Myford Super 7 Lathe

Myford Super 7 Lathe – not the usual item we offer, but an interesting piece of equipment.

Extract from Myford website – “The Myford Super 7 Lathe was introduced in April 1953, to complement the already very successful ML7 lathe. Whilst virtually identical in capacity, the Super 7 incorporated a number of features within its’ standard specification that made it a truly outstanding machine.

A spindle, supported in a taper bronze front bearing and a pair of angular contact ball races at the rear, which for its’ size, gives outstanding performance. This, coupled with 14 spindle speeds, gives an excellent and progressive speed range of 27-2105 rpm. Over 40 years later there are many machines being marketed as screw cutting lathes, which have bottom speeds of 200 rpm or so. This is just too fast for screw cutting. Other features are a back gear engagement lever, a countershaft clutch unit, a larger cross slide with block type gibs, a fully swivelling top slide, re-settable friction dials on both cross and top slides, a self ejecting tailstock and a leadscrew handwheel. Over the years, there have been a great number of modifications made to the original design as part of our continual policy of planned improvement. The major additions and changes are as follows:

The first quick change gearbox became available in 1955. The gearbox used soft gears and the leadscrew drive was on the right-hand side of the gearbox.

In 1956, hardened gears were fitted to the gearbox.

In December, 1956, the gearbox design was completely revised, and from gearbox number QC2501, the leadscrew passed through the drive and was taken from the left-hand side.

In June, 1958, from machine number SK 8128, the expanding sleeve clutch mechanism was changed to the current cone clutch. The change involved re-designed motor and headstock belt guards.

Customers are asked to note that we regret we are no longer able to supply spares for the early gearbox and clutch units.

In May 1959, from machine number SK 9176, the drip feed lubrication to the headstock was replaced with a wick feed system.

In August 1972, from machine number SK 108891B, the broad guide bed and saddle were introduced in preparation for the launch of the power cross feed models in March 1974, from machine number SK 115830.

In February, 1975, from machine number SK 120965, swing head oilite bushes were ground on the outside diameter.

In June 1975, from machine number SK 122657, the bronze cross slide feednut on power cross feed models was changed to hardened steel.

In December 1975, from machine number SK 126004, the power cross slide feedscrew was modified, requiring a larger counter bore in the corresponding micrometer dial.

In November 1977, from machine number SK 136311, the power cross feed apron was re-designed, incorporating an adjustable cam for the leadscrew half nuts.

In April 1977, from machine number SK 142981, the colour of machines was changed from grey to green.

Today, over 50 years after it was first launched, we are continuing to improve the Super 7. Apart from those items previously stated, we can supply almost every spare part for these lathes.”

Serial number of this Myford Super 7 Lathe is SK168794M, making it a post 1994 model.
