CHOTEST MT21 Series, High-Efficiency and Accurate Wireless Ball Stick Meter
The MT21 wireless ballbar tester from Zhongtu Instruments provides you with a simple, fast, economical, and efficient solution for machine tool performance testing. It is designed to quickly and cost-effectively test and improve machine tool performance and enhance processing quality.
Our Advantages
Functional Features
Simple and efficient
The measurement software streamlines the operation process, automatically generating machine tool running programs. A single simple setup enables testing of circular trajectories across three orthogonal planes, with a single performance test taking only 10-15 minutes.
Powerful diagnostic capabilities
Comprehensive diagnostic reports offer powerful diagnostic capabilities, providing you with a comprehensive and professional assessment of machine performance. Taking a 360-degree measurement on the XY plane as an example, the following can be assessed: reverse clearance X, reverse clearance Y, reverse jump X, reverse jump Y, lateral clearance X, lateral clearance Y, periodic error X, periodic error Y, servo mismatch, verticality, straightness X, straightness Y, proportional mismatch, scale error X, scale error Y, pitch X, pitch Y, feed rate, center offset X, center offset Y, position tolerance, best-fit radius, and roundness.
Wireless operation
Data transmission is transmitted via a wireless Bluetooth connection to a laptop, reducing the need for cables and enhancing convenience.
Software Introduction
MT21 measurement software provides a wizard-based operation process that allows you to quickly and easily complete the above circular trajectory tests. The collected data can be automatically generated into text and graphic format analysis reports in accordance with GB17421-4, IS0230-4, ASMEB5.54, and JISB standards, and the overall measurement values for position accuracy (roundness, roundness deviation) can be calculated, thereby achieving a true spatial analysis of the machine tool.
