Frequently Asked Questions

What is the spindle speed range on the JET JTM-1050VS2?

The JTM-1050VS2 offers a two-range variable spindle speed system: 60 - 500 RPM in the low range and 500 - 4200 RPM in the high range, providing broad versatility for milling a wide variety of materials and using different tooling sizes.

Does the JTM-1050VS2 include a coolant system?

The machine features an internal coolant tank built into the base for use with an optional coolant system; however, the coolant pump is not included and must be purchased separately.

What makes the column castings on the JTM-1050VS2 different from standard mills?

The JTM-1050VS2 uses JET's proprietary certified Meehanite column castings, which are specifically engineered to provide enhanced rigidity and vibration dampening compared to standard gray iron castings, contributing to greater accuracy and longer machine life.

What power downfeed options are available on the JTM-1050VS2?

The machine is equipped with a three-stage power downfeed with automatic stop, offering quill downfeed rates of .0015, .003, and .008 IPR. This allows operators to select the appropriate feed rate for the material and operation, with the automatic stop ensuring repeatable depth control.
