我厂在加工一批橡胶硫化模具时(图1),由于模具是鼓形半圆凹模,要求在鼓形半圆凹模上有棱形和横直线条的图案,要求线条均匀,深浅一致(深度0.8毫米),并要有较高的光洁度。由于我厂无仿形铣床,我们革新用杠杆靠模法在普通铣床(X-61带立铣头)上加工。 I plant processing a number of rubber curing mold (Figure 1), because the mold is a drum-shaped semicircular die, requiring drum-shaped semicircular die with prismatic and horizontal lines of the pattern requires uniform lines, the same depth (depth 0.8 mm), and to have a higher finish. Due to the fact that our mill has no profile milling machine, we have revolutionized the use of lever-and-die methods on an ordinary milling machine (X-61 with vertical milling head).
