INFINITELY VARIABLE SPINDLE SPEEDS Your lathe operators will get full value for you when using the Hardlnge variOible spindle speed because it is easy to operate. This cannot be said for the ordinary lathe with complicated featu res which ope r ators refuse to use because of the effort required to operate such machines. With the Hardinge HLV-H lathe the spindle speed may be Increased or decreased at the touch of a control button. Selecting the exact speed required can be done while the tool is cutting. It is easy to vary the spindle speed to obtain desired rate of production and specified surface finish.
SLOW SPEED M ED IUM SPEE D HIGH SPEED COARSE FEED M ED IU M FEE D FINE FEE D INDEPENDENT ELECTRIC VARIABLE FEEDS to obtain the exact feed for efficient chip removal and best surface finish. Your operators will produce more work with less effort In less time and with more precision on the Har- dlnge HLV-H lathe. The independent variable electric feed for carriage and cross slide provide complete freedom of operation. You are not tied down to con- vendonal rates of feed in relation to spindle speed.
With the machine in operation you simply turn the control knob The rate offeed can be changed instantly at any time, even when the tool is cutting, without wasting valuable production time stopping the machine to shift gears as is the case with slow conventional lathes. The Hardinge variable spindle speed drive and the H ardinge inde- pendent electric feed were developed by Hardinge and come to you laboratory tested and customer shop use approved . Neither is compli- cated which means little or no maintenance. F or examp le. electronic tubes are not used in either unit. A ll designs are basic and unde r stood by regular shop peop le. 5
