Variable speed means you can dial in the exact RPM needed for your material and tool diameter without stopping to change belt positions, giving you smooth, stepless speed control for operations ranging from heavy face milling at low speeds to high-speed finish end milling.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eWhat does the Newall DP700 DRO add to this mill, and which axes does it cover?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eThe integrated Newall DP700 Digital Readout provides real-time positional display on all three axes  -  X (table longitudinal), Y (table cross), and Z (quill)  -  allowing you to precisely track and set cutting positions without relying solely on handwheel dials. This significantly reduces setup time, eliminates cumulative measurement error, and improves part-to-part repeatability.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eHow does the pneumatic power draw bar work, and why is it beneficial?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eThe pneumatic power draw bar uses air pressure to rapidly clamp and release R-8 toolholders in the spindle. Instead of manually spinning a wrench to tighten or loosen the draw bar, the operator actuates the pneumatic system with a button, dramatically speeding up tool changes and reducing fatigue during high-volume or production work.\u003c\/dd\u003e\n\u003cdt\u003e\u003cstrong\u003eDoes the JTM-4VS include a coolant pump, and how is the coolant system integrated?\u003c\/strong\u003e\u003c\/dt\u003e\n\u003cdd\u003eThe JTM-4VS features an internal coolant tank built directly into the casting base, which provides a clean, space-saving reservoir ready for connection to a coolant system. However, the coolant pump is not included and must be sourced separately. The built-in tank means no external reservoir is needed once a compatible pump is added.\u003c\/dd\u003e\n\u003c\/dl\u003e\n\u003c\/div\u003e","brand":"JET","offers":[{"title":"Default Title","offer_id":40249069404321,"sku":"JT9-691170","price":25046.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0398\/5188\/4705\/products\/691170_main_c856b143-a850-4eb8-a275-6343242813b1.png?v=1624988773","url":"https:\/\/factorydirectsupply.com\/products\/jet-691170","provider":"FactoryDirectSupply.com","version":"1.0","type":"link"}
