Frequently Asked Questions

What is the spindle speed range of the JET JTM-4VS, and what does variable speed mean for my work?

The JTM-4VS offers a spindle speed range of 60 to 4,200 RPM. The variable speed capability means operators can dial in the precise RPM required for different materials and cutting tools - from slow, heavy cuts in steel to fast finishing passes in aluminum - without changing belt or gear positions.

What digital readout system is included, and how does it benefit machining accuracy?

This mill comes equipped with the Newall DP700 Digital Readout (DRO) on the X and Y-axes. The DRO provides real-time, precise position feedback directly on the display, reducing the need to count handwheel turns and minimizing the risk of costly positioning errors during complex milling operations.

Does the internal coolant tank come ready to use with a coolant pump?

The JTM-4VS features an internal coolant tank built into the casting base for use with a coolant system. However, the coolant pump is not included and must be sourced separately if coolant delivery is required for your application.

What warranty coverage does the JET JTM-4VS carry?

The JET JTM-4VS is backed by an industry-leading two-year full service and parts warranty, providing confidence in the machine's long-term durability and performance. A tolerance test sheet is also included to verify accuracy right out of the box.
