-hole processing machine tools mainly include horizontal deep-hole drilling and boring machine, vertical deep-hole drilling and boring machine, deep-hole gun drill, deep-hole truss grinder.
According to the length of the workpiece, the deep hole machine tool chooses two kinds of processing technology: deep hole machine, short workpiece using oil feeder and hydraulic jacking; long workpiece using boring rod tail oil feeding, four-jaw chuck clamping. The feeder adopts an innovative spindle structure, which greatly improves the load-bearing performance and the rotating accuracy. The bed guide adopts double rectangular guideways suitable for deep hole processing machine tools, which have large bearing capacity and good guiding precision. The guideway has been quenched and has high wear resistance. It is suitable for boring and rolling in machine tool manufacturing, locomotive, ship, coal machine, hydraulic, power machinery, wind machinery and other industries, so that the roughness of the workpiece can reach 0.4-0.8 um.
Principles of Oil Selection for Deep Hole Processing Drilling Machines - Deep Hole Processing Manufacturers will tell you:
First point: Motion speed of deep hole drilling machine:
The higher the speed, the easier to form oil wedge. Low viscosity lubricant can be used to ensure the existence of oil film. If the viscosity is too high, the impedance and calorific value will be large and the temperature will be too high. When running at low speed, the load should be carried by the viscosity of oil. Lubricating oil with high viscosity should be selected.
Second point: Load-bearing capacity of deep-hole drilling machine
The higher the general load, the higher the viscosity of lubricating oil. The allowable carrying capacity of oil products should be considered in low speed and heavy load.
Third point:Working Temperature of Drilling Machine for Deep Hole Processing
When the temperature changes greatly, oil products with high viscosity index should be selected. Oils with high viscosity and flash point, good oil properties and oxidation resistance stability and corresponding additives should be selected when working at high temperature. Low temperature oil with low viscosity, low moisture content and low solidification point should be selected for low temperature operation.
Fourth point:Working environment of deep hole drilling machine
Oil products with strong emulsifying resistance, oiliness and rust resistance should be selected in humid and aerosol environments. Dust-proof seals should be paid attention to in environments with large dust. Oils with good corrosion resistance should be selected in the environment with corrosive gases.
