VMC-1270L Vertical Machining Center: BT50 Power for Heavy Cutting

The VMC-1270L is the heavy-cutting model of VITOP Machinery's L series vertical machining centres. It pairs 1200 x 700 x 600 mm of travel with a BT50 spindle and an 18.5 kW motor, which places it in the class of machine you move up to when BT40 centres keep bogging down in wide facing cuts or deep pockets. This guide walks through the specifications and explains what each one means for daily production.

Spindle and Cutting Power

The headline specification is the BT50-Φ155 spindle driven by an 18.5 kW motor. Speed runs from 40 to 8000 r/min with a rated output torque of 143 N.m, so the machine holds full cutting force at low rpm, exactly where face mills and roughing end mills need it on steel and cast iron. That low-speed torque is the practical difference between a BT40 centre and this machine: you can run larger diameters, take deeper passes and let the motor pull instead of chattering.

Key Specifications at a Glance

Guideways, Ball Screws and Table

The axis design is a hybrid: X runs on 55-size roller guideways combined with sliding rails, and Y and Z use 45-size roller guideways with sliding rails as well. Roller elements give you fast, low-friction positioning; the sliding surfaces add damping when the cutter bites hard. That mix suits heavy roughing better than an all-linear-rail light-duty machine. Ball screws are 5010 on all three axes, a robust pitch for this class of load.

The worktable measures 700 x 1360 mm with five T-slots and takes workpieces up to 1000 kg. Distance from spindle end face to table spans 87 to 687 mm, and the spindle centre sits 785 mm from the column guideways, so tall fixtures and long parts still fit under the spindle nose.

Tool Magazine and Utility Details

A 24-tool magazine changes tools in 3.5 seconds and accepts holders up to Φ110 mm fully loaded or Φ200 mm when adjacent pockets are empty, with a maximum tool weight of 15 kg. That covers typical BT50 face mills and shell mills without compromise. The coolant tank holds 240 L, enough volume to keep temperatures stable during long roughing cycles.

Where This Machine Earns Its Keep

Think of jobs such as mould bases, gearbox housings, pump bodies, welded structural parts and aluminium platens. A shop running mixed batch work, for example a general parts manufacturer making brackets and housings in 1045 or HT250, can rough and finish on the same table instead of moving parts between a heavy mill and a finishing VMC. Fewer setups also mean fewer datum errors stacked into the final part.

Footprint and Planning Notes

The machine measures roughly 3650 x 3240 x 3200 mm and weighs about 10500 kg, so check your floor loading and plan a level foundation before delivery. Total electrical capacity is 35 KVA. If you are comparing models, match the 1200 mm X travel to your largest part plus clearance for fixtures, and confirm the BT50 tooling you already own can carry over.
