自制迷你车床 设计简介 思路USING STANDARD PARTS and stock
materials that are available almost
anywhere， you can build this metal-
working lathe with only a few tools.
Because of simplification of the assembly
in order to make the unit easy for anyone
to build， the lathe as pictured and
detailed cannot be rated as a precision
tool. It is simply designed to do practical
work within reasonable limits. As
detailed， the lathe swings 4¼” over the
bed and takes 10” between centers.
Standard pipe and fittings are used to
form a frame on which the headstock，
tailstock and bed are fitted.
The first step is to assemble the pipe an
fittings. Do this before any other parts
are made or stock cut to dimension. Th
reason for this first step is that in the
manufacture of standard pipe there are
allowable variations and some changes
dimensions of lathe may be necessary
because of these variations. The pipe
assembly consists of one 14” length of
l½” pipe， two close nipples， two tees， tw
floor flanges and one pipe plug (optiona
for closing the tee at the headstock end
of the assembly.
