CNC can be configured to match skills
The concept behind a CNC system being introduced to 'Mini-Mill' machine tools is to enhance their capability and productivity by allowing the control to be configured to match existing skills.
By introducing its own-brand CNC-7 control XYZ Machine Tools brings the ease of use that is the hallmark of its ProtoTRAK-equipped manual/CNC mills and lathes to its two models of compact vertical machining centre, namely the XYZ Mini Mill 560 and XYZ Mini Mill 450 The concept behind the CNC-7 is a simple one: enhance the capability and productivity of the user by allowing the control to be configured to match existing skills

Large CNC lathes to be got for attractive prices
Value for money CNC machine tool specialist, XYZ Machine Tools in Devon, has expanded its range of CNC lathes with the introduction of the Vulcan series of turning centres.
This is particularly helpful to first-time CNC users who may otherwise be overwhelmed by CNC language, features and screen displays.
In essence, the CNC-7 can function in a straightforward two-axis mode, step up to a simplified three-axis operation and, when appropriate, access all the features available to maximise productivity.
Because the CNC-7 is a PC-based control, with a Pentium processor to handle the operator interface and a 32-bit Motorola processor to handle motion control, data storage, networking and memory are all expandable.

XYZ announces Open Houses in November and January
XYZ is holding an Open House at its showroom in Blackburn on 21 and 22 November 2001 and also at its showroom in Nuneaton on 23 and 24 January 2002.
And an open PC architecture will allow service and upgrades to be performed well into the future and at substantially lower cost than dedicated systems.
The menu-based question and answer format prompts the user when programming, with, for example, incrementing a tool to depth requiring only the cut increment and depths to be entered.
Compare this to the complex looping of sub-programs or the use of redundant commands usually required with G- and M-code programming - although the CNC-7 will accept these industry-standard codes, which means that compatibility with existing programs is not an issue.
The full-colour graphics displayed on the high resolution LCD screen allow verification of tool path and part program prior to commencing machining, with operator confidence guaranteed by the synchronised display between the graphics and machine movement - there is no discrepancy between what appears on the screen and what the machine actually does when the program runs.
And there are other safeguards, including a 'mid-program start' feature that allows a program to be verified graphically up to the point where machining should recommence.
At this point the operator can then switch over to 'run' mode.
Another key feature of the CNC-7 is its ability to search as many as 255 moves ahead in order to determine the directional changes that need to be implemented.
Once these changes have been made, the control dynamically adjusts the acceleration and deceleration slopes to maximise the machine's speed.
The control also makes use of an advanced feedback algorithm to minimise inaccuracies caused by corner rounding and following error, essential when high-speed milling.
Numerous other features, such as 'advanced trigonometry assist', 'sub-program looping and nesting', and 'speed and feed calculation' reflect XYZ's belief that the easier a control is to program, set-up and operate, the more productive a machine tool and its operator will become.
And, best of all, it avoids spending time and money on alternatives that merely complicate the issue without benefiting the bottom line. Request a free brochure from XYZ Machine Tools ...
