CNC bridge mills offer an economical alternative to routers and large milling machines for producing large components under optional thermal control conditions.
Ideally suited to light and medium duty metal cutting applications, XYZ Machine Tools' new BRM CNC bridge mills offer an economical alternative to routers and large milling machines. Control is by way of the easy-to-use XYZ VMX-7 CNC, with Siemens' Shopmill conversational or G Code programming systems available as an option. Each of the six models in the BRM range is equipped as standard with a 24 hp high-torque, vector drive, spindle with a BT40 taper.

This provides speeds of 50-8000 rev/min as standard, with options of 12,000 rev/min, 15,000 rev/min or 24,000 rev/min.

Table sizes vary from 1220 mm by 2440 mm to 2030 mm by 3810 mm, while x, y and z axes maximum travels are 3810 mm, 2030 mm and 760 mm, respectively.

Rapid traverse rates of 25 m/min and a positioning accuracy of +/-0.025 mm over 300 mm (+/-0.12 mm over full travel) combine with a maximum component weight of 2270 kg to provide extremely cost-effective large machine performance.

Repeatability on all three axes is 0.01 mm, and machine construction features linear ways with axes protected by steel way covers.

Versatility is the hallmark of the BRM range, with options including a 24-station toolchanger, 4th axis, electronic spindle, digitising and thermal compensation.

Extended warranty and collision protection insurance can also be provided and, as with all XYZ machines, operator training is provided free-of-charge.
