Basis of Presentation	'
	NOTE 1 – BASIS OF PRESENTATION:
	Graham Corporation’s (the “Company’s”) Condensed Consolidated Financial Statements include (i) its wholly-owned foreign subsidiary located in China and (ii) its wholly-owned domestic subsidiary located in Lapeer, Michigan. The Condensed Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”) for interim financial information and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X, each as promulgated by the Securities and Exchange Commission (“SEC”). The Company’s Condensed Consolidated Financial Statements do not include all information and notes required by GAAP for complete financial statements. The unaudited Condensed Consolidated Balance Sheet as of March 31, 2013 presented herein was derived from the Company’s audited Consolidated Balance Sheet as of March 31, 2013. For additional information, please refer to the consolidated financial statements and notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2013 (“fiscal 2013”). In the opinion of management, all adjustments, including normal recurring accruals considered necessary for a fair presentation, have been included in the Company’s Condensed Consolidated Financial Statements.
	The Company’s results of operations and cash flows for the three and nine months ended December 31, 2013 are not necessarily indicative of the results that may be expected for the fiscal year ending March 31, 2014 (“fiscal 2014”).

Revenue_Recognition

Text Block [Abstract]	'
Revenue Recognition	'
	NOTE 2 – REVENUE RECOGNITION:
	The Company recognizes revenue on all contracts with a planned manufacturing process in excess of four weeks (which approximates 575 direct labor hours) using the percentage-of-completion method. The majority of the Company’s revenue is recognized under this methodology. The percentage-of-completion method is determined by comparing actual labor incurred to a specific date to management’s estimate of the total labor to be incurred on each contract. Contracts in progress are reviewed monthly, and sales and earnings are adjusted in current accounting periods based on revisions in the contract value and estimated costs at completion. Losses on contracts are recognized immediately when evident. There is no reserve for credit losses related to unbilled revenue recorded for contracts accounted for on the percentage-of-completion method. Any reserve for credit losses related to unbilled revenue is recorded as a reduction to revenue.
	Revenue on contracts not accounted for using the percentage-of-completion method is recognized utilizing the completed contract method. The majority of the Company’s contracts (as opposed to revenue) have a planned manufacturing process of less than four weeks and the results reported under this method do not vary materially from the percentage-of-completion method. The Company recognizes revenue and all related costs on these contracts upon substantial completion or shipment to the customer. Substantial completion is consistently defined as at least 95% complete with regard to direct labor hours. Customer acceptance is generally required throughout the construction process and the Company has no further material obligations under its contracts after the revenue is recognized.

	NOTE 3 – INVESTMENTS:
	Investments consist solely of fixed-income debt securities issued by the U.S. Treasury with original maturities of greater than three months and less than one year. All investments are classified as held-to-maturity, as the Company has the intent and ability to hold the securities to maturity. The investments are stated at amortized cost which approximates fair value. All investments held by the Company at December 31, 2013 are scheduled to mature on or before March 27, 2014.

Inventories	'
	NOTE 4 – INVENTORIES:
	Inventories are stated at the lower of cost or market, using the average cost method. For contracts accounted for on the completed contract method, progress payments received are netted against inventory to the extent the payment is less than the inventory balance relating to the applicable contract. Progress payments that are in excess of the corresponding inventory balance are presented in the line item “Customer deposits” in the Condensed Consolidated Balance Sheets. Unbilled revenue in the Condensed Consolidated Balance Sheets represents revenue recognized that has not been billed to customers on contracts accounted for on the percentage-of-completion method. For contracts accounted for on the percentage–of–completion method, progress payments are netted against unbilled revenue to the extent the payment is less than the unbilled revenue for the applicable contract. Progress payments exceeding unbilled revenue are netted against inventory to the extent the payment is less than or equal to the inventory balance relating to the applicable contract, and the excess is presented as customer deposits in the Condensed Consolidated Balance Sheets.
	Major classifications of inventories are as follows:
		December 31,		March 31,
		2013		2013

Commitments and Contingencies	'
	NOTE 11 – COMMITMENTS AND CONTINGENCIES:
	The Company has been named as a defendant in certain lawsuits alleging personal injury from exposure to asbestos allegedly contained in products made by the Company. The Company is a co-defendant with numerous other defendants in these lawsuits and intends to vigorously defend itself against these claims. The claims are similar to previous asbestos suits that named the Company as defendant, which either were dismissed when it was shown that the Company had not supplied products to the plaintiffs’ places of work or were settled for immaterial amounts.
	As of December 31, 2013, the Company was subject to the claims noted above, as well as other legal proceedings and potential claims that have arisen in the ordinary course of business.
	Although the outcome of the lawsuits to which the Company is a party cannot be determined and an estimate of the reasonably possible loss or range of loss cannot be made, management does not believe that the outcomes, either individually or in the aggregate, will have a material effect on the Company’s results of operations, financial position or cash flows.

	NOTE 12 – INCOME TAXES:
	The Company files federal and state income tax returns in several domestic and international jurisdictions. In most tax jurisdictions, returns are subject to examination by the relevant tax authorities for a number of years after the returns have been filed. The Company is subject to examination in federal and state tax jurisdictions for tax year 2013 and tax years 2009 through 2013, respectively. The Company is subject to examination in the People’s Republic of China for tax years 2011 through 2013. During the third quarter of fiscal year 2014, the U. S. Internal Revenue Service (“IRS”) examination of tax years 2011 and 2012 was completed. Based upon the results of the IRS examination, the Company reduced its liability for unrecognized tax benefits by $134. The liability for unrecognized tax benefits was $0 and $134 at December 31, 2013 and at March 31, 2013, respectively.
	It is the Company’s policy to recognize any interest related to uncertain tax positions in interest expense and any penalties related to uncertain tax positions in selling, general and administrative expense. During the three and nine months ended December 31, 2013, the Company reversed provisions made in previous periods for interest related to its uncertain tax positions of $15 and $11, respectively, based upon the results of the IRS examination of tax years 2011 and 2012. During the three months ended December 31, 2012, the Company recorded $2 for interest related to its uncertain tax positions. During the nine months ended December 31, 2012, the Company reversed provisions that had been made in previous periods for interest related to its uncertain tax positions of $387 due to lower interest assessments by the IRS than expected. Including this reversal, the Company recorded $(323) for interest related to its uncertain tax positions during the nine months ended December 31, 2012. No penalties related to uncertain tax positions were recorded in the three-month or nine-month periods ended December 31, 2013 or 2012.
	In September 2013, the IRS issued final regulations affecting costs to acquire, produce, or improve tangible property and re-proposed regulations affecting dispositions of tangible property. The final regulations are effective for taxable years beginning on or after January 1, 2014. The Company has evaluated the final regulations and does not expect the adoption of the regulations to have a material impact on its consolidated financial statements.

Accounting Changes And Error Corrections [Abstract]	'
Accounting and Reporting Changes	'
	NOTE 14 – ACCOUNTING AND REPORTING CHANGES:
	In the normal course of business, management evaluates all new accounting pronouncements issued by the Financial Accounting Standards Board (“FASB”), the SEC, the Emerging Issues Task Force, the American Institute of Certified Public Accountants or any other authoritative accounting body to determine the potential impact they may have on the Company’s consolidated financial statements.
	In July 2012, the FASB amended its guidance related to periodic testing of indefinite-lived intangible assets for impairment. The amended guidance is intended to reduce cost and complexity by providing an entity with the option to make a qualitative assessment about the likelihood that an indefinite-lived intangible asset is impaired to determine whether it should perform a quantitative impairment test. The guidance also enhances the consistency of impairment testing among long-lived asset categories by permitting an entity to assess qualitative factors to determine whether it is necessary to calculate the asset’s fair value when testing an indefinite-lived intangible asset for impairment, which is equivalent to the impairment testing requirements for other long-lived assets. In accordance with the guidance, an entity will have an option not to calculate annually the fair value of an indefinite-lived intangible asset if the entity determines that it is not more-likely-than-not that the asset is impaired. The provisions of the amended guidance are effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012. The Company considered this guidance in performing its annual impairment testing of the indefinite-lived intangible assets. The adoption of the amended guidance is not expected to have a material impact on its consolidated financial statements.
	In February 2013, the FASB issued guidance related to the disclosure of amounts reclassified out of accumulated other comprehensive income. This guidance adds new disclosure requirements either in a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of accumulated other comprehensive income (“AOCI”) based on its source and the income statement line items affected by the reclassification. This guidance gives companies the flexibility to present the information either in the notes or parenthetically on the face of the financial statements, provided that all of the required information is presented in a single location. This guidance is effective prospectively for annual and interim reporting periods beginning after December 15, 2012. The Company adopted this guidance during the first quarter of fiscal 2014 and such adoption did not have a material impact on the Company’s Condensed Consolidated Financial Statements as it only changed the disclosures surrounding AOCI (See Note 13).
	Management does not expect any other recently issued accounting pronouncements, which have not already been adopted, to have a material impact on the Company’s consolidated financial statements.
