| Drake Manufacturing has developed a compact vertical thread mill for high production threading. Designated the DRAKE GS:VTM-LM, the machine will thread mill internal and external diameters, right or left hand threads, single or multiple leads to full depth in production quantities with fast cycle times.
Its compact vertical layout minimizes floor space, and with simplified manual or automatic loading and unloading, the machine is easily integrated into a manufacturing cell environment.
The vertical workhead (C-Axis) employs a synchronous AC torque motor with an 8-million count encoder that allows precise spindle control -- including indexing of parts — so that threading holes on a bolt circle can be accomplished if needed. C-Axis work rotation speed is 50-500 rpm. In standard configuration, the maximum part diameter is 3”.
The GS:VTM-LM has a heavy, rigid polymer/mineral-filled base to dampen vibration and enhance cutting stability. Its spindle slide (A-axis) has a servo-controlled helix with a +/- 5° range.
Linear motors control the Cutter Radial In-Feed Slide (X-Axis). The slide is fitted with long life, precision preloaded linear roller ways providing higher stiffness and more accurate positioning than Vee or flat ways.
Both high-speed steel and carbide cutters can be used. The cutter spindle has through-coolant capability and available automatic tool changer.
As with all Drake machines, the GS:VTM-LM is delivered with PartSmart™ Programming. No customer programming is required. To run parts, the operator enters part-specific variables into the menu screens and the control does the rest. Part changeovers can be accomplished in as little as 15-minutes.
