Designed for light and medium duty metal cutting applications, a range of CNC bridge-type milling machines offer an economical alternative to using routers and large milling machines.

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 CNC-7, with Siemens' 810D 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 24HP 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 1220mm by 2440mm to 2030mm by 3810mm, while X, Y and Z axes maximum travels are 3810mm, 2030mm and 760mm, respectively.

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

Repeatability on all three axes is 0.01mm, 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/5th 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.
