Abstract: PURPOSE:To make various processes possible for one installation by providing a detachable and rotatable spindle at a work head and a tool head, positioning the work spindle along the axis and rotation direction at each index part, and moving both heads relatively to each other three-dimensionally. CONSTITUTION:A tool head 5 is adjusted for height in a direction Y, a spindle 16 is rotated continuously in a direction A1 to move a work head 4 in a direction Z1, and the outer circumference of a work W is grinded by a byte 43a. At this time, a spindle 42 is prevented from rotating at a member at a restricting part. The head 4 returns in a direction Z2 after that. The height of the head 5 is then adjusted, and a tool holder 143 is installed instead a tool holder 43, so a drill 143a faces an end surface of the work W. After rotation of the spindle 16 is restricted, a holder 40 is moved in the direction Za, while the spindle 42 is rotated continuously by removing the restricting member from a concave part in the spindle. A hole is thus bored in the axial direction in the work W.

Title: Semi-molten injection molding method of light metal member
Inventor: SAKAMOTO KAZUO
IPC: B22D17/30
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To stably obtain a desired strength of a member by specifying the relationship between relative density and solid phase rate of a molding product so as to perform molding. SOLUTION: When a molten light metal is injected and charged in a molding cavity of a molding die under a semi-molten condition so as to obtain a molding product, molding is done under a condition that the formula ρ>=0.1×α+96 will be satisfied where relative density of a molding product is δ[%] and the solid phase rate is α [%]. The solid phase rate is proportion of the solid phase against the entire molten metal (solid phase+liquid phase) in the semi-molten metal, which is numerally found as proportion (area ratio) of the solid phase portion against the entire observed area by observing a solidification structure of the molding product after injection. In this case, it is preferable that molding is done at the solid phase rate of α>=5[%].  Therefore, absolute volume to be solidified/shrunk after injection is reduced so as to maintain the relative density high, and viscosity of the molten metal is maintained high to prevent entrainment of gas, resulting in restraining dispersion of the relative density due to gas failure or the like.
