Frequently Asked Questions

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

The JTM-1050VS2 uses an R-8 spindle taper, which is one of the most common standards in vertical milling. It accepts collets ranging from 1/8" to 7/8", making it compatible with a wide variety of tooling for different milling operations.

Does this mill include a coolant pump with the internal coolant tank?

The JTM-1050VS2 features an internal coolant tank built directly into the base, which is designed for use with a coolant system. However, the coolant pump is not included and must be sourced separately.

What power requirements does the JTM-1050VS2 need?

This mill is powered by a 3 HP motor rated for 230/460V, 3-phase power. It is important to ensure your facility has the appropriate three-phase electrical service before installation.

What is the spindle speed range and how does variable speed operation benefit the user?

The JTM-1050VS2 offers a variable spindle speed range of 70 to 3,800 RPM. This wide range allows operators to dial in the optimal cutting speed for different materials - from slow speeds for tough metals to higher speeds for aluminum and softer alloys - without the need to change belt positions, saving time and increasing versatility.
