Abstract
A kind of straight shank twist drill φ 1.35-1.95 that can improve production capacity, cut down finished cost, save material rolls ditch mill back of the body technological method for processing.It is to adopt groove to roll the processing mode of turning round extrusion without cutting.
Description
Affiliated technical field
It is the technological method for processing that a kind of groove does not have cutting that straight shank twist drill φ 1.35-1.95 of the present invention rolls ditch mill back of the body mode.At present, known φ 1.35-1.95 fluted drill groove processing is milling or two kinds of processing modes of grinding.Because milling or its processing cost height of grinding, production efficiency are low, so be difficult to accomplish scale production.
Summary of the invention
For improving existing processing technology, adopted the high four-high mill of production efficiency to roll and turned round the processing mode that pushes fluted drill ditch Slot shaping.Make its production capacity improve that 10 times, processing cost reduce by 35%, conservation of raw material 20%.
Fluted drill of the present invention is characterized in that its crystal grain has kept original state on the metallographic of metal, flute surfaces has uniform hardness, the heart portion that rigidity is big, very smooth surface, help iron filings flow and because the caused cutting temperature that flows is lower, so the wearability of the intensity of fluted drill, cutting edge is enhanced.
Indicated the position of fluted drill groove in the accompanying drawing.
Claims (1)
- Straight shank twist drill φ 1.35-1.95 rolls ditch mill back of the body technological method for processing, it is characterized in that: groove adopts to roll turns round extrusion without cutting processing, and its groove rolls turns round extrusion without cutting processing method prescription protection.
