Product Description

With a precise understanding of the relevant industry, we are counted as the top most manufacturer and supplier of a premium quality Deep Hole Pull Boring Machine. This finds its application in different industries such as automotive, construction, oil and engineering. The machine is used to dig out deep hole and is widely known for its optimum performance. Our valued clients can avail this Deep Hole Pull Boring Machine from us at highly competitive prices.

Basic Function of Deep Hole Pull Boring Machine

The work on internal hole pull boring, rolling and expand pressing can be achieved by deep hole heaving boring machine. When the machine starts operating, the workpiece will be in static position not rotary, infeeding and cutter rotary, the trimming fluid will be provided in the trimming area via a device, lubricating and cooling the trimming place and take the chips away. But when deep hole heave boring functions, it accepts mechanical chip elimination technique, by doing so the chips are released via the front chips box.

Accuracy of the Machine

  • In rough boring the diameter precision and roughness of surface is IT9-10 and Ra6.3, accordingly.

  • Precision boring provides hole diameter exactness IT8-9 and surface unevenness Ra3.2.

  • Rolling pressing offers accuracy in hole diameter IT8-9 as well as surface roughness Ra0.2.

  • The exit screwness and straightness is less than 1/1000mm and 0.15/1000mm, respectively.

Processing Efficiency of Machine

The normal speed of cutting is 50-150m/min. It can be adjusted in compliance with cutter's material, workpiece material and cutter's construction. Whereas, the usual sped of infeed is 5-500mm per 60 seconds and also can be altered as per the requirement.

During the operation of boring, the optimal processing finish limit on one side is less than 10mm. The speed can be regulated as per workpiece condition, the cutter's construction and cutter's material.
