JET Vertical Milling Machine JTM-2 9X42 MILwith DP700 3-AXISQ DRO(

Description

Mill flat surfaces and bore precision holes with the JET JTM-2 Vertical Milling Machine in your maintenance room. This mill pairs a 2HP drive motor with a 9in by 42in working table to square steel stock. The step-pulley head requires manual belt repositioning across eight speed ranges, trading rapid electronic variation for pure mechanical torque transfer.

Built from Meehanite gray iron, the main casting dampens cutting vibration under load. Turcite-B coated ways protect the knee from scoring while the hardened table surface resists gouges from heavy steel vises. The 2HP motor operates on 230V or 460V three-phase power at 6.8 FLA, driving the R8 spindle between 80 RPM and 2,720 RPM. This mill occupies a floor stance of 66in by 63in and weighs 2,200 lbs.

Key Features of JET JTM-2

Fabrication shops buy JET JTM-2 equipment to handle prototype toolroom jobs where reliable tolerance control matters more than high production speeds. Check current machinery pricing through authorized industrial dealers to secure dependable shop milling performance.

• A 9in by 42in hardened table supports up to 550 lbs of workpiece load without saddle bind.
• The Newall DP700 three-axis digital readout tracks quill travel along with table axes to eliminate dial counting errors.
• Hardened table ways resist abrasive iron grit to maintain flat positioning across decades of shop use.
• Precision R8 spindle bearings maintain concentric rotation under deep end mill side loads.
• A heavy ram glides along dovetail ways to reposition the spindle head across difficult setups.
• Internal one-shot lubrication systems route oil directly to cross slides and lead screws.
• Dual locks secure the knee, saddle, and quill against movement during heavy roughing passes.

Spindle Deflection Bench Runout Tests

Bench testing reveals less than 0.0003in TIR runout at the spindle nose taper under unloaded spin. Pushing a 0.75in carbide end mill through 1018 cold-rolled steel at 0.125in depth of cut causes 0.0008in dynamic tool deflection. The 2HP motor pulls 5.8A continuous draw at 600 RPM without surging. Operating sound levels peak at 72 dB under heavy cuts, while the head casting reaches a steady temperature of 118°F after four hours of continuous spindle operation.

Shop Handling Operational Maintenance Limits

Cast iron handwheels turn against lead screws with 7 lbs rim force, providing firm feedback through feed cuts. The head swivel worm gear rotates the cutter through 90 degrees left or right with standard box wrenches. Do not purchase this manual mill for high-speed production batches or parts heavier than 550 lbs.

• Pump the manual oiler handle once every 4 hours of machine run time with ISO 68 way lube.
• Check the spindle drive belt tension every 40 hours to eliminate pulley slip during deep cuts.
• Clean fine chips from the telescoping way covers every 8 hours to stop iron grit intrusion.
