Heidenhain will be displaying Acu-Rite products at Mach, including Vue, 200S and 300S DRO systems, the Millpwr CNC, and the SENC 150 and SENC 50 scales.

The Acu-Rite Vue one- to three-axis digital readout is an entry-level DRO system designed to optimise the performance and operation of manual milling, turning and grinding machines.

Displaying full text on a LCD display with software functionality as standard, the system is available as a ready-to-use package with high-end SENC 150 precision glass linear encoders.

Vue’s standard functionality includes job clock, feed rate display, absolute/incremental, near-zero warning, 16 tool offsets/diameters, preset and zero reset, trig calculator and instant inch/mm conversion in addition to content-sensitive help function.

Specific functions for milling include graphically supported bolt-hole pattern calculations and centreline calculation, while for turning the system also features ‘lock axis’ functionality, and instant radius and diameter compensation.

Linear and non-linear error compensation is quoted as up to +/- 9.999ppm.

The Acu-Rite 200S DRO can be quickly and easily configured for two- or three-axis milling, turning or grinding applications.

The 200S displays all prompts, instructions and help functions as text or graphics on the flat-screen 5.7in 320 x 240 resolution LCD display.

All standard routines are visible on the screen and graphics guide users through the questions.

For milling, the system is supplied as standard with bolt-hole pattern calculations for full and partial circles, with graphics, zero reset and preset features, tool diameter compensation and near-zero warning.

For, turning, the system features include taper turning functionality and 16 tool offsets that, when used with the axis lock feature, ensures tool deflection is reduced.

Grinding and general use applications for the 200S are based around the system’s zero reset, linear error compensation, instant radius-to-diameter and inch to mm conversions, as well as absolute/incremental display features.

RS232 port and workpiece probing functionality is provided as standard.

The Acu-Rite 300S two- to four-axis DRO has a colour screen, with extensive I/O capability and encoder inputs for four independent axes.

Capable of storing up to 1,000 blocks of information, the system can also accommodate data for 16 tools and 10 sub-datums.

System functionality also includes automatic trigonometry calculations and hole skewing routines.

It has a slim-line design with a diecast aluminium casing and plastic front cover.

Acu-Rite’s SENC 150 precision glass scale technology is based on the use of reflective light for measurement and a reader head mounted on its top face.

This scale features advanced roller bearing technology for reduced backlash and greater scale travel life.

The result is a high-precision scale – resolutions are 0.5, 1 and 5um – that is highly resistant to machine inaccuracies and vibration.

SENC 150 is available in lengths of 50mm to 3.4m and features Acu-Rite’s Position-Trac functionality, which allows operators to accurately and quickly re-establish workpiece zero from any position after a power interruption.

Once power is restored, the DRO reads a line pattern on the glass scale to recall the last known zero.

Also on show, the slim-line SENC 50 precision glass scale offers resolutions of 0.5, 1 and 5um and is available in lengths of 0.025 to 0.5m.

The Acu-Rite display will also showcase the intuitive two-/three-axis Millpwr CNC, a conversational system that requires no previous CNC experience and can be used as a full-function DRO or as a programmable CNC.

The control offers operator feedback and features such as bolt-hole/PCD cycles; rectangular, circle pocket and irregular pocket milling; island and boss features; spiral, ellipse, mirror image, rotate, repeat setup and 2-/2.5-D contouring; tool library; shrinkage scaling; trig and geometry calculator and power editing tools.
