Techna-check 理想化的監控系統，令您的設備更穩定，更耐用

Ideal For Monitoring Tools On Single Spindle Heads. .

無接觸型刀具監控系統Non-Contact Tool Monitoring

該系統是通過PWM或VM傳感器對加工過程中軸向驅動電流或震動能量的變化實施監測，并將監測值同已知設定模型進行對比的方式實現監控功能。該系統適用于標準電機設備，交流伺服電極設備，變頻電機和直流電機設備監控，以及對軸向，夾具，工件或刀具的震動監測。

The Techna-Check® is a Tool Monitoring system designed to use the PWM series power transducers or the VM series vibration transducers to determine if there is a Broken, Dull or Missing tool. The PWM measures true power on a machine spindle or axis motor. It can be used on standard motors, AC servo motors,variable frequency drives and DC drives. The VM uses an accelerometer to monitor for excess vibrations on spindles, fixtures, parts or tooling.

主要特性

安裝簡易：不必機械改造，整個系統單元可方便安裝于電氣控制箱內。

Easy Installation

No mechanical modification of the machinery is necessary. The entire system mounts easily in your electrical cabinet.
調試簡單：調試軟件現場可實現所有運行設置，無需更多協助。

Easy Set-up

Easy to use set-up software eliminates the need for outside service, allowing you to make modifications and adjustments on the floor.
零能量監控：零能量監控可做皮帶斷裂或軸承損壞等狀況預警。

Idle Power Monitoring

Detection of idle power faults can alert you to broken belts or bad bearings.
磨損調整：系統”學入“功能可即時檢測磨損程度，同時進行相應修正和調整。

Adjusts to Tool Grind

The built-in “learn” function enables the system to compensate for differences in tool grind, improving the monitoring while reducing nuisance faults.

關鍵優勢

有效運行：破損，無加工監控能保障設備有效運行。

Proper Machining

The detection of missing or broken tools helps insure that the proper machining is being performed.
加工保證：狀態的即時監控保障加工工件合格率。

Improved Finish and Tolerance

Detection of tool wear and damage can help improve surface finish and tolerances.
機械保護：通過監控，可避免由于故障引起的主軸等機械破壞性的損壞。

Protection of Spindle and Feed Mechanism

By detecting catastrophic tool failure, TECHNA-CHECK can prevent serious damage to your head and feed mechanisms, not just at the station being monitored, but at down-stream stations where “chain reaction” effects can occur.
撞擊保護：避免由于斷裂引起的主軸，軸向類撞擊。

Crash Protection

Preventing crashes & tool breakage can help eliminate costly damage to your spindle.
斷裂保護：避免斷裂導致的不良工件產生。

Broken Tool Protection

Catching tool breaks minimizes scrap while guaranteeing perfect parts.
磨損保護：通過監控，可有效利用化其加工壽命。

Worn Tool Protection

Measuring for worn tools helps you maximize your tool life.
化壽命：監控可化利用較昂貴，提高生產成本效益。

Maximized Tool Life

By detecting for tool wear and damage, expensive tooling can be changed before the damage gets too severe. This detection also reduces dependence on hit or miss part counting schemes.
增加開機率：如此優越的過程監控系統，TECHNA-CHECK將令您的設備更穩定，更耐用。

Improved Up Time

工作原理 Principle of Operation

系統通過接受由設備發出的24DC或PROFIBUS信號啟動監控功能，取決于被監控對象，系統多可學入128個獨立的加工過程，監控刀具號的選擇由設備通過M代碼/宏程序代碼或PROFIBUS信號以24DC二進制代碼的形式將指令傳至監控系統。

The TECHNA-CHECK® interfaces to the machine control and is given a 24vdc or Profibus signal from the machine to tell the unit when to start monitoring. Depending on the system being used it will learn between 1-128 different cutting profiles. The tool selection is done via 24vdc binary inputs which are typically given using M-codes/ custom macro or by using Profibus.

監控系統接到啟動指令后，即開始監控功能，測量并確定相應驅動軸空運行能量消耗，以此建立空載模型，同時依據此模型設定高低限位值以判斷設備是否存在皮帶斷裂或軸承磨損情況。

Once the unit has been told to monitor, the system will measure the power that is used just to turn the spindle; this is labeled as the idle consumption within the image to the right. High and low limits can be set for the idle power to determine if a belt has broken or bearings are going bad in the spindle.

在監控系統學入切削過程的能量消耗狀態后（同時建立參考模型），當道具磨損時，其加工過程將消耗更多能量，當刀具斷裂時，能量消耗會短暫出現跳動峰值，如果在無刀具的狀態下進行加工，其消耗的能量將至零。在以上所論狀態下，Techna-check系統都會給出故障信息，并及時停止設備運轉。

The unit then learns the amount of power it takes to cut the material (labeled as measurement within the image to the right). As a tool becomes blunt (dull) the tool will begin to require more power to complete a machining cycle. When the tool breaks a short energy peak or spike is created and if no tool is present or the part has already been machined, the power consumption drops back to zero. If any of these situations occurs the TECHNA-CHECK will output a fault which will immediately stop the machine.

另外，系統可以監控“接觸點”，該功能適合應用于研磨和平衡設備中，在刀具向加工工件運行過程中可以高速行進，監控系統在刀具開始接觸到工件時發出指令，令設備控制刀具以慢速運行。

Additionally the TECHNA-CHECK can monitor “Touch Point”. This is used in grinding and balancing applications where the tool is fed into the part at a rapid rate. As soon as a rise above idle power is detected the system outputs a signal telling the machine control to slow the feed rate of the machine.
