• Chrome-plated motor shaft with bearing support at end for enhanced durability and reduced runout
• Hardened and ground square vertical knee ways and cross ways deliver exceptional rigidity and repeatability
• Heavy duty motor drive rated at 3 HP, 230/460V, 3-Phase for powerful, reliable performance across demanding applications
• Large diameter quill is chromed (3-3/8") for wear resistance and smooth travel throughout 5" of spindle travel
• Precision bored and honed milling head ensures quality cuts and accurate spindle alignment
• Spindle head is internally cooled to maintain operating temperatures and extend component life
• One shot lubrication system simplifies maintenance and protects all critical sliding surfaces
• Three-stage power downfeed with automatic stop for consistent, repeatable quill operations
• Variable spindle speed range of 70 - 3,800 RPM via R-8 taper spindle accommodates a wide variety of tooling and materials
• High precision Class 7 bearings support the spindle for superior surface finishes and tight tolerances
• Internal coolant tank built into base for use with coolant system (coolant pump not included)
• 3-axis ACU-RITE 203 DRO with quill readout eliminates manual calculations and improves positioning efficiency
• X-axis powerfeed for effortless table traversing and consistent feed rates during longitudinal cuts
• Tolerance test sheet included to verify machine accuracy right out of the crate
• Backed by the industry-leading JET Two Year Warranty

Frequently Asked Questions

Does this mill include a coolant pump?

No. While the JTM-1050VS2 features an internal coolant tank built into the base for use with a coolant system, the coolant pump is not included and must be sourced separately.

What spindle taper does the JTM-1050VS2 use, and what collet sizes are compatible?

The JTM-1050VS2 uses an R-8 spindle taper and accepts collets ranging from 1/8" to 7/8", making it compatible with a wide variety of standard milling toolholders and collets.

What is the variable spindle speed range on this machine?

The JTM-1050VS2 offers a variable spindle speed range of 70 to 3,800 RPM, allowing operators to select the optimal speed for different materials, tooling diameters, and cutting operations.

How does the one shot lubrication system benefit the operator?

The one shot lubrication system allows the operator to lubricate all critical sliding surfaces - including the hardened and ground knee ways, cross ways, and lead screws - with a single action, simplifying routine maintenance and helping to extend the service life of precision components.
