Frequently Asked Questions

What type of spindle taper does the JTM-1050VS2 use?

The JTM-1050VS2 uses an R-8 spindle taper, a widely used standard in Bridgeport-style knee mills that provides broad compatibility with toolholders, collets, and end mill holders. The collet capacity range is 1/8 to 7/8 inch.

Is a coolant pump included with this machine?

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

What spindle speed range does the JTM-1050VS2 provide, and how is it controlled?

The JTM-1050VS2 offers a variable spindle speed range of 70 to 3,800 RPM, controlled through its variable speed drive system. This wide range makes the machine suitable for cutting a broad variety of materials and performing diverse milling operations.

How does the one shot lubrication system benefit machine maintenance?

The one shot lubrication system allows the operator to lubricate all critical machine ways, lead screws, and bearing surfaces simultaneously with a single pump stroke. This simplifies routine maintenance, helps ensure consistent lubrication, and extends the service life of precision components throughout the machine.
